随着世界现代医药学和我国传统医药学的深入发展,中药和西药的在临床上的联合应用非常普遍。而目前在临床中西药合用过程中往往只注重中西药合用的有效性,却忽视了因配伍禁忌而可能出现疗效降低、产生或增加毒副作用的不合理用药。这不仅造成资源的浪费,同时也增加药源性疾病的发生。这应引起广大医药工作者及患者的高度重视。笔者参考近年来有关文献资料,就临床中西药合用的配伍禁忌问题进行归纳论述。
Objective To establish a method for quality control of Astragalus Radix and Scutellariae Radix in Biqiaotong granules and provide basis for the establishment of quality standard. Methods The single-factor test method was used to investigate the factors of thin layer chromatography (TLC) conditions, including different extract method and solvents, developing system, comogemc agents, temperature, humidity, drawing amounts and thin layer boards, and to screen the best TLC conditions of Astragalus Radix and Scutellariae Radix . Results The TLC conditions of Astragalus Radix were used trichloromethane-methanel-water (13:7:2) as developing solvent, separated on silica gel G, heatd under 105℃ until the spots bacame clear. The TLC conditions of Scutellariae Radix were used methylbenzene-ethy acetate- formic acid-methanel (9:3:2:2) as developing solvent, separated on silica gel G, observed after 30 minutes under daylight until the spots were clear. Conclusions The spot features are clear, and with good separating degree, strong specificity, and good repeatability without the inference of negative control. The TLC method is simple, sensitive and accurate, which can be adopted for the quality control of Biqiaotong granules.
The surgical treatment of thoraco-abdominal aortic aneurysm is a unique solution completed by multidisciplinary cooperation. Preoperative detailed examination and evaluation should be carried out to determine the appropriate point for surgery and optimize the organ function through necessary means. During perioperative period, excellent surgical skills and appropriate strategy of extracorporeal circulation will be adopted according to the scope of involvement, and necessary measures will be utilized to monitor and protect the functions of vital organs. Close monitoring and management in postoperative stage, early warning of complications and effective treatment are essential ways to improve the prognosis of TAAA surgery. This article reviews the research progress in perioperative management of TAAA surgery.
ObjectiveTo explore and analyze the risk factors for arrhythmia in patients after heart valve replacement.MethodsA retrospective analysis of 213 patients undergoing cardiac valve replacement surgery under cardiopulmonary bypass in our hospital from August 2017 to August 2019 was performed, including 97 males and 116 females, with an average age of 53.4±10.5 year and cardiac function classification (NYHA) grade of Ⅱ-Ⅳ. According to the occurrence of postoperative arrhythmia, the patients were divided into a non-postoperative arrhythmia group and a postoperative arrhythmia group. The clinical data of the two groups were compared, and the influencing factors for arrhythmia after heart valve replacement were analyzed by logistic regression analysis.ResultsThere were 96 (45%) patients with new arrhythmia after heart valve replacement surgery, and the most common type of arrhythmia was atrial fibrillation (45 patients, 18.44%). Preoperative arrhythmia rate, atrial fibrillation operation rate, postoperative minimum blood potassium value, blood magnesium value in the postoperative arrhythmia group were significantly lower than those in the non-postoperative arrhythmia group (P<0.05); hypoxemia incidence, hyperglycemia incidence, acidosis incidence, fever incidence probability were significantly higher than those in the non-postoperative arrhythmia group (P<0.05). The independent risk factors for postoperative arrhythmia were the lowest postoperative serum potassium value (OR=0.305, 95%CI 0.114-0.817), serum magnesium value (OR=0.021, 95%CI 0.002-0.218), and hypoxemia (OR=2.490, 95%CI 1.045-5.930).ConclusionTaking precautions before surgery, improving hypoxemia after surgery, maintaining electrolyte balance and acid-base balance, monitoring blood sugar, detecting arrhythmia as soon as possible and dealing with it in time can shorten the ICU stay time, reduce the occurrence of complications, and improve the prognosis of patients.
Objective To investigate the risk factors for arrhythmia after robotic cardiac surgery. Methods The data of the patients who underwent robotic cardiac surgery under cardiopulmonary bypass (CPB) from July 2016 to June 2022 in Daping Hospital of Army Medical University were retrospectively analyzed. According to whether arrhythmia occurred after operation, the patients were divided into an arrhythmia group and a non-arrhythmia group. Univariate analysis and multivariate logistic analysis were used to screen the risk factors for arrhythmia after robotic cardiac surgery. ResultsA total of 146 patients were enrolled, including 55 males and 91 females, with an average age of 43.03±13.11 years. There were 23 patients in the arrhythmia group and 123 patients in the non-arrhythmia group. One (0.49%) patient died in the hospital. Univariate analysis suggested that age, body weight, body mass index (BMI), diabetes, New York Heart Association (NYHA) classification, left atrial anteroposterior diameter, left ventricular anteroposterior diameter, right ventricular anteroposterior diameter, total bilirubin, direct bilirubin, uric acid, red blood cell width, operation time, CPB time, aortic cross-clamping time, and operation type were associated with postoperative arrhythmia (P<0.05). Multivariate binary logistic regression analysis suggested that direct bilirubin (OR=1.334, 95%CI 1.003-1.774, P=0.048) and aortic cross-clamping time (OR=1.018, 95%CI 1.005-1.031, P=0.008) were independent risk factors for arrhythmia after robotic cardiac surgery. In the arrhythmia group, postoperative tracheal intubation time (P<0.001), intensive care unit stay (P<0.001) and postoperative hospital stay (P<0.001) were significantly prolonged, and postoperative high-dose blood transfusion events were significantly increased (P=0.002). Conclusion Preoperative direct bilirubin level and aortic cross-clamping time are independent risk factors for arrhythmia after robotic cardiac surgery. Postoperative tracheal intubation time, intensive care unit stay, and postoperative hospital stay are significantly prolonged in patients with postoperative arrhythmia, and postoperative high-dose blood transfusion events are significantly increased.
