Hypothesis
Does jaw lift cause less laryngeal interference during lightwand-guided intubation compared to combined jaw and tongue traction?
Conclusion
Jaw lift manoeuvre results in less laryngeal interference and epiglottic distortion than combined jaw and tongue traction.
Supporting Evidence
- Epiglottic distortion was observed in 6 patients with jaw lift and 17 patients with combined jaw and tongue traction.
- Laryngeal interference was significantly higher with combined manoeuvre than with jaw lift alone.
- Time to intubate was longer with combined manoeuvre compared to jaw lift.
Takeaway
This study found that lifting the jaw causes fewer problems when putting a tube down someone's throat than using both the jaw and tongue together.
Methodology
A randomised, double-blinded, cross-over study comparing jaw lift and combined jaw and tongue traction in 84 patients undergoing general anaesthesia.
Potential Biases
Observer bias may have influenced the assessment of laryngeal interference.
Limitations
The study did not assess the position of laryngeal cartilages and could not accurately quantify the volume of the orolaryngeal space.
Participant Demographics
Patients aged above 18 years, both genders, ASA Physical Status 1 or 2.
