To study which variables are able to influence women’s experience of pain during diagnostic hysteroscopy.
Multivariate analysis (phase II) after a randomized, controlled trial (phase I).
Endoscopic gynecologic center.
In phase I, 392 patients were analyzed. Group A: 197 women with carbon dioxide (CO2); group B: 195 women with normal saline. In phase II, 392 patients were assigned to two different groups according to their pain experience as measured by a visual analogue scale (VAS): group VAS >3 (170 patients); group VAS ≤3 (222 patients).
Free-anesthesia diagnostic hysteroscopy performed using CO2 or normal saline as distension media.
Main Outcome Measure(s):
Procedure time, VAS score, image quality, and side effects during and after diagnostic hysteroscopy.
In phase I the median pain score in group A was 2, whereas in group B it was 3. In phase II the duration of the procedure, nulliparity, and the use of normal saline were significantly correlated with VAS >3. A higher presence of cervical synechiae was observed in the group VAS >3. The multivariate analysis revealed an inverse correlation between parity and a VAS >3, whereas the use of normal saline, the presence of synechiae in the cervical canal, and the duration of the hysteroscopy were all directly correlated to a VAS score >3.
Pain in hysteroscopy is significantly related to the presence of cervical synechiae, to the duration of the procedure, and to the use of normal saline; conversely, parity seems to have a protective role.
