The frequency of phrenic nerve palsy varies from 2.5 to 8.3%, according to different authors. Contact of the phrenic nerve with cold (ice or saline) seems to be the most frequent etiology. This study points out that good insulation between phrenic nerve and ice slush, used in the pericardium, results in almost complete disappearance of this complication, which is not a benign one, as emphasized by the two deaths in our series.
根据不同作者的研究，膈神经麻痹的发生率在2.5%至8.3%之间。膈神经与寒冷物质（冰或盐水）接触似乎是最常见的病因。本研究指出，在心包中使用时，膈神经与碎冰之间良好的绝缘可使这种并非良性的并发症几乎完全消失，正如我们系列研究中的两例死亡所强调的那样。
