Pregnancy And Burns: Guidelines For Safe Management

Background: IThe incidence of burns in pregnancy is very low, therefore little is confirmed in the specific management of pregnant women who are burned.Purpose: We conducted a study to survey the frequency of pregnancy in our patients and evaluate the risk factors of mortality for mother and foetus. Finally we provide recommendations about management of mother and child.Materials and methods: Retrospectively, we surveyed data of our pregnant patients for an 18 year period. All demographic data, gestational age, history of previous pregnancy or miscarriage, diabetes, suicide, number of operations, presence of inhalation injury, TBSA, percentage of burn in abdomen and lower extremity, early excision and outcome of mother and foetus were gathered in a special questionnaire. Uni-variate regression and multivariate regression were done for mortality of mother and child.Results: We treated 89 pregnant patients. Mean (SD) of mother's age and their pregnancy age were 24.08 +/- 5.56 years and 19.18 +/- 9.24 weeks, respectively. Mean TBSA (SD) was 36 (18%). Median of TBSA was 38 (IQR: 25, 70). Median of TBSA in Abdomen was 8 (IQR: 7, 9). Median of TBSA in lower extremities was 18 (IQR: 9, 34). Nine cases were due to attempted suicide. For 34 patients skin grafting was done. The main cause of death of the mothers was sepsis. The infections were due to Pseudomonas aeruginosa, Acinetobacter, E. coli, Klebsiella and Staphylococcus. In uni-variate regression model, TBSA, gestational week, and burns involving the abdomenwere related to maternal mortality. In multi-variate regression model, TBSA had high influence on maternal mortality, with every percent of burn surface area, the risk of mortality increased by 3.4% (p-value <0.005). In a uni-variate regression, TBSA and abdominal burn was associated with foetal mortality. However, in the multi-variate regression, only inhalation injury and TBSA had association with foetal mortality. Inhalation injury increased foetal mortality up to 16 times (p-value <0.05).Conclusion: TBSA burned is the only major risk factor of maternal mortality. TBSA burned and inhalation injury are the main risk factors of foetal mortality. (C) 2020 Elsevier Ltd and ISBI. All rights reserved.
