Abstract：Objective To observe the ECG changes of acute brain injury patients during surgical general anesthesia and after operation. Methods Twelve-lead ECGs of 186 adult patients were traced during the process of emergency craniocerebral trauma operation and after operation, and ECG monitoring was carried out and recorded. Results Among the 186 cases, there were 157 cases showing various degrees of ECG abnormal changes (accounting for 84.4%), during anesthesia surgery. The ECG abnormalities were commonly sinus bradycardia, ST-T changes, and myocardial ischemia while others mainly included premature beat, arrhythmia, conduction block, abnormal Q waves, and so on. The changes of ECG mainly happened in the acute stage of brain lesions and within one week after craniotomy, and closely related to the severity of the disease. Conclusion Various factors such as cerebral edema, intracranial hypertension, ischemia/ hypoxia and electrolyte imbalance can cause ECG abnormalities among a majority of brain injury patients in acute stage. The changes of ECG were complicated, generally stress response, temporary and reversible, which could be relieved or vanish with the alleviation of the disease. Anesthesia and stimulus of surgical procedures can result in some influences on patients cardiovascular system as well. By monitoring and analysis, potential danger can be identified, and more vigilance is required for patients with structural heart disease.
