CHAPTER II

MENTAL INFLUENCE BEFORE OPERATION

Much may be done during the preparation for operation to put the patient in the most suitable condition for the manifestation of healthy reaction of tissue and of normal convalescence. Many patients do not come for operation until their health has been somewhat impaired at least by the condition requiring operation. Not infrequently a good proportion of this impairment of health is due not so much to the lesion that is present as to the worry over it and the anxiety and solicitude which its development has occasioned. If the lesion is in connection with the digestive tract, this is particularly likely to be true, and nutrition will often have been sadly interfered with, not so much by direct influence of the pathological condition as by the unfavorable mental influence developing in connection with it.

We know now that it is perfectly possible for an indigestion which is entirely above the neck to make rather serious inroads upon the health of the patient, by producing dislike for food or at least such loss of appet.i.te as leads to considerable reduction in weight. In such cases there are often complications, such as tendencies to constipation, that still further impair health or at least reduce vitality and therefore hamper that healthy reaction which should occur after operation in order to a.s.sure normal convalescence.

Accessory Neuroses.--In many of these cases, even where there is a definite lesion present, the patient can be brought up to normal weight, or at least his condition can be greatly improved by medical treatment accompanied {750} by such attention to his state of mind as will neutralize its unfavorable influence. If he can be made to understand that a definite effort to increase weight and to bring back his strength will be of a.s.sistance in recovery from the operation, and that the reestablishment of certain habits of eating and caring for himself will do much to help in this, very desirable changes for the better in his general health may be brought about. This is ill.u.s.trated very well by what happens in certain incurable cancer cases. The patients often have lost considerable weight, even thirty to forty pounds, before an operation is decided on, and then when the operation is performed their cancer is found to be inoperable. After the exploration the patient is not told this, but is mercifully spared and is a.s.sured that now he ought to get better, since an operation has been performed. Such patients have been known to gain twenty, thirty, and in one case I believe over forty pounds as the result of the mental influence of this suggestion and the resumption of former habits of life to some extent at least, consequent upon the neutralization of the unfavorable state of mind into which they had sunk before through over-solicitude about themselves. If even the depressing effect of the toxins of cancer can thus be overcome, it is easy to understand how much can be accomplished when there is no such physical factor at work.

Dominant Ideas.--As a general rule, it must be recognized that patients may be, and indeed frequently are, besides their definite pathological conditions, under the influence of dominant ideas which must be recognized and as far as possible neutralized. Some of them have persuasions with regard to food and the amount that they can eat, others have removed many important nutritious articles from their diet and are quite sure that any attempt on their part to take such articles is sure to be followed by indigestion, and still others have habits with regard to the amount and the kind of fluids that they take at meals and between meals and, above all, the lack of fluids in their diet which need to be overcome. Unless such ideas are counteracted there is difficulty even in convalescence, and very often they have brought patients into physical conditions in which whatever pathological condition is present is emphasized by that over-attention which the nervous system is so p.r.o.ne to give to even slight sensations when the organism is in a state of lowered nutrition.

In not a few of these cases the bringing of the patient up to the normal condition of weight and health, and the removal of the influence of dominant ideas, will perhaps also remove many of the indications for operation. There are many patients, and especially such as are reasonably educated and have some leisure, who get certain of their organs on their minds and produce symptoms or emphasize such symptoms as are present until it seems as though an operation is the only thing that can lift their burden of discomfort and permit them to go on again with their work. We have all known of physicians who felt sure that they ought to be operated on for such conditions as gastric ulcer or duodenal ulcer, though subsequent developments in the case, when they were persuaded to put off operation and made to reform certain ill-advised habits, proved that no such lesion as they suspected had ever been present. Indeed, some of these physicians and even surgeons have insisted so much that surgical friends occasionally have operated on them and have found nothing to justify the operation.

{751}

Some of these states in connection with discomfort of various kinds in the abdomen have been discussed in the chapter on Abdominal Discomfort, and some ill.u.s.trations of useless operations given. We must not forget that there is a constant stream of pathological suggestion in the air at the present time, not only in medical journals, but even in the secular press, and that this concentrates the attention of patients on comparatively slight discomforts and leads to the exaggeration of them until even an operation seems a welcome relief for them.

