ABSTRACT

INTRODUCTION: In the prehospital setting, crystalloid fluids are frequently used, but only erythrocytes are capable of transporting oxygen to tissues. The aim of this study was to establish the efficacy and safety of the prehospital use of uncross matched type O rhesus-negative packed red blood cells (URBC) by the Dutch physician-staffed helicopter emergency medical service. We hypothesized that prehospital URBC transfusions are safe and more effective with respect to survival than resuscitations with crystalloids. METHODS: The effects of prehospital URBC transfusions were studied by comparing a cohort of patients (>18 years) who were treated with a combination of URBC and crystalloid fluids with a matched control group of patients who received crystalloid fluids alone. RESULTS: Among 73 adults who received prehospital URBC transfusions, 50 (68%) patients were included. No transfusion reactions were observed. No effect of prehospital transfusion on 24-h or 30-day survival was found. Haemoglobin levels at presentation to the emergency department were higher in the URBC cohort. The two groups had similar cumulative erythrocyte requirements within the first 24 h. CONCLUSION: Neither survival benefits nor a decreased incidence of shock on admission were observed after prehospital helicopter emergency medical service URBC transfusions. There were no prehospital transfusion reactions in this study; therefore, URBC transfusions were deemed to be safe. A prospective randomized study is warranted to evaluate the effect of early URBC transfusions and transfusions with preheated URBC on the survival of patients with severe prehospital haemorrhagic shock.

ABSTRACT

OBJECTIVE: In the prehospital setting, the Nijmegen and Rotterdam helicopter emergency medical services administer packed red blood cells to critically ill or injured pediatric patients. Blood is given on scene or during transport and is derived from nearby hospitals. We summarize our experience with prehospital blood use in pediatric patients. METHODS: The databases from both the Nijmegen and Rotterdam helicopter emergency medical services were reviewed for all pediatric (< 18 years) patients who received packed red blood cells on scene or during transport to the hospital. RESULTS: Between 2007 and 2015, 10 pediatric patients out of approximately 2,400 pediatric patients received blood in the prehospital setting. The median Injury Severity Score was 41. Seven hospitals delivered blood in the prehospital setting at the scene. All patients were in hypovolemic shock. Two patients died. Two patients were believed to be unexpected survivors; 1 was predicted by the Trauma and Injury Severity Score, and a second unexpected survivor was a neonate who was in hypovolemic shock and cardiopulmonary arrest. CONCLUSION: The incidence of prehospital use of blood in injured or critically ill children is low. This intervention presented a potential to limit acid-base disturbance, low hemoglobin levels, and coagulopathy in this group. We believe this cohort also contains 2 unexpected survivors.

ABSTRACT

BACKGROUND: Medical students have been deployed in victim care of several disasters throughout history. They are corner stones in first-line care in recent pandemic planning. Furthermore, every physician and senior medical student is expected to assist in case of disaster situations, but are they educated to do so? Being one of Europe's densest populated countries with multiple nuclear installations, a large petrochemical industry and also at risk for terrorist attacks, The Netherlands bear some risks for incidents. We evaluated the knowledge on Disaster Medicine in the Dutch medical curriculum. Our hypothesis is that Dutch senior medical students are not prepared at all. METHODS: Senior Dutch medical students were invited through their faculty to complete an online survey on Disaster Medicine, training and knowledge. This reported knowledge was tested by a mixed set of 10 theoretical and practical questions. RESULTS: With a mean age of 25.5 years and 60 % females, 999 participants completed the survey. Of the participants, 51 % considered that Disaster Medicine should absolutely be taught in the regular medical curriculum and only 2 % felt it as useless; 13 % stated to have some knowledge on disaster medicine. Self-estimated capability to deal with various disaster situations varied from 1.47/10 in nuclear incidents to 3.92/10 in influenza pandemics. Self-estimated knowledge on these incidents is in the same line (1.71/10 for nuclear incidents and 4.27/10 in pandemics). Despite this limited knowledge and confidence, there is a high willingness to respond (ranging from 4.31/10 in Ebola outbreak over 5.21/10 in nuclear incidents to 7.54/10 in pandemics). The case/theoretical mix gave a mean score of 3.71/10 and raised some food for thought. Although a positive attitude, 48 % will place contaminated walking wounded in a waiting room and 53 % would use iodine tablets as first step in nuclear decontamination. Of the participants, 52 % even believes that these tablets protect against external radiation, 41 % thinks that these tablets limit radiation effects more than shielding and 57 % believes that decontamination of chemical victims consists of a specific antidote spray in military cabins. CONCLUSIONS: Despite a high willingness to respond, our students are not educated for disaster situations.
