Caudal epidural block for analgesia following herniorrhaphy with laparoscopy in children.
This study prospectively evaluated the efficacy of caudal epidural block in providing analgesia following inguinal herniorrhaphy and laparoscopy. Laparoscopy was used only to inspect the contralateral side to determine if a second hernia was present. No surgical manipulation was performed through the telescope. ⋯ Six of 8 patients required a single dose of intravenous fentanyl (0.5 microgram/kg) to maintain scores of 2 or less. No significant complications related to caudal epidural block were noted in any patient. Caudal epidural block provides effective analgesia following inguinal herniorrhaphy and laparoscopy in children.

Comparative Study
The effects of sevoflurane are similar to those of isoflurane on the neuromuscular block produced by vecuronium.
We have examined the interactions of 1 MAC of isoflurane and sevoflurane (and 66% nitrous oxide in oxygen) with vecuronium, using the EMG response of the abductor digiti minimi to train-of-four (TOF) stimulation of the ulnar nerve. We constructed dose-response curves for vecuronium in 54 patients. ⋯ The rate of recovery of T4:T1 was significantly greater when both anaesthetics were discontinued. However, this rate was similar for both anaesthetics, suggesting that the mechanism of action of the two anaesthetics is similar.

Randomized Controlled Trial Comparative Study Clinical TrialPostoperative analgesia after major shoulder surgery with interscalene brachial plexus blockade: etidocaine versus bupivacaine.
Postoperative pain is commonly treated with significant doses of narcotics, occasionally resulting in side effects including nausea, pruritus, and respiratory depression. One potential advantage of regional anesthesia is profound postoperative analgesia that reduces exposure to potent narcotics. To evaluate the efficacy of two long-acting local anesthetics, bupivacaine and etidocaine, in providing pain relief after major shoulder surgery, we randomized 20 patients to receive either bupivacaine or etidocaine for brachial plexus block as the primary anesthetic for shoulder surgery. ⋯ Bupivacaine, however, possesses significant cardiotoxicity and has a relatively delayed onset in peripheral neural blockade. Etidocaine is less cardiotoxic and also has a more rapid onset of effect. Thus etidocaine may be a preferable agent for interscalene block for major shoulder surgery.
