带气囊肛管的滴液式灌肠器应用于肝性脑病保留灌肠效果研究

目的评价自行设计的带气囊肛管的滴液式灌肠器应用于肝性脑病保留灌肠的临床效果。方法自行设计带气囊肛管的滴液式灌肠器，将60例需行保留灌肠的II—III级肝性脑病患者按简单数字随机法分为两组，实验组30例采用带气囊肛管的滴液式灌肠器保留灌肠；对照组使用传统的开放式袋状灌肠器保留灌肠，观察并比较两组在灌肠过程中药液外溢情况、灌肠液在肠腔内保留时间、患者的耐受性、舒适度及每次灌肠前后静脉血氨浓度。结果两组在灌肠过程中药液外溢发生率、灌肠液在肠腔内保留时间、患者的耐受性、舒适度及静脉血氨浓度均存在明显差异，差异有显著性意义（P〈0．01）。结论应用带气囊肛管的滴液式灌肠器保留灌肠可延长药物在肠腔内的保留时间，明显减少灌肠过程中药液外溢，有效提高治疗效果，减轻患者的痛苦，提高患者的舒适度。

Study on the effect of anal canal gasbag dripped enemator in the patients with hepatic encephalopathy

Objective To evaluate the applied effect of anal canal gasbag dripped enemator. Methods The anal canal gasbag dripped enemator was made by atoxic silica material. 60 patients with II -III grade hepatic encephalopathy needed retention enema were divided into two groups randomly, enema with anal canal gasbag dripped enemator used in the observed group, enema with traditional open baggy used in the control group. Remaining time of physic liquor , blood ammonia before and ＇after enema, the condition of physic liquor flowed outward and satisfactory rate of patients were compared between two groups. Results There was significant difference in remaining time of physic liquor, blood ammonia after enema , the incidence rate of physic liquor flowed outward and satisfactory rate of patients between observed and control group （ P 〈 0. 01 ） . Conclusions The advantages of enema with anal canal gasbag dripped enemator could prolonged remaining time of physic liquor, decrease the incidence rate of physic liquor flowed outward , increase therapy effect and lessen the suffering of patients.
