Critical Emergency Department Interventions and Clinical Deterioration in Children With Nonsevere Traumatic Intracranial Hemorrhage.

OBJECTIVE: Substantial practice variation exists in the management of children with nonsevere traumatic intracranial hemorrhage (tICH). A comprehensive understanding of rates and timing of clinically important tICH, including critical interventions and deterioration, along with associated clinical and neuroradiographic characteristics, will inform accurate risk stratification. METHODS: We conducted a single-center retrospective cohort study of children aged younger than 18 years evaluated in the emergency department (ED) from May 1, 2014 to February 28, 2020 with tICH and initial Glasgow Coma Scale (GCS) score of higher than 8. We determined rates of clinically important tICH after injury and within 96 hours of ED arrival, defined as immediate ED interventions (intubation, hyperosmotic agents, or neurosurgery within 4 hours of arrival) or clinically important deterioration (signs/symptoms with change in management). Associations between outcome and clinical and neuroradiographic characteristics were calculated using individual logistic regression models. RESULTS: Our sample included 135 children. Clinically important tICH was observed in 13.3% (n = 18); 9 (6.7%) underwent immediate ED interventions and 9 (6.7%) developed deterioration. Most (93.3%, n = 127) presented with an initial GCS ≥ 14, including all children who later deteriorated. Initial GCS (P = 0.001) and nonaccidental trauma (P = 0.024) mechanism were associated with the outcome. None of the 71 (52.6%) children with initial GCS ≥ 14, isolated, nonepidural hemorrhage after accidental injury developed clinically important tICH. CONCLUSIONS: Clinically important tICH occurred in 13% of children with nonsevere tICH, and 7% of children who did not undergo immediate ED interventions later deteriorated, all of whom had an initial GCS ≥ 14. However, a subgroup of children was identified as low risk based on clinical and neuroradiographic characteristics.

Screening for Child Abuse in Children With Isolated Skull Fractures.

OBJECTIVE: Head trauma is the most common cause of death from child abuse, and each encounter for recurrent abuse is associated with greater morbidity. Isolated skull fractures (ISF) are often treated conservatively in the emergency department (ED). We determined patterns of physical abuse screening in a children's hospital ED for children with ISF. METHODS: A retrospective review was performed for children aged 3 years and younger who presented to the ED with ISF from January 1, 2015 to December 31, 2019. Children were stratified by age (<12 mo, ≥12 mo) and witnessed versus unwitnessed injury. Primary outcome was social work (SW) assessment to prescreen for abuse. Secondary outcomes were suspicion for abuse based on Child Protective Services (CPS) referral and subsequent ED encounters within 1 year. RESULTS: Sixty-six ISF patients were identified. Of unwitnessed injury patients aged younger than 12 months (n = 17/22), 88.2% (n = 15/17) underwent SW assessment and 47.1% (n = 8/17) required CPS referral. Of witnessed injury patients aged younger than 12 months (n = 23/44), 60.9% (n = 14/23) underwent SW assessment, with no CPS referrals. Overall, 18.2% (n = 4/22) unwitnessed and 20.5% (n = 9/44) witnessed injury patients returned to our ED: 2 were aged younger than 12 months and had recurrent trauma. CONCLUSIONS: To decrease risk of missed physical abuse, SW consultation should be considered for all ISF patients.

Postoperative narcotic utilization in single incision laparoscopic-assisted extracorporeal appendectomy (SILEA): a single-institution retrospective review.

PURPOSE: Laparoscopic appendectomy for pediatric acute appendicitis is commonly performed by pediatric surgeons. A single incision approach has been investigated, but the lack of technical uniformity has resulted in conflicting data. We hypothesized that an initial single incision laparoscopic-assisted extracorporeal appendectomy (SILEA) approach is associated with similar complication rates as compared to the standard three-incision laparoscopic appendectomy (TILA). METHODS: Approximately 1300 laparoscopic appendectomies were retrospectively reviewed for acute appendicitis over a 5 year period. Patients were split into TILA or SILEA cohorts. Propensity score matching identified 102 matched cases in both cohorts. Case and control cohort comparisons were then analyzed. RESULTS: Successful SILEA was associated with no difference in post-operative complication rate. SILEA was associated with decreased postoperative narcotic dosage and shorter operative time than TILA. CONCLUSIONS: An initial SILEA approach is safe and associated with similar complication rates as TILA. Based on this data, the authors advocate adoption of the an initial SILEA approach for uncomplicated, freely mobile, acute appendicitis with seamless conversion to TILA if the appendix is not amendable to SILEA. LEVEL OF EVIDENCE: Level III.

Emergence of F-waves after repetitive nerve stimulation.

AIM: Absence of the F-wave may represent the inability of spinal motor neurons to be excited after periods of inactivity. Repetitive stimulation in an otherwise immobile patient acts as a voluntary movement therefore allowing for the production of an F-wave in a patient with previously demonstrated absent F-waves. Through this case report, we attempt to highlight that the absence of the F-wave may result from inexcitability of spinal motor neurons after reduced mobilization. CASE: We present the case of a 48-year-old woman who had been hospitalized in an ICU setting for almost one month due to a subarachnoid hemorrhage, pancreatitis, and respiratory failure. An electromyogram and nerve conduction study (NCS) was performed for weakness in all four extremities. On routine NCS, her F-waves were absent, but after repetitive stimulation was performed, her F-waves appeared. DISCUSSION: This may be further evidence that the absence of the F-wave may result from inexcitability of spinal motor neurons after immobilization or reduced mobility rather than true pathology of the peripheral nerve. The ability to recover F-waves after an initial absence could assist in differentiating between inexcitability of the anterior horn cell and proximal nerve conduction block. This case presentation is an attempt to show that repetitive nerve stimulation may prove to be a useful technique to restore F-waves in patients who are unable to voluntarily contract their muscles, which may help exclude certain pathologic processes.
