Randomized Controlled Trial
The effects of lidocaine spray and intracuff alkalinized lidocaine on the occurrence of cough at extubation: a double-blind randomized controlled trial.
Our study aimed to evaluate the effects of lidocaine sprayed onto the larynx and/or injected into the tracheal tube cuff to decrease the incidence of cough at extubation and postoperative sore throat. ⋯ Sprayed lidocaine decreases the incidence of cough at tracheal extubation in surgeries of less than two hours. The use of alkalinized lidocaine into high-volume/low-pressure endotracheal cuffs had no impact on decreasing the incidence of cough or pain.

Randomized Controlled Trial
Preoperative pregabalin does not reduce propofol ED(50): a randomized controlled trial.
In many studies, gabapentinoids, such as pregabalin, have been shown to reduce preoperative anxiety. This anxiolysis is often accompanied by sedation, one of the most frequent side effects of pregabalin. We hypothesized that pregabalin taken preoperatively could reduce propofol requirements for induction of general anesthesia. ⋯ Preoperative pregabalin does not reduce propofol requirements in a population of healthy young women undergoing laparoscopic gynecologic procedures. This study failed to show a pre-induction anxiolytic effect of pregabalin in such a population. This trial was registered at www.clinicaltrials.gov (NCT01158859).

Platelet transfusion in cardiac surgery is often empiric as no established point-of-care tests are available for clear guidance of blood product administration, and there are many variables that can potentially increase the risk of bleeding during cardiopulmonary bypass. The objectives of this study were to determine the factors that influenced physicians' decisions to transfuse platelets perioperatively and to determine whether these factors coincide with characteristics using chart abstraction. ⋯ The use of focused physician questionnaires identified relevant aspects of patient care not apparent in the chart review that influenced the decision to transfuse platelets. The identification of bleeding, thrombocytopenia, more complex surgery, and the presence of liver disease highlights the requirement for standardized measures to assess the need for platelet transfusions in bleeding patients.
