To evaluate the feasibility and safety of patient controlled analgesia (PCA) technology during double balloon endoscopy(DBE) inspection.


According to the anesthesia, 120 patients with suspected intestinal disease were randomized into non-anaesthesia(Group A), propofol infusion with TCI vein pump(Group B), and remifentanil vein infusion with PCA pump(Group C), with 40 patients in each group. The feasibility and safety of the three methods in double balloon endoscopy(DBE) inspection were evaluated.


The tolerance in groups B and C was good and the procedure success rate was 100%, significantly higher than Group A(80%, 12/40, P<0.01). The fluctuation of blood pressure, heart rate, and oxygen saturation was significantly greater in groups A and B, while patients in Group C remained stable. The detection rate was 67.5%(27/40) in Group B and 72.5%(29/40) in Group C, significantly higher than that in Group A(37.5%, 15/40, all P<0.01). The depth of endoscope was longer and the length of hospital stay shorter in Group C as compared to Group B(both P<0.05).


The application of PCA technology in the double-balloon endoscopy inspection can meet the individualized analgesic needs of patients in different period, increase the tolerance and compliance of patients to the inspection, facilitate patient-operator communication and positions change, reduce the operation risk, and increase the success rate of double balloon endoscopy.
