ABSTRACT

Introduction: alterations of the internal environment leading to high morbidity and mortality in patients who suffer intestinal obstruction are considered serious complication if they are not adequately evaluated and corrected.
Objective: to characterize the behavior of the main alterations in the internal environment related to the acid-base balance in patients operated on for intestinal mechanical obstruction.
Methods: observational and descriptive case series study in patients operated on for intestinal obstruction from January 1st 2009 to December 31st 2012 in "Saturnino Lora Torres" hospital. The universe of study was made up of 257 patients, being the final sample 207 individuals. The chi-square statistic tests of independence were calculated to identify statistically significant association among the selected variables.
Results: males as well as over 61 years-old patients prevailed. The intestinal adhesions were the most common cause of obstruction. The tumor etiology was the most significant outcome associated with most of the acid-base alterations. The length of progression of symptoms was directly proportional to the occurrence of identified disorders. The mortality of the series mainly occurred in patients with cancer occlusion due to high incidence of hemogasometric alterations present in deceased patients.
Conclusions: the presence of acid-base alterations makes the course and prognosis of patients with mechanical intestinal obstruction gloomy.
