Outcome Measures

Primary Outcomes (4)

  • Mean ANI Changes After Intubation

    ANI stands for Analgesia Nociception Index. Its a dimension less number computed by a pain monitor ranging from 0-100. An index of 100 means absent pain, and the number decreases as pain increases. ANI was measured pre- and post- Intubation

    Before vs after intubation

  • Mean ANI Changes 3 Min After Ketamine Bolus

    ANI was measured pre- and post- i.v. ketamine administration

    Before vs 3 min after Ketamine adminstration

  • Mean ANI Changes 5 Min After Ketamine Bolus

    ANI was measured pre- and post- i.v. ketamine administration

    Before vs 5 min after Ketamine adminstration

  • Mean ANI Changes After Skin Incision

    ANI was measured pre- and post- skin incision

    Before vs after skin incision

Secondary Outcomes (9)

  • Mean BIS Changes After Intubation

    Before vs after intubation

  • Mean BIS Changes 3 Min After Ketamine Bolus

    Before vs 3 min after Ketamine adminstration

  • Mean BIS Changes After Skin Incision

    Before vs after skin incision

  • Mean Heart Rate Change After Intubation

    Before vs after intubation

  • Mean Heart Rate Change 3 Min After Ketamine Bolus

    Before vs 3 min after Ketamine adminstration

  • +4 more secondary outcomes

Other Outcomes (1)

  • Average Ketamine Used

    Surgery
