About this study
This prospective single-center randomized controlled trial aims at evaluating the safety and feasibility of an hemoadsorption protocol using Jafron HA-60 during cardio-pulmonary bypass in 20 pediatric patients undergoing open-heart surgery.
Read the detailed description
Cardiopulmonary bypass (CPB) is an extracorporeal system that temporarily takes over the functions of the heart and lungs by diverting blood during cardiac surgery. However, the use of CPB is know to trigger a significant systemic inflammatory response, largely mediated by cytokines. In severe cases, this response may result in vasoplegia, hypotension, and subsequent organ dysfunction. Several pharmacological interventions have been investigated to reduce the incidence and severity of this post-surgical inflammatory response, but results have been very mitagated. Among emerging strategies, the pre-procedural removal of circulating cytokines through hemoadsorption represents a promising approach. In particular the use of a HA-60® cartridge (Jafron Biomedical, Guangdong, China) integrated into the CPB circuit may help attenuate the inflammatory cascade.
This pilot study is designed to evaluate the feasibility and safety of implementing an hemoadsorption protocol during cardiopulmonary bypass in a pediatric population. Pediatric patients scheduled for complex cardiac procedures will be enrolled before surgery and randomly assigned in a 1:1 ratio to either receive hemoadsorption therapy with standard care (intervention group) or standard care alone (control group).
In the intervention group, an HA-60® hemoadsorption cartridge will be integrated into the CPB circuit during setup and used throughout the duration of the bypass. Four blood samples will be collected : Post-anestesia induction, CPB termination, ICU admission, and 24 hours post ICU admission-to measure cytokine levels. Clinical data, including vital signs, organ support, demographics, and medical history, will be recorded in the electronic medical records.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
HemoadsorptionDevice
The hemoadsorption treatment will be performed during the entire duration of the CPB. The blood flow within the hemoadsorber will be controlled and set to 7% of the theoretical minimal CPB flow which is calculated as 2.5 L/min/1.73m2 of body surface area.
| Study group | Role | What they receive |
|---|---|---|
| Hemoadsorption | Experimental | Cardiopulmonary bypass (CPB) will be conducted as per institutional protocols and an HA-60® cartridge (Jafron Biomedical, Guangdong, China) will be inserted within the circuit for hemoadsorption. Receives: Device: Hemoadsorption |
| Control | No intervention | Cardiopulmonary bypass will be conducted as per institutional protocols, without hemoadsorption (standard-of-care) |
What is being measured
The primary outcome is the main question the study is designed to answer.
Screened-to-enrolled patients' ratio and number of intervention delivery group
- Screened-to-enrolled patients' ratio ≥ 0.3*
- ≥ 80% of intervention delivery in intervention group (number of patients who received hemoadsorption > 50% of CPB duration)
- Duration of recruitment: no more than 36 months (approximately 0.56 patient per month)
- <5% of study interruptions attribuable to insufficiant resources or logistical constraints *(Previous pilot studies in intervention contexts report screened-to-enrolled patient ratios of approximately 0.30-0.50; therefore a threshold of ≥ 0.30 has been chosen as a minimal acceptable benchmark for feasibility.)
Measured: Start CPB, End CPB, 1 Day and aftrer 28 day
Device-related adverse events
Assessed with the occurrence of 4 categories of adverse events in each group:
Device-related complications:
- Technical failure to perform the treatment: thrombosis of the cartridge, circuit leak or inability to perform the treatment for all CPB duration.
Tolerance:
- New allergic or anaphylactoid reaction (stage ≥ 2 by H. L. Mueller [5])
- New fever (> 39°C for more than an hour).
Bleeding/haematological complications*:
- Intracranial haemorrhages
- Need for massive transfusion (>10mL/kg/h during more than 3 consecutive hours)
- Incidence of new thrombocytopenia (mild <150 G/L, moderate, <100 G/L severe < 50 G/L) *(We will consider separately bleeding/haematological complications occurring during the procedure (from CPB initiation to ICU admission) and those occurring from ICU admission to day 7 or ICU discharge, whichever occurs first.)
All other event judged relevant by the investigator (i.e. cardiac arrest). NB: "New" means not present at the time of CPB initiation
Measured: From beginning of cardiopulmonary bypass to 7 days after ICU admission or ICU discharge wichever occurs first.
Secondary outcomes (11)
Pediatric Logistic Organ Dysfunction-2 (PELOD-2) score at 24 hours
Difference in the PELOD-2 score between before surgery and 24 hours after admission to intensive care. The PELOD-2 score ranges from a minimum of 0 (indicating no organ dysfunction) to a maximum of 33 (indicating the most severe level of organ dysfunction)
Measured: Measured between post-anestesia induction and 24 hours post ICU-admission
Pediatric Logistic Organ Dysfunction-2 (PELOD-2) worst value
Efficacy measured by the PELOD-2 worst value between admission to intensive care and 24 hours after admission to intensive care. The PELOD-2 score ranges from a minimum of 0 (indicating no organ dysfunction) to a maximum of 33 (indicating the most severe level of organ dysfunction)
Measured: Within 4 hours of ICU admission
Pediatric Logistic Organ Dysfunction-2 (PELOD-2) score at 48 hours
PELOD-2 difference between groups in the PELOD-2 score measured between 24 hours and 48 hours after ICU admission.

Measured: Measured between 24 hours and 48 hours after ICU admission

The record lists 1 site in Switzerland. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?

How can a doctor refer a patient or contact the research team?
Contact Isabelle Cristiani (+41 79 556 84 60, isabelle.cristiani@chuv.ch), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Screened-to-enrolled patients' ratio and number of intervention delivery group (time frame: Start CPB, End CPB, 1 Day and aftrer 28 day). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 10 Feb 2026.
