Combined continuous and demand narcotic dosing for patient-controlled analgesia after cesarean section.
New patient-controlled analgesia devices can deliver an analgesic by continuous infusion along with demand dosing. This prospective investigation involving postcesarean-section patients was undertaken to determine whether a combination of continuous infusion and demand dosing of meperidine would provide more effective analgesia than would demand dosing alone during the first 24 hours. During a 12-month period, 171 patients were prescribed meperidine postoperatively, using a 5- to 10-mg demand dose no more frequently than every 10 minutes. ⋯ All patients were able to understand the nurse, became ambulatory, and tolerated liquids on the first postoperative day. The infusion rate of 20 mg/h was most acceptable in requiring fewer demand doses while providing satisfactory pain relief without undesired sedation. In conclusion, a system combining continuous infusion and demand dosing was preferable to demand dosing alone, and added no apparent hazards.

Meta AnalysisSide effects and complications related to interpleural analgesia: an update.
Interpleural analgesia has been successfully used for pain relief after cholecystectomy, renal surgery, breast surgery and thoracotomy. Little has been reported about side effects and complications. ⋯ Pneumothorax was the most frequently registered complication followed by signs of systemic toxicity and pleural effusion. Horner's syndrome, pleural infections and catheter rupture have also been reported.
