Observational StudyA Prospective Observational Study of Technical Difficulty With GlideScope-Guided Tracheal Intubation in Children.
The GlideScope Cobalt is one of the most commonly used videolaryngoscopes in pediatric anesthesia. Although visualization of the airway may be superior to direct laryngoscopy, users need to learn a new indirect way to insert the tracheal tube. Learning this indirect approach requires focused practice and instruction. Identifying the specific points during tube placement, during which clinicians struggle, would help with targeted education. We conducted this prospective observational study to determine the incidence and location of technical difficulties using the GlideScope, the success rates of various corrective maneuvers used, and the impact of technical difficulty on success rate. ⋯ A variety of clinicians experience technical difficulties with the GlideScope Cobalt videolaryngoscope in children. These difficulties result in more tracheal intubation attempts, an important risk factor for intubation-associated complications. Targeted education of clinicians may reduce the incidence of technical difficulties.

An estimated 25 million people identify as transgender worldwide, approximately 1 million of whom reside in the United States. The increasing visibility and acceptance of transgender people makes it likely that they will present in general surgical settings; therefore, perioperative health care providers must develop the knowledge and skills requisite for the safe management of transgender patients in the perioperative setting. ⋯ It is essential that anesthesia providers develop the knowledge and skills necessary for safely managing transgender patients in the perioperative setting. This review provides an overview of relevant terminology, the imperative for the provision of culturally sensitive care, and guidelines for preoperative, intraoperative, and postoperative management of the transgender patient.

Repeated Measures Designs and Analysis of Longitudinal Data: If at First You Do Not Succeed-Try, Try Again.
Anesthesia, critical care, perioperative, and pain research often involves study designs in which the same outcome variable is repeatedly measured or observed over time on the same patients. Such repeatedly measured data are referred to as longitudinal data, and longitudinal study designs are commonly used to investigate changes in an outcome over time and to compare these changes among treatment groups. From a statistical perspective, longitudinal studies usually increase the precision of estimated treatment effects, thus increasing the power to detect such effects. ⋯ Such methods can be further divided into so-called "population-average statistical models" that focus on the specification of the mean response of the outcome estimated by generalized estimating equations, and "subject-specific models" that allow a full specification of the distribution of the outcome by using random effects to capture within-subject correlations. The choice as to which approach to choose partly depends on the aim of the research and the desired interpretation of the estimated effects (population-average versus subject-specific interpretation). This tutorial discusses aspects of the theoretical background for each technique, and with specific examples of studies published in Anesthesia & Analgesia, demonstrates how these techniques are used in practice.

Comparative StudyOutcomes in Patients Undergoing Cardiac Surgery Who Decline Transfusion and Received Erythropoietin Compared to Patients Who Did Not: A Matched Cohort Study.
Erythropoiesis-stimulating agents, such as erythropoietin (EPO), can be used to treat preoperative anemia. Some studies suggest an increased risk of mortality and thrombotic events, and use in cardiovascular surgery remains off-label. This study compares outcomes in cardiac surgery patients declining blood transfusion who received EPO with a matched cohort who did not. ⋯ In this retrospective matched cohort study of patients declining transfusion and receiving EPO matched to control patients, there were no clinically meaningful differences in the outcomes.
