Background

Although the incidence of gastroschisis is increasing, risk factors are not clearly identified.

Methods

Using the Linked Birth Database from the California Office of Statewide Health Planning and Development from 1995 to 2012, patients with gastroschisis were identified by ICD-9 diagnosis/procedure code or birth certificate designation. Logistic regressions examined demographics, birth factors, and maternal exposures on risk of gastroschisis.

Results

The prevalence of gastroschisis was 2.7 cases per 10,000 live births. Patients with gastroschisis had no difference in fetal exposure to alcohol (p = 0.609), narcotics (p = 0.072), hallucinogenics (p = 0.239), or cocaine (p = 0.777), but had higher exposure to unspecified/other noxious substances (OR 3.27, p = 0.040; OR 2.02, p = 0.002). Gastroschisis was associated with low/very low birthweight (OR 5.08-16.21, p < 0.001) and preterm birth (OR 3.26-10.0, p < 0.001). Multivariable analysis showed lower risk in black (OR 0.44, p < 0.001), Asian/Pacific Islander (OR 0.76, p = 0.003), and Hispanic patients (OR 0.72, p < 0.001) compared to white patients. Risk was higher in rural areas (OR 1.24-1.76, p = 0.001). Compared to women age < 20, risk decreased with advancing maternal age (OR 0.49-OR 0.03, p < 0.001). Patients with gastroschisis had increased total charges ($336,270 vs. $9012, p < 0.001) and length of stay (38.1 vs. 2.9 days, p < 0.001). Mortality was 4.6%.

Conclusions

This is the largest population-based study summarizing current epidemiology of gastroschisis in California.

Background

Trauma is the leading cause of death in children, and most deaths occur within 24 hours of injury. A better understanding of the causes of death in the immediate period of hospital care is needed.

Methods

Trauma admissions younger than 18 years from 2009 to 2019 at a Level I pediatric trauma center were reviewed for deaths (n = 7,145). Patients were stratified into ages 0-6, 7-12, and 13-17 years old. The primary outcome was cause of death, with early death defined as less than 24 hours after trauma center arrival.

Results

There were 134 (2%) deaths with a median age of 7 years. The median time from arrival to death was 14.4 hours (interquartile range, 0.5-87.8 hours). Half (54%) occurred within 24 hours. However, most patients who survived initial resuscitation in the emergency department died longer than 24 hours after arrival (69%). Traumatic brain injury was the most common cause of death (66%), followed by anoxia (9.7%) and hemorrhage (8%). Deaths from hemorrhage were most often in patients sustaining gunshot wounds (73% vs. 11% of all other deaths, p < 0.0001), more likely to occur early (100% vs. 50% of all other deaths, p = 0.0009), and all died within 6 hours of arrival. Death from hemorrhage was more common in adolescents (21.4% of children aged 13-17 vs. 6.3% of children aged 0-6, and 0% of children aged 7-12 p = 0.03). The highest case fatality rates were seen in hangings (38.5%) and gunshot wounds (9.6%).

Conclusion

Half of pediatric trauma deaths occurred within 24 hours. Death from hemorrhage was rare, but all occurred within 6 hours of arrival. This is a critical time for interventions for bleeding control to prevent death from hemorrhage in children. Analysis of these deaths can focus efforts on the urgent need for development of new hemorrhage control adjuncts in children.

Background

There is wide variability of transfusion practices for children with hemorrhagic injuries across trauma centers. We are planning a multicenter, randomized clinical trial evaluating tranexamic acid in children with hemorrhage. Standardization of transfusion practices across sites is important to minimize confounding. Therefore, we sought to generate consensus-based transfusion guidelines for the trial.

Methods

We used a modified Delphi process utilizing a multi-site, multi-disciplinary panel of experts to develop our transfusion guidelines. A survey of 23 clinical categories on various aspects of transfusion practices was developed and distributed via SurveyMonkey®. Statements were graded on a 5-point Likert scale ("Strongly agree" to "This intervention may be harmful"). Statements were accepted if ≥ 80% of the panelists rated the statement as "Strongly agree" or "Agree". After each round, the responses were calculated and the results included on subsequent rounds.

Results

35 panelists from four pediatric trauma centers participated in the study, including 11 (31%) pediatric EM physicians, 8 (23%) pediatric trauma surgeons, 5 (14%) transfusionists, 5 (14%) pediatric anesthesiologists, and 6 (17%) pediatric critical care physicians (range of 8 to 10 from each clinical site). Four survey iterations were performed. In total 176 statements were rated and 39 were accepted by criteria across all 23 categories. An rational algorithm for transfusion in trauma was then developed.

Conclusions

We successfully developed transfusion guidelines for various aspects of the management of children with hemorrhagic injuries using a modified Delphi process with broad interdisciplinary participation. We anticipate implementation of these guidelines will help minimize heterogeneity of transfusion practices across clinical sites for the upcoming clinical trial evaluating tranexamic acid in children with hemorrhage.

Background

Trauma is the leading cause of death in children. Resuscitative endovascular balloon occlusion of the aorta (REBOA) provides temporary hemorrhage control, but its potential benefit has not been assessed in children. We hypothesized that there are pediatric patients who may benefit from REBOA.

Methods

Trauma patients <18 years old at a level 1 pediatric trauma center between 2009 and 2019 were queried for deaths, pre-hospital cardiac arrest, massive transfusion protocol activation, transfusion requirement, or hemorrhage control surgery. These patients defined the cohort of severely injured patients. From this cohort, patients with intraabdominal injuries for which REBOA may provide temporary hemorrhage control were identified, including solid organ injury necessitating intervention, vascular injury, or pelvic hemorrhage.

Results

There were 239 severely injured patients out of 6538 pediatric traumas. Of these, 38 had REBOA-amenable injuries (15.9%) with 34.2% mortality, accounting for 10.2% of all pediatric trauma deaths at one center. Eleven patients with REBOA-amenable injuries had TBI (28.9%). Patients with REBOA-amenable injuries represented 0.6% of all pediatric traumas.

Conclusion

Nearly 20% of severely injured pediatric patients could potentially benefit from REBOA. The overall proportion of pediatric patients with REBOA-amenable injuries is similar to adult studies.
