Analysis on risk factors for intracranial infection after craniotomy for resection of skull base neoplasms

Abstract

Objective To analyze the relevant risk factors for intracranial infection after craniotomy for resection of skull base neoplasms. Methods The clinical data of 159 patients with skull base neoplasms who underwent craniotomy from May 2010 to January 2020 in The Second Affiliated Hospital of Anhui Medical University were analyzed retrospectively. The relevant risk factors for intracranial infection were analyzed by univariate and multivariate forward Logistic regression. Results Postoperative intracranial infection occurred in 81 out of 159 patients, the infection rate was 50.94%. Multivariate forward Logistic regression analysis showed the operation time was ≥ 5 h (OR = 3.438, 95%CI: 1.371-8.625; P = 0.008), blood loss ≥ 400 ml (OR = 2.308, 95%CI: 1.115-4.777; P = 0.024), frontal sinus or mastoid air chamber breach (OR = 16.817, 95%CI: 3.689-76.658; P = 0.000) were the risk factors for intracranial infection after craniotomy for resection of skull base neoplasms. Conclusions There was a higher risk of intracranial infection after craniotomy for resection of skull base neoplasms in patients who had long operation time, more intraoperative blood loss as well as frontal sinus or mastoid air chamber breach. It is necessary to adopt effective prevention and control measures to reduce the risk of intracranial infection.
