Complications and Technical Consideration of Ultrasound-Guided Rectus Sheath Blocks: A Retrospective Analysis of 4033 Patients.
Although the ultrasound-guided rectus sheath block (RSB) is usually regarded as an easy and safe procedure in clinical settings, there is currently no report on complications incidence. Therefore, the present study investigated complications in a large cohort and described the technical considerations to minimize complications of real-time ultrasound-guided RSBs. ⋯ In this study of RSBs performed on 4033 patients using a 23-gauge Quincke needle in patients with low body mass index, there were 8 cases (0.2%) of vascular injury, all of which accompanied hematoma.

The aim of this study was to explore the incidence of early bifurcation of the right hepatic artery (RHA) and the right posterior hepatic artery (RPHA), which is crucial in right lobe graft (RLG) and right posterior sector graft (RPSG) procurement for living-donor liver transplantation. ⋯ Early bifurcation of the RHA and the RPHA is frequently encountered and requires caution for RLG/RPSG procurement. Special attention should be paid to supraportal RPHA for RLG procurement.

To identify risk factors for tumor positive resection margins after neoadjuvant chemoradiotherapy (nCRT) followed by esophagectomy for esophageal cancer. ⋯ In this nationwide cohort study, tumor and surgical related factors (tumor length, histology, cT-stage, tumor location, surgical procedure, surgical approach, hospital volume) were identified as risk factors for tumor positive resection margins after nCRT for esophageal cancer. These results can be used to improve the radical resection rate by careful selection of patients and surgical approach and are a plea for centralization of esophageal cancer care.

Pro-Con Debate: Are Patients With Coronary Stents Suitable for Free-Standing Ambulatory Surgery Centers?
With increasing implantation of coronary artery stents over the past 2 decades, it is inevitable that anesthesiologists practicing in the outpatient setting will need to determine whether these patients are suitable for procedures at a free-standing ambulatory surgery center (ASC). Appropriate selection of patients with coronary artery stents for a procedure in an ASC requires consideration of factors that affect the balance between the risk of stent thrombosis due to interruption of antiplatelet therapy and the thrombogenic effects of surgery, and the risk of perioperative bleeding complications that may occur if antiplatelet therapy is continued. ⋯ Therefore, the suitability of the ambulatory setting for this patient population remains highly controversial. In this Pro-Con commentary, we discuss the arguments for and against scheduling patients with coronary artery stents in free-standing ASCs.

Although the analgesic effects of ether were conclusively established during a series of public demonstrations of anesthesia at Massachusetts General Hospital in 1846, ether anesthesia was neither immediately nor universally introduced into practice. Betsey Magoun, the fourth patient undergoing surgery under anesthesia at the hospital, suffered life-threatening hypoxia and respiratory complications. Severe intraoperative problems witnessed by large audience may have contributed to the cautious introduction of anesthesia into routine practice. Ether inhalation was not commonly used until more effective methods of induction and maintenance of anesthesia were discovered.
