End-tidal carbon dioxide monitoring improves patient safety during propofol-based sedation for breast lumpectomy: A randomised controlled trial

BACKGROUND The use of sedation is becoming more commonplace. Although pulse oximetry is a standard monitoring procedure during sedation, it cannot accurately detect early hypoventilation. End-tidal carbon dioxide (EtCO2) monitoring can be an earlier indicator of airway compromise; however, the existing literature is limited to a few studies with varying outcomes. OBJECTIVES To evaluate whether EtCO2 monitoring decreases the incidences of CO2 retention and apnoeic events in propofol-based sedation. DESIGN Randomised controlled study. SETTING A tertiary hospital. PATIENTS Two hundred women (aged 18 to 65 years, ASA physical status 1 or 2) who were scheduled for breast lumpectomy between June 2017 and August 2017. INTERVENTIONS Patients were allocated randomly to receive either standard monitoring or standard monitoring and EtCO2 monitoring. MAIN OUTCOME MEASURES The primary outcome was the incidence of CO2 retention. The secondary outcomes were the number of actions taken to restore ventilation, variations in PaCO2 and pH, the frequency of apnoea and the recovery time. RESULTS CO2 retention occurred significantly less often in the EtCO2 monitoring group (10 vs. 87%; P
