Abstract
There are comprehensive findings on the immediate recovery of patients from different types of anaesthesia, but more information is needed on how patients manage at home after ambulatory surgery. One hundred and seventy-three elective knee arthroscopy patients were randomised into four different anaesthesia groups to receive either spinal anaesthesia (SA) with 5% lidocaine or general anaesthesia (GA) with propofol infusion, isoflurane inhalation or desflurane inhalation. The patients were interviewed over the phone on the next day and asked to complete a questionnaire after 1 week. One hundred and sixty-eight patients (97%) were reached by phone. The questionnaire was returned by 163 patients (94%). After 24 h, all the patients were satisfied with the type of anaesthesia they had received, but 2% of the SA patients would have chosen GA and 4.3% of the GA patients would have chosen SA for the next operation. Based on the questionnaires returned after 1 week, 8.3% of the SA patients would have wanted to have GA, and 4.7% of the GA patients would have wanted to have SA in the future. The incidence of nausea (4.2%) and vomiting (1.8%) was very low in the whole series, with no differences between the anaesthesia groups. Headache after 24 h was experienced by 15.7% of the SA and 10.3% of the GA patients. After 1 week, SA patients reported headache upon standing in 13.5% of the cases, backache in 36.5% and lower leg pain in 59.6%. The corresponding figures for GA patients were 4.5, 9.9 and 39.6% ( P<0.05). In spite of the good immediate recovery profile in the all anaesthesia groups, the fact that SA patients reported a higher incidence of headache, backache and lower leg pain after 1 week may be signs of post spinal headache and transient neurologic symptoms (TNS). For overall patient comfort, GA might be a better anaesthetic choice in ambulatory surgery.
