<b><i>Purpose:</i></b> The aim was to examine the predictive value of the hypovolemic shock classification currently accepted by the Advanced Trauma Life Support (ATLS) program over the previous one, which used only vital signs (VS) for patient allocation. The primary outcome was 30-day mortality; as secondary outcome, heart rate (HR), systolic blood pressure (SBP), Glasgow Coma Scale (GCS) and base deficit (BD) data were compared and investigated in terms of mortality prediction. <b><i>Methods:</i></b> Retrospective analysis at a level I trauma center between 2014 and 2019. Adult patients treated by trauma teams were allocated into severity classes (I–IV) based on the criteria of the current and previous ATLS classifications, respectively. The prognostic values for the classifications were determined with Fisher’s exact test and χ<sup>2</sup> test for independence, and compared with the 2-proportion Z test. The individual variables were analyzed with receiver-operating characteristic (ROC) analyses. <b><i>Results:</i></b> A total of 156 patients met the inclusion criteria. Mortality was effectively predicted by both classifications, and there was no statistically significant difference between the predictive performances. According to ROC analyses, GCS, BD and SBP had significant prognostic values while HR change was ineffective in this regard. <b><i>Conclusions:</i></b> The currently used ATLS shock classification does not appear to be superior to the VS-based previous classification. GCS, BD and SBP are useful parameters to predict the prognosis. Changes in HR do not reflect the clinical course accurately; thus, further studies will be needed to determine the value of this parameter in trauma-associated hypovolemic-hemorrhagic shock conditions.

Abstract Background: The aim was to compare the predictive performance of the current, extended (VS+BD) Advanced Trauma Life Support (ATLS) classification for hypovolaemic shock over the previous, vital sign (VS)-based classification with respect to mortality outcomes. We also studied the prognostic values of heart rate (HR), systolic blood pressure (SBP), Glasgow Coma Scale (GCS) and base deficit (BD).Methods: The present study is a retrospective analysis at a level I trauma centre between 11 July 2014 and 11 September 2019. Trauma patients (inclusion criteria: trauma team activation, transport directly from scene, no need for resuscitation on scene, precise and detailed medical documentation, age ≥16, 30-day follow-up, complete dataset for HR, SBP, GCS and BD) were allocated to shock classes (I–IV) based on the VS and VS+BD criteria. The predictive values for the classifications were compared with a two-proportion Z-test, while individual parameters were examined with receiver operating characteristic (ROC) analyses.Results: A total of 156 patients met the inclusion criteria out of 60,037 trauma admissions. Both the VS and VS+BD classifications have shown a strong relation to mortality (P=0.0001 vs. P=0.000009). There was no significant difference in their predictive performance. According to the statistical analysis, GCS, BD and SBP showed significant prognostic values (AUCGCS=0.799 [CI: 0.722, 0.875]; AUCBD=0.683, [CI: 0.576, 0.790]; AUCSBP=0.633, [CI: 0.521, 0.744]). HR was found ineffective in predicting mortality. Conclusions: The current ATLS classification for hypovolaemic shock did not appear to be superior to the previous, VS-based classification in our study setting. GCS, BD and SBP were proven to be useful parameters in prognosticating outcome. The role of HR should be reconsidered, since it does not seem to reflect the clinical condition accurately.

The purpose of this study was to examine the impact of in-house attending surgeon supervision on the rate of preventable deaths (PD) and complications (PC) at the beginning of the academic year. All trauma patients admitted to the Los Angeles County 1 University of Southern California Medical Center over an 8-year period ending in December 2009 were reviewed. Morbidity and mortality reports were used to extract all PD/PC. Patients admitted in the first 2 months (July/ August) of the academic year were compared with those admitted at the end of the year (May/June) for two distinct time periods: 2002 to 2006 (before in-house attending surgeon supervision) and 2007 to 2009 (after 24-hour/day in-house attending surgeon supervision). During 2002 to 2006, patients admitted at the beginning of the year had significantly higher rates of PC (1.1% for July/ August vs 0.6% for May/June; adjusted odds ratio [OR], 1.9; 95% confidence interval [CI], 1.1 to 3.2; P < 0.001). There was no significant difference in mortality (6.5% for July/August vs 4.6% for May/ June; adjusted OR, 1.1; 95% CI,0.8 to 1.5; P = 0.179). During 2007 to 2009, after institution of 24-hour/day in-house attending surgeon supervision of fellows and housestaff, there was no significant difference in the rates of PC (0.7% for July/August vs 0.6% for May/June; OR, 1.1; 95% CI, 0.8 to 1.3; P = 0.870) or PD (4.6% for July/August vs 3.7% for May/June; OR, 1.3; 95% CI, 0.9 to 1.7; P = 0.250) seen at the beginning of the academic year. At an academic Level I trauma center, the institution of 24-hour/day in-house attending surgeon supervision significantly reduced the spike of preventable complications previously seen at the beginning of the academic year.

