Efficacy of a massive transfusion protocol for hemorrhagic trauma resuscitation.

OBJECTIVES: New paradigm shifts in trauma resuscitation recommend that early reconstitution of whole blood ratios with massive transfusion protocols (MTP) may be associated with improved survival. We performed a preliminary study on the efficacy of MTP at an urban, Level 1 trauma center and its impact on resuscitation goals. METHODS: A case-control study was performed on consecutive critically-ill trauma patients over the course of 1 year. The trauma captain designated patients as either MTP activation (cases) or routine care without MTP (controls) in matched, non-randomized fashion. Primary outcomes were: time to initial transfusion; number of total units of packed red blood cells (pRBC) and fresh frozen plasma (FFP) transfused; and ratio of pRBC to fresh frozen plasma (pRBC:FFP). Secondary outcomes were in-hospital mortality, and length of stay. RESULTS: Out of 226 patients screened, we analyzed 58 patients meeting study criteria (32 MTP, 26 non-MTP). Study characteristics for the MTP and non-MTP groups were similar except age (34.0 vs. 45.85 years, p=0.015). MTP patients received blood products more expeditiously (41.7 minutes vs. 62.1 minutes, p=0.10), with more pRBC (5.19 vs 3.08 units, p=0.05), more FFP (0.19 vs 0.08 units, p<0.01), and had larger pRBC:FFP ratios (1.90 vs 0.52, p<0.01). Secondary outcomes did not differ significantly but the MTP group was associated with a trend for decreased hospital length of stay (p=0.08). CONCLUSIONS: MTP resulted in clinically significant improvements in transfusion times and volumes. Further larger and randomized studies are warranted to validate these findings to optimize MTP protocols.

Clinical decision making in seizures and status epilepticus.

Seizures and status epilepticus are frequent neurologic emergencies in the emergency department, accounting for 1% of all emergency department visits. The management of this time-sensitive and potentially life-threatening condition is challenging for both prehospital providers and emergency clinicians. The approach to seizing patients begins with differentiating seizure activity from mimics and follows with identifying potential secondary etiologies, such as alcohol-related seizures. The approach to the patient in status epilepticus and the patient with nonconvulsive status epilepticus constitutes a special clinical challenge. This review summarizes the best available evidence and recommendations regarding diagnosis and resuscitation of the seizing patient in the emergency setting.
