Introduction: The goal of this study was to compare the effects of low-flow desflurane anesthesia and high-flow anesthesia on consumption of anesthetic agent, hemodynamic parameters, respiratory parameters and postoperative recovery profiles.

Materials and methods: Following ethics committee approval, 60 ASA I - II patients, who were 18-65 y and to undergo elective tympanoplasty surgery by the same surgeon were included in this prospective, randomized, double blind clinical trial. At the preoperative visit, details of the anesthetic technique and the study protocol were fully explained, and written consent was obtained from each patient prior to the study. Before each surgery, anesthesia circuits leakage control and calibration of gas monitors were performed. Single-use anesthesia circuit was used for each patient and bacteria filter was applied routinely. CO2 absorbent was changed for each patient. All patients were premedicated and in the operating room an IV catheter was inserted and standard monitors were applied (GE Datex-Ohmeda S/5™ Anesthesia Monitor, Helsinki, Finland). For induction of anesthesia, 1 mg / kg lidocaine (Aritmal ®% 2), 2 mg / kg propofol (Diprivan ®), 0.125 mcg/kg/min remifentanil (Ultiva®) infusion, and 0.6 mg / kg rocuronium bromide (Esmeron®) were administered intravenously. All cases were mechanically ventilated with a tidal volume of 8-10 ml/kg and the ventilatory rate of 12/dk with ADU (Datex-Ohmeda® S / 5 Anesthesia) anesthesia device in all cases, the gas analyzer was connected to the monitor. To provide denitrogenation rapidly fresh gas flow of 6 L/ min (O2/Air = 2/4) in the form of 4-6% desflurane was adjusted the first 10 min after induction of anesthesia. After tenth minutes, the patients were divided randomly into two equal groups. Anesthesia was continued with desflurane 2 % in 66 % air with oxygen with a fresh gas flow of 6 L/ min in the first group (Group-Y (n = 30)), and in the second group(Group-D (n = 30)) a fresh gas flow of 1 L/ min were adjusted.

Results: Sixty patients were enrolled in this study with 30 patients in each group; the groups were similar with respect to age, weight, height, ASA physical status, and duration of surgery and anesthesia. There were no significant differences among the groups in terms of ETCO2, inspired CO2 and COHb levels. In the low-flow group, total consumption of desflurane were 52% less than the control group. We found that the circuit heat and humidity has higher values in the low flow group according to the control group.

Conclusion: We didn’t find significant clinical differences between the two methods in terms of oxygenation, hemodynamic parameters, ETCO2, arterial blood gas values. In cases of tympanoplasty, we can say that administration of low flow desflurane anesthesia is safe with systems providing monitorization of inspired and expired gas.

Giriş: Çalışmamızda, timpanoplasti operasyonlarında düşük akımlı desfluran anestezisi ile yüksek akımlı yöntemi karşılaştırarak anestezik ajan tüketimi, hemodinami, solunumsal parametreler ve postoperatif derlenmeye etkilerini değerlendirmeyi amaçladık.

Materyal Metod: Çalışmamızda etik kurul izni alındıktan sonra 18-65 yaş arası elektif koşullarda timpanoplasti operasyonu planlanan ASA l-ll risk grubundaki toplam 60 gönüllü hasta yer aldı. Hastalar ameliyat öncesi dönemde uygulanacak olan anestezi tipi hakkında bilgilendirilerek, onlara işleme ve çalışmaya dair izin formları imzalatıldı. Her operasyondan önce, anestezi devrelerinin kaçak kontrolü ve gaz monitörlerinin kalibrasyonu yapıldı. Rutin uyguladığımız şekilde, her olgu için tek kullanımlık anestezi devresi ve bakteri filtresi kullanıldı. Her hastada CO2 absorbanı değiştirildi. Tüm olgulara operasyondan önce pre-medikasyon yapıldı. Hastalara standart monitorizasyon uygulandı. Anestezi indüksiyonu için 1 mg/kg lidokain (Aritmal® % 2), 2 mg/kg propofol (Diprivan®), 0.125 mcg/kg/dk Remifentanil (Ultiva®) infüzyonu, ve 0.6 mg/kg rokuronyum bromür (Esmeron®) iv uygulanarak BİS değeri 40-60 arasında olduğunda laringoskop ile entübasyon yapıldı. Endotrakeal entübasyondan sonra tüm olgular ADU (Datex-Ohmeda® S/5 Anesthesia) anestezi cihazında tidal volüm 8-10 ml/kg ve solunum sayısı 12 /dk olacak şekilde % 50 O2 - % 50 hava ile solutulmaya başlandı. Taze gaz akımı denitrojenizasyonunu sağlamak ve anesteziyi hızla derinleştirmek amacıyla, anestezi indüksiyonu sonrası ilk 10 dk. için, 6 It/dk (O2/Hava=2/4) içinde % 4-6 desfluran şeklinde ayarlandı. Hastaların tamamına remifentanil (Ultiva®) 0.125 mcg/kg/dk dozunda infüzyonu yapıldı. Birinci grup hastaya (Grup-Y (n=30)), anestezi uygulamasının devamı için; % 33 O2 ve % 66 hava karışımı içinde % 4-6 desfluran ile taze gaz akımı 6 İt /dk (O2/Hava=2/4) olacak şekilde devam edilirken, ikinci grup hastada (Grup-D (n=30)) ise 10. dk.’dan sonra akım hızı FiO2 değeri %30’un üzerinde olacak şekilde 1 It/dk’ya (O2/ Hava=0.5/0.5) indirildi ve % 4-6 desfluran uygulandı.

Bulgular: . Gruplardaki olgular arasında sosyo demografik özellikler açısından istatistiksel olarak anlamlı fark yoktur. Her iki grup arasında inspire edilen CO2, ETCO2 ve COHb düzeyleri açısından fark bulunmamıştır. Desfluranın toplam tüketimi düşük akımlı grupta kontrol grubuna göre %52 az bulunmuştur. İki grup arasında yaptığımız karşılaştırmada düşük akım grubunda düşük akımın başlangıcından itibaren kontrol grubuna göre devre ısı ve nem değerlerinin yüksek olduğunu bulduk.

Sonuç: Sonuç olarak bu çalışmada ASA l-ll grubunda timpanoplasti operasyonu geçiren hastalarda düşük akım ve yüksek akımlı desfluran anestezisinin bulgularını değerlendirdik. İki yöntem arasında oksijenasyon, hemodinamik parametreler, ETCO2, kan gazı değerleri açısından klinik olarak anlamlı farklılık bulamadık. Timpanoplasti vakalarında inspire ve ekspire edilen gaz monitörizasyonu sağlayan sistemlerle düşük akımlı desfluran anestezi uygulamasının güvenli olduğunu söyleyebiliriz.
