Assessment of Intraoperative Nursing Safety Precautions for Open Heart Surgery Patients on Cardiopulmonary Bypass Machine

Study Overview

Brief Summary
-----------------
Assessment of intraoperative nursing safety precautions for open heart surgery patients on cardiopulmonary bypass machine.

Detailed Description
-----------------
Coronary artery bypass grafts surgery (CABG) can be performed either with cardiopulmonary bypass (CPB), which exposes the blood to a non-physiological environment, or on beating heart without CPB support. One of the most challenging aspects of coronary artery bypass grafting surgery is the management of high-risk patients and management of possible complications due to cardiopulmonary bypass machine to achieve acceptable morbidity, mortality, and quality of life Nursing safety precautions during cardiopulmonary bypass surgery begins with the perfusionists and critical care nurses experience and knowledge of all the possible errors that may occur. This knowledge fosters the anticipation of problems and promotes vigilance safety precautions for prevention of possible complications which may occur as a result of cardiopulmonary bypass machine. Advances in cardiac surgery have been possible due to the development of cardiopulmonary bypass machine. Cardiopulmonary bypass machine is a form of extracorporeal circulation whose function is circulatory and respiratory support along with temperature management to facilitate surgery on the heart and great vessels. The first successful human cardiac surgery using CPB was performed by John Gibbon in 1952 for repair of the atrial septal defect. Complications that occur as a result of cardiopulmonary bypass machine in cardiac surgery patients includes mechanical and systemic complications, mechanical complications such as bleeding, oxygenator failure, pump malfunction, clotting in the circuit, tubing rupture, gas supply failure and electrical failure. Systemic complications include qualitative and quantitative platelet dysfunction. Inflammatory response and hypotension can cause acute kidney injury. Risk factors are prolonged bypass time, sepsis and diabetes. cerebral injury ranges from cognitive dysfunction to stroke. Acute respiratory distress syndrome can be present due to the effects of CPB. Nursing safety precautions related to cardiac surgery with cardiopulmonary bypass machine were written with collaboration from the Society of Cardiovascular Anesthesiologists, and an update to these safety precautions that have collaborated on nursing safety precautions for anticoagulation, as Clotting on cardiopulmonary bypass is life-threatening. Temperature management, acid base balance management, monitoring on cardiopulmonary bypass, ultra-filtration during and after CPB removes inflammatory mediators and weaning management. These safety precautions provide professional nurses with actionable evidence informed by expert opinion, to achieve acceptable morbidity, mortality, and quality of life.

| --- | --- | --- |
| assessment of nursing safety precautions for cardiac surgery patients on cardiopulmonary bypass machine | This part was including assessment of nursing safety precautions during surgery for patients on cardiopulmonary bypass machine using scoring system. Nursing safety precautions consists of four main items each item divided into steps, each step takes a score ranging from 0 to 2, minimum score is 0 (not apply), medium score is1 (need improve) and maximum score is 2 (well done). Total steps in four items are 45 steps their total score is 90, scoring system transformed into percent:( < 85% unsatisfactory), (>= 85% satisfactory). | baseline |
