I work in a pediatric same day surgery center in OH. We do inhalation induction N2O/ O2 70%/ 30% and after a minute start Sevo 2% and double % every 4-5 breaths. When heart rate starts to slow cut off N2O back off sevo and start IV.Then depending on airway of choice for surgery IV meds administered and LMA or ETT secured.About only time we dont start IV are mask ventilation cases such as BMT's and frenulectomies. Has anyone ever experiencedpatient ceasing spontaneous respirations when eyeball is prepped with betadine? We've been doing rectus recessions and other eye muscle cases with LMA's, regaining spontaneous rspirations quickly after insertion, and when eye prep is done spontaneous respers stop for a brief period requiring assits. Any clues why this should occur?
