Correction of tetralogy of Fallot during infancy usually eliminates the risks associated with general anaesthesia. In rare cases of uncorrected defects persisting into adulthood, anaesthetic management during non-cardiac surgery may therefore be challenging. We describe the use of continuous spinal anaesthesia to successfully circumvent the operative risk of major abdominal surgery in an adult patient with uncorrected tetralogy of Fallot.

The intraoperative effects of continuous spinal anaesthesia, and the efficacy of postoperative continuous spinal analgesia in 48 elderly high risk patients undergoing major abdominal, vascular or orthopaedic surgery is reported. Intraoperative anaesthetic technique proved to be safe and provided satisfactory results in the immediate postoperative period. Furthermore, the postoperative analgesic regimen which involved intrathecal fentanyl and bupivacaine, and intravenous tenoxicam, provided effective analgesia for all patients. The intrathecal analgesic regimen was administered continuously through a PCA pump which had the facility to provide bolus doses when requested in predetermined lockout intervals. The mean doses of fentanyl and bupivacaine infused intrathecally for the first 24 h postoperatively were 14.5±1.5 μg h−1 (mean±SD) and 0.72±0.08mg h−1 (mean±SD), respectively, while the requirements for analgesia decreased progressively over time but lasted for 118 h. The technique provided effective analgesia with low pain scores that was reflected by the ease in performing physical exercises and the pleasant co-operation with the physiotherapist. Only minor complications related to anaesthesia/analgesia were encountered.

The intra-operative management of two patients with chronic obstructive pulmonary disease and cardiovascular pathology, who underwent peripheral reconstructive vascular surgery under continuous spinal anaesthesia, is described. Furthermore, continuous intrathecal analgesia was also continued in the post-operative period and provided effective pain relief that was reflected by the favourable surgical outcome.

Both continuous spinal anaesthesia and continuous epidural anaesthesia are supposed to provide adequate post-operative pain relief. The purpose of this randomized, prospective study was to compare the quality of analgesia, occurence of side effects and patient satisfaction between spinal and epidural administration of bupivacaine during the first post-operative 72 h. One hundred and two patients scheduled for hip arthroplasty were randomly assigned to one of two groups: Group 1 received continuous spinal anaesthesia for intra-operative and post-operative management, Group 2 received continuous epidural anaesthesia. Immediately after surgery, the continuous spinal anaesthesia-group received a 1-mL bolus (bupivacaine 0.25%), followed by a continuous infusion of 10 mL over 24 h. The continuous epidural anaesthesia-group received a 10-mL bolus (bupivacaine 0.25%), followed by 2mL h−1. The level of pain was gauged from a verbal rating score and from a visual analogue scale; the degree of motor blockade was recorded using the Bromage score. In the continuous spinal anaesthesia-group 90.2% reported complete analgesia on the verbal rating scale, but only 21.6% of the continous epidural anaesthesia-group did. The visual analogue scale scores given by the continuous spinal anaesthesia-group were significantly lower than those of the continuous epidural anaesthesia-group. The percentage of patients with a motor block was significantly higher in the continuous spinal anaesthesia-group on the day of surgery and at the first post-operative day. During the first 24 h,nausea and vomiting occured more often in the continuous epidural anaesthesia-group. The satisfaction was considered excellent in 92.2% of the continuous spinal anaesthesia-group and in 70.6% of the continuous epidural anaesthesia-group. It is concluded that continuous spinal anaesthesia and continuous epidural anaesthesia are effective and safe for post-operative pain relief after hip replacement. Compared with continuous epidural anaesthesia, continuous spinal anaesthesia provides faster onset of pain relief,ensures better analgesia and results in more satisfied patients.
