[Postoperative pulmonary complications: prophylaxis after noncardiac surgery]

Area of Science:

• Anesthesiology
• Critical Care Medicine
• Thoracic Surgery

Background:

• Postoperative pulmonary complications (PPCs) are a significant concern following major abdominal and thoracoabdominal surgeries.
• These complications contribute to increased intensive care unit (ICU) stays, elevated healthcare costs, and are a primary driver of early postoperative mortality.
• Postoperative hypoxemia affects 30-50% of patients even after uncomplicated procedures, highlighting the vulnerability of respiratory function.

Purpose of the Study:

• To review the incidence, impact, and management strategies for postoperative pulmonary complications.
• To emphasize the importance of a structured approach to prevent and mitigate respiratory issues in surgical patients.
• To highlight key complications such as pulmonary edema, atelectasis, pneumonia, hypoventilation, and aspiration.

Main Methods:

• Literature review of studies focusing on pulmonary complications after upper abdominal and thoracoabdominal surgery.
• Analysis of factors contributing to postoperative hypoxemia and acute respiratory failure.
• Evaluation of preventive and therapeutic interventions.

Main Results:

• PPCs are common, leading to prolonged ICU stays and increased mortality.
• Acute respiratory failure, a severe complication, has a mortality rate ranging from 10% to 60% depending on severity.
• Key complications include pulmonary edema, atelectasis, pneumonia, hypoventilation, and aspiration.

Conclusions:

• Preoperative optimization of patient condition is crucial for reducing complication rates.
• A stepwise approach to postoperative prophylaxis, including respiratory support and monitoring, is recommended.
• Early patient mobilization plays a vital role in decreasing the incidence and severity of PPCs.
