Scalp nerve block with 0.5% Levobupivacaine adds up to intravenous fentanyl for intraoperative pain control during supratentorial craniotomy with brain tumor removal. The scalp block includes 4-6 nerves which give sensory supply to related location with the use of total 10-15 ml of 0.5% Levobupivacaine. Intravenous fentanyl is used for intraoperative analgesia in both groups with continuous infusion (1 mcg/kg/hr until opening of dura and then 0.5 mcg/kg/hr until finishing of dural closure) and increment doses (0.5 mcg/kg) also given. is used for intraoperative analgesia in both groups with continuous infusion (1 mcg/kg/hr until opening of dura and then 0.5 mcg/kg/hr until finishing of dural closure) and increment doses (0.5 mcg/kg) also given.
Scalp nerve block with 10-15 ml of 0.9% sodium chloride(NaCl), or normal saline (NSS) includes 4-6 nerves which give sensory supply to related location (sham block). Intravenous fentanyl is used for intraoperative analgesia in both groups with continuous infusion (1 mcg/kg/hr until opening of dura and then 0.5 mcg/kg/hr until finishing of dural closure) and increment doses (0.5 mcg/kg) also given.
