| 4 | “Streets of Fire”revisited:contact burns显示文摘Background:Pavement-street contact burns are rare.This study compared recent contact burns to those published in“Pavement temperature and burns:Streets of Fire”in 1995.The hypothesis was that there were a significantly increased number of pavement-street burns,as a result of increased ambient temperatures,and that motor vehicle crash(MVC)contact burns were less severe than pavements-street burns.Methods:This was a retrospective burn center registry study of naturally heated surface contact burns during May to September from 2016 to 2018.Statistical analyses were performed with one-way analysis of variance(ANOVA)and Maximum Likelihood chi-squared for age,percent of total burn surface area(%TBSA),treatment,hospitalization,comorbidities,hospital charges,mortality,ambient,and surface temperatures(pavement,asphalt,rocks).Results:In the 1995 study,median ambient temperatures were 106(range 100–113)°F compared to the 108(range 86–119)°F highest noon temperature in the current study.No ambient temperature differences were recorded on days with pavement burn admissions compared to days without these admissions.There were 225 pavement,27 MVC,15 road rash,and 103 other contact burns.The major injuries in the pavement group were due to being“down”(unknown reason),falls,and barefoot.Compared to the others,the pavement group was older,56+years,p<0.001,and had smaller burns but similar length of stay.Fifty percent of the 225 pavement group patients with full-thickness burns required skin grafts.There were 13(6%)fatalities in the pavement group vs 1(4%)in the MVC group,p=0.01.Fatalities were secondary to sepsis,shock,cardiac,respiratory,or kidney complications.Compared to survivors,the non-survivors had a significantly higher%TBSA(10%vs 4%),p=0.01,and lower Glasgow Coma Scores(10 vs 15),p=0.002.Conclusion:There was a median 2°F increase in ambient temperature since 1995.The increase in pavement burn admissions was multi-factorial:higher temperatures,population,and the number of older patients,with increased metropolis expansion,outreach,and urban heat indices.Pavement group was similar to the MVC group except for significantly older age and increased mortality.Morbidity associated with age contributed to increased mortality. | Areta Kowal-Vern Marc R.Matthews Karen N.Richey Kathy Ruiz Michael Peck Arpana Jain Kevin N.Foster | 2019 | Burns & Trauma2019，7，1： | 0 |
