Background and Aims This service evaluation project assesses patient satisfaction with home analgesia following a single-shot sciatic popliteal nerve block versus combined single-shot sciatic popliteal nerve block and perineural catheter technique with local anaesthetic infusion continued at home via an elastomeric pump for up to 48 hours post hospital discharge. Both nerve block techniques were initiated preoperatively for ambulatory ankle replacement surgery.

Methods Retrospective data on the nerve block technique and patient satisfaction were collected from anaesthetic charts and follow-up home calls for patients who underwent ambulatory ankle replacement between April 2022-December 2022. Thirty patients, 15 who received a single-shot block (group A) and 15 who received a combined single-shot block and perineural catheter technique with local anaesthetic infusion continued at home via an elastomeric pump (group B), were included in this service evaluation. The following responses were collected from patients via follow-up home calls: 1. What is the level of satisfaction with your pain control up to one week after hospital discharge (not satisfied, satisfied, very satisfied)?

2. Would you be happy to receive the same nerve block technique if you were to have the operation again?

Results Patient satisfaction with the block technique is summarised in the table 1 below.

Conclusions Patients who received a combined single-shot block and perineural catheter technique reported better satisfaction with home analgesia than with a single-shot block.
