Assessment of Coagulation by Thromboelastography During Ongoing Postpartum Hemorrhage: A Retrospective Cohort Analysis.
Rapid assessment of hemostasis during postpartum hemorrhage (PPH) is essential to allow characterization of coagulopathy, to estimate bleeding severity, and to improve outcome. Point of care (POC) coagulation monitors could be of great interest for early diagnosis and treatment of coagulation disorders in PPH. ⋯ During PPH, when coagulation assessment is indicated, TEG provides a rapid and reliable detection of hypofibrinogenemia ≤2 g/L and/or thrombocytopenia ≤80,000/mm. No difference in performance was evidenced between the velocity-derived parameters (K-MRTGG and FF-MRTGG) and the classical parameters (K-MA and FF-MA). However, velocity-derived parameters offer the advantage of a shorter time to obtain results: FF-MRTGG parameter is available within ≤5 minutes. POC assessment of hemostasis during PPH management may help physicians to diagnose clotting disorders and to provide appropriate hemostatic support.

Observational StudyAviation-Style Computerized Surgical Safety Checklist Displayed on a Large Screen and Operated by the Anesthesia Provider Improves Checklist Performance.
Many hospitals have implemented surgical safety checklists based on the World Health Organization surgical safety checklist, which was associated with improved outcomes. However, the execution of the checklists is frequently incomplete. We reasoned that aviation-style computerized checklist displayed onto large, centrally located screen and operated by the anesthesia provider would improve the performance of surgical safety checklist. ⋯ The implementation of a computerized surgical safety checklist system resulted in an improvement in checklist performance.

Multicenter StudyAbility of an Arterial Waveform Analysis-Derived Hypotension Prediction Index to Predict Future Hypotensive Events in Surgical Patients.
Intraoperative hypotension is associated with worse perioperative outcomes for patients undergoing major noncardiac surgery. The Hypotension Prediction Index is a unitless number that is derived from an arterial pressure waveform trace, and as the number increases, the risk of hypotension occurring in the near future increases. We investigated the diagnostic ability of the Hypotension Prediction Index in predicting impending intraoperative hypotension in comparison to other commonly collected perioperative hemodynamic variables. ⋯ The Hypotension Prediction Index provides an accurate real time and continuous prediction of impending intraoperative hypotension before its occurrence and has superior predictive ability than the commonly measured perioperative hemodynamic variables.

Observational StudyPrevalence of Isoelectric Electroencephalography Events in Infants and Young Children Undergoing General Anesthesia.
In infants and young children, anesthetic dosing is based on population pharmacokinetics and patient hemodynamics not on patient-specific brain activity. Electroencephalography (EEG) provides insight into brain activity during anesthesia. The primary goal of this prospective observational pilot study was to assess the prevalence of isoelectric EEG events-a sign of deep anesthesia-in infants and young children undergoing general anesthesia using sevoflurane or propofol infusion for maintenance. ⋯ Isoelectric EEG events were common in infants and young children undergoing sevoflurane or propofol anesthesia. Although the clinical significance of these events remains uncertain, they suggest that dosing based on population pharmacokinetics and patient hemodynamics is often associated with unnecessary deep anesthesia during surgical procedures.

Multicenter StudyRetrospective Analysis of Obstetric Intensive Care Unit Admissions Reveals Differences in Etiology for Admission Based on Mode of Conception.
The use of in vitro fertilization is increasing. The incidence of adverse outcomes is greater for women who undergo in vitro fertilization, potentially leading to intensive care unit admission. This study aimed to assess the etiology and course of intensive care unit admission in women who underwent in vitro fertilization compared to those who did not, with specific focus on intensive care unit admission due to postpartum hemorrhage. ⋯ Among patients admitted to the intensive care unit, patients with different modes of conception had dissimilar etiologies for intensive care unit admission with intensive care unit admission due to hemorrhage greater in those with in vitro fertilization. Higher rates of multiple gestation pregnancies may explain this difference. Differences in pregnancies conceived via in vitro fertilization versus without in vitro fertilization may affect the obstetric intensive care unit case mix.
