Esophageal and cardiac arrhythmia after surgery

By | March 21, 2012

Esophageal and cardiac arrhythmias after surgery was 13% _36.5%, some scholars reported that more than 50%. To sinus tachycardia, followed by a supraventricular tachycardia and ventricular arrhythmia, is a common complication of esophageal cancer surgery. To discover and correct the arrhythmia, to reduce the postoperative mortality rate has an important role.
Esophageal and cardiac arrhythmia after surgery for many reasons, and affect each other. Surgical stress and trauma are the most common cause. Reported in the literature, due to surgical trauma, pain, cardiac arrhythmia caused 43.5% of the total arrhythmia around, almost all sinus tachycardia, no special treatment, 48h in self-healing. Arrhythmia and postoperative hypoxemia is another important factor. Myocardial sensitivity to hypoxia, the earliest changes in the pathophysiology of heart rate to compensate hypoxia. Hypoxemia caused by reasons: thoracotomy PaOz decreased to the lowest postoperative 1_2 days, began to rise on day 3; low vital capacity before surgery and preoperative combined heart and lung disease, hypertension, diabetes higher incidence of postoperative arrhythmia; postoperative pleural effusion, pleural product gas, pneumonia, atelectasis, sputum block, pulmonary edema, chest gastric dilatation, ARDS and so enable the pulmonary ventilation / perfusion imbalance and increased postoperative hypoxemia; preoperative radiotherapy in patients with a higher incidence of postoperative arrhythmia, long duration, degree of weight than other types of arrhythmias, and easier to pulmonary complications.
Anastomosis above the aortic arch surgery of esophageal cancer after operation significantly increased the incidence of arrhythmia, its causes are unknown. Eating poor preoperative and postoperative electrolyte imbalance and acid-base balance is an important cause of postoperative arrhythmia, when the serum bait below 3.5mmol / L, the higher the incidence of arrhythmia.
Of the food pipe cancer and the prevention of cardiac arrhythmia after surgery should be for different reasons to take appropriate measures, preoperative correction of water, electrolyte, acid-base balance, improve the nutritional status, abnormal electrocardiogram should attach great importance to active treatment. Preoperative respiratory illness, respiratory preoperative preparation should be strengthened to improve lung function. Action should be gentle surgery operations to minimize the lung tissue, stretch and squeeze the heart. Net absorption of surgery sputum, full expansion of lung is very important. After close monitoring, regular oxygen, continuous and reliable for gastrointestinal decompression and closed thoracic drainage, assist in expectoration, ensure airway patency, to detect and deal with other complications of heart and lung function.