Operative Persuasions.--While surgical operations are in practically all cases mutilations, they are absolutely necessary under certain circ.u.mstances, are often, indeed, life-saving, and there is no doubt that they have saved mankind a great deal of discomfort. Surgeons are agreed, however, that they are not to be performed unless they hold out a definite promise of physical relief. It is extremely important, then, that patients must not become persuaded of the need of an operation in their cases unless surgical intervention is really necessary. This is as true for physicians and even surgeons themselves, as I have said, as it is for the general public. Women are much more susceptible than men to operation suggestions, and since it has become fashionable to talk about _their_ operations, not only has the deterrent idea of surgical mutilation been greatly lessened, but there has actually developed in many of them a morbid fascination for a similar experience with all its attraction of attention and promised occupation of mind for the woman of leisure.

This phase of the necessity for favorable mental influence has been especially emphasized in the chapters on Gynecology. Unless, therefore, there are very definite indications, operations must not be performed, for they will relieve, as a rule, only for the time being, and further operations may have to be done to no purpose. Any physician of reasonably large experience has seen such cases. Patients get the idea of an operation as their one hope, and then nothing less than that will produce such diversion of mind as will bring relief of symptoms. It is important in these cases that such patients should not have operations suggested to them. Once the suggestion takes hold, they do not use their reserve energy in such a way as to help out effectively other remedies that may be given. They distrust all remedial measures, think that at most they can be only palliative, and so do not add to other forms of therapeutics the power of psychotherapy to cure them.

Besides the abdominal conditions, there are certain tuberculous conditions with regard to which this seems to be particularly true. I have seen enlarged cervical glands disappear without discharge when patients have taken up the outdoor life, and, above all, when they have gone out of the city and have lived the regime proper for those in whom tubercle bacilli are growing. If such patients, however, once become persuaded that their glands must be operated on, they are likely to need, if not active intervention, at least the discharge of material from their tuberculous lesions before they get well.

Operations of a radical character for tuberculosis used to be much more popular than they are now, when we are likely to think that nature can do more for tuberculous lesions in nearly all cases than the most skillful surgery.

Fractures and the Mind.--In such surgical conditions as fractures and dislocations, a change has come about in the mode of treatment, at least in many hands, that seems entirely physical in its effect, yet has undoubtedly {752} exerted important psychic influences favorable to recovery which deserve to be noted. In dislocations and fractures, and particularly the latter, it was the custom in the past to do the fractured limb up in bandages and then leave it until knitting of the bones, or, in dislocations, healing of the soft tissues, had taken place. Apparently it was forgotten that this eminently artificial condition was not conducive to that healthy reaction of tissues for reparative purposes which must be expected in these cases. Circulation was not so good because of the constrictive effect of the bandages; vitality not so high because of failure of nervous activity in absolute immobility; the return venous circulation was somewhat hampered because there were no contractions of muscles; and all the conditions were distinctly unfavorable, though nature was expected not only to maintain the health of the part, but bring about the added functions of repair. In spite of the more or less unfavorable conditions, nature was able, as a rule, to do so. Prof. Lucas Championere reintroduced the older method of treating fractures and dislocations more openly and of even using certain manipulations, pa.s.sive movements, and ma.s.sage in order to encourage the circulation and the natural vitality of the limb.

There is another phase of the influence of this mode of treatment that deserves to be recalled. When the fracture is hidden away for many days and the patient is not absolutely sure whether it is getting on well or not, solicitude or anxiety is awakened in some minds that prevents, or at least delays, normal healthy repair. It is well known by surgeons that fractures do not heal so well after accidents in which there has been considerable shock, or in which the simultaneous death of a friend seriously disturbs the patient's mind. Nor do fractures heal so well if the patient is worried about business affairs or seriously disturbed over family matters. Among sensitive patients, a state of mind not unlike that produced by worry or shock may develop as a consequence of the dread that the fracture may not heal properly, or that there may be deformity, or that when the surgeon removes the bandages he may find it necessary either to break it again or do something that would involve considerable discomfort.

These patients need rea.s.surance. If the surgeon sees the broken limb occasionally, and, by manipulation and pa.s.sive movements such as may properly be used, a.s.sures himself as to its condition, the patient's mind is much better satisfied and that inhibition of trophic processes which otherwise sometimes occurs is prevented.

