Clinical Efficacy of Clonidine versus Fentanyl as Spinal Adjuvant to 0.5% Hyperbaric Bupivacaine for Knee Arthroscopy under Subarachnoid Block- A Comparative Evaluation
نویسندگان
چکیده
Subarachnoid block is commonly used regional anesthetic technique for patients who require surgical anesthesia for lower extremities, perineum, pelvic girdle or lower abdomen. It may be useful in patients with difficult airway or suffered from co-morbidities of severe respiratory disease. Spinal anesthesia covering the mid-thoracic level yields a contracted small intestine to provide superior surgical conditions in combination with profound muscle relaxation of abdominal muscles.

Dexmedetomidine Versus Fentanyl as Adjuvants to Intrathecal Bupivacaine in Knee Arthroscopy. A Randomized Controlled Trial
Introduction: Knee arthroscopy can be safely performed with neuraxial anaesthesia. Many adjuvants were added to local anesthetics to prolong the duration of the block. The earliest adjuvants were opioids followed by the α2 agonist clonidine. Dexmedetomidine is a newly introduced α2 agonist with promising characteristics in this respect. Methods: 30 patients were included in the study devided in...
متن کاملComparison of intrathecal clonidine and fentanyl in hyperbaric bupivacaine for spinal anesthesia and postoperative analgesia in patients undergoing lower abdominal surgeries
BACKGROUND There are many adjuvant used along with bupivacaine for subarachnoid block, but fentanyl and clonidine are commonly used as adjuvant to intrathecal bupivacaine for prolonging both sensory and motor blockade as well as postoperative analgesia in patients undergoing lower abdominal surgeries. OBJECTIVE There is a paucity of studies comparing the efficacy of fentanyl and clonidine as ...

Background: Among all the spinal adjuvants, clonidine, an alpha-2 agonist has the ability to alleviate both the somatic and visceral pain and is more potent at spinal site, favoring its neuraxial administration. Objective: This study was done to compare the onset and duration of sensory and motor blocks, duration of analgesia, haemodynamic and adverse effects of Clonidine, buprenorhine and fent...

Objectives: Intrathecal fentanyl and clonidine are effective analgesics with different mechanisms of action. This study compares 25 μg of both these drugs given intrathecally regarding onset, quality, and duration of hyperbaric bupivacaine-induced spinal block and side effects. Methods: A total of 90 patients of ASA I and II were randomly allocated into three equal groups. Group A received 0.5 ...

Background: Intrathecal adjuvants to local anaesthetic enhance the quality and duration of spinal anaesthesia. The present study was aimed to comparatively evaluate the clonidine and butorphanol as adjuvants to intrathecal hyperbaric bupivacaine for subarachnoid blockade during orthopaedic surgeries. Patients and method: Sixty four adult consented patients of both gender of ASA physical status ...
