A strain gauge transducer accom... This study explored ICP accuracy in the presence of blood and other viscous fluid contaminates in the transducer.... Preclinical comparative design study.... Laboratory setting using two Natus EVDs, two strain gauge transducers, and a sealed pressure chamber.... No human subjects or animal models were used.... A control transducer primed with saline was compared with an investigational transducer primed with blood or with saline/glycerol mixtures in mass:mass ratios of 25%, 50%, 75%, and 100% glycerol. Volu... From 90 paired observations, ICP readings were statistically significantly different between the control (saline) and experimental (glycerol or blood) transducers.

Whole blood for old blood: Use of whole blood for resuscitation in older trauma patients.

31 Jul 2024

DOI: 10.1016/j.injury.2024.111758 PMID: 39098571

Older patients are expected to comprise 40 % of trauma admissions in the next 30 years. The use of whole blood (WB) has shown promise in improving mortality while lowering the utilization of blood pro... Older trauma patients, defined as age ≥55 years old, were reviewed from March 2016-November 2021. Patients that received a WB first resuscitation strategy were compared to those that received a ratio ... There were 388 older trauma patients that received any blood products during the study period. A majority of patients received a WB first resuscitation strategy (83 %). Compared to patients that recei... The use of WB in the older trauma patient appears safe, with mortality and complication rates comparable to component therapy.
