评价冰片停搏液与犬左膈肌功能受损的关系。用碎冰直接或间接接触膈神经30~60min，可致膈神经瘫痪6~28d，7~62d恢复反应。损伤神经的显微镜检查显示髓鞘损伤和轴突保留。局部心脏低温后左膈肌麻痹可能继发于膈神经冷伤，这是可逆的。
The relationship between ice-chip cardioplegia and impaired left diaphragmatic function was evaluated in dogs. Direct or indirect contact of the phrenic nerve with crushed ice for 30 or 60 minutes resulted in phrenic paralysis for 6 to 28 days, with responsiveness returning from 7 to 62 days later. Microscopical examination of injured nerves revealed injury to the myelin sheath and preservation of axons. Paralysis of the left diaphragm after topical cardiac hypothermia may be secondary to cold injury of the phrenic nerve, which is reversible.
