The cellular and synaptic mechanisms that underpin the state of general anaesthesia are discussed. Anaesthetics act principally on synaptic processes and this provides a satisfactory basis for understanding their effects on neural networks. ⋯ Effects on action potential firing patterns also play a role in anaesthetic modulation of neuronal signalling. Many of these complex data can be explained in terms of altered ion channel function.

Randomized Controlled Trial Comparative Study Clinical TrialPostoperative apnea, bradycardia, and oxygen desaturation in formerly premature infants: prospective comparison of spinal and general anesthesia.
Eighteen formerly premature infants scheduled for inguinal herniorrhaphy and who were less than 51 wk postconceptional age were assigned to either the general anesthesia group (GA: atropine, halothane, and nitrous oxide) or the spinal anesthesia group (SA: hyperbaric tetracaine). Twelve-hour, three-channel continuous recordings of respiratory rate (chest wall impedance), electrocardiogram (ECG), and hemoglobin O2 saturation (SpO2) were obtained preoperatively and after surgery. ⋯ There were no differences in the incidence of postoperative central apnea. We conclude that spinal anesthesia reduces postoperative hemoglobin oxygen desaturation and bradycardia in formerly premature infants undergoing inguinal herniorrhaphy.

Comparative Study Clinical TrialA retrospective comparison of interscalene block and general anesthesia for ambulatory surgery shoulder arthroscopy.
An increasing percentage of all surgery is performed in an ambulatory surgery setting. Concurrently, arthroscopy of the shoulder joint has allowed definitive repair of shoulder pathology to occur in this environment. This study was designed to ascertain whether interscalene block is reliable and efficient for use in same-day surgery compared with general anesthesia for shoulder arthroscopy. ⋯ Interscalene block should be considered as a viable alternative to general anesthesia for shoulder arthroscopy in ambulatory surgery patients.

The Swiss Society of Anaesthesia and Resuscitation describes anesthesia as an activity of physicians, and a continuous presence of a medical anaesthesist is required. In small regional hospitals in the alpine region it is impossible to compete with big hospitals in the central area of Switzerland and there is no possibility to afford an anaesthesist for 365 days a year and 24 hours a day. ⋯ The education and the control of this person has to be performed by a medical anaesthesist. This is the only way in keeping the high quality of medical support in the peripheral region specially in the alpine part of our country.
