Risk Factors for Prolonged Mechanical Ventilation and Delayed Extubation Following Bimaxillary Orthognathic Surgery:...

Area of Science:

• Anesthesiology
• Oral and Maxillofacial Surgery
• Critical Care Medicine

Background:

• Bimaxillary orthognathic surgery carries significant risks of postoperative airway complications.
• Current guidelines lack clear recommendations for immediate postoperative monitoring and follow-up.
• Effective risk stratification is crucial for patient safety.

Purpose of the Study:

• To identify independent risk factors associated with prolonged mechanical ventilation and delayed extubation.
• To inform clinical practice and improve patient outcomes after bimaxillary orthognathic surgery.

Main Methods:

• A single-center retrospective cohort study analyzed data from 195 patients undergoing bimaxillary surgery.
• Clinical data, including baseline characteristics and perioperative factors, were evaluated.
• Multivariable analysis identified predictors of prolonged mechanical ventilation.

Main Results:

• Male sex, benzodiazepine premedication, and longer surgical duration were associated with prolonged mechanical ventilation.
• Total intravenous anesthesia was linked to shorter ventilation times.
• American Society of Anesthesiologists Physical Status Classification System III or higher patients represented 4.6% of the cohort.

Conclusions:

• Benzodiazepine premedication, male sex, and surgical duration are potential independent risk factors for delayed extubation.
• These factors should be considered in the perioperative management of patients undergoing bimaxillary surgery.
• Further research may refine risk assessment and management strategies.
