A prospective, randomized study was undertaken to objectively compare pain tolerance of 2 methods of local analgesia for outpatient hysteroscopy. Patients in group 1 received a paracervical block using 20 ml of 1% lignocaine. Patients in group 2 received a uterosacral block using 2 ml of 2% lignocaine. There was no statistical difference between the 2 groups (p = < 0.65) in efficacy of pain relief. The method used for patients in group 2 reduces time and costs for outpatient hysteroscopy.
