Risk factors for lung infection after cerebral hemorrhage: a retrospective study / 中华物理医学与康复杂志

ABSTRACT

Objective:To observe risk factors for lung infection (LI) after cerebral hemorrhage (ICH).Methods:A total of 118 patients with ICH were retrospectively analyzed. Among them, 63 were diagnosed with an LI according to clinical manifestations and X-ray or CT on admission. They were selected into an LI group, while the rest formed the non-LI group. Gender, age, duration of disease, side of paralysis, position and type of ICH, complications, cognitive disorders, consciousness, dysphagia, motor function, and serum levels of albumin, sodium, potassium, calcium and magnesium were recorded on the second day after admission. The risk factors for LI were analyzed using univariate and multivariate logistic regression analysis.Results:Age, duration of disease, side of paralysis, position and type of ICH, tracheotomy, urinary tract infection, cognitive impairment, dysphagia, motor function, and serum levels of albumin, sodium, calcium, and magnesium were all significant predictors of LI after an ICH. Multivariate logistic regression analysis showed that right side hemiplegia, bilateral paralysis, subarachnoid hemorrhage, urinary tract infection, and serum magnesium are all significant predictors.Conclusions:Right or bilateral paralysis, subarachnoid hemorrhage and urinary tract infection are independent risk factors for LI after an ICH. High serum magnesium within the normal range can reduce the incidence of LI.
