Abstract
ABSTRACT
The anesthetic properties of paracervical and direct infiltration of lignocaine were compared in a randomized, double-blind, controlled clinical trial. Women were given either 10 ml of 2% lignocaine into the right and left paracervical tissues or 2 ml injected directly into four quadrants of the cervical transformation zone before vaporizing the dysplastic cervical epithelium with a carbon dioxide laser. Operative pain was assessed objectively during the treatment, and subjective pain was assessed postoperatively with a linear analog score. Direct infiltration is associated with lower pain scores (median pain score 14% compared with 30%, p = 0.005). We have now abandoned paracervical blocks in our laser colposcopy clinic and recommend direct injection. (J GYNECOL SURG 12:197, 1996)
