Acupuncture and related techniques are increasingly practiced in conventional medical settings, and the number of patients willing to use these techniques is increasing. Despite more than 30 yr of research, the exact mechanism of action and efficacy of acupuncture have not been established. Furthermore, most aspects of acupuncture have yet to be adequately tested. Therefore, considerable contro...

Forty-two patients, undergoing major gynaecological surgery, were randomly allocated to have a patch applied to the skin behind one ear, containing either hyoscine or placebo. They were followed up at 24-hour intervals for 3 days postoperatively and divided into matched pairs for statistical analysis. There was a significant (p less than 0.01) reduction in nausea and vomiting in the first 24 ho...

Structured abstract Question: In patients undergoing surgery, does prophylactic dimenhydrinate reduce the frequency of postoperative nausea and vomiting (PONV) compared to placebo? Data sources: Studies were identified by computerized searches (MEDLINE, EMBASE, Cochrane Library) up to June 2001, citation review, and hand searches of locally available anesthesia journals. No language restriction...

BACKGROUND Sex of female and laraproscopic surgery are both risk factors related to postoperative nausea and vomiting, and dexamethasone is used as anti-emetic in some operations. A meta-analysis of randomized trials was performed to determine the effect of prophylactic dexamethasone administration on postoperative nausea and vomiting, pain and complications in patients undergoing laparoscopic ...

BACKGROUND Postoperative vomiting is a common complication after strabismus surgery in children. The serotonin 5-HT(3) receptor antagonists have proven to be a particularly valuable addition to the armamentarium against postoperative nausea and vomiting (PONV). Palonosetron is a second-generation 5-HT(3) receptor antagonist that has recently been approved for prophylaxis against PONV. OBJECTI...

POSTOPERATIVE NAUSEA AND VOMiting (PONV) frequently complicates recovery from surgery. Before the 1960s, when older inhalational anesthetic agents such as ether and cyclopropane were widely used, the incidence of vomiting was as high as 60%. Better anesthetic techniques, along with a new generation of antiemetics and shorter-acting anesthetic drugs, have reduced the overall incidence of PONV to...

In a prospective, randomized, multicentre, double-blind, placebo-controlled study, we have compared the efficacy of a single i.v. dose of tropisetron 0.5 mg, 2 mg and 5 mg in the prevention of postoperative nausea and vomiting (PONV). We studied 385 ASA class I and II female patients undergoing abdominal or vaginal gynaecological surgery, including laparoscopy. Tropisetron or placebo were admin...

BACKGROUND AND OBJECTIVE Despite advantages of induction and maintenance of anaesthesia with sevoflurane, postoperative nausea and vomiting occurs frequently. Fentanyl is a commonly used supplement that may contribute to this, although it may also improve analgesia. METHODS This double-blind study examined the incidence and severity of postoperative nausea and vomiting and pain in the first 2...

Sir,—Koski and colleagues [1] found no difference in the incidence of nausea and vomiting in patients receiving transdennal hyoscine or placebo before operation. This is at variance with the findings of others [2]. A number of points warrant mention. In the study of Koski, different types of surgery were performed, whereas only patients having gynaecological surgery were studied by Uppington, D...
