Objective To evaluate the predictive effect of Braden scale for the risk of development of pressure ulcers (PU) in the department of neurology bedridden patients and to explore subgroup preventive measures. Methods 400 cases newly hospitalized bedridden patients in the department of neurology were collected with no pressure ulcers at the first evaluation and pressure ulcer risk was continuously predicted by a Braden scale skin assessment. The high-risk, middle-risk and low-risk groups were randomized into the experimental group and the control group respectively. Routine preventive measures were taken for the control group while the air fluidized bed for the high-risk group, the sponge mattress for the middle-riskgroup, and turning the body over every 4 hours for low-risk group. Other preventive procedures were undertaken simultaneously in beth the experimental and the control groups. Results The area under the ROC curve (AUC)was 0.771 and 0.828 at the first and last time Braden scale scores respectively. Such vMues as sensitiveness, specificity, positive predictive value, negative predictive value were found in higher level,when the diagnosis value was 17. There was no significant difference of incidence rate of the subgroup pressure ulcers between the high-risk, middle-risk, low-risk groups compared to the control group. Conclusions The effect of predicting pressure ulcer risk for bedridden patients in the department of neurology with Braden scale was fairly good, while the score 17 as the diagnosis value was ideal. The air fluidized bed for the high-risk group and the sponge mattress for the middle-risk group resulted in no significant decrease of incidence rate of the pressure ulcer, while taming over the patients' body every 4 hours for low-risk groups showed acceptable and therefore saving medical resources.

Objective To explore the main cause of displacement of peripherally inserted central catheters ( PICC) among pediatric patients with hematologic disease .Methods Eleven nurses and 10 children's parents received the questionnaire on the cause analysis of displacement of PICC among pediatric patients with hematological tumor which was made through the analytical hierarchy process theory , the literature review and interview.The weight of each indicator was calculated in the two groups , and the indicator was put in the right order according to their weights .Results The top 4 main causes agreed by nurses and parents in the displacement of PICC among pediatric patients with hematologic disease were respectively poor supervision C 6 , non-standard dressing methods C 1 , different adhesive forces of dressings C 15 , excessive activity of arm in where the PICC line was located C 9 , and the predominant reason was the poor supervision C 6 .Conclusions We should strengthen the training of nurses , and choose the appropriate dressings , and enhance the guard consciousness of the displacement of PICC in children's parents , and reinforce the supervision , and reduce the arm activity so as to decrease the displacement of PICC among pediatric patients with hematologic disease .
