Ventilation of the lungs with positive end-expiratory pressure during pneumoperitoneum has been shown to improve the arterial partial pressure of oxygen. The implications of spontaneous breathing on pulmonary gas exchange remain unknown in this setting. We therefore sought to examine the influence of pressure-support ventilation with spontaneous breathing on gas exchange during simulated laparoscopy. ⋯ Pressure-support ventilation resulted in significantly better gas exchange than pressure-controlled ventilation in this model of simulated laparoscopy.

We measured the physical performance error of commercial syringe pumps incorporating the Diprifusor module to deliver propofol by target-controlled infusion in a laboratory experiment. ⋯ Despite the differences between the pumps, which may be related to the synchronization of the hardware components, the absolute inaccuracies in the physical performance were low and presumably negligible from a clinical point of view.

The study aimed to evaluate and improve airway management in the prehospital setting, i.e. physicians working on board ambulances. A quality control programme focusing on anaesthesia was instituted to improve the time taken to perform endotracheal intubation. ⋯ The time to perform tracheal intubation can be improved by the introduction of succinylcholine into the prehospital anaesthetic protocol. Rapid sequence induction should be taught as a way of improving tracheal intubation in the prehospital setting.

Randomized Controlled Trial Comparative Study Clinical Trial
Comparison of the effects of remifentanil or fentanyl on anaesthetic induction characteristics of propofol, thiopental or etomidate.
This prospective, randomized, double-blinded study was designed to compare the effects of remifentanil or fentanyl on anaesthetic induction characteristics of propofol, thiopental or etomidate. ⋯ During anaesthetic induction, a remifentanil infusion of 0.5 microg kg(-1) min(-1) over 5 min is a suitable alternative to a 1.5 microg kg(-1) bolus dose of fentanyl: induction times are shorter with reduced amounts of propofol, thiopental or etomidate.

Randomized Controlled Trial Comparative Study Clinical Trial
Intravenous single-dose tramadol versus meperidine for pain relief in renal colic.
Comparison of the effectiveness of tramadol with meperidine given intravenously to emergency patients with suspected renal colic. ⋯ Meperidine 50 mg was superior to tramadol 50 mg for acute pain relief in patients with suspected renal colic when given intravenously. Because many patients in both groups received supplemental meperidine and the response to tramadol alone cannot be predicted, clinicians may want to choose higher doses of meperidine alone or other alternative combinations.
