Background And Aims:
Post the second wave of COVID-19 in India, our institute became a dedicated center for managing COVID-19-associated mucormycosis (CAM), but there was a paucity of data regarding perioperative considerations in these patients. The objectives of present study was to describe the preoperative clinical profile, the perioperative complications and outcome of CAM patients undergoing urgent surgical debridement.
Material And Methods:
This prospective observational study was conducted on CAM patients presenting for surgical debridement from July to September 2021. During preoperative visits, evaluation of extent of disease, any side effects of ongoing medical management and post-COVID-19 systemic sequalae were done. The details of anaesthetic management of these patients including airway management, intraoperative haemodynamic complications and need for perioperative blood transfusion were noted.
Results:
One hundred twenty patients underwent surgical debridement; functional endoscopic sinus surgery (FESS) was carried out in 63% of patients, FESS with orbital exenteration in 17.5%, and maxillectomy in 12.5%. Diabetes mellitus was found in 70.8% and post-COVID new onset hyperglycemia in 29.1% of patients. Moderate-to-severe decline in post-COVID functional status (PCFS) scale was observed in 73.2% of patients, but with optimization, only 5.8% required ICU management. The concern during airway management was primarily difficulty in mask ventilation (17.5%). Intraoperatively, hemodynamic adverse events responded to conventional treatment for hypotension, judicious use of fluids and blood transfusion. Perioperatively, 10.8% of patients required blood transfusion and 4.2% of patients did not survive. Non-surviving patients were older, with a more aggressive involvement of CAM, and had comorbidities and a greater decline in functional capacity.
Conclusion:
A majority of patients reported a moderate-to-severe decline in PCFS that required a preoperative multisystem optimization and a tailored anesthetic approach for a successful perioperative outcome.
