Outcomes in traumatic brain injury are improved when physiologic homeostasis is achieved as soon as possible after injury. Here are the American College of Surgeons’ recommendations. Note SBP over 110 and a hemoglobin over 7. A study looking at a more liberal transfusion target showed worse ARDS and no mortality benefit.

This study from Great Britain compared fatalities for pedestrians and cyclist struck by motor vehicles based on vehicle body type. They found :
“We conclude that in Great Britain, being hit by an SUV as opposed to a passenger car increases injury severity among pedestrians and cyclists, with the strongest effect in children.“

These authors looked at 5958 trauma patients arriving at their trauma center with a systolic blood pressure greater than 90. They calculated shock index (heart rate /sbp) for all of these and then looked at who received a blood transfusion within one hour of arrival. 211 patients received blood in that time frame. “Patients were stratified by SI using the following thresholds: ? 0.7, > 0.7 to 0.9, > 0.9 to 1.1, > 1.1 to 1.3, and > 1.3.”
“A main effect was observed for shock index with increased risk for required transfusion for patients with admission shock index >0.7 (P < 0.001). In comparison to shock index of ? 0.7, odds ratios were 2.5(1.7 - 3.8), 8.2(5.4 - 12.2), 24.9(15.1 - 41.1), 59.0(32.0 - 108.6) for each categorical increase in SI.”

Based on a review of 511 patients transferred to a level one trauma center for evaluation of facial fractures, this group developed the Facial Fracture Transfer Guidelines. they found that over half of the patients transferred to them did not require intervention and were discharged within 6 hours. These guidelines are meant to decrease unneeded transfers yet provide appropriate care to those with traumatic facial injuries.

Brain injury guidelines were designed to decrease transfers and neurosurgical consults for adults with head injuries.
A new retrospective study suggests that modified guidelines may be feasible in the pediatric population as well. More data is needed but this is an important step in assuring safe resource utilization in pediatric head injury patients.

In this Israeli study comparing mortality for trauma patients intubated in the emergency department vs the operating room, in hospital mortality was higher for the ED group before controlling for injury severity score and shock. After controlling for injury severity and shock, there was no difference in In hospital mortality. Coupled with previous research, if intubation can wait until after resuscitation and in the OR, that is ideal. And sometimes it just has to happen in the ED and we should be prepared for rapid resuscitation.

Another case series of 3 resuscitative hysterotomies, all performed by obstetricians, reported 33% maternal and 67% neonate survival.(1).
The mechanics of the procedure are:
- “Duration should not exceed 5 minutes!
- Incise from pubic symphysis to at least umbilicus with a large scalpel along linea nigra into peritoneal cavity. Layers: skin, subcutaneous tissue, fascia between the rectus muscles, peritoneum.
- Retract abdominal wall laterally
- Reflect bladder inferiorly and empty by aspiration
- Make a small incision (~5cm) vertically into the inferior presenting part of the uterus until amniotic fluid comes or through endometrium
- Insert 2 fingers and lift up uterus from foetus
- Extend uterine incision up to fundus with safety scissors curved away from foetus
- Deliver the foetus. May need to disengage the presenting part from the pelvis.
- Clamp the cord twice and cut between clamps
- Give the neonate to the neonatal resuscitation team” (2)

A literature search revealed very little evidence, however in 66 women and 68 neonates who underwent resuscitative hysterotomy for out of hospital cardiac arrest 4.5% of women and 45% of neonates survived to discharge. The longest down time was 29 minutes and 47 minutes for women and neonates respectively. While more evidence is needed, it appears this procedure should be performed as early as possible and may lead to some survival benefit.

The National Association of Emergency Medical Service Physicians reminds us that femur fractures rarely cause enough blood loss to cause hemodynamic instability (look for other sources), often have concomitant injuries in the pelvis or distal extremity, and can be effectively splinted either static or with traction (which has contraindications, complications, and technical hurdles).

This literature search from 1946-2023 looking at comparing selective use of CT scans vs whole body scans in geriatric trauma found no benefit of whole body CT in mortality, hospital length of stay or ED discharge. This study only included 15,000 pts over that very long time line. More robust, current work needs to be done on this important topic.

Looking at a year’s worth of data from the National Trauma Databank, the authors found incarcerated trauma patients were more likely to be stabbed, male, persons of color and have a higher adjusted mortality rate.

This study looked at exposure to gun violence and found increased use of mental health resources, depression and suicide risk even with a single exposure. Repetitive exposure increased suicide risk as well as mental health service utilization, depression and overall health service utilization. While further work is needed, screening our patients for gun violence exposure could undercover mental health needs.

This study looking at the type of facility that cared for rural injured patients reminds us that the majority of trauma care for rural patients occurs in non-trauma centers. This included some of the most severely injured and for many definitive care was received at these centers.
This may lead to lack of inclusion in trauma registries and under valuing the care being delivered by non-trauma centers. Protocols to facilitate transfers, air medical protocols and availability along with tele-health all are important in rural trauma care. Non-trauma designated centers are a critical part of the trauma network for rural residents and their value can not be ignored.

This study looked at pre-trauma mental health diagnosis (from medical records) and post-trauma mental health symptoms as assessed by survey. The majority of patients suffered blunt trauma and mean age was 67. Having pre/traumatic mental health diagnosis and particularly post-traumatic symptoms lead to worse health outcomes and financial conditions. Further work needs to be done to assess how to improve mental health symptoms post-traumatic injury.

The American Society of Anesthesia score was an independent predictor of 90-day mortality as
well as low functional status at one year in 720 patients presenting to a single center with
moderate to severe brain injury. When used in conjunction with other prognosticating tools such
as the Trauma and Injury Severity Score, it increased the prognostic value of these scales.

Controlling pain from rib fractures impacts morbidity and mortality. Over the past decade there has been a focus on decreasing opiate use and approaching this painful condition in a multimodal way. “The multimodal approach utilizes a combination of delivery methods including oral, parenteral, and regional single-shot or catheter-based techniques. Oral medications include opioids, non-steroidal anti-inflammatory drugs (NSAIDs), acetaminophen, skeletal muscle relaxants, alpha-2 agonists, mood stabilizers, and neuropathic pain medications. Parenteral medications encompass most of the oral options in addition to ketamine and lidocaine. Regional anesthesia includes epidural analgesia (EA), paravertebral blocks, intercostal blocks, and myofascial plane blocks.”
This study is a single center in Canada looking at medication used for patients admitted over 10 years with rib fractures along with demographics, injury severity and outcomes. The authors concluded:
“Although multimodal pain management strategies have improved over time, a large proportion of patients, even among those with flail chest, still do not receive multimodal pain management. Elderly patients, at highest risk of adverse outcomes, were less likely to receive multimodal pain management strategies and should be the target of performance improvement initiatives.”

Achieving faster homeostasis in trauma patients leads to lower mortality, less coagulopathy, and lower total blood volume transfusion requirements. This study looked at time to achieving homeostasis as defined by transfusion requirements as well as laboratory measurements in critically ill trauma patients who either received whole blood or component therapy transfusion as part of their resuscitation. Those receiving whole blood achieved statistically significant faster homeostasis.
