Randomized Controlled TrialPrevention of Early Postoperative Decline: A Randomized, Controlled Feasibility Trial of Perioperative Cognitive Training.
Postoperative delirium and postoperative cognitive dysfunction (POCD) are common after cardiac surgery and contribute to an increased risk of postoperative complications, longer length of stay, and increased hospital mortality. Cognitive training (CT) may be able to durably improve cognitive reserve in areas deficient in delirium and POCD and, therefore, may potentially reduce the risk of these conditions. We sought to determine the feasibility and potential efficacy of a perioperative CT program to reduce the incidence of postoperative delirium and POCD in older cardiac surgery patients. ⋯ A CT program designed for use in the preoperative period is an attractive target for future investigations of cognitive prehabilitation in older cardiac surgery patients. Changes in the functionality of the program and enrichment techniques may improve adherence in future trials. Further investigation is necessary to determine the potential efficacy of cognitive prehabilitation to reduce the risk of postoperative delirium and POCD.

ReviewPathophysiological Response to Trauma-Induced Coagulopathy: A Comprehensive Review.
Hypercoagulability can occur after severe tissue injury, that is likely related to tissue factor exposure and impaired endothelial release of tissue plasminogen activator (tPA). In contrast, when shock and hypoperfusion occur, activation of the protein C pathway and endothelial tPA release induce a shift from a procoagulant to a hypocoagulable and hyperfibrinolytic state with a high risk of bleeding. ⋯ Response to trauma is a complex, dynamic process in which risk can shift from bleeding to thrombosis depending on the injury pattern, hemostatic treatment, individual responses, genetic predisposition, and comorbidities. Based on this body of knowledge, we will review and consider future directions for the management of severely injured trauma patients.

Observational StudyEpidural Analgesia During Childbirth and Postpartum Depressive Symptoms: A Population-Based Longitudinal Cohort Study.
Severe pain has been linked to depression, which raises the question of whether epidural analgesia (EDA) during childbirth is associated with a reduced risk of postpartum depression (PPD). This association has been explored previously, but the studies were restricted by small sample sizes and the inability to control for relevant confounders. This study aimed to investigate the association between the administration of EDA and the development of PPD after adjusting for sociodemographic, psychosocial, and obstetric variables. ⋯ EDA was not associated with the risk of PPD at 6 weeks postpartum after adjusting for sociodemographic, psychosocial, and obstetric variables. However, these findings do not preclude a potential association between PPD and childbirth pain or other aspects of EDA that were not assessed in this study.

Prospective Investigation of the Operating Room Time-Out Process.
Although the surgical pause or time-out is a required part of most hospitals' standard operating procedures, little is known about the quality of execution of the time-out in routine clinical practice. An interactive electronic time-out was implemented to increase surgical team compliance with the time-out procedure and to improve communication among team members in the operating room. We sought to identify nonroutine events that occur during the time-out procedure in the operating room, including distractions and interruptions, deviations from protocol, and the problem-solving strategies used by operating room team members to mitigate them. ⋯ Compliance with preincision time-outs is high at our institution, and nonroutine events are a rare occurrence. It is common for ≥1 member of the operating room team to be actively distracted during time-out procedures, even though most time-outs are completed in under 1 minute. Despite distractions, there were no wrong-site or wrong-person surgeries reported at our hospital during the study period. We conclude that the simple act of performing a preprocedure checklist may be completed quickly, but that distractions are common.

Observational StudyPrincipal Factors Associated With Ketorolac-Refractory Pain Behavior After Pediatric Myringotomy and Pressure Equalization Tube Placement: A Retrospective Cohort Study.
Prophylactic analgesic administration reduces pain behavior after pediatric bilateral myringotomy and pressure equalization tube placement (BMT). We hypothesized that postoperative pain in children treated with intraoperative ketorolac would, among several exposures of interest, be strongly associated with ear condition. ⋯ Pain behavior after BMT varies by surgeon and is strongly associated with ear condition. Ketorolac as a single prophylactic analgesic appears less effective in younger children with normal middle ear findings.
