Implication

Prospective cohort study reveals a 1.3% incidence of critical respiratory events after general anesthesia, highlighting key medication and surgical risk factors.

Key Points

To determine the incidence of unanticipated critical respiratory events in the postanesthesia care unit and identify associated patient, surgical, and anesthetic risk factors.
Prospective cohort study collecting preoperative, intraoperative, and postoperative data from 24,157 consecutive patients receiving general anesthesia over a 33-month period.
A critical respiratory event (CRE) was defined as unanticipated hypoxemia, hypoventilation, or upper-airway obstruction requiring active clinical intervention.
Independent risk factors were evaluated using logistic regression analysis alongside tracking of secondary morbidities and recovery duration.
Critical respiratory events occurred in 1.3% of patients (hypoxemia 0.9%, hypoventilation 0.2%, upper-airway obstruction 0.2%).
Significant anesthetic risk factors (P < 0.05) included thiopental induction compared to propofol (odds ratio [OR] 2.5), atracurium ≥ 0.25 mg·kg⁻¹·h⁻¹ (OR 2.2), preoperative sedatives (OR 2.0), fentanyl > 2.0 µg·kg⁻¹·h⁻¹ alone (OR 1.9), opioid premedication (OR 1.8), and fentanyl combined with morphine (OR 1.6).
Patient age > 60 years, male sex, diabetes, obesity, emergency surgery, and operative duration > 4 hours increased risk (P < 0.05), with CRE occurrence tied to prolonged recovery, elevated cardiac events, and intensive care admissions (P < 0.01).
