新型鼻饲用具专利技术装置在重症脑卒中患者肠内营养中的应用

Application of patented technology of a new type of nasal feeding device for enteral nutrition in patients with severe stroke

目的观察新型鼻饲用具装置在重症脑卒中患者肠内营养中的应用效果。方法将行肠内营养的重症脑卒中患者238例随机分为观察组和对照组,每组119例。对照组采用常规方式放置鼻饲用具,观察组采用新型鼻饲装置。比较2组消化道症状、大便培养阳性率、鼻饲用注射器掉落患者比率、非计划更换鼻饲用注射器患者比率、鼻饲用注射器细菌污染情况。结果2组腹泻发生率比较,差异有统计学意义(P<0.05)。观察组大便培养阳性患者占比与对照组比较,差异有统计学意义(P<0.05)。观察组鼻饲注射器掉落及非计划更换鼻饲注射器患者比率低于对照组,差异有统计学意义(P<0.05)。使用注射器48、72 h后,对照组鼻饲注射器细菌检出阳性率高于观察组,差异有统计学意义(P<0.05或P<0.01)。观察组鼻饲操作时间短于对照组,但差异无统计学意义(P>0.05)。结论新型鼻饲用具固定架能够减少注射器细菌的滋生,降低患者腹泻的发生率,提高护理工作效率。

Objective To observe the effect of the patented technology of a new type of nasal feeding device for enteral nutrition in patients with severe stroke.Methods A total of 238 severe stroke patients receiving enteral nutrition were selected,and were randomly divided into observation group and control group,with 119 cases in each group.The control group applied conventional method to place nasal feeding materials,and the observation groups used a new type of nasal feeding device.The gastrointestinal symptoms,positive rate of stool culture,the ratios of patients with dropping and unplanned replacement of injection syringes,and the bacterial contamination of nasal feeding syringes were compared between the two groups.Results There was a statistically significant difference in incidence of gastrointestinal diarrhea between the two groups(P<0.05);the ratio of positive patients for stool culture in the observation group showed a significant difference compared with that in the control group(P<0.05);the ratios of patients with dropping and unplanned replacement of injection syringes in the observation group were significantly lower than those in the control group(P<0.05).The positive rates of bacteria detection in the control group after 48 and 72 h using nasal feeding syringe were higher than those of the observation groups(P<0.05 or P<0.01).The operative duration of nasal feeding in the observation groups was shorter than that of the control groups,but it showed no significant between-group difference(P>0.05).Conclusion The new nasal feeding apparatus holder can reduce the breeding of bacteria in the syringes,reduce the incidence of diarrhea and improve the nuring efficiency.
