Changes in arterial blood gases during laryngeal mask airway ion with sevoflurane inhalational or propofol infusion anesthesia

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.

Laringeal maske kullanýmýnda sevoflurane inhalasyonu veya propofol infüzyonu esnasýndaki arter kan gazý deðiþiklikleri

Giriþ: Lariýýgeal maske kullanýlan kýsa süreli giriþimlerde propofol infiizyonu veya sevoflurane inhalasyonu kullanýmýnýn arter kan gazý üzerindeki etkileri karþýlaþtýrýldý.
Materyal ve Metod: Etik kurul izniyle,ürolojik giriþim planlanan ASA l-I II, 30 olgu rast gel e iki gruba ayrýldý.Her iki grubada intravenöz(IV) l.5pg!kg fentanil verildi.Grup I‘de IV 3mg/kg propofol,grup 2 de%30 O2 + %70 N20 ve %6-2 sevoflurane inhalasyonýýyla hipofaringeal refleksler baskýlandýktan sonra laringeal maske takýldý. Ýdame 3mg/kg propofol veya %2 sevoflurane ile saðlandý. Indiiksiyondan önce ve 15. dakikada arter kan gazý örneði alýndý, istatistiksel analizde student t testi, ANOVA kullanýldý.
Bulgular: Demografik veriler benzerdi. PH, paC02, EtC02, sa02, HCOj, BE deðerlerine bakýldýðýnda gerek grup içi gerekse 1. ve 15.dakika deðerleri arasýnda anlamlý fark yoktu. Pa02 deðerinde grup içi 1. ve 15. dakika deðerleri arasýnda(p<0.001) fark var ancak gruplar arasý anlamlý fark yoktu.
Sonuçlar: Olgularýmýzda genel anestezi uygulamasýnda propofol infüzyonu veya sevoflurane inhalasyonu seçimi arter kan gazý deðerleri üzerinde anlamlý bir fark yaratmanýýþtýr.Grup içi I. ve 15. dakika pa02 deðerleri arasýndaki anlamlý farklýlýk fi02 deðerlerinin %19‘dan %30‘a çýkarýlmasýna baðlý olmasý kuvvetle muhtemeldir. Laringeal maske hava yolu temininde kullanýlan anesteziðe baðlý olmaksýzýn trakeal entubasyona güvenilir bir alternatiftir.
