Cardiac Catheterization IV: Nursing Management

68
Nursing responsibilities before cardiac catheterization include:Assess for allergies and establish baseline health status.Before cardiac catheterization, assess the patient for allergies to contrast dye. Perform a comprehensive baseline assessment, including vital signs, heart and breath sounds, and a neurovascular assessment of the extremities, noting distal pulses, skin color, and temperature. Instruct the patient to fast for 8-12 hours before the procedure. Evaluate baseline laboratory...

Cardiomyopathy VII: Pre and Post Operative Nursing Management

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 Catheterization I: Pre-Procedure Overview

69
Cardiac catheterization is an invasive diagnostic technique used to identify and evaluate structural and functional diseases of the heart and major blood vessels. This technique diagnoses congenital heart disease, coronary artery disease, valvular heart disease, and coronary spasms and assesses ventricular function. It helps guide treatment decisions, including the need for revascularization procedures like percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) and...

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...

Alterations in Blood Pressure01:30

Alterations in Blood Pressure

1.3K
Alterations in blood pressure, such as hypertension (high blood pressure) and hypotension (low blood pressure), significantly affect human health. Understanding these conditions' classifications, causes, and symptoms is essential for effective management and treatment.
Hypertension (High blood pressure)
Hypertension occurs when blood pressure readings consistently exceed the normal range. It is diagnosed when systolic blood pressure (the top number, indicating pressure while the heart...

Area of Science:

  • Anesthesiology
  • Surgical Outcomes
  • Health Services Research

Background:

  • Intraoperative hypotension (IOH) is a critical concern during surgical procedures.
  • Understanding IOH incidence in Ambulatory Surgery Centers (ASCs) is essential for patient safety.
  • Previous literature has primarily focused on IOH in hospital settings.

Purpose of the Study:

  • To measure the incidence of intraoperative hypotension (IOH) in ambulatory surgery centers (ASCs).
  • To describe patient and procedural characteristics associated with IOH in ASCs.
  • To compare IOH incidence in ASCs with findings from academic hospital settings.

Main Methods:

  • Retrospective analysis of 16,750 patients undergoing non-emergent, non-cardiac surgery in 20 ASCs.
  • IOH was defined as mean arterial pressure (MAP) <65 mmHg for at least 15 cumulative minutes, per CMS MIPS criteria.
  • Secondary definitions included minutes of MAP <65 mmHg, area under MAP of 65 mmHg, and time-weighted average MAP <65 mmHg.

Main Results:

  • 30.9% of cases experienced IOH (MAP <65 mmHg for ≥15 min).
  • Higher IOH incidence was observed in younger adults (18-39 years; 36.2%), females (35.2%), and ASA physical status 2 patients (32.8%).
  • IOH increased with surgery length and was highest in high-complexity procedures (44.1%).

Conclusions:

  • A substantial occurrence of IOH was found in ASCs, comparable to hospital settings.
  • Hypotheses suggest potential clinician under-intervention or assumptions about patient tolerance.
  • Further research is needed to determine if IOH in ASCs is associated with adverse outcomes similar to hospital-based surgeries.