Incisions and Suggestion.--Something of this same psychotherapeutic influence is noted with regard to the healing of incisions when these are not left without inspection too long. The newer surgical customs of comparatively few dressings, so that the wound may easily be inspected and the patient may be completely a.s.sured with regard to it, has undoubtedly had a good influence in bringing about more rapid repair. Air is the best environment for a healing as well as a healthy skin, and mental trust is best for the patient's power of repair. In vigorous individuals such repair will occur anyhow. It is in those of delicate health, neurotic disposition, and psychoneurotic tendencies, that rea.s.surances are needed. Often their physical condition is such that they need every possible aid in bringing about complete repair.

Their state of mind, then, must be noted carefully, and any inhibitory ideas that may be present because of over-anxiety as to how the incision is getting on must be removed. This does not mean that patients' whims should be yielded {753} to in the matter of over-solicitude about their condition, but that proper care should be taken to prevent inhibition of trophic influences through unfavorable mental states just as far as is possible. Most surgeons of experience do these things in the proper way by instinct from the beginning, or by a tactful habit, which develops in their surgical experience of adapting themselves to individual patients. It is well to realize, however, that such mental att.i.tudes are extremely important and must be deliberately treated by the surgeon.

Pseudo-rabies.--Certain conditions usually treated of as surgical have mental relations that are very interesting. There seems no doubt that in a certain number of cases pseudo-rabies occurs; that is, persons are bitten by a dog, become seriously disturbed over the possibility of rabies developing, and after brooding over this for a time their mind gives way and there is either a neurosis simulating many symptoms of true rabies, or a state of collapse from fright in which even death may take place. These cases are not frequent. Their occurrence is taken by some of those who are opposed to animal experimentation as a proof that rabies is always some such delusion, and that it is due to the exaggeration of the significance of dog-bites by the medical profession that the symptom complex known as rabies has come into existence. This is, of course, nonsense, and many true cases of rabies occur. Since, however, these other cases provide the opportunity for argument in the matter, it is all the more necessary that they should be recognized for what they are. When a patient has been bitten by a dog that has not died from rabies within three weeks after the bite, there is practical certainty that the animal did not have and could not communicate rabies. The cases of hydrophobia with long incubation periods are rather dubious, and the general impression now is that there has been subsequent infection. Patients who are in the midst of overwhelming dread of the development of rabies must be taken seriously and their cases treated by mental influence. Suggestion, instruction, and the neutralization of wrong ideas by reference to authorities in the matter, must be used to overcome the unfortunate state of mind which may, if allowed to continue and, above all, to develop, prove serious for the individual.

Pseudo-rabies is but a type, though the most serious and perhaps most frequent of what may be called surgical psycho-neuroses. There are others. Imaginary syphilis is an affection that often causes worry and trouble to patient and physician. _Herpes preputialis_ with mental symptoms is almost as bad. These are mental infections of various kinds. There are many neoplastic persuasions and toxic suggestions that must be treated with tact and firmness.

CHAPTER III

MENTAL INFLUENCE IN ANESTHESIA

Nowhere in the domain of surgery is the influence of the mind more important than in the production of anesthesia for surgical purposes.

It is well known that intense preoccupation of mind will make an individual completely anesthetic even for very severe injuries. In battle men frequently are severely wounded, yet do not know it, or at least have no idea of the extent of the wound and of the pain that ordinarily would be inflicted by it. In the {754} midst of panics, as during fires, or when crowds are trying to get out of buildings rapidly, people often suffer severe injuries and know nothing about them. The story of the woman who lost her ear in the theater panic and was quite unaware of it until her attention was called to it, is only one of many striking examples. Men have been known to walk round even with a broken leg, or with a dislocation with which it proved quite impossible for them to move, once their mental preoccupation for others ceased and they had time to think about themselves. Anesthetic incidents under conditions in which great pain might well be expected are not uncommon. It is evidently possible so completely to occupy the mind that pain sensations cannot find their way into the consciousness.

Pain and Diversion of Mind.--From very old times, attempts have been made to use this power of the mind to prevent pain, and often with some results. In preanesthetic surgery, minor operations were performed rapidly, beginning just after the patient's attention had been attracted to something else besides the thought of the operation.

