    (Springer Wien, 2011) Karaman, Haktan; Kavak, Gonul Olmez; Tufek, Adnan; Celik, Feyzi; Yildirim, Zeynep Baysal; Akdemir, Mehmet Salim; Tokgoz, Orhan
    Background The unavailability of an effective and long-lasting treatment for sacroiliac-based pain has led researchers to study the efficacy of radiofrequency in denervation. In this study, we aimed to investigate the efficacy and safety of novel cooled radiofrequency application for sacral lateral-branch denervation. Methods Patients experiencing chronic sacroiliac pain were selected for our observational study. Fluoroscopy guidance cooled radiofrequency denervation was applied on the L5 dorsal ramus and the S1-3 lateral branches on patients who had twice undergone consecutive joint blockages to confirm the diagnosis and obtained at least 75% pain relief. At the 1st, 3rd and 6th month postoperatively, the patients' pain was evaluated using a visual analog scale (VAS), and their physical function was evaluated with the Oswestry Disability Index (ODI). Results Cooled radiofrequency was applied on a total of 15 patients. Prior to the procedures, the median VAS score (interquartile range) was 8 (7-9), but at the 1st, 3rd and 6th month, this had fallen to 3 (1-4), 2 (1-3) and 3 (2-4). The baseline median ODI score (interquartile range) was 36 (32-38), while at the 1st, 3rd and 6th month, it was 16 (820), 12 (9-18) and 14 (10-20), respectively. At the final control, while 80% of the patients reported at least a 50% decline in pain scores, 86.7% of those reported at least a ten-point reduction in ODI scores. Conclusion It was seen that the cooled radiofrequency used for sacroiliac denervation was an effective and safe method in the short to intermediate term.

    (Int Scientific Information, Inc, 2011) Karaman, Haktan; Tufek, Adnan; Kavak, Gonul Olmez; Yildirim, Zeynep Baysal; Temel, Vildan; Celik, Feyzi; Akdemir, Mehmet Salim
    Background: Over the last several decades there has been a general trend toward reduction and minimalization in surgical treatment of chronic back pain, since open surgery brings complications in small and contained disc herniations instead of achieving expected success. Attention has been focussed on percutaneous nucleoplasty due to the limited success of other minimally invasive methods, as well due to their associated complications. However, there have been few studies in the English literature with a follow-up period of more than I year. Material/Methods: Patients with chronic disc herniations having more significant radicular leg pain, who did not respond to non-invasive treatment methods and for whom open surgery was not an option were selected for percutaneous nucleoplasty application. Upon intervention, patients were prospectively questioned by an independent physician regarding pain, physical improvement, and operation satisfaction at 1, 6, 12 and 24 months. Pain was evaluated with VAS, and physical improvement was evaluated based on the Oswestry Disability Index. Results: Mean VAS that was 8.7 +/- 1.1 before the procedure was determined to be 3.4 +/- 1.9 at 24 months follow-up. At the latest follow-up, 87.5% of the patients reported a 30% or higher decrease in their pain. While Oswestry scores were 76.1 +/- 10.2 in the beginning, they went down to 33.9 +/- 14.9 at the end of 2 years. The percent of those stating good and excellent satisfaction was 66% (23 persons) on the last follow-up. Conclusions: While it is once more shown that nucleoplasty is a safe method, it is also shown that its effectiveness continues at the end of 2 years.

    A Miracle That Accelerates Operating Room Functionality: Sugammadex
    (Hindawi Ltd, 2014) Dogan, Erdal; Akdemir, Mehmet Salim; Guzel, Abdulmenap; Yildirim, Mehmet Besir; Yildirim, Zeynep Baysal; Kuyumcu, Mahir; Gumus, Abdurrahman
    Background. Sugammadex offers a good alternative to the conventional decurarisation process currently performed with cholinesterase inhibitors. Sugammadex, which was developed specifically for the aminosteroid-structured rocuronium and vecuronium neuromuscular blockers, is a modified cyclodextrin made up of 8 glucose monomers arranged in a cylindrical shape. Methods. In this study, the goal was to investigate the efficacy of sugammadex. Sugammadex was used when there was insufficient decurarisation following neostigmine. This study was performed on 14 patients who experienced insufficient decurarisation (TOF < 0.9) with neostigmine after general anaesthesia in the operating rooms of a university and a state hospital between June, 2012, and January, 2014. A dose of 2 mg/kg of sugammadex was administered. Results. Time elapsed until sugammadex administration following neostigmine 37 +/- 6 min, following sugammadex it took 2.1 +/- 0.9 min to reach TOF >= 0.9, and the extubation time was 3.2 +/- 1.4 min. No statistically significant differences were detected in the hemodynamic parameters before and after sugammadex application. From the time of administration of sugammadex to the second postoperative hour, no side effects or complications occurred. None of the patients experienced acute respiratory failure or residual block during this time period. Conclusion. Sugammadex was successfully used to reverse rocuronium-induced neuromuscular block in patients where neostigmine was insufficient.

