Comparative Study
Algorithms for the prevention of postoperative nausea and vomiting: an efficacy and efficiency simulation.
A number of algorithms for the prevention of postoperative nausea and vomiting have been proposed. Their efficacy and efficiency remains unclear. ⋯ Despite improved knowledge on risk factors and antiemetic strategies, none of the tested algorithms completely prevents postoperative nausea and vomiting and none is universally applicable. Anesthesiologists should try to identify the most useful antiemetic strategy for a specific setting. That strategy may be prophylactic or therapeutic or a combination of both, and it should consider institutional policies and individual baseline risks.

Randomized Controlled Trial Comparative Study
A comparison of the laryngeal tube-S and Proseal laryngeal mask during outpatient surgical procedures.
The Laryngeal Tube Sonda (LTS) and the ProSeal Laryngeal Mask Airway (PLMA) are two new devices introduced for maintaining the airway during controlled ventilation under general anaesthesia. The present investigation compared their performance in a randomized controlled study. ⋯ Both devices provide a secure airway, are similar in clinical utility and are easy to insert. Better airway seal was detected in the PLMA group.

Randomized Controlled Trial Comparative Study
A comparison between bispectral index analysis and auditory-evoked potentials for monitoring the time to peak effect to calculate the plasma effect site equilibration rate constant of propofol.
To the best of our knowledge, the value of the plasma effect site equilibration rate constant (k(e0)) of propofol has not been reported in Chinese patients. The aim of this prospective, randomized study was to examine the characteristics of the time to peak effect (T(PEAK)) of propofol, a pharmacokinetic-independent descriptor of blood-brain equilibration, and k(e0) derived from T(PEAK) with A-line auditory-evoked potential monitor and Aspect A-2000 bispectral index monitor in Chinese patients. ⋯ The T(PEAK) of propofol measured by the A-line auditory-evoked potential monitor is different from that measured by the Aspect A-2000 bispectral index monitor. The T(PEAK)s of propofol from auditory-evoked potential index and bispectral index, and the values of k(e0) calculated based on T(PEAK)s are different from previous reports and appear to be not affected by age. Further studies need to be taken to validate clinically the k(e0) values of propofol.

Randomized Controlled Trial Comparative Study
The use of esmolol and magnesium to prevent haemodynamic responses to extubation after coronary artery grafting.
The haemodynamic responses during extubation can cause complications after open-heart surgery. In this study, we aimed to examine the effect of esmolol and magnesium before extubation on these haemodynamic responses. ⋯ We found that using esmolol before extubation following coronary artery bypass graft surgery prevents undesirable haemodynamic responses while magnesium reduces undesirable haemodynamic responses but does not prevent them.
