One hundred and eighty-one bleeding episodes involving two sites simultaneously were noted during a survey of 4935 bleeding episodes, an incidence of 3.7%. Elbows, knees and ankles were the commonest sites involved in double bleeds, while the thigh, upper arm and elbow were the commonest sites involved in the double bleeds needing most transfusions. The overall transfusion requirements were less than for single bleeds. The frequency of multiple bleeds correlated significantly with the overall bleeding frequency, but not with the number of days under observation.
在对4935次出血事件的调查中，发现有181次出血事件同时涉及两个部位，发生率为3.7%。双部位出血最常累及的部位是肘部、膝盖和脚踝，而需要最多输血的双部位出血最常累及的部位是大腿、上臂和肘部。总体输血需求量低于单部位出血。多部位出血的频率与总体出血频率显著相关，但与观察天数无关。
