Abstract

Aim: To examine the eff ects of right and left stellate ganglion block (SGB) on blood pressure and the RR, QT, and QTc intervals in patients with primary Raynaud’s phenomenon. Materials and methods: Right and left SGBs were performed with 8 mL of 0.5% bupivacaine in 10 patients with primary Raynaud’s phenomenon. Th ere was an interval of at least 1 week between the right and left blocks of each patient. Th e blood pressure and the RR and QT intervals were measured before the block and 5, 10, 15, 20, and 30 min aft er the block. Th e QTc interval was calculated using Bazett’s formula. Results: Th e RR and QT intervals were longer 20 and 30 min aft er right SGB when compared with the preblock value (P = 0.037 for RR and P = 0.008 for QT). Th e QT and QTc intervals 20 and 30 min aft er left SGB were shorter than the preblock values (P = 0.011, P = 0.012 for QT; P = 0.013, P = 0.009 for QTc). Conclusion: We conclude that right SGB prolongs the RR and QT intervals while left SGB shortens the QT and QTc intervals in patients with primary Raynaud’s phenomenon. Precautions must be taken, taking into account the risk of fatal arrhythmia following right SGB.

Özet

Amaç: Primer Raynaud fenomenli hastalarda bilateral (sağ ve sol) stellat ganglion bloğu (SGB)’nun kan basıncı, RR, QT ve QTc intervali üzerine olan etkisini araştırmak. Yöntem ve gereç: Primer Raynaud fenomenli 10 hastaya 8 mL % 0,5 bupivakain ile sağ ve sol SGB uygulandı. Her hastanın sağ ve sol blokları arasında en az 1 haft a beklenildi. Kan basıncı, RR, QT interval blok öncesi ve blok sonrası 5, 10, 15, 20 ve 30. dakikalarda ölçüldü. QTc intervali ise Bazett’in formülü kullanılarak hesaplandı. Bulgular: Sağ SGB sonrası RR ve QT intervali 20. ve 30. dakikalarda blok öncesi değerlere göre daha uzundu (P = 0,037, P = 0,008 RR ve QT için sırasıyla). Sol SGB sonrası QT ve QTc intervali 20. ve 30. dakikalarda blok öncesi değerlere göre daha kısaydı (P = 0,011, P = 0,012, P = 0,013, P = 0,009 QT ve QTc için sırasıyla). Sonuç: Primer Raynaud fenomenli hastalarda sağ SGB’nin RR ve QT intervalini uzattığı, sol SGB’nin ise QT ve QTc intervalini kısalttığı sonucuna varılmıştır. Özellikle sağ SGB sonrası fatal aritmi gelişebilme ihtimali göz önünde bulundurularak, bu duruma hazırlıklı olunmalıdır.
