Abstract

63 pts affected by CIN of various degrees were randomly divided into 3 groups in order to evaluate the pain experienced during laser vaporization of the lesion. All pts were premenopausal and ages ranged between 19 and 39 years. 21 pts received Naproxene Sodium (550 mg) 30 minutes before surgery; 21 pts received placebo and 21 pts received no drug. Laser vaporization was performed with a Coherent System 451 CO2 laser with a power setting of 28 W/cm2 and a spot size of 1.8 mm. The severity of pain was assessed by means of a Visual Analogue Scale. The mean VAS value was 19 for the group treated with Naproxene Sodium; the mean VAS value was 20 for the placebo group and 23 for the group which received no pre-operative drug. Analysis of data from the 3 groups showed no statistically significant difference. Analgesia or anaesthesia before laser surgery for CIN is not a necessity.
