Diagnostic hysteroscopy using liquid distention medium: comparison of pain with warmed saline solution vs room-temperature saline solution.

AbstractSTUDY OBJECTIVE:
To compare pain intensity and degree of satisfaction reported by patients undergoing hysteroscopic examinations using saline solution kept at room temperature (control group) or saline solution heated to 37.5°C (test group).
DESIGN:
Randomized, controlled, prospective study (Canadian Task Force Classification I).
PATIENTS:
Sixty-four women underwent diagnostic hysteroscopy during the second half of 2008.
INTERVENTION:
In both the test and control groups, examinations were performed using the vaginoscopy technique without use of a speculum or Pozzi tenaculum forceps. Pain was assessed using a visual analog scale immediately after the examination and at 1 and 15 minutes after the procedure.
MEASUREMENTS AND MAIN RESULTS:
Immediately after the examination, mean (SD; 95% confidence interval) pain intensity in the warmed saline solution group was 3.84 (2.71; 2.89-4.79), and in the room-temperature saline solution group was 4.31 (3.02; 3.18-5.44) (p = .51). At 1 and 15 minutes after the procedure, pain intensity in the 2 groups was, respectively, 2.41 (2.00; 1.66-3.16) and 2.43 (2.49; 1.57-3.30) (p = .96), and 1.83 (2.30; 1.02-2.64) and 1.85 (2.06; 1.08-2.62) (p = .96). Differences were not significant. Time to complete the examination was 3.80 (1.32; 3.34-4.26) minutes in the test group, and 3.75 (1.10; 3.34-4.15) minutes in the control group (p = .82). The satisfaction rate with the warmed distention medium was 84% (95% confidence interval, 72%-96%), and with the room-temperature saline solution was 85% (73%-97%) with saline at room temperature (p = .48).
CONCLUSION:
There was no statistically significant difference between the 2 groups insofar as pain, duration of the examination, and degree of patient satisfaction.
