| 摘 要： | 目的探讨甲醛对一氧化碳中毒血的检测是否产生干扰,提高一氧化碳中毒鉴定的可靠性。方法采用常用的血中一氧化碳或碳氧血红蛋白饱和度的检测方法对未加甲醛和加甲醛的血样分别进行实验研究。结果甲醛对加热法、氢氧化钠法、氯化钯法、分光光度法等检测方法均可产生不同程度的干扰。结论经福尔马林灌注或固定的检材不宜用于一氧化碳中毒血检测,否则可能导致错误的鉴定结论。

| Abstract: | Objective To confirm whether formaldehyde disturb detecting carbon monoxide in blood.To give an evidence that can be used for detecting carboxyhemoglobin more accurately in carbon monoxide poisoning ap-praises.Methods Blood samples came from carbon monoxide poisoning and the health were collected.Regular methods for detecting carboxyhemoglobin were used.Observing and comparing the detection results between which were spiked with methanal and no spiked one were performed.Results Methanal will affect the result of following experiments such as heating,adding NaOH,absorbed by PdCl 2 and spectrophotometry.Conclusion The samples which contaminated by formaldehyde couldn't be used for detecting carboxyhemoglobin. |
