transfusion in surgical patients

BACKGROUND: During the coronavirus disease (COVID-19) pandemic, medical resources have often been limited to emergency surgeries. This study aimed to evaluate our experience with delayed surgery for acute type A aortic dissections (ATAADs). METHODS: A retrospective study was conducted on 33 patients who underwent surgery for ATAADs between January 2020 and December 2021. The patients were divided into two groups: patients treated within 12 h of arrival (E group; N = 21) and those treated > 12 h after arrival (D group; N = 12) with strict antihypertensive therapy until surgery...

INTRODUCTION: Studies have reached mixed conclusions on the role of antiplatelet and anticoagulant agents on postoperative complications of partial nephrectomies. This study examines whether preoperative anticoagulation use affected the risk of hemorrhagic complications after partial nephrectomy. MATERIALS AND METHODS: This is a retrospective chart review of all partial nephrectomies performed between 2017 and 2022 at a single institution. For each operation, preoperative data was gathered on whether the patient was on anticoagulation, the type and dose of anticoagulation, and how many days the anticoagulation was held preoperatively...

BACKGROUND: Abdominal wall reconstruction requires extensive dissection of the abdominal wall, exposure of the retroperitoneum, and aggressive chemoprophylaxis to reduce the risk of thromboembolic complications. The need for early anticoagulation puts patients at risk for bleeding. We aimed to quantify postoperative blood loss, incidence of transfusion and reoperation, and associated risk factors in patients undergoing complex abdominal wall reconstruction. METHODS: All patients underwent a posterior component separation with transversus abdominis release and placement of retromuscular mesh for ventral hernias <20 cm wide and were enrolled in a clinical trial assessing the utility of trans-fascial mesh fixation...

BACKGROUND: The optimal surgical approach for Bismuth II hilar cholangiocarcinoma (HCCA) remains controversial. This study compared perioperative and oncological outcomes between minor and major hepatectomy. MATERIALS AND METHODS: One hundred and seventeen patients with Bismuth II HCCA who underwent hepatectomy and cholangiojejunostomy between January 2018 and December 2022 were retrospectively investigated. Propensity score matching created a cohort of 62 patients who underwent minor (n = 31) or major (n = 31) hepatectomy...

BACKGROUND: Our goal was to create a simple risk-prediction model for renal function decline after cardiac surgery to help focus renal follow-up efforts on patients most likely to benefit. METHODS AND RESULTS: This single-center retrospective cohort study enrolled 24 904 patients who underwent cardiac surgery from 2012 to 2019 at Fuwai Hospital, Beijing, China. An estimated glomerular filtration rate (eGFR) reduction of ≥30% 3 months after surgery was considered evidence of renal function decline...

BACKGROUND: Aneurysmal subarachnoid hemorrhage (SAH) is catastrophic, and microsurgery for ruptured intracranial aneurysms is one of the preventive modalities for rebleeding. However, patients remain at high risk of medical morbidities after surgery, one of the most important of which is health care-associated infections (HAIs). We analyzed the incidence and risk factors of HAIs, as well as their association with the outcomes after surgical treatment of ruptured aneurysms. METHODS: We retrospectively enrolled 607 patients with SAH who had undergone surgery for intracranial aneurysms...

OBJECTIVES: To present a new method for displaying blood utilization data based on analysis of decision time intervals (DTIs). METHODS: Retrospective study of patients treated in a medical intensive care unit (ICU), surgical ICU, or postcardiac surgery ICU at an academic hospital between January 2018 and June 2023. Each patient's episode of care was divided into a series of DTIs. Transfusions during each time interval were recorded. RESULTS: In total, 16,562 patients received 6980 units of plasma and 21,034 units of red blood cells during 111,557 time intervals of care...

OBJECTIVE: The association between fluid balance and outcomes in patients who underwent out-of-hospital cardiac arrest (OHCA) and received extracorporeal cardiopulmonary resuscitation (ECPR) remains unknown. We aimed to examine the above relationship during the first 24 h following intensive care unit (ICU) admission. METHODS: We performed a secondary analysis of the SAVE-J II study, a retrospective multicenter study involving OHCA patients aged ≥ 18 years treated with ECPR between 2013 and 2018 and who received fluid therapy following ICU admission...

BACKGROUND: The indication of laparoscopic liver resection (LLR) for treating large hepatocellular carcinoma (HCC) is controversial. In this study, we compared the short-term and long-term outcomes of LLR and open liver resection (OLR) for large HCC. MATERIAL AND METHODS: We searched eligible articles about LLR versus OLR for large HCC in PubMed, Cochrane Library, and EMBASE and performed a meta-analysis. RESULTS: Eight publications involving 1,338 patients were included...

OBJECTIVES: To compare surgical and functional outcomes between off-clamp robot-assisted partial nephrectomy with indocyanine-green tumour marking through preliminary superselective embolization and on-clamp robot-assisted partial nephrectomy with intraoperative ultrasound identification of the renal mass. MATERIAL AND METHODS: One hundred and forty patients with a single renal mass underwent indocyanine-green fluorescence-guided off-clamp robot-assisted partial nephrectomy with preoperative superselective embolization (Group A, 70 patients) versus intraoperative ultrasound-guided on-clamp robot-assisted partial nephrectomy without embolization (Group B, 70 patients)...

INTRODUCTION: Upper tract urothelial carcinoma (UTUC) is a rare disease accounting only for 5%-10% of urothelial carcinoma (UC). For localized high-risk disease, radical nephroureterectomy (RNU) is the standard of care. While minimally invasive (MIS) RNU has not been shown to decisively improve overall survival (OS) compared to open surgery, MIS RNU has been associated with reduced hospital length of stay (LOS), blood transfusion requirements and improved recovery, which are important considerations when treating older patients...

OBJECTIVE: Which is superior, partial nephrectomy (PN) or radical nephrectomy (RN), for the treatment of complex renal tumours (RENAL or score ≥ 7)? METHODS: This systematic review and meta-analysis was conducted in accordance with the PRISMA statement. A systematic search of the literature published before November 2023 was conducted using Pubmed, Embase, Cochran, and Web of Science libraries. We included studies comparing perioperative and oncologic outcomes of partial nephrectomy and radical nephrectomy for complex renal tumors...

INTRODUCTION: Although cardiopulmonary bypass procedures remain a critical treatment option for heart disease, they come with risks, including hemorrhage. Tranexamic acid is known to reduce morbidity and mortality in surgical hemorrhage. OBJECTIVE: This study aimed to evaluate the efficacy of tranexamic acid, which is routinely used to treat hemorrhage, in decreasing the amount of intraoperative and postoperative drainage. METHOD: A total of 80 patients who underwent cardiac surgery with cardiopulmonary bypass were included in this retrospective study...
