Background and aims: Hyperbaric prilocaine is a short-acting local anaesthetic. The aim of this study is to compare the characteristics of subarachnoid block using hyperbaric prilocaine with that of bupivacaine in outpatients undergoing transurethral resection of bladder (T.U.R.B.). Methods: In this prospective randomized controlled trial, 60 patients undergoing endoscopic urological surgery re...

Pain management is crucially important in the postoperative period as it increases patient comfort and satisfaction. The primary outcome of present study was to evaluate the effect of sufentanil added to hyperbaric bupivacaine solution 0.25% in transversus abdominis plane (TAP) block, on postoperative analgesic consumption. Fifty ASA physical status I-II term primiparous single-tone pregnant wo...

Background: Spinal anaesthesia is the most preferred regional technique as it easy to perform,economical and produces rapid onset of complete muscle relaxation. The aim intrathecal localanaesthetic provide adequate sensory motor block necessary for all infra umbilical surgeries.Aims Objectives: study compare Onset Duration Sensory Block; andDuration Motor Block other factors in two groups i.e.,...

background spinal anesthesia is a common procedure in the anesthesia. in some studies it has been shown that chronic use of opioids is associated with shorter duration of spinal anesthesia when local anesthetics are applied. objectives this trial was conducted in order to determine effect of fentanyl on the duration of spinal block by bupivacaine in chronic opium abusers who undergo spinal anes...

OBJECTIVE To determine the dose of hyperbaric bupivacaine 0.5% required for unilateral spinal anesthesia during diagnostic knee arthroscopy. PATIENTS AND METHODS This prospective, randomized, clinical study was performed in 80 patients who were assigned to four groups to receive different doses of intrathecal hyperbaric bupivacaine (5 mg, 7.5 mg, 10 mg and 12.5 mg in Groups 1, 2, 3, and 4 res...

Background and objectives: Subarachnoid block is most versatile regional block commonly employed for infraumbilical surgeries. The use of neuroaxial opioids has gained widespread popularity as they potentiate the analgesia produced by local anesthetics. Hence the present study was undertaken to evaluate the effects of intrathecally administered fentanyl (25mcg) on the characteristics of hyperba...

BACKGROUND AND OBJECTIVES The use of reduced intrathecal doses is advised for spinal anesthesia during cesarean delivery. However, there are inadequate data regarding the minimum effective dose of intrathecal bupivacaine for cesarean delivery. Preeclampsia is caused by an endothelial dysfunction leading to generalized vasoconstriction. Whether this can offset the pregnancy-induced decrease in i...

We used near-infrared spectroscopy (NIRS) to evaluate cerebral blood oxygenation changes in subjects undergoing cesarean section under spinal anesthesia (SP) with hyperbaric bupivacaine (group H, 27 subjects) or isobaric bupivacaine (group I, 15 subjects). In group H, total-Hb, oxy-Hb, and mean blood pressure (MBP) within 20 min after SP were significantly lower than the baseline values. In con...

OBJECTIVE To investigate the effects of selective spinal anaesthesia with low-dose bupivacaine alone and in combination with various doses of fentanyl, on blockage, haemodynamics, quality of anaesthesia, perioperative complications, and hospital release criteria. METHODS This prospective study included 45 ASA I-II patients (age range: 20-77 years). The cases were randomised into 3 groups: Gro...

background: after spinal anesthesia, patients undergoing cesarean section are more likely to develop hemodynamic changes. the baricity of local anesthetic has an important role on spinal blockade effects. the aim of this study was to compare the isobar and hyperbaric bupivacaine 0.5% plus fentanyl on maternal hemodynamics after spinal anesthesia for c/s. methods: in this double-blind study, 84 ...
