Evaluation of Hemodynamic Status of the COVID-19 Patients Under Anesthesia

Abstract

Background: The COVID-19 pandemic has encouraged an unprecedented number of publications on epidemiological, pharmacological, immunological, and medical issues. Studies have also been performed on hemodynamic changes in the patients admitted to different wards. Objectives: This study aims to determine the hemodynamic status of the COVID-19 patients under anesthesia. Methods: In this cross-sectional analytical study of the two groups, 40 patient candidates for surgery and general anesthesia in the hospital were enrolled in the study based on the inclusion criteria, after signing written informed consent. The patient’s demographic information was obtained from the patient’s file and oral interview. Then, non-COVID-19 patients and patients with COVID-19 definitive tests were followed during the operation. During surgery, hemodynamic factors including pulse, blood pressure, SpO2 and respiration were monitored and recorded by a monitoring device. SPSS software version 19 was used to analyze the data. Results: The mean ± SD of patients’ age was 47.55 ± 21.37. The data showed that systolic blood pressure before anesthesia and pulse before and during anesthesia in the COVID-19 group was significantly higher than that in the non-COVID-19 group (P < 0.05). Also, respiration and SpO2 before anesthesia were lower in the COVID-19 group than in the non-COVID-19 group (P < 0.05); while respiration and SpO2 during anesthesia were not significantly different between the two groups (P > 0.05). In the COVID-19 group, systolic blood pressure, pulse, and respiration during anesthesia were significantly lower than before anesthesia and conversely, SpO2 was higher (P < 0.05). Conclusions: The findings of the present study showed that patients who do not have severe COVID-19 and serious clinical symptoms do not go through severe hemodynamic changes during surgery. Therefore, it can be said that in emergencies, surgery can be performed by observing standard principles. However, more research is needed in this regard.
