Cambios de la presión intraabdominal en pacientes grandes quemados / Changes of the intra-abdominal pressure in severely burned patients

RESUMEN Introducción: Los cambios de la presión intraabdominal en pacientes grandes quemados influyen en su evolución y se asocia con un mal pronóstico. Objetivo: Determinar los cambios de la presión intraabdominal en pacientes grandes quemados. Métodos: Se realizó un estudio observacional, descriptivo de corte transversal para determinar los cambios de la presión intraabdominal en pacientes grandes quemados, ingresados en el servicio de Cirugía Plástica y Caumatología del Hospital Universitario Manuel Ascunce Domenech de la provincia Camagüey desde enero de 2019 hasta junio de 2021.Se estudiaron 35 pacientes, se utilizaron las variables: presión intraabdominal como variable dependiente y el índice de gravedad, la presencia de quemaduras abdominales, los volúmenes de líquidos administrado y el estado al egreso de los pacientes como variables independientes. Resultados: En los tres grupos con índice pronóstico de muy grave, crítico y crítico extremo la mayoría de los pacientes presentaron niveles de presión intraabdominal grado I. De aquellos pacientes que presentaban más de un cinco por ciento de quemaduras hipodérmicas en el abdomen, 19 presentaron presión intraabdominal grado I. De los 22 pacientes que necesitaron para su reanimación diez o más litros de cristaloides, el 60 % desarrolló algún grado de hipertensión intraabdominal.Del total de la muestra, 18 de los enfermos resultaron fallecidos. Conclusiones: El índice pronóstico, la presencia de quemaduras hipodérmicas en el abdomeny la reanimación con diez o más litro de líquido, influye en los cambios de la presión intraabdominal en estos enfermos. La hipertensión intraabdominal repercute en la mortalidad en los grandes quemados.

ABSTRACT Introduction: The changes of the intra-abdominal pressure in severely burned patients influence their evolution and it has been associated with a bad forecast. Objective: To determine the changes of the intra-abdominal pressure in severely burned patients. Methods: An observational, descriptive cross-section study was carried out to determine the changes of the intra-abdominal pressure in severely burned patients, entered in the service of Plastic Surgery and Caumatology of the University Hospital Manuel Ascunce Domenech of Camagüey province in the period understood from January, 2019 to June, 2021. 35 patients were studied and the following variables were used: intra-abdominal pressure as dependent variable and severity rate, the presence of abdominal burns, the volumes of liquids administered and the state to the expenditure of the patients as independent variables. Results: In the three groups with forecast index of very bad, critic and extreme critic most of the patients presented levels of intra-abdominal pressure degree I. Of those patients that introduced more of one and five percent of hypodermic burns in the abdomen, 19 presented intra-abdominal pressure. Of the 22 patients that needed for their revival ten or more liters of crystalloids, the 60 % developed some degree of intra-abdominal hypertension. Of the total of the sample, 18 of the patients deceased. Conclusions: The forecast index, the presence of hypodermic burns in the abdomen and the revival with ten or more liter of liquid, influence the changes of the intra-abdominal pressure in these patients. The intraabdominal hypertension has influence upon the mortality in the severely burned patients.

Complications using tissue expanders in burn sequelae treatment at a reference university hospital: a retrospective study / Complicações com o uso de expansores teciduais para tratamento de sequela de queimaduras em um hospital universitário de referência: estudo retrospectivo

ABSTRACT Background: tissue expanders have high relevance in plastic surgery and among indications it is worth mentioning their use in the treatment of burn reconstruction. Although it shows good results, its use requires special care because some complications can interrupt the reconstruction process. The objective of this study was to report the experience of the Clinics Hospital (University of Sao Paulo) with the use of tissue expanders to treat burn sequelae, establishing the incidence of complications, and identifying risk factors for their occurrence. Methods: a retrospective, observational, and analytical study, evaluating the use of expanders in burns sequelae treatment from 2009 to 2018. Results: 245 expanders were placed in 84 patients, 215 were female, with a mean age of 19.96 years, being 40% in the trunk and 20% in the scalp, with a predominance of rectangular shape in 76.7% of cases. Complications were classified as major and minor.Complications occurred in 17.95% of cases, and extrusion and infection were the most common. There was a higher incidence of complications in expanders used in the upper and lower limbs as well as in those who did not undergo concomitant expansion (p <0.05), with an even higher chance of major complications in patients submitted to additional expansion. From 2009 to 2018, we observed a decrease in the incidence of complications. Conclusion: the complication rate (17.95%) is similar to other studies of the literature, there was a higher rate of complication with expanders placed in the limbs and a higher rate of major complications when additional expansion was done.

