Postoperative analgesia with epidurally injected buprenorphine and its side effects were investigated in 100 patients who had received lower abdominal surgery. All patients received initially 8 ml of bupivacaine and 0.1 mg of buprenorphine. ⋯ No significant difference in the incidence of side-effect was found among groups C, D, E. We conclude that a dose of a approximately 15 micrograms.h-1 might be optimal for postoperative pain relief after lower abdominal surgery.

Randomized Controlled Trial Comparative Study Clinical TrialEpidural anesthesia for labor in an ambulatory patient.
The effectiveness of two epidural analgesic regimens on the ability to ambulate was compared in women in labor by a prospective, randomized, double-blind design. One group of patients received epidural fentanyl, a 75-micrograms bolus and an infusion of fentanyl 2.5 micrograms/mL at 15 mL/h (FENT, n = 53). A second group received ultra low-dose bupivacaine (0.04%), epinephrine (1.7 micrograms/mL), and fentanyl (1.7 micrograms/mL) (BEF, n = 77), a 15-mL bolus followed by an infusion at 15 mL/h. ⋯ Neither problem occurred in FENT patients. Neonatal outcome was similar in both groups. Approximately 70% of women receiving epidural analgesia with fentanyl or ultra low-dose bupivacaine, epinephrine, and fentanyl may ambulate safely during labor.

Randomized Controlled Trial Comparative Study Clinical Trial
Comparison of 0.125% bupivacaine with 0.125% bupivacaine and clonidine as extradural analgesia in the first stage of labour.
We have studied 42 healthy parturients with singleton vertex pregnancies, who were in the first stage of labour and requesting extradural analgesia. They were allocated randomly in a double-blind fashion to receive either 0.125% bupivacaine plain or 0.125% bupivacaine with clonidine 120 micrograms. Efficacy of analgesia was evaluated using linear visual analogue scoring (VAS), sensory block was assessed using bilateral pinprick in the mid-clavicular line and sedation scored on a five-point scale. ⋯ Maternal heart rate was less than baseline values at 30-90 min in the bupivacaine-clonidine group only. Sedation was greater in the bupivacaine-clonidine group, especially from 15 to 45 min (P < 0.01). There were no differences in fetal heart rate, mode of delivery or Apgar scores between the two groups.

Intrathecal infusional analgesia for nonmalignant pain: analgesic efficacy of intrathecal opioid with or without bupivacaine.
We report on the analgesic efficacy of intrathecal infusions of opioids alone or in combination with bupivacaine in 16 nonmalignant pain patients with implanted pumps. Three patients had nociceptive pain, five had neuropathic pain, and 8 had mixed pain syndromes. Infusional therapy was delivered over a combined monthly total of 445 mo of therapy (mean, 27.8 mo). ⋯ Thirteen patients (81%) reported good to excellent results with opioid alone or opioid combined with bupivacaine. The addition of bupivacaine improved analgesia in two of three patients with nociceptive pain (66.7%), compared to eight of ten patients with a pure or mixed neuropathic component to their pain (80%). We conclude that intrathecal opioids alone or in combination with bupivacaine are efficacious for the treatment of nonmalignant pain states and are relatively free of significant side effects or tolerance.

Randomized Controlled Trial Comparative Study Clinical TrialThoracic versus lumbar administration of epidural morphine for postoperative analgesia after thoracotomy.
The purpose of this study was to compare the effects of thoracic and lumbar epidural morphine on pulmonary function and analgesia after thoracotomy for pulmonary resection. ⋯ The authors conclude that thoracic epidural morphine administration in patients after thoracotomy results in decreased morphine requirements and the same degree of analgesia as does lumbar administration.
