Comparison of direct laryngoscopy and video-assisted laryngoscopy in pediatric intensive care unit

Area of Science:

• Pediatric Critical Care Medicine
• Anesthesiology
• Airway Management

Background:

• Direct laryngoscopy (DL) is a standard airway management technique.
• Pediatric intensive care units (PICUs) present unique airway challenges.
• Limited data exists comparing video-assisted laryngoscopy (VAL) and DL in PICU settings.

Purpose of the Study:

• To compare the effectiveness of VAL versus DL for glottic visualization during intubation in a PICU.
• To assess the first-attempt success rate of intubation using VAL compared to DL.
• To evaluate the quality of glottic view achieved with each technique.

Main Methods:

• A comparative study involving pediatric patients (1 month to 18 years) requiring intubation in a PICU.
• Exclusion criteria included limited neck extension, congenital anomalies, and recent airway surgery.
• Data collected included intubation time, glottic visualization scores (POGO), and Cormack and Lehane grades.

Main Results:

• Video-assisted laryngoscopy (VAL) demonstrated significantly higher POGO scores (p<0.001) compared to direct laryngoscopy (DL).
• VAL provided a significantly better glottic view (Cormack and Lehane grade 1) than DL (p<0.001).
• While DL required more intubation attempts, neither group experienced intubation failure.

Conclusions:

• Video-assisted laryngoscopy (VAL) offers superior glottic visualization and potentially higher first-attempt success rates in pediatric intensive care unit intubations.
• VAL may be a more effective tool for managing pediatric airways compared to direct laryngoscopy.
• Further research should explore long-term outcomes and cost-effectiveness.
