Objective:In order to reduce the incidence of infection and disablement,and increase the efficiency of wound flushing and debriding,the irrigating pressure of firearm wound was designed.Methods Canine models wounded with gunshot at the limbs were established.Two irrigating methods,including meddling irrigating pressure and high irrigating were used to irrigating wound,respectively.General observation,optical microscopy and quantitative bacterial analysis were performed immediately after injured and irrigated.Results The bacteria counts after irrigating on the surface of wound are much less than those before irrigating in two groups(p

Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia worldwide with a trend of increasing morbidity and prevalence. It usually links to a high disability and mortality rate. Stroke is the most important and severe complication of AF, as a core strategy to prevent it, anticoagulation therapy is recommended to reduce the risk of stroke events. However, management risks including poor treatment adherence, individual difference and bleeding risk can′t be ignored. In the western countries, they have successively established a nurse-led integrated chronic care program for patients with atrial fibrillation. We can use it to guide our future work. Anticoagulation therapy is a long-term managing process. To integrate the existing medical resources, nurses must give their full play to access the deep needs and guide them to learn the core skills of management, thus improving the adherence to anticoagulation therapy.

Business process cost management is key to hospital business process management It mostly consists of process cost accumulation and cost analysis. The paper probed into theories of Activity Based Costing (ABC), and built a model for hospital process costing based on the hospital organizational structure Discussed herein include the items of hospital medical services and their activity costs, followed by a case study to prove ABC as practical in the analysis and calculation of hospital business process costs.

Objective To explore the best position in bed for the patients who have under the operation of percutaneous coronary intervention (PCI) and then used heparin sodium within 24 hours. Methods The 159 patients were divided into two groups randomly:the experimental group and the control group. After the PCI, the subjects in these two groups will rest in bed by two ways. Using McGill′s present Pain Index to evaluate hematoma, using the PPI to evaluate the pain of back, using the STAI to evaluate the condition of anxiety, write the number of patient who have anuresises. Results There are no significant difference between two groups in wound blooding, while the difference of back pain, anxiety and the anuresises are significant between two groups. Conclusion The position of half-lie is safe and comfortable for the patients who have under the operation of PCI.

Objective To explore the effects of home-based 6-minute walk test on self-management in patients after percutaneous coronary intervention (PCI). Methods Eighty-four patients who admitted for PCI in the past five years in Cardiovascular Medicine of Zhujiang Hospital of Southern Medical University were recruited from the three major communities and were divided into intervention group and control group by random digits table method with 42 cases each. The intervention group had the home-based 6-minute walk test and monthly telephone follow-up while the control group was followed up by telephone and keep daily activities. Six months after the intervention,the changes of chronic disease self-management in-ventory were compared. Results There were significant differences the overall health self-assessment, fa-tigue,chest pain, time of aerobic exercise, the increase of self-efficacy between intervention group and control group[ (0.62±1.28) points vs. (0.20±1.71) points, (-0.84±3.27) points vs. (0.36±2.71) points, (0.04 ±3.56) points vs. (0.34 ±3.56) points, (30.47 ±123.29) min/week vs. (6.62 ±84.82) min/week, (0.42±3.01) points vs. (-0.29±2.94) points ], and there were significant differences, F=9.15, 7.42, 5.24, 3.91, 12.18, P<0.01. But there were no significant differences for other 9 aspects between two groups (P>0.05). Conclusions Home-based 6-minute walk test can be a simple self-assessment tool used at home for patients after PCI.

OBJECTIVE To find out the clinic air disinfectant effect and the damage to human body between air aerosol sprayer of hydrogen peroxide and peracetic acid. METHODS New ninety eight sickrooms were randomly disported into two groups. The group of using peracetic acid was a control one. Then the clinic air disinfectant effect and the damage between two groups were observed. RESULTS After thirty minutes, to sample through flat exposure method. The total number of bacteria of two groups reached the third grade of environment eligible standard without pathogenic bacteria being checked. Hydrogen peroxide had not obvious mucous membrane stimulation and hypersusceptible reaction to human body. But peracetic acid had mucous membrane stimulation and hypersusceptible reaction to human body. CONCLUSIONS The air disinfection using aerosol sprayer is still an available method when there are no person in new sickrooms or extended sickrooms. At present, some chemical disinfectant methods that have strong poisonous reactions and pollute environment, such as peracetic acid, have been restricted to be used because of thrill, toxicity to human body and causticity to goods. But the method of dynamic air disinfectant machine that can be used in the situation of ventilation, dust catching, decontaminating, and ultraviolet irradiation, at the same time having someone has became a new idea of air disinfection.

OBJECTIVE To improve the accuracy of the radiant intensity detection of ultraviolet lamp and ensure its disinfection effect.METHODS At the different time after use of the ultraviolet lamp,its radiant intensity was measured by using the luminometer,and estimated.RESULTS If the ultraviolet lamp with good uality and worked one hour each day,with detected intensity ≥90 ?W/cm2,it could be used one year continuously,when ≥80 ?W/cm2,it could be used 6 months continuously,and when 80-75 ?W/cm2,it could be used 1 month continuously.The lump's detected intensity must be exceeded over 70 ?W/cm2.CONCLUSIONS The method that detecting the radiant intensity of ultraviolet lamp in scheduled time and consulting the used time of lump is viable.The method is real,simple,convenient and easy manipulated and ensures the effectiveness of disinfection by using ultraviolet lamp.

Objective To know the effects of training for community residents about cardiopulmonary resuscitation.Methods 60 community residents were trained by CPR with varied training methods,evaluated the effects by the ABC for life questionnaire.Results The knowledge of cardiopulmonary resuscitation among the trained community residents were better than before expect 4 aspects.Conclusions The knowledge of cardiopulmonary resuscitation in community residents was not enough,systemic training can effective promote their skills of CPR.

Objective To identify the suitable echocardiographic predictor,the standard 2-demensional echocardiography and speckle tracking imaging (STI) techniques were applied for the late referred children with transposition of great arteries with intact ventricular septum (TGA-IVS) after neonatal period.Methods 22 children with TGA-IVS after neonatal period were enrolled.According to the intraoperative left ventricular (LV)/right ventricular systolic pressure ratio,they received pulmonary artery banding (PAB group,n =10) or arterial switch operation (ASO group,n =12).15 body surface area matched healthy children were served as control group,Echocardiography was performed before the operation.The dynamic images in basal and apical short axis view were collected respectively.Meanwhile,using the STI technique,the rotation curves at apex and base was analyzed.Results All the patients discharged eventually.A right to left bulging of the ventricular septum was observed in all the patients by the 2D short-axis view.There were no differences in wall thickness and ejection fraction between control,PAB and ASO group.Compared with the control group,the end diastolic diameter,end diastolic volume and indexed LV mass in PAB and ASO group were significantly reduced,however,no difference in the end diastolic diameter and volume and LV mass was observed between the PAB and ASO group.The hypoplasia of LV in PAB and ASO group was associated with an extended time to peak basal rotation and reduced basal rotation and global torsion.Furthermore,the shorter time to peak apical rotation and reduced apical rotation and global torsion were only observed in PAB group.Conclusions The standard echocardiography could be useful for the initial evaluation for regressed LV of the children with TGA-IVS.However,STI allows a much more precious approach to the assessment of LV regressing after neonatal period.The apical rotation and global torsion might be the better predictor to identify the borderline or regressed LV for the surgical management for the children with TGA-IVS.
