ephedrine/nausea

Although reported in the aerospace literature and anecdotally by anesthesiologists, the putative antiemetic effect of ephedrine remains unquantitated. We therefore prospectively studied ephedrine as an antiemetic agent in the perioperative setting in 97 patients undergoing general anesthesia for

Postoperative nausea and vomiting (PONV) are relatively common troublesome distressing symptoms. The incidence is reported to be as high as 20-51%. Ninety adult ASA I and II patients scheduled for laparoscopic gynecological or surgical interventions, were randomly and equally assigned to one of the

Ephedrine, a well-known sympathomimetic agent, is used in the perioperative setting to treat acute hypotension, especially hypotension related to anesthetic events. Ephedrine's unlabeled use as an antiemetic agent is less well known despite its efficacy and safety profile for short-term and/or

OBJECTIVE To observe the effect of transcutaneous acupoint electric stimulation on the postoperative nausea and vomiting (PONV) and explore its mechanism. METHODS Ninety cases of elective cesarean section of I to II grade in American Society of Anesthesiologists (ASA) were collected and randomized

BACKGROUND Ingesting a combination of caffeine and ephedrine (C+E) has been shown to raise metabolic heat production and body temperature. This side effect of C+E ingestion may be positive during a cold stress scenario, however, during heat stress it could prove to be detrimental. Thus, the purpose

BACKGROUND Ingestion of a combination of 5 mg x kg(-1) caffeine (C), and 1 mg x kg(-1) ephedrine (E) was reported to have an ergogenic effect on high intensity aerobic exercise performance, but 25% of the subjects experienced vomiting and nausea while engaging in hard exercise after the treatment.

BACKGROUND Intrathecal morphine (ITM) is an excellent postoperative analgesic, but may often cause postoperative nausea and vomiting (PONV). We designed this prospective, randomized and controlled study to evaluate the antiemetic efficacy of low-dose droperidol for the treatment of PONV caused by

BACKGROUND Maternal hypotension is common after spinal anesthesia for cesarean delivery. We compared the effects of prophylactic ephedrine with ondansetron on post-spinal blood pressure. METHODS One hundred and sixty-eight term, singleton parturients were enrolled in this prospective, double-blind,

BACKGROUND Because ephedrine infusion (2 mg/min) does not adequately prevent spinal hypotension during cesarean delivery, the authors investigated whether adding phenylephrine would improve its efficacy. METHODS Thirty-nine parturients with American Society of Anesthesiologists physical status I-II

Ninety ASA I or II parturients were randomly allocated to three groups: group 10RL, 15RL and 20RL to receive 10, 15 and 20 mL/kg of Ringer's lactate (RL) respectively within 15 minutes (min) before the spinal block. Spinal anesthesia was performed with hyperbaric bupivacaine 12 mg, morphine 100

BACKGROUND Spinal anesthesia has been associated with intraoperative nausea and vomiting (IONV), especially during cesarean section, which is attributed to several mechanisms. OBJECTIVE In the present study, therapeutic and preventive properties of sub hypnotic dose midazolam and propofol and their

During December 1993-September 1995, the Bureau of Food and Drug Safety, Texas Department of Health (TDH), received approximately 500 reports of adverse events in persons who consumed dietary supplement products containing ephedrine and associated alkaloids (pseudoephedrine, norephedrine, and

BACKGROUND This randomized double blind study was started with an objective of management of spinal anaesthesia-induced hypotension in elective caesarean section by combining two commonly used vasopressors - ephedrine and phenylephrine in half of their usual doses with an expectation of reducing