AbstractIntroductionThe aim of this study was to determine the effect of prehospital time and advanced trauma life support interventions for trauma patients transported to an Iranian Trauma Center.MethodsThis study was a retrospective study of trauma victims presenting to a trauma center in central Iran by Emergency Medical Services (EMS) and hospitalized more than 24 hours. Demographic and injury characteristics were obtained, including accident location, damaged organs, injury mechanism, injury severity score, prehospital times (response, scene, and transport), interventions and in-hospital outcome.ResultsTwo thousand patients were studied with an average age of 36.3 (SD = 20.8) years; 83.1% were male. One hundred twenty patients (6.1%) died during hospitalization. The mean response time, at scene time and transport time were 6.6 (SD = 3), 11.1 (SD = 5.2) and 12.8 (SD = 9.4), respectively. There was a significant association of longer transport time to worse outcome (P = .02). There was a trend for patients with transport times >10 minutes to die (OR: 0.8; 95% CI, 0.1-6.59). Advanced Life Support (ALS) interventions were applied for patients with severe injuries (Revised Trauma Score ⩽7) and ALS intervention was associated with more time on scene. There was a positive association of survival with ALS interventions applied in suburban areas (P = .001).ConclusionIn-hospital trauma mortality was more common for patients with severe injuries and long prehospital transport times. While more severely injured patients received ALS interventions and died, these interventions were associated with positive survival trends when conducted in suburban and out-of-city road locations with long transport times.HosseinpourM, ParavarM, MohammadzadehM, MirzadehAS.

BACKGROUND AND OBJECTIVES: Infants hospitalized with bronchiolitis are commenced on nasogastric feeding to maintain hydration. Feeding strategies vary according to physician or institution preference. The current study hypothesized that continuous nasogastric feeding would prolong length of stay (LOS) when compared to bolus feeding. METHODS: A randomized, parallel-group, superiority clinical trial was performed within an Australian children’s hospital throughout 2 bronchiolitis seasons from May 2018 to October 2019. Infants &lt;12 months hospitalized with bronchiolitis and requiring supplemental nasogastric feeding were randomly assigned to continuous or bolus nasogastric regimens. LOS was the primary outcome. Secondary outcome measures included pulmonary aspirations and admissions to intensive care. RESULTS: The intention-to-treat analysis included 189 patients: 98 in the bolus nasogastric feeding group and 91 in the continuous group. There was no significant difference in LOS (median LOS of the bolus group was 54.25 hours [interquartile range 40.25–82] and 56 hours [interquartile range 38–78.75] in the continuous group). A higher proportion of admissions to intensive care was detected in the continuous group (28.57% [26 of 91] of the continuous group vs 11.22% [11 of 98] of the bolus group [P value 0.004]). There were no clinically significant pulmonary aspirations or statistically significant differences in vital signs between the groups within 6 hours of feed initiation. CONCLUSIONS: No significant difference in LOS was found between bolus and continuous nasogastric feeding strategies for infants hospitalized with bronchiolitis. The continuous feeding group had a higher proportion of intensive care admissions, and there were no aspiration events.

ACS-verified trauma centers show higher survival and improved mortality rates in states with ACS-verified Level I pediatric trauma centers. However, few significant changes are appreciated in the first two years after verification. Minimal research exists examining verification of ACS Level II pediatric trauma centers. We analyzed ACS Level II pediatric trauma verification at our institution. In 2014, Sanford Medical Center Fargo became the only Level II pediatric trauma center in North Dakota, as well as the only center between Spokane and Minneapolis. A retrospective review of the institution's pre-existing trauma database one year pre- and postverification was performed. Patients aged <18 years were included in the study ( P < 0.05). Patient number increased by 23 per cent, from 167 to 205 patients. A statistically significant increase occured in the three to six year old age group ( P = 0.0002); motorized recreational vehicle ( P = 0.028), violent ( P = 0.009), and other ( P = 0.0374) mechanism of injury categories; ambulance ( P = 0.0124), fixed wing ( P = 0.0028), and personal-owned vehicle ( P = 0.0112) modes of transportation. Decreased public injuries ( P = 0.0071) and advanced life support ambulance transportation ( P = 0.0397). The study showed a nonstatistically significant increase in mean Injury Severity Score (from 6.3 to 7) and Native American trauma (from 14 to 20 per cent). Whereas prolonged ACS Level I pediatric trauma center verification was found to benefit patients, minimal data exist on ACS Level II verification. Our findings are consistent with current Level I ACS pediatric trauma center data. Future benefits will require continued analysis because our Level II pediatric trauma center continues to mature and affect our rural and large Native American community.

