Outcome Measures

Primary Outcomes (3)

  • Changes in the SCA prior to and during a nociceptive event during the intraoperative period.

    The pre stimulation values for SCA will be estimated by taking the peak(maximum) value -30 to 0 seconds before the occurrence of the nociceptive event. Post stimulation values for SCA will be estimated by taking the peak (maximum) value +0 to +30 seconds after the nociceptive event. The SCA monitor records skin conductance in peaks per second. Varying from 0.00 peaks per second to 0,40 or more peaks per second. These peaks per second correlate with the pain index according to the manufacturer. With 0.00-0.06 peaks per second equalling pain index of zero and 0,40 or more peaks per second equalling a pain index of ten during surgical stimuli.

    Through study completion, an average of 1 year

  • Changes in the NOL index prior to and during a nociceptive event during the intraoperative period.

    The pre stimulation values for NOL will be estimated by taking the peak(maximum) value -30 to 0 seconds before the occurrence of the nociceptive event. Post stimulation values for NOL will be estimated by taking the peak (maximum) value +0 to +30 seconds after the nociceptive event. The NOL index ranges from 0 to 100. With 0 indicating absence of nociception and 100 indicating severe nociception. The NOL index values are registered at a 5 second interval.

    Through study completion, an average of 1 year

  • Correlation between changes in SCA and changes in NOL index during nociceptive events in the intraoperative period.

    The pre stimulation values for SCA and NOL will be estimated by taking the peak(maximum) value -30 to 0 seconds before the occurrence of the nociceptive event. Post stimulation values for NOL and SCA will be estimated by taking the peak (maximum) value +0 to +30 seconds after the nociceptive event. To compare the diagnostic performance of the SCA and the NOL index we will display data of the SCA and NOL index response to nociception stimuli in a scatterplot and we will perform an intraclass correlation coefficient calculation in order to assess if the response of the patients to the monitors correlate with each other. The NOL index ranges from 0 to 100. With 0 indicating absence of nociception and 100 indicating severe nociception.

    Through study completion, an average of 1 year

Secondary Outcomes (12)

  • SCA response to opioid administration.

    Through study completion, an average of 1 year.

  • NOL response to opioid administration.

    Through study completion, an average of 1 year.

  • SCA response to vasoactive medication administration.

    Through study completion, an average of 1 year.

  • NOL response to vasoactive medication administration.

    Through study completion, an average of 1 year.

  • Correlation between changes in the SCA compared to other predictors of nociception.

    Through study completion, an average of 1 year.

  • +7 more secondary outcomes

Study Population

A total of 50 patients. 25 patients aged 1-4 years old, and 25 patients aged 5-12 years old that are scheduled to undergo elective surgery under general anaesthesia. Patients will be enrolled after obtaining written informed consent. We decided to evaluate the SCA and NOL index in two age groups because of the significant differences of maturations of the bodies across different ages that might influence the measurements made by the SCA and NOL monitor. Furthermore the maturation of the brain of a paediatric patient also differs significantly across different ages. Leading to significant differences in EEG patterns and corresponding BIS monitor values across age groups 1-4 and groups 5-11. Therefore, assessing the NOL and SCA in these two difference age groups results in a better ability to assess the homogeneity of the population as we will also be able to quantify and compare the depth of anesthesia through BIS monitor in these two age groups.

You may qualify if:

  • Male or female
  • ASA I, ASA II and ASA III
  • Aged 1 to 12 years old
  • Scheduled to undergo elective surgery with general anaesthesia
  • Written informed consent obtained from subject or/and subject's legal representatives.

You may not qualify if:

  • Known allergy to the adhesive tape used in the sensors.
  • No free available limb to attach the probes to.
