Waking up in pain: an infographic

Abstract

In this prospective cohort study Rasmussen and colleagues reported their findings of 3,702 patients who underwent a variety of surgeries and found that 20% of patients reported moderate or severe pain immediately following surgery until 15 minutes after postanesthesia care unit arrival. The study included 31 public hospitals in Denmark, Greenland, and the Faroe Islands over a 5day period. Risk factors for higher pain levels included female sex, younger age, preoperative pain, daily opioid use, and major surgical procedures. The authors found postoperative nausea and vomiting occurred in only 5% of cases with female sex again being identified as a risk factor, consistent with prior studies. Finally, a greater proportion of patients who were sedated in the operating room had pain in the postanesthesia care unit versus nonsedated patients (11 versus 8%; p=0.008). This study illustrates that early control of postoperative pain remains a challenge.
