Randomized Controlled Trial Comparative Study Clinical TrialDesflurane versus propofol maintenance for outpatient laparoscopic cholecystectomy.
The aims of the study were to evaluate costs and clinical characteristics of desflurane-based anaesthetic maintenance versus propofol for outpatient cholecystectomy. ⋯ We conclude that desflurane is cheaper and has a more rapid emergence than propofol for outpatient cholecystectomy. However, propofol results in less pain and nausea in the recovery unit. Despite ondansetron and droperidol prophylaxis, there was still a substantial amount of nausea and vomiting after desflurane.

Randomized Controlled Trial Clinical TrialNausea and vomiting after major arthroplasty with spinal anaesthesia including morphine: a randomised trial of subhypnotic propofol infusion as prophylaxis.
Postoperative nausea and vomiting (PONV) following major arthroplasty with spinal anaesthesia and intrathecal morphine is reported in 45-74% of patients. This randomised, double-blind, placebo-controlled trial was undertaken to determine whether a subhypnotic infusion of propofol has a prophylactic antiemetic effect in this patient population. ⋯ These results suggest that routine use of postoperative, subhypnotic propofol infusion as PONV prophylaxis is not justified in this patient population.

Randomized Controlled Trial Comparative Study Clinical TrialHaemolysis following rapid experimental red blood cell transfusion--an evaluation of two infusion pumps.
The vast majority of infusion pumps used for rapid transfusion of large amounts of blood have never been properly examined regarding their influence on the quality of the red blood cells (RBCs) infused. In this study, we evaluated the effect of two different infusion pumps on the degree of RBC destruction following rapid experimental blood transfusion. ⋯ Both the pumps used in this study are safe alternatives for rapid transfusion of RBCs; however, with MRP this can be accomplished approximately twice as fast as with the PIP.

Comparative StudyAir contamination of a closed anesthesia circuit.
Closed-circuit anesthesia (CCA) has certain advantages such as decreased cost, decreased anesthetic gas pollution, improved inhalational gas humidity and temperature in comparison to conventional inhalational anesthesia using a high fresh gas flow, i.e. more than 2 L x min(-1), with a semi-closed breathing circuit. The main disadvantage of CCA is the possibility of hypoxic anesthetic gas delivery. ⋯ We herein present a case of air contamination of the breathing circuit through a sampling line of an anesthetic gas monitor. The air caused a decrease in the oxygen concentration during closed circuit anesthesia.

Effects of high thoracic epidural anaesthesia on the peripheral airway reactivity in dogs.
It has been speculated that epidural anaesthesia may induce bronchoconstriction via the mechanism of a sympathetic blockade. However, this hypothesis has not been confirmed by any experimental evidence. Therefore, we investigated the effects of high thoracic epidural anaesthesia with neural sympathetic blockade on basal airway resistance and airway reactivity in response to bronchoconstrictive stimuli in a canine periphery lung model. ⋯ Our results suggest that epidural anaesthesia with neural sympathetic blockade has no influence on the basal peripheral airway resistance; however, it prolongs the airway reactivity to Ach or His challenge, probably by the mechanism of reducing CO.
