Evaluation of Clinical Signs for Diagnosis of COVID-19 in Patients Undergoing Elective Surgery

Abstract

Objective: this study tends to evaluate the clinical signs for diagnosis of covid-19 in patients undergoing elective surgery.

Methods: This is a case-control study. Patients undergoing elective surgery who tested positive for covid-19 infection based on a chest CT were considered as the case group and, if negative, were considered as the control group.All patients underwent a thorough examination before surgery and their clinical and demographic information was recorded in a designed checklist. Data were analyzed using chi-square test and SPSS software version 22.

Results: Clinical symptoms including fever, dry cough, sputum cough, dizziness, sore throat and anorexia are significantly higher in patients with Covid-19 than non-Covid-19 patients (P<0.05). There was a significant difference between laboratory findings including WBC, ALT, AST and CRP in patients with Covid-19 and non-Covid-19 patients (P<0.05).There was no significant difference between laboratory findings including Plt, PT, BUN, Cr and urinary protein in patients with Covid-19 and non-Covid-19 patients (P<0.05).

Conclusion: There is a difference between clinical signs and laboratory findings of patients with Covid-19 and non-Covid-19 patients and can be helpful in diagnosis and treatment of Covid-19 disease.
