- The significance (p value) for various anesthetic paramaters on oculocardiac reflex utilizing the brain wave monitors BIS (top seven rows) and Narcotrend (bottom seven rows.) First three columns represent separate analyses for percent oculocardiac reflex with the first extraocular muscle (EOM; 98% inferior rectus), the second EOM and the third EOM in strabismus surgery cases. Next column ∆OCR represents the difference between %OCR1 and %OCR2 correlated with the difference in brain wave monitors (∆BIS and ∆Narcotrend). Next two colums added for comparison with other authors who employ ordinally defined oculocardiac reflex OCR10% and OCR20% as proportion with 10% bradycardia or 20% bradycardia. Final three columns determine impact of anesthetic variables on the readings from the BIS and Narcotrend monitors for first EOM, second EOM and third EOM observations. Far right and left columns highlight covariates nitrous oxide concentration (N2O), induction propofol, premedication oral midazolam, induction fentanyl, endtidal sevoflurane concentration (sevo), end-tidal carbon dioxide (CO2) and brain wave monitor reading. Below each column in the number of patients in that cohort
