Background: Early and accurate identification of pediatric trauma patients who will require massive transfusion (MT) is not well established. In adults, an ABC score >2 (defined by penetrating mechanism, positive FAST, SBP120) identifies trauma patients who require MT with sensitivity and specificity of 75 and 86%, respectively. We developed the BIS and ABCD scores and hypothesize they can improve the discriminate ability for predicting massive transfusion in children. Methods: Pediatric trauma patients who received …

Purpose: Early and accurate identification of pediatric trauma patients who will require massive transfusion (MT) remains difficult, and MT activation criteria are not well established. In children, the addition of shock index-pediatric age-adjusted (SIPA) to the ABC score (ABC-S) only modestly improves the sensitivity of the ABC score. We hypothesized that the discriminate ability of the ABC-S score would improve with the addition of elevated serum lactate and base deficit (ABCD score). Methods: We identified children between 1 and 18 years old who received a pRBC transfusion between 2008 and 2018 from our trauma registry. We calculated sensitivity, specificity, and accuracy of the ABC, ABC-S, and ABCD scores to determine the need for MT. Results: We included 211 children, of which 66 required MT. The best predictor of MT was achieved by adding BD and lactate to the ABC-S score, with an AUC of 0.805. An ABCD score of 3 or greater was 77.4% sensitive and 78.8% specific at predicting the need for MT. Pediatric trauma patients that required MT had higher injury severity score (p = 0.005), lactate (p = 0.002), base deficit (p = <0.0001). Mortality was higher in the MT group (45.5% vs 15.3%, p = 0.0004). Conclusions: The ABCD score improves the sensitivity of activating MT in pediatric trauma patients. Study Type: Treatment Study.

OBJECTIVE:Laparoscopic Nissen fundoplication is performed in neonates and children for significant gastroesophageal reflux. An aberrant left hepatic artery encountered during laparoscopic Nissen fundoplication makes dissection around the esophageal hiatus more difficult if the artery is not transected. Although some suggest division of the aberrant left hepatic artery, this is associated with risk of significant hepatic injury from ischemia. We routinely preserve the aberrant left hepatic artery and sought to determine (1) the incidence of aberrant left hepatic artery and (2) the results following preservation of the aberrant left hepatic artery.METHODS:Between January 2000 and October 2002, 195 laparoscopic Nissen fundoplications were performed. We documented intraoperative findings of each procedure, and reviewed postoperative radiographic studies and clinic visits.RESULTS:In 30 patients (15%), an aberrant left hepatic artery was identified. All dissections were performed laparoscopically with the Nissen fundoplication positioned cephalad to the aberrant left hepatic artery. Postoperatively, 2 patients (6%) have had evidence of wrap failure. The remainder of the patients has had normal radiographic studies or no clinical evidence of reflux during clinic visits.CONCLUSION:During laparoscopic Nissen fundoplication in neonates and children, an aberrant left hepatic artery may be encountered in approximately 15% of patients. When an aberrant left hepatic artery is identified, it should be preserved to avoid the potential risk of hepatic ischemic injury.
