Observational StudyEvaluation of sedatives, analgesics, and neuromuscular blocking agents in adults receiving extracorporeal membrane oxygenation.
The objective of this study was to evaluate the use of sedative, analgesic, and neuromuscular blocking agents (NMBAs) in patients undergoing extracorporeal membrane oxygenation (ECMO) support. ⋯ Patients received relatively low doses of sedatives and analgesics while at a light level of sedation on average. Patients rarely required neuromuscular blockade.

Valproate for agitation in critically ill patients: A retrospective study.
The purpose was to describe the use of valproate therapy for agitation in critically ill patients, examine its safety, and describe its relationship with agitation and delirium. ⋯ Valproate therapy was associated with a reduction in agitation, delirium, and concomitant psychoactive medication use within 48 hours of initiation.

Comparative StudyMeasurement of pleural pressure swings with a fluid-filled esophageal catheter vs pulmonary artery occlusion pressure.
Pleural pressure measured with esophageal balloon catheters (Peso) can guide ventilator management and help with the interpretation of hemodynamic measurements, but these catheters are not readily available or easy to use. We tested the utility of an inexpensive, fluid-filled esophageal catheter (Peso) by comparing respiratory-induced changes in pulmonary artery occlusion (Ppao), central venous (CVP), and Peso pressures. ⋯ A fluid-filled esophageal catheter provides a high-quality, easily accessible, and inexpensive measure of change in pleural pressure and provided insights into patient-ventilator interactions.

Statistical models for fever forecasting based on advanced body temperature monitoring.
Body temperature monitoring provides health carers with key clinical information about the physiological status of patients. Temperature readings are taken periodically to detect febrile episodes and consequently implement the appropriate medical countermeasures. However, fever is often difficult to assess at early stages, or remains undetected until the next reading, probably a few hours later. ⋯ Both of them exhibited a fever peak forecasting accuracy greater than 84%. When compared with experts' assessment, both models identified 35 (97.2%) of 36 fever spikes. The models proposed are highly accurate in forecasting the appearance of fever spikes within a short period in patients with suspected or confirmed febrile-related illnesses.

Disparities in hemodynamic resuscitation of the obese critically ill septic shock patient.
With a growing obesity epidemic, the approach to care of this patient remains controversial and in many circumstances different than the general population. Appropriate hemodynamic support, although still controversial, remains a cornerstone of septic shock therapy. Catecholamines are currently recommended by guidelines without a preferred dosing strategy. However, the use of weight-based (μg kg-1 min-1) or nonweight-based (μg/min) vasopressor drip rates may impact patient care in these populations. ⋯ This study calls into question the adequacy of a nonweight-based approach to hemodynamic support of critically ill obese patients. This strategy seems to result in less aggressive, lower weight-based vasopressor and fluid doses, and more diverse approach than their nonobese counterparts.
