Analysis and Differences of the Neurosurgical Complications During COVID-19 Pandemic.

Objectives: The objective of the study was to analyze the complications of neurosurgical operations during the COVID-19 pandemic by comparing them with the complications observed in the pre-pandemic period. Methods: Two groups were formed: (1) Patients who were operated in the 5-month period of the pandemic (March-July 2020) and (2) those who were operated the same operations in the same period 1 year before (March-July 2019). Demographics, characteristics, medical follow-up data, complications, and outcome compared between the groups. Results: Similar demographics were observed between the groups. The number of all neurosurgical cases and neurotrauma cases decreased by 79% and 68% in pandemic period, respectively. The rate of emergency surgeries was significantly higher in pandemic group (p<0.001). The operation time was significantly longer in pandemic group (p=0.014). Total complication rate was significantly higher in pandemic group (p=0.002). Specifically, the rate of pulmonary complications was significantly higher during pandemic period (p<0.001). The infection rate (p<0.001), antibiotic use (p<0.001), and intensive care unit stay (p=0.023) were significantly higher in pandemic group. Conclusion: During pandemic period complication rates increased and a higher risk than expected was encountered. Treatment should be performed by taking the precautions and informing the patients about additional risks.
