Acute Coronary Syndrome IV: Interprofessional Care

522
IntroductionThe management of Acute Coronary Syndrome (ACS) aims to minimize myocardial damage, preserve myocardial function, and prevent complications.Initial ManagementInpatient management involves continuous cardiac monitoring, preferably in an ICU, focusing on blood pressure, serum sodium, potassium, and creatinine levels, and urine output. Ongoing pharmacologic management is crucial for stabilizing the patient.Supplemental Oxygen: Administer supplemental oxygen if oxygen saturation is...

Vigilant monitoring for aneurysm rupture is essential for patients undergoing aortic surgery.Preoperative Nursing ManagementContinuously monitor the patient for manifestations of aneurysm rupture, such as pallor, weakness, tachycardia, hypotension, abdominal, back, groin, or periumbilical pain, changes in consciousness, and a pulsating abdominal mass. Regularly assess the patient's peripheral pulses.Instruct the patient to consume a clear liquid diet the day before surgery and administer...

Acute Coronary Syndrome I: Introduction

2.0K
Acute Coronary Syndrome (ACS) encompasses a spectrum of heart conditions caused by sudden obstruction of coronary arteries, typically resulting from the rupture of an atherosclerotic plaque and subsequent thrombus (blood clot) formation. This obstruction can lead to partial or complete blockage of blood flow, causing varying degrees of myocardial ischemia or infarction.ACS includes the following clinical entities:Unstable Angina (UA)Non-ST-Elevation Myocardial Infarction (NSTEMI)ST-Elevation...

    Summary

    Acute mesenteric ischemia (AMI) is a severe heart surgery complication. Non-occlusive mesenteric ischemia (NOMI) is frequent, with risk factors including age and low ejection fraction, leading to 100% mortality in this study.

    Area of Science:

    • Cardiovascular Surgery
    • Gastrointestinal Surgery
    • Critical Care Medicine

    Background:

    • Acute mesenteric ischemia (AMI) is a rare but severe complication following cardiac surgery.
    • Non-occlusive mesenteric ischemia (NOMI) is the most frequent type, often caused by reduced splenic blood flow, leading to intestinal damage and multi-organ failure.

    Purpose of the Study:

    • To identify risk factors and outcomes of non-occlusive mesenteric ischemia (NOMI) in patients undergoing open heart surgery with cardiopulmonary bypass.
    • To highlight the importance of early diagnosis and treatment of AMI in cardiac surgery patients.

    Main Methods:

    • Retrospective study of patients who underwent open heart surgery with non-pulsatile flow cardiopulmonary bypass.
    • Identified 4 cases of angiographically confirmed NOMI.

  • Superior mesenteric artery angiography was used for diagnosis when AMI was suspected based on clinical and laboratory findings.

    • Main Results:

    • Key risk factors included age over 70, LVEF < 35%, aortic clamping > 100 min, chronic kidney failure, and specific medications/interventions.
    • Clinical signs were nonspecific (hypoventilation, hypotension, oliguria, acidosis, leucocytosis).
    • All identified patients experienced 100% mortality despite medical treatment and intestinal resection.

    Conclusions:

    • AMI is a critical complication in cardiac surgery, necessitating awareness of risk factors.
    • Early suspicion, diagnosis, and prompt treatment are crucial for managing AMI.
    • The high mortality rate underscores the severity and challenges in treating NOMI post-cardiac surgery.
