Çocuklarda magnetik rezonans görüntülemede propofol ile ketaminin karşılaştırmalı değerlendirilmesi

Abstract

We didn't find any dens regions or atelectatic areas in lung tomographic studies in group I. However, dens regions in the dependent parts of the lungs were seen in two patients of group II. Systolic, diastolic and mean blood pressure decreased in group I. While heart rate increased, But systolic, diastolic and mean blood pressure and heart rate increased in group II. There was not seen statistically significant difference between groups for breathing frequency, and oxygen saturation. Postanaesthetic recovery score (PAR) was found 8 and up 20 of 22 patients in I group (% 91) whereas only in 14 of 20 patients was 8 and up in II group(% 70). In our study, there was not found difference between groups on haemodynami, oxygenation and not causing atelectasia in pediatric patients who have an indication for radiologic procedure. However, postanesthetic recovery time was found to be shorter in propofol group than ketamine group. tn conclusion, We should prefer ketamine in the patients who have an atalectasia risk due to not causing diffuse lung density. 35SUMMARY In this study, we aimed to compare the effects of ketamine and propofol on recovery, oxygenation, haemodynami and formation of atelectasis in radiologic procedure. The protocol was approved by parental consent and ethic committe of Çukurova University. To study, fourtytwo patients who have no lung pathology, in ASA class I or II were accepted. Patients who have indication for radiologic procedure were divided in to two groups. While propofol was used in I. group(n=22), ketamin was used in II. group(n=20). Blood pressure, heart rate, breathing frequency, oxygen saturation and computerised lung tomography in supine position were obtained in all patients before anaesthesia induction. Propofol was administred 100 microgram/kg/min by continuous infusion following 2- 2.5 mg/kg induction doses in group I. Ketamine was applied 0.5-1 mg/kg intermittant bolus in each 10-15 min following 2 mg/kg induction doses in group II. Blood pressure, heart rate, breathing frequency, oxygen saturation was remeasured in 5., 10., 15., 20., 25., 30. minutes after anaesthesia maintenance during computed lung tomography in supine position. Computerised lung tomography was repeated in 60. and 90. minutes during anaesthesia. The patients breathed in air. All the patients were observed for two hours at the end of anaesthesia. Post anaesthetic recovery score (PAS) of patients was determined during this period. There was not found demographic statistically significance between groups(P>0.05). Using computerised tomography, dens regions in the left lung lingular segment was seen in one awake patient. In this patient, ketamine was used for induction and maintenance of anaesthesia. Dens regions did not chance in 60 and 90 minutes following anaesthesia There was not seen statistically significant difference between groups for radiologic procedure and time of anaesthesia. 34We didn't find any dens regions or atelectatic areas in lung tomographic studies in group I. However, dens regions in the dependent parts of the lungs were seen in two patients of group II. Systolic, diastolic and mean blood pressure decreased in group I. While heart rate increased, But systolic, diastolic and mean blood pressure and heart rate increased in group II. There was not seen statistically significant difference between groups for breathing frequency, and oxygen saturation.
