Summary
A new coagulation-based hemotherapy service improves patient care during cardiopulmonary bypass by providing rapid test results and a specialized transfusion algorithm, potentially reducing blood product use.
Area of Science:
- Cardiovascular Surgery
- Transfusion Medicine
- Laboratory Medicine
Background:
- Patients undergoing cardiopulmonary bypass (CPB) face coagulopathy risks.
- Delayed laboratory coagulation testing leads to empirical blood product use.
- A novel coagulation-based hemotherapy (CBH) service was established to address these issues.
Purpose of the Study:
- To describe the implementation of a clinical pathology consultation service (CBH).
- To utilize rapid turnaround time (TAT) coagulation testing.
- To develop and apply a transfusion algorithm for CPB patients.
Main Methods:
- Established a CBH service with a comprehensive coagulation testing menu.
- Located the laboratory near the operating room for rapid TAT.
- Implemented a transfusion algorithm monitored by a hemotherapy pathologist.
Main Results:
- The CBH service managed 105 cardiovascular surgeries.
- Achieved TAT of 15-30 minutes for key coagulation tests, significantly faster than standard 45-60 minutes.
- Preliminary data suggest reduced blood product usage and improved patient outcomes.
Conclusions:
- Successfully introduced a novel pathology consultation service (CBH).
- Rapid TAT coagulation testing and transfusion algorithms enhance CPB patient management.
- The CBH service offers a comprehensive approach to bleeding assessment.

Patients with hypertrophic cardiomyopathy (HCM) and left ventricular outflow tract (LVOT) obstruction who remain symptomatic despite optimal medical therapy may undergo a septal myectomy (Morrow procedure). This procedure involves excising a portion of the hypertrophied septum below the aortic valve using a heart-lung machine to improve blood flow through the LVOT. Effective preoperative and postoperative nursing management ensures successful patient outcomes, minimizes complications, and...

Pharmacologic intervention is crucial in treating cardiac arrest patients during ACLS or Advanced Cardiovascular Life Support. The ACLS algorithms guide the administration of specific drugs based on the patient's cardiac arrest rhythm, which includes pulseless ventricular tachycardia (VT), ventricular fibrillation (VF), asystole, and pulseless electrical activity (PEA).EpinephrineIndication: Epinephrine is the first-line drug for all cardiac arrest rhythms.Mechanism of Action: Epinephrine...

Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...

A pulmonary embolism occurs when a thrombus, amniotic fluid, tumor tissue, fat, or air embolus blocks one or more pulmonary arteries. Effective nursing management and patient education are crucial for improving outcomes and preventing recurrence.Nursing management starts with obtaining a comprehensive patient history, particularly noting any history of deep vein thrombosis (DVT). Assess for clinical manifestations, including dyspnea, chest pain, crackles, heart murmurs, and signs of right-sided...
