COVID-19-associated mucormycosis: an update of anesthetic management

Abstract

BackgroundMucormycosis is uncommon, progressive fungal infection with mortality rate on higher side. The anesthetic management of surgical debridement in mucormycosis is challenging.We evaluated the anesthetic management of mucormycosis patients associated with problems of airway management, predisposing factors, and adverse effect of antifungal therapy who underwent surgical resection of necrotized tissues.ResultsFifty-six patients presented with uncontrolled diabetes mellitus. All patients had history of COVID-19 infection and received steroid during treatment. Nasal endoscopic debridement was done in 43 patients, total maxillectomy in 14 patients. Temporalis flap was needed in five patients, and orbital exenteration was required in three patients. Central venous catheter was inserted in 17 patients, and invasive arterial monitoring was done in ten patients. All patients administered lyophilized amphotericin B (deoxycholate) in combination with surgical debridement.Thirteen patients were shifted to ICU for further management and continuous hemodynamic monitoring. Fifteen patients were expired, and the mortality rate was 26.31%.ConclusionsChallenges include difficult intubation and renal function impairment due to prolonged antifungal therapy. Postoperative ICU management is important in mucormycosis patients due to comorbidities and rapid progressive infection after surgery.
