The complications arising in association with the administration of general anaesthetics to 2658 inpatients for oral surgical procedures from 1978 to 1982 and to 999 outpatients from 1977 to 1981 are reported. In the two series of patients complications occurred with overall incidences of 17.2 and 25.1 per cent respectively. In the inpatient group the incidence of complications rose with age, with an increase in the surgical risk factor, and occurred with different frequencies according to the anaesthetic regime used. ⋯ Sedation methods in outpatients were almost free of complications. Most of the complications occurred during emergence from anaesthesia and in the early postoperative period. Nearly all patients receiving insufflation anaesthesia returned home on the same day but about three-quarters of those being intubated remained in hospital overnight.

Randomized Controlled Trial Comparative Study Clinical Trial
Nausea and vomiting in day-case dental anaesthesia. The use of low-dose droperidol.
The anti-emetic effects of low-dose droperidol (1.25 mg), ultra-low-dose droperidol (0.25 mg) and a placebo were compared in patients admitted for day-case dental anaesthesia. Ultra-low-dose droperidol produced a significant decrease in the subjective feeling of nausea without delaying recovery or discharge from the hospital (p less than 0.05). Low-dose droperidol did not significantly reduce nausea (p greater than 0.05) and prolonged the recovery time (p less than 0.05).

Review
Opioid analgesics in anesthesia: with special reference to their use in cardiovascular anesthesia.
In this article, an attempt has been made to review the use of receptor stimulating pure agonist opioids in anesthesia, especially in patients with cardiovascular disease. Particular emphasis has been placed on the use of opioids in high doses to produce anesthesia, techniques that recently have become popular in cardiovascular anesthesia. A major benefit of opioid anesthesia is the cardiovascular stability obtained during induction and throughout operation, even in patients with severely impaired cardiac function. ⋯ The use of very large doses of opioids also will prolong postoperative respiratory depression. High doses of opioids can reduce or prevent the hormonal and metabolic responses to the stress of surgery. However, even very large doses of fentanyl or its newer analogues do not prevent marked increases in plasma catecholamine concentrations in response to cardiopulmonary bypass.(ABSTRACT TRUNCATED AT 400 WORDS)

A case is presented of a patient who required anaesthesia for the removal of an inhaled silver tracheostomy tube. The anaesthetic problems are discussed. Regular inspection of silver tracheostomy tubes is recommended.
