Observational StudySNAP II index: an alternative to the COMFORT scale in assessing the level of sedation in mechanically ventilated pediatric patients.
Sedation monitoring is essential in pediatric patients on ventilatory support to achieve comfort and safety. The COMFORT scale was designed and validated to assess the level of sedation in intubated pediatric patients. However, it remains unreliable in pharmacologically paralyzed patients. ⋯ Previous studies suggested that the SNAP II index is a reliable and sensitive indicator of the level of consciousness in adult patients. Despite its potential, no data are currently available in the pediatric critically ill population on ventilatory support. This is the first pilot study assessing the potential application of the SNAP II index in critically ill pediatric patients by comparing it to the commonly used COMFORT scale.

Fluid management in critical illness has undergone extensive reevaluation in the past decade. Since a significant percentage of critically ill patients develop acute kidney injury (AKI), optimal fluid management is even more paramount to prevent the ill effects of either underhydration or overhydration. ⋯ A number of prospective randomized trials are planned to provide an adequately powered assessment of the effect of EGDT or earlier renal replacement therapy initiation in patients with, or at risk for AKI. The aim of this analytical review is to use existing clinical and physiological studies to support a 3-phase model of fluid management in the critically ill patient with AKI.

Accuracy of noninvasive and continuous hemoglobin measurement by pulse co-oximetry during preoperative phlebotomy.
In recent years, the continuous noninvasive hemoglobin measurement has been offered by devices using advanced pulse oximetry technology. Accuracy has been established in healthy adults as well as in surgical and intensive care unit patients but not in the setting of acute hemorrhage. In this study, we evaluated the accuracy of such a device in the clinical setting of preoperative phlebotomy thereby mimicking a scenario of acute blood loss. ⋯ The current study demonstrates that the accuracy of continuous, noninvasive hemoglobin measurement was not affected by acute blood loss simulated by preoperative phlebotomy. Although the device provided a clinically acceptable correlation with the actual hemoglobin value and offers the value of a continuous trend monitor, given the precision of the device, it does not appear that actual transfusion decisions can be based on the device alone.
