A Comparative Study of Intrathecal Bupivacaine and Bupivacaine with Different Doses of Clonidine in Lower Limb Surgeries.

Background: Intrathecal clonidine is a very safe, nonopioid adjuvant to local anesthetics to prolong the duration of analgesia without any major side effects.

Objective: The purpose of the present study was to evaluate the efficacy of clonidine in two different doses as an adjuvant to bupivacaine intrathecally in lower limb surgeries.

Materials And Methods: A total of 75 adult patients scheduled to undergo lower limb surgeries were randomly allocated into either of three groups of 25 patients.

Comparative evaluation of different doses of intrathecal neostigmine as an adjuvant to bupivacaine for postoperative analgesia.

Objective: To study the efficacy and safety of intrathecal neostigmine at dose of 50 μg and 150 μg as an adjuvant to bupivacaine for postoperative analgesia under spinal anesthesia.

Materials And Methods: 75 patients of either sex, belonging to American Society of Anesthesiologists (ASA) physical status I and II in the age group of 30-65 years scheduled to undergo lower abdominal and lower limb surgeries were allocated randomly into 3 groups of 25 each. Spinal anesthesia was administered in Group I (control group) with 12.

Comparsion of Intravenous Lignocaine, Tramadol and Keterolac for Attenuation of Propofol Injection Pain.

Introduction: Propofol possesses many characteristics of an ideal intravenous anaesthetic agent, providing a smooth induction and a rapid recovery. However, it has been reported to evoke considerable pain on injection in 10-100% of patients. The cause of pain upon intravenous injection of propofol remains a mystery.
