Main Article Content
Abstract
Background: ASA-PS classification has been applied to surgical patients all over the world preoperatively. The 2019 Amended ASA-PS was modified by new definitions, approved examples, especially definition for emergent patients. In Vietnam, there has not any independent study on ASAPS classification up to now. Objectives: determine the ratio of patients of each ASA class and determine patients’ underlying diseases. Materials and methods: This was a cross-sectional descriptive study, the sample size was ≥ 380, and the sampling method was convenience sampling. Results: There were 528 patients of both 5 emergent and elective operations included. The ratio of ASA were I (39.21%), II (33.52%), III (17.42%), I-E (6.06%), II-E (3.03%) and III-E (0.76%). None of the cases was classified as ASA IV/IV-E, V/V-E or VI. The most common patients’ health conditions were social alcohol drinker and current smoker. The most popular underlying diseases were diabetes mellitus, obesity, hypertension, cardiovascular diseases, mild respiratory diseases (history of asthma or pulmonary tuberculosis) and COPD. Conclusions: The ASA ratio were I (39.21%), II (33.52%), III (17.42%), I-E (6.06%), II-E (3.03%) and III-E (0.76%). Patients might have more than one health condition or underlying disease by pre-operative evaluation.
