Hemoglobin, tetramer, an excellent carrier. However, in body it converted into toxic dimers. Diacid or glutaraldehyde can crosslink hemoglobin polyhemoglobin (PolyHb) prevent its breakdown has been tested trials. A bovine approved routine surgical procedures South Africa Russia. Clinical trials human PolyHb hemorrhagic shock were effective but very slight increase non-fatal myocardial ischemia. could be due to number reasons. For those conditions ischemia-reperfusion, one would need carrier antioxidant properties. One approach remedy this prepared polyhemoglobin-catalase-superoxide dismutase (PolyHb-CAT-SOD). Another reason intracellular pCO 2 . We therefore added enhanced level carbonic prepare PolyHb-CAT-SOD-CA. result Carbonic Anhydrase CO transport Catalase Superoxide Dismutase functions.

Abstract Cardiac arrest is a critical emergency in cardiovascular medicine, requiring rapid, multidisciplinary interventions to enhance patient survival and neurological outcomes. This review explores the unique challenges of managing out-of-hospital (OHCA) in-hospital cardiac (IHCA), with focus on mechanical circulatory support (MCS) extracorporeal cardiopulmonary resuscitation for selected patients. While OHCA management should prioritize rapid transport specialized centres, IHCA may allow immediate, patient-tailored interventions. Post-cardiac syndrome adds complexity, often nuanced MCS escalation weaning. Standardized protocols, ethical considerations, further research are essential refine selection improve outcomes, ultimately advancing care.

The demand for organ transplantation has exceeded the global supply of available organs. Donation after circulatory death (DCD) is considered an effective method to solve disparity between and organs, by expanding donor pool. However, DCD organs experience long-term damage caused warm ischemia (WI) microthrombosis diffuse intravascular coagulation. Unfortunately, because concerns about post-transplantation complications, most high-risk are discarded, resulting in wasted medical resources economic losses. thrombolytic therapy before may dissolve improve microcirculation, increase use. Herein, we review current status potential value transplantation, summarize progress according preclinical clinical research, emphasize heterogeneity limitations studies that have some controversies associated with this therapy. Overall, role should not be overlooked. We anticipate combined machine perfusion will provide opportunity inferior-quality grafts, their becoming more widely safer thus solving urgent problem shortage.

Abstract Managing delivery of complex multidrug infusions in anesthesia and critical care presents a significant clinical challenge. Current practices relying on manual control infusion pumps often result unpredictable drug profiles dosing errors—key issues highlighted by the United States Food Drug Administration (FDA). To address these issues, we introduce SMART (synchronized‐pump management algorithms for reliable therapies) framework, novel approach that leverages low Reynolds number transport physics machine learning to accurately manage real‐time. is activated based Shafer (), non‐dimensional quantifies relative magnitude drug's therapeutic action timescale its within manifolds. useful when , where becomes rate limiting step achieving desired effects. When activated, monitors concentrations manifolds this information perform end‐to‐end using an ensemble deterministic deep reinforcement (RL) decision networks. Notably, RL networks employ differentially sampled split buffer architecture accelerates improves performance seamlessly combining predictions with experience during training. deployed standalone under simulated conditions outperformed state‐of‐the‐art protocols. This framework has potential revolutionize enhancing accuracy medication reducing cognitive workloads. Beyond care, ability multi‐liquid via will have important bearings manufacturing process control.

Background: Survival following cardiac arrest (CA) remains poor after conventional cardiopulmonary resuscitation (CCPR) (6–26%), and the outcomes extracorporeal (ECPR) are often inconsistent. Poor survival is a consequence of CA, low-flow states during CCPR, multi-organ injury, insufficient monitoring, delayed treatment causative condition. We developed new strategy to address these issues. Methods: This all-comers, multicenter, prospective observational study (69 patients with in- out-of-hospital CA (IHCA OHCA) prolonged refractory CCPR) focused on support, comprehensive repair, potential for cannulation treatment. Result: The overall rate at hospital discharge was 42.0%, favorable neurological outcome (CPC 1+2) 90 days achieved 79.3% survivors 1+2 33%). IHCA very (51.7%), as CPC (41%). OHCA 35% 28%. subgroup pre-hospital showed superior 57.1%. Conclusions: focusing repairing damage multiple organs appears improve findings should provide sound basis further research in this area.
