Role of nebulised dexmedetomidine, midazolam or ketamine as premedication in preschool children undergoing general anaesthesia-A prospective, double-blind, randomised study.

Background And Aims: Preschool age children are psycho-biologically vulnerable to all surgical procedures. In this study, we investigated the effect of nebulised dexmedetomidine, midazolam and ketamine as sedative premedication for alleviating parental separation anxiety, facilitating face mask acceptance and reducing emergence agitation in paediatric patients undergoing general anaesthesia.

Methods: A prospective, randomised, double-blind study was done involving 96 children of age 3-7 years, randomly allocated into three equal groups and pre-medicated with either nebulised dexmedetomidine 2 mg/kg (GroupD), midazolam 0.

Unilateral versus bilateral spinal anaesthesia in geriatric patients undergoing hemiarthroplasty: a comparative study.

Introduction: Conventional bilateral spinal anaesthesia can produce haemodynamic alterations that can be detrimental to geriatric patients. Unilateral spinal anaesthesia produces predominant blockade on the operated side, thereby reducing the incidence of hypotension. There is a scarcity of comparative studies evaluating the effects of unilateral spinal anaesthesia in the elderly population.

Incidence of postoperative nausea and vomiting following gynecological laparoscopy: A comparison of standard anesthetic technique and propofol infusion.

Objective: To determine the safety, efficacy, and feasibility of propofol-based anesthesia in gynecological laparoscopies in reducing incidences of postoperative nausea and vomiting compared to a standard anesthesia using thiopentone/isoflurane.

Design: Randomized single-blind (for anesthesia techniques used) and double-blind (for postoperative assessment) controlled trial.

Setting: Operation theater, postanesthesia recovery room, teaching hospital.

Dexmedetomidine an adjuvant to levobupivacaine in supraclavicular brachial plexus block: a randomized double blind prospective study.

Background: Apha-2 agonists are combined with local anesthetics to extend the duration of regional anesthesia. We evaluated the effect of combining dexmedetomidine with levobupivacine with respect to duration of motor and sensory block and duration of analgesia.

Methods: Sixty patients scheduled for elective forearm and hand surgery were divided into two equal groups in a randomized double blind fashion.