Pain is, of course, much less tolerable and seems to the sufferer at least to be much more severe whenever the attention is concentrated on it. Specialists in nervous diseases, during the process of eliciting complaints of pain or tenderness while employing movements or manipulations, usually try to attract the patient's attention as much as possible to something else, in order to determine just how much genuine pain or tenderness is present. Often it is found that, while a part of the body is complained of as exquisitely tender or it is averred that a joint cannot, be touched or a limb moved without severe pain, when the patient's attention is attracted strongly to something else, deep palpations may be practiced and rather extensive manipulations can be made without complaint. In these cases very often the pain is not imaginary, but is slight, due to some physical basis, and has been very much increased by the concentration of attention on it. This part, at least of the pain, may be removed by an appeal to the mind. The principle is valuable when there is question of minor operations.

Surgeons have often taken advantage of this power of distraction of attention to relieve pain in surgical manipulations. The story is told of the French surgeon, Dupuytren, that he was called one day to see a lady whom he knew very well in order to determine the form of injury from which she was suffering. He found that she had a dislocation of the shoulder, and during the manipulations, in order to make his diagnosis, he almost inevitably inflicted considerable pain. She complained very bitterly and told him that she understood that he was very rough with his hospital patients, but he must not be rough with her. He had hold of her hand at the moment, and, just before grasping the arm in such a way as to make the manipulations necessary to reduce the dislocation, he slapped her face and told her that she must not talk to him while he was treating her. Needless to say, she was deeply shocked. Before her shock had pa.s.sed away, Dupuytren had completed the reduction of the dislocation, and in her preoccupation of mind she felt almost no pain. She remarked afterwards, however, that she had suffered so much mental anguish from his unexpected roughness that she was not sure whether, after all, she had been really spared in her feelings.

Hypnotic Anesthesia.--When, in the first half of the nineteenth century, {755} scientific attention was seriously attracted to hypnotism, it was hoped that this would prove an effective means of producing anesthesia during surgical operations or at least of greatly lessening pain. The hope was not disappointed. There was a discussion on the subject before the Medical Chirurgical Society of London in 1840, and in 1843 Dr. Eliotson wrote a work with the t.i.tle, "Numerous Cases of Surgical Operations Without Pain in the Mesmeric State." In 1846 Sir John Forbes wrote in his Review that "the testimony as to the value of hypnotism as an anesthetic is now of so varied and extensive a kind as to require an immediate and complete trial of the practice in surgical cases." At the end of that same year, ether as an anesthetic was introduced into England, and the first case was reported under the caption "Animal Magnetism Superseded," which shows how much attention the previous attempts at hypnotic anesthesia had attracted. After this, hypnotism was given up for anesthetic purposes except by a few enthusiastic students of it. These, however, succeeded in accomplishing much with it. Dr. Esdaile, in India, succeeded in doing all sorts of operations under hypnotism. Dr. Milne Bramwell, in "Hypnotism, Its History, Practice and Theory" (London, 1906), lays down the rules for hypnosis for anesthetic purposes. They are eminently practical.

While hypnotism can be used to produce anesthesia, it has many disadvantages. The length of the hypnosis cannot always be arranged so as to a.s.sure anesthesia during the whole of an operation, while in some cases it will continue after the operation for some time in spite of every effort on the part of the hypnotist to bring the patient to himself. Besides, the depth of the hypnosis cannot always be a.s.sured, and sometimes some sensation remains. Patients will groan and wince and move, though, of course, under ether or chloroform such manifestations may take place, yet the patient afterwards will give every a.s.surance that not the slightest pain was felt. In some cases, however, even where the pain sensation is not severe during an operation under hypnosis, it may, nevertheless, prove sufficient, when continued for some time, to bring the patient out of the hypnotic state.

For short operations of minor character, undoubtedly hypnosis can be employed successfully. As we explain in the chapter on Hypnotism, anyone can produce hypnosis who has confidence in his own power and in whom the patient has trust. There is no need of a special hypnotist, and there is no special faculty required. There should be some familiarity with procedures, but any man has just as much hypnotic power as another. The influence does not pa.s.s from the operator to the subject, but is due to the subject's concentration of his attention so that there is a short circuiting of a.s.sociation tracts within the brain very probably, which does not permit the entrance into consciousness of sensations through any path except one or two, usually that of hearing, and sometimes of sight, less frequently of other sensations.

