Clinical Trial Summary

This study aimed to record diaphragm electrical activity (Edi) during the preextubation (weaning) and postextubation periods and to analyze whether Edi monitoring could predict extubation success.


Description:

This prospective observational study included 25 pediatric patients who were intubated due to respiratory failure in the pediatric intensive care unit of the tertiary university-affiliated Marmara University Hospital between August 2014 and July 2015. To conduct the study, we obtained informed consent from the patient's parents and ethical approval from the Marmara University Faculty of Medicine Scientific Research Ethics Committee Board on 06.09.2014. Pediatric patients included which had indication for the insertion of a nasogastric tube (Edi catheter), independent of the study. So Edi catheter had been used instead of nasogastric tube. When the patients were ready for clinical weaning in accordance with the clinician, the Edi catheter was appropriately inserted into the patients. Then, a spontaneous breathing trial (SBT) was performed and diaphragm activity monitoring was recorded during this process. The patients who met the inclusion criteria switched in a spontaneous breath trial with pressure support ventilation (PSV) or NAVA (Neurally Adjusted Ventilatory Assist) on a Maquet (Solna, Sweden) Servo-i mechanical ventilator for both ventilation modes The patients' demographic and clinical characteristics, mortality scoring, vital parameters (HR, TA, SpO2, RR) and ventilatory parameters (Edi peak, Edi min, FiO2, expiratory Vt), as well as follow-up period were recorded. Arterial/capillary blood gases were taken within the last four hours before extubation and within the first, sixth, 12th, 18th and 24th hours after extubation. If arterial blood gas monitoring was initiated in the patient, arterial monitoring was continued. If capillary blood gas monitoring was initiated, capillary monitoring was continued. Edi data were recorded for at least 24 hours before and after extubation. Edi values were obtained retrospectively from the trend diagram, which provides 24-hour continuous records on the ventilator screen.

Outcome

Type Measure Description Time frame Safety issue
Primary Diaphragm electrical activity (Edi) monitoring Macquet (servo-i) mechanical ventilator measures the electrical activity (Edi) of the diaphragm (microvolts). Edi signals are measured using special feeding tubes (Edi catheter) equipped with tiny sensors at the level of gastroesophageal junction. In the ventilator, Edi trend values can be monitored continuously as 24-hour records. up to 2 days
Primary Mechanical ventilatory monitoring ventilatory parameters (Edi peak, Edi min, FiO2), were recorded during the follow up. up to 2 days
Secondary Arterial/capillary blood gases If arterial blood gas monitoring was initiated in the patient, arterial monitoring was continued. If capillary blood gas monitoring was initiated, capillary monitoring was continued. Arterial/capillary blood gases were taken within the last four hours before extubation and within the first, sixth, 12th, 18th and 24th hours after extubation.
Secondary Vital signs ((fever, heart rate (HR), respiratory rate (RR), tension arterial)) Vital signs recorded by pediatric intensive care nurses. up to 2 days
Secondary Expiratory tidal volume Patients who had >5ml/kg expiratory tidal volume considered to be ready for extubation From spontaneous breathing trial until the time for extubation
