Background
Post-operative pain management following laparoscopic bariatric surgery can be challenging. There are concerns regarding the use of opioids. The rate of cardiorespiratory problems following neuraxial opioids is unclear. There is little published data on their use in bariatric surgery. This study aimed to assess technique feasibility, pain outcomes, patient acceptability, and the side effects and complications of a ‘high-dose’ (1.0 mg) intrathecal diamorphine technique for patients undergoing primary laparoscopic bariatric surgery.
Materials and Methods
Fifty patients were included. Eleven patients (22%) had a diagnosis of OSA. All patients had a spinal anaesthetic with 2.0 mL of 0.25% isobaric bupivacaine containing 1.0 mg diamorphine. General anaesthesia followed together with multi-modal analgesia and anti-emesis. Post-operative pain scores, complications, and side effects in the first 24 h post-operative period were documented. Patients were followed up 6 to 8 weeks after discharge.
Results
All patients had a working spinal anaesthetic with thirty-nine insertions (78%) on the first attempt. Pain scores were similar to previously published data where they were found to be superior to a non-spinal analgesic regime. The median 24 h post-operative oral morphine equivalent consumption was 5 mg. Eight patients (16%) required urinary catheterisation. Four patients (8%) complained of pruritus. Eighteen patients (36%) had post-operative nausea or vomiting. Thirty-three patients (66%) responded to the follow-up request. Thirty of the thirty-three patients (91%) stated they would have the spinal anaesthetic again.
Conclusion
We have demonstrated that neuraxial blockade is a simple, practical, and feasible technique to adopt. Our case series demonstrated a high level of patient acceptability.
