INTRODUCTIONPhantom limb sensations (PLS), phantom limb pain (PLP) and stump pain (SP) are well-recognised postamputation phenomena. However, there is a dearth of related epidemiological data in Asian populations. This study was conducted to fill the information gap.

METHODSTelephone interviews were conducted with patients who underwent lower limb amputations at a tertiary hospital in Singapore. Information was obtained on phantom limb characteristics, perioperative pain and functional assessment.

RESULTSA total of 159 patients underwent amputations over a 31-month period. At the time of the interview, 47 patients had died and 66 were contactable, of whom 49 patients were interviewed. Of these, 31 (63%) patients experienced PLS. 22 patients had postoperative pain, with 9 having both PLP and SP, 3 having PLP alone and 10 having SP alone. Among the 12 patients with PLP, at least 6 (50%) experienced constant or daily pain and 7 (58%) scored their pain as moderate-to-severe. Among those with PLP and/or SP (n = 22), 5 were distressed by the pain, 11 were on analgesics and 3 received medical follow-up. 7 (32%) patients reported functional limitations secondary to PLP or SP. Altogether, 28 (57%) patients were wheelchair or bed bound.

CONCLUSIONThe incidence of PLP was 25% in our cohort. Although this is lower than that reported in other studies, it remains significant, as some patients suffered moderate-to-severe pain. The difference in incidence may be due to differences in the ethnic composition and/or indications for amputation in our group. Follow-up and care could improve the outcomes in these patients.

INTRODUCTIONThere is strong evidence that epidural analgesia provides good postoperative pain relief in adults, but its use in infants is less established. In this retrospective study, we present our experience with managing infant epidural analgesia for abdominal surgeries in a tertiary paediatric institution.

METHODSThe records of 54 infants who had received a thoracic or lumbar epidural as perioperative analgesia for abdominal surgeries were included. The mean age of the infants was 6.1 (standard deviation [SD] 3.8) months and their mean weight was 6.8 kg (SD 1.8). Most (63%) had an ASA (American Society of Anesthesiologists) status of 2 and all underwent elective gastrointestinal, urogenital, hepatobiliary or retroperitoneal surgeries. 20 catheters (37.0%) were inserted in the thoracic region and 33 (61.1%) in the lumbar region.

RESULTSA total of 52 (96.3%) catheters provided adequate intraoperative analgesia and 36 (66.7%) provided effective analgesia for the postoperative period. Active management of epidural analgesia, such as through epidural top-ups and infusion rate adjustment, was necessary to optimise analgesia in 22 (44%) of the 50 patients postoperatively. Reasons for premature catheter removal were mainly technical issues such as catheter disconnection, leakage and blockage.

CONCLUSIONOur data suggests that in experienced hands, specialised settings and active management, the success rate of epidural analgesia in infants undergoing major abdominal surgeries is high and without major incident.
