Review Meta Analysis Comparative Study
Pentax Airway Scope(®) vs Macintosh laryngoscope for tracheal intubation in adult patients: a systematic review and meta-analysis.
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.

Although the brain is the target organ of general anaesthesia, the utility of intra-operative brain monitoring remains controversial. Ideally, the incorporation of brain monitoring into routine practice would promote the maintenance of an optimal depth of anaesthesia, with an ultimate goal of avoiding the negative outcomes that have been associated with inadequate or excessive anaesthesia. ⋯ Whether such devices prove to be useful will depend not only on their ability to influence anaesthetic management but also on whether the changes they promote can actually affect clinically important outcomes. This review highlights the evidence for the role of bispectral index monitoring, in particular, in guiding anaesthetic management and influencing clinical outcomes, specifically intra-operative awareness, measures of early recovery, mortality and neurocognitive outcomes.
