Using a large national database, we evaluated the relationship between RBC transfusion volume, RBC transfusion rate, and in-hospital mortality to explore the presence of a futility threshold in trauma...
The ACS-TQIP 2013 to 2018 database was analyzed. Adult patients who received ultramassive blood transfusion (≥20 units of RBC/24 hours) were included. RBC transfusion volume and rate were captured at ...
Among 5,135 patients analyzed, in-hospital mortality rate was 62.1% (n = 3,190), and 4-hour and 24-hour mortality rates were 17.53% (n = 900) and 42.41% (n = 2,178), respectively. RBC transfusion volu...
RBC transfusion volume within 4 or 24 hours and mean RBC transfusion rate within 4 hours were not markers of futility. The observed maximum length of survival per mean RBC transfusion rate could infor...
Whole blood is gaining popularity in the treatment of traumatic massive haemorrhage. The prospective study of Hazelton et al. in 2022 shows that mortality is reduced in patients treated with whole blo...
Autoimmune rheumatic disorders (ARD) represent a wide spectrum of disorders that affect in priority the joints, bones, muscles, and connective tissues. Examples of ARD include rheumatoid arthritis, sy...
The scant evidence on the use of transfusions in neonatal care explains the limitations of current clinical guidelines. Despite this, in this document we explore the most recent evidence to make recom...
Data demonstrate the benefit of blood product administration near point-of-injury (POI). Fresh whole blood transfusion from a pre-screened donor provides a source of blood at the POI when resources ar...
We conducted a prospective, observational study of medics with varying levels of experience. Inexperienced medics were those with minimal or no reported experience learning the autologous transfusion ...
The median number of attempts for inexperienced and experienced medics was 1 versus 1 (interquartile range 1-1 for both, p = .260). The inexperienced medics had a slower median time to needle venipunc...
Inexperienced medics have longer procedure times when training autologous whole blood transfusion skills. This data will help establish training measures of performance for skills optimization when le...
Whether clinical practice guidelines have a significant impact on practice is unclear. The effect of guideline recommendations on clinical practice often a lags behind the date of publication. We eval...
RhD-negative blood products are in chronic short supply leading to renewed interest in utilizing RhD-positive blood products for emergency transfusions. This study assessed parental perceptions of eme...
A survey of parents/guardians was conducted on their tolerance of transfusing RhD-positive blood to RhD-negative female children ≤17 years old at four level 1 pediatric hospitals....
In total, 621 parents/guardians were approached of whom 378/621 (61%) completed the survey in its entirety and were included in the analysis. Respondents were mostly females [295/378 (78%)], White [24...
Most parents were willing to accept RhD-positive blood products on behalf of RhD-negative female children in an emergency situation. Further discussions and evidence-based guidelines on transfusing Rh...
Repeated red blood cell (RBC) transfusions in preterm neonates cause the progressive displacement of fetal hemoglobin (HbF) by adult hemoglobin. The ensuing increase of oxygen delivery may result at t...
Blood transfusions are essential to treating anaemia of burn injuries. It has recently been observed that patients with non-major burns < 20%TBSA may also develop anaemia requiring transfusion of bloo...
To determine risk factors for transfusion of blood products in patients with non-major burn injuries and assess transfusion practices to establish impact on patient outcome....
Our study included 182 adult patients with non-major burn injuries, < 20%TBSA admitted over a 3-year period at the Department of Plastic Surgery and Burns Unit of the Emergency County Hospital Cluj-Na...
37.9% of patients included in our study developed anaemia throughout admission and 7.7% underwent blood transfusions. Mean Hb levels triggering blood transfusions have been recorded at 7.4 (IQR=8.8-9....
Patient related comorbidities correlate with higher transfusion rates in non-major burn injuries. Due to the risk associated with the use of blood products decision to transfuse should adhere to curre...
Sc1 is a high-prevalence blood group antigen that is part of the Scianna blood group system. The clinical significance of Scianna antibodies is not well understood because of their rarity; there are o...
