Objective To determine the optimal suetioning negative pressure based on various sputum viscosity in brain-in-jured patients with tracheotomy. Methods Forty-three traumatic brain-injured patients with traeheotomy were recruited in the study. The negative pressure was determined based on the grade of sputum viscosity. Grade Ⅰ sputum was suetioned with the negative pressure of 13.3kPa,16.0kPa,20.0kPa and 24.0kPa, while Grade Ⅱ sputum with 20.0kPa,24.0kPa,26.TkPa and 29.3kPa,and Grade Ⅲ sputum with 26.7kPa,29.3kPa, 33.3kPa and 37.2kPa. The oxygen saturation(SpO2)was mort-itored before and lmin,3min,5min after endotracheal suctioning. At the same time,the suctioning time and tissue trauma were recorded. The data were analyzed by repeated measures analysis of variance with SPSS 13.0 software. Results The results showed that the optimal negative pressure was 13.3-16.0kPa for grade Ⅰ sputum,24.0-26.7kPa for grade Ⅱ sputum and 33.3kPa for grade Ⅲ sputum,which could ensure the minimum decrease of SpO2 and control the suctioning time within 25s or 30s respectively. Conclusion For traumatic brain-injured patients,varions negative pressure should be selected based on the sputum viscosity by the clinical nurses when suctioning is performed,in order to avoid hypoxemia and tissue trauma caused by suctioning.

OBJECTIVE To investigate and analyze the incidence and related factors of nosocomial infection in old inpatients with cancers during radiotherapy and chemotherapy.METHODS Retrospective surveys of nosocomial infection were carried out in 236 old inpatients with cancers from Jan 2005 to Oct 2008.?2 Test was used to evaluate the difference significance of the data.RESULTS The surveys indicated the infection rate was 44.36% and without the sex difference.The infection rate among old inpatients with lung cancer was the highest and counted for 69.39% and then with radiotherapy and chemotherapy that was 56.96%.Respiratory infection was the main infection and counted for 51.27%.The hospital stay time correlated well with the infection rate of the inpatients.With the hospital stay time increasing,the infection rate also increased.Moreover,the predisposing factors of inpatients infection included poor nutrition,advanced stage of tumors,aggressive procedures,leukopenia and application of antibiotics.CONCLUSIONS The nosocomial infection rate of old inpatients with cancers during radiotherapy and chemotherapy is much higher than that of the elders with common diseases and that of the youngers with cancers.The incidence of nosocomial infection is related to the sites of the primary cancers,therapy methods,hospital stay,etc.We must emphasize and control the predisposing factors effectively,and reduce the occurrence of nosocomial infection.
