剖宫产术中出现的一些心电图变化提示心肌缺血。本研究测定了21例硬膜外麻醉剖宫产术中和术后患者血清CK总量和同工酶CK- mb水平。20例患者主诉胸痛、不适和压力，12例患者有ST段压抑。虽然10例患者的总CK活性升高，但所有患者的CK- mb活性均为阴性。心电图变化与剖宫产率相关，发生在外科医生对上腹部和下胸廓施加压力以促进剖宫产时。本研究的数据表明，剖宫产患者尽管主诉胸痛、不适、压力，心电图ST段改变，但通过CK-MB活性测量，未发生心肌损伤。
Some of the changes reported in the ECG of parturients undergoing Caesarean section are suggestive of myocardial ischaemia. This study determined serum CK total and the isoenzyme CK-MB levels in 21 patients during and after Caesarean section under epidural anaesthesia. Twenty patients complained of chest pain, discomfort and pressure, while 12 had ST segmental depression. Although the total CK activity in ten patients was elevated, CK-MB activity in all patients was negative. The electrocardiographic changes were rate-related and occurred at the time pressure was placed upon the upper abdomen and lower thoracic cage by the surgeon to facilitate Caesarean delivery. The data from this study demonstrate that no myocardial injury as measured by CK-MB activity occurs in parturients undergoing Caesarean delivery despite the complaint of chest pain, discomfort and pressure, and ST changes in the ECG.
