Öğe Anesthetic management for cesarean birth in pregnancy with the novel coronavirus (COVID-19)(Elsevier Science Inc, 2020) Yilmaz, Resul; Kilic, Fatma; Arican, Sule; Hacibeyoglu, Gulcin; Suslu, Halime; Koyuncu, Mustafa; Uzun, Sema Tuncer[Abstract Not Availabe]Öğe Brachial plexus block for elbow surgery in a patient with spinal muscular atrophy(Elsevier Science Inc, 2021) Hacibeyoglu, Gulcin; Kocadag, Gokhan; Ozkan, Asiye; Yilmaz, Resul; Arican, Sule[Abstract Not Availabe]Öğe Comparison of Patient Haemodynamics and Cost Analysis between Ketamine and Dexmedetomidine Used for Endoscopic Retrograde Cholangiopancreatography(Istanbul Training & Research Hospital, 2020) Arican, Sule; Yusifov, Merve; Hacibeyoglu, Gulcin; Yilmaz, ResulIntroduction: This study aimed to compare the ketamine-propofol and dexmedetomidine-propofol combinations used for endoscopic retrograde cholangiopancreatography (ERCP) performed under sedation. Primary outcomes were total propofol consumption, recovery and haemodynamic profiles of patients in each study group. Secondary outcomes were sedation-related complications and cost profiles of patients in each study group. Methods: Patients with American Society of Anaesthesiologists class I-III, aged 18-80 years, who underwent ERCP under sedation, were included in the study. Patients were randomly divided into two groups, namely the ketamine group (group KP) and the dexmedetomidine group (group DP). Group KP received 1 mg/kg ketamine plus 1 mg/kg propofol. Group DP received a loading dose of 1 mu g/kg of dexmedetomidine for 10 min and a maintenance dose of 0.5 mu g/kg plus 1 mg/kg of propofol. Moreover, propofol (10-20 mg) was added to keep the Ramsay Sedation scale at >= 3. Cardiopulmonary side effects, nausea, vomiting, hiccups, straining or retching were recorded in all patients. The ERCP procedure duration, as well as the awakening and recovery times, were recorded. Doses and costs of the drugs used were recorded. Patients were discharged when their Modified Alderete score was 10. Results: This study included 80 patients. The duration of ERCP in the groups KP and DP was 23.1 +/- 9.7 min and 24.4 +/- 15.2 min, respectively, and the duration of awakening was 6.0 +/- 3.2 min and 7.3 +/- 2.9 min, respectively. No statistically significant difference was noted. The recovery time was 18.6 +/- 10.6 min and 9.6 +/- 4.0 min in groups KP and DP, respectively, with a statistically significant difference noted. No statistically significant intergroup difference was noted regarding additional propofol doses; however, the total cost was $0.58 +/- 0.16 and $3.03 +/- 0.60 in groups KP and DP, respectively. Conclusion: Both ketamine-propofol and dexmedetomidine-propofol combinations provide safe and effective anaesthesia for ERCP performed under sedation. Even though the recovery time was significantly shorter in group DP, it had a significantly higher cost factor on analysis.Öğe Comparison of pre-operative platelet functions by thromboelastogram in patients selective serotonin reuptake inhibitors user and non-user(Turkish Assoc Trauma Emergency Surgery, 2022) Yilmaz, Resul; Yusifov, Merve; Hacibeyoglu, Gulcin; Arican, Sule; Topal, AhmetBACKGROUND: The use of antidepressant drugs, in particular selective serotonin reuptake inhibitors (SSRIs), has increased in recent years. Using SSRIs can cause changes in serotonin metabolism. Serotonin provides platelet aggregation and plays a role in the regulation of vascular tone and coagulation processes. The aim of this study was to evaluate the effects of SSRI use on coagulation functions with thromboelastogram (TEG) in patients undergoing surgical operation and to compare with non-user cases. METHODS: The study was designed for 60 patients whose physical status was classified according to the American Society of Anes-thesiology (ASA) classification as ASA I-II were included in the study. During routine pre-operative blood tests, 2 ml complete blood sample used and TEG performed. The cases were divided into two groups as SSRI user and non-user and analyzed. RESULTS: R value was higher in SSRI user patients than in non-user patients. The MA value was significantly lower in SSRI user. There was no statistically significant difference in other parameters. In the evaluation based on duration of SSRI use, there was no statistically significant difference between those whose duration of use was more than 1 year and <1 year. CONCLUSION: When the coagulation process was evaluated by TEG method, it was seen that the onset of clotting was prolonged and thrombus formation was slowed down in SSRI users. The results did not reveal that SSRI alone was the cause of bleeding, but it was concluded that slowing the process might be important, especially for surgical operations.Öğe Comparison of pre-operative platelet functions by thromboelastogram in patients selective serotonin reuptake inhibitors user and non-user(Turkish Assoc Trauma Emergency Surgery, 2022) Yilmaz, Resul; Yusifov, Merve; Hacibeyoglu, Gulcin; Arican, Sule; Topal, AhmetBACKGROUND: The use of antidepressant drugs, in particular selective serotonin reuptake inhibitors (SSRIs), has increased in recent years.

