Reverse shock index multiplied by the motor component of the Glasgow Coma Scale predicts mortality and need for intervention in pediatric trauma patients

BACKGROUND

Timely identification of high-risk pediatric trauma patients and appropriate resource mobilization may lead to improved outcomes. We hypothesized that reverse shock index times the motor component of the Glasgow Coma Scale (rSIM) would perform equivalently to reverse shock index times the total Glasgow Coma Scale (rSIG) in the prediction of mortality and the need for intervention following pediatric trauma.

METHODS

The 2017-2020 National Trauma Data Bank datasets were used. We included all patients <16 years of age that had a documented prehospital and trauma bay systolic blood pressure, heart rate, and total GCS. We excluded all patients who arrived at the trauma center without vital signs and interfacility transport patients. Receiver operating characteristic (ROC) curves were used to model the performance of each metric as a classifier with respect to our primary and secondary outcomes, and the area under the ROC curve (AUC) was used for comparison. Our primary outcome was mortality prior to hospital discharge. Secondary outcomes included blood product administration or hemorrhage control intervention (surgery or angiography) < 4 hours following hospital arrival and ICU admission.

RESULTS

After application of exclusion criteria, 77,996 patients were included in our analysis. rSIM and rSIG performed equivalently as predictors of mortality in the 1-2 (p = 0.05) and 3-5 (p = 0.28) year categories, but rSIM was statistically outperformed by rSIG in the 6-12 (AUC: 0.96 vs. 0.95, p = 0.04) and 13-16 (AUC: 0.96 vs. 0.95, p < 0.01) year-old age categories. rSIM and rSIG also performed similarly with respect to prediction of secondary outcomes.

CONCLUSION

rSIG and rSIM are both outstanding predictors of mortality following pediatric trauma. Statistically significant differences in favor of rSIG were noted in some age groups. Because of the simplicity of calculation, rSIM may be a useful tool for pediatric trauma triage.

Long-term results of Rehbein's procedure: a retrospective study in German-speaking countries

AIM

In contrast to other countries, no collective study of Rehbein's procedure in German-speaking nations has been performed. Therefore, our intention was, analogously to Goto and Ikeda's (10) Japanese study in 1984, Kleinhaus's (13) study on Swenson's procedure in 1979, Bourdelat's (2) French-Canadian investigation into Duhamel's technique in 1997 and Martuciello's (11) and Teitelbaum's (16) follow-up in the year 2000, to perform a follow-up study of Rehbein's technique of deep anterior resection.

METHODS

The data of 200 patients from 22 German-speaking centers in Switzerland, Austria and Germany were collected. These data were gathered by questionnaire and the children were followed up in the individual participating hospitals for at least 3.5 years after the procedure. The procedure was performed between 1993 and 1997, over a 5-year period. The questionnaire contained 74 items including anamnestic data, diagnostic postoperative treatment and reoperations.

RESULTS

Concerning the incidence of anastomotic leaks and resolving anastomotic strictures there was no significant difference between the results in our series and those of the collective analyses made by Hofmann von Kap-herr (7), Holschneider (9) and Sherman (18). In 6.6 % of the 191 patients an anastomotic leak and in 9.9 % a rectal stricture, which had to be dilated, was observed. Concerning late complications, 22.8 % of the children suffered from constipation, 4.3 % from encopresis, 10.6 % from enterocolitis and only 0.5 % from enuresis. The frequency of constipation diminishes over the years. A comparison of the different large series in the literature clearly shows that the incidence of constipation is higher after Rehbein's procedure and the frequency of urinary incontinence and encopresis higher following Swenson's, Soave's and Duhamel's techniques. The incidence of enterocolitis is less after Rehbein's procedure than after Swenson's, Soave's and Duhamel's techniques.

CONCLUSIONS

The different results in the literature are due to the individual experience of the author, the very different follow-up methods and the date of follow-up. Therefore, the different results are hard to compare with our study. Nevertheless, Rehbein's anterior resection still could be presented as an adequate and important method to treat Hirschsprung's disease.
