Bu çalışmada, 20 adet Süksinilkolin grubu, 20 adet de pankuronyum grubu için olmak üzere toplam 40 adet sokak kedisi kullanıldı. Süksinilkolin 1,5 ve l mg/kg'lık dozlarda, pankuronyum ise 0,2 ve 0,1 mg/kg'lık dozlarda kullanıldı. Bu ilaçların etki başlama ve etki süreleri ile uygulama öncesi, 15. dakikası ve sonrası kalp atım sayıları, vücut ışılan, oksijen saturasyonu, $pCO_2 ve HCO_3$ değerlerine bakıldı. Her iki grupta da oksijen saturasyon değerlerinde hafif artış gözlendi(p

In this study, 20 cats for Succinylcholine group, 20 cats for Pancuronium group totally 40 dogs were used. Succinylcholine was used at the dose of 1.5 and 1 mg/kg; Pancuronium was used at the dose of 0.2 and 0.1 mg/kg. Heart rate, body temperature, oxygen saturation, $pCO_2 and HCO_3$ of the dogs were assessed at the onset time effect and duration of drugs, before treatment, at the 15 min. and after using TOFF GUARD device. In both group, a slight increase on oxygen saturation were recorded (p<0.05). $HCO_ 3$ body temperature and $pCO_2$ values decreased slightly. In the Succinylcholine group; heart rate slightly increased (p<0.05) when high dose was used. In the Pancuronium group heart rate unchanged when either low or high dose were used. In conclusion, when short time intubation is needed Succinylcholine could be used but when long time myorelaxation is needed, Pancuronium could be used safely.
