Randomized Controlled Trial Clinical TrialEvaluation of the efficacy of elastic compression stockings in prevention of hypotension during epidural anaesthesia for elective caesarean section.
The ability of graduated compression elastic stockings to prevent hypotension during elective epidural caesarean section was evaluated. Twenty women were randomly assigned to two groups of ten, one group being fitted with the stockings. The incidence and degree of hypotension were the same in both groups. Graduated compression elastic stockings are of no benefit in reducing the incidence of maternal hypotension during caesarean section.

Randomized Controlled Trial Comparative Study Clinical TrialContinuous infusion epidural analgesia with lidocaine: efficacy and influence during the second stage of labor.
A randomized double-blind study evaluated the analgesic efficacy and influence of maintaining a continuous epidural infusion of 0.75% lidocaine during the second stage of labor in nulliparous women. When the cervix was 8 cm or more dilated, unidentified study solution was substituted for the known 0.75% lidocaine solution and continued until delivery. The study solution for 26 patients was 0.75% lidocaine; 27 subjects received saline. ⋯ There was no difference between the groups in the duration of the second stage of labor (73 +/- 63 versus 76 +/- 48 minutes). Operative delivery frequency was similar (31 and 37%), as were umbilical cord blood acid-base values. It is concluded that maintenance of the continuous epidural infusion of 0.75% lidocaine did not prolong the second stage of labor, but it also did not significantly differ from saline in quality of second stage analgesia or frequency of perineal anesthesia.

Randomized Controlled Trial Comparative Study Clinical Trial
Effect of topical lignocaine on the sympathoadrenal responses to tracheal intubation.
The catecholamine and cardiovascular responses to laryngoscopy and tracheal intubation have been studied in 30 patients undergoing elective gynaecological surgery, allocated randomly to one of three groups: group 1 received 4% lignocaine 160 mg using a Forrester Spray; group 2 received 4% lignocaine 160 mg by "Laryng-o-jet"; group 3 received an equal volume of saline administered by Forrester Spray. In all three groups, there were similar and statistically significant increases in mean arterial pressure and plasma adrenaline and noradrenaline concentrations 1 min after intubation, with diminution of these responses by 5 min after intubation. There were no differences between the three groups at any stage, which suggests that topical anaesthesia of the mucosa of the upper airway, as performed conventionally, is ineffective as a means of ameliorating the pressor and catecholamine responses to routine laryngoscopy and intubation.

Randomized Controlled Trial Clinical Trial
Intraoperative bupivacaine during outpatient hernia repair in children: a randomized double blind trial.
Postoperative pain is a major problem following surgery in the ambulatory child. A study was undertaken to test the effect of intraoperative bupivacaine on postoperative pain in children undergoing outpatient hernia repair. Ninety-nine children aged 1 to 7 years underwent outpatient inguinal herniorrhaphy under general anesthesia. ⋯ Activity level at home on the day of surgery did not differ significantly between groups, but activity level over the following 48 hours was higher in group 1 (P less than .05). The two groups were similar with respect to all other parameters. We conclude that intraoperative bupivacaine decreases post-operative pain and analgesic use, and promotes early ambulation in children undergoing hernia repair.

Randomized Controlled Trial Comparative Study Clinical Trial
Subarachnoid analgesia for caesarean section. A double-blind comparison of plain and hyperbaric 0.5% bupivacaine.
Equal volumes (2.5 ml, 12.5 mg) of plain 0.5% bupivacaine (glucose-free) and hyperbaric 0.5% bupivacaine (in 8% glucose) were compared in a randomized double-blind study of 40 patients undergoing Caesarean section under subarachnoid anaesthesia. There were no differences in the rate of onset, maximum spread, number of patients with high cervical levels, duration of anaesthesia or incidence of post-spinal headaches between the two solutions. ⋯ Thirteen patients in the hyperbaric group and 10 in the isobaric group required i.v. ephedrine to treat hypotension. Nine patients (23%) developed a post-spinal headache, and three were treated with an extradural blood patch.
