Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Intraoperative opioid consumption [ Time Frame: During the supratentorial craniotomy surgery ]
    The overall intravenous fentanyl consumption (microgram/ kilogram) during the surgery. The decision to administer fentanyl is guided by the changes of blood pressure and/ or heart rate greater than 20% from baseline level.


Secondary Outcome Measures :
  1. systolic blood pressure change [ Time Frame: within 5 minutes after skull pin insertion ]

    The maximal systolic blood pressure within the first 5 minutes after skull pin insertion will be recorded.

    The systolic blood pressure change from baseline will be calculated. The unit is mmHg.


  2. Heart rate change [ Time Frame: within 5 minutes after skull pin insertion ]

    The maximal heart rate within the first 5 minutes after skull pin insertion will be recorded.

    The heart rate change from baseline level will be calculated. The unit is beats per minute.



Other Outcome Measures:
  1. extubation [ Time Frame: end of surgery, before transferring to the intensive care unit ]
    The rate of immediate extubation before transferring to the intensive care unit (ICU) compared between patients who received 0.5% plain Marcaine and 0.9% normal saline solution.
