    AbstractThis study was done to assess the efficacy of a perineural catheter for pain relief following carpal tunnel release (CTR). Sixty-six patients undergoing open CTR under local anaesthesia (LA) were randomly divided into three groups: Groups A and B had a perineural catheter and Group C served as non-blinded control group. Postoperative pain relief was by self-administration of either ropivacaine (Group A) or saline (Group B) via an elastometric pump and by oral paracetamol in Group C. Patients in Group A had a significantly greater difference in summed pain intensity than Group B. Fewer patients in Group A requested supplementary analgesics than in Group C. Patient satisfaction was higher in Group A than in Group B on day 1. However better analgesia was not associated with better functional recovery.
