    The effect of dehydrobenzperidol on nausea and vomiting in patient controlled analgesia [Hasta kontrollu analjezide dehydrobenzperidol postoperatif bulanti ve kusmaya etkisi]
    (2000) Ongun B.; Agrali S.; Sakarya M.; Gokpinar B.; Ugur G.
    This study aims to reveal the efficacy of droperidol, a neuroleptic drug with anti-emetic properties, in preventing postoperative nausea and vomiting (PONV) due to IV morphine administered during patient controlled analgesia (PCA). Thirty patients of ASA I-II to whom abdominal hysterectomy was applied were randomly allocated into two groups to receive PCA by morphine alone (Group I) or in combination with dehydrobenzperidol (DHBP) (Group II). Group I received a loading dose of 5 mg IV morphine followed by 1 mg IV boluses with a 10 min lockout period while Group II received morphine plus dehydrobenzperidol (0.05 mg/mL) infusion following loading dose. Otherwise the protocol were the same. Pain and sedation scores, mean and cumulative morphine requirements, incidence of side effects, and vital functions were recorded hourly for 24 hours. Morphine requirement did not show difference between groups. Initial and first hour VAS value was higher in Group I. PONV incidence was significantly lower in Group II (p<0.05), 6.7% vs. 28.6%. None of the patients showed side effects such as respiratory depression, significant haemodynamic changes, and extrapyramidal effects. It is concluded that the addition of DHBP to morphine in intravenous PCA lowered the incidence of PONV safely.

    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.

    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.

    Propofol or midazolam infusion for sedation following myocardial revascularization [Miyokard revaskularizasyonu sonrasi propofol ve midazolam ile sedasyon]
    (1999) Sakarya M.; Askar F.; Derbent A.; Ongun B.; Sungurtekin H.
    In cardiac surgery, postoperative sedation is important not only to facilitate mechanical ventilation but also to avoid post-operative hypertension. This study compared the sedative properties of propofol and midazolam following myocardial revascularization. Fourty patients, NYHA classes 2 or 3, scheduled for coronary artery bypass surgery were included in the study. All patients received the same premedication, anaesthesia induction and maintenance. A nitroglycerin infusion 0.5 (g/kg/min was started after cardiopulmonary bypass (CPB) in all patients and continued throughout the study period. At the end of the surgery artificial ventilation was continued and the patient transferred to the ICU. Patients were randomly allocated to one of two groups after recovery from anaesthesia and received either propofol infusion within the range 0.5-2.0mg/kg/h after a loading dose of propofol (1 mg/kg) or midazolam infusion within the range 0.01-0.05 mg/kg/h after a loading dose of midazolam (0.05 mg/kg). Sedative infusion rates were adjusted to maintain a Ramsay Score of between 3 and 4. Sedative infusion was stopped, if systolic blood pressure (SBP) was <110 mmHg. Additional boluses were given if sedation score was less than 3 on the Ramsay Scale. Morphine was given with bolus doses (10 mg) for pain relief. Central venous pressure (CVP) and pulmonary artery wedge pressure (PAWP) were kept in normal range. Weaning from the ventilator was achieved using standard criteria. Sedation time, the bolus doses of propofol/midazolam, morphine and hemodynamic data (SBP, DBP, HR, CVP, PCWP) were noted for each patient as was the duration of sedation. At the end of the sedation period recovery times, extubation were recorded. Twenty patients were included in each sedation group and there were no significant differences between the two groups with regard to age, weight, gender, operation time, CPB time and peroperative opiate doses. The mean time from stopping sedation to extubation 51.2±32.6 min for propofol versus 106.5±65.6 min for midazolam. Patients in propofol group required less sedative and morphine sulfate bolus doses. Throughout the duration of the study, all patients were hemodynamically stable except for a moderate but clinically acceptable decrease in SBP, DBP, HR in the propofol group. Results of this study have shown that both propofol and midazolam provide adequate sedation following cardiac surgery. However, propofol sedation resulted in faster weaning from the ventilator.
