Randomized Controlled Trial Comparative Study Observational Study
Accuracy of blood glucose measurements using the NOVA StatStrip® glucometer during cardiac surgery: a prospective observational study.
The Nova StatStrip® Glucose Hospital Meter System (Nova Biomedical, Waltham, MA, USA) is United States Food and Drug Administration approved for point-of-care use in critically ill patients, but its use during cardiac surgery has not been evaluated. In this study, we compare glucose values obtained during cardiac surgery by StatStrip® with values obtained by a blood gas analyzer. ⋯ Arterial blood glucose measurement by StatStrip was accurate before CPB, but lacked accuracy during and after CPB. Glucose values should be interpreted with caution when intensive glucose control protocols are being used during cardiac surgery.

Observational Study
Anatomical evaluation of the extent of spread in the erector spinae plane block: a cadaveric study.
The erector spinae plane (ESP) block is an interfascial analgesic technique first described as an alternative for pain control at the thoracic level. The objective of this observational study was to determine the anatomical spread of dye following a T7 ESP block in a cadaveric model. ⋯ The results suggest that the ESP block reaches a wide range of the posterior rami of spinal nerves without diffusion into the paravertebral space or involvement of the anterior rami.

Anemia is highly prevalent in the colorectal surgery population, affecting 30-70% of patients. Anemia is associated with significant morbidity and mortality; however, there is a lack of evidence on how much anemia impacts healthcare costs. This study aims to determine the hospital cost of index surgical admission, postoperative length of stay, and transfusion rate associated with preoperative anemia in elective major colorectal surgery. ⋯ Over 2,600 CAD per index surgical admission is attributable to preoperative anemia. Preoperative interventions with per patient cost of less than 2,600 CAD could be cost effective at the hospital level.
