There is conflicting information in the literature regarding nerve damage following regional anesthesia. Intraneural injection of local anesthetic was described as a safe practice in regional anesthesia. This review focuses on the histopathological and functional assessment of peripheral nerve function following intraneural injection of local anesthetics.

Procedural sedation and analgesia is widely being used for female laparoscopic sterilization using combinations of different drugs at varying doses. This study compared the combination of fentanyl and propofol, and ketamine and propofol in patients undergoing outpatient laparoscopic tubal ligation, with respect to their hemodynamic effects, postoperative recovery characteristics, duration of hospital stay, adverse effects, and patient comfort and acceptability. ⋯ As compared to ketamine-propofol, fentanyl-propofol combination is associated with faster recovery, earlier discharge, and better patient acceptability.

Ropivacaine, a long-acting local anesthetic agent, has been used for postoperative analgesia in brachial plexus block (BPB) at high doses. However, use of lower doses would reduce the occurrence of adverse effects. ⋯ Our results suggest that low-dose ropivacaine is clinically acceptable for BPB under general anesthesia.

Myasthenia gravis (MG) is an autoimmune disease with an incidence of 2-10/100,000 cases per year, characterized by muscle weakness secondary to destruction of postsynaptic acetylcholine receptors. In these patients, important perioperative issues remain unresolved, namely, optimal administration of cholinesterase inhibitors, risks of regional anesthesia, and prediction of need of postoperative mechanical ventilation. We describe the use of a low-dose spinal anesthesia in a patient with MG who was submitted for emergence exploratory laparotomy. The utilization of low-dose spinal anesthesia allowed us to perform surgery with no adverse respiratory or cardiovascular events in this patient.

Clinically optimized focusing of drug administration to specific need of patient with bispectral index (BIS) monitoring results in reduced dose and faster recovery of consciousness. This study was planned with an aim to study and compare the conventional clinical end point or BIS on the requirement of dosage of propofol, hemodynamic effects, and BIS alterations following propofol induction. ⋯ No significant difference in the induction dose of propofol was observed when assessed clinically (loss of verbal response) or by BIS monitoring. Traditional teaching to titrate the dose of propofol and depth of anesthesia during intubation by loss of verbal response is as good as BIS value monitoring.
