Randomized Controlled Trial Comparative Study Clinical TrialPatient-controlled epidural analgesia following caesarean delivery: a comparison of pethidine and fentanyl.
Pethidine and fentanyl have both been used to provide patient-controlled epidural analgesia (PCEA) following caesarean delivery. Both have been compared with epidural morphine but these drugs have not been compared with each other. Patient-controlled epidural analgesia was used in a prospective, randomized, double-blind, cross-over trial to compare fentanyl and pethidine for postoperative epidural analgesia in women having elective caesarean deliveries. ⋯ Results from 45 patients showed no difference in pain level outcomes, but pethidine scored better in all side-effects except for drowsiness at 48 hours. Patients were more satisfied with pethidine (P = 0.015) and overall 65% of patients preferred pethidine. We conclude that pethidine is a suitable drug for patient-controlled epidural analgesia and leads to greater patient satisfaction than does fentanyl.

Randomized Controlled Trial Comparative Study Clinical TrialAnalgesia for acute musculoskeletal trauma: low-dose subcutaneous infusion of ketamine.
Low-dose ketamine by subcutaneous infusion (0.1 mg/kg/h) was compared in double-blind fashion with intermittent morphine (0.1 mg/kg intravenously, four-hourly) as analgesic regimen in 40 ASA-I adults after acute musculoskeletal trauma. Pain was assessed using visual analogue scales and sedation was graded on a four point rank drowsiness score. Objective cardiovascular and respiratory parameters and patient acceptability in terms of supplementary analgesia and early mobilization were also recorded. ⋯ None of the patients in ketamine group required supplementary analgesia (P < 0.001) and the patients could be easily mobilized for traction/splintage as compared with patients in the control group (P < 0.001). The incidence of nausea and vomiting in the morphine group was high (P < 0.01). The study shows that subcutaneous infusion of ketamine provides safe and effective analgesia in acute musculoskeletal trauma.
