Design and clinical practice of the controllable pressure infusion

Objective To prolong the retention time of drugs in the intestines and to simplify the operation steps.Methods The Controllable Pressure Infusion was made of nonpoisonous polyethylene.60 patients with kidney failure were randomly divided into experimental group and control group, 30 cases in each group.The former received the controllable pressure infusion for enema, while the latter received the injection set for enema.The following index were recorded, such as the time of injection and keep, the patient's subjective feelings ( abdominal butterfly, anus fall to bloated sense ), the condition of physic liquor flowed outward and the rate of independent operation.Results In experimental group, compared with the control group, the time of injection reduced ( P < 0.01 ), the time of keep added ( P < 0.01 ), the patient' s subjective feelings reduced ( P < 0.05 ), the rate of independent operation was raised ( P < 0.001 ).Conclusions The controllable pressure infusion is helpful to prolong the retention time of drugs in the intestines, patient can independently operate.
