Noncardiothoracic nonobstetric surgery in mild-to-moderate pulmonary hypertension
The European Respiratory Journal
|November 10, 2009
Summary
Managing anesthesia for patients with pulmonary arterial hypertension undergoing surgery is complex. Complications were frequent (29%), especially in emergencies, but survivors showed stable long-term outcomes.
Area of Science:
- Anesthesiology
- Cardiology
- Pulmonology
Background:
- Pulmonary arterial hypertension (PAH) poses significant anesthetic challenges.
- Limited data exists on managing PAH patients undergoing noncardiothoracic, nonobstetric surgery.
Purpose of the Study:
- To review anesthetic management and outcomes of PAH patients undergoing surgery.
- To identify perioperative complications and risk factors in this population.
Main Methods:
- Retrospective review of 28 PAH patients undergoing major or minor surgery between 2000-2007.
- Analysis of perioperative complications, mortality, and long-term outcomes (NYHA class, 6-min walk, hemodynamics).
Main Results:
- 7% perioperative mortality; 29% experienced complications, primarily related to PAH.
- Complications were higher in emergency (100%), major (p=0.008), and long (p=0.003) surgeries.
- No significant long-term deterioration observed in survivors up to 12 months post-op.
Conclusions:
- Despite optimal management, perioperative complications are common in non-severe PAH patients undergoing surgery.
- Emergency and major surgeries, along with prolonged operative times, increase complication risk.
- Survivors demonstrate stable clinical and hemodynamic status post-operatively.

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...
01:30Pulmonary Hypertension: Classification and Pathogenesis
Pulmonary hypertension (PH) is a severe health condition in which the mean pulmonary arterial pressure increases to 25 mmHg or more, even when the body is at rest. This high pressure in the blood vessels that transport blood from the heart to the lungs can cause various symptoms, including shortness of breath, can lead to right heart failure, and significantly affect the overall quality of life.
There are various classifications for PH, each relating to different underlying causes and also...

Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...

Mitral stenosis, a condition marked by the narrowing of the mitral valve, necessitates an integrated approach for effective management. This approach includes preventative measures, medical therapy, and surgical interventions to reduce symptoms and prevent complications.PreventionPrevention of mitral stenosis primarily focuses on reducing the incidence of bacterial infections, particularly streptococcal infections, which can lead to rheumatic fever and subsequent valvular damage. Timely...

Pneumothorax is a medical condition defined by the buildup of air in the pleural space between the lungs and the chest wall. This accumulation of air can lead to partial or complete lung collapse, resulting in a range of clinical manifestations. Understanding the clinical presentation and effective management strategies is crucial for healthcare professionals in providing timely and appropriate care to individuals with pneumothorax.

Managing cardiomyopathy involves addressing underlying or precipitating causes, treating heart failure with medications, and implementing dietary changes and a balanced exercise and rest regimen.Lifestyle ModificationsCardiomyopathy patients should adopt a low-sodium diet to reduce fluid retention and manage heart failure. A personalized exercise and rest plan helps maintain physical fitness without overstraining the heart. Avoiding alcohol and tobacco is essential to prevent further damage to...
