Sedation Safety Assessment Using IPI Monitoring in Pediatric Hematologic Procedures
An observational study of Sedation and Pediatric, run by Ankara City Hospital Bilkent at 1 site in Turkey (Türkiye).
Trial summary
Pediatric hematologic procedures such as lumbar puncture and bone marrow aspiration often require deep sedation due to pain and the need for immobility. Sedative and opioid combinations increase the risk of respiratory depression. Read more about this study

About this study
Official title: Evaluation of Sedation Safety Using Integrated Pulmonary Index (IPI) Monitoring During Pediatric Hematologic Procedures Performed Under BIS Monitoring
Pediatric hematologic procedures such as lumbar puncture and bone marrow aspiration often require deep sedation due to pain and the need for immobility. Sedative and opioid combinations increase the risk of respiratory depression. Integrated Pulmonary Index (IPI) combines SpO₂, EtCO₂, respiratory rate, and heart rate into a single score and may allow earlier detection of respiratory compromise. This study aims to evaluate the safety and effectiveness of IPI monitoring in pediatric patients undergoing hematologic procedures under sedation with BIS monitoring.

What is being measured
The primary outcome is the main question the study is designed to answer.
Incidence of Respiratory Adverse Events (Hypoxia and Apnea)
Evaluation of respiratory safety using standard monitoring versus Integrated Pulmonary Index (IPI). Apnea is defined as cessation of CO2 exhalation for 15 seconds. Hypoxia is defined as SpO2 ≤ 92% or an IPI score drop to ≤ 6. Interventions required (e.g., jaw thrust, oxygen increase) will be recorded.
Measured: Measured pre-procedure (baseline), and at 0, 1, 3, 5, 10, 15, 20, 25, and 30 minutes after initiation of the procedure.
Incidence of Respiratory Adverse Events (Apnea/Hypoxia)
Apnea is defined as cessation of CO2 exhalation for 15 seconds. Hypoxia is defined as SpO2 ≤ 92% or IPI ≤ 6
Measured: Measured pre-procedure (baseline), and at 0, 1, 3, 5, 10, 15, 20, 25, and 30 minutes after initiation of the procedure.
Secondary outcomes (5)
Time to Recovery
Time required for the patient to reach a Modified Aldrete Score of ≥8 (assessing respiration, O2 saturation, consciousness, circulation, and activity) ready for discharge from the recovery room.
Measured: Immediately after the procedure until achievement of a Modified Aldrete Score >=8
Depth of Anesthesia
Assessment of anesthetic depth using Bispectral Index (BIS) monitoring to maintain adequate hypnosis during the procedure.
Measured: Measured pre-procedure (baseline), and at 0, 1, 3, 5, 10, 15, 20, 25, and 30 minutes after initiation of the procedure.
Anesthetic Drug Consumption
Total cumulative dose of Propofol (mg/kg) Total cumulative dose of Fentanyl (mcg/kg)
Measured: During the procedure, up to 30 minutes after initiation of the procedure
Hemodynamic and Respiratory Parameters
Intraoperative monitoring included:
Systolic Blood Pressure (SBP) Diastolic Blood Pressure (DBP) Mean Arterial Pressure (MAP) Heart Rate (HR) Peripheral Oxygen Saturation (SpO₂) Respiratory Rate (RR) End-tidal Carbon Dioxide (EtCO₂)
Measured: Measured pre-procedure (baseline), and at 0, 1, 3, 5, 10, 15, 20, 25, and 30 minutes after initiation of the procedure.
Adverse Events
Postoperative Nausea and Vomiting (PONV) Agitation Bronchospasm Laryngospasm
Measured: Periprocedurally, from induction of sedation until transfer to the hospital ward

Where can I read the original study information?
On the ClinicalTrials.gov record for NCT07733544, which also lists 1 linked publication.
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 29 Jul 2026; AzTrials last refreshed its copy on 8 Nov 2026.
