Tranexamic acid (TXA) reduces perioperative blood loss and transfusion requirement following cardiac surgery. Nevertheless, TXA remains underutilized because of concerns regarding development of adverse events. We conducted a systematic review to determine which patients are commonly excluded from TXA cardiac surgery clinical trials to determine if there are patient groups lacking safety data on TXA. ⋯ We found that systemic TXA is safe to use in cardiac surgery. Certain patient groups are frequently excluded from TXA cardiac surgery trials, and may consequently have limited efficacy and safety data on TXA. Further research in these patient groups may be needed; nevertheless, for many patient populations there are sufficient data to inform evidence-based guidelines for TXA use in cardiac surgery.

Meta Analysis
Lidocaine lubricants for intubation-related complications: a systematic review and meta-analysis.
Postoperative sore throat (POST) is a relatively common morbidity. Topical lidocaine lubricants have been proposed to prevent POST; however, their effectiveness remains uncertain. This meta-analysis aimed to evaluate the prophylactic effect of lidocaine lubrications against POST, cough, and hoarseness in adult patients after surgery. ⋯ Lidocaine lubricants applied on the tips of endotracheal tube are not effective against the morbidities of POST, PC, and PH.

Randomized Controlled Trial Comparative Study
Randomized comparison of McGrath MAC videolaryngoscope, Pentax Airway Scope, and Macintosh direct laryngoscope for nasotracheal intubation in patients with manual in-line stabilization.
The objective of this study was to determine the clinical usefulness of videolaryngoscopes (VLs) by comparing the time to intubation (TTI) and the ease of intubation of McGrath MAC VL (MVL), Pentax Airway Scope VL (PVL), and Macintosh direct laryngoscope (DL) during nasotracheal intubation using manual in-line stabilization to simulate difficult airways. ⋯ This study showed that both MVL and PVL provided better visualization of the glottis and easier intubation, with less additional manipulation than DL during nasotracheal intubation in simulated difficult airways. Additionally, use of the MVL significantly shortened the TTI compared with the DL.
