Abstract

Preoperative tests are a widely used practice in medical care; however, in most cases, their use is not based on the best available evidence. In order to evaluate the usefulness of preoperative studies in elective surgery in patients classified as American Society of Anesthesiologists (ASA) physical status I and II, an analytical, prospective, single-cohort study was conducted. The research included patients scheduled for low- to moderate-risk elective surgeries between January 1, 2022, and June 2023, at the Provincial General Hospital Carlos Manuel de Céspedes in Bayamo. The study population consisted of 375 patients scheduled for elective surgery during the study period; sample size was calculated using the statistical program Epi Info 7©, which yielded 184 patients. The results showed that abnormalities were more frequent in female patients, those aged 51 to 60 years, and ASA II patients, indicating a moderate surgical risk. Overall, the mean values obtained in laboratory tests remained within normal ranges. However, postoperative complications were observed in 14 patients. An association was found between surgical risk and altered hematocrit values with the occurrence of complications. It was concluded that laboratory, electrocardiographic, and chest radiological tests, except for blood glucose, were not useful in predicting perioperative complications in ASA physical status I and II patients undergoing elective surgery.
