INTRODUCTION Postoperative period after panhysterectomy is very painful as there is too much tissue handling. In the practice of regional anesthesia neuraxial, opioids have been used extensively as an adjuvant to bupivacaine to enhance the potency and duration of sensory and motor block produced by bupivacaine with satisfactory results. However, delayed respiratory depression by opioids has pro...

OBJECTIVE Our goal was to demonstrate which position would be hemodynamically and technically better by comparing the effects of combined spinal epidural (CSE) in the sitting or lateral decubitus position for elective cesarean deliveries on maternal and neonatal parameters and ephedrine requirement. METHODS Sixty parturients were randomly assigned into two groups to perform CSE in the sitting...

An increase in the concentration of bupivacaine from 0.5% to 0.75% and etidocaine from 1.0% to 1.5% for extradural block resulted in a more rapid onset of sensory analgesia and motor blockade, a greater frequency of adequate analgesia,a greater depth of motor block and a longer duration of sensory analgesia and motor blockade. An increase in the concentration of prilocaine from 2% to 3% failed ...

Objective: In order to prolong the duration of intrathecal lidocaine, various drugs are used along with it. Due to the promising effects of tizanidine on central nervous system, it can be assumed that tizanidine can have a positive effect on increasing the anesthesia duration too. Thus, we aimed to investigate the effect of oral tizanidine on the duration of lidocaine spinal anesthesia.Me...

BACKGROUND Addicted patients have innate tolerance to local anesthetics in both neuraxial and peripheral blocks. Dexmedetomidine (Dex) is a highly selective α2 adrenergic receptor agonist used as additive to increase quality and duration of peripheral nerve blocks. OBJECTIVES The current study aimed to compare the effect of dexmedetomidine and fentanyl additives on bupivacaine to prolong the ...

conclusions the findings showed that adding sufentanil or midazolam to bupivacaine shortens the onset of spinal anesthesia and increases the time duration of anesthesia; however it does not change the motor block recovery time. adding sufentanil delays the first request for narcotic analgesics while adding midazolam leads to a decrease in nausea and hypotension. adding sufentanil or midazolam d...

Background Dexamethasone as an adjuvant to bupivacaine and ropivacaine for supraclavicular brachial plexus (SCBP) block prolongs motor and sensory blockade. However, comparison of effect of dexamethasone (8 mg) when added to these two local anesthetics has not been well studied. This study was conducted to compare analgesic efficacy of dexamethasone as adjuvant to bupivacaine and ropivacaine in...
