Attempts to reduce respiratory complications following upper abdominal operations

Area of Science:

• Anesthesiology
• Pulmonology
• Surgical Critical Care

Background:

• Post-operative respiratory complications are common after upper abdominal surgery.
• These complications can lead to increased morbidity and mortality.

Purpose of the Study:

• To assess respiratory complications in patients undergoing upper abdominal surgery.
• To evaluate the effectiveness of warm, humidified air in decreasing the frequency of these complications.

Main Methods:

• A study involving 85 patients following upper abdominal surgery.
• Intervention group received warm, humidified air.
• Control group did not receive the intervention.
• Assessment of respiratory symptoms (cough, sputum) and physical signs.
• Measurement of arterial oxygen tension (PaO2) at various post-operative time points.

Main Results:

• Patients receiving warm, humidified air showed a significant decrease in cough, sputum, and abnormal chest physical signs.
• Arterial oxygen tension was significantly higher in the intervention group on postoperative days 1 and 3.
• PaO2 in the intervention group remained above 95% of pre-operative levels from day 1 to day 5.

Conclusions:

• Warm, humidified air is an effective method for reducing post-operative respiratory complications after upper abdominal surgery.
• The intervention positively impacts gas exchange, maintaining arterial oxygen tension.
