Öğe Effect of nitrous oxide on cardiac dysrhythmias during anaesthesia(1994) Hamamcioglu G.; Askar F.Z.; Certug A.; Kultursay H.; Kayaalti B.In this study the authors aimed to investigate the effect of nitrous oxide (N2O) on cardiac rhythm during general anaesthesia. Thirty-two cases were included in this study and were randomized into 3 groups. In all groups thiopenthone sodium and vecuronium bromide were used as induction agents. First group (n=11) received 50% O2 + 50% N2O, second group (n=11) 30% O2 + 70% N2O and control group (n-10) 100% O2 during induction. Isoflurane was added in order to achieve adequate levels of anaesthesia in all groups. Systolic, diastolic and mean arterial pressures, pulse rate, twelve leads EGG and cardiac rhythm in lead II were recorded at five different periods. In control group only sinus rhythm was observed. In the first group, one patient showed sinus + atrioventricular junctional rhythm (AVJR) and in the second group one patient showed sinus + bigeminal ventricular premature beat + aberrant conduction of QRS while one patient showed AVJR. No statistically significant difference was found between groups as far as frequency of rhythm disturbance formation was concerned. The authors concluded that, although there was no statistically significant difference between above mentioned groups, it was considered that N2O could increase tendency for AVJR.Öğe The effects of propofol -N2O anaesthesia on upper cortical brain functions(1993) Gokpinar A.B.; Oztekin S.; Firat V.; Hamamcioglu G.; Tutan A.[No abstract available]
