background spinal anesthesia is an important and commonly used method for surgical anesthetic in operating rooms. however, even with identical drug dosage and administration mode, the extent of drug distribution in vivo is highly variable and difficult to control. preanesthetic administration of fluids immediately before spinal anesthesia (preload) is normal practice. the choice of fluid type m...

normal 0 false false false en-us x-none ar-sa background: regional anesthesia is widely used to perform different surgical procedures including those performed on the extremities . in this study, the anesthetic effects of adding intrathecal neostigmine or magnesium sulphate to bupivacaine in patients under lower extremities surgeries were assessed. materials and methods: in this double-blind ra...

the aim of this study was to assess the effect of spinal block with low dose of bupivacaine and sufentanil on patients with low cardiac output who underwent lower limb surgery. fifteen patients who had ejection fraction less than 40% (group 1) were compared with 65 cases with ejection fraction more than 40% (group 2) in our study. our subjects underwent spinal block with 7.5 mg hyperbaric bupiv...

background hip fracture–related pain both before and after surgery is generally reported as severe by most patients. various regional pain control modalities have been described in order to reduce pain in these patients. objectives because of the challenges of lumbar plexus block (lpb) and the fact that the effect of combined femoral nerve block/spinal anesthesia in controlling pain after ortho...

background: obtaining a good sensory and motor block is the goal of performing spinal anesthesia for surgeries. the aim of this study is to compare the effect of trendelenburg position on sensory block level after spinal anesthesia with intrathecal hyperbaric bupivacine. methods: we enrolled 80 men, classified as asa i, scheduled for elective hernia repair under spinal anesthesia. participants ...

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...

conclusions lidocaine does not have additive effects on duration and quality of spinal anesthesia with bupivacaine in those undergoing turp. results both study groups were comparable regarding the baseline characteristics. we did not find any difference between the two study groups regarding the duration of anesthetic block reaching the maximum level (p = 0.433) and duration of decreasing it to...
