Objective To observe the application effect of the Iodophors hygro-gauze on tracheotomy wound dressing. Methods Fifty patients who underwent tracheotomy with Ⅲ incision, were chosen to be divided into the control group and the observation group with 25 in each group. With saline water cleaning incision and surrounding skin, then disinfection with 0.5% iodophors sanitizers tampon. The observation group applied 0.5% Iodophors hygro-gauze on the wound, the control group used vaseline oil yarn. 24 hours after sample inspection, again samples were sent for bacteria analysis, bacterial colonies number, pathogenic bacteria growth and local situation of wound were observed and analyzed. Results The first results upon disinfection showed that bacterial colonies number, pathogenic bacteria growth between the two groups had no difference. After 24 hours sampling showed that the colony count and pathogenic bacteria growth of the observation group was obviously less than the control group. Local wound infection of the observation group was lighter than the control group. Conclusions 0.5% Iodophors hydro-gauze applied for tracheotomy wound dressing can effectively kill various pathogenic microorganism, prevent secondary infection, and also can prevent and treat wound infection.

Objective To discuss the method to increase the success rate of stomach tube insertion for patients with indwelling nasotracheal tube in order to shorten the time of insertion operation and reduce the discomfort of patients.Methods Seventy patients with nasotracheal tube were randomly divided into the observation group(38 cases)and the control group(32 cases).When the operator for the observation group inserted stomach tube to 18～22 centimeters deep,the nurse pumped the gas out from the tracheal catheter aerocyst.After the stomach tube reached stomach the tracheal catheter aerocyst was aerified again.The control group did not release the gas from tracheal catheter aerocyst when inserting the stomach tube.The first intubation success rate and time needed for intubation were compared between the two groups.Results The first intubation success rate of the observation group was higher than that of the control group(P＜0.05).While the time needed for intubation was shorter than that of the control group(P＜0.01).Conclusions Method used by the observation group not only increased the first intubation success rate,but also shortened time needed for intubation.This method can alleviated pain of patients and worth applying widely in clinic.

AIM: To evaluate the effect of hyaluronate based gel (HAbg) in prevention of pleural thickening and adhesion in patients with tuberculous pleural effusions. METHODS: 52 patients with middle amount of tuberculous thoracic fluid accumulated, fluid bound, and pleura thickened more than 2 mm were divided into two groups at random. The patients of two groups were all given standard treatments with anti tuberculous drugs. HAbg was injected into intra thoracic cavity in treatment group (27 patients), while saline (NS) was introduced into intra thoracic cavity in control group (25 patients). Before and after HAbg injection, thoracic fluid routine and protein quantification were tested respectively. Pulmonary functions were measured after 2 weeks and 3 months of thoracic fluid absorption. RESULTS: Patients treated with HAbg showed significantly thinner pleura, lower proteins and white blood cell count in thoracic fluid, and higher FEV1% and FVC% for their pulmonary function in comparison with the control group. CONCLUSION: Intrathoracic injection of HAbg can prevent pleural thickening and improve the lung function in patients with excess fluid of tuberculous thoracic cavity.

AIM: To investigate the effects and safe of low molecular weight heparins (LMWH) in the treatment of patients with chronic pulmonary heart diseases (CPHD) at hypercoagulability state. METHODS: 65 patients were randomly assigned to treatment group (n=33) and control group (n=32). All patients were given routine treatments. The patients of treatment group were hypodermically injected with 4 100～6 150 U of LMWH per day for 7 days as a course. RESULTS: After 7 days of the treatments, the patients of treatment group showed better curative effect and significantly increase in PaO_2 and AT-III and decrease in PaCO_2 and FIB in comparison with the patients in control group (P

Objective To explore the influence of the health belief model education on the life quality of nurses.Methods 200 nurses were randomly divided into the experimental group and the control group with 100 cases in each,the experimental group received health belief model education while the control group was given no intervention.The life quality of nurses before and after the education was compared.Results The life guality of nurses showed no significant difference between the two groups before the health belief model education,one month after health belief model education,life quality of nurses in the two groups showed significant difference.Conclusions Application of the health belief model education can improve the nurses'quality of life.

Objective To observe the nursing efficacy of cluster-based care for bronchial asthma.Methods 100 cases with bronchial asthma were randomly divided into the study group and the control group with 50 patients in each group.The control group received usual care,and the study group received cluster-based care model.Curative effect,the total of the cases received inhalation therapy correctly,compliance of inhalation therapy,degree of satisfaction to nursing services in the two groups were compared.Results The curative effect in the study group were better significantly than the control group (86％ vs 58％).The cases received inhalation therapy correctly in the study group were more than the control group (92％ vs 72％).The compliance of inhalation therapy in the study group was significantly higher than the control group(90％ vs 80％).The degree of satisfaction to nursing services in the study group were significantly higher than the control group (98％ vs 86％).Conclusions Cluster-based care had good effect on patients with bronchial asthma.
