Identifying predictors of poor postoperative outcomes is crucial for planning personalized pain treatments. The aim of this study was to examine pain outcomes using cluster analysis in N = 2678 patients from the PAIN-OUT registry at first postoperative day. ⋯ Improvement of postoperative pain requires assessment methods that go beyond pain intensity scores. We perform a cluster analysis among PAIN-OUT patients that revealed a cluster of vulnerable postoperative patients, using a novel composite measure of postoperative outcomes: the factor scores of the International Pain Outcomes Questionnaire. By changing the focus from pain intensity to multidimensional pain outcomes, male gender and number of comorbidities appeared as new risk factors for worse postoperative outcomes. The study also identified procedures that require urgent quality improvements.

Randomized Controlled TrialChanges in lung aeration and respiratory function after open abdominal surgery: a quantitative magnetic resonance imaging study.
Atelectasis is one of the most common respiratory complications in patients undergoing open abdominal surgery. Peripheral oxygen saturation (SpO2 ) and forced vital capacity (FVC) are bedside indicators of postoperative respiratory dysfunction. The aim of this study was to describe the changes in lung aeration, using quantitative analysis of magnetic resonance imaging (MRI) and the diagnostic accuracy of SpO2 and FVC to detect postoperative atelectasis. ⋯ SpO2 and FVC correlated with the amount of postoperative non-aerated lung volume, showing acceptable diagnostic accuracy in bedside detection of postoperative atelectasis.

Situational Awareness of Opioid Consumption: The Missing Link to Reducing Dependence After Surgery?
A tool for collecting and analyzing morphine milligram equivalents (MMEs) can be used to overcome barriers to situational awareness around opioid utilization in the setting of multimodal pain management. Our software application (App) has facilitated data collection, analysis, and benchmarking in a manner that is not logistically feasible using manual methods. Real-time postoperative tracking of MME over the course of an episode of care can be prohibitively labor-intensive, and teams must have practical strategies to overcome this obstacle. In view of the link between the magnitude of opioid prescriptions at discharge and persistent opioid use after cardiac surgery, we believe that improving situational awareness among the patient care team is a vital first step in reducing opioid dependence after cardiac surgery.

Elevated perioperative heart rate potentially causes perioperative myocardial injury because of imbalance in oxygen supply and demand. However, large multicenter studies evaluating early postoperative heart rate and major adverse cardiac and cerebrovascular events (MACCEs) are lacking. ⋯ More research is needed to assess the usefulness of heart rate measurement in patients after CABG.
