Intra-arterial blood pressure (BP) and heart rate (HR) were continuously recorded in five patients with spinal cord injuries at different levels who were undergoing electro-ejaculation. In three patients with lesions at C7, C5 and T4 insertion of the electrode and electrical stimulation caused severe hypertension and bradycardia. In a patient with a T7/8 lesion and in another with a T10 lesion there were either moderate or minimal cardiovascular changes. Severe hypertension during electro-ejaculation is a serious problem in patients with high lesions and is probably part of the syndrome of autonomic dysreflexia. In the three patients with high spinal cord lesions the procedures were repeated during an intravenous infusion of Prostaglandin E2. Resting BP was lowered and resting HR raised. The level of BP recorded during electrical stimulation was substantially reduced. This enabled larger stimuli to be used for a longer period and resulted in successful ejaculation in two patients.
对五名不同脊髓损伤水平且正在接受电射精治疗的患者，持续记录其动脉内血压（BP）和心率（HR）。三名分别为C7、C5和T4损伤的患者，电极插入和电刺激引发了严重的高血压和心动过缓。一名T7/8损伤患者和另一名T10损伤患者出现了中度或轻度的心血管变化。电射精期间的严重高血压在高位损伤患者中是一个严重问题，可能是自主神经反射异常综合征的一部分。在三名高位脊髓损伤患者中，在静脉输注前列腺素E2期间重复了该操作。静息血压降低，静息心率升高。电刺激期间记录的血压水平大幅降低。这使得能够使用更大的刺激并持续更长时间，两名患者成功射精。
