Cardiac arrest may occur intraoperatively at any time. The purpose of this article is to help the reader recognize and assist in the management of an intraoperative cardiac arrest. Patients who are at risk for cardiac arrest in the OR are identified and different types of pulseless arrythmias are identified. Roles of perioperative personnel are suggested and documentation during the code is discussed.

Increased thrombotic events that occur in up to one-third of patients with COVID-19 are predominantly pulmonary emboli (PE), which are associated with higher severity and increased mortality. Acute PE should therefore be one of the main differential diagnoses among patients with hemodynamic instability. Early treatment of such a condition with systemic thrombolysis remains the first line of treatment especially in patients with COVID-19, which hinders further invasive intervention.

Background: Selecting an appropriate cannula size is crucial for achieving an adequate extracorporeal membrane oxygenation (ECMO) flow rate. However, the association between ECMO cannula size and the prognosis of patients with out-of-hospital cardiac arrest (OHCA) has not been fully elucidated. We examined the associations between ECMO cannula size and neurological outcomes and survival at discharge in patients with OHCA who received ECMO.

Cardiologists have analyzed daily patterns in the incidence of sudden cardiac death to identify environmental, behavioral, and physiological factors that trigger fatal arrhythmias. Recent studies have indicated an overall increase in sudden cardiac arrest during daytime hours when the frequency of arrhythmogenic triggers is highest. The risk of fatal arrhythmias arises from the interaction between these triggers-such as elevated sympathetic signaling, catecholamine levels, heart rate, afterload, and platelet aggregation-and the heart's susceptibility (myocardial substrate) to them.

Background: Prior studies have proposed defibrillator biosignal algorithms which characterize cardiac arrest rhythm and physiologic status. We evaluated whether a novel, individualized resuscitation strategy that integrates multiple ECG and impedance-based algorithms could reduce CPR interruptions and better align rescuer actions with patient-specific physiology.
Methods: In a retrospective cohort of ventricular fibrillation out-of-hospital cardiac arrests, observed rescuer actions (rhythm analysis, shock delivery, pulse checks, and drug therapy) were compared to hypothetical actions recommended by the proposed individualized strategy.
