Despite increasing the likelihood of a Cormack-Lehane grade 1 view, pooled results from the studies showed no difference between the Pentax Airway Scope and standard Macintosh laryngoscope for:
• Rate of intubation on first attempt.
• Time for intubation.
• Incidence of oral or pharyngeal injury.

The Pentax Airway Scope improves laryngeal view compared with the standard Macintosh laryngoscope but does not facilitate intubation.

Real-time ultrasound guidance of central line insertion dramatically reduces the incidence of procedural failure (RR 0.18), arterial puncture (RR 0.25), haematoma (RR 0.30), pneumothorax (RR 0.21), and haemothorax (RR 0.10). Studies specifically investigating children and infants were however too small to make significant conclusions.
