title: Ropivacaine compared to lidocaine for tonsillectomy under local anaesthesia.
abstract: The aim of the present study was to investigate the safety and efficacy of ropivacaine compared to lidocaine for tonsillectomy under local anaesthesia. During the last 2 years, 77 patients undergoing tonsillectomy under local anaesthesia in the seated position were randomised to receive ropivacaine or lidocaine. The following parameters were recorded: time to surgical anaesthesia, the duration of the procedure, postoperative pain, the need for analgesics during the first 10 h after surgery, cardiac arrhythmias, the occurrence of allergic reaction and larynx spasm. It took significantly longer to reach surgical anaesthesia in the ropivacaine patients (8.3+/-1.3 min versus 2.7+/-0.8 min.), but the pain immediately following the procedure was significantly lower (1.0+/-0.4 versus 2.6+/-1.0). Adjuvant analgetics were administered later and in significantly lower doses in the ropivacaine patients. There were no adverse reactions. In conclusion, ropivacaine in local tonsillectomy is safe, has a longer onset-time, but is more efficient concerning postoperative pain than lidocaine.
