ABSTRACT
Objective:To explore the teaching effect of PBL combined with "B-E-D-S-I-D-E" bedside teaching mode in clinical teaching of Otolaryngology nursing interns.Methods:From August 2016 to July 2018, 85 nursing students internship in Otolaryngology were selected as the research object. The nursing students were divided into control group and observation group according to the random number table method. PBL combined with "BEDSIDE" bedside teaching mode. After the internship, the teaching effect of the internship nurses, such as the evaluation of the theory of course preparation, the performance of operation, the satisfaction degree of teaching effect and the comprehensive ability of clinical nursing, was evaluated. The evaluation of mini-cex was used to evaluate the comprehensive ability of clinical nursing of nursing students.Results:The theoretical scores of nursing students in the observation group was 82.42±5.43 and the operational score was 81.83±4.51. The theoretical score of nursing students in the control group was 78.90±5.96 and the operational score was 74.84±6.14. The scores of nursing students in the two groups were significantly different ( t value was 2.844, 5.973, P < 0.01). The satisfaction of nursing students in the two groups was significantly higher than that in the control group ( t value was 4.224, 10.593, P<0.01). The scores of nursing measures, nursing diagnosis, nursing physical examination, nursing consultation, humanistic care, organizational efficiency, health consultation and overall evaluation in the mini clinical exercise evaluation scale of nursing students in the two groups were significantly higher than those in the control group ( t value was 3.483-9.070, P<0.01). Conclusions:PBL combined with "B-E-D-S-I-D-E" bedside teaching method could significantly improve the comprehensive ability of nursing students in clinical nursing practice, and also improve clinical teaching quality and satisfaction, which is suitable for promotion.
ABSTRACT
OBJECTIVE To evaluate the effect of intravenous infusion of methylprednisolone on postoperative recovery and complications after coblation tonsillectomy.METHODS Eighty three patients who were scheduled for coblation tonsillectomy from December 2015 to December 2016 were included in this study.Firstly,they were divided into 2 groups,i.e.,the younger group (＜12 years) and the older group (≥12 years old).Secondly,these two groups were further divided into experimental group and control group by the prospective,double-blind and randomized method.The experimental group was treated with methylprednisolone and antibiotics for 3 days.Then,the postoperative reactions such as the pain,activity,pharyngeal edema,body condition,exfoliation time of the tunic albuginea,post-tonsillectomy hemorrhage were observed.RESULTS 1.From the third day to fifth day,using methylprednisolone can alleviate pain (Z=4.42,P=0.00),increase the activity(Z=2.64,P=0.00)and reduce pharyngeal edema(Z=2.84,3.10,all P=0.00) in younger group.2.After operation,in the younger group,the incidence rate of gastrointestinal discomfort in control group was higher than that in experimental group(x2=4.97,P=0.03).In the older group,the incidence rate of gastrointestinal discomfort(x2=5.24,P=0.02) and sleep disturbance(x2=5.03,P=0.03) in control group was higher than those in experimental group.3.In the older group,exfoliation average time of the tunic albuginea in experimental group was longer than that in control group(t=2.16,P=0.04).4.Secondary bleeding rate was not statistically significant in the two groups(x2=1.29,P=0.26).CONCLUSION Intravenous infusion of methylprednisolone after coblation tonsillectomy is beneficial,especially in the relief of pain,gastrointestinal discomfort and pharyngeal edema.
