Randomized Controlled Trial Comparative Study Clinical Trial
Intrathecal meperidine for elective caesarean section: a comparison with lidocaine.
The purpose of this study was to determine the efficacy of intrathecal meperidine in patients undergoing Caesarean section, and also to compare meperidine with heavy lidocaine. Fifty full-term pregnant women, ASA physical status I or II, presenting for elective Caesarean section under spinal anaesthesia were randomly divided into two groups with 25 in each, to receive either intrathecal meperidine or lidocaine. All patients received premedication with oral ranitidine, 150 mg, the night before surgery, and again two hours before surgery. ⋯ All the newborns in both groups cried immediately after birth and had an Apgar score > 7. The mean duration of postoperative analgesia was six hours in the meperidine group and one hour in the lidocaine group (P < 0.01). Postoperative analgesia requirement was less in the meperidine than in the lidocaine group (P < 0.01).(ABSTRACT TRUNCATED AT 250 WORDS)

Randomized Controlled Trial Comparative Study Clinical Trial
A comparison of two doses of epidural fentanyl during caesarean section.
A prospective, randomized, double-blind study was performed to compare the analgesic efficacy and side effects of epidural fentanyl, 25 micrograms vs 50 micrograms, when used to supplement epidural anaesthesia for elective Caesarean section. Fifty ASA I and II patients were randomized into two groups: Group I (n = 24) received 25 micrograms and Group II (n = 26) received 50 micrograms of epidural fentanyl after the epidural test dose. No differences between the two groups were found on any measures of intraoperative pain, nausea, drowsiness, respiratory depression, hypotension, pruritus and neonatal outcome. The low levels of pain experienced by patients indicates that doses higher than 50 micrograms of epidural fentanyl are usually unnecessary for optimal analgesia.

Randomized Controlled Trial Comparative Study Clinical TrialCervical epidural steroid injection for cervicobrachialgia.
Fifty patients with chronic resistant cervicobrachialgia were randomly divided into two groups. Twenty-five patients (group A) were treated with cervical epidural steroid/lidocaine injections and 17 patients (group B) were treated with steroid/lidocaine injections into the posterior neck muscles. Another eight patients from group B were excluded from the study because they had started the process of litigation of insurance claims and their subjective analysis of pain relief might therefore not be trustworthy. ⋯ These differences were statistically significant. We failed to achieve significant improvement of tendon reflexes or of sensory loss in both groups, but the increase in the range of motion, the fraction of patients who were able to decrease their daily dose of analgesics, and recovery of the capacity for work were significantly better in group A. We encountered no complications in either group of patients.(ABSTRACT TRUNCATED AT 250 WORDS)
