Randomized Controlled TrialIntravenous lidocaine has no impact on rocuronium-induced neuromuscular block. Randomised study.
Intravenous lidocaine is increasingly used in surgical patients. As it has neuromuscular blocking effects, we tested the impact of an intravenous lidocaine infusion on the time course of a rocuronium-induced neuromuscular block. ⋯ A continuous intravenous infusion of lidocaine has no impact on the time course of the neuromuscular blockade induced by a standard intubation dose of rocuronium.

Randomized Controlled Trial Comparative StudySevoflurane vs. propofol in patients with coronary disease undergoing mitral surgery: a randomised study.
Myocardial ischemic damage is reduced by volatile anaesthetics in patients undergoing low-risk coronary artery bypass graft surgery; few and discordant results exist in other settings. We therefore performed a randomised controlled trial (sevoflurane vs. propofol) to compare cardiac troponin release in patients with coronary disease undergoing mitral surgery. ⋯ In this study, patients with coronary artery disease undergoing mitral surgery did not benefit from the cardioprotective properties of halogenated anaesthetics. Sevoflurane anaesthesia was not associated to lower cardiac troponin release when compared with propofol anaesthesia.

Comparative StudyLack of agreement and trending ability of the endotracheal cardiac output monitor compared with thermodilution.
Minimally invasive monitoring systems of central haemodynamics are gaining increasing popularity. The present study investigated the precision of the endotracheal cardiac output monitor (ECOM) system and its agreement with pulmonary artery catheter thermodilution (PAC TD) for measuring cardiac output (CO) during steady state and with induced haemodynamic changes in patients scheduled for elective cardiac surgery. ⋯ In a direct comparison with PAC TD, the ECOM system did not show an acceptable agreement, with wide limits of agreement, a much larger percentage error than should be expected from the precision of the two methods and a very poor trending ability. Thus, the ECOM does not replace measurements done by thermodilution using a pulmonary artery catheter in cardiac surgery patients.

Increased risk for post-operative corneal injuries in patients who undergo laparoscopic gynecologic surgery.
The objective of this study was to verify whether or not the incidence of post-operative corneal injuries (PCIs) in patients who undergo laparoscopic gynecologic surgery is higher than patients who undergo non-laparoscopic gynecologic surgery. ⋯ Laparoscopic gynecologic surgery increases the incidence of PCI compared with non-laparoscopic gynecologic surgery.
