Intrauterine Anesthesia in Operative, Awake, Office Hysteroscopy. A Randomized Double-blind Placebo-controlled Trial

The study group underwent hysteroscopy using saline to which 10ml of 2% lidocaine was added to the first 1000 ml. This dose of lidocaine was calculated to allow maximal benefits with minimal potential complications. The maximal dose of lidocaine is 5mg\\kg in adults which translates to 200mg in a 40kg patient. We have set 200 mg as the maximal dose of lidocaine in our study, assuring the dosage is safe. The rest of the procedure following the first 1000ml of saline was completed using saline alone as needed.

The control group underwent hysteroscopy using a saline distension medium.
