Medical control of parkinsonism has resulted in a longer life expectancy and better quality of life for these patients, who are now presenting for surgical treatment of a variety of conditions. In addition to the risks associated with age, these patients are more prone to restrictive pulmonary problems. General anesthesia should be avoided when possible.
The use of Althesin for induction of anaesthesia in 57 patients showed that it is a satisfactory induction agent. However, with the exception of rapid recovery with minimal after-effects, it has no major advantages over the commonly used barbiturates.
The respiratory response to hypercapnia in dogs anaesthetized with ketamine was increased. This respiratory stimulation was most probably due to a direct effect of the drug on the medullary respiratory neurones. This effect was not modified by preanaesthetic medication pentobarbitone 5 mg/kg or morphine 0.1 mg/kg. Catecholamine response to hypercapnia was essentially the same as that reported by hypercapnic dogs anaesthetized with thiopentone.
This study reports retrospectively the post-anaesthetic complications in surgical out-patients. We have studied the incidence and severity of these complications during the first five post-operative days in 500 female patients who underwent tubal ligation by laparoscopy. The report shows that post-anaesthetic complications in surgical out-patients are frequent but of mild severity. Although they produced some discomfort for the patients most of them were of the opinion that the advantages of having the operation as out-patients made up for the discomfort.
Seventy-four patients aged 14 months to 71 years, classified as ASA I and II were anesthetised with Ethrane for surgical interventions of mean duration 117 minutes. With the exception of 5 patients who were directly anesthetised with Ethrane, the others received Ethrane after induction with Penthiobarbitone. Maintenance of anesthesia was ensured with 1 to 4p. 100 concentrations of Ethrane and 33p. 100 oxygen and 66p. 100 nitrous oxide. Tracheal intubation was facilitated by injection of 1 mg/kg of succinylcholine. Induction with enflurane is rapid with no phenomena of excitation or irritation of the ear passages. The cardiovascular apparatus is stable with no arrythmia but an increase in heart rate of 11 to 50p. 100 is noted and in 41p. 100 of the cases hypotension of 35p. 100 of the intitial value. During spontaneous ventilation, a type of rapid and superficial respiration is observed with a flow volume of 5.3 ml/kg for an average frequency of 25/min. The arterial blood gases show slight hypercapnia. Myorelaxation is significant and better than that obtained with halothane. Coming round poses few problems apart from agitation in adolescents. Response to simple orders appears at 13 minutes. Trembling and rigidity occur in 41p. 100 of the cases for 5 to 30 minutes. From the hepatic point of view, no lastin enzyme changes were noted and no renal toxicity was demonstrated. Ethrane appears to be a good anesthetic agent but the few advantages mentioned means that it does not fulfil ideal conditions.
