Abstract

Objective: Ischemia and reperfusion injury due to tourniquet application during arthroscopy is a well known problem. This study aimed to compare the eff ects of dexmedetomidine and ketamine on hemodynamic and respiratory variables and on total anti-oxidant status (TAS), total oxidant status (TOS) and malondialdehyde (MDA) as markers of ischemia-reperfusion injury.Materials and Methods: This study was approved by a local ethics committee. The study was performed on patients undergoing arthroscopic operation under spinal anesthesia. Thirty patients were randomized into two groups: Group D (dexmedetomidine; n=15) and Group K (Ketamine; n=15). Spinal anesthesia at the L2-4 level was achieved using a 25G spinal needle with hyperbaric bupivacaine at a dose of 12-15 mg in all patients. In Group D, patients were sedated with dexmedetomidine at a dose of 0.3-0.5 μg/kg/h, while Group K received ketamine at a dose of 1-1.5 mg/kg/h. Hemodynamic parameters, oxygen saturation, Ramsey sedation scale (RSS), and TAS, TOS, and MDA levels were recorded.Results: Demographic parameters, TAS, TOS and MDA levels were similar between groups. In Group K, the TOS levels after tourniquet removal were significantly lower than at baseline and during the use of the tourniquet. Preoperative hemodynamic and respiratory variables were similar in both groups. Blood pressure values were decreased compared to baseline but these decreases were not statistically significant.Conclusion: In patients undergoing arthroscopy under spinal anesthesia, dexmedetomidine had eff ects similar to ketamine, led to insignificant alterations in hemodynamic and respiratory variables during surgery and had comparable eff ects on ischemia-reperfusion injury. Thus, we think that dexmedetomidine can be a safe alternative to ketamine as an intraoperative sedative.

Özet

Amaç: Artroskopi esnasında uygulanan turnike sonrası iskemi reperfüzyon hasarı geliştiği bilinmektedir. Bu çalışmada sedatif-anksiyolitik amaçla kullanılan dexmedetomidin ve ketamin’in hemodinamik, respiratuar değerler ve iskemi-reperfüzyon hasarını ve oksidatif stres yanıtını gösteren total anti-oksidan status (TAS), total oksidan status (TOS) ve malondialdehit (MDA) ile karşılaştırılmaları planlandı.Gereç ve Yöntem: Hastane yerel etik kuruldan onay alındıktan sonra artroskopi uygulanacak hastalar rasgele iki gruba ayrıldılar. Grup D (Dexmedetomidin; n=15) ve Grup K (Ketamin; n=15) olarak iki grup belirlendi. Hastalara L2-4 seviyesinden 25G spinal iğne ile hiperbarik bupivakain (12-15 mg) kullanarak spinal anestezi sağlandıktan sonra sedatif anksiyolitik amaçla Grup D’de dexmedetomidin (0.3-0.5 μgr/ kg/saat), Grup K’de ketamin 1-1.5 mg/kg/saat infüzyon olarak verildi. İntraoperatif hemodinamik değerler, Ramsey sedasyon skalası (RSS), SpO2 ve TAS, TOS ve MDA düzeyine bakıldı.Bulgular: Demografik veriler ve TAS, TOS ve MDA değerleri her iki grupta benzerdi. Ketamin verilen grupta grup içi değerlendirmede turnike sonrası TOS değerleri giriş ve turnike sırasındaki değerlerden anlamlı olarak düşük bulundu. Peroperatif olarak hemodinamik ve respiratuar parametrelerde gruplar arası fark yoktu. Her iki grupta da kan basınçlarında başlangıç değerlerine göre azalma oldu, ancak bu istatistiksel olarak anlamlı değildi.Sonuç: Spinal anestezi altında turnike uygulanan artroskopi hastalarında sedatif olarak dexmedetomidin uygulanmasının ketaminle benzer hemodinamik ve respiratuar ve iskemi-reperfüzyon değerleri gösterdiği ve ketamine güvenli alternatif olabileceği sonucuna varılmıştır.
