Ayda Başgül, G.Ulufer Sivrikaya, Birsen Ekşioğlu, Ayşe Hancı

Objective:The effects of propofol infusion or administration of sevoflurane inhalation on arterial blood gases(ABG) during laryngeal mask airway(LMA) ion in short duration procedures were compared.

Material-Methods:After the approval of ethic committee,30 ASA 1-11 patients scheduled for urological surgery were randomly stratified into two groups.Fentanil( 1.5mcg/kg,IV) was administered to the both groups.LMA was ed after suppression of hipopharingeal reflexes with propofol(3mg/kg) in group 1, 30% 02, 70% N20 and sevoflurane(2-6%) inhalational anesthesia in group 2.Arterial blood gases (ABG) samples were taken before induction and thereafter at J5thmin.Statistical analysis was performed with student‘s t test and ANOVA.

Results:Demographic data were similar.There was no significant difference in pH, paC02, EtC02, sa02, HC03, BE values either within groups or between the values at 1st and 15th min.There was a significant difference between the values at the 1st and 15th min within the groups considering pa02 however there was no significant difference between groups.

Conclusions: Administration of propofol infusion or sevoflurane inhalational anesthesia didn‘t cause any significant difference in ABG.The significant difference between 1st and 15th min pa02 values may be strongly related to the increment offi02 from 19% to 30%.LMA is a safe alternative to trakeal intubation independent of applied anesthetic agent.

Keywords: Laryngeal mask,arterial blood gases.
