The effect of coughing at extubation on oxygenation in the post‐anaesthesia care unit

Summary We prospectively studied 84 patients to investigate whether there is a relationship between coughing during emergence and tracheal extubation, and impaired oxygenation in the post‐anaesthesia care unit. Our primary outcome measure was a change in the alveolar‐arterial oxygen partial pressure...

Description
Summary:Summary We prospectively studied 84 patients to investigate whether there is a relationship between coughing during emergence and tracheal extubation, and impaired oxygenation in the post‐anaesthesia care unit. Our primary outcome measure was a change in the alveolar‐arterial oxygen partial pressure gradient ((A‐a)DO2) between time A (during general anaesthesia) and time B (1 h after extubation). Patients demonstrated a worsening of oxygenation with mean (SD) (A‐a)DO2 increasing from 7.5 (5.2) kPa at time A to 13.9 (4.2) kPa at time B (p
