The purpose of this study is to assess the effects of ephedrine on onset time of rocuronium, by comparing onset time when using rocuronium alone and with priming with rocuronium. In this randomized clinical trial, 120 patients with the American Anesthesiologists Society (ASA) class I/II who required laryngoscopy and tracheal intubation for elective surgery were assigned to 4 groups. Priming dos...

background: spinal anesthesia is an accepted technique in elective cesarean sections. however, hypotension, resulted from sympathectomy is a common problem, especially in pregnant women. prevention of this complication by sympathomimetic agents is of potential clinical significance. the aim of this study is to compare the effect of prophylactic infusion of phenylephrine versus ephedrine in the ...

the purpose of present study was to examine the effects of caffeine and ephedrine supplement and their combination on maximal strength and mucular endurance in male bodybuilders. 12 male bodybuilders (mean age: 24.41±4.42 years, height: 174.83±3.61 cm and weight: 75.67±8.05 kg) were selected voluntarily. the study design was crossover, in which the subjects were placed in 7 different conditions...

BACKGROUND Succinylcholine has been the neuromuscular blocking drug of choice for laryngoscopy and intubation, but it has several adverse effects. Nondepolarizing neuromuscular blocking drugs are good alternative provided their onset of action is hastened. Priming technique and use of ephedrine or MgSO4 pretreatment is good options. AIMS To compare the effects of priming and ephedrine pretrea...

Background: Spinal anesthesia is the recommended technique in elective cesarean sections. Usage of vasopressors more widely accepted as an effective method for decreasing postspinal hypotension than fluid loading. However, ideal vasopressor to prevent spinal during section has been a subject much debate. It should maintain maternal blood pressure and placental perfusion, with minimal adverse ef...

Background: Spinal anesthesia is often used for caesarean sections and there can be considerable hemodynamic changes following its use. Objective: To compare the commonly used vasopressors ephedrine and phenylephrine as well as the secondary effects of the co-administration of ephedrine and phenylephrine along with oxytocin on maternal hemodynamics. Design/Methods: This was a double-blind rando...
