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.