RESUMO Introdução: os expansores teciduais são de importante relevância na cirurgia plástica, e dentre suas indicações destaca-se seu uso no tratamento de sequelas de queimaduras. Ainda que apresente bons resultados, seu uso requer cuidados especiais pois a incidência de complicações não é desprezível. Objetivo: relatar a experiência do Hospital das Clínicas da FMUSP com a utilização de expansores teciduais para tratamento de sequelas de queimaduras, estabelecendo a incidência de complicações e identificando possíveis fatores de risco para ocorrência das mesmas. Método: estudo retrospectivo, observacional e analítico, avaliando o uso de expansores no tratamento de sequelas de queimaduras no período de 2009 a 2018 no Hospital das Clínicas da FMUSP. Resultados: no período de análise estabelecido, foram colocados 245 expansores, sendo 215 em pacientes do sexo feminino, com idade média de 19,96 anos, sendo 40% em tronco e 20% em couro cabeludo, predominando uso do retangular em 76,7% dos casos. As complicações foram divididas em maiores e menores. As complicações ocorreram em 17,95% dos casos, sendo extrusão e infecção as de maior incidência. Houve maior incidência de complicação em expansores utilizados nos membros superiores e inferiores bem como naqueles que não realizaram expansão concomitante (p<0,05), havendo ainda maior chance de complicações absolutas nos pacientes submetidos à expansão adicional. Observou-se também diminuição no número de complicações entre 2009 e 2018. Conclusão: a taxa de complicação (17,95%) é semelhante a da literatura, observando-se maior taxa de complicação nos expansores colocados em membros e maior taxa de complicações absolutas quando realizada expansão adicional.

Objetivo: determinar mediante el estudio bacteriológico cuantitativo de la herida por quemadura el diagnóstico de infección en pacientes quemados. Métodos: se realizó un estudio descriptivo, de corte transversal para determinar mediante el estudio bacteriológico cuantitativo de la herida por quemadura el diagnóstico de infección en los pacientes quemados ingresados en el servicio de Caumatología del Hospital Universitario Manuel Ascunce Domenech de la provincia Camagüey, desde septiembre de 2015 a noviembre de 2017. Se estudiaron 34 pacientes y se evaluaron las variables: edad, sexo, índice de gravedad, positividad o no de los estudios cualitativos y cuantitativos en relación con las manifestaciones clínicas de infección. Resultados: el sexo femenino fue el más representado con 70,59 % de casos, predominaron las edades entre 48-67 años, el 38,23 % de los lesionados estaban clasificados como muy grave, la colonización fue la predominante sobre la infección en el cultivo cuantitativo con un 26,47 %. En los pacientes con manifestaciones clínicas de infección, el cultivo bacteriológico cuantitativo fue positivo en 11 de ellos para un 32,35 %. Se encontró en el 44,12 % la presencia de gérmenes a una concentración de más de 105 gérmenes por gramo de tejido. Conclusiones: los factores determinantes en la aparición de infección en la herida por quemadura son la edad, la extensión y profundidad de las lesiones. Existió una correlación entre la positividad del estudio bacteriológico cuantitativo y la presencia de manifestaciones clínicas de infección en los pacientes. Se documentó mayor número de cultivos cuantitativos con resultados positivos y su correlación con la presencia de gérmenes en los cultivos cualitativos.

ABSTRACT Background: the infectious processes are one of the main causes of morbidity and mortality in the burned patients, which is why the early diagnosis of the infection through the bacteriological quantitative study represents a forward-motion step for the opportune treatment of these patients. Objective: to determine the diagnosis of infection in the burned patients by means of the bacteriological quantitative study of the injury by burn. Methods: a descriptive, cross-section study was carried out to determine by means of the bacteriological quantitative study of the injury by burn the diagnosis of infection in the burned patients entered in the service of Burn at Manuel Ascunce Domenech Universitary Hospital of the province Camagüey, from September 2015 to November 2017. 34 patients were studied in those who were evaluated the following variables: age, sex, severity rate, positivity or no of the qualitative and quantitative study relating to the clinical public demonstrations of infection. Results: in this study the feminine sex became represented by 70.59 %, predominating ages between 48- 67 years, the 38.23 % of injured persons were classified as very grave, and colonization was the predominant on the infection in the quantitative cultivation with a 26.47 %. In patients with clinical demonstrations of infection, the quantitative culture was positive in 11 of them for a 32.35 %. It was found in 44.12 % of patients, the presence from germs to a concentration of over 105 germen per gram of fabric. Conclusions: determining factors in the appearing of infection in the injury by burn were age, extension and depth of the injuries. There was a correlation between the positivity of the bacteriological quantitative study and the presence of clinical demonstrations of infection in these patients. Greater number of quantitative cultivations with positive results and their correlation with the presence of germs in the qualitative cultivations were documented.
