Complications occurring in the postanesthesia care unit: a survey

Area of Science:

• Anesthesiology
• Patient Safety
• Surgical Outcomes

Background:

• Postanesthesia care units (PACUs) are critical for patient recovery after anesthesia.
• Identifying and quantifying complications in the PACU is essential for improving patient outcomes.
• Previous studies have highlighted the significance of PACU events on patient morbidity.

Purpose of the Study:

• To prospectively identify and quantify the incidence of complications occurring during the postanesthesia care unit (PACU) period.
• To determine the relationship between patient factors and the development of PACU complications.
• To analyze the impact of intraoperative and PACU events on overall patient morbidity.

Main Methods:

• A prospective study involving 18,473 consecutive patients admitted to a PACU at a university teaching hospital.
• Standardized collection forms were used to record intraoperative and PACU complications.
• Patient data, including ASA physical status, anesthetic technique, and surgical procedure type, were analyzed.

Main Results:

• The overall complication rate (intraoperative and PACU) was 26.7%, with a PACU complication rate of 23.7%.
• The most frequent PACU complications included nausea and vomiting (9.8%), need for upper airway support (6.9%), and hypotension (2.7%).
• Higher ASA physical status, longer anesthesia duration, emergency procedures, and specific surgical types (orthopedic, abdominal) were associated with increased PACU complication risk.

Conclusions:

• Postanesthesia care unit events represent a significant source of patient morbidity.
• Nausea, vomiting, and airway support are prevalent PACU complications requiring attention.
• Risk stratification using factors like ASA status and procedure type can help anticipate and manage PACU complications.
