Randomized Controlled Trial Clinical TrialEpidural morphine for the relief of postoperative pain after cesarean delivery.
To determine the safety, efficacy, and dose response of epidurally administered morphine for analgesia after cesarean delivery, 40 healthy women who underwent cesarean delivery with epidural anesthesia were randomly assigned to receive one of four regimens for relief of postoperative pain: intramuscular administration of morphine, 7.5 mg (N = 10); or epidural administration of morphine, 2 mg (N = 10), 5 mg (N = 10), or 7.5 mg (N = 10). Evaluations were made of intensity and relief of pain, time to administration of additional analgesic medications, changes in vital signs and blood-gas tensions, and adverse effects. Intramuscular administration of 7.5 mg of morphine effectively relieved pain for only a short time. ⋯ There were no significant changes in vital signs or blood-gas tensions. Side effects included pruritus and nausea, which occurred frequently but were usually mild and easily treated. We concluded that either 5 mg or 7.5 mg of morphine epidurally administered was effective and safe in providing prolonged analgesia after cesarean delivery.

Opiates such as morphine have a direct spinal effect, acting at special receptor sites in the dorsal horn. When morphine is administered epidurally, it diffuses to the cord substance, producing analgesia of improved quality after a dose of 2 to 4 mg. ⋯ Significant side effects are uncommon, but pronounced respiratory depression can occur late and careful observation is necessary. The first instance of paraplegia in association with epidural morphine anesthesia has been reported herein.

Continuous intercostal nerve blockade was used to provide analgesia after cholecystectomy. The blockade was maintained by the insertion of a single extradural catheter into an appropriate intercostal space and by "topping-up" with local anaesthetic on demand. ⋯ A mean improvement of 37% on pre- "top-up" peak flows, was found. It is suggested that continuous intercostal analgesia is a a safe, reliable and powerful form of analgesia which may improve respiratory function after cholecystectomy.
