Full Outline of UnResponsiveness (FOUR) score is a more comprehensive score used to assess eye response, motor response, brainstem reflexes, and respiration that was introduced to overcome the drawbacks of Glasgow coma scale (GCS) score. Our aim was to assess which score best predicts mortality and poor outcome in aneurysmal subarachnoid haemorrhage (aSAH) patients. ⋯ FOUR score is among the most specific and moderately sensitive tool for prediction of mortality. However, WFNS and HH grade are more specific in predicting the 28-day outcome.

Measurement of end-tidal anaesthetic gas concentrations (ETAG) is currently a pragmatic indicator for monitoring anaesthetic depth. We aimed to assess the performance of ETAG for sevoflurane (ETAG-sevo) with bispectral index (BIS) and difference between inspired and end-tidal oxygen concentration (Fi-Et)O2% in measuring anaesthetic depth in toddlers and preschool children. Primary outcome was to correlate BIS with ETAG-sevo. Secondary outcome was to correlate (Fi-Et)O2% with ETAG-sevo and to derive cut-off value of (Fi-Et)O2%which corresponds with light planes of anaesthesia [minimum alveolar concentration (MAC <0.6)]. ⋯ BIS was an unreliable measure of anaesthetic depth. (Fi-Et)O2% values >7 corresponded with light planes of anaesthesia.
