Despite widespread use of a parenterally administered mixture of meperidine, promethazine, and chlorpromazine (Demerol, Phenergan, and Thorazine, DPT), there has been no systematic evaluation of its efficacy and complications in emergency department patients. We reviewed the medical records of all patients less than 16 years old who received DPT in our ED during the 24-month period ending December 31, 1987. Of 487 patients who received DPT, the maximum dose was 50/25/25 mg, respectively. ⋯ An abnormal initial mental status examination or an underlying neurologic abnormality was significantly associated with complications (P less than .05). DPT appears to be a safe and relatively effective sedative for selected pediatric ED patients when administered as a ratio of 2:1:1 mg/kg, respectively. Complications are increased in patients with acute or underlying neurologic abnormalities.

A transdermal formulation of fentanyl (TTS-fentanyl, Alza Corp., Palo Alto, CA) was evaluated in 13 surgical patients after an abdominal operation. An intraoperative dose of fentanyl (100-200 micrograms i.v.) was administered at the same time as the TTS-fentanyl systems (50-125 micrograms/h) were applied to the antero-lateral chest wall. The TTS-fentanyl systems remained in situ for 24 h and were then removed and a second lot of systems were applied to the contra-lateral chest wall. ⋯ These effects were due to the combined effects of a sustained blood fentanyl concentration and the intermittent supplementary pethidine doses. Side effects due to the topical formulation were transient and included erythema (8 patients) and a minor rash (2 patients) in the area occluded by the systems. The TTS-fentanyl systems provided a significant contribution to postoperative pain control but, at the TTS dose rates used, supplementary doses of pethidine were required by all patients probably to control 'incident' pain.

Randomized Controlled Trial Clinical Trial
Epidural diamorphine and bupivacaine in labour.
A double-blind randomised study was performed to assess the analgesic effect of epidural diamorphine, administered with bupivacaine, on primigravid women in labour. Fifty patients received 0.25% bupivacaine 10 ml via the epidural catheter as their initial dose; patients in Group 1 received diamorphine 5 mg with the bupivacaine. A 0.1% bupivacaine infusion was started at 10 minutes and bolus doses of bupivacaine were given if required. There was a significant reduction in rate of bupivacaine administration, pain scores at 20 and 30 minutes, number of supplements required, and degree of motor blockade in the diamorphine group.

Case ReportsEpidural analgesia in the management of symptomatic symphysis pubis diastasis.
The pain of symphysis pubis diastasis during and after pregnancy can be disabling. This report describes for the first time the successful use of epidural analgesia in relieving the pain of this disorder. ⋯ The epidural analgesia described allowed her to mobilize immediately and remain normally active for the remainder of her pregnancy. Early consultation with an anesthesiologist in severe cases of symphysis pubis diastasis is encouraged.

Fifty patients undergoing cholecystectomy either electively or urgently were treated in the postoperative period with the intrapleural injection of 30 mL of 0.75% bupivacaine hydrochloride with epinephrine (1:200,000). The frequency of narcotic administration and the postoperative stay were compared with those of 50 historical controls. ⋯ There were no complications related to catheter insertion or bupivacaine toxic effects. This technique is safe and effective in controlling perioperative pain.
