Randomized Controlled Trial Comparative Study Clinical TrialBeneficial effect of low-dose peritonsillar injection of lidocaine-adrenaline before tonsillectomy. A placebo-controlled clinical trial.
Most studies investigating the effect of preincisional injection of local anaesthetic with adrenaline in tonsillectomy have used rather large doses and an inter-individual study design. They are inconclusive regarding the effect on post-tonsillectomy pain but have shown that the peroperative blood loss is reduced. However, side effects to high adrenaline doses are common. In the present study, the effect of injecting a small dose of lidocaine-adrenaline was investigated by using an intra-individual study design. ⋯ Low-dose injection of lidocaine-adrenaline before tonsillectomy reduces blood loss and has a small but significant beneficial effect on early postoperative pain. Furthermore our results indicate that operation time is reduced. We therefore recommend subcapsular injection of 3 ml of 1% lidocaine with 1/200.000 adrenaline under each tonsil before tonsillectomy.
