Several techniques have been proposed to prevent hypotension in obstetric patients. Ephedrine and phenylephrine are individually used to prevent maternal hypotension; however, each has its own drawbacks. Some researchers have reported that the infusion of combined ephedrine and phenylephrine immediately after spinal anesthesia for cesarean delivery reduces the incidence of maternal hypotension....

Spinal cord injury is a devastating chronic condition resulting in temporary or permanent motor,sensory or autonomic dysfunction of the cord. The manifestation of spinal cord injury based onthe severity and involved areas could be different. Numerous studies have demonstrated thatbradycardia, hypotension, and orthostatic hypotension are present insignificant number ofpat...

background despite controversies about the safest anesthetic technique for cesarean delivery in severely preeclamptic women, there is evidence that supports the use of spinal anesthesia in this group of patients. objectives this prospective randomized clinical trial was designed to determine the hemodynamic effects of low-dose spinal bupivacaine and the incidence of spinal anesthesia-associated...

abstract background: spinal anesthesia for cesarean section is associated with a high incidence of hypotension. the synergism between intrathecal opioids and local anesthetics may make it possible to achieve reliable spinal anesthesia with minimal hypotension using a minidose of local anesthetic. methods: forty-four preeclamptic parturients undergoing cesarean section were randomized in two gro...

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...
