[Giant subcutaneous emphysema, pneumothorax and pneumomediastinum occurring in a 4-month-old infant recovering from anesthesia following surgery of a cleft palate].

The authors mention the case of pneumomediastinum and major cervico-facial-thoracic subcutaneous emphysema in a 4 month baby recovering from early surgery for a cleft palate, caused by a barotrauma (positive, pressure ventilation). After an emergency draining of the two pneumothorax, the situation evolved quickly, favourably and with no after effects whatsoever. They insist on the necessity of a rapid diagnosis concerning this rare complication (which can quickly evolve dramatically) and on the importance of pediatric anesthesia facilities.

[Caudal block in the surgical repair of vesico-renal reflux].

One hundred and twenty children have benefited from surgical cure for vesico-renal reflux under loco-regional anesthesia per caudal way, with use of a mixed solution of Lidocaine 1%, Bupivacaine 0.5%, with Adrenaline, along with a complementary narcosis. During the per operative time: the subsequent analgesia and muscular relief have always been excellent and lasted long enough. The hemodynamic status always showed a perfect stability. As to the ventilation, no deleterious effect could be demonstrated. Per operative blooding is reduced and central temperature is more easily controlled. During the post-operative time: the caudal anesthesia has allowed to maintain an efficient analgesia during a mean period of 12 hours which has been considered as sufficient. All the children went quickly back to a normal digestive function. There was no complication relevant to this technique.

[Post-transfusion thrombopenia treated with gammaglobulins].

Thrombopenia and a haemorrhagic syndrome occurring on the eighth postoperative day were probably related to a post-transfusion purpura, confirmed by the discovery of antiplatelet antibodies not belonging to the PLA1 antigen system. The stabilization of this haemorrhage and a full recovery were obtained by giving high doses of intravenous human gammaglobulins. Blood replacement only rarely induces postoperative immuno-allergologic thrombopenia; heparin is the best known causative agent. It is concluded that platelets should never be given so long as the responsible agent is not formally identified.

[Effects of enflurane and halothane on hepatic function in biliary surgery].

The effects of two volatile anaesthetics on hepatic function are compared in 80 patients in hepato-biliary surgery. 40 patients were anaesthetized either with enflurane or halothane. This study is based on the variations of blood levels of gamma GT, bilirubin, SGOT SGPT, alkaline phosphatase, L.D.H. Samples were taken the day prior to the operation, one, two and five days afterwards. The results show an increase in the levels of BD, SGPT, LDH no 5, less important with enflurane than with halothane, and mainly in patients with preoperative hepatic abnormalities. Enflurane appears to be preferable in such cases.

[Electro-anaesthesia during neuro-surgery (author's transl)].

The authors have performed 66 (cranial or spinal) operations with electro-anaesthesia supplemented by neuroleptics and pancuronium. In this technique, which respects the necessities of neurosurgical anaesthesia, analgesia is produced by means of Limoge's rectified high frequency currents. The protocol consists of: induction by a neuroleptic, application of the electrical current, intubation with benzodiazepin and succicurarium, controlled ventilation with a 50 p. cent oxygen/50 p. cent nitrous oxyd mixture and curare as required. The efficiency was estimated according to the necessity of a supplementary drug analgesia (fentanyl). The use of fentanyl, i.e. drug intoxication, was strongly reduced in 90 p. cent of the cases (average 0,46 micrograms/kg/hour). Absolute failures were encountered in 3 cases only. Patients waked up in very good conditions and extubation occurred on an average of 16 minutes. Reflexes of cough an deglutition are not depressed by electro-anaesthesia and we think this preservation of the respiratory function to be very profitable for such neurosurgical patients. Our opinion by now is that the best indications for electro-anaesthesia are high-risk patients, with a special mention for surgery of the posterior fossa.

[Pediatric ECG monitoring. 2,500 pediatric patients under anaesthesia (author's transl)].

The authors report 98 cases of cardiac arrhythmia observed in the course of 2,500 pediatric anesthesias performed with constant electrocardiographic monitoring. The patients, aged 0 to 18 years, were in most cases healthy. Anesthesia was performed by different techniques for both surgical and non-surgical interventions for a variety of conditions, both serious and routine. Other than 3 cases of cardiac arrest (1 death) cardiac arrhythmias usually followed a benign course without hemodynamic repercussions. The authors emphasize the value of early detection of cardiac arrhythmias as well as vigorous treatment of predisposing conditions such as inadequate ventilation, acidosis and pain. The absence of correlation between the degree of rick, as estimated preoperatively (related to patient or procedure risk factors), and the frequency of occurrence seems to point to the value of more widespread use of ECG monitoring of pediatric patients undergoing anesthesia.
