Bilateral anesthesia into Spix's spine. Ten years' experience.

AIM: This study examines 10.112 cases in 10 years of bilateral block anaesthesia to Spix's spine. The aim of this study is therefore to eliminate any doubt about executing a bilateral anaesthesia to Spix's spine for the extraction, in inclusion and impacted of the inferior wisdom teeth.

METHODS: A retrospective study was carried out on 10,112 operations (59% females, 41% males,) regarding the removal of the lower 3 molar teeth undertaken in the past 10 years. Locoregional anaesthesia and standard instruments and protocol were applied to all operations. The anaesthetic used was mepicavina at 2% with epinefrine 1:100,000 with a 4 x 25 mm, 27 Gauge needle. In order to completely anaesthetize the areas subject to surgery a quantity of approximately 3-ml on each side was injected. Local anaesthetics used were the same throughout the study; all the patients were in good health and not undergoing any pharmaceutical treatment.

RESULTS: The onset of complications was 3 times less when using local anaesthesia (LA) compared to general anaesthesia (GA). It was also proven that local anaesthesia was advantageous, as the operation time was considerably less (24 min for LA and 46 min for GA).

CONCLUSIONS: The paper shows that LA offers a significant reduction in complications, psychological advantages for the patients and facilitation of the operational position too, so that GA is to be preferred only for non-cooperative patients.
