ObjectiveTo analyze the effect of noninvasive positive pressure ventilation (NPPV) on the treatment of severe acute pancreatitis (SAP) combined with lung injury [acute lung injury (ALI)/acute respiratory distress syndrome (ARDS)] in emergency treatment. MethodsFifty-six patients with SAP combined with ALI/ARDS treated between January 2013 and March 2015 were included in our study. Twenty-eight patients who underwent NPPV were designated as the treatment group, while the other 28 patients who did not undergo NPPV were regarded as the control group. Then, we observed patients' blood gas indexes before and three days after treatment. The hospital stay and mortality rate of the two groups were also compared. ResultsBefore treatment, there were no significant differences between the two groups in terms of pH value and arterial partial pressure of oxygen (PaO2) (P>0.05). Three days after treatment, blood pH value of the treatment group and the control group was 7.41±0.07 and 7.34±0.04, respectively, with a significant difference (P＜0.05); the PaO2 value was respectively (60.60±5.11) and (48.40±3.57) mm Hg (1 mm Hg=0.133 kPa), also with a significant difference (P＜0.05). The hospital stay of the treatment group and the control group was (18.22±3.07) and (23.47±3.55) days with a significant difference (P＜0.05); and the six-month mortality was 17% and 32% in the two groups without any significant difference (P>0.05). ConclusionIt is effective to treat patients with severe acute pancreatitis combined with acute lung injury in emergency by noninvasive positive pressure ventilation.
ObjectiveTo explore the risk factors for multiple nosocomial infection in adult hospitalized patients, so as to provide references for the control of nosocomial infection. MethodsThe clinical data of adults hospitalized patients with nosocomial infection in the Second Affiliated Hospital of Fujian Medical University during Jan. 2015 to Dec. 2015 were collected, and the susceptible factors of multiple nosocomial infections referencing to the single nosocomial infection were analyzed. Results1226 cases (1368 case-times) of nosocomial infection were found and the infection rate and the case-time infection rate were 2.24% and 2.49%, respectively. Single factor analysis results showed that the top four risk factors of multiple nosocomial infection included hospital stay ≥30 days (25.5%), first infection time ≥30 days (23.2%), incision type Ⅲ (16.7%), and surgery (13.4%). Logistic regression analysis result showed, after adjusting the influence of age and gender, longer hospital stay was the independent risk factor of multiple nosocomial infection referencing to single nosocomial infection (OR=3.475, 95%CI 2.545 to 4.745). ConclusionLonger hospital stay is the independent risk factor of multiple nosocomial infection of adult hospitalized patients. Measures should be taken to shorten the length of stay in hospital and reduce the exposure to the high-risk environment, so as to reduce the incidence of multiple nosocomial infection.
