    Anesthesia Management in a Child with Osteogenesis Imperfecta and Epidural Hemorrhage
    (Elsevier Science Inc, 2013) Erdogan, Mehmet Ali; Sanli, Mukadder; Ersoy, Mehmet Ozcan
    Osteogenesis Imperfecta (OI) results from gene mutation that causes defective or insufficient collagen formation. It may cause various anesthetic complications due to the difficulty in airway management, existence of spinal deformity, respiratory disorders, cardiac anomalies, thrombocyte function disorder, risk of hyperthermia, bacillary invagination, bone deformities and metabolic disorders. The anesthesia management of OI patients should be exercised with caution given certain risks of respiratory disorders. These risks are due to thorax deformity, bone fractures during moving or changing position, mandibular and cervical fractures related with intubation, difficult intubation and malignant hyperthermia. The anesthetic technique using Total Intravenous Anesthesia (TIVA) and laryngeal mask airway is suitable for pediatric patient care with OI. However, these techniques have not yet been reported as useful in neurosurgery case reports. In this study, we present the use of TIVA and ProSeal Laringeal Mask in a child with OI and epidural hemorrhage. We came to the conclusion that LMA and TIVA can safely be used in the anesthetic management of OI patients with severe anesthetic problems. (C) 2013 Sociedade Brasileira de Anestesiologia.

    (Baskent Univ, 2015) Gedik, Ender; Toprak, Huseyin Ilksen; Koca, Erdinc; Sahin, Taylan; Ozgul, Ulku; Ersoy, Mehmet Ozcan
    Objectives: The goal of this study was to compare the effects of 2 different regimens on blood glucose levels of living-donor liver transplant. Materials and Methods: The study participants were randomly allocated to the dextrose in water plus insulin infusion group (group 1, n = 60) or the dextrose in water infusion group (group 2, n = 60) using a sealed envelope technique. Blood glucose levels were measured 3 times during each phase. When the blood glucose level of a patient exceeded the target level, extra insulin was administered via a different intravenous route. The following patient and procedural characteristics were recorded: age, sex, height, weight, body mass index, end-stage liver disease, Model for End-Stage Liver Disease score, total anesthesia time, total surgical time, and number of patients who received an extra bolus of insulin. The following laboratory data were measured pre- and postoperatively: hemoglobin, hematocrit, platelet count, prothrombin time, international normalized ratio, potassium, creatinine, total bilirubin, and albumin. Results: No hypoglycemia was noted. The recipients exhibited statistically significant differences in blood glucose levels during the dissection and neohepatic phases. Blood glucose levels at every time point were significantly different compared with the first dissection time point in group 1. Excluding the first and second anhepatic time points, blood glucose levels were significantly different as compared with the first dissection time point in group 2 (P < .05). Conclusions: We concluded that dextrose with water infusion alone may be more effective and result in safer blood glucose levels as compared with dextrose with water plus insulin infusion for living-donor liver transplant recipients. Exogenous continuous insulin administration may induce hyperglycemic attacks, especially during the neohepatic phase of living-donor liver transplant surgery. Further prospective studies that include homogeneous patient subgroups and diabetic recipients are needed to support the use of dextrose plus water infusion without insulin.

    Effects of Propofol or Etomidate on QT Interval During Electroconvulsive Therapy
    (Lippincott Williams & Wilkins, 2009) Erdil, Feray; Demirbilek, Semra; Begec, Zekine; Ozturk, Erdogan; Ersoy, Mehmet Ozcan
    Background: Because patients with major depression have an altered autonomic nervous system activity, the risk of arrhythmias and sudden cardiac death may be increased. In addition, electroconvulsive therapy (ECT) may cause an acute rise in QT dispersion, which may predispose to arrhythmias. In this study, we investigated the effects of propofol or etomidate on the corrected QT (QTc) interval during ECT in patients with major depression. Materials and Methods: Fourteen unpremedicated American Society of Anesthesiologists 1 patients, each scheduled for 6 ECT sessions for major depression, were included in a prospective, randomized crossover study The patients randomly received either 1-mg/kg propofol (propofol group) or 0.2-mg/kg etomidate (etomidate group). The mean arterial pressure (MAY), heart rate (HR), and electrocardiogram were recorded before anesthetic induction, 0 and 1 minute after the seizure ended, and 3 and 10 minutes after the seizure ended (T3 and T4, respectively). Results: In the propofol group, the QTc interval was shorter than the baseline at 0 minute after the seizure ended. The QTc interval increased from the baseline at T3 and T4 in the etomidate group. In the etomidate group, the QTc interval was longer at T3 and T4 than that in the propofol group (P < 0.05). In the etomidate group, the HR increased at T3 and T4, but the MAP increased at all measurement times from the baseline value. The HR and the MAP were lower at T3 and T4 in the propofol group than in the etomidate group (P < 0.05). Conclusions: Propofol did not induce prolongation of the QT interval and controlled the hemodynamic response better than etomidate during ECT. Therefore, propofol may be more suitable than etomidate for ECT treatments.

