Comparative Study
Postoperative analgesia for day-case herniorrhaphy patients. A comparison of cryoanalgesia, paravertebral blockade and oral analgesia.
Patients were admitted as day-cases for inguinal herniorrhaphy under epidural anaesthesia and chlormethiazole sedation. The patients were given oral analgesia, and in addition, some were given either a paravertebral block with a dextran/bupivacaine mixture or cryoanalgesia of the ilio-inguinal nerve for postoperative pain relief. These anaesthetic and analgesic techniques are discussed in relation to day-case herniorrhaphy.

One hundred patients undergoing thoracotomy had their intercostal nerves blocked by cryoanalgesia before closure and the effect of this on their postoperative pain was evaluated. Of the 100 patients, 79 were free of pain, 12 had some discomfort, and nine reported severe pain necessitating narcotic analgesia (mean 1.5 injections per patient). ⋯ Overall, lack of pain and greater alertness much enhanced the value of physiotherapy, which resulted in a low incidence of complications and a smooth recovery. The technique of cryoanalgesia is simple, extremely effective, and apparently offers benefits not conferred by other methods of preventing pain after thoracotomy.

Epidural morphine was evaluated for the control of postoperative pain after cesarean section (CS). Sixty-five patients undergoing elective CS with epidural bupivacaine were studied. Of these, 40 were given a single dose of 4 mg of morphine through an epidural catheter on termination of surgery. ⋯ The epidural morphine was associated with a prolonged period of postoperative analgesia and a greatly reduced total papaveretum requirement for the 48 h (30.9 mg for the study group in contrast to 67.6 mg for the controls). The difference between the two groups was significant (P less than 0.001). We concluded that epidural morphine is an efficient method for the control of postoperative pain following CS, a single dose of 4 mg providing relief from pain for 8 to 12 h and sometimes longer.

Randomized Controlled Trial Comparative Study Clinical TrialEpidural morphine for postoperative pain relief.
Thirty-three patients were randomly assigned to two groups to study the analgesic potency, duration of action and side effects of epidural and intramuscular morphine after hip surgery. Two milligrams of preservative-free morphine chloride in 10 ml of normal saline in the epidural space was compared to 10 mg of intramuscularly administered morphine. There was a more rapid onset of action after intramuscular morphine. ⋯ Nausea and/or vomiting was less common after epidural morphine (20% versus 55%). Pruritus or respiratory depression which have been reported previously were not encountered. However, it is recommended that preservative-free solution are used to avoid itching and that the patients are monitored, as respiratory depression may occur long after administration of epidural opiate.
