Effect of Deep Hypothermia (18°C) on Dioxygen Metabolism During Pulmonary Thromboendarterectomy Surgery.
The aim of this physiological pilot study was to investigate the effect of deep hypothermia on oxygen extraction (OE) and consumption (VO2) in normothermic conditions (36-37°C), and at different stages of cooling: 30°C, 25°C, and 18°C. ⋯ There were VO2 and OE decreases of more than half their baseline values at 18°C. Given that metabolic needs are essentially supplied by dissolved O2 during cooling from 30°C to 18°C, the authors suggest that PaO2 should be increased during the period of cooling and/or deep hypothermia to prevent hypoxia.

Comparative Study Observational StudyA Retrospective Comparative Study of the Frequency of Hypotension in Pediatric Cardiac Catheterization under General Anesthesia: Remimazolam versus Sevoflurane.
To compare the incidence of hypotension between remimazolam and sevoflurane under general anesthesia for cardiac catheterization in patients with congenital heart disease. ⋯ Remimazolam was not associated with a lower incidence of hypotension compared to sevoflurane during pediatric cardiac catheterization for congenital heart disease while maintaining significantly higher blood pressure overall.

Insights Into Perioperative Hypertension Management in Europe: Results From a Survey Endorsed by the European Association of Cardiothoracic Anaesthesiology and Intensive Care (EACTAIC).
Perioperative blood pressure control is crucial to ensure organ perfusion and avoid adverse events. However, no consensus on blood pressure targets is available. This study was designed to gain insights into current European perioperative hypertension management practices. ⋯ Perioperative SBP targets above 140 mmHg are uncommon among respondents, who predominantly target SBP values between 120 and 140 mmHg. The choice of intravenous antihypertensives is based on their manageability and user experience, and titratable control is the most appreciated characteristic.

Observational StudyAssociation Between Red Cell Distribution Width and Liver Injury after Cardiac and Aortic Aneurysm Surgery with Cardiopulmonary Bypass.
This study aimed to investigate the association between preoperative red blood cell distribution width (RDW) levels and liver injury (LI) after cardiac surgery, to highlight RDW's usefulness in the early identification and intervention for patients at high risk of LI. ⋯ Preoperative RDW levels are significantly associated with postoperative LI. RDW could serve as a significant useful marker for early detection and intervention in patients at high risk of LI, thereby potentially improving patient outcomes.

Frailty Is Associated With Increased Care Dependence in Patients Following Major Vascular Surgery.
To assess if frailty scoring can predict increased frailty and care dependence requiring a change in living situation in patients with peripheral artery disease (PAD) following major vascular surgery. ⋯ Frail patients with PAD undergoing major vascular surgery are at significant risk of functional decline, necessitating a change in living situation to meet their increased care needs. This increased care dependence persisted 6 months following discharge.
