Randomized Controlled Trial Comparative Study Clinical Trial
Haemodynamic and electroencephalograph responses to intubation during induction with propofol or propofol/fentanyl.
To observe the changes in EEG bispectral index (BIS), 95% spectral edge frequency (95% SEF) and median frequency (MF) with haemodynamic changes to intubation during induction with propofol or propofol and 2 micrograms.kg-1 fentanyl i.v. ⋯ Fentanyl, 2 micrograms.kg-1 i.v., blunted the haemodynamic responses to intubation, but failed to attenuate the arousal of cerebral cortical activity. The different haemodynamic responses postintubation but similar BIS and 95% SEF changes in the two groups suggest that BIS or 95% SEF cannot predict the haemodynamic responses to intubation during anaesthesia induction with propofol and fentanyl.

Randomized Controlled Trial Comparative Study Clinical Trial
Heparin and protamine titration do not improve haemostasis in cardiac surgical patients.
Weight-based heparin and protamine dosing strategies for cardiopulmonary bypass (CPB) do not take into account interpatient variability in drug sensitivity and may result in bleeding complications. We compared the Hemochron RxDx heparin and protamine titration system with standard weight based management with regard to heparin dose, protamine dose, and perioperative bleeding. ⋯ In cardiac surgical patients, heparin and protamine titration did predict a lower protamine dose but did not result in a measurable improvement in haemostasis during the perioperative period.

Randomized Controlled Trial Clinical Trial
Postoperative analgesia with "3-in-1" femoral nerve block after prosthetic hip surgery.
To evaluate the efficacy of a single shot "3-in-1" femoral nerve block for prosthetic hip surgery in association with general anaesthesia on post-operative analgesia. ⋯ There is a short-term benefit during the first few postoperative hours in using a single shot "3-in-1" femoral nerve block to complement general anaesthesia for elective hip surgery.