AbstractIntroduction:The administration of naloxone therapy is restricted by scope of practice to Advanced Life Support (ALS) in many Emergency Medical Services (EMS) systems throughout the United States. In Delaware’s two-tiered EMS system, Basic Life Support (BLS) often arrives on-scene prior to ALS, but BLS providers were not previously authorized to administer naloxone. Through a BLS naloxone pilot study, the researchers sought to evaluate BLS naloxone administration and timing compared to ALS.Hypothesis:After undergoing specialized training, BLS providers would be able to appropriately administer naloxone to opioid overdose patients in a more timely manner than ALS providers.Methods:This was a retrospective, observational study using data collected from February 2014 through May 2015 throughout a state BLS naloxone pilot program. A total of 14 out of 72 state BLS agencies participated in the study. Pilot BLS agencies attended a training session on the indications and administration of naloxone, and then were authorized to carry and administer naloxone. Researchers then compared vital signs and the time of BLS arrival to administration of naloxone by BLS and ALS. Data were analyzed using paired and independent sample t-tests, as well as chi-square, as appropriate.Results:A total of 131 incidents of naloxone administration were reviewed. Of those, 62 patients received naloxone by BLS (pilot group) and 69 patients received naloxone by ALS (control group). After naloxone administration, BLS patients showed improvements in heart rate (HR; P &lt; .01), respiratory rate (RR; P &lt; .01), and pulse oximetry (spO2; P &lt; .01); ALS patients also showed improvement in RR (P &lt; .01), and in spO2 (P = .005). There was no significant improvement in HR for ALS providers (P = .189).There was a significant difference in arrival time of BLS to the time of naloxone administration between the two groups, with shorter times in the BLS group compared to the ALS group (1.9 minutes versus 9.8 minutes; P &lt; .01); BLS administration was 7.8 minutes faster when compared to ALS administration (95% CI, 6.2-9.3 minutes).Conclusions:Patients improved similarly and received naloxone therapy sooner when treated by BLS agencies carrying naloxone than those who awaited ALS arrival. All EMS systems should consider allowing BLS to carry and administer naloxone for an effective and potentially faster naloxone administration when treating respiratory compromise related to opiate overdose.

Trauma centers are designated by the American College of Surgeons (ACS) into four different levels based on resources, volume, and scientific and educational commitment. The purpose of this study was to evaluate the relationship between ACS center designation and outcomes after early thoracotomy for trauma. The National Trauma Databank (v. 7.0) was used to identify all patients who required early thoracotomy. Demographics, clinical data, and outcomes were extracted. Patients were categorized according to ACS trauma center designation. Multivariate logistic regression was used to evaluate the impact of ACS trauma center designation on mortality. From 2002 to 2006, 1834 (77.4%) patients were admitted to a Level I ACS verified trauma center, 474 (20.0%) to a Level II, and 59 (3.6%) to a Level III/IV facility. After adjusting for differences between the groups, there were no significant differences in mortality (overall: 53.3% for Level I, 63.1% for Level II, and 52.5% for Level III/IV, adjusted P = 0.417; or for patients arriving in cardiac arrest: 74.9% vs 87.1% vs 85.0%, P = 0.261). Subgroup analysis did not show any significant difference in survival irrespective of mechanism of injury. Glasgow Coma Scale score # 8, Injury Severity Score >16, no admission systolic blood pressure, time from admission to thoracotomy, and nonteaching hospitals were found to be independent predictors of death. For trauma patients who have sustained injuries requiring early thoracotomy, ACS trauma center designation did not significantly impact mortality. Nonteaching institutions however, were independently associated with poorer outcomes after early thoracotomy. These findings may have important implications in educational commitment of institutions. Further prospective evaluation of these findings is warranted.

Diaphragmatic injuries (DIs) are difficult to diagnose and often go unrecognized after blunt trauma. We proposed that CT scan with coronal reconstruction (CTCR) improves the detection of small DIs missed by chest x-ray (CXR) and CT scan with axial views (CTAX). We performed a retrospective review at a Level I trauma center from 2001 to 2006 and identified 35 patients who underwent operative repair of DI after blunt trauma. The size of the DI and the radiographic test (CXR, CTAX, and CTCR) that identified the defect was compared. Results were analyzed using mean, Mann-Whitney U test, and Fisher exact test. Of the 35 DI repairs, nine were performed after CXR alone and 12 after identification by both a CXR and CTAX. There was no significant difference between the mean DI size identified by CXR with and without CTAX (10.6 vs 9.7, P = 0.88). The remaining 14 DIs were undetected by CXR and CTAX. Seven of these (before CTCR) were found during exploratory laparotomy and seven were identified by CTCR (4.6 cm vs 3.5 cm, P = 0.33). The mean DI size identified by CTCR was significantly smaller than that identified by CXR alone (4.6 cm vs 9.7 cm, P < 0.05) and by CXR and CTAX (4.6 cm vs 10.6 cm, P < 0.0005). CTCR improves the ability to detect smaller DI defects (4 to 8 cm) that were previously missed by CXR and CTAX. CTAX adds little to CXR alone for the diagnosis of large defects (greater than 8 cm).
