Official Title: The Effects of Scalp Block on Haemodynamic Response and Postoperative Pain in

Brief Summary: 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

Detailed Summary: 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.

Current Primary Outcome:

  • Heart rate response to head pin replacement and skin incision [ Time Frame: Intraoperative ]
    heart rates (beats per minute) will be recorded before induction, before block, before head pinning, head pinning, head pin 5. and 10. minutes, skin incision
  • Systolic arterial pressure response to head pin replacement and skin incision [ Time Frame: Intraoperative ]
    Systolic arterial pressures (mmHg) will be recorded in before induction, before block, before head pinning, head pinning, head pin 5. and 10. minutes, skin incision
  • Diastolic arterial pressure response to head pin replacement and skin incision [ Time Frame: Intraoperative ]
    Diastolic arterial pressures (mmHg) will be recorded before induction, before block, before head pinning, head pinning, head pin 5. and 10. minutes, skin incision
  • mean arterial pressure response to head pin replacement and skin incision [ Time Frame: Intraoperative ]
    Mean arterial pressures (mmHg) will be recorded in will be recorded before induction, before block, before head pinning, head pinning, head pin 5. and 10. minutes, skin incision


Original Primary Outcome: Same as current

Current Secondary Outcome:

  • postoperative pain [ Time Frame: 30. minute, 1.,2.,6.,12.,24. hours pain scores (visual analogue score=VAS) ]
    pain scores (visual analogue score=VAS) will be evaluated.
  • morphine consumption [ Time Frame: 30. minute, 1.,2.,6.,12.,24. hours ]
    morphine dosage used (mg) will be recorded in this time periods


Original Secondary Outcome: Same as current
