The Effects of Scalp Block on Haemodynamic Response and Postoperative Pain in Posterior Fossa Surgery
August 18, 2017 updated by: Eren Fatma Akcil, Istanbul University
The Effects of Scalp Block on Haemodynamic Response and Postoperative Pain in
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

Completed
Conditions
Intervention / Treatment
Detailed 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.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Active Comparator: scalp block
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.
|
In the scalp block and local infiltration arms; bupivacaine %0,5 will be used.
Other Names:
End of the surgery all of the patients in 3 groups will receive morphine patient controlled analgesia (PCA) including 1mg/ml morphine.
The PCA was set to administer a bolus dose of 1 mg on demand with a lockout period of 10 minutes and maximum 25 mg for 4 hours.
Other Names:
|
Active Comparator: local infiltration
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.
|
In the scalp block and local infiltration arms; bupivacaine %0,5 will be used.
Other Names:
End of the surgery all of the patients in 3 groups will receive morphine patient controlled analgesia (PCA) including 1mg/ml morphine.
The PCA was set to administer a bolus dose of 1 mg on demand with a lockout period of 10 minutes and maximum 25 mg for 4 hours.
Other Names:
|
Placebo Comparator: control
In this arm, neither scalp block, nor local infiltration will be performed.
|
End of the surgery all of the patients in 3 groups will receive morphine patient controlled analgesia (PCA) including 1mg/ml morphine.
The PCA was set to administer a bolus dose of 1 mg on demand with a lockout period of 10 minutes and maximum 25 mg for 4 hours.
