To systematically evaluate anesthesiology resident and attending perceptions of preoperative planning conversations (POPCs) and to generate understanding for improving the educational and clinical value of this practice. ⋯ Significant discrepancies exist between how anesthesia attendings and residents perceive the purpose of the POPC, with trainees less likely to view the POPC as having clinical value and neither group perceiving the conversation as a very useful educational tool. The results highlight the need to reexamine the value of the daily POPC as a deliberate educational practice to meet expectations of both trainees and attendings.

Observational Study
Association between intraoperative body temperature and postoperative delirium: A retrospective observational study.
The effect of perioperative body temperature derangement on postoperative delirium remains unclear. This study aimed to evaluate the association between intraoperative body temperature and postoperative delirium in patients having noncardiac surgery. ⋯ Intraoperative hypothermia (even mild hypothermia) was significantly associated with an increased risk of postoperative delirium.

Observational Study
Feasibility of intraoperative continuous glucose monitoring: An observational study in general surgery patients.
Perioperative hyperglycemia is associated with adverse outcomes in surgical patients, and major societies recommend intraoperative monitoring and treatment targeting glucose <180-200 mg/dL. However, compliance with these recommendations is poor, in part due to fear of unrecognized hypoglycemia. Continuous Glucose Monitors (CGMs) measure interstitial glucose with a subcutaneous electrode and can display the results on a receiver or smartphone. Historically CGMs have not been utilized for surgical patients. We investigated the use of CGM in the perioperative setting compared to current standard practices. ⋯ Both Dexcom G6 and Freestyle Libre 2.0 CGMs were able to be utilized and functioned well if no sensor error occurred at time of initial warmup. CGM provided more glycemic data and further characterized glycemic trends more than individual BG readings. Required time of CGM warm up was a barrier for intraoperative use as well as unexplained sensor failure. CGMs had a fixed warm of time, 1 h for Libre 2.0 and 2 h for Dexcom G6 CGM, before glycemic data obtainable. Sensor application issues did not occur. It is anticipated that this technology could be used to improve glycemic control in the perioperative setting. Additional studies are needed to evaluate use intraoperatively and assess further if any interference from electrocautery or grounding devices may contribute to initial sensor failure. It may be beneficial in future studies to place CGM during preoperative clinic evaluation the week prior to surgery. Use of CGMs in these settings is feasible and warrants further evaluation of this technology on perioperative glycemic management.