We aimed to assess the effects of levobupivacaine and of levobupivacaine + adrenaline administered during pediatric tonsillectomy on the postoperative period. Methods. A total of 90 patients between the ages of five and twelve were divided randomly into two groups before tonsillectomy: levobupivacaine only (0.5%) 0.4 mg.kg(-1) or levobupivacaine (0.5%) 0.4 mg.kg(-1) + adrenaline (1 :200.000) administered by means of peritonsillar infiltration. Primary outcomes were postoperative pain scores recorded at various intervals until 24 hours postoperatively. Secondary outcomes included postoperative nausea and vomiting (PONV), time to first oral intake, time to the first administration of analgesics and total consumption of analgesics, and the amount of bleeding for all children. Results. In both groups, patients had the same postoperative pain scores and PONV rates, and equal amounts of analgesics were consumed up to 24 hours postoperatively. The two groups also had the same time until first oral intake, recovery time and time to the first analgesic request, and amount of bleeding. Conclusions. Perioperative levobupivacaine infiltration on its own is a valid alternative to the combination of levobupivacaine + adrenaline for perioperative and postoperative effectiveness in pediatric tonsillectomy.Öğe The effect of low dose ionizing radiation exposure on dynamic thiol-disulfide homeostasis and ischemia modified albumin levels: an observational study(Elsevier Science Inc, 2020) Arican, Sule; Dertli, Ramazan; Baktik, Suleyman; Hacibeyoglu, Gulcin; Erol, Atilla; Ulukaya, Sinan Oguzhan; Goger, EsraBackground: The primary objective of this study was to investigate the effect of low dose ionizing radiation exposure on thiol/disulfide homeostasis and ischemia modified albumin levels. The secondary objective is to compare thiol/disulfide homeostasis and ischemia modified albumin levels among the personnel exposed to low dose ionizing radiation in anesthesia application areas, in and out of the Operation room. Methods: The study included a total of 90 volunteers aged between 18 and 65 years old, with 45 personnel working in a setting with potential for radiation exposure (Exposed Group) and 45 personnel in a setting without radiation exposure (Control Group). Their native thiol, total thiol, disulphide, albumine and IMA levels were measured. Exposed group included personnel who were exposed to radiation outside the operating room - Operation room (-) Group and inside the Operating room - Operation room (+) Group. Results: Albumin, native and total thiol levels were significantly lower in the participants exposed to radiation in the anesthesia application area, no statistically significant difference was found in terms of disulfide and ischemia modified albumin levels. In the Operation room (-) group exposed to radiation, native thiol and total thiol values were significantly lower compared to the Operation room (+) groups. Conclusion: Awareness of being in danger of oxidative stress should be established in personnel exposed to radiation in the anesthesia application area following low dose ionizing radiation exposure, and the necessary measures should be taken.

