Outcome Measures

Primary Outcomes (1)

  • Change in blood pressure

    Blood pressure was recorded by the blinded anesthesiologist

    Baseline in time frame before pin insertion (T1-T4) , time during pin insertion (T5), repeated measurement time every 1 minute until 5 minutes after pin applications (T6-T10).

Secondary Outcomes (3)

  • Change in mean arterial pressure

    Baseline in time frame before pin insertion (T1-T4), time during pin insertion (T5), repeated measurement time every 1 minute until 5 minutes after pin applications (T6-T10).

  • Change in heart rate

    Baseline in time frame before pin insertion (T1-T4), time during pin insertion (T5), repeated measurement time every 1 minute until 5 minutes after pin applications (T6-T10).

  • adverse events

    Baseline in time frame before pin insertion (T1-T4), time during pin insertion (T5), repeated measurement time every 1 minute until 5 minutes after pin applications (T6-T10).

Study Arms (2)

Dexmedetomidine (Group A)

EXPERIMENTAL

In induction period, group A received dexmedetomidine 1 µg/kg diluted to 20 ml with 0.9% normal saline 10 minute through a syringe pump. Three minutes before application of skull pins, group A received infusion of 2 ml of 0.9% normal saline.

Drug: DexmedetomidineDrug: 0.9% normal salineDevice: Skull pins

Fentanyl (group B)

ACTIVE COMPARATOR

In induction period, group B received 20ml of 0.9% normal saline.Three minutes before application of skull pins, group B received infusion of fentanyl 1 µg/kg diluted to 2 ml with 0.9% normal saline

Drug: FentanylDrug: 0.9% normal salineDevice: Skull pins

Interventions

Dexmedetomidine 1 µg/kg diluted to 20 ml with 0.9% normal saline was administration. If adverse events were occurred, the patient will receive rescue drugs.

Also known as: precedex
Dexmedetomidine (Group A)

Fentanyl 1 µg/kg diluted to 2 ml with 0.9% normal saline was administration. If adverse events were occurred, the patient will receive rescue drugs.

Fentanyl (group B)

0.9% normal saline was use to dilute the study drugs

Masking Details
After written informed consents were obtained, all participant was blinded from the study drug. The study drugs (dexmedetomidine and fentanyl) were prepared by anesthetist nurse who not involved in the study. Dexmedetomidine was labeled with group A whereas fentanyl was labeled with group B. The study drug was administrated by the blinded anesthiologist. Blood pressure, mean arterial pressure, and heart rate were recorded by same blinded anesthesiologist

Intervention Model
PARALLEL
Model Details: A randomized, double-blinded controlled trial was conducted from September 2015 to September 2016 in Srinagarind Hospital, Faculty of Medicine, Khon Kaen University, Thailand. Sixty patients who underwent craniotomy with insertion of skull pin were randomly allocated into group A and B. After patients entered the operative room, blood pressure and heart rate were measured (T1) then repeated measurement again (T2) when started induction, intubation and infusion dexmedetomidine 1 µg/kg over 10 min infusion in group A whereas group B received normal saline. At 3 minutes before skull pin insertion (T3), patient in group B received a single bolus of fentanyl 1 µg/kg whereas group A received normal saline. Then hemodynamic responses were recorded and repeated again at one minute before skull pin insertion (T4). Blood pressure and heart rate were observed at the time of skull pin insertion (T5) then repeated every 1 minutes after skull pin application until 5 minutes (T6 - T10).
