Abstract

Abstract:

BACKGROUND: YOUMET cervical dilating rod is made of absorbent polymer materials and has non-toxic side effects, which can avoid cross-infection in one-time use.

OBJECTIVE: To observe the clinical effects of YOUMET cervical dilating rod used for cervical orifice dilation before intrauterine device insertion and removal as well as before artificial abortion operations.

METHODS: Totally 275 female subjects schedule for cervical dilation during intrauterine device insertion and removal operations, and suction abortion for pregnancy within 10 weeks were randomly divided into two groups: 137 were included in observation group in which YOUMET cervical dilating rods were applied and 138 were included in control group in which Gongshuning glue sticks were used. Their cervical softening and dilatation situation, analgesic effect, and combined reactions during operation were observed.

RESULTS AND CONCLUSION: Between the two groups, no statistical significance in general biological characteristics was found; Dilating effects in intrauterine device removing operations during child-bearing period and menopause were better in the observation group than the control group (P < 0.05). Rates of pain during insertion were higher in the observation group than the control group (P < 0.05). Rates of pain during indwelling period for both groups were comparatively low, which showed no statistical significance. There was no record related to the application of cervical orifice dilating products in postoperative follow-up visit. Both products were safe with no cervical injury, slow heart rate and drop in blood pressure. YOUMET cervical dilating rod has trustworthy and safe dilating effects, which can remarkably alleviate pain.