    The effects of secondhand smoke on postoperative pain and fentanyl consumption
    (Springer Japan Kk, 2013) Aydogan, Mustafa Said; Ozturk, Erdogan; Erdogan, Mehmet Ali; Yucel, Aytac; Durmus, Mahmut; Ersoy, Mehmet Ozcan; Colak, Cemil
    Although the need for increased postoperative analgesia in smokers has been described, the effect of secondhand smoke on postoperative analgesia requirements has not been studied. We examined the effects of secondhand smoke on fentanyl consumption and postoperative pain. In this study, 101 patients (American Society of Anesthesiology physical status I and II) who underwent abdominal hysterectomy were divided into 3 groups according to history of exposure to cigarette smoke as per medical records which was retrospectively confirmed by measurement of serum cotinine: smokers (n = 28), nonsmokers (n = 31), and secondhand smokers (n = 32). All patients received propofol-remifentanil total intravenous anesthesia and used fentanyl patient controlled analgesia for postoperative pain. The fentanyl consumption visual analogue scale-pain intensity (VAS-PI) score and side effects were recorded in the postanesthesia care unit (PACU) and at 2, 4, 6, and 24 h after surgery. Fentanyl consumption at all the evaluation time points was significantly higher in secondhand smokers than in nonsmokers (P < 0.05). However, fentanyl consumption in secondhand smokers was lower than that in smokers in the PACU and at 24 h (P < 0.05). VAS-PI scores during movement and at rest in the PACU and at 4, 6, and 24 h after surgery were higher in secondhand smokers than in nonsmokers (P < 0.05). There were no statistically significant differences between the groups with regard to side effects such as nausea, vomiting, and dizziness (P > 0.05). Secondhand smoking was associated with increased postoperative fentanyl consumption, and increased VAS-PI scores. These findings may be beneficial for managing postoperative pain in secondhand smokers.

    Effects of sevoflurane or ketamine on the QTc interval during electroconvulsive therapy
    (Springer Japan Kk, 2015) Erdil, Feray; Begec, Zekine; Kayhan, Gulay Erdogan; Yologlu, Saim; Ersoy, Mehmet Ozcan; Durmus, Mahmut
    To evaluate the effect of sevoflurane or ketamine on the corrected QT (QTc) interval and the interval from the peak to the end of the T wave (Tp-e) during electroconvulsive therapy (ECT) in patients with major depression. This prospective, randomized, double-blinded study included 24 patients that were randomly allocated to receive sevoflurane (group S) or ketamine (group K) for ECT session. Group S patients received 8 % sevoflurane for anesthesia induction, which was maintained at 2-4 % until delivery of the electrical stimulus. Group K patients received a bolus of ketamine (1 mg/kg). The mean arterial pressure (MAP) and heart rate (HR) and the electrocardiogram (ECG) were recorded before (T1) and after induction of anesthesia (T2) and 0, 1, 3, and 10 min after the electrical stimuli ended (T3, T4, T5, and T6, respectively). In both groups, the QTc interval was significantly longer at T2, T4, T5, and T6 than at baseline. The QTc interval was longer at T4, T5, and T6 in group S compared to that in group K, the Tp-e interval was significantly longer at T4 in group K both baseline and group S. The HR in group S was increased at T4 compared with group K. MAP was significantly higher after induction of anesthesia in group K compared to those in group S at all time points. Although group S showed a prolonged QTc interval after ECT compared to group K, the Tp-e interval in both groups was not significantly affected clinically. Sevoflurane blunted MAP and peak HR.

    Fat Embolism Syndrome in Two Cases with Multiple Fractures
    (Galenos Yayincilik, 2012) Ozgul, Ulku; Gedik, Ender; Karakaplan, Mustafa; Koc, Elif; Koca, Erdinc; Togal, Turkan; Ersoy, Mehmet Ozcan
    Fat embolism is a syndrome which is caused by oil particles introduce into the systemic circulation and consists of respiratory distress, altered consciousness and petechial rashes. It may occur following traumatic, surgical and non-traumatic clinical conditions. The most common occurrence develops following the long bone fractures within 24-72 hours. The clinical picture of syndrome may vary slightly condition as well as respiratory failure and coma. The diagnosis is done based on mostly clinical criteria. There is no specific laboratory and radiographic findings. The suggested supportive approaches in the treatment of this syndrome are early fixation of the fracture, maintenance of fluid and electrolyte balance and treatment of hypoxia. We aimed to present two cases of successful diagnosis and treatment process with fat embolism syndrome following multiple fractures due to in-vehicle traffic accidents.
