Abstract:
Objective To compare the onset time, duration and adverse effects of stellate ganglion block (SGB) with different concentrations of lidocaine. Methods Two hundred and forty ASA Ⅰ or Ⅱ patients (97 male, 143 female) aged 37-76 yr weighing 48-79 kg were randomly divided into 3 groups ( n = 80 each): group A, B and C received unilateral SGB with 8 ml of 0.6%, 0.8% and 1.0% lidocaine respectively. Unilateral SGB was performed by the same anesthesiologist in all patients. Successful SGB was verified by Homer's syndrome. The onset time, duration and adverse effects were recorded. Results Homer's syndrome was observed in all patients. There was no significant difference in onset time among the 3 groups. The duration of action was significantly longer in group B and C than in group A and in group C than in group B. There was no significant difference in the adverse effects including recurrent laryngeal nerve block, brachial plexus block, local anesthetic intoxication and transient loss of consciousness among the 3 groups. Conclusion SGB can be induced with either 0.6%, 0.8% or 1.0% lidocaine with comparable effectiveness. We suggest using lower concentration of lidocaine.
