چکیده
In contrast EVE with local anaesthetic causes leaks from epidural space to subarachnoid puncture and also perineural or transdural spread of the extradural solution to enhance intensity and block duration besides volume effect. 5-7 In this study, we aimed to evaluate the efficacy of epidural volume extension (EVE) with colloid on dose requirement of intrathecal bupivacaine with fentanyl to ABSTRACT

Effect of epidural volume extension on dose requirement of intrathecal hyperbaric bupivacaine at Caesarean section.
BACKGROUND The technique of epidural volume extension (EVE) involves the injection of saline into the extradural space immediately following the intrathecal injection, as part of a combined spinal-epidural (CSE) anaesthetic. One of the suggested benefits of EVE is a reduction in local anaesthetic required. The aim of this study was to test this hypothesis by comparing the median effective doses...
متن کاملComparison of Epidural Clonidine and Dexmedetomidine for Perioperative Analgesia in Combined Spinal Epidural Anesthesia with Intrathecal Levobupivacaine: A Randomized Controlled Double-blind Study
BACKGROUND Epidural administrations of α2 agonists are being used as adjuvants as they lead to anxiolysis, sedation, analgesia, and hypnosis. AIM This study aims to evaluate the analgesic effects of epidural α2 agonists-dexmedetomidine and clonidine in conjunction with intrathecal levobupivacaine in combined spinal epidural anesthesia (CSEA). METHODS A prospective, randomized controlled stu...
متن کاملComparison of preemptive effect of intravenous ketorolac versus meperidine on postoperative shivering and pain in patients undergoing cesarean section under spinal anesthesia: A prospective, randomized, double-blind study
Background: Pain and shivering are two unpleasant problems in postoperative period. Various techniques are used to alleviate the postoperative shivering and pain. We compared the preemptive prescription of a single dose of intravenous meperidine and ketorolac on postoperative pain and shivering in patients undergoing cesarean section with spinal anesthesia. Methods: One hundred and ...
متن کاملA prospective randomized trial of lidocaine 30 mg versus 45 mg for epidural test dose for intrathecal injection in the obstetric population.
BACKGROUND The epidural test dose, used to identify unintended intrathecal placement, should reliably produce a spinal block without posing a threat to the patient. Most anesthesiologists administer a dose of local anesthetic, commonly lidocaine 45 mg. Pregnant patients are more sensitive to local anesthetics; high and total spinal anesthesia have been reported in the pregnant population with t...
متن کاملHyperbaric spinal anesthesia with ropivacaine coadministered with sufentanil for cesarean delivery: a dose-response study.
Adjuvant sufentanil could achieve effective spinal anesthesia with low dose of hyperbaric ropivacaine for cesarean delivery. Two previous studies had calculated the 50% effective dose (ED50) of intrathecal ropivacaine coadministered with sufentanil for cesarean delivery. However, the 95% effective dose (ED95) of intrathecal hyperbaric ropivacaine coadministered with sufentanil for cesarean deli...
