Sequential ECP Significantly Increases Carotid and Renal Blood Flow

The purpose of this study was to evaluate the effect of sequential external counterpulsation (SECP) on cerebral and renal blood flow. The effect of SECP on carotid and renal artery blood flow was studied in 35 and 18 patients, respectively. With a portable unit, cuffs were applied to the calves and thighs, sequentially inflated with air at the onset of diastole, and deflated at the onset of systole. Carotid and renal artery Duplex studies were performed during intermittent SECP. Flow velocity and flow velocity integral were measured at baseline and during SECP. Diastolic augmentation of carotid and renal artery flow velocity was observed in all patients. The mean carotid flow velocity integral increased by 22% from 27.7 +/- 1.8 cm to 33.1 +/- 2.3 cm (P = 0.001). The mean renal artery flow velocity integral increased by 19% from 21 +/- 1 cm to 25 +/- 1 cm (P = 0.0001). With SECP, a new diastolic Doppler flow velocity wave was observed, with an average peak carotid diastolic flow velocity of 56 +/- 4 cm/sec and an average peak renal artery diastolic flow velocity of 40 +/- 2.5 cm/sec. This diastolic wave was 75% (carotid) and 68% (renal) as high as the systolic wave during SECP. In addition, with SECP the systolic wave increased by 6% and 8% in the carotid and renal artery, respectively (P = 0.02 and 0.006, respectively). In conclusion, SECP significantly increases carotid and renal blood flow. This noninvasive, harmless treatment may be useful to support patients with decreased cerebral and renal perfusion.

「順序外反搏可增加腦血流量和腎血流」

本研究旨在評估順序體外反搏(SECP)對腦部和 腎臟血流 的影響。研究了SECP對35名患者的頸動脈和18名患者的腎動脈血流的影響。使用便攜式裝置,依次將袖套套在小腿和大腿上,在舒張期開始時充氣;在收縮期開始時放氣。在間歇性SECP期間進行了頸動脈和腎動脈的多普勒超聲檢查。在基線和SECP期間測量了流速和流速積分。所有患者中觀察到頸動脈和腎動脈舒張期流速增加。平均頸動脈流速積分從27.7 +/- 1.8 cm增加了22%,達到33.1 +/- 2.3 cm。平均腎動脈流速積分從21 +/- 1 cm增加了19%,達到25 +/- 1 cm。使用SECP時,觀察到一個新的舒張期多普勒流速波,平均頸動脈舒張期流速峰值為56 +/- 4 cm/sec,平均腎動脈舒張期流速峰值為40 +/- 2.5 cm/sec。在SECP期間,這個舒張期波形高度相對於收縮期波形的比例分別為75%(頸動脈)和68%(腎動脈)。此外,使用SECP時,頸動脈和腎動脈的收縮期波形分別增加了6%和8%。總之,SECP明顯增加了頸動脈和 腎臟血流 。這種無創、無害的治療方法可能對腦部和腎臟灌注減少的患者有用。
