Abstract
We aim to analyze clinical features of patients with craniocerebral trauma after 2008 Sichuan earthquake in China. Medical records of patients with craniocerebral trauma admitted to Department of Neurosurgery in West China Hospital within 30 days after earthquake were retrospectively analyzed. Demographic data, clinical diagnosis, treatment, and prognosis were reviewed. Patients' data from peripheral hospitals were also analyzed. Two hundred forty-two patients with craniocerebral injuries were included in the study. The male to female ratio was 1.3:1, and more than half of the patients were between 20 and 60 years. Majority of patients suffered from mild to moderate injuries (88.4%). Scalp wound was the leading type, followed by skull fractures and brain contusion and laceration. Fifty patients (20.7%) underwent craniotomy. Overall mortality was 5.4% (n = 13). In survivors, 186 patients had good outcome (Glasgow Outcome Scale score ≥4, 76.9%). Staphylococcus aureus (n = 74, 44.6%), Aerobacter cloacae (n = 37, 22.3%), and Staphylococcus epidermidis (n = 33, 19.9%) were most frequently isolated bacteria in wound smear. Over 85% (n=6) of patients with infectious wound (n=7) obtained delayed first stage healing. Mortality of patients in local hospitals ranged from 3.8% to 8.9%. Most patients admitted to tertiary hospitals are mildly or moderately injured. Cooperation among different departments is critical to shorten delay in emergency room. First stage wound healing or delayed first stage healing can be achieved in most patients after treatment. More than 76% of seismic injury patients in a tertiary medical center have good outcome.
