BACKGROUND I.V. fluid administration has been shown to reduce postoperative nausea and vomiting (PONV). The optimum dose is unknown. We tested the hypothesis that administration of i.v. crystalloid of 30 ml kg(-1) would reduce the incidence of PONV compared with 10 ml kg(-1) of the same fluid. METHODS A total of 141 ASA I female patients undergoing(More)
We have compared the analgesic effects of diclofenac given before operation or immediately after operation in a randomized, double-blind, double-dummy study of 40 healthy female patients undergoing laparoscopic tubal ligation. Group 1 patients received diclofenac 75 mg as a 3-ml i.m. injection 1-2 h before operation and normal saline 3 ml i.m. immediately(More)
Severe sepsis, a syndrome characterized by systemic inflammation and acute organ dysfunction in response to infection, is a major healthcare problem affecting all age groups throughout the world. Anaesthetists play a central role in the multidisciplinary management of patients with severe sepsis from their initial deterioration at ward level, transfer to(More)
The ratio of hepatic arterial-to-portal venous blood flow can be determined from the analysis of a first-pass bolus through the liver by a number of techniques. This study examines the validity of four radiotracer techniques in an animal model. Thirty-four flow studies (3 mCi 99mTc-DTPA/study) were performed in seven anesthetized pigs. Images were acquired(More)
BACKGROUND Halothane and isoflurane depress myocardial contractility by decreasing transsarcolemmal Ca2+ influx and Ca2+ release from the sarcoplasmic reticulum. Decreases in Ca2+ sensitivity of the contractile proteins have been shown in skinned cardiac fibers, but the relative importance of this effect in intact living myocardium is unknown. The aims of(More)
Ketamine is a cardiovascular stimulant through its sympathomimetic effects; however, its direct inotropic effect has been reported as positive in rat and negative in rabbit ventricular myocardium. This study reexamines the effect of ketamine on the contractile properties of mammalian ventricular myocardium. In isolated, electrically stimulated ferret right(More)
BACKGROUND Abiraterone (ABI) is a major oral agent for the treatment of metastatic castration-resistant prostate cancer (mCRPC) patients but its systemic exposure is subject to a large inter-individual variability. We aimed to explore the relationship between ABI trough plasma concentration and prostate-specific antigen (PSA) response in mCRPC patients and(More)
The effects of nitrous oxide on variables of contractility and relaxation were analyzed in isolated ferret right ventricular papillary muscles. Each mechanical variable, in isometric, isotonic, and zero-load-clamped twitches, was compared to the average value of that variable in control conditions (50% nitrogen in oxygen), before and after equilibration(More)
