I.; Yilmaz, S.[Abstract Not Available]Öğe The effect of spinal anesthesia that is performed in sitting or right lateral position on post-spinal headache and intraocular pressure during elective cesarean section(Wolters Kluwer Medknow Publications, 2023) Dogukan, M.; Bicakcioglu, M.; Yilmaz, N.; Duran, M.; Uludag, O.; Tutak, A.; Kaya, R.Background: Although spinal anesthesia can be applied in different patient positions, the most frequently used positions are sitting and lateral positions. It is known that different patient positions during spinal anesthesia have effects on hemodynamic parameters, postdural puncture headache, and intraocular pressure.Aim: The study aimed to determine the effect of spinal anesthesia performed in either sitting or right lateral position on postspinal headache and intraocular pressure during elective cesarean section. Patients and Methods: The study was a randomized controlled study of 104 eligible pregnant women scheduled to undergo elective cesarean section. The women were randomized into two groups. Spinal anesthesia was performed either in the sitting (Group S, n = 53) or the right lateral position (Group L, n = 51). Heart rate and blood pressure were recorded throughout the operation. The participants were informed and monitored for postspinal headaches. Intraocular pressure before and after the operation was measured with Icare PRO. The obtained data were statistically compared between the two groups.Results: There was no difference between the groups in terms of demographic data. Postdural puncture headache was observed in five patients in Group S and one patient in Group L (P =0.04). There was no difference between the groups in terms of intraocular pressure (P >.05). Heart rate was not significantly different between the groups; however, there was a significant difference in average blood pressure in 1, 5, 30, and 40 minutes (P <.05). The number of trials administered to patients for spinal anesthesia was significantly higher in Group L (P =0.01).Conclusion: Spinal anesthesia performed in the sitting position for cesarean section caused a higher postspinal headache than in the right lateral position, but the position did not affect intraocular pressure.Öğe Effects of Different Positive End-Expiratory Pressure Values on Liver Function and Indocyanine Green Clearance Test in Liver Transplantation Donors: A Prospective, Randomized, Double-Blind Study(Elsevier Science Inc, 2015) Bicakcioglu, M.; Aydogan, M. S.; Sayan, H.; Toprak, H. I.; Isik, B.; Yilmaz, S.; Yologlu, S.Introduction. The aim of this study was demonstrate the influence of different positive end-expiratory pressure (PEEP) values on blood flow of the liver by indocyanine green (ICG) clearance test in donor patients. Methods. ICG clearance tests were conducted concurrently using a noninvasive monitor that tracks the plasma disappearance rate of ICG (PDR-ICG%/min) and 15-minute retention rate after administration of ICG (ICG-R15%). This study was performed in 40 patients who underwent right hepatectomy. Results. The positive end-expiratory pressure (PEEP) was 0 cm H2O in the first (control) group (group K) and 10 mm Hg in the second study group (group P). ICG clearance test values before general anesthesia (T0), after induction of general anesthesia (T1), after transection (T2), 24 hours postoperative (T3), and 72 hours postoperative (T4) were recorded. Simultaneously, hemoglobin (Hgb), hematocrit (Hct), platelet count, plasma levels of prothrombin (PT), International Normalized Ratio (INR), total bilirubin, direct bilirubin, albumin, aspartate aminotransferase, and alanine aminotransferase values were analyzed. In terms of the plasma disappearance rate and retention rate of ICG 15 minutes after administration, significant difference was not observed between groups. PT and INR values were different within comparisons groups (P < .05). There were significant differences in Hgb and Hct values compared with the baseline values (T0) within group (T1, T2, T3, T4) measurements and between group comparisons at T0 and T4 (P < .05). Systemic arterial pressure, mean arterial pressure, and central venous pressure were significantly different between the groups (P <.05). Conclusions. Given the small magnitude and limited clinical significance of these changes, we conclude that PEEP values between 0 and 10 cm H2O have no effect on global liver function and liver-related liabilities tests in patients undergoing elective liver donor surgery.Öğe Effects of Thoracic Epidural Anesthesia on Liver Blood Flow and Indocyanine Green Clearance Test in Living-Donor Liver Transplantation: A Prospective, Randomized, Double-Blind Study(Elsevier Science Inc, 2015) Sayan, H.; Aydogan, M. S.; Bicakcioglu, M.; Toprak, H. I.; Isik, B.; Yilmaz, S.Background. Donors are volunteers without any health problems. Therefore, the anesthetic management of donor safety is an important issue. Our aim in this study was to compare thoracic epidural anesthesia and general anesthesia effects on liver blood flow by means of liver function tests and indocyanine green and compared with living-donor liver transplantation. Methods. Subjects were divided into 2 equal groups: the control group (group I) and the epidural block group (group II, closed envelope method). In group II patients, the epidural catheter was inserted at the T6-8 level. In all patients, anesthesia was standardized with the use of lidocaine, fentanyl, and thiopental. Indocyanine green clearance test values before general anesthesia (T0), after induction of general anesthesia (T1), after transection (T2), and at postoperative 24 and 72 hours were recorded. Simultaneously, hemoglobin, hematocrit, platelet count, prothrombin time (PT), international normalized ratio (INR), total bilirubin, direct bilirubin, albumin, aspartate transaminase, and alanine transaminase values were analyzed. Results. Plasma disappearance rate (PDR) and retention at 15 minutes (R15) of indocyanine green were not statistically significant difference between groups (P > .05). Intragroup comparison of PDR and R15 values at times T1, T2, T3, and T4 showed that the values at T0 were statistically significant (P < .05). PT and INR values were significantly different for all times within each group (P < .05). It was concluded that the use of thoracic epidural anesthesia has no effect on global liver function and liver-related liability tests in patients undergoing elective liver donor surgery.