Concentration of Attention.--In a great many cases of minor operations, such as the opening of a boil of a small abscess, the pulling of a tooth, the lancing of a gum, or other such procedures, a surgeon who is confident in his own mental power over his patient can rather easily produce a state of mind in which the discomfort of the surgical procedure is greatly minimized. There are certain physical helps for this. For instance, if patients are asked to breathe rapidly and deeply for a few minutes, there is a hyperoxygenation {756} of the blood which seems to obtund sensibility. If patients are told of this, and then made to breathe rapidly for a half a minute in order that they may continue consciously their deep, rapid breathing even when pain is noted, a state of mind is produced from concentration of attention on their breathing in which painful sensations are greatly obtunded. The effect is probably more mental than physical, and is well worth while trying because of the amount of pain it often saves.

Waking Suggestion.--Without resort to hypnotism, much can be accomplished by mental suggestion in the waking state to lessen the pain of surgical operations and maneuvers. This is particularly true as regards nervous persons, who will otherwise emphasize their discomfort, and for those of lesser intelligence, children, and the like. Esdaile's experiences in India show how much can be done in this way. Often the hypnosis was so slight that the patients were perfectly cognizant of everything that went on around them, yet under the compelling influence of the a.s.surance of Dr. Esdaile, whom they trusted completely, they did not complain of pain nor wince even when considerable surgical intervention was practiced, and they always a.s.sured their friends afterwards that they had felt nothing. I know an American physician who has an almost similar power over negroes.

Ordinarily it requires more of an anesthetic to produce insensitiveness to pain in the negro than in a white person. By personal a.s.surance, by the absolute securing of their confidence, and through their trust in him, this man is able to produce anesthesia without the use of more than a minimum quant.i.ty of the anesthetic. He is able to do the same thing with children, and, of course, it is well known that mental influence over them is extremely important in limiting the amount of anesthetic that will be necessary.

Personality of Anesthetist.--Some anesthetists by their personal influence are able to bring patients under the influence of an anesthetic with much less excitement and, as a consequence, with the use of much less of the anesthetic than others. It is the same question of personal influence that extends through all medicine. Some men seem to have it naturally, and others not, though to some extent, at least, it may be cultivated. Of course, it is now well understood that, under no circ.u.mstances, should a patient be forced to take an anesthetic. This is as true for a child as for any other patient. Only a little management is required to secure the cooperation of even a young child. Above all, there must be no struggling, and while there may be a pa.s.sing stage of excitement, which cannot be entirely controlled, this can be eliminated by those who are skillful. It may be necessary, especially in the case of children, for the little patients to become familiar with the anesthetist. They should see him on several occasions and should be made to feel that they know him.

The presence of a stranger is enough of itself to excite children and make them suspicious and resentful of any manipulations. It may be well for them to have breathed through the cone on several occasions and to play a sort of game with it. In this way children will often go under an anesthetic without any struggle or excitement.

It seems a little childish to suggest similar procedures with grown patients, but even surgeons of long experience with the older methods who have insisted on the trial being made on their patients have found much benefit from it. Familiarity with the anesthetist and even with the inhaler {757} and the breathing through it on several occasions beforehand, when no anesthetic is being administered, helps many patients not a little. This preliminary is particularly of help with regard to nervous patients and especially women. It is very seldom necessary to use nitrous oxide as a preliminary to ether if this mode of procedure is practiced.

Mental Diversion.--It is well to concentrate the mind of the patient on something else besides his sensations. One element that is extremely important for anesthesia is deep breathing. The patient must then have his attention called to the necessity for deep breathing and should frequently have the suggestion to this effect repeated in his ear as he comes under the anesthetic. There should be some practice in deep breathing deliberately beforehand, with the idea of accustoming the respiratory mechanism to take deep breaths by habit even when not entirely under the control of the will. This may be done with the inhaler on a few occasions at least. The occupation of attention necessary for deep breathing during the taking of the anesthetic lessens the concentration of mind on the feelings, and actually makes the discomfort much less. Besides, deep breathing distributes the anesthetic over the lungs, leads to its absorption more rapidly, and makes the irritation of the anesthetic less by diffusing it over a larger surface. On the contrary, short, rapid breaths lead to an intensity of irritation and much slower absorption.

Skilled anesthetists have found it of decided advantage to keep the patient's mind fixed on something else besides the breathing. Perhaps the easiest recommendation is that of locking the hands over the abdomen just above the umbilicus and asking the patient to hold tight.

