The effect of pre‐incisional infiltration with lignocaine on postoperative pain after molar teeth extraction under general anaesthesia

Summary In a double‐blind, placebo‐controlled investigation, we studied the effects of pre‐operative inferior alveolar nerve blockade and local anaesthetic intra‐oral infiltration upon postoperative pain following third molar teeth extraction under general anaesthesia. Thirty six patients (12 male),...

Description
Summary:Summary In a double‐blind, placebo‐controlled investigation, we studied the effects of pre‐operative inferior alveolar nerve blockade and local anaesthetic intra‐oral infiltration upon postoperative pain following third molar teeth extraction under general anaesthesia. Thirty six patients (12 male), mean (range) age 25.7 (18–40) years received an injection of 2% lignocaine 2 ml with 1:200 000 adrenaline around the inferior alveolar nerve and tissues adjacent to the third molar tooth on one side and of normal saline 2 ml in a similar fashion to the other side. We measured the pain on each side of the mandible on the 1st, 4th and 11th days after surgery using a visual analogue scale. The visual analogue pain score on the lignocaine and saline sides were 25/100 and 26/100 on day 1, 23/100 and 22/100 on day 4 and 0/100 and 1/100 on day 11. This study has a power of 80% to detect differences at the 5% level of significance of 11/100 on days 1 and 4 and 7/100 on day 11. We found no significant difference in the visual analogue scores between the lignocaine side and the saline side at any stage after the procedure.
