Comparative StudyUse of Earlier-Reported Rotational Thromboelastometry Parameters to Evaluate Clotting Status, Fibrinogen, and Platelet Activities in Postpartum Hemorrhage Compared to Surgery and Intensive Care Patients.
Rotational thromboelastometry (ROTEM) can provide clinical information in 10-20 minutes for guiding administration of fibrinogen, platelets, and fresh frozen plasma products. While ROTEM testing is well established for cardiac and other surgeries, it is less characterized for use in postpartum hemorrhage (PPH) patients. We wanted to determine if the earlier-measured ROTEM parameters (α-angle and amplitude at 10 minutes [A10]) could replace the later parameters (amplitude at 20 minutes and maximum amplitude [maximum clot firmness {MCF}]) in all patient groups studied. We also correlated the A10 and α-angle of the EXTEM and FIBTEM tests to the fibrinogen levels and platelet counts in these patients. ⋯ The correlations among the ROTEM parameters for the PPH comparisons were equivalent to the C/T OR patients studied, and the A10EX and A10FIB could replace the MCF results in all patient groups. Also, the α-EX was an early indicator of the A10EX and had good correlations to the A10FIB and the fibrinogen in all patient groups. Finally, in a separate group of 62 comparisons, the FIBTEM α angle showed promise as an early indicator of the A10FIB and the fibrinogen levels.

Extracorporeal Membrane Oxygenation Appropriateness: An Interdisciplinary Consensus-Based Approach.
We describe a quality improvement initiative aimed at achieving interdisciplinary consensus about the appropriate delivery of extracorporeal membrane oxygenation (ECMO). Interdisciplinary rounds were implemented for all patients on ECMO and addressed whether care was consistent with a patient's minimally acceptable outcome, maximally acceptable burden, and relative likelihood of achieving either. The rounding process was associated with decreased days on venoarterial ECMO, from a median of 6 days in 2014 (first quartile [Q1]-third quartile [Q3], 3-10) to 5 days in 2015 (Q1-Q3, 2.5-8) and in 2016 (Q1-Q3, 1-8). Our statistical methods do not allow us to conclude that this change was due to our intervention, and it is possible that the observed decreases would have occurred whether or not the rounding process was implemented.
