Item Fatal Outcome After Renal Transplant in a Pediatric Patient With Noonan Syndrome(2015) Araz, Coskun; Kaval, Ebru; Torgay, Adnan; Moray, Gokhan; Haberal, Mehmet; 0000-0003-2498-7287; 0000-0002-6829-3300; 0000-0002-4927-6660; 0000-0002-3462-7632; 25894171; AAE-1041-2021; AAJ-5221-2021; AAJ-4576-2021; AAJ-8097-2021Noonan syndrome is a congenital, common, hereditary disorder. Facial dysmorphism, growth retardation, and various heart defects are typical clinical features. In patients with minor cardiac pathology, life expectancy is normal. We report a case of renal transplant in a pediatric patient with Noonan syndrome that ended with death of the patient. Our patient presented with unexpected and refractory postoperative neurological complications that were unresponsive to intensive therapy, and the patient died because of secondary complications.Item Anesthesia Management of a Deceased Cadaveric-Donor Combined Liver and Kidney Transplant for Primary Hyperoxaluria Type 1: Report of a Case(2015) Ersoy, Zeynep; Araz, Coskun; Kirnap, Mahir; Zeyneloglu, Pinar; Torgay, Adnan; Arslan, Gulnaz; 0000-0003-2312-9942; 0000-0003-0767-1088; 0000-0002-6829-3300; 0000-0002-4927-6660; 26640925; AAH-9198-2019; C-3736-2018; AAF-3066-2021; AAJ-5221-2021; AAJ-4576-2021Primary hyperoxaluria type 1 is an autosomal recessive disorder that is responsible for the overproduction of oxalate and has an incidence of 1 in 120 000 live births. Indications for combined liver and kidney transplant are still debated. However, combined liver and kidney transplant is preferred in various conditions, including primary hyperoxaluria, liver-based metabolic abnormalities affecting the kidney, and structural diseases affecting both the liver and the kidney, such as congenital hepatic fibrosis and polycystic kidney disease. When compared with sequential liver and kidney transplant, the rejection rate of both liver and kidney allografts was reported to be lower than with combined liver and kidney transplant. With proper anesthesia management, the probable increased complications with combined liver and kidney transplant can be prevented. In this report, we present the anesthesia care of a 22-year-old patient with primary hyperoxaluria type 1 who had deceased-donor combined liver and kidney transplant.Item Case Reports: Should We Do Away with Them?(2017) Firat, Aynur Camkiran; Araz, Coskun; Kayhan, Zeynep; 0000-0002-4927-6660; 0000-0003-0579-1115; 0000-0003-1470-7501; 28235534; AAJ-4576-2021; AAJ-4623-2021Study objective: There has been a gradual decline in the number of case reports published in leading medical journals in recent years. Since case reports are not highly cited they have an adverse effect on the journal impact factor. On the other hand sharing new experiences, challenges, or discoveries with colleagues is essential for medical community. Should case reports be eliminated from the journals or published only in journals devoted to case reports? Design: Observational study. Setting: Web of Science database was searched, between 2005 and 2009, with terms: "anesthesia", "anesthesiology" and "case report" yielding 25 969, 9532, and 661 publications, respectively. Since some reports contained large number of cases, only those involving up to three cases (n = 425) were evaluated by the authors with respect to their type, contribution to knowledge and/or practice (Likert scale) and times they were cited. Main results: Distribution of answers to the statement "Case has added to my knowledge and/or improved my practice" was; 3% (strongly disagree), 10.5% (disagree), 33.2% (neither agree nor disagree), 39.3% (agree) and 13.7% (strongly agree). Average citations per item was 4.43 (1883/425), 7.32 (4838/661), and 7.82 (74 529/ 9532). As to the types of the reports; 50% unexpected event in the course of anesthesia, 31% unusual and instructive cases, 9.6% novel/unique anesthetic techniques, 6% novel use of equipment, 1.6% new information on diseases of importance to anesthesiology and 1% scientific observations. Conclusion: Case reports have been an important source of clinical guidance and scientific insight, and play an important role in medical education. They can be published quickly, providing publication opportunity for juniors and for clinicians who may not have the time or finance to conduct large-scale research. On the other hand some argue, that case reports are irrelevant in current medical practice and education, being at the bottom of the hierarchical ladder of medical evidence. We conclude that case reports should not be done away with but be published in websites and journals like the venue to be launched in 2013 by the International Anesthesia Research Society, devoted entirely to them to meet the need for the publication of interesting cases.

