conclusions administration of two different doses of intravenous ondansetron, 6 mg and 12 mg, significantly attenuates spinal induced hypotension, bradycardia and shivering compared to the control saline group. however, the hemodynamic profiles and shivering in experimental groups were not statistically different. results demographic data were not statistically different among groups. hr was st...

background hypotension during spinal anesthesia is common and can lead to severe injuries and even death. administration of crystalloid fluids is advised to prevent occurrence of hypotension; however its effectiveness is still the matter of arguments. objectives this study was designed to compare the effects of ringer`s lactate and hydroxyethyl starch 6% on hemodynamic parameters after spinal a...

BACKGROUND Hypotension is a common phenomenon after spinal anesthesia in hypertensive patients. We investigated whether heart rate variability could predict the occurrence of hypotension after spinal anesthesia in hypertensive patients. METHODS Forty-one patients undergoing spinal anesthesia were included. Heart rate variability was measured at five different time points such as before fluid ...

Background and Aims: During Cesarean section, hypotension occurs in the most of parturients, following spinal anesthesia. This prospective observational study was undertaken to determine efficacy two different Bolus Doses Phenylephrine for Prevention Spinal-Induced Hypotension during Section.
 Materials Methods: A total 120 parturients undergoing cesarean section were divided into groups g...

acute paraplegia is a rare but catastrophic complication of surgeries performed on aorta and corrective operations of vertebral column. trauma to spinal cord after spinal anesthesia and ischemia of spinal cord also may lead to acute paraplegia. acute paraplegia as a complication of general anesthesia in surgeries performed on sites other than aorta and vertebral column is very rare. here we pre...

BACKGROUND AND OBJECTIVE Spinal anaesthesia for caesarean section is commonly associated with hypotension and crystalloid preload is widely recommended. Low-dose spinal appears to cause less hypotension. The aim of this study was to investigate whether the combined use of crystalloid preload and low dose spinal anaesthesia might further reduce the rates of hypotension. METHODS Sixty-two patie...

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 ...
