ABSTRACT

Objective:To investigate the experience of moderate hypothermia(28℃) using in Stanford A aortic dissection.Methods:A retrospective analysis of 100 patients with Stanford A aortic dissection from January 2012 to March 2014, including 50 cases with deep(25℃) hypothermic circulatory surgery and 50 moderate(28℃) hypothermic circulatory surgery. The operation was performed with ascending aortic replacement, inclusiong aortic arch angioplasty, and stent implantation with descending aorta stent. The difference between the 2 groups during and after the operation was compared.Results:2 cases died in the hypothermia group, and 3 cases died in the deep hypothermia group. There were significant differences( P<0.05) between the middle and low temperature groups in the cooling time, the time of stopping circulation, the time of rewarming, the time of cardiopulmonary bypass, the time of operation, the time of operation, the time of conscious, the time of mechanical ventilation and the first day after the operation( P<0.05), but there was no significant difference between the creatinine and the bilirubin( P>0.05). Conclusion:Under the condition of sufficient cerebral perfusion and spinal cord protection, moderate hypothermia is safe, and it can reduce the operation time and postoperative complications. It has certain clinical significance.

ABSTRACT

The incidence of dextrocardia is lower. The dextrocardia is often associated with congenital anatomical abnormalities. The patient with normal cardiac structure of dextrocardia and severe coronary heart disease that needs coronary artery bypasss is rarer. This article summarizes the perioperative management and surgical experience of dextrocardia with bypass surgery via a clinical case.

ABSTRACT

Objective To investigate the effect of different doses of protamine neutralizing heparin on perioperation of on-pump coronary artery bypass graftting (CABG).Methods A total of 180 on-pump CABG patients hospitalized from January 2015 to November 2016 were randomly divided into three groups,the protamine group l,protamine group 2 and protamine group 3,60 patients in each group.Heparin (3 mg/kg) was used before extracorporeal circulation.After intracardiac operation was over,protamine was used to neutralize the heparin to adjust the activated clotting time (ACT) in protamine group 1,which was 10% higher than that of intubation.Meanwhile,protamine group 2 was neutralized to equal to the ACT before intubation,and protamine group 3 was 10% lower than that before the intubation.The differences of intraoperative and postoperative parameters were compared between the three groups.Results No death was found in the three groups during hospitalization.Comparing with protamine group 1 and protamine group 2,the time of operation,the ACT before the leaving operation room,the ACT of the first hour after returning to ICU,the amount of bleeding during operation,the time of closing and the amount of red blood for transfusion were decreased in protamine group 3 (P > 0.05).The total amount of protamine for neutralizing and the ratio of protamine and heparin were significantly increased in protamine group 3 (P < 0.05).The heart dysfunction after operation,perioperative myocardial infarction,pulmonary edema,pulmonary infection,renal dysfunction,poor wound healing,neurological complications,and time of in hospital stay showed no significant differences between three groups (P>0.05).Conclusion ACT below 10% of preoperation is safe,after neutralization of heparin by protamine,which can obviously reduce the bleeding,the time of sternal closure and the amount of red blood cell transfusion,showing a positive clinical significance.

ABSTRACT

Objective To summarize the experience of surgical treatment in patients with uremia and severe coronary artery disease, and reduce the perioperative risk thereof. Methods Sixteen chronic renal failure patients who were received haemodialysis and underwent coronary artery bypass grafting (CABG) during the period of February 2009 to December 2016 in Tianjin First Central Hospital were assessed in this retrospective study. Of the 16 patients, 8 patients and 6 patients were treated with off pump and on pump CABG respectively, one patient was treated with CABG and resection of ventricular aneurysm, and one patient was treated with CABG and tricuspid valve replacements. The renal function changes in preoperative and postoperative periods, 2-day and 1-week after surgery were observed. Echocardiography was used to evaluate cardiac function. The improvement of angina was recorded. Results Fourteen patients were successfully withdrawn from ventilator therapy within 24 h after surgery. The tracheal intubation was removed 65-hour after surgery in one patient. One patient died of multiple organ failure on the seventh day after surgery. The average length of ICU staying and in-hospital stay were (125.5 ± 21.6) h and (28.6 ± 7.4) days respectively. The serum creatinine (sCr) and blood urea nitrogen (BUN) were higher in two days after surgery than those before the operation (P 0.40, and no angina occurred. Conclusion CABG is relatively safe for patients with end-stage renal disease and severe coronary artery disease. CABG can significantly eliminate angina symptoms with satisfactory clinical effect.
