About

This study evaluate the effects of scalp block versus local infiltration on haemodynamic response to head pin replacement and skin incision and postoperative analgesia in posterior fossa surgery

Full description

In this study 15 patients will receive scalp block with bupivacaine, 15 patients will receive local infiltration with bupivacaine and 15 patients will receive placebo before surgery. The haemodynamic response to head pin replacement and skin incision will be recorded. Postoperatively all patients will have a patient controlled analgesia (PCA) device containing morphine (1 mg/ml) for analgesia. Visual analogue scale (VAS) for pain evaluation, sedation scores, and also postoperative morphine consumption will be evaluated and recorded.

45 participants in 3 patient groups, including a placebo group

scalp block
Active Comparator group
Description:
In this arm, after general anesthesia, before surgery and head pin placement, scalp block will be applied. Scalp block will be performed with bupivacaine (Marcaine 5 mg/mL, 0,5% bupivacaine); nervus supraorbitalis, nervus supratrochlearis, n. auriculotemporalis, nervus zygomaticotemporalis, nervus occipitalis majoris and minoris will be bilaterally blocked with 2-3 ml bupivacaine.
Treatment:
Drug: morphine patient controlled analgesia
Drug: Bupivacaine
local infiltration
Active Comparator group
Description:
In this arm, after general anesthesia, before surgery, 20 ml 0,5% bupivacaine (Marcaine 5 mg/ml, 0,5% bupivacaine) will be infiltrated to head pin points and skin incision area.
Treatment:
Drug: morphine patient controlled analgesia
Drug: Bupivacaine
control
Placebo Comparator group
Description:
In this arm, neither scalp block, nor local infiltration will be performed.
Treatment:
Drug: morphine patient controlled analgesia
