Case ReportsRemifentanil infusion prolongs spinal anesthesia.
Spinal anesthesia was given to a patient undergoing transurethral resection ofprostate (TURP). A total of 3.2 ml of bupivacaine 0.5% mixed with fentanyl 20 mcg were used. The patient started experiencing sensation after 150 min. Remifentanil intravenous infusion prolonged the duration of anesthesia for an additional 105 minutes.

Randomized Controlled Trial Comparative StudyComparison of three methods of preventing rocuronium induced pain on injection using venous occlusion technique: a randomized prospective double blind controlled study.
Intravenous administration of rocuronium bromide causes pain at the site of injection in most patients. The mechanism that leads to this side effect is still unknown and multiple drugs' pretreatments were used to prevent its occurrence with varying success rates. ⋯ Remifentanyl is a better choice of opioid in preventing pain on rocuronium injection using venous occlusion technique than fentanyl, with efficacy comparable to Xylocaine.

Randomized Controlled TrialSpinal anaesthesia for pelvic surgery: low concentrations of lignocaine and bupivacaine are effective with less adverse events.
The aim of this study was to compare the clinical efficacy of 5% lignocaine, 2.5% lignocaine, 0.5% bupivacaine and 0.25% bupivacaine in subarachnoid block for pelvic surgeries. ⋯ [corrected] For subarachnoid block for pelvic surgeries longer than two hours 0.25% bupivacaine is a better choice as compared to 0.5% bupivacaine. However for short duration surgeries lasting up to one hour, 2.5% lignocaine is a better choice as compared to 5% lignocaine as the lower concentrated solutions of bupivacaine and lignocaine are more haemodynamically stable compared to their higher concentrations and with similar duration of ensory and motor block.