    Obstetrik hasta grubunda, spinal anestezi altında uygulanan sezaryen operasyonları sonrasında görülebilen post spinal baş ağrısı ile ilişkili faktörler ve insidans
    (2016) Akdemir, Mehmet Salim; Karaman, Haktan
    Sezaryen ile doğum dünyadaki en sık uygulanan obstetrik operasyondur. Sezaryen operasyonlarında rejyonel anestezi yöntemleri sıklıkla tercih edilmektedir. Spinal anestezi, eski ve en etkin rejyonel anestezi tekniklerin biridir. Genel anestezi uygulamalarına göre üstün olduğu durumlar olmasına rağmen bazı komplikasyonları da mevcuttur. Bunlar arasında en sık görülenlerden biriside baş ağrısıdır. Çalışmaya elektif sezaryen endikasyonu konulan, spinal anestezi için kontrendikasyonu bulunmayan, ASA I-II grubuna giren 665 olgu dahil edildi. Olgular rastgele grup I (Atroucan 26 G n=323) ve grup II (Quincke 26 G n=342) olarak iki gruba ayrıldı. Spinal anestezi sonrası; spinal iğne kalınlığı, spinal iğnenin uç şekli kaydedildi. Spinal anestezi uygulayan asistanın eğitim süresi, spinal anestezi için yapılan girişim sayısı, spinal anestezinin yapıldığı aralık (L3–4, L4–5) ve işlem sırasında hastanın sırtını hareket ettirip ettirmediği kaydedildi. Hastanemizde yattığı sürece, 72 saat boyunca baş ağrısı şikâyetleri açısından sorgulandı. İstatistiksel değerlendirmelerde ki-kare ve oranların karşılaştırması (Comparison of proportions) testleri kullanılmış olup P<0,05 değerleri istatistiksel olarak anlamlı kabul edildi. Olguların yaş, boy ve kilo ile baş ağrısı sıklığı arasında anlamlı fark gözlenmedi (P>0,05). Spinal girişim sayısı, girişim aralığı, uygulayıcının tecrübesi, hastanın işlem sırasındaki sırt hareketi, spinal anestezi sonrası hipotansiyon gelişimi, hastaya intraoperatif dönemde verilen mayi miktarı ve gebeliğin tekil veya çoğul olması ile baş ağrısı insidansı arasında istatistiksel olarak anlamlılık bulunmadı (P>0,05). Sonuç olarak 26G kalınlıktaki iki farklı iğne türü arasında baş ağrısı oluşturma insidansı açısından anlamlı bir fark bulunmadı.

    (Kare Publ, 2012) Karaman, Haktan; Kaya, Sedat; Tufek, Adnan; Olmez Kavak, Gonul; Baysal Yildirim, Zeynep; Celik, Feyzi; Akdemir, Mehmet Salim
    Objectives: We aimed to investigate the effectiveness and complications of the percutaneous vertebroplasty (PVP) applications in vertebral compression fractures. Methods: Our study was carried out as a retrospective study in which PVP was conducted on patients with vertebral compression fractures due to benign or malignant causes between October 2006 and December 2009. The patients' pain was evaluated on a visual analog scale ( VAS). In addition, the amount of cement injected, whether or not any leakage from the vertebrae corpus was seen, and any complications resulting from the application during or after the operation were recorded. The age and gender of the patients, duration of pain, number and location of fractured vertebrae, and the duration of follow-up were also collected for evaluation. Results: A total of 15 patients were included in the assessment. Of the patients, 13 were female, and the mean age was 69.5 +/- 8.5 years. A total of 19 PVPs were applied to the 15 patients. While initial VAS scores were 7.9 +/- 1.6, at the end of an average of 10.3 +/- 3.8 ( range: 4-18) months of follow-up, VAS scores had fallen to 2.6 +/- 2.7. 80% of the patients reported at least a 50% reduction in pain scores compared to initial scores, and 86.7% of them reported at least a 2-point decrease in VAS scores. In three patients, leakage of cement into the intervertebral disc occurred. Conclusion: PVP may be used successfully in symptomatic vertebral compression fractures not responding to medical treatment, with a low rate of complications.

    Vertebra kompresyon kırıklarında perkütan vertebroplasti uygulamalarımız
    (2012) Karaman, Haktan; Yıldırım, Zeynep Baysal; Tüfek, Adnan; Çelik, Feyzi; Akdemir, Mehmet Salim; Kavak, Gönül Ölmez; Kaya, Sedat
    Amaç: Vertebra kompresyon kırıklarında perkütan vertebroplasti (PVP) uygulamasının etkinliğini ve komplikasyonlarını araştırmak. Gereç ve Yöntem: Çalışmamız Ekim 2006 ile Aralık 2009 tarihleri arasında benign ya da malign nedenlere bağlı vertebral kompresyon kırığı olan hastalara uygulanmış olan PVP uygulamalarının retrospektif olarak derlenmesi ile yürütüldü. Hastaların ağrıları vizüel analog skala (VAS) ile değerlendirildi. Ayrıca, enjekte edilen sement miktarı, korpus dışına sement kaçışının olup olmadığı, operasyon esnasında veya sonra karşılaşılabilecek komplikasyonlar kayıt altına alındı. Hastaların yaş, cinsiyet, ağrı süresi, kırık vertebra sayısı ve düzeyleri ile uygulama sonrası takip süreleri de değerlendirme için toplandı. Bulgular: Toplam 15 hasta değerlendirilmeye alındı. Hastaların 13 tanesi kadınlardan oluşurken, ortalama yaş 69.5±8.5 yıl idi. On beş hastaya toplam 19 PVP uygulandı. Başlangıç VAS skorları 7.9±1.6 iken, ortalama 10.3±3.8 (aralık: 4-18) aylık takip sonunda 2.6±2.7 düşmüştü. Ağrı skorunda başlangıca göre en az %50 azalma bildiren hasta oranı %80 olarak hesaplanırken, hastaların %86.7si VAS skorlarında en az 2 puanlık azalma bildirmişlerdir. Üç hastada komşu intervertebral diske sement kaçağı gelişti. Sonuç: Medikal tedaviye yanıt vermeyen semptomatik vertebra kompresyon kırıklarında PVP oldukça düşük komplikasyon oranı ile başarıyla uygulanabilmektedir.
