Öğe Effects of Desflurane and Isoflurane on Hepatic and Renal Functions and Coagulation Profile During Donor Hepatectomy(Elsevier Science Inc, 2012) Toprak, H. I.; Sahin, T.; Aslan, S.; Karahan, K.; Sanli, M.; Ersoy, M. O.We compared the effect of two inhalation anesthetics desflurane and isoflurane on postoperative hepatic and renal functions as well as coagulation profiles in living donors undergoing right hepatectomy. This study was performed on 80 patients who were randomly allocated to group D (desflurane, n = 40) or group I (isoflurane, n = 40) after Faculty Ethics Committee approval. After induction, isoflurane or desflurane was used with air/oxygen for anesthetic maintenance. The isoflurane or desflurane concentration was set at one minimum alveolar concentration (MAC). Remifentanil was infused for analgesia as well as cisatracurium. Aspartate aminotransferase (AST), alanine aminotransferase (ALT), international normalized. ratio (INR), albumin, total bilirubin, blood urea nitrogen, creatinine, platelet count, and hemoglobin levels were analyzed preoperatively at end of the operation, and on postoperative days (PODs) 1, 2, 3, 5, 7, and 30. Both AST and ALT differed significantly and continually except on POD 30. AST showed significant elevations from the end of the operation to POD 2 and ALT, from the end of the operation to POD 5 in group I compared with group D. INR was significantly higher from the end of the operation to POD 3 in group I and to POD 2 in group D. At the end of the operation as well as on POD 1 and POD 2, INR was significantly increased in group I compared with group D. Albumin level was significantly lower at the end of the operation in both groups, but it was not different. No patient developed hepatic or renal failure. Our study showed better postoperative hepatic tests and INR using desflurane than isoflurane at equivalent. doses of 1 MAC in living donors undergoing right hepatectomy.Öğe The risk facotrs of mortality following liver transplantation in acute liver failure: Single center experience(Lippincott Williams & Wilkins, 2019) Sahin, T.; Sarici, K.

Erdogan; Toprak, H. I.; Sahin, T.; Konur, H.; Colak, C.; Durmus, M.We compared the effectiveness of three anaesthetic regimens (propofol alone, propofol with remifentanil and sevoflurane alone), with respect to seizure duration and seizure quality in patients undergoing electroconvulsive therapy. Thirty-nine patients underwent a total of 234 electroconvulsive therapy treatments in this prospective, observer blinded, crossover study. Each patient received either propofol 1 mg/kg alone (Group P), propofol 0.5 mg/kg and remifentanil 1 mu g/kg (Group R), or sevoflurane alone 6% (Group S) for their initial electroconvulsive therapy session. The patients subsequently received an alternative regimen in their next session, such as from propofol 1 mg/kg alone to propofol 0.5 mg/kg and remifentanil 1 mu g/kg, from propofol 1 mg/kg alone to propofol 0.5 mg/kg and remifentanil 1 mu g/kg to sevoflurane alone 6%, or from sevoflurane alone 6% to a continuing alternation between drugs at each session, until their sixth session. Muscle paralysis was achieved with 1 mg/kg succinylcholine. Seizure duration, postictal suppression index, early and midictal amplitude were recorded. The mean motor and electroencephalogram seizure durations were significantly longer in Groups P and R compared to Group S (P <0.001). The postictal suppression index and early and midictal amplitude values were not significantly different among the groups. These findings indicate that the three anaesthetic regimens had similar effects on seizure quality parameters, although sevoflurane was associated with shorter seizure durations than propofol or propofol-remifentanil.Öğe Totally laparoscopic resection and extraction of specimens via transanal route in synchronous colon and gastric cancer(Cic Edizioni Int, 2018) Sumer, F.; Karakas, S.; Gundogan, E.; Sahin, T.; Kayaalp, C.Introduction. Synchronous colon and gastric cancer is a rare clinical entity. In the present case, it is aimed to show that in a patient with synchronous colon and gastric cancer, laparoscopic resection can be safely performed and both specimens can be delivered through a natural orifice. In our knowledge, this is the first example showing the delivery of the gastric resection specimen through the anus in a human being. Case report. Sixty-six years old male patient with an upper gastrointestinal bleeding and obstruction symptoms was admitted to our department and the evaluation revealed an advanced stage gastric and a synchronous colon cancer. A laparoscopic palliative subtotal gastrectomy with a subtotal colectomy was performed. All anastomoses were performed intracorporeally and colectomy and subtotal gastrectomy specimens were successfully delivered via trans-anal route without any difficulty. Despite major abdominal organ resections, the patients required quite less analgesics in the postoperative period. Discussion. Specimen extraction through the natural orifices eliminates the need and problems of performing additional abdominal incisions to the patients which also leads to reduced postoperative pain. Synchronous surgical procedures do not prevent the natural orifice surgery.
