Cardiomyopathy VII: Pre and Post Operative Nursing Management

29
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...

Cardiac emergencies are critical situations involving the heart that require immediate medical intervention to prevent severe complications or death. These emergencies often arise from underlying heart conditions that impair the heart's ability to function correctly.Types of Cardiac EmergenciesThe most common types of cardiac emergencies include Acute Coronary Syndrome (ACS), myocardial infarction (MI), cardiac arrest, and heart failure.Acute Coronary Syndrome (ACS)Acute Coronary Syndrome (ACS)...

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...

Summary

Gastrointestinal complications after cardiac surgery requiring emergency surgery have a 51% mortality rate. Obesity, high SOFA scores, and low platelets predict poor outcomes, aiding risk stratification.

Area of Science:

  • Cardiovascular Surgery
  • Gastrointestinal Surgery
  • Critical Care Medicine

Background:

  • Gastrointestinal complications following cardiac surgery necessitating emergency general surgery (EGS) are linked to significant morbidity and mortality.
  • Effective risk stratification and clinical decision-making can be improved by identifying predictors of 30-day mortality and preoperative laboratory-based futility thresholds.

Purpose of the Study:

  • To identify predictors of 30-day mortality in patients undergoing cardiac surgery who require EGS for gastrointestinal complications.
  • To establish intuitive preoperative laboratory-based futility thresholds for risk stratification.

Main Methods:

  • A single-center retrospective cohort study included adults aged 18-90 who underwent cardiac surgery between 2013-2023.
  • Patients requiring EGS for gastrointestinal complications during their index hospitalization were analyzed.
  • Multivariable logistic regression identified predictors of 30-day mortality and laboratory-based futility thresholds.

Main Results:

  • Of 95 patients, 30-day mortality was 51%, with ischemic bowel being the most common diagnosis (56%).
  • Nonsurvivors exhibited higher rates of obesity (BMI ≥ 30), elevated Sequential Organ Failure Assessment (SOFA) scores, and end-stage renal disease.
  • Key mortality predictors included SOFA ≥ 11.5 (aOR 3.2), BMI ≥ 30 (aOR 4.0), and platelet count < 100 × 10^3/μL (aOR 5.9).
  • Laboratory thresholds for 100% 30-day mortality: platelet count < 95 × 10^3/μL, WBC < 4.3 × 10^3/μL, lactate > 3.4 mmol/L, total bilirubin > 3.9 mg/dL.

Conclusions:

  • Patients requiring EGS intervention post-cardiac surgery face high 30-day mortality.
  • Elevated SOFA scores, obesity, and thrombocytopenia are critical predictors.
  • These findings support improved risk stratification and targeted management strategies.
