Randomized Controlled Trial Comparative Study Clinical Trial
Pre-emptive analgesia: comparison of preoperative with postoperative caudal block on postoperative pain in children.
We have compared in 25 children the effect of preoperative with postoperative caudal block on pain after circumcision in a double-blind, randomized study. After induction of anaesthesia, patients were allocated randomly to receive a caudal block either before (n = 14) or immediately after (n = 11) surgery. Postoperative pain was rated on a paediatric pain scale. ⋯ Using the Mann-Whitney U test (significance < or = 0.05) there was no significant difference in cumulative postoperative analgesic requirements within the first 48 h and in times to first analgesic administration between the groups. Cumulative pain score, assessed every 30 min for the first 8 h after operation, was significantly lower for those patients who received caudal anaesthesia after operation. Thus we could not demonstrate any advantage in performing caudal block before compared with after surgery.

Clinical investigation into the incidence of direct damage to the lingual nerve caused by local anaesthesia.
The aim of this study was to investigate the amount of damage to the lingual nerve by mandibular block anaesthesia alone. For this purpose the records of 12,104 patients in whom mandibular block anaesthesia was administered without any type of surgery were reviewed. ⋯ In 17 out of these 18 patients the tongue sensation recovered after a period of 6 months. Only in one patient (0.008%) was there a slight sensory diminution of the tongue, even after one year.

A combination of the lumbar plexus and sciatic nerve blocks using 2-chloroprocaine (2-CP) for unilateral lower extremity anaesthesia was studied. The purpose of this work was to evaluate the efficacy of 2-CP for ambulatory surgery of short duration with this combination of blocks. Twenty-five patients ASA 1 and 2 were studied. ⋯ The mean duration of the sensory block was 88.7 +/- 20.9 min, 83.3 +/- 16.4, 79.7 +/- 17.8 min and 93.7 +/- 22 min for the sciatic, femoral, obturator and lateral femoral cutaneous nerves respectively. Success rate was 92% and no major complication occurred. We conclude that a combination of the lumbar plexus and the sciatic nerve blocks with 2-CP is a useful technique for ambulatory surgery of short duration.

Post-circumcision analgesia: comparison of topical analgesia with dorsal nerve block using the midline and lateral approaches.
Forty-five patients undergoing circumcision were allocated randomly to one of three study groups to compare topical analgesia with dorsal nerve block using the midline or lateral approach. Pain scores, side effects and analgesic requirements were recorded after surgery. ⋯ Fentanyl requirements and pain scores were similar in patients who received a dorsal nerve block using either the midline or lateral approach. The incidence of side effects after surgery was similar in all three groups.
