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.

Typically Coccidioidomycosis is seen in the Southwestern US. The authors of this study, using climate modeling predict endemic areas will spread across the US to include Idaho, the Dakotas, Nebraska and Wyoming.
Clinically, “Patients with pulmonary Coccidioides infection frequently experience fever, cough, and shortness of breath. Chest radiographic imaging may demonstrate lobar, segmental, or multifocal consolidations; cavitary lesions; and lung nodules. Given these nonspecific findings, patients with coccidioidomycosis are often treated for community-acquired pneumonia. Coccidioidomycosis should be considered in patients not improving with antibiotic treatment or in those who have exposure to or reside in endemic areas. Up to 50% of patients with pulmonary coccidioidomycosis have erythema nodosum, approximately 25% to 30% have peripheral eosinophilia, and approximately 25% have arthralgias (particularly symmetric knee and ankle arthralgia). Up to 10% of patients diagnosed with coccidioidomycosis develop disseminated disease, including skin, central nervous system, and bone and joint infection.”

How likely is your TIA pt to go on to have a stroke? This study in JAMA gives us some answers. While EM providers aren’t as interested in 5 and 10 year prediction, it provides more evidence TIAs need to be evaluated and are risk factors for future events.
“In this systematic review and meta-analysis of 171?068 patients with TIA or minor stroke from 38 studies, the risk of subsequent stroke was 5.9% within 1 year, 12.8% within 5 years, and 19.8% within 10 years.”

This large retrospective database study compared those receiving antibiotics after anterior nasal packing to those that did not. There was no difference in clinically significant infection between the groups leading the authors to conclude prophylactic antibiotics after anterior nasal packing is not required.

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 article reminds us that hip fractures have a one year mortality rate of 12-25% and 50% of hip fracture patients develop complications while in the hospital. “Almost half of individuals hospitalized with hip fractures experience complications, such as delirium, pneumonia, acute kidney injury, urinary tract infection, and deep vein thrombosis”
Because of these complications, multidisciplinary teams should be caring for these patients and great care should be exercised when evaluating these patients.

Aortic dissection remains a difficult diagnosis to make. This article is a nice review. The pathology behind this involves an intimal flap in the aortic wall. Death occurs due to aortic rupture or obstruction of branching artery.
Risk factors: male 2:1 female, Marfan Syndrome, HTN, aortic aneurysm, cocaine and methamphetamine use, pregnancy
Pain is variable however tearing, ripping migrating, maximum at onset, and sharp are all associated with Aortic Dissection. Think about Dissection with atypical CP with ECG changes as well as in stroke like presentations along with chest pain.
Gold standard for diagnosis is CT angiogram. Decision rules with the use of D-Dimer have been proposed however there is still not sufficient evidence to use these. ACEP guidelines currently give use of decision rules a long with DDImer a level C recommendation.

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.

In the April edition of Annals of EM, there are opposing view points on the optimal antibiotic regiment for necrotizing soft tissue infection. One group proposes linezolid alone will cover all the worrisome pathogens namely group A Strep and Staph. There are less side effects including C. Diff infection with this medication. Another group suggests sticking to vancomycin plus/minus BLactam along with clindamycin. Their arguement centers around clindamycin is useful as an antitoxin more so than its antibacterial property.
Both offer reasonable evidence and neither is compelling enough to say one is superior to the other.

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.

Missed appendicitis leading to rupture and peritonitis leads to morbidity, mortality, and malpractice claims. Part of a longer article looking at evaluation and management of appendicitis, these authors provide three scoring systems that can be used to identify appendicitis. Use of these scores can guide imaging and surgical consultation.
Alvarado Score: If a patient scores 1 to 4, the risk of appendicitis drops to 33%. If a patient scores >5, the risk of acute appendicitis is 66% or greater.

This study from Australia reminds us that what patients think they ingested isn’t always what they did ingest. A high percentage of “cocaine” and other stimulants was actually fentanyl or other opiates. The authors do a nice job referencing similar studies in the United States. Any overdose could be a mixed picture due to impure street drugs.

The Jarisch-Herxheimer reaction (JHR) is a non-specific set of symptoms (fever, malaise, worsened rash, hemodynamic instability, leukocytosis) seen after treating syphillis and other spirochete induced infections. In this study 1 in 4 patients treated with 2.4 million units of benzathine penicillin G developed a short lived JHR. Those who developed the reaction were more likely HIV negative, had secondary syphillis and had successful treatment at 6 months.

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.”
