Abstract
The aim of this study was to assess the sedative-analgesic activity of different doses of remifentanil and effects of preoperative anxiety on intraoperative pain levels in patients attending a dental clinic. The patients (n=60) were divided into two groups according to the remifentanil infusion dose given: group R1: 0.05μg/kg/min; group R2: 0.1μg/kg/min. The following were evaluated: haemodynamic parameters, State-Trait Anxiety Inventory (STAI) TX-I score, pain level due to local anaesthesia injection, time to reach a Ramsay Sedation Scale (RSS) score of 3, amount of bolus dose, total drug consumption, recovery period, patient and surgeon satisfaction, and complications. The patient satisfaction score on a visual analogue scale (VAS) was 90 in group R1 and 100 in group R2 (P=0.008); the surgeon satisfaction score was 80 in group R1 and 90 in group R2 (P=0.004). The time to reach an RSS score of 3 and the amount of bolus dose were significantly lower in group R2 than in group R1. High levels of anxiety did not affect intraoperative pain levels. In conclusion, high doses of remifentanil can safely be used for various same-day dental surgery interventions.
