Summary

This prospective randomized controlled trial aims to compare the effectiveness of High-Flow Nasal Cannula (HFNC) versus Tight Face Mask (TFM) in maintaining oxygenation during rapid sequence induction (RSI) for endotracheal intubation in adult patients. Participants will be randomly assigned in a 1:1 ratio to receive either HFNC or TFM for preoxygenation before induction of anesthesia. The primary outcome is the lowest peripheral oxygen saturation (SpO₂) recorded from induction until successful endotracheal intubation. Secondary outcomes include the incidence of oxygen desaturation (\<90%), duration of apnea, duration of laryngoscopy, intubation time, number of intubation attempts, and peri-intubation complications. The study will determine whether HFNC provides superior oxygenation compared with conventional face mask preoxygenation during RSI and may contribute to improving airway management protocols and patient safety.

Conditions

  • Hypoxemia
  • Airway Management
  • Endotracheal Intubation
  • Rapid Sequence Induction

Interventions

DEVICE

High-Flow Nasal Cannula

Participants assigned to this intervention will receive preoxygenation using a heated, humidified high-flow nasal cannula delivering oxygen at a flow rate of 60 L/min with an inspired oxygen fraction (FiO₂) of 1.0 (100%) for 3 minutes before rapid sequence induction. Oxygen delivery will be continued throughout the apneic period and laryngoscopy until successful endotracheal intubation.

DEVICE

Tight Face Mask

Participants assigned to this intervention will receive standard preoxygenation using a tightly fitting anesthesia face mask delivering 100% oxygen at a flow rate of 15 L/min for 3 minutes before rapid sequence induction. The face mask will be removed immediately before laryngoscopy in accordance with standard clinical practice.
