Cardiomyopathy VII: Pre and Post Operative Nursing Management

226
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...

Area of Science:

  • Cardiovascular Surgery
  • Anesthesiology
  • Transfusion Medicine

Background:

  • Perioperative outcomes can be influenced by various factors, including the timing of surgical procedures.
  • Understanding temporal variations in patient management is crucial for optimizing surgical care.

Purpose of the Study:

  • To investigate the association between the time of day and perioperative outcomes.
  • Specifically, to examine intraoperative transfusion rates in adult cardiac surgery patients based on case start times.

Main Methods:

  • Retrospective observational study conducted at a single academic medical center.
  • Included adult patients undergoing cardiac surgery with cardiopulmonary bypass.
  • Multivariate logistic regression was used to analyze the association between case start time and transfusion probability.

Main Results:

  • A total of 1,421 cases were initially reviewed, with 1,220 matched for analysis.
  • The probability of receiving an intraoperative red blood cell transfusion significantly increased with later case start times (p=0.027).
  • No significant difference in transfusion probability was observed for plasma, cryoprecipitate, or platelets based on case start time.

Conclusions:

  • The rate of intraoperative blood product transfusion varies significantly with later case start times in scheduled cardiac surgery.
  • Timing of cardiac surgery may be a relevant factor influencing the need for red blood cell transfusions.
