Anaesthetic-related recovery room complications.

A prospective survey was conducted over a one-month period in all surgical patients admitted to the recovery room of a university-affiliated teaching hospital. Complications arising in the recovery room were documented by the nursing staff according to predefined criteria and were critically evaluated. A total of 443 patients were admitted to the recovery room and in 133 (30%) of these, some form of complication was noted. There were 86 patients with complications referable to the central nervous system, 68 with abnormal cardiovascular parameters, 24 with nausea and/or vomiting and 10 with abnormalities referable to the respiratory system. Many patients had more than one complication. The results are discussed, with emphasis on their relevance to current anaesthetic practice. It is concluded that many patients exhibit recovery room complications when they are specifically sought. The recovery period remains a time of great potential danger to patients.
