氢廓清技术定量测定兔股骨头血流量

QUANTITATIVE MEASUREMENT OF THE FEMORAL HEAD BLOOD FLOW OF THE RABBITS USING HYDROGEN WASHOUT TECHNIQUE

采用氢廓清技术定量测定３０只新西兰兔股骨头血流量，同时监测血压、心率及肛温。结果股骨头血流量为（７．５５±２．７５）ｍＬ·ｇ－１·ｓ－１，血压为（１３±１．４５）ｋＰａ，心率为（２４３±４９）次·ｍｉｎ－１，肛温为（３７．５７±０．４７）℃。表明氢廓清技术是一种简单、可靠、经济的局部骨血流定量测定法，且可用于人体，具有重要临床应用价值。

The hydrogen washout technique was used to measure the femoral head blood flow in thirty New Zealand white rabbits quantitatively and the blood pressure, heart rate and rectal temperature were monitored at the same time. The results showed that the femoral head blood flow was (7.55±2.75)mL·g -1 ·s -1 , the blood pressure was (13±1.45) kPa, the heart rate was (243±49) min -1 , the rectal temperature was (37.57±0 47)℃. We believe that the hydrogen washout technique is a simple, reliable and convenient method for measuring the local bone blood flow quantitatively, and it is valuable clinically in the orthopaedic surgery.
