Randomized Controlled TrialRandomized Double-Blind Study of the Effect of Injectate Temperature on Intrathecal Bupivacaine Dose Requirement in Spinal Anesthesia for Cesarean Delivery.
Increasing the temperature of intrathecal local anesthetics has been shown to increase the speed of onset and block height of spinal anesthesia. However, how this influences dose requirement has not been fully quantified. The aim of this study was to determine and compare the effective dose for anesthesia for cesarean delivery in 50% of patients (ED 50 ) of intrathecal bupivacaine given at temperatures of 37 °C (body temperature) or 24 °C (room temperature). ⋯ Warming hyperbaric bupivacaine to body temperature reduced the dose requirement for spinal anesthesia for cesarean delivery by approximately 16% (95% CI, 7%-23%).

Meta Analysis Comparative StudyComparison of Clinical Performance of I-gel and Fastrach Laryngeal Mask Airway as an Intubating Device in Adults: A Systematic Review and Meta-Analysis.
The supraglottic airway device (SGD) was introduced as a breakthrough in airway management. The Fastrach emerged as the first commercially available intubating SGD, drawing extensive investigation. I-gel is a more recent device that has gained popularity, can be used as an intubating SGD, and replaced Fastrach in many institutions. However, there is uncertainty regarding the comparison between these devices in terms of efficacy for intubation and ventilation, and safety in an airway rescue situation. ⋯ Based on our findings, a higher first-pass success rate was observed with the use of Fastrach when compared to I-gel. However, the use of I-gel might result in a better intubation success rate with the flexible scope-guided intubation. There are no significant differences in performance in terms of the success rate for intubation overall, time for device insertion, or time to intubation or complications regardless of the device used.

Multicenter Study Comparative StudyBronchial Blocker Versus Endobronchial Intubation in Young Children Undergoing One-Lung Ventilation: A Multicenter Retrospective Cohort Study.
Thoracic surgery and one-lung ventilation in young children carry significant risks. Approaches to one-lung ventilation in young children include endobronchial intubation (mainstem intubation) and use of a bronchial blocker. We hypothesized that endobronchial intubation is associated with a greater prevalence of airway complications compared to use of a bronchial blocker. ⋯ Endobronchial intubation might be associated with a slightly increased risk of critical airway complications compared to use of a bronchial blocker in young children undergoing thoracic surgery and one-lung ventilation. Further, prospective studies are needed before a definitive change in practice is recommended.

Multicenter Study Observational StudyChanges in Practices After Implementation of a Patient Blood Management Program in French Surgical Departments: The National Multicenter Observational PERIOPES Study.
Patient blood management (PBM) is an evidence-based approach recommended to improve patient outcomes. Change in practices is often challenging. We report here data from French surgical departments before and after a standardized implementation of a PBM program. ⋯ PBM practices in various surgical specialties improved significantly after the implementation of a PBM program. However, too many patients with preoperative anemia remained untreated.

Randomized Controlled Trial Multicenter Study Comparative StudyMcGrath MAC Versus Three-Dimensional Printed Video Laryngoscopes: A Randomized, Manikin-Simulated Noninferiority Controlled Study with Medical Students.
Proficiency in endotracheal intubation (ETI) is essential for medical professionals and its training should start at medical schools; however, large caseload may be required before achieving an acceptable success rate with direct laryngoscopy. Video laryngoscopy has proven to be an easier alternative for intubation with a faster learning curve, but its availability in medical training may be an issue due to its high market prices. We devised a low-cost 3-dimensionally printed video laryngoscope (3DVL) and performed a randomized trial to evaluate if the intubation success rate on the first attempt with this device is noninferior to a standard commercially available video laryngoscope (STVL). ⋯ The 3DVL was inferior in achieving first-attempt intubation when compared with the STVL with a difference in success rate >7.5% margin in simulated scenarios with medical students. Tracheal intubation might require a set of psychomotor skills for which the McGrath MAC device is superior to the low-cost alternative.
