    Effectiveness of clonidine and fentanyl addition to bupivacaine in postoperative patient controlled epidural analgesia
    Topcu, I; Luleci, N; Tekin, S; Kefi, A; Erincler, T
    Background and Objectives: The aim of this prospective randomized double-blinded study was to compare the analgesic and side-effects of bupivacaine in combination with clonidine or fentanyl during patient-controlled-epidural analgesia (PCEA) in the postoperative period after abdominal hysterectomy. Methods: 75 patients from 18 to 65 years of age with ASA status I - II were investigated. After preoperative epidural catheterization, the patients were operated in general anesthesia. After surgery, the patients were randomly allocated to 3 PCEA-groups: Group B 0.125% bupivacaine, Group F 0.125% bupivacaine plus 1 mu g x ml(-1) fentanyl, Group C 0.125% bupivacaine plus 0.75 mu g x ml(-1) clonidine (10 ml loading dose, 5 ml repetitive bolus dose, 10 min lockout time, 30 ml limit within 4h). During the following 24 hours, hemodynamic parameters, pain score using visual analog scale (VAS), total analgesic consumption, additional analgesic requirements, sedation, satisfaction, nausea scores and probable side-effects were evaluated. Results: Total analgesic consumption was not different between Group F and Group C, but lower than in Group B (p < 0.05). Additional analgesic use was not different between the groups. Group F and Group C had lower VAS-scores in 24 hours than Group B (p < 0.05). Hemodynamic and sedation scores of patients were not different. In Group C, incidence of nausea was lower and satisfaction of patients was higher (p < 0.05). Conclusions: Addition of clonidine or fentanyl to local anesthetics for PCEA can reduce the analgetic demand. Epidural clonidine can reduce postoperative nausea and is connected with higher patients' satisfaction.

    Seizures, metabolic acidosis and coma resulting from acute isoniazid intoxication
    Topcu, I; Yentur, EA; Kefi, A; Ekici, NZ; Sakarya, M
    Isoniazid is an anti-tuberculosis drug, used commonly for treatment and prophylaxis of tuberculosis. Acute isoniazid intoxication is characterized by a clinical triad consisting of metabolic acidosis resistant to treatment with sodium bicarbonate, seizures which may be fatal and refractory to standard anticonvulsant therapy, and coma. Treatment requires admission to the intensive care unit for ventilatory support, management of seizures and metabolic acidosis. Pyridoxine, in a dose equivalent to the amount of isoniazid ingested, is the only effective antidote. We report the successful treatment of two isoniazid intoxication cases: the case of a child developing an accidental acute isoniazid intoxication and an adult case of isoniazid intoxication with the intent of suicide.

    Acute Kidney Injury Incidence According to The RIFLE Criteria and Risk Factors in Critically Ill Patients
    Karagoz, P; Kefi, A; Dündar, PE; Canan, S; Çivi, M
    Objective: In our study, it was aimed to investigate the relationship between RIFLE classification and the risk factors such as acute renal failure incidence, kidney failure in terms of comorbid conditions, critical conditions before and after hospitalization, if any, genetic predispositions, drug use, scores on administration day to the hospital and mortality in intensive care unit patients. Material and Method: A total of 200 patients hospitalized in anesthesiology and reanimation intensive care unit (ICU) between March 1, 2012 and March 31, 2013 were prospectively evaluated. The patients with a history of established chronic renal failure or hemodialysis, under 18 years of age and the patients hospitalized in ICU less than 48 hours were excluded. Data of the patients regarding age, gender, body mass index (BMI), diagnosis at the hospitalization, history of any operation, smoking status, medications, durations of ICU stay and mechanical ventilation, SOFA and APACHE II scores on the 1st day, the worst RIFLE score during the hospitalization, medical status at the end were recorded. The patients whom creatinine levels were not increased significantly and/or GFR and urine output were not decreased were accepted as out of RIFLE. Results: Age, BMI, diagnosis at the hospitalization, smoking status, presence and duration of chronic disease, analgesia, antibiotic and diuretic usages, presences bleeding and hypotension episodes, mechanical ventilation and total ICU hospitalization durations, SOFA and APACHE II scores on the 1st day were found to be significantly related to RIFLE classification. Gender, history and type of operation, type of chronic disease, glucocorticoids, HES, radiocontrast drug administration, renal stone disease, familial renal disease history were not found significantly related. Increased RIFLE scores were found to be related with increased mortality. Conclusion: We concluded that recognizing the factors leading to renal injury/failure and usage of RIFLE classification in daily care of patients are important to decrease mortality and morbidity of ICU patients by increasing the awareness.