This gives something very definite to think about and to occupy the mind with. I have seen patients of rather nervous organizations go under the influence of even a very small quant.i.ty of an anesthetic when required to hold their hands thus and when the command was constantly repeated, "Hold your hands tight," whenever there was the slightest sign of struggle or excitement. Where this was done tactfully and regularly, I have seen patient after patient go into anaesthesia without struggle or excitement and usually without any noise or even a loud word. I realize how much the personality of the anaesthetist means in such cases, and I feel sure that anyone who is confident in his own power in the matter will produce a corresponding feeling of confidence in the patients.

Fright in Anesthesia.--There seems good reason to think that occasionally the deaths reported from anesthesia have really occurred from fright or at least have been greatly influenced by emotional factors. It has often been noted that these deaths occurred particularly at the beginning of the administration of an anesthetic and before anything like a sufficient quant.i.ty to produce a toxic effect had been administered. In other cases it has been noted that patients were allowed to come out partially from under the anesthetic, and as they recovered consciousness were disturbed by some incident.

Sometimes the pain seems to act as an inhibitory agent on the heart.

In more than one reported case the patient told afterwards of hearing very distinctly some remark that seemed to be of bad omen. In one case in my own experience the breathing and heart stopped (though the patient fortunately was resuscitated) as a consequence of hearing a series of rather loud goodbyes said at the door of the elevator leading to the operating room during the {758} course of an operation just at a moment when the anaesthetic influence was very much lessened for a while. In some cases where there has been great fear of the anesthetic which has been talked over beforehand by the patient, even a few whiffs of the ether or chloroform have given rise to serious symptoms from stoppage of the heart. It is evident that it is extremely important properly to predispose such patients.

The well-known surgical warning not to make remarks during the course of an operation that might prove disturbing to the patient, needs to be emphasized. By a very curious psychological anomaly some patients, though thoroughly anesthetic as regards pain, are able to hear and understand very well remarks that are made near them. Fortunately, such patients are few in number, but they are sometimes rather seriously disturbed by chance observations that for the moment at least seem to have an unfavorable bearing on their case. Besides, certain patients sometimes have their special senses come out from under the influence of the anesthetic before their sense of pain. They may also hear and be disturbed. These cases ill.u.s.trate very well the place of mental influence and how much deliberate attention should be given to this phase of the treatment of surgical cases coming out of anesthesia, as well as while more or less under its influence.

Local Anesthesia.--In local anesthesia it has come to be generally recognized in recent years that the personality of the operator is one of the most important factors for success. A number of local anesthetics have been introduced, and in some hands only comparatively small quant.i.ties of them are needed in order to produce complete absence of pain during operations. In other hands, however, considerable and even toxic quant.i.ties may have to be employed and sometimes without entire satisfaction. Infiltration anesthesia depends for its success largely on the personal influence of the administrator over the patient. It is extremely important that the patient should have complete confidence and not have that confidence disturbed in any way. For instance, he needs to be warned that he will feel the slight p.r.i.c.k of the needle when it is first introduced, for otherwise he will be disturbed by even so slight a pain at the very beginning and will magnify subsequent feelings until satisfactory local anesthesia becomes impossible. Without thorough command over the patient and complete trust, local anesthesia never succeeds except in very minor operations. There are some men, however, who can do even severe and extensive operations with comparatively small amounts of local anesthesia. Others cannot perform satisfactorily even minor operations with large amounts. It is the operator, his personality, and mental influence over the patient that counts.

Vomiting After Anesthesia.--The vomiting that comes after anesthesia, especially with ether, often const.i.tutes not only an annoying but sometimes a seriously disturbing complication. It must not be forgotten that vomiting in neurotic individuals, and especially women, may be largely due to a neurosis. In the section on Psychotherapy in Obstetrics we discuss the vomiting that occurs in connection with pregnancy and suggest that it is nearly always neurotic in character.

The best-known European obstetricians are now agreed in this. While ether produces a tendency to vomit in everyone, in some the actual vomiting is very slight or completely absent. If patients expect that there is to be vomiting, if they are of the neurotic temperament that not only {759} vomits easily but has a tendency to secure sympathy by fostering this symptom unconsciously perhaps, then the vomiting may become even a dangerous complication. If there is no expectancy in the matter, however, but if, on the contrary, it is made clear to these patients before the anesthetic is administered that, while there may be some nausea, there need be no vomiting unless they yield too readily to their feelings, much can be done to lessen the vomiting. A single suggestion may not mean much in this matter, but a series of suggestions properly given beforehand, especially if the patient has seen others vomiting after operations and is worrying about it, may prove of excellent contrary suggestive value.