Öğe Effects of Two Different Techniques of Postoperative Analgesia Management in Liver Transplant Donors: A Prospective, Randomized, Double-Blind Study(Elsevier Science Inc, 2015) Aydogan, M. S.; Bicakcioglu, M.; Sayan, H.; Durmus, M.; Yilmaz, S.The aim of this study was the compare the donor patients who received intravenous (IV) morphine with patient-controlled analgesia (PCA) or epidural morphine during the early postoperative period who underwent liver transplantation. Forty patients were included in the study and randomly divided into 2 groups in a double-blinded manner. They were given IV morphine 5 mg (Group C), or epidural anesthesia adding morphine (2 mg; Group E) by epidural anesthesia technique starting 15 minutes before the estimated time of completion of surgery. All of the patients received PCA with IV morphine (Group C; PCA device was set to deliver 1 mg morphine with a lockout of 15 minutes and a 4-hour limit of 20 mg, and no continuous infusion) or epidural morphine (Group E; patient-controlled epidural analgesia [PCEA] device was set to deliver 0.5 mg morphine with a lockout of 30 minutes and a 4-hour limit of 10 mg, and no continuous infusion) and were followed up for 24 hours, and pain scores were evaluated by study nurses who were blinded to the study protocol. The visual analogue scale (VAS) scores at rest and at movement and morphine consumption at 12 and 24 hours after operation evaluation time points were significantly higher in Group E than those in Group C (P < .05). Furthermore, total morphine consumption in Group C was significantly higher than that in Group E (P < .05). Epidural morphine via PCEA was associated with decreased postoperative VAS scores and morphine consumption. These findings may be beneficial for managing postoperative analgesia protocols in liver transplant donor patients.Öğe Foodborne botulism: 4 cases report(Elsevier Ireland Ltd, 2016) Bicakcioglu, M.; Aydogan, M. S.; Yucel, A.; Togal, T.[Abstract Not Available]Öğe Inhaled nitric oxide as rescue therapy in severe ARDS cases due to COVID-19 pneumonia: a single center experience(Verduci Publisher, 2023) Bicakcioglu, M.; Kalkan, S.; Duzenci, D.; Yalcinsoy, M.; Dogan, Z.; Ozer, A. B.OBJECTIVE: Inhaled NO (iNO) has been recommended as rescue therapy in acute respiratory stress syndrome (ARDS) cas-es. In this study, we aimed to demonstrate the efficacy of iNO as a rescue therapy in patients with severe ARDS due to COVID-19.PATIENTS AND METHODS: This retrospec-tive study included patients with ARDS due to COVID-19 who were treated with iNO between March 2020 and January 2022 in the intensive care unit (ICU) of Inonu University. Patients' files were reviewed retrospectively, and de-mographic data, APACHE II and Sequential Or-gan Failure Assessment (SOFA) scores, initia-tion day of iNO and duration of iNO treatment, length of stay in hospital/ICU, blood biochem-istry values, complete blood counts, inflamma-tory parameters, arterial blood gas values, lac-tate, PaO2/FiO2 ratios, anti-inflammatory drugs and outcome were recorded.RESULTS: Data from 16 patients were reached. iNO was given at a dose of 20 ppm continuously. The mean duration of treatment with iNO was 3.5 days. All patients took the prone position except a single patient. While all patients received steroid therapy, four pa-tients received anti-cytokine therapy, and five patients received intravenous immunoglobulin therapy. All patients were in severe ARDS with a mean PaO2/FiO2 ratio of 58 before iNO ther-apy. A significant increase in PaO2/FiO2 val-ues was detected with the use of iNO (p<0.05). While three patients (19%) were discharged from the ICU, thirteen patients died.CONCLUSIONS: In our study, it was deter-mined that iNO applied as a rescue treatment in patients with severe ARDS improved oxygen-ation. Although the effect of iNO on survival was low, it may be interpreted as clinically signifi-cant considering the severity of the general clin-ical condition of the patients.Öğe Tracheomediastinal emphysema after tracheostomy in a post-COVID-19 patient: a case report(Verduci Publisher, 2022) Bicakcioglu, M.; Demircan, S.; Yucel, A.; Ozer, A. B.OBJECTIVE: There are no reports of tracheomediastinal fistula development after tracheostomy. CASE REPORT: A 72-year-old female patient with post acute COVID-19 was transferred to our intensive care unit. After two unsuccessful weaning attempts, a tracheostomy was performed at hospitalization on day 32. The patient's body mass index was 35 kg/m2 and she had a narrow neck anatomy. A percutaneous tracheostomy was performed using the Griggs method without any problems. Pneumothorax, pneumomediastinum, subcutaneous emphysema, and hemorrhage were not observed. Twenty-two days after the tracheostomy, the patient developed subcutaneous emphysema and experienced a sudden decrease in oxygen saturation. Bedside anterior-posterior chest X-ray did not detect pneumothorax and a tracheoesophageal fistula was found via esophageal endoscopy. A tracheomediastinal fistula was observed just below the cannula distal end via computed tomography. CONCLUSIONS: There are multiple reasons why a tracheomediastinal fistula could develop after tracheostomy. Therefore, this condition should be considered in cases of sudden subcutaneous emphysema and oxygen deterioration following tracheostomy.
