The effects of sevoflurane and isoflurane on recovery, mental and psychomotor functions in outpatient anaesthesia [Sevofluran ve isofluranin gunubirlik (outpatient) anestezi uygulamalarinda derlenme ile mental ve psikomotor fonksiyonlar uzerine etkileri]

In our study, we aimed to compare the effect of sevoflurane and isoflurane on postoperative recovery time, mental and psychomotor functions and pain relief in fourty adult patients (ASA I-II) undergoing for ambulatory (out-patient) surgery. The patients were divided into two groups, randomly. All patients were premedicated by diazem (10 mg IM) and atropin (0.5 mg IM). Anaesthesia induction was obtained with thiopentone (5 mg/kg) and vecuronium (0.1 mg/kg) administrated in patient who needed endotracheal entubation or muscle relaxation. Anaesthesia was maintained with sevoflurane (1.0-2.5%) and N2O (66%) in oxygen in group I and with isoflurane (0.5-1.5%) and N2O (66%) in oxygen in group II. Systolic arterial pressure (SAP), diastolic arterial pressure (DAP), peripheral O2 saturation (SpO2) and ECG were observed before induction, after induction and intubation, before, after extubation and at postoperative 5., 10., 15., 20., 25., 30. minutes. However, PAR scala was recorded following extubation and postoperative 5., 10., 15., 20., 25., 30., 40., 50., 60., 75. and 90. minutes. SCS (Short Cognitive Scale) and VAS (Visual Analog Scale) were recorded at postoperative 5., 10., 15., 20., 25., 30., 40., 50., 60., 75. and 90. minutes. Eight and up values was accepted reliable for PAR. There were not found statistically significance between groups in SAP, DAP, HR, and SpO2 values (p>0.05). PAR value was statistically significance higher in group I than group II at 10. minutes (p<0.05). There were not found significance at the another times (p>0.05). Eight and up values for PAR were much lower in group I (p<0.05). There were not found statistically significance between groups in SCS and VAS values (p>0.05). Finally sevoflurane has shorter postanaesthetic recovery time than isoflurane. However sevoflurane and isoflurane can be used easily for ambulatory (out-patient) surgery and does not show any difference on recovery regarding mental and psychomotor function
