Effects of the intermittent injection with super-low pressure on the postoperative pain control during the uterine artery embolization for uterine XXXX .

@entity1868 @entity158
OBJECTIVE: Uterine artery embolization (UAE) has been commonly used for uterine @entity1868 with satisfactory effects, but the @entity158 during and following the procedure with an occurrence rate in 100%. The aim of this study was to observe the effects of intermittent injection with super-low pressure on @entity158 control during the UAE for uterine @entity1868 . METHODS: 67 subjects were divided into 2 groups with 47 in-group A and 20 in group B. A underwent UAE with the intermittent injection at super-low pressure, while B underwent routine UAE. @entity158 was assessed according to WHO analgesic ladder. Meanwhile, all were scored with the visual analogue scale (VAS). RESULTS: The numbers of first, second and third step analgesic user in Group A were 21, 18 and 6, respectively, with 2 non-analgesic users, while in Group B were 4, 6 and 10, respectively without non-analgesic user (chi-square = 7.043, P = 0.008). VAS showed @entity158 control in 23 cases, satisfactory in 18 and poor in 6 in Group A, while in Group B, were 4, 8 and 8, respectively (chi-square = 7.329, P = 0.007). Mean follow-up was 16.5 months (range, 6-32 months). The abnormal menstruation was improved and the ultrasound examination 6 months later demonstrated a significant decrease in the diameter of @entity1868 (from 6.65    2.40 cm to 5.22    1.86 cm, t = 3.186, P = 0.002). CONCLUSION: The application of intermittent injection with super-low pressure during UAE can decrease and possibly eliminate post-operative @entity158 . But the procedure time was increased.
