Evaluation of Halothane and Sevoflurane Effects With Two Different Anaesthesia Induction Methods in Children [Çocukların Anestezi İndüksiyonunda Farklı İki Yöntem İle Uygulanan Halotan ve Sevofluranın Etkilerinin Değerlendirilmesi]

In this study, we compared the induction characteristics of halothane and sevoflurane with two different anaesthesia induction methods on eighty children (1-6 years old) ASA I-II class scheduled for elective surgery. None of the patients were premedicated. Patients were randomly assigned to four equal groups. Anaesthesia induction was achieved as follows: in 50 % O2/N2O, in Group I, starting with halothane 0.5 % concentration, increasing 0.5 % and reaching to 3.5 % maximum; in Group II, starting with sevoflurane 1 % concentration, increasing 1-1.5 % and reaching to 7 % maximum; in Group III, starting with 3.5 % and Group IV, starting with 7 % concentration. The duration of induction, it's completion, intubation and the complications which developed during induction were determined. Measurements of systolic arterial pressure, diastolic arterial pressure and heart rate were recorded before induction, after induction, after intubation, 3 and 5 minutes after intubation. The induction duration was determined shorter in Group III than Group I and in Group VI titan Group II (p<0.05). As there were significant differences for the duration of the induction between Group I and Group II while Group III and Group IV were similar (p?0.05). We didn't see a statistically difference between the groups regarding the completion of the induction, the duration of the intubation, and complications (p>0.05). As a result, sevoflurane was found to be a good alternative to halothane in paediatric patients and the induction with high concentration could be preferred because of the reliable and significantly faster induction.
