Objective To study the cognitive behaviors of ICU nurses about cluster intervention strategies of central venous catheter blood infection.Methods Two hundred and two ICU nurses were involved in the survey using self-designed questionnaire.Results The scores on knowledge of ICU nurses with cluster intervention strategies was(31.9±2.8)and the score on the cognitive behaviors was(26.9±2.6). Conclusions The ICU nurses’knowledge on cluster intervention strategies is at a general level and their behaviors are at the status ofseldomorsometimes.Therefore,improvement of manipulation flowsheet,control of routes for bacterial infections and enhancement of knowledge learning are critical for the improvement of cognitive behaviors of ICU nurses with cluster intervention strategies.

Objective To investigate the effect of restriction decision wheel and grade ICU patients with critical consciousness disorder. Methods Two hundred and fifty four patients in ICU with critical consciousness disorder from July to December 2012, who were intubated and constrained with their limbs due to the risk of unexpected extubation, were divided into the control group (n=125) and the experiment group (n=129), according to registration sequence. The former were constrained to their limbs after evaluation referring to the constraint nursing form and the latter was constrained by using the constraint decision-making wheel and grade. The two groups were compared in terms of restraint rate, unplanned extubation rate, and incidence of skin abnormality. Results The restraint rate of the observation group was significantly lower than that of the control group (P<0.01). There was no incidence of abnormal skin in the two groups. There was no significance in the rate of unplanned extubation between the two groups (P>0.05). Conclusion Constraints decision making wheel and grade is effective in ensuring patients'safety and improving the quality of nursing safety management by reducing unnecessary constraints or the incidence of delayed constraints.

Objective To explore the effect of multifunctional rehabilitation wheelchair on early rehabilitation of elderly patients after anesthesia recovery with hip fracture surgery.Methods Toally 34 elderly inpatients with hip fracture surgery treated with regular function exerciser between November 2013 to October 2014 were assigned as the control group and another 34 elderly inpatients with hip fracture surgery during November 2014 and November 2015 as the observation group.The control group was treated with routine nursing and early on-bed rehabilitation exercise and the latter with early off-bed exercises on a muhifunctional wheelchair.The two groups were compared in terms of hip function and daily life activities ability before surgery and 14 d after operation.Result The Harris hip function cores and activities of daily living scores of the observation group after surgery were significantly higher than those of the control group (P ＜0.05).Conclusion Multifunctional rehabilitation wheelchair can be effective in the improvement of the hip function and daily life activities for the elderly patients with hip fracture surgery.

Objective To investigate the value of prognosis of NT-proBNP in severe sepsis and septic shock patients .Methods 70 patients with sepsis admitted to our hospital were divided into general sepsis group (n=23) ,severe sepsis group(n=28) and sep-tic shock group(n=19) according to the severity of the disease ,the plasma NT-proBNP ,lactic acid ,C-reactive protein were meas-ured within 1 h after admission ,and calculated the 24 h acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) .Results (1) Plasma NT-proBNP concentration ,lactic acid ,CRP and APACHE Ⅱ score in severe sepsis group ,septic shock group was sig-nificantly higher than that of general sepsis group(P< 0 .05);Plasma NT-proBNP concentration ,CRP and APACHE Ⅱ score in septic shock group was significantly higher than severe sepsis group (P<0 .05) .(2)70 cases of patients with sepsis with 15 cases died and 55 cases survived .Plasma NT-proBNP concentration ,lactate ,CRP and APACHEⅡscore of death patients was significantly higher than the survival patients(P<0 .01) .(3) Plasma NT-proBNP concentration at the time of sepsis patients admitted to hospi-tal with positively correlated to APACHE Ⅱscores(r=0 .528 ,P<0 .01) .Conclusion The plasma NT-proBNP is closely related to the prognosis of patients with sepsis ,early detection of plasma concentration of NT-proBNP helps to evaluate the prognosis of pa-tients w ith sepsis .
