Öğe A comparison of the effects of propofol, etomidate and thiopental used in combination with alfentanil for out-patient anaesthesia(1992) Askar F.Z.; Turkoglu M.; Firat V.; Tutan A.; Ayanoglu O.[No abstract available]Öğe A comparison of the effects of propofol, etomidate and thiopentone used in combination with alfentanil for out-patient anaesthesia(1993) Askar F.Z.; Turkoglu M.; Firat V.; Tutan A.; Ayanoglu O.[No abstract available]Öğe The effect of inhalation anaesthetics on SaO2 during induction in pediatric patients(1994) Oztekin S.; Gokpinar A.B.; Akman H.; Ugur G.; Tutan A.The aim of the study was to compare the influence of airway irritation upon oxygen saturation (SaO2) during halothane and isoflurane anaesthesia in children. Thirty unpremedicated children with ASA grades I and II were allocated randomly to receive either halothane or isoflurane. Heart rate and rhythm were monitored with an ECG and SaO2 was measured continuously with a pulse oximeter. The findings of the present study indicate that induction of anaesthesia with isoflurane may be prolonged and the irritant airway effects may interfere with the tissue oxygenation. In contrast, halothane produces rapid and smooth induction and SaO2 is usually not reduced. In conclusion, if isoflurane is used as an alternative to halothane for the induction of anaesthesia in unpremedicated children, a higher incidence of airway complications with associated decreases in SaO2 may result.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]Öğe Morquio syndrome and anaesthesia (Case report)(1992) Balcioglu S.T.; Aksu H.; Ovul F.; Tutan A.[No abstract available]Öğe Neuromuscular effect of pipecuronium bromide(1994) Ozzeybek D.; Elar Z.; Celebi G.; Tutan A.'Onset of action', 'duration of action', 'recovery index' and 'reversibility with anticholinesterases' of pipecuronium bromide, a new muscle relaxant, were studied on 24 cases with ASA physical status 1 who received thiopental, N2O-O2 and isoflurane anesthesia. Neuromuscular function was monitored with mechanomyography (MMG) and train-of-four (TOF) stimulation model of 3 groups each containing 8 patients; group I was given 70 µg.kg-1; group II 85 µg.kg-1 and group III 100 µg.kg-1 pipecuronium bromide. There was no statistically significant difference between 3 groups on the basis of 'onset of action' which was found to be 2.7 min; 2.8 min, 2.2 min in the groups I, II and III, respectively (p > 0.05). Statistically significant difference between groups on the basis of 'duration of action' which was found to be 73.3 min in the group I, 77.1 min in the group II and 104.8 min in the group III, was recognized to be due to the significantly longer action of the agent on 100 µg.kg-1 dose group (p < 0.01). 'Recovery index' and % T1 values before and 2, 5, 8 and 10 min after decurarization showed no statistically significant difference between groups (p > 0.05). TOF ratios before decurarization which were found to be 10.1% in the group I, 20.3% in the group II and 10.0% in the group III showed statistically significant difference between groups (p < 0.01). According to data obtained from this study, it was concluded that: by using the suggested doses for clinical practice, action of pipecuronium bromide, which started in 2-3 min and lasted 73-105 min, might be easily reversed by anticholinesterases (reversal time being dose dependent) and might be preferred for surgical procedures especially requiring long periods of muscle relaxation.Öğe Propofol for induction of anaesthesia in children(1992) Oztekin S.; Ulusoy B.; Akyaalti B.; Ugur G.; Tutan A.[No abstract available]
