Öğe The analgesic role of ketamine in TIVA with propofol [PROPOFOL ILE YAPILAN TOTAL INTRAVENOZ ANESTEZIDE ANALJEZIK OLARAK KETAMIN'IN YERI](1997) Oztekin S.; Erhan E.; Mert S.; Certug A.This study was planned to compare the differences between the effects of propofol-ketamine and propofol-fentanyl total intravenous anaesthesia on hemodynamic parameters and recovery from anesthesia. Two groups were obtained from 20 patients (ASA class I-II) and the 1st. group received I.V. 10 µg/kg atropin, I.V. 2.5 mg/kg propofol, 2 µg/kg fentanyl for induction while I.V. 1 mg/kg ketamine replaced fentanyl in the 2nd group. During maintenance of anesthesia propofol was infused at a rate of 8 mg/kg/hr during first 10 min., 6 mg/kg/hr during second 10 min. and 4 mg/kg/hr thereafter. In addition 2 µg/kg/hr fentanyl was infused in the 1st. group and 2 mg/kg/hr ketamine in the second group. Systolic and diastolic blood pressures, heart rate and quality of recovery were compared between groups. There were statistically significant decreases in systolic blood pressure, diastolic blood pressure and heart rate in the first group (p<0.05). A more stable hemodynamic status was observed in the second group. Whereas time to recovery was longer in the second group (p<0.05). In conclusion, we recommend the propofol ketamine combination for TIVA due to stable hemodynamic status provided during the surgical procedures.Öğe Comparison of propofol and thiopentone during induction in pediatric anaesthesia [COCUKLARDA ANESTEZI INDUKSIYONUNDA PROPOFOL VE TIYOPENTON'UN KARSILASTIRILMASI](1995) Oztekin S.; Ulusoy B.; Akdeniz A.; Ugur G.In this study, induction characteristics of propofol (4 mg/kg) were compared with thiopentone (5 mg/kg) in 30 children aged between 5-12 years. Unvoluntary movements were observed in 2 children (% 13) who received propofol in contrast to 1 child (6 %) with thiopentone, although those movements were transient and minor. In the propofol group, the mean duration of apnea was longer than the thiopentone group, which was statistically significant (p<0.05). The arterial blood pressure decreases were more profound in propofol group in comparison with thiopentone group. In conclusion, propofol appears to be a promising alternative to thiopentone in children.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 The efficacy of ilioinguinal/iliohypogastric nerve block with bupivacaine in children undergoing inguinal hernia repair [INGUINAL HERNI ONARIMI UYGULANAN COCUKLARDA BUPIVAKAIN ILE YAPILAN ILIOINGUINAL/ILIOHIPOGASTRIK SINIR BLOGUNUN ETKINLIGI](1997) Oztekin S.; Ongun B.; Cokmez B.; Erhan E.; Yegul I.Postoperative pain is a main postoperative problem in pediatric ambulatory cases. Postoperative pain causes longer recovery as well as longer hospitalization which is traumatic to children. In this double-blind prospective study we examined the efficacy of ilioinguinal/iliohypogastric nerve block with bupivacaine or postoperative pain control for inguinal hernia repair. With the allowance of Ethics Committee and parents, 40 ASA I-II children whose range of age was 6-8 years had undergone inguinal hernia repair. They were divided equally into control and nerve block performed groups. In the second group ilioinguinal/iliohypogastric nerve block was performed with 0.25 % bupivacaine in dosage of 0.5 mg/kg at the end of the operation. Patients were evaluated one hour after the surgery, according to standard pain scala, Mann Whitney test was used to evaluate the results statistically. There was no difference in age, weight, duration of anaesthesia and operation between groups. Pain score was found lower in children to whom ilioinguinal/iliohypogastric nerve block was performed with respect to control group, but this was statistically insignificant. In some reports, it has been suggested that ilioinguinal/iliohypogastric nerve block provides an effective postoperative analgesia, in inguinal hernia repair. But in controversy some authors have claimed that there is no statistically significant difference between IG/IH nerve block and other techniques such as skin infiltration anaesthesia for postoperative pain relief in inguinal hernia repair. In our study, pain score decreased in nerve block performed group (similarly) as in other studies, but it was not statistically significant (p>0.05). Because of this reason, in routine application, according to our ideas, it is not always sufficient in all the cases.Öğe Postoperative pain relief for circumcision in children: Penile block and/or usage of rectal diclofenac sodium [COCUKLARDA SIRKUMSIZYONDA POSTOPERATIF AGRININ GIDERILMESI: PENIL BLOK VE/VEYA REKTAL SODYUM DIKLOFENAK UYGULANIMI](1996) Oztekin S.; Erhan E.; Cokmez B.; Ongun B.; Yegul I.In this study, we examined the efficacy penile block performed just after induction and usage of rectal diclofenac sodium after circumcision for perioperative analgesia requirement. 40 children (over 4 years, ASA I and II) scheduled for circumcision were randomly divided into 4 groups. Standard general anesthesia, rectal diclofenac sodium (2.5 mg/kg), penile block (1 cc bupivacaine %0.5 for every 3 years), both penile block and rectal diclofenac sodium were performed in the 1, 2, 3, 4, groups, respectively. Postoperative pain score was evaluated at first hour. Pain score were statistically significant among the groups, but the pain score of group 4 was less then group 3, although the difference was not statistically significant. We concluded that penile block alone and particularly with rectal diclofenac sodium is effective for pain relief in children undergoing circumcision.Öğe Propofol for induction of anaesthesia in children(1992) Oztekin S.; Ulusoy B.; Akyaalti B.; Ugur G.; Tutan A.[No abstract available]
