Antithrombin III in burned children

We studied haemostatic parameter and Antithrombin III (ATIII) level in 50 consecutive admissions for severe burns between 1990 to1994 to the Centro Grandi Ustionati Ospedale S. Eugenio, Rome. The criteria for inclusion in the study were age <16 years and the presence of major burns (extent of the burns >30 and second and third degree burns). Treatment consisted of initial fluid resuscitation and early excision and grafting of burn wounds and critical care support by a multidisciplinary team. Burn-related variables haemostatic values and the conditions of microcirculation were proposed and analysed with the help of Fisher exact test, χ2 test, logistic regression and discriminant analysis.
By the discriminant analysis, the coefficients of the standardized functions and the percentage of correctly classified individuals were calculated. The analysis showed total burned surface turned out to be the best predictor of survival. High discrimination efficiency was observed for age, weight, burn type (flame, scald contact chemical electrical).
By the logistic regression, the total burned surface confirmed to be the best predictor of survival and between the haemostatic variables ATIII give a significant value (p=0.0244).
Moreover, it is noteworthy that ATIII level at the onset of the disease gives a significant correlation with mortality (p=0.0005). The Fisher test showed a significant association between ATIII level and death (p=0.0005). This was confirmed by the χ2 test (p=0.00027). Considering the AT deficiency in patients with thermal injuries, we conducted a pilot study to assess AT concentrate infusions for safety and efficacy in thermal injury. The patients received AT concentrate infusions every 8 hours to raise the plasma level to 100 % in the first 72 hours after injury and were compared with control patients with burns. Day4 levels were 105%±20% in patients treated with AT patients versus 50%±14% in the control patients (P < 0.001). In the group treated with AT the time to microcirculation recovery was shorter (P < 0.02).
