Study summary

The goal of our study is to compare classical Rapid Sequence Induction (RSI) and modified Rapid Sequence Induction (mRSI) in pediatric patients with a full stomach undergoing urgent surgical procedures. Due to reduced oxygen reserve in children, modified RSI incorporating gentle positive pressure ventilation has been proposed to reduce hypoxemia while maintaining protection against aspiration.

Read the detailed description

This randomized clinical trial compares classical Rapid Sequence Induction (RSI) and modified Rapid Sequence Induction (mRSI) in pediatric patients with a full stomach undergoing urgent surgery. After standardized preoxygenation with 100% FiO₂ for two minutes, patients are randomized to one of two groups. In the classical RSI group, patients receive propofol (3-5 mg/kg) until loss of consciousness followed by succinylcholine (1-2 mg/kg, age-adjusted), and tracheal intubation is performed 30 seconds after induction without positive pressure ventilation. In the modified RSI group, patients receive fentanyl (4 µg/kg) prior to propofol and succinylcholine at the same doses, followed by gentle positive pressure ventilation using the anesthesia machine in inspiratory support mode (inspiratory pressure 10 cmH₂O, PEEP 5 cmH₂O) for 30 seconds before tracheal intubation. Demographic characteristics, type of surgery, heart rate, systolic and mean arterial pressure, oxygen saturation, and peri-intubation complications including aspiration and desaturation (defined as SpO₂ \< 90%) are recorded and compared between groups to evaluate safety and efficacy of the two induction techniques

Study arms

  • Active comparator
    Classical Rapid Sequence Induction group

    Patients received propofol (3-5 mg/kg) followed by age-adjusted succinylcholine (1-2 mg/kg), and tracheal intubation was performed 30 seconds later without positive pressure ventilation.

    Other: Classical Rapid Sequence Induction

  • Experimental
    Modified Rapid Sequence Induction (mRSI) group

    Patients received fentanyl (4 µg/kg) followed by propofol and succinylcholine at the same doses as the RSI group, then underwent 30 seconds of gentle positive pressure ventilation (inspiratory pressure 10 cmH₂O, PEEP 5 cmH₂O) before tracheal intubation.

    Other: Modified Rapid Sequence Induction

Interventions

  • OtherClassical Rapid Sequence Induction

    Patients received propofol (3-5 mg/kg) until loss of consciousness, followed by succinylcholine (1-2 mg/kg, adjusted for age). Tracheal intubation was performed 30 seconds after the completion of induction, without any positive pressure ventilation

  • OtherModified Rapid Sequence Induction

    Patients received fentanyl (4 µg/kg), followed by propofol and succinylcholine at the same doses as in the RSI group. Following induction, patients received gentle positive pressure ventilation using the anesthesia machine in inspiratory support mode (inspiratory pressure: 10 cmH₂O; PEEP: 5 cmH₂O) for 30 seconds before tracheal intubation

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Feb 23, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
