Six cases of grave hypothermias are reported, having arisen during surgical interventions which necessitated a rapid and abundant transfusion of badly warmed blood. The role of favouring factors, surrounding cold due to the air-conditioning, anaesthesia, extent of the area of operation, seems important. The symptomatology permits the individualization of a hypothermic syndrom neighbouring the picture described in toxic accidental hypothermias. Accidents during the warming process associate collapse and disturbances in coagulation. It is therefore necessary to consider certain signs of alarm as important and generalize the conditions for prevention of thermolysis in the operating theatre.

Pneumothorax during operation is always clinically serious. The symptoms are usually sudden cyanosis, accompanied by cardio-vascular collapse and difficulty or even impossibility to ventilate owing to increased pressures of insufflation. Immediate or secondary bilateral pneumothorax is relatively common, then may appear associated complications such as subcutaneous emphysema or pneumo-mediastinum. Early diagnosis is necessary to apply simple treatment and avoid a course which may be rapidly fatal. The authors report 3 cases of pneumothorax during anesthesia and consider the clinical forms, the mechanisms and causes of this accident.

The notion of anaphylactic shock under anaesthesia implies sensitization, with a minimum delay of 1 week, on the occasion either of a previous anaesthesia with the responsible product, or with taking a drug with common antigenic determinants. Clinically this is reflected by the rapid and explosive appearance of symptoms which are always comparable: tendency to vascular collapse, respiratory bronchospastic distress, erythematous rash and Quincke's edema, gastrointestinal disorders, etc. These signs and symptoms of anaphylactic shock are closely related to the pharmacological actions of substances liberated during the reaction, of reaginic orgin (histamine, S.R.S.A.). It is reproduced by the direct effects of numerous anaesthetics on the liberation of theses very substances without the intermediary of an immunological mechanism. In consequence, the clinical argument alone is not sufficient to assert the true anaphylactic nature of a shock. Consequently, the elements of the history must be strongly borne in mind: notion ofsensitization during a previous anaesthesia, to the responsible product or to a drug which could have a crossed antigenicity with it.

Eighteen grave anaphylactic accidents arising during induction or during anaesthesia, are analysed. By order of frequency, the clinical signs are cutaneous manifestations (70 p. 100 of the cases), bronchospasm (65 p. 100), cardiovascular collapse (45 p. 100). In four cases, cardiac arrest occurred. The course was always favourable, with no after-effects. Immuno-allergic tests enabled one to make the diagnosis of true anaphylaxis in eight cases (seven shocks due to succinylcholine, one due to propanidide), of non specific histamine-liberation in five cases; in the other cases, it was impossible to express an opinion.

Between 1975 and 1978, 35,000 to 40,000 Dutch men underwent sterilization operations per year. Sterilization is not indicated if the man is not married, has no children, if there are marital or mental problems, or if there are indications for contraception or sterilization for his wife. Vas ligation, vasotomy, and vasectomy are three operations to induce male sterility. Vasectomy is the most effective but least likely to be reversible. The operation can be performed in a polyclinic under local anesthesia and takes 15-30 minutes. The operation procedure is described in detail. The first sperm count should be taken 8 weeks after the operation. In most cases, azoospermia is demonstrated after 3 months following the operation. Complications of vasectomy which occur during the operation are vasovagal collapse (1-5%) and motor disturbance (2-10%). Early post-operative complications include: intrascrotal hematoma (2-7%), infection (1-6%), and pain (1-10%). Frequent late complications are sperm granuloma (1-18%), recanalization (0-6%), and development of sperm antibodies (50-62%). Restoration of fertility after a vasectomy is usually not possible. The best results are obtained with end-to-end reanastomosis with a splint to facilitate healing.

Patients, particularly older ones, with internal medical diseases, may be hazards for the dental treatment. Therefore, anamnestic data seem to be most important in order to uncover the hazard patient (diabetes, survived heart attacks, anticoagulation, rheumatic heart affections, hypertonics, allergies). Local anesthesia can be another problem, because it may lead to collapse (psychogenous or from anaphylactic shock). Focal infection, although in general overrated in its importance for the general organism, may pose some problems before heart surgery and antibiotic therapy previously may seem necessary. Finally, therapeutic consequences from emergencies in the dental office are reviewed.

71 patients undergo myocardial revascularisation for Prinzmetal's angina; among them, 50 p. cent are operated upon in emergency according to three ways of anaesthesia: neuroleptanalgesia, analgesic anaesthesia, combined anaesthesia. The authors lay stress on the importance of per- and post-operative complications: electrocardiographic ischemia in 22 p. cent of the cases, severe ventricular excitability perturbations were observed in 21 p. cent, myocardial necrosis in 14 p. cent, cardiovascular collapse in 21 p. cent and hypertensions in 22 p cent. These complications are often associated. In the discussion, the authors underline anesthetic induction as a cause of Prinzmetal's angina in 50 p. cent of the cases. They put the accent on the severity of peroperative crisis followed in 50 p. cent of the cases by serious ventricular excitability perturbations. In 25 p. cent of the cases myocardial necrosis is a complication of the spasm of a coronary artery. In this field, posterior necrosis are more frequent and correspond to the spasm of the right coronary artery. All the patients of this series, except one, develop necrosis in the spastic area (by-passed or not). Per-operative hypertension has no incidence on the occurrence of post-operative complications. Lastly, continuous per-operative infusions of nitroglycerine has been performed in several patients in order to reduce morbidity of this type of surgery.

An eight-year-old male Yorkshire terrier which had had a cough for two years was presented and a diagnosis of tracheal collapse was made after examination with a bronchoscope. It was decided to try to correct the tracheal defect by plication. Two weeks after the operation the dog was examined under general anaesthesia. Although traction had exposed a part of the thoracic trachea it was not sufficient in this case to achieve a complete repair. In view of a grave prognosis, the dog was destroyed.

Ninety patients (age range 49--99 yr) with a fracture of the neck of the femur were anaesthetized by a technique using halothane in oxygen in a closed circuit, halothane and 66% nitrous oxide in oxygen in a Magill circuit or artificial ventilation with 66% nitrous oxide in oxygen ("IPPV group"). In all three groups, there was a small decrease in PaO2 from an overall mean of 9.07 kPa before operation to 8.13 kPa at 60 min after anaesthesia. There was no significant difference between the groups in respect of the decrease; it was concluded that closed-circuit halothane in oxygen anaesthesia for this type of surgery was not accompanied by a significant degree of absorption collapse.
