[The use of laryngeal mask airway in esophagogastroduodenoscopy in children].

BACKGROUND
The use of laryngeal mask airway (LMA) for inducing and maintaining sedation during EGDS has never been reported in the literature but for a brief letter written by Gajraj in 1996. This study proposes the use of sevoflurane administered through LMA.


METHODS
At the Pediatric Clinic of the University of Rome "La Sapienza" 80 children un-derwent EGDS. After premedication, immediate 8% sevoflurane and 60/40% N2O/O2 induction was delivered. Concentration of sevoflurane was reduced to 1% for maintaining general anesthesia. Heart rate (HR), systemic blood pressure (SBP), respiratory rate (RR), EtCO2 and SpO2 were not invasively monitored. Time for induction, time for emergence as well as complications, if any, were also evaluated.


RESULTS
The monitored parameters did not show any significant changes. The time for loss of eyelash reflex and the time for end of induction were of 121+/-15 sec. 3.5+/-1.3 min respectively. The time for emergence was 3.4+/-1.8 min. Only minor complications were reported.


CONCLUSIONS
The results obtained show that the use of LMA associated to sevoflurane as single inhaling agent can be a valid technique for EGDS in pediatric patients.
