Abstract
To investigate if tests used in the preoperative period of upper abdominal or thoracic surgeries are able to differentiate the patients that presented cardiopulmonary postoperative complications. Seventy eight patients, 30 submitted to upper abdominal surgery and 48 to thoracic surgery were evaluated. Spirometry, respirometry, manovacuometry, six-minute walk test and stair-climbing test were performed. Complications from immediate postoperative to discharge from hospital were registered. The postoperative complications rate was 17% in upper abdominal surgery and 10% in thoracic surgery. In the univariate regression, the only variable that kept the correlation with postoperative complications in the upper abdominal surgery was maximal expiratory pressure. In thoracic surgery, the maximal voluntary ventilation, six-minute walk test and time in stair-climbing test presented correlation with postoperative complications. After multiple regression only stair-climbing test continued as an important risk predictor in thoracic surgery. The respiratory pressure could differentiate patients with complications in upper abdominal surgery, whereas in thoracic surgery, only spirometric values and exercise tests could differentiate them.
Highlights
MethodsThe upper abdominal and thoracic surgeries are routinely performed for treatment of many diseases, and sometimes for diagnosis
Such surgeries can present cardiopulmonary postoperative complications (POC) more frequently than the lower abdominal surgeries, as due to the surgical incision interfering in the respiratory muscles as by the own changes caused by the surgery and anesthesia
From the patients selected in UAS Group, there was a loss of five patients
Summary
The upper abdominal and thoracic surgeries are routinely performed for treatment of many diseases, and sometimes for diagnosis Such surgeries can present cardiopulmonary postoperative complications (POC) more frequently than the lower abdominal surgeries, as due to the surgical incision interfering in the respiratory muscles as by the own changes caused by the surgery and anesthesia. It is possible to intensify the pre-operative care in order to minimize the POC Tests such isolated evaluation of lung volumes and capacity, respiratory muscle strength, as well as exercise tests to determine the cardiopulmonary capacity can be performed during preoperative period. The purpose of study was determining if tests performed in order to evaluate heart and lung function in the preoperative period of upper abdominal and thoracic surgery can differentiate the patients who have higher chances to develop postoperative complications and which tests are more important concerning to each one intervention. The significance level considered was p
