Öğe Anaesthesia for Caesarean section in the presence of aortic coarctation(Lippincott Williams & Wilkins, 2002) Togal, T; Durmus, M; Koroglu, A; Demirbilek, S; Karaaslan, K; Ersoy, O[Abstract Not Available]Öğe Early detection of the TURF syndrome(Lippincott Williams & Wilkins, 2000) Bakan, N; Gedik, E; Ersoy, O[Abstract Not Available]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 Effects of S(+) ketamine added to bupivacaine for spinal anaesthesia for prostate surgery in elderly patients(Greenwich Medical Media Ltd, 2004) Togal, T; Demirbilek, S; Koroglu, A; Yapici, E; Ersoy, OBackground and objective: Intrathecal ketamine as the sole anaesthetic agent has demonstrated a lack of cardiovascular depression that should be of advantage in an elderly population. S(+) ketamine has three-times the analgesic potency of R(-) ketamine and its antinociceptive effects after intrathecal administration in rats are known. We decided to evaluate the effects of intrathecal S(+) ketamine added to a small dose of spinal bupivacaine in elderly patients undergoing transurethral prostate surgery. Methods: Forty males over 60 yr old, scheduled for transurethral prostate resection under spinal anaesthesia, were studied in a prospective, double-blinded, randomized way. Patients were allocated to receive either bupivacaine 10 mg or bupivacaine 7.5 mg combined with S(+) ketamine 0.1 mg kg(-1). Spinal block onset time, maximum sensory level, duration of blockade, haemodynamic variables, postoperative analgesic requirements and adverse events were recorded. Results: Onset times of motor and sensory block were shorter in the bupivacaine plus S(+) ketamine group. Incomplete motor block of the lower extremities was seen in 80% of the patients in bupivacaine plus S(+) ketamine group. Duration of complete motor block and spinal analgesia was shorter in the bupivacaine plus S(+) ketamine group. There was no significant difference in arterial pressure. Heart rate decreased after spinal anaesthesia in the bupivacaine plus S(+) ketamine group and was significantly lower until the end of anaesthesia. The incidence of adverse effects was not different between groups. Conclusions: Intrathecal S(+) ketamine administered with a low dose of bupivacaine provides shorter motor and sensory block onset time, shorter duration of action and less motor blockade in elderly males.Öğe Postoperative delirium and defibrillation(W B Saunders Co, 1999) Türköz, A; Türköz, R; Gülcan, O; Ersoy, O[Abstract Not Available]
