The influence of body-mass index (BMI) on spinal anesthesia is still controversial, with discrepant results reported in previous studies. To compare spinal anesthesia in obese and non-obese subjects, the anesthesia profiles in patients who underwent spinal anesthesia using intrathecal hyperbaric bupivacaine were compared. A total of 209 patients undergoing elective total knee replacement arthro...

conclusions this study showed that the addition of intrathecal magnesium sulfate to bupivacaine is not desirable in patients undergoing cesarean section due to the delay in the onset of sensory blockade and the lack of significant effects of magnesium on post-operative pain. results the onset of sensory blockade was delayed in case group compared with control group, and this was statistically s...

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...

BACKGROUND There are limited data to determine the impact of subarachnoid blockade with local anesthetics on perioperative pulmonary function. The effects of local anesthetics used in spinal anesthesia are very important in terms of respiratory function in patients with chronic obstructive pulmonary disease (COPD). OBJECTIVE The aim of this study was to evaluate the effects of bupivacaine ver...

background: shivering is one of the common problems in spinal anesthesia. the objective of the present study was to evaluate the effect of intrathecal fentanyl (25 μg) on incidence and severity of intraoperative and postoperative shivering. methods: a double-blind randomized controlled study was conducted in eighty healthy women (asa physical status i) scheduled for elective cesarean section un...

We have studied 20 primiparous women requesting pain relief for labour, to determine the feasibility of subarachnoid infusions of bupivacaine for analgesia. A 28-gauge catheter was inserted into the subarachnoid space through a modified 22-gauge Sprotte needle. After a bolus dose of up to 1.5 ml of 0.25% bupivacaine, a continuous infusion of 0.125% bupivacaine was commenced. If analgesia became...

BACKGROUND Some investigators found a greater incidence of hypotension in patients receiving intrathecal hyperbaric solution than in patients receiving plain solution for cesarean section. OBJECTIVE Compare the effects of intrathecal hyperbaric bupivacaine 10 mg with intrathecal bupivacaine 11 mg and intrathecal levobupivacaine 11 mg, all with 10 microg of fentanyl, for cesarean section. MA...
