Neuraxial blocks result in sympathetic block, sensory analgesia and motor block. Continuous epidural anesthesia through a catheter offers several options for perioperative analgesia. Local anesthetic boluses or infusions can provide profound analgesia. Although the role of low-dose ketamine (<2 mg/kg intramuscular, <1 mg/kg intravenous [IV] or ≤ 20 μg/kg/min by IV infusion) in the treatment of post-operative pain is controversial, perioperative administration of a small dose of ketamine may be valuable to a multimodal analgesic regimen. A local anesthetic can be used for wound infiltration intra-operative to minimized the surgical pain. ⋯ Thoracic epidural analgesia had better control on hemodynamic changes intra-and postoperatively than ketamine infusion with local wound infiltration in open cholecystectomy.

Hypothermia is a frequent observation in elderly males undergoing transurethral resection of prostate (TURP) under spinal anesthesia. The use of irrigating fluids at room temperature results in a decrease body temperature. Warmed irrigating solutions have shown to reduce heat loss and the resultant shivering. Such investigation was not much tried in low resource settings. ⋯ Use of warm irrigation fluid during TURP reduces the risk of perioperative hypothermia and shivering.

It is known that, unilateral thoracic paravertebral block (TPVB) applications performed with general anesthesia provide satisfactory conditions for open cholecystectomy increase the quality of post-operative analgesia and patient comfort and decrease the frequency of post-operative nausea and vomiting. In this case report, the TPVB was presented which was performed for two patients with high risk of anesthesia who have been planned to undergo open cholecystectomy.

Anesthetists used lower doses of fentanyl, successfully with hemodynamic control by titrating volatile anesthetic agents or vasodilators for fast-tracking in cardiac surgery. ⋯ The I-gel airway is well-tolerated by adult patients undergoing cardiac surgery, and requires lower total doses of anesthetics than endotracheal intubation with hemodynamic control and helps in fast-tracking.

For optimum magnetic resonance imaging (MRI) image quality and to ensure precise diagnosis, patients have to remain motionless. We studied the effects of intranasal dexmedetomidine and ketamine with intravenous midazolam for pre-procedural and procedural sedation in school aged children. ⋯ Intranasal dexmedetomidine 3 μg kg(-1) or ketamine 7 mg kg(-1) can be used safely and effectively to induce a state of moderate conscious sedation and to facilitate parents' separation and IV cannulation. Addition of midazolam in a dose not sufficient alone to produce the target sedation achieved our goal of deep level of sedation suitable for MRI procedure.
