Comparative Study
Validation of noninvasive hemoglobin measurements using the Masimo Radical-7 SpHb Station.
Hemoglobin levels must be obtained through blood draws, which are invasive, time-consuming, and provide only 1 data point at a time rather than continuous measurements. The Masimo Radical-7 SpHb Station (Masimo Corporation, Irvine, CA) has been shown by its manufacturers to provide accurate noninvasive hemoglobin measurements in physiologically normal patients. The objective of this study was to validate noninvasive hemoglobin measurements using the Masimo Radical-7 device. ⋯ Noninvasive hemoglobin monitoring is a new technology that correlated with laboratory values and supports the continued study of noninvasive hemoglobin monitoring.

Comparative Study
Trauma induces a hypercoagulable state that is resistant to hypothermia as measured by thrombelastogram.
The aim of this study was to test the hypothesis that severely injured trauma patients would be hypercoagulable compared with controls measured by thromboelastography and that this hypercoagulability would persist over a broad range of temperatures. ⋯ Severely injured patients are more hypercoagulable than controls throughout a broad range of temperature. Decreasing temperature has a greater effect on coagulation in controls compared with patients.

Determinants of postoperative hypocalcemia in vitamin D-deficient Graves' patients after total thyroidectomy.
The etiology of postoperative hypocalcemia after total thyroidectomy appears to be multifactorial, that is, postoperative transient hypoparathyroidism, low 25-hydroxy vitamin D (25-OHD) concentrations, aging, and hyperthyroidism with increased bone turnover. Our aim was to evaluate the factors responsible for postoperative hypocalcemia in euthyroid vitamin D-deficient/insufficient Graves patients who underwent total thyroidectomy at our institution. ⋯ In Graves patients with vitamin D deficiency/insufficiency, postoperative (transient) hypoparathyroidism is the most significant parameter to determine the development of postoperative hypocalcemia.

The aim of this study was to examine the implementation and sustainability of checklist use among procedural-based specialties in a pediatric hospital and to survey perceptions of checklist efficacy among staff members and physicians. ⋯ The implementation of a procedural checklist can be sustained across specialties with high compliance. Off-hours utilization remains problematic. Perceptions of checklist efficacy are disparate among roles in the operating room.
