Hemostatic agents: a guide to safe practice for perioperative nurses
AORN Journal
|August 1, 2014
Summary
Perioperative hemostasis involves managing bleeding with agents that aid clotting. Understanding hemostatic agents, their uses, and limitations is crucial for nurses to optimize patient care and reduce risks.
Area of Science:
- Anesthesiology
- Surgical Nursing
- Pharmacology
Background:
- Effective perioperative hemostasis is vital for managing bleeding during invasive procedures.
- Over 50 hemostatic products exist, with more in development, necessitating informed clinical choices.
- Perioperative nurses require comprehensive knowledge of hemostatic agents.
Purpose of the Study:
- To provide an overview of perioperative hemostasis and available hemostatic agents.
- To educate perioperative nurses on the actions, properties, applications, and limitations of hemostatic agents.
- To discuss the normal coagulation process, blood product management, financial implications, and complications associated with hemostatic agents.
Main Methods:
- Review of the normal coagulation cascade (clotting process).
- Analysis of blood product management and strategies to minimize their use.
- Examination of financial aspects and clinical applications of hemostatic agents.
Main Results:
- Detailed explanation of the body's natural clotting cascade.
- Discussion on the rationale for reducing blood product transfusion.
- Overview of various hemostatic agent categories, indications, and potential complications.
Conclusions:
- Perioperative nurses must understand diverse hemostatic agents for effective bleeding management.
- Informed use of hemostatic agents can improve patient outcomes and potentially reduce healthcare costs.
- Knowledge of hemostatic agents, their mechanisms, and risks is essential for safe surgical practice.

Hemostasis is a crucial process that prevents excessive blood loss from damaged blood vessels. It involves various mechanisms such as vasoconstriction, platelet adhesion and activation, and fibrin formation. The importance of each mechanism depends on the type of vessel injury. In contrast, thrombosis is the abnormal formation of a blood clot within the blood vessels, leading to potential complications if the clot obstructs blood flow. Thrombosis can be caused by increased coagulability of the...

Nursing management begins with a thorough assessment of the patient's health history. Key factors include trauma to veins, peripherally inserted central catheters, varicose veins, recent pregnancy or childbirth, surgery, bacteremia, prolonged bed rest, atrial fibrillation, COPD, heart failure, cancer, coagulation disorders, myocardial infarction, spinal cord injury, stroke, prolonged travel, recent bone fractures, and dehydration.

Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...

01:05Introduction to Hemostasis
13.9K
Hemostasis is a complex physiological process that prevents excessive bleeding when a blood vessel is injured. It's crucial for maintaining the integrity of the circulatory system, as it ensures that our blood remains fluid while still within the vascular network and yet clots to prevent blood loss upon vessel injury.
The three phases of hemostasis involve many clotting factors present in plasma and several substances released by platelets and injured tissue cells. It is a fast, localized,...

01:20Extrinsic and Intrinsic Pathways of Hemostasis
10.8K
Blood clotting or coagulation involves extrinsic and intrinsic pathways, which ultimately merge into the common pathway, forming a fibrin clot.
The Extrinsic Pathway
The extrinsic pathway of coagulation is typically initiated by tissue damage that exposes blood to tissue factor (TF), a protein released by the damaged tissue cells outside the blood vessels—this interaction with TF triggers biochemical reactions involving specific clotting factors. The key player here is Factor VII, which...

Oral anticoagulants are vital tools in preventing and treating blood clotting disorders. This diverse class of medications can be categorized as vitamin K antagonists, exemplified by warfarin, and direct thrombin inhibitors (DTIs), such as dabigatran, as well as factor Xa inhibitors, including rivaroxaban.
Warfarin, a prominent vitamin K antagonist family member, exerts its effect by inhibiting the enzyme VKORC1 (vitamin K epoxide reductase complex 1). By hindering this enzyme, warfarin...
