About

The purpose of this study is to evaluate the safety and performance of High-Frequency Oscillatory Ventilation (HFOV) modes of the Servo-n ventilator in neonates and infants, by using a prospective, observational, single-arm (i.e., non-controlled) and multi-center Post-Market Follow-up (PMCF) study design. HFOV treatment will be evaluated by assessing ventilation and oxygenation variables, and safety will be evaluated by documentation of device related adverse events.

Full description

The purpose of this study is to evaluate the safety and performance of HFOV modes of the Servo-n ventilator in neonates and infants. This is a prospective, observational, single-arm (i.e., non-controlled) and multi-center PMCF study in neonates and infants between 0.3 to 8 kg. All study procedures are within each hospital's routine clinical practice.The primary endpoints includes variables which are routinely used per clinical practice for assessing the status of patient's ventilation and oxygenation, respectively. Secondary endpoints are used to evaluate safety of Servo-n HFOV during its use by assessing rates of adverse event/ device deficiencies related to the Servo-n HFOV device, and by assessing rates of mortality, Bronchopulmonary Dysplasia (BPD) and Retinopathy at Intensive Care Unit (ICU) discharge. Data collection will take place up to 24 hours prior to HFOV treatment, during HFOV and up to ICU discharge. Additional general data such as ventilator settings, reasons for initiating/terminating HFOV treatment and demographics will also be recorded.

Enrollment: 75 estimated patients

Sex: All

Volunteers: No Healthy Volunteers

Inclusion criteria

• Provision of written informed consent by the patient's legally designated representative(s) (may be obtained as deferred consent up to 24 hours after HFOV initiation: valid for both elective and rescue HFOV patients)

• Patients eligible for HFOV ventilation with Servo-n:

  • Patient is either switched from conventional mechanical ventilation or HFOV with other device to Servo-n HFOV based on clinicians judgement (rescue HFOV). Note: the reason for the switch has to be that the patient failed to oxygenate or ventilate adequately with CMV or the other HFOV device

    ; OR

  • Patient was prior without or with any type of non-invasive respiratory support and is put on invasive HFOV treatment based on clinicians judgement (elective HFOV)

• Patient has not already been on HFOV in a previous episode, unless the etiology of respiratory failure has changed during the same hospitalisation. For example, initial HFOV treatment for RDS, second HFOV episode of NARDS of any etiology (will be enrolled as a new patient case). NOTE1: When a patient failed weaning on conventional ventilation within 6 hours, requiring to be put back on HFOV it will be counted as one HFOV episode (weaning failure) NOTE2: When a patient is temporarily put on conventional ventilation for transport or a surgical intervention, and will be put back to HFOV afterwards, it will be counted as one HFOV episode (HFOV paused).

• Patient has a body weight from 0.3 to 8.0 kg

Exclusion criteria

• Diagnosis of congenital diaphragmatic hernia
• Severe cardiac anomaly expected to need corrective surgery or catheter-based intervention within 30 days from birth
• Cyanotic heart disease
• Intracranial hemorrhage, Grade III or IV
• Congenital malformations with the exception of isolated lung hypoplasia
• Persistent pulmonary hypertension (PPHN) with a documented shunt on the level of the foramen ovale
• Bronchopulmonary Dysplasia (BPD) /Chronic Lung Disease (CLD)

Trial design

75 participants in 1 patient group

Servo-n HFOV treatment

Description:

As this study is single-armed (non-controlled), all patients in this study receive the same treatment, i.e. Servo-n HFOV treatment. There are however two subgroups, elective HFOV and rescue HFOV treatment

Treatment:

Device: Servo-n HFOV modes
