Effect of Locally Administered Dexmedetomidine as Adjuvant to Levobupivacaine in Supraclavicular Brachial Plexus Block: Double-blind Controlled Study.

Context: Brachial plexus block is effective with good postoperative analgesia in upper limb surgery has gained importance as it safe, low cost, and maintains stable hemodynamics intraoperatively. To decrease the onset time and prolong the duration of nerve block bicarbonate, opioids (morphine, fentanyl, etc.), sympathomimetic agents (epinephrine, phenylephrine, etc.

A rare case of recurrence of primary spinal neurocysticercosis mimicking an arachnoid cyst.

Neurocysticercosis (NCC) is a common parasitic infection of the central nervous system but isolated primary spinal NCC is of very rare occurrence. The authors report a case of 44-year-old male, a postoperative case of multiple spinal NCC lesion excision 2 years ago, who presented with cauda equina syndrome and magnetic resonance imaging revealed a lesion mimicking an arachnoid cyst in the D1-9 region of the spinal cord. On intraoperative surgical exposure multiple cysts were found and excised.

Palonosetron and palonosetron plus dexamethasone to prevent postoperative nausea and vomiting in patients undergoing laparoscopic cholecystectomy: A prospective, randomized, double-blind comparative study.

Background: Laparoscopic cholecystectomy (LC) is associated with a high risk of postoperative nausea and vomiting (PONV). Palonosetron is a newer 5HT3 receptor antagonist, which is routinely used in our institution to prevent PONV in patients scheduled for LC, under general anesthesia (GA). We formulated this study to find out whether the palonosetron and dexamethasone combination will be a better choice than palonosetron alone in the prevention of PONV.
