A comparison of the actual and expected pain response following insertion of an intrauterine contraceptive device.
The expected, immediate, and three-minute pain response following IUCD insertion was evaluated in 84 nulliparous women undergoing a first IUCD insertion. Expected pain was significantly higher than immediate pain and both were significantly higher than three-minute pain. Immediate pain following IUCD insertion was positively related to expected pain but the relationship was not strong enough to be of clinical value. The pain was significantly related to the degree of cervical resistance and this relationship was made much more obvious by the use of the expected pain parameter which is a valuable additional clinical measurement in pain research. IUCD insertion pain consists of a short cervical (less than 3 minutes) and longer fundal component. Avoiding excessive uterine manipulation during device insertion results in lower immediate and later pain response scores for a given device when comparisons are made with other studies, where standard techniques were used.
