Review Meta Analysis Comparative Study
Glidescope® video-laryngoscopy versus direct laryngoscopy for endotracheal intubation: a systematic review and meta-analysis.
The Glidescope(®) video-laryngoscopy appears to provide better glottic visualization than direct laryngoscopy. However, it remains unclear if it translates into increased success with intubation. ⋯ Compared to direct laryngoscopy, Glidescope(®) video-laryngoscopy is associated with improved glottic visualization, particularly in patients with potential or simulated difficult airways.

Randomized Controlled Trial Comparative Study
Use of a novel technique, solid phase microextraction, to measure tranexamic acid in patients undergoing cardiac surgery.
Solid phase microextraction (SPME) is a technique widely used and accepted in the field of food technology and in environmental and biological analyses. Despite its numerous advantages over older analytical methods, it has not been studied extensively in the medical sciences. Tranexamic acid (TXA) is currently the sole antifibrinolytic agent used during cardiac surgery involving the use of cardiopulmonary bypass (CPB). The current standard method of measuring TXA in plasma is based on plasma protein precipitation (PPP), but this analytical approach is time-consuming and not practical for routine use. The aim of the current study was to compare plasma TXA levels measured with the PPP method vs those acquired with the novel, highly efficient SPME technique. We also investigated the use of automated SPME with the aim of improving the technique so it could be used efficiently for measuring plasma TXA levels. ⋯ Solid phase microextraction is a relatively simple, rapid extraction technique that can facilitate future pharmacokinetic studies analyzing TXA drug concentrations and drug dosing in various clinical settings.

Randomized Controlled Trial
Effect of dexamethasone on postoperative morbidity after dental rehabilitation in children.
Dexamethasone reduces postoperative morbidity after adenotonsillectomy, strabismus surgery, and third molar extraction. Our hypothesis was that dexamethasone would reduce pain and other morbidity in children undergoing dental surgery for up to 24 hr postoperatively. ⋯ Dexamethasone, 0.3 mg·kg(-1), did not reduce pain over 24 hr in healthy children undergoing dental rehabilitation under general anesthesia. The quality of oral intake was also unaffected by dexamethasone at 24 hr. Dexamethasone did produce a significant reduction in postdischarge vomiting, beyond the incidence found with ondansetron alone.
