Abstract:
Objective To compare the efficacy and safety of lidocaine and ropivacaine for scalp block in providing adequate analgesia with minimum side effects during awake craniotomy.Methods60 patients, ASA 1~2, were randomized into either lidocaine (L) group (n=30) or ropivacaine (R) group (n=30). 1% lidocaine or 0.5% ropivacaine were taken for scalp nerve block 15 min before incision. Supplemental oxygen was given using nasal prongs that were adapted for the monitoring of end tidal CO2 and respiratory rate. Serial parameters about circulation and respiratory were measured and drug consumption were recorded.ResultsThe hemodynamic parameters of L group were higher than R group in the latter stage(P<0.05). L group was associated with significantly more consumption of sufentanil and more respiratory depression than R group(P<0.05).ConclusionRopivacaine, taking for scalp block undergoing awake craniotomy, is associated with less consumption of analgesic and less respiratory depression than lidocaine.
