The optimal anesthetic technique for peripheral vascular surgery remains controversial. The purpose of this study was to evaluate the effect of spinal versus general anesthesia on postoperative pain, analgesic requirements and postoperative comfort in patients undergoing peripheral vascular surgery. A total of 40 patients scheduled for peripheral vascular surgery were randomly assigned to two g...

Clonidine has anti-hypertensive properties and augments the effects of anaesthesia, hence we considered it to be an ideal agent to contain the stress response to pneumoperitoneum. We studied the clinical efficacy of oral clonidine premedication in patients undergoing laparoscopic cholecystectomies. Fifty patients scheduled for elective laparoscopic cholecystectomy under general anaesthesia were...

SUMMARY To improve postoperative pain management, several concepts have been developed, including preemptive analgesia, preventive analgesia, and multimodal analgesia. This article will discuss the role of these concepts in improving perioperative pain management. Preemptive analgesia refers to the administration of an analgesic treatment before the surgical insult or tissue injury. Several ran...

STUDY DESIGN A randomized prospective study. PURPOSE To assess postoperative analgesic requirements after Phyback therapy preemptively in patients undergoing lumbar stabilization. OVERVIEW OF LITERATURE Frequency Rhythmic Electrical Modulation System is the latest method of preemptive analgesia. METHODS Forty patients were divided into two groups. Patients who were to receive tramadol wer...

Agonists acting at alpha2 adrenergic and opioid receptors have analgesic properties and act synergistically when co-administered in the spinal cord; this synergy may also contribute to the potency and efficacy of spinally administered morphine. The lack of subtype-selective pharmacological agents has previously impeded the definition of the adrenergic receptor subtype(s) mediating these effects...

Background Fentanyl is often used instead of morphine for the treatment of pain because it has fewer side effects. The metabolism of morphine by glucuronidation is known to be influenced by polymorphisms of the UGT2B7 gene. Some metabolic products of fentanyl are reportedly metabolized by glucuronate conjugation. The genes that are involved in the metabolic pathway of fentanyl may also influenc...
