Association Between Two Muscle-Related Parameters and Postoperative Complications in Patients Undergoing Colorectal Tumor Resection Surgery.
This study aimed to investigate the associations of 2 preoperative muscle-related parameters, the third lumbar vertebra skeletal muscle index (L3 SMI) for muscle mass and the Hounsfield unit average calculation (HUAC) for muscle density, with the occurrence of postoperative complications among patients undergoing colorectal tumor resection surgery under general anesthesia. We hypothesized that muscle-related parameters are associated with the occurrence of postoperative complications. ⋯ A significant association was observed between myosteatosis and postoperative complications (corresponding to Clavien-Dindo classification before discharge), especially severe postoperative complications (Clavien-Dindo grade ≥3) in patients undergoing colorectal tumor resection. Screening for myosteatosis with HUAC using the CT before surgery may help clinicians identify high-risk perioperative patients early.

Earthquake Preparedness for Operating Room Staff: Lessons Learned From Experiences and the Literature.
Earthquakes pose hazards to health care workers and patients in operating rooms. Proactive planning based on insights gained from past experiences is crucial for enhancing safety. Through a comprehensive literature review, we summarize challenges and lessons learned from real earthquake events to inform the development of effective safety measures in operating rooms. Additionally, we discuss the anesthesiologist's role in crisis management.

Lassen's Cerebral Autoregulation Plot Revisited and Validated 65 Years Later: Impacts of Vasoactive Drug Treatment on Cerebral Blood Flow.
Niels Lassen's seminal 1959 cerebral autoregulation plot, a cornerstone in understanding the relationship between mean arterial pressure (MAP) and cerebral blood flow (CBF), was based on preexisting literature. However, this work has faced criticism for selective data presentation, leading to inaccurate interpretation. This review revisits and validates Lassen's original plot using contemporary data published since 2000. ⋯ Vasopressor treatment results in a greater increase in CBF during volatile than intravenous anesthesia. Modern antihypertensives do not significantly impact CBF based on contemporary data, exerting a smaller impact on CBF compared to historical data. These insights underscore the importance of individualized blood pressure management guided by modern data in the context of cerebral autoregulation across varied patient populations.
