Patients suffering from muscle disorders have an elevated anesthetic risk, i.e. to develop malignant hyperthermia or rhabdomyolysis. In addition serious cardial and pulmonal complications are imminent during anesthesia for surgery. ⋯ 83% of the patients showed pathologic ECG, 26% cardiac insufficiency in echocardiography, 31% pathologic X-rays of the thorax and 73% serious pulmonary restriction. Consequently avoiding of anesthetic agents with a high trigger potential for developing malignant hyperthermia (i.e. halothane or muscle relaxants type succinylcholine) prevented severest complications as malignant hyperthermia, rhabdomyolysis or cardiac arrest. Nevertheless other complications (i.e. arrhythmia, cardiac insufficiency) occurred due to the cardiac and pulmonary limitations more pronounced in the older patients of the spine surgery group.

Although most anaesthetic textbooks cite dental injury as a complication of endotracheal intubation few studies have examined the extent and nature of the problem. Such damage however, formed the basis for one-third of all confirmed or potential anaesthetic claims notified to the Medical Protection Society between 1977 and 1986. This article seeks to explore the extent of the problem, outline predisposing factors, summarise current prophylactic measures and make recommendations to reduce the overall incidence. ⋯ Where he/she considers there to be a higher than average risk of dental damage occurring during intubation a more specialised examination should be conducted by a dental surgeon. It may, where appropriate, be possible for remedial dental treatment to be carried out and customised mouth guards to be constructed prior to the operation. Obviously such recommendations have certain financial implications and would have to be subject to controlled cost-benefit analysis before their widespread application.

The aim of this study was to assess whether passive smoking affected the frequency of airway complications in children undergoing general anaesthesia. One hundred and twenty-five children undergoing general anaesthesia for elective daycase surgery were monitored for adverse respiratory events and desaturation during induction, intra-operatively and in the recovery room. Oxygen saturation was monitored throughout and a venous sample was taken for estimation of carboxyhaemoglobin levels. ⋯ This was related to the cumulative number of cigarettes smoked by individuals to whom the child was exposed (p < 0.05). Neither carboxyhaemoglobin levels nor domiciliary address were predictive of desaturation. This study suggests that passive smoking contributes to postoperative arterial oxygen desaturation following general anaesthesia in children.

Case-1: A 72-year-old woman with no past neurological history was scheduled for a rectum resection under general combined with epidural anesthesia. An epidural catheter was introduced at T11-12 interspace without any difficulties. During the operation, she had hypotensive episode needing dopamine, but waked up from anesthesia without any event. ⋯ The MRI examination two weeks after the operation showed degeneration below middle thoracic spinal cord. His neurologic symptoms have not improved for two years. The etiology of neurologic deficits of these two case is not obvious although the relation between epidural anesthesia and neurologic symptoms was most likely.
