Article Abstract
Introduction: Insufficient withdrawal duration of antithrombotics leads to excessive bleeding after major surgery. We hypothesize that intraoperative hemoadsorption (HA) can reduce postoperative allogeneic transfusion requirements and excessive bleeding events (EBE), without an increase in ischemic/thromboembolic events (ITE) in patients who have taken antithrombotics and undergone nonelective cardiac surgery.
Methods: A total of 460 patients admitted to our hospital from 2018 to 2022 were included in this study and divided into two groups: HA and non-HA. Because of the risk of bias due to differences in antithrombotic type, withdrawal duration, or basic coagulation function, propensity score matching was used for analyses.
Results: Out of 154 cases in the HA group, 144 pairs were successfully matched. No HA safety events such as hemolysis, hypotension, or device failure occurred. After matching, the two groups were found to be comparable in preoperative antithrombotic type, withdrawal duration, platelets and coagulation function, and demographic and perioperative characteristics. Although the HA group did not have a reduced incidence of EBE, this group exhibited significant decreases in the transfusion rate and volume, the incidence of ITE, acute kidney injury, and central nervous system injury.
Conclusions: For patients who have undergone nonelective cardiac surgery and taken antithrombotics, HA can simply and safely rebalance the postoperative coagulation system and have associations with reduced transfusion and postoperative ITE.

Prophylactic phenylephrine and norepinephrine infusions during caesarean delivery for non-reassuring fetal heart rate: A randomised noninferiority trial to assess neonatal outcome.

Background: Phenylephrine is recommended for the management of hypotension after spinal anaesthesia for women undergoing caesarean delivery. Norepinephrine, an adrenergic agonist with weak β-adrenergic activity, has been reported to have a more favourable haemodynamic profile than phenylephrine. However, there are concerns that norepinephrine may be associated with higher risk of fetal acidosis which can be serious in an already compromised foetus.

Objective: This study aimed to evaluate whether wait times for urgent or emergent operations cases differ between female and male attending surgeons.
Summary Background Data: Patients treated by female surgeons experience lower complication rates compared to those treated by male surgeons. The impact of surgeon gender on wait times remains underexplored.
Variation in mechanical circulatory support use for acute myocardial infarction cardiogenic shock.

Background: Cardiogenic shock (CS) is a leading cause of mortality following acute myocardial infarction (AMI). Some patients may require intra-aortic balloon pump (IABP) or percutaneous ventricular assist device (PVAD) placement; however, there is a paucity of standardised algorithms to guide the deployment of each device. The present study evaluated interhospital variation in the use of IABP and PVAD for AMI CS and identified institutional factors associated with hospital-level device preference.

Background: Optimization strategies, including weight loss, smoking cessation, and controlling blood glucose may delay ventral hernia surgery resulting in nonelective (ie, urgent or emergent) repair. Evidence on the risk factors influencing presentation that provide insight into who may be less amenable to optimization strategies are limited. This study evaluated the sociodemographic factors, insurance types, and medically optimizable factors associated with undergoing nonelective ventral hernia surgery.

Background: Acute pulmonary embolism (PE) is one of the most common causes of cardiovascular mortality in the United States. Significant variations in the management of various cardiovascular conditions have previously been reported, but this has been poorly elucidated for pulmonary embolism.
Methods: During 2016-2020, adult (≥ 18 years) nonelective admissions with PE, admitted to Northeast, Midwest, South, and West geographic regions were identified using the National Inpatient Sample.
