Radiofrequency thermocoagulation for the treatmentof lower extremity ischemic pain: Comparison of monopolar and bipolar modes

Amaç: Alt ekstremitenin iskemik ağrı tedavisi için radyofrekans termokoagülasyon'un (RFT) güvenle kullanılabileceği bildirilmiştir. Bu çalışmanın amacı alt ekstremitenin iskemik ağrı tedavisi için RFT'un etkinliğini değerlendirmek ve monopolar ve bipolar RFT modlarını karşılaştırmaktı.Gereç ve Yöntem: Etik komite kabulünü takiben alt ekstremite iskemik ağrısı olan, yaşları 18-65 yaş arası, ASA I-III grubu, 30 hasta çalışmaya alındı. Hastalar MRT grubunda (n=15) L düzeyinden 2 dakika monopolar RFT (80°C), BRT grubunda (n=15) ise L2-3 düzeyinden 2 dakika bipolar RFT (80°C) almak üzere rastgele iki gruba ayrıldı. Sistolik ve diastolik kan basınçları, kalp atım hızı, ağrı skorları (NRS) ve ek analjezik ihtiyaçları hastaneden taburcu edildikten 24 saat ve 7, 30 ve 90. günlerde kaydedildi.Bulgular: Her iki grupta NRS skorlarının zaman içerisinde önemli derecede azaldığı ve BRT grubunda MRT grubuna göre 30 ve 90. günlerde istatistiksel olarak önemli derecede daha düşük olduğu tespit edildi (p0.05). İşlem veya tedaviye ilişkin yan etki veya komplikasyon bildirilmedi.Sonuç: Alt ekstremitenin iskemik ağrı tedavisinde hem monopolar hem de bipolar radyofrekans termokoagülasyon tedavi modalitelerinin ağrı düzeylerini önemli derecede azalttığı bulundu. Bununla birlikte, bipolar RFT'un monopolar RFT'a göre 30 ve 90. günlerde daha düşük ağrı skorlarına ve daha uzun analjezi süresine neden olduğu belirlendi

Alt ekstremitenin iskemik ağrı tedavisinde radyofrekans termokoagülasyon:Monopolar ve bipolar modların karşılaştırması

Objectives: Radiofrequency thermocoagulation (RFT) has been reported to be used safely to treat ischemic lower extremity pain. The objective of the present study was to evaluate efficiency of RFT for treatment of lower extremity ischemic pain and to compare effectiveness of monopolar RFT and bipolar RFT modes.Methods: Following ethics committee approval, 30 American Society of Anesthesiologists classification I-III patients with ischemic lower extremity pain aged between 18 and 65 years were recruited. Patients were randomly allocated into 2 groups: MRT group (n=15) received monopolar RFT (80°C) for 2 minutes at L2-3 level, and BRT group (n=15) received bipolar RFT (80°C) for 2 minutes at L2-3 level. Systolic and diastolic blood pressure, heart rate, pain score, and supplemental analgesic requirements were recorded at 24 hours after application and at 7, 30, and 90 days.Results: Numerical rating scale values in both groups decreased significantly over time and it was found to be significantly lower in BRT group after first and third months (p<0.05). Supplemental analgesic requirements were similar with no significant difference between the 2 groups at any point of study period (p>0.05). No adverse event or complication related to procedure or treatment was reported.Conclusion: In patients with ischemic lower extremity pain, both monopolar and bipolar RFT treatment modalities were found to significantly decrease pain levels. However, bipolar mode led to lower pain scores at 30 and 90 days, and longer duration of analgesia than monopolar mode