Postoperative pain, edema, and periorbital ecchymosis are the most common acute complications of this surgical procedure. In this study, we aimed to evaluate the postoperative pain and analgesic consumption after rhinoplasty of patients who had bilateral supraorbital and infraorbital nerve block. Methods: Eighty-four patients who underwent rhinoplasty under general anesthesia, between 17 and 41 years of age, and who underwent intravenous patient-controlled morphine analgesia for postoperative analgesia were included in this study. The cases were divided into two groups: bilateral supra-infraorbital block with intravenous analgesic (Group B) and only intravenous analgesic (Group C). Demographic data, hemodynamic data, operation time, visual analog scale values, patient-controlled analgesia device data, complaints of nausea-vomiting, and antiemetic drug use were recorded. Results: The hemodynamic data of the cases included in this study were similar (P > .05). When compared with Group C, postoperative 1st, 6th, and 24th hour visual analog scale (VAS) scores were found to be significantly lower in Group B (P < .05). Morphine consumption at the end of the postoperative 24 hours was found to be significantly lower in Group B compared with Group C (P < .05). Conclusion: In this study, which cases undergoing bilateral supraorbital-infraorbital nerve block and IV morphine was used for postoperative analgesia after rhinoplasty, significant reductions were achieved in the postoperative VAS values and analgesic consumption of the cases where the block was used.Öğe The effects of sevoflurane anesthesia on hemodynamics and cerebral artery diameters in endovascular treatment of intracranial aneurysm: A pilot study(Turkish Assoc Trauma Emergency Surgery, 2021) Arican, Sule; Bakdik, Suleyman; Hacibeyoglu, Gulcin; Yilmaz, Resul; Koc, Osman; Tavlan, Aybars; Uzun, Sema TuncerBACKGROUND: Cerebral autoregulation is a steady-state of cerebral blood flow despite major changes in arterial blood pressure. Inhalation anesthetics are cerebral vasodilators. In <1 MAC values, the net effect is a moderate decrease in cerebral blood flow and maintenance of responsiveness to carbon dioxide. This study aims to investigate the effects of steady-state sevoflurane anesthesia on hemodynamic and cerebral artery diameter measurements in patients undergoing flow diverter device placement under general anesthesia. METHODS: Forty-six patients aged 18-70 years who underwent flow diverter devices under general anesthesia were included in this study. Routine monitoring was performed on the patients. Mean arterial pressure (MAP) values were recorded. Internal carotid artery, middle cerebral artery and anterior cerebral artery diameter measurements were made from digital subtraction angiography (DSA) images of patients with anterior aneurysms. Baseline artery, right posterior cerebral artery and left posterior cerebral artery diameter measurements were made from DSA images of patients with posterior aneurysms. These measurements were recorded as preoperative measurements. The same measurements were made from the DSA images performed before the Flow diverter device placement procedure performed under steady-state sevoflurane anesthesia for the same patients. These measurements were recorded as peroperative measurements. RESULTS: The average age of the patients was 56.6 +/- 15.1. The MAP of the patients before induction was 76.28 +/- 5.13 mmHg, MAP after induction was 64.36 +/- 3.23 mmHg, and MAP during sevoflurane anesthesia was 68.26 +/- 4.30 mmHg, there was a statistically significant difference. There was a statistically significant difference between the preoperative and perioperative values of anterior cerebral artery diameters. There was a strong relationship between the MAP change percentage and the ICA diameter change percentage (p<0.001, p=-0.785) and a moderate relationship between the MCA diameter change percentage (p=0.033, p=-0.338). CONCLUSION: In patients undergoing flow diverter devices, <1 MAC sevoflurane has a hemodynamic effect and creates significant vasodilation in the cerebral artery diameters.Öğe The effects of sevoflurane anesthesia on hemodynamics and cerebral artery diameters in endovascular treatment of intracranial aneurysm: A pilot study(Turkish Assoc Trauma Emergency Surgery, 2021) Arican, Sule; Bakdik, Suleyman; Hacibeyoglu, Gulcin; Yilmaz, Resul; Koc, Osman; Tavlan, Aybars; Uzun, Sema TuncerBACKGROUND: Cerebral autoregulation is a steady-state of cerebral blood flow despite major changes in arterial blood pressure.

The albumin cobalt binding test was used to measure serum IMA levels. Results: Serum IMA levels were 1.21 +/- 0.58 AU and 0.75 +/- 0.09 AU in the PHN and control groups, respectively (p <0.001). Serum total thiol concentrations were found to be 421.62 +/- 90.28 mu mol/L and 598.36 +/- 73.63 mu mol/L in the PHN and control groups, respectively (p <0.001). Serum native thiol concentrations were found to be 365.75 +/- 92.07 mu mol/L and 531.90 +/- 72.9 mu mol/L in the PHN and control groups, respectively (p < 0.001). Serum disulfide concentrations were found to be 33.23 +/- 5.33 mu mol/L and 27.93 +/- 7.81 mu mol/L in the PHN and control groups, respectively (p= 0.003). The native thiol/total thiol ratio was significantly lower, and the disulfide/total thiol and disulfide/native thiol ratios were significantly higher in the PHN group compared to the controls. Conclusions: IMA levels are high and dynamic thiol/disulfide homeostasis is disrupted in PHN patients.
