Öğe Effectiveness of intravenous ephedrine infusion during spinal anaesthesia for Caesarean section based on maternal hypotension, neonatal acid-base status and lactate levels(Australian Soc Anaesthetists, 2002) Turkoz, A; Togal, T; Gokdeniz, R; Toprak, HI; Ersoy, OMaternal cardiovascular changes and neonatal acid-base status, including lactate levels, were assessed in 30 healthy women undergoing elective caesarean section under spinal anaesthesia. Patients were allocated randomly to receive IV ephedrine infusion (n = 15) (5 mg.min(-1)) immediately after the spinal injection or bolus administration of IV ephedrine (n = 15) (10 mg) in case of development of hypotension. Maternal and neonatal blood pressure, heart rate and acid-base status including lactate levels were compared between the groups. Systolic blood pressure in the bolus group was significantly lower when compared to the infusion group. Nausea was observed in one patient (6%) in the infusion group and nausea and vomiting were observed in 10 patients (66%) in the bolus group. Although umbilical arterial pH values were significantly lower in the bolus group, lactate levels were similar. In conclusion, ephedrine infusion prevented maternal hypotension, reduced the incidence of nausea and vomiting and led to improved umbilical blood pH during spinal anaesthesia for caesarean section.Öğe Oral clonidine premedication does not reduce postoperative vomiting in children undergoing strabismus surgery(Blackwell Munksgaard, 2003) Gulhas, N; Turkoz, A; Durmus, M; Togal, T; Gedik, E; Ersoy, MOBackground: We evaluated the effect of oral clonidine on postoperative vomiting (POV) in children undergoing strabismus surgery. Methods: Eighty ASA physical status I children aged 3-12 years were randomly assigned to one of two groups in a double-blinded manner. One hour before surgery, each patient in the clonidine group (n=40) received clonidine 4 mug kg(-1) in apple juice 0.2 ml kg(-1) , and each of the controls (n=40) received apple juice 0.2 ml kg(-1) only. The protocol for general anesthesia was propofol-sevoflurane in N-2 O/O-2 . A paracetamol suppository was administered in each case to prevent postoperative pain. Patient responses during 0-48 h after anesthesia were recorded as complete (no POV, no antiemetic rescue required), retching, vomiting, or rescue antiemetic. Results: There were no significant differences between the clonidine and control groups regarding the number of patients with complete response (21 vs. 18, respectively) retching (10 vs. 14, respectively), vomiting (19 vs. 22, respectively), or rescue antiemetic (9 vs. 12, respectively) during the first 48 h. Conclusion: Oral premedication with clonidine 4 mug kg(-1) did not reduce the rate of POV in the children undergoing strabismus surgery.Öğe Remifentanil and acute intermittent porphyria(Lippincott Williams & Wilkins, 2002) Durmus, M; Turkoz, A; Togal, T; Koroglu, A; Toprak, HI; Ersoy, MO[Abstract Not Available]Öğe Secondary cross-clamping and blood cardioplegia for refractory ventricular fibrillation after aortic cross-clamp removal(Texas Heart Inst, 2002) Turkoz, A; Gulcan, O[Abstract Not Available]
