Outcome Measures

Primary Outcomes (7)

  • Pharmacokinetics (PK) of clonidine; S-concentration

    Clonidine analyses will be performed with LC-MS standard assay on a Waters ultra-pressure liquid chromatography (UPLC)-MS/MS system and then statistically analysed with NONMEM (Non-linear Mixed Effect Modelling) populationbased PK statistics

    Repeated blood samples (5 minutes after the loading dose, just before start of the clonidine infusion and at 1 hour, 24 hours, 48 hours and 72 hours after start of the infusion

  • Pharmacokinetics (PK) of clonidine; elimination half-time

    Statistical analyses will be performed with NONMEM (Non-linear Mixed Effect Modelling) populationbased PK statistics

    Data from repeated blood samples (5 minutes after the loading dose, just before start of the clonidine infusion and at 1 hour, 24 hours, 48 hours and 72 hours after start of the infusion

  • Pharmacokinetics (PK) of clonidine; clearance

    Statistical analyses will be performed with NONMEM (Non-linear Mixed Effect Modelling) populationbased PK statistics

    Data from repeated blood samples (5 minutes after the loading dose, just before start of the clonidine infusion and at 1 hour, 24 hours, 48 hours and 72 hours after start of the infusion

  • Pharmacokinetics (PK) of clonidine; volume of distribution

    Statistical analyses will be performed with NONMEM (Non-linear Mixed Effect Modelling) populationbased PK statistics

    Data from repeated blood samples (5 minutes after the loading dose, just before start of the clonidine infusion and at 1 hour, 24 hours, 48 hours and 72 hours after start of the infusion

  • Neurophysiologic amplitude-integrated EEG response in relation to PK

    Analyse of single cortical events and their dynamics, based on burst detection and measuring features of individual bursts as well as their mass statistical behaviour over time.

    From 30 minutes before start of treatment until 72 hours after start of treatment.

  • Neurophysiologic amplitude-integrated EEG response; longer term brain function in relation to PK

    Assessment of longer term brain function using measures of long range correlation and brain activity cycling.

    From 30 minutes before start of treatment until 72 hours after start of treatment.

  • Neurophysiologic amplitude-integrated EEG response; assessment of global brain network function in relation to PK

    Assessment of global brain network function will be based on Activation Synchrony Index.

    From 30 minutes before start of treatment until 72 hours after start of treatment.

Secondary Outcomes (11)

  • Change in/association between heart rate in relation to PK .

    From 30 minutes before start of treatment until 72 hours.

  • Change in/association between blood pressure (systolic, diastolic and mean arterial blood pressure) in relation to PK .

    From 30 minutes before start of treatment until 72 hours.

  • Change in/association between peripheral oxygen saturation in relation to PK .

    From 30 minutes before start of treatment until 72 hours.

  • Change in NIRS (near-infrared spectroscopy) response in relation to PK .

    From 30 minutes before start of treatment until 72 hours.

  • Change in pain, stress and behavioral state as assessed with a pain scale for continuous pain/stress (Astrid Lindgrens and Lund childrens hospitals Pain and stress assessment scale for Preterm and Sick newborn infants, ALPS-Neo) in relation to PK.

    From 30 minutes before start of treatment until 72 hours.

  • +6 more secondary outcomes

Study Arms (1)

Clonidine

Preterm infants (\< gw 37+0) who are in need for analgesic or sedative medication will receive treatment with clonidine according to an algorithm based on pain and sedative scoring results

Drug: Clonidine

Interventions

Clonidine will be administered to preterm infants in need of analgesia and sedation; either as the primary drug for comfort and light sedation or as an "add-on" drug to opioids according to an algorithm based on pain and sedative scoring results. Opioids are mostly given to postoperative patients. These drugs (morphine or fentanyl) will not be studied, but a baseline PK sample will be taken to correlate to the baseline aEEG.

Eligibility Criteria

AgeUp to 37 Weeks
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17)
Sampling MethodProbability Sample
Study Population

Sick preterm infants admitted to the NICU in need for analgesic or sedative medication according to clinical judgment.

You may qualify if:

  • Preterm infants (\< gw 37+0) who are in need for analgesic or sedative medication according to clinical judgment (scoring with pain assessment scales; ALPS-Neo and Comfort-Neo)
  • Existing arterial or venous cannulas/catheters for repeated non-traumatic blood sampling
  • Informed and written parental consent

You may not qualify if:

  • Hemodynamic instability (same as in clinical routine).
  • Cardiac malformations in need for postnatal surgery.
  • Any serious medical condition or ethical issues that could, in the Investigators opinion, interfere with the study procedures.
