Randomized Controlled Trial Comparative Study Clinical Trial[Comparative repercussions of general and spinal anesthesia on the psychological functions of the aged subject].
Although worsening cerebral function in the elderly is often said to be due to anaesthesia, it still remains to be proved that anesthesia acts on an elderly patient's psychological make-up. This study aimed to compare the psychological effects of general or spinal anaesthesia on 35 patients more than 70-yr old under repair of a subcapital femoral fracture, after having excluded 63 patients. They were randomly divided into two groups, the first receiving a spinal anaesthetic with 1.5 mg.kg-1 prilocaine (RA; n = 19), and the others a general anaesthetic with 5 mg.kg-1 thiopentone, dextromoramide, nitrous oxide and enflurane (GA; n = 16). ⋯ Individual psychological scores did not differ either. In the RA group, the postoperative tests were even better carried out than before surgery (p less than 0.05). It could therefore be concluded that anaesthesia alone has little impact on the psychological status of elderly patients.

General anaesthesia in pregnancy is still responsible for a significant morbidity and mortality. The most common and most serious complications are respiratory secondary to changes induced by pregnancy. These are dominated by hypoxia during difficult intubation and inhalation of gastric contents. Their incidence could be largely reduced by the extensive use of regional local anaesthesia.

[Development of anesthetic technics for resection-anastomosis of the trachea].
A series is reported of 109 patients, 45 +/- 18 yr old, undergoing tracheal sleeve resection. 101 patients had iatrogenic tracheal stenosis, 5 tracheal cylindroma, 2 tracheal cancer and 1 tracheal trauma. 84 patients underwent preoperative laser coagulation to increase the airway internal diameter. Anaesthesia for the sleeve resection was induced by thiopentone, and maintained by an opiate, nitrous oxide and, if necessary, a volatile anesthetic. Patients were intubated, after having been given a muscle relaxant, with either a normal length and diameter tube with a low pressure cuff, or a narrow (internal diameter less than 6 mm) 50 cm long tube with or without a low pressure cuff. ⋯ Preoperative photocoagulation reduced the risk of induction and intubation; the choice of endotracheal tube no longer depended on the tracheal diameter, but on the method of ventilation chosen. However, HFJV has tended to be phased out, except for the surgery of lesions close to the carena; it has been replaced by intermittent positive pressure ventilation via long tubes. Because laser photocoagulation can completely cure small stenoses, these patients requiring surgery were those with long stenoses which were difficult to treat.(ABSTRACT TRUNCATED AT 250 WORDS)
