|
| E.1.1.1 | Medical condition in easily understood language |
| Xenon anesthesia in children undergoing cardiac catheterization |
|
| E.1.1.2 | Therapeutic area | Analytical, Diagnostic and Therapeutic Techniques and Equipment [E] - Anesthesia and Analgesia [E03] |
| MedDRA Classification |
| E.1.3 | Condition being studied is a rare disease | No |
| E.2 Objective of the trial |
| E.2.1 | Main objective of the trial |
| As a primary study aim we hypothesize that the administration of 50% Xenon as an adjuvant to general anesthesia with sevoflurane is safe and feasible |
|
| E.2.2 | Secondary objectives of the trial |
| evaluation of haemodynamic parameters and the analysis of postoperative neurocognitive function. |
|
| E.2.3 | Trial contains a sub-study | No |
| E.3 | Principal inclusion criteria |
| Children aged 4-12 years scheduled for elective diagnostic or interventional cardiac catheterization under general anaesthesia |
|
| E.4 | Principal exclusion criteria |
• Cyanotic congenital heart defects possibly requiring a FiO2 of >40% during the procedure
• High-risk and complex interventional procedures (as defined by the pediatric cardiologist)
• Psychomotoric retardation (defined as the non-achievement of age-specific developmental milestones)
• Lack of informed consent
|
|
| E.5 End points |
| E.5.1 | Primary end point(s) |
Feasibility and safety criteria of xenon anaesthesia in children.
Safety will be assessed by the incidence of intraoperative adverse events:
• Heart Rate: > 20% change from baseline
• Blood pressure: > 20% change from baseline
• Requirements of vasopressors, inotropes and chronotropes.
Feasibility will be tested by intraoperative monitoring of depth of anaesthesia (BIS) and by the intraoperative respiratory profile (as continuously measured by pulse oximetry and capnography).
|
|
| E.5.1.1 | Timepoint(s) of evaluation of this end point |
| safety parameters will be evaluated every 60 sec. from induction to awakening |
|
| E.5.2 | Secondary end point(s) |
- Invasive haemodynamic data, including intra-cardiac, systemic and pulmonary vascular pressures that are routinely measured during these procedures by the interventional cardiologist, after induction of anaesthesia and at the end of the procedure.
-Intraoperative fluid balance.
- Intraoperative xenon consumption.
- Recovery times (measured from the stop of study treatment inhalation): time to open eyes, time to follow commands, time to extubation, time to Aldrete score ≥ 9.
- Incidence of emergence delirium as assessed with the “Paediatric Anaesthesia Emergence Delirium Scale” and the “Four-point Agitation Scale”
- Post-operative nausea (PON) as assessed by a visual analogue score in the post-anaesthesia care unit (PACU) and 12-24h postoperatively.
- Post-operative vomiting (POV) as assessed by a visual analogue score in the post-anaesthesia care unit (PACU) and 12-24h postoperatively.
- Any other complication occurring in the early postoperative period.
- Duration of postanaesthesia care unit and hospital stay.
- Neuro-cognitive testing, 1-2h and 12-24h postoperatively.
- Longitudinal follow-up of cognitive function after 1 year.
Incidence of (serious) adverse events (S)AE at any time point.
