Abstract
Background: Hemodynamic instability, which is an independent predictor of long-term patient morbidity and duration of stay in the hospital. Multiple factors contribute to the development of intraoperative hemodynamic instability. Prevention and treatment of hese factors may reduce patients’ hemodynamic change,and its associated morbidity and mortality.associated factors were blood lose ,co -existing disease ,type of procedure, age and duration of surgery.
Objectives: This study aims to assess the magnitude and associated factors of intra-operative hemodynamic change in patients undergoing elective thoracic surgery in TASH, Menilik II referral hospital, and SPSH 2023.
Methods: The Institutions-based multicenter cross-sectional study was conducted from 1/2/2023/ to April 30/2023, using -pre-tested, Interviewer questionnaires for 185 patients. This study used a systematic random sampling technique to select the appropriate participant which Selects the sample the regular intervals based on sampling fraction (K). The data was entered into Info 7.2.1 and analysed by SPSS version 26 software performed descriptive statistics and, bivariate and multivariate logistic regression.
Result: According to this study, there is a higher magnitude of Intra-operative hypotension which was found to be 40.8% (95%CI: 33.8%-48.2%). Intra-operative blood loss, type of procedure, and pre-existing co-morbidity were positively associated with intra-operative hypotension.The pre-existing co-morbidity like hypertension associated with intra-operative hypertension,the magnitude was found to be 14.4%(95%CI: 8.9%-19.1%).The age and the duration of surgery were associated with intra-operative tachycardia. Overall, the prevalence was 16.6%( 95%CI:10.67%-21.33%).The type of procedure were strongly associated with intra-operative bradycardia. Overall, the magnitude was found to be 14.4%(95%CI:8.9%-19.1%).
Conclusion and recommendation:The magnitude of intrao-perative hypotension is high. Some of the identified factors were Blood loss > ABL and the type of diagnosis. Therefore early anticipation and preparation for intraoperative hypotension especially for patient undergoing lung resection and risk of increased blood loss can improve patient
