Objective To investigate the risk factors of incisional wound infection and put forward prevention measures to control the incision infection in patients under craniectomy.Methods Seventy patients with infection and 70 without infection of incisional wound among 1756 patients undergoing craniectomy from January 2011 to December 2013 were chosen in our study;and their clinical data were retrospective analyzed;etiological examination was performed on the secreta of these patients;the high risk factors of incisional wound infection were analyzed using multivariable Logistic regression.Results As compared with those in the non-infection group,patients in the infection group had significantly older age,lower albumin and Glasgow coma scale (GCS) scores,higher blood glucose level and APACHE Ⅱ scores,and higher percentages of surgical access station,microscopy applications,duration of surgery＞4 h and blood transfusion (P＜0.05).Pathogenic bacteria was positive in 88.57％ patients (62/70),including 45.71％ gram negative bacilli,40.00 ％ gram positive coccus and 2.86％ fungus.Multivariate Logistic regression analysis further showed that albumin,blood glucose,microscopy applications,duration of surgery＞4 h,blood transfusion,APACHE Ⅱ scores and GCS scores were significantly associated with incision infection,being the independent risk factors for incision infection.Conclusions To aim directly at the high-risk factors of incision wound infection,such as albumin,blood glucose,microscopy applications,duration of surgery,blood transfusion,APACHE Ⅱ and GCS,we should develop reasonable and effective preventive measures to reduce the incidence of incision infection and improve patient prognosis.

Objective To investigate the abuse tendency of disabled elderly caregivers and analyze its causes.Methods With the convenience sampling method,The main caregivers of 300 disabled elderly people were investigated by the general questionnaire, Activities Daily Living Scale (ADLs) and Caregiver Abuse Screen (CASE) in Guangzhou. Results The degree of disability of the elderly was moderate to severe degree.The average score of the elderly caregiver′s propensity for abuse tendency was(3.3 ± 2.3).178 (59.4 %, 178/300) of the elderly caregivers have abuse tendency (the average score was more than 3). Conclusion Caregivers′ abuse tendency against the elderly is high. The situation of the elderly is not optimistic.
