Abstract
in English, French

A retrospective study was conducted on 314 burn patients with inhalation injury admitted to the National Burn Hospital during the period 2015-2019. The results showed that adult and male was predominant (81.9% and 77.7%), with burns mostly caused by flame (93.6%) and burn extent of 68.6±24.3% and deep burn area of 44.6±25.2% total body surface area. Rate of required mechanical ventilation patients was 95.22%. Common complications were multiple organ failure (41.9%), pneumonia (29.9%), ARDS (25.5%) and septic shock (23.8%), with a mortality rate of 85.4%. Multivariate logistic analysis indicated that burn extent and age were independent risk factors for death of patients with inhalation injury. SMR of rBaux score was 1.01 with AUC of 0.84, Youden index 113, sensitivity 82.09%, specificity 70.21%. The SMR of adult and elderly patients was relatively close to 1 (1 and .97 respectively). In addition, the AUC value for the elderly was highest (.95) followed by adult patients (.84). However, predicting the value of rBaux on children with inhalation injury was quite low (SMR=1.57; AUC = 0.4). There is a need to determine an optimal prognosis score for children with inhalation injury.

Nous avons réalisé une étude rétrospective sur 314 patients ayant inhalé des fumées hospitalisés dans le CTB national entre 2015 et 2019. Les hommes (77,71%), les adultes (81,85%) et les brûlés par flamme (93,6%) étaient majoritaires dans ce groupe. La surface brûlée moyenne était de 68,6 +/- 24,3% dont 44,6 +/-25,2% de profond. Une ventilation mécanique a été nécessaire dans 95,22% des cas. Les complications les plus fréquentes étaient les défaillances multiviscérales (41,9%), les pneumonies (29,9%), le SDRA (25,5%) et les chocs septiques (23,8%). La mortalité était de 85,4%. En analyse multivariée, l’âge et la surface brûlée ressortaient comme des facteurs de risque indépendants de mortalité. Le Baux modifié avait un SMR de 1,01; une AUCROC de 0,84; un index de Youden à 113, une sensibilité de 82,09% et une spécificité de 70,21%. Les SMR étaient proches de 1 chez les adultes (1) et les sujets âgés (0,97). La valeur la plus élevée de l’AUC (0,95) correspondait à la cohorte «sujets âgés», suivie de la cohorte «adultes» (0,84). Le Baux modifié est peu efficace chez l’enfant (SMR 1,57 ; AUC 0,4). Il est nécessaire de développer un score pronostique pour les enfants brûlés ayant inhalé des fumées.
