Arterial blood pressure (BP) measurement at least every 5 minutes is part of the American Society Anesthesiologists' monitoring standard, but prolonged BP gaps in electronic anesthesia records have been noted. We undertook multicenter studies to determine frequency cases with 1 interval ≥10 between successive measurements and then ascertain whether educational feedback via an electronic, near real-time notification system alerting providers presence such would reduce their incidence.We...

Abstract Purpose The objective examination of the Post-COVID syndrome (PCS) remains difficult due to heterogeneous definitions and clinical phenotypes. aim study was verify functionality correlates a recently developed PCS score. Methods score applied prospective, multi-center cross-sectoral cohort (in- outpatients with SARS-CoV-2 infection) "National Pandemic Cohort Network (NAPKON, Germany)". Symptom assessment patient-reported outcome measure questionnaires were analyzed at 3 12 months...

In Brief BACKGROUND: Antithrombin (AT) levels decrease during cardiopulmonary bypass (CPB), particularly when combined with deep hypothermic circulatory arrest (DHCA). Low AT might lead to imbalance of pro- and anticoagulant factors promoting systemic thrombotic events. We hypothesized that low increased in vitro thrombin generation procoagulant are added the patient's plasma after CPB. METHODS: Blood samples were obtained before heparinization separation from CPB five patients undergoing...

Thrombin is a key hemostatic enzyme, which propagates its own generation by activating factors V, VIII, and XI. Sustained thrombin also activates thrombin-activatable fibrinolysis inhibitor (TAFI), stabilizes fibrin clot against fibrinolysis. Recombinant activated factor VII (rFVIIa) considered novel intervention for refractory bleeding, but rebleeding episodes related to still occur. The present study aimed investigate the antifibrinolytic effects of rFVIIa in relation generation. Using...

The patient developed after closure tracheostomy, which occurred during from trauma involving vertebral, rib, pelvic fractures as well bilateral pneumothoraces. was initially jet-ventilated 14 French After sufficient dilation, this replaced 5.0-mm laser-shielded endotracheal tube, the ventilated uneventfully for...

A 66-year-old man with a history of large anteroapical myocardial infarction presented to the operating room for three-vessel coronary artery bypass grafting and left ventricular (LV) reconstructive surgery (Dor procedure). His baseline intraoperative transesophageal echocardiography demonstrated dilated LV an end diastolic diameter >7 cm ejection fraction <20%. central jet severe mitral regurgitation (MR) was present, causing systolic flow reversal in pulmonary veins. The mechanism appeared...

Failure of a double-lumen endotracheal tube (DLT) to isolate the lung during thoracic surgery can have significant consequences. In this report, we examine an approach for rescuing malpositioned DLT. A 37F left-sided DLT was inserted and its proper position confirmed. After positioning, repeat confirmation ability achieve 1-lung ventilation were performed, but inadequate isolation being operated on noted after incision. 7-Fr Arndt bronchial blocker positioned through tracheal lumen obtain...

Heparin resistance is a common complication of surgical patients requiring anticoagulation, such as those undergoing cardiopulmonary bypass (CPB). Treatments to address heparin include supplementation antithrombin (AT) or fresh frozen plasma (FFP). This retrospective database analysis compared key outcomes in suspected heparin-resistant CPB treated with AT FFP.De-identified United States electronic health records (Cerner Health Facts®) were queried.

Objectives: The saphenous vein is still one of the most commonly used grafts for coronary artery bypass grafting. Nevertheless, several studies show an inferior long-term patency compared to arterial grafts. This could be due histologic structure which may altered under higher pressure and intraoperative handling graft, especially accidental peak pressures over 600 mmHg leading endothelial damage graft. Endothelial prevented by controlled flushing Therefore, we investigated whether usage a...

Nevertheless several studies show an inferior long term patency compared to arterial grafts. This could be due histologic structure as it not intended a high pressure system. Another issue might intraoperative handling graft.

ABSTRACT The use of transesophageal echocardiography (TEE) has improved the detection venous air embolism (VAE), especially in case small VAE where clinical changes can be subtle and erroneously attributed to volume status or cardiac function. We present a 62 years old female that occurred during anterior lumbar spine surgery was diagnosed with aid TEE. As spines is traditionally not associated VAE, we believe this first reported type procedure. How cite article Cho SJ, Bader SO, Heitz JW....
