Randomized Comparison of the Pentax AirWay Scope and Macintosh Laryngoscope for Tracheal Intubation in Patients With Obstructive Sleep Apnoea

Pentax Airway Scope® vs Macintosh laryngoscope for tracheal intubation in adult patients: a systematic review and meta‐analysis

“…We included 17 comparisons in 16 RCTs (Fig. , Table ), with 1801 participants . The difficulty of intubation was anticipated as normal in eight RCTs and difficult in nine RCTs.…”

“…We analysed the interactions of these outcomes with the anticipated difficulty of intubation. Anticipated difficult airways were: morbidly obese participants ; participants with immobilised cervical spines ; participants with obstructive sleep apnoea ; predicted difficult intubations (thyromental distance < 6 cm, Mallampati classification 3–4 or inter‐incisor distance < 4 cm) ; during chest compression . We estimated risks of bias in the following methodological domains: sequence generation; allocation concealment; blinding of participants, personnel and outcome assessors; incomplete outcome data; selective outcome reporting; and other potential threats to validity .…”
