FREQUENCY OF PERIOPERATIVE LARYNGOSPASM IN PATIENTS WITH A HISTORY OF COVID-19 INFECTION AT LADY READING HOSPITAL, PESHAWAR

Abstract

Background:  Laryngospasm is a protective laryngeal airway reflex response, which may be a partial or complete closure of the vocal cord. There are many factors such as patient-related, surgical-related, and anesthesia-related factors that cause or increase the incidence of laryngospasm perioperatively. It may be common in those patients having hyperactive airway disease such as Covid-19 infection. Objectives:  The primary purpose of the study was to determine the frequency of perioperative laryngospasm in a patient with a history of Covid-19 infection. The secondary purpose of the study was to evaluate the major factors which may increase the incidence of perioperative laryngospasm. Methods:  A cross-sectional observational study was undertaken at Lady Reading Hospital-MTI, Peshawar. The University Ethical Committee Review Board approved the study. We processed 217 samples. We got informed consent. Lab results revealed Covid-19 infection in the patient. Regular regular monitoring and SOPS were followed. Patient monitoring and questionnaire completion occurred throughout the operation. Data were analyzed using SPSS 22.0. Crosstab was used to determine the relationship between laryngospasm and numerous risk factors, while descriptive statistic frequency was produced and tabulated. Results:  Patients with Covid-19 infection had 21% preoperative laryngospasm. 95% of laryngospasms occurred during light extubation and 5% during deep. Airway irritants were identified in 6.5% of laryngospasm patients. 26% of smokers had laryngospasm. In 3% of patients, the supraglottic airway device (LMA) was employed, but laryngospasm was minimal. 97% of laryngospasm patients were induced with propofol and the rest with ketofol. Conclusion:  This study examined Covid-19-infected patients' preoperative laryngospasm rates. Evaluation of their risk variables was needed to eliminate confounding. The findings showed that COVID-19 infection is a strong risk factor for perioperative laryngospasm. COVOD-19-infected surgical patients should have all laryngospasm drugs and management options available promptly
