一位１９岁女孩夜间煤气中毒深昏迷，经抢救一天内神志恢复，第７天右下肢感觉由消失到恢复，肌力由Ⅰ级增加到Ⅳ级。但右下肢腓总神经损伤的典型表现两年后才逐渐恢复。可见一氧化碳中毒产生的周围神经损害比中枢神经损害的恢复时间慢得多。 A 19-year-old girl was deeply comatose at night with gas poisoning. After rescuing one day of recovery, her right lower extremity recovered from disappearance to recovery on the 7th day. Muscle strength increased from Grade I to Grade IV. However, the typical manifestation of the common peroneal nerve injury in the right lower limb gradually recovered after two years. It can be seen that peripheral nerve damage caused by carbon monoxide poisoning is much slower than recovery time of central nervous system damage.
