Fifty-two patients were randomized into two groups of 26 to the use of either 5 or 7/8F catheters for their first left heart cardiac catheterization. Clinical characteristics for the two groups were similar. 5F catheters were significantly inferior to 7/8F catheters in terms of torque control (P less than .001), ease of engaging coronary ostia (P less than .001), and quality of angiograms (P less than .05). Nine patients in the 5F group required a change to 7/8F catheters for completion of the procedure. There was no difference in procedure time or fluoroscopy time between the groups. Time to haemostasis was significantly shorter in the 5F group (P less than .01), but there was no difference between groups with respect to haematoma formation or rebleed after haemostasis. We conclude the slight advantage of 5F catheters in terms of haemostasis is outweighed by many disadvantages. Their routine use in cardiac catheterization, at least at this time, cannot be recommended.
52例患者被随机分为两组，每组26例，在首次左心导管插入术中分别使用5F或7/8F导管。两组的临床特征相似。在扭矩控制方面（P<0.001）、进入冠状动脉口的难易程度方面（P<0.001）以及血管造影质量方面（P<0.05），5F导管明显逊于7/8F导管。5F组中有9例患者需要更换为7/8F导管才能完成手术。两组之间的手术时间或透视时间没有差异。5F组的止血时间明显更短（P<0.01），但在血肿形成或止血后再出血方面，两组之间没有差异。我们得出结论，5F导管在止血方面的轻微优势被许多劣势所抵消。至少在目前，不建议在心脏导管插入术中常规使用它们。
