ABSTRACT
Objective To study the clinical effect of chlorhexidine acetate solution for oral care in patients with endotracheal intubation. Methods From February 2017 to August 2017, 160 patients with tracheal intubation in our department were divided into the observation group (80 cases) and the control group (80 cases) by random number table method. The observation group was treated with chlorhexidine acetate solution, and the control group used the compound Borax solution for oral care. The oral condition score, the positive rate of oral bacterial culture, the incidence rate of ventilator-associated pneumonia were compared between two groups. Results In the observation group, the oral condition score and the positive rate of oral bacterial culture were 10.29 ± 2.04 and 16.25% (13/80) on the 3rd day after theoral care. In the control group, the oral condition score and the positive rate of oral bacterial culture were 12.79 ± 1.97 and 31.25%(25/80) on the 3rd day after the oral care. There were statistically significant differences between the two groups (t=-7.895, P<0.01; χ2=4.970, P<0.05). The incidence and occurrence time of ventilator-associated pneumonia in the observation group were 7.50% (6/80), (9.33±1.37) d. The incidence and occurrence time of ventilator-associated pneumonia in the control group were 18.75% (15/80), (5.87 ± 1.06) d. The difference between the two groups was statistically significant (χ2=4.440, P<0.05; t=6.248, P<0.01). Conclusions The chlorhexidine acetate flushing oral care can significantly improve dental status, reduce the positive rate of oral bacterial culture and the incidence of ventilator-associated pneumonia, and prolong the occurrence time of ventilator-associated pneumonia in patients with endotracheal intubation.
ABSTRACT
Objective To explore the effects of problem-based bedside nursing teaching in clinical teaching. Methods Totally 247 college nursing students were recruited in the study from July 2016 to June 2017. The 118 students were in the experimental group which implemented problem-based bedside nursing teaching,while 129 students were in the control group which implemented traditional teaching.The teaching effects of two groups at the end of practice was compared with mini-CEX. Results The clinical nursing comprehensive ability of the experimental group was 6.42±1.45,the control group was 5.25±1.35,the difference was statistically significant(t=15.73,P=0.000).The clinical teaching effect of the experimental group was better than that of control group,41.53%(49/118)and 51.69%(61/118)met the requirements and reached excellence, and 62.79%(81/129)and 19.38%(25/129)in the control group.The difference was statistically significant (Z=-5.35, P=0.000). Conclusions The model of bedside teaching based on problem can significantly improve nursing students'clinical nursing comprehensive ability and improve clinical teaching effect.
