The Clinical Application Of Scalp Nerve Block Combined With Intravenous General Anaesthesia In Neurosurgical Anesthesia

Objective To investigate the clinical application of scalp nerve block combined with intravenous general anaesthesia in neurosurgical anesthesia.Methods40adult patients undergoing frontotemporal craniotomies were randomly divided into two groups:ropivacaine scalp nerve block group (group R) and control group (group C).The patients in group R received scalp nerve block with0.5%ropivacaine before induction while those in group C didn’t. We used propofol and remifentanil in target-controlled infusion and atracurium in constant infusion to maintain anesthesia. The heart rate (HR)、 mean arterial pressure (MAP)、 bispectral index(BIS) of different time、usage of propofol and remifentanil、 extubation time、visual analogue scale and complication were recorded.Results Both groups had stable hemodynamics.The usage of remifentanil in group R was less than that of group C(P<0.05). The difference of extubation time、usage of propofol、incidence of complications were no statistically significant(P>0.05). The difference of VAS(2hour and6hour after operation)was statistically significant (P<0.05).The difference of VAS(24hour and48hour after operation)was no statistically significant (P>0.05) Conclusion Scalp nerve block combined with intravenous general anaesthesia is simple with stable hemodynamics、less usage of remifentanil and better analgesic effect.