In our retrospective study, in septorhinoplasty operations performed under general anesthesia, trigeminocardiac reflex development was investigated primarily during the periods where the reflex was surgically stimulated. Secondly, the effect of different inhalation anesthetic agents on the emergence of this reflex was investigated. Methods: Anesthesia notes and Datex Ohmeda icentral central monitor records of septorhinoplasty cases operated between 01 / January / 2016 - 30 / November / 2016 were retrospectively examined and detected through the Hospital Information Management System software. Induction, application of local anesthesia, surgical incision, initiation of incision suturing and 5 minutes after extubation were recorded from the records. It was determined that two different inhalation anesthetics were administered in 60 patients who met the criteria, and analyzes were performed in 2 separate groups as group sevoflurane and group desflurane, and the development of QT, QTc and Trigeminocardiac reflex was investigated. Results: Although there was no difference between the groups, when the basal values were compared with the other periods, it was found that the development of TKR and QT and QTc experts were mostly observed in the periods of local anesthesia, surgical incision and incision suturing. (p <0.001). Conclusions: We think that the inhalation anesthetic agents used mostly in the sevoflurane group play a facilitating role in the development of TKR, especially by creating a cumulative effect during periods when the trigeminal nerve is maximally stimulated.Item EVALUATION AND MANAGEMENT OF DIFFICULT AIRWAY IN OBESITY: A SINGLE CENTER RETROSPECTIVE STUDY(2016) Ayhan, Asude; Kaplan, Serife; Kayhan, Zeynep; Arslan, Gulnaz; 27276769The primary aim of this single center retrospective study was to evaluate difficult mask ventilation (DMV) and difficult laryngoscopy (DL) in a unique group of obese patients. A total of 427 adult patients with body mass index (BMI) >= 25 and surgically treated for endometrial cancer from 2011 to 2014 were assessed. Additional increase in BMI, comorbidities, bedside screening tests for risk factors, and the tools used to manage the patients were noted and their effects on DMV and/or DL investigated. Every escalation in the number of risk factors increased the probability of DMV 2.2-fold, DL 1.8-fold and DMV+DL 3.0-fold. Among bedside tests, limited neck movement (LNM), short neck (SN) and absence of teeth were significant for DMV (p<0.05), LNM, SN and obstructive sleep apnea for DL (p<0.05), and LNM and SN for DMV+DL (p<0.05). However, a 10-point increase of BMI was not an independent risk factor when patients with BMI >25% were considered. In conclusion, LNM and SN are independent risk factors for developing DMV and/or DL in obese endometrial cancer patients, while BMI increase over 30 was not additionally affecting difficult airway.Item Smartphone use habits of anesthesia providers during anesthetized patient care: a survey from Turkey(2016) Pinar, Huseyin Ulas; Karaca, Omer; Dogan, Rafi; Konuk, Ummu Mine; 0000-0003-0473-6763; 0000-0003-1933-2075; 27716076; Q-2420-2015; AAU-6923-2020Background: Smartphones are used in many areas of anesthesia practice. However, recent editorial articles have expressed concerns about smartphone uses in the operating room for non-medical purposes. We performed a survey to learn about the smartphone use habits and views of Turkish anesthesia providers. Methods: A questionnaire consisting of 14 questions about smartphone use habits during anesthesia care was sent anesthesia providers. Results: In November-December 2015, a total of 955 participants answered our survey with 93.7 % of respondents responding that they used smartphones during the anesthetized patient care. Phone calls (65.4 %), messaging (46.4 %), social media (35.3 %), and surfing the internet (33.7 %) were the most common purposes. However, 96.7 % of respondents indicated that smartphones were either never or seldom used during critical stages of anesthesia. Most respondents (87.3 %) stated that they were never distracted because of smartphone use; however, 41 % had witnessed their collagues in such a situation at least once. Conclusions: According to the results of the survey, smartphones are used in the operating room often for non-medical purposes. Distraction remains a concern but evidence-based data on whether restrictions to smartphone use are required are not yet available.Item Böbrek transplantasyonunda genel ve epidural anestezinin tam kan sayımı, lökosit subgrupları ve natural killer hücre sayısına etkisi(Anestezi Dergisi ,15 ,4 ,260-266, 2007) Aral, Ebru; Dönmez, Aslı; Arslan, Gülnaz; Haberal, Mehmetİmmün sistemi üremi nedeniyle süprese olan kronik böbrek yetmezlikli (KBY) hastalarda genel ve epidural anestezi uygulamalarının immün istem üzerine etkisi iyi bilinmemektedir. Çalışmamızın amacı, böbrek transplantasyonu yapılacak olan hastalarda genel ve epidural anestezinin immüniteye ve tam kan sayımına etkilerini araştırmaktır. Yöntem: Etik kurul izni alındıktan sonra böbrek transplantasyonu yapılacak 29 hasta çalışmaya alındı. Genel anestezi alan gruba (Grup G, n=15) tiyopental, fentanil ve atrakuryum ile yapılan anestezi indüksiyonunu takiben izofluran, N20 ve 02 verildi. Epidural anestezi uygulanan gruba ise (Grup E, n-14) epidural kateter yerleştirilerek 20 mL %2 prilokain ve 100 g fentanil verildi. İdame amacıyla %1'likprilokain + 2.5 g mL' fentanil (7 mL sa') infüzyonuna başlandı. Her iki gruptan dapreoperatif intraoperatif ve postoperatif 1. ve 3. günlerde kan alınarak tam kan analizi, lökosit subgruplan, CD3, CD16/56, BUN, kreatinin, Na+, K+ düzeyleri çalışıldı. Bulgular: Her iki grupta da demografik özellikler benzerdi. Grup E'de postoperatif 1. gündeki lökosit sayısı Grup G'den anlamlı yüksek, postoperatif 3. günde Hb ve Hct düzeyleri ise anlamlı olarak düşük bulundu. Bu farklar klinik olarak anlamlı değildi. Gruplar arasında CD3, CD16/56, BUN, kreatinin, Na+, K+ düzeylerinde fark bulunmadı. Sonuç: Böbrek transplantasyonu yapılan hastalarda genel ve epidural anestezi uygulamalarının tam kan sayımı, lökosit subgruplan, NK hücre sayısı, BUN, kreatinin, Na+, K+ düzeylerine etkileri benzer bulundu. In chronic renal failure patients whose immunity has been supressed by uremia, the effect of general or epidural anesthesia on the immune system is not well-documented. The aim of our study was to evaluate the effect of general and epidural anesthesia on immunity and complete blood count in patients undergoing renal transplantation. Methods: Following ethics committee approval, 29 patients undergoing renal transplantation were included in the study. After anesthesia induction with thiopental, fentanyl, and atracurium, anesthesia was maintained with isoflurane, N20 and 02 in the general anesthesia group (Group G, n=15). Epidural catheter insertion was followed by injection of 20 mL 2% prilocain and 100 g fentanyl in the epidural anesthesia group (Group E, n-14). 1% prilocain and 2.5 g mL' fentanyl (7 mL hr'1) was infused for maintenance. Complete blood count, leukocyte subgroups, CD3, CD16/56, BUN, creatinine, Na+ and K+ levels were studied on preoperative, intraoperative and on the postoperative 1st and 3rd days in both groups. Results: Demographic data were similar in both groups. In Group E, the leukocyte count on the postoperative 1st day was significantly higher, Hb and Hct levels on the postoperative 3rd day were significantly lower than in Group G. These differences were not important clinically. No significant difference was found for CD3, CD16/56, BUN, creatinine, Na+, and K+ levels between groups. Conclusion: General and epidural anesthesia have similar effects on complete blood count, leukocyte subgroups, NK cell count, BUN, creatinine, Na+ and K+ levels in patients undergoing renal transplantation.
