  • Clinical Analysis of Minimal Incision for Total Hip Arthroplasty

    摘要:目的:探讨小切口全髋关节置换的疗效及优缺点。方法:针对性选取我院行THA的病员48例,分为初期小切口THA组、熟练小切口THA组、传统切口THA组,各组16例。记录切口长度、术中出血量、术后12小时引流量、手术时间及Harris评分,对其治疗效果进行回顾性分析。结果:初期小切口THA组平均出血量,术后12小时平均引流量,平均手术时间等指标均高于传统组,术后Harris评分低于传统组,熟练组与传统组比较,切口长度较短、术中出血量略少,术后早期Harris评分高,远期Harris评分接近。结论:熟练小切口THA与传统切口THA比较远期疗效无明显优点,初期小切口THA不具微创优势,不必强求小切口THA,并应注重学习曲线。

  • Insights into the clinical studies related to cardiovascular surgery from the American Heart Association’s Scientific Sessions 2021: Part one

    In the American Heart Association’s Scientific Sessions 2021, the results of six clinical trials related to cardiovascular surgery were revealed. The PALACS trial demonstrated that posterior left pericardiotomy during open heart surgery was associated with a significant reduction in postoperative atrial fibrillation; the EPICCURE study found that injection of mRNA encoding vascular endothelial growth factor (VEGF-A mRNA) directly into the myocardium of patients undergoing elective coronary artery bypass grafting (CABG) improved patients’ heart function; the VEST trial once again proved the safety and potential value of external stent for vein graft. This article will interpret the above-mentioned three studies.

  • Concurrent surgical left atrial appendage occlusion should become routine procedure in cardiac surgery for atrial fibrillation patients — Commentary on LAAOS Ⅲ

    Left atrial appendage occlusion is a common procedure for patients with atrial fibrillation history when they underwent cardiac surgery. Before the LAAOS Ⅲ research results, this operation has been lacking strong evidence-based support. LAAOS Ⅲ is a prospective, double-blind, international multicenter, randomized blinded trial. According to the results of LAAOS Ⅲ, the left atrial appendage occlusion can reduce the risk of stroke and systemic embolism. This article will perform detailed interpretation of LAAOS Ⅲ research.

  • Interpretation of methodological standards for the design, implementation, and analysis of randomized trials in cardiac surgery: A scientific statement from the American Heart Association in 2022

    Cardiac surgery presents specific challenges in conducting randomized controlled trials (RCTs). The American Heart Association made a scientific statement of methodological standards, with the purpose to review key concepts and standards in design, implementation, and analysis of cardiac surgery RCTs, and to provide recommendations. Recommendations include an evaluation of the suitability of the research question, clinical equipoise, feasibility of enrolling a representative patient cohort, impact of practice variations on the effect of the study intervention, likelihood and impact of crossover, and duration of follow-up. Trial interventions and study end points should be predefined, and adequate deliverability of the trial interventions should be ensured. Every effort must be made to keep a high completeness of follow-up. Trial design and analytic techniques must be tailored to the specific research question and trial setting. In this paper, the authors made an interpretation of this scientific statement based on their practical experience.

  • Research on Visualization of Ultrasonic Rhinitis Therapeutic Apparatus Based on V4L2

    This paper reports the study and design of a visualization system of the ultrasonic rhinitis therapeutic apparatus with the function of endoscopic sinus. On Linux operating platform, we captured the video data of a video capture card that connected the endoscopic sinus using Video4Linux (V4L2) that was provided by the operating system. The video images were displayed by Qt. The visualization system solved the problem that the current ultrasonic rhinitis therapeutic apparatus had to rely on the large and expensive endoscopy equipment. And this simplified the doctors' operation, met the need of monitoring nasal cavity in the process of operating, greatly reduced the costs of treatment and would contribute to the promotion of the instrument. As a result, it has been tested that the nasal endoscopic image achieved by the system is clear and smooth, and fully meet the clinical needs of ultrasonic treatment of rhinitis.

  • Protective Effect of Non-peptide Endothelin Antagonist Ferulic Acid on Lung Injury During Cardiopulmonary Bypass.

    Objective To investigate the role of endothelin(ET) in lung injury during cardiopulmonary bypass (CPB) and study the possible mechanism of ET-mediated lung injury and the protective effect of ferulic acid(FA) during the procedure. Methods Twelve dogs were randomly divided into 2 groups and models of CPB with pulmonary perfusion were established by perfusion of 4 C FA solution through proximal pulmonary artery in the experiment group while control group only received 4 C crystal cardiac arrest solution without pulmonary perfusion. Changes in the content of ET, NO, malonaldehyde (MDA), dry to wet (D/W) in lung tissue and lung function- related indices PaO2/FiO2, airway pressure (AWP), pulmonary vascular resistance (PVR), lung compliance before and after CPB in both groups were measured respectively. Results ET content increased after CPB in control group (P〈0. 05) ,while experiment group had a lower level of ET than that of control group (P〈0.05); D/W, MDA levels in experiment group decreased (P〈0. 05), but NO content increased (P〈0. 05) as compared with control group. After pulmonary perfusion with FA, PaO2/FiO2 and lung compliance values in experiment group were higher than those of control group (P〈0.05),AWP, PVR values lowered accordingly(P〈0. 05). Lung injury was less severe in the experiment group. Conclusion ET is involved in pathogenesis of lung injury during CPB, FA can effectively reduce lung injury and improve lung function thus having a good protective effect on the lung.

  • Situation of portal vein thrombosis and related coagulation function indicators analysis after splenectomy due to different etiologies

    ObjectiveTo analyze the platelet (PLT) count, coagulation function, and portal vein thrombosis (PVT) in the patients underwent splenectomy due to different etiologies. MethodsThe patients who underwent splenectomy in the Affiliated Hospital of Southwest Medical University from January 2013 to December 2022 were collected. According to the etiology, the patients were assigned into the occupying group (splenic and pancreatic occupying lesions), hypersplenism group (portal hypertension and hypersplenism), and splenic rupture group (traumatic splenic rupture). The changes of PLT, white blood cells (WBC), red blood cells (RBC), neutrophils (Neut), prothrombin time (PT), activated partial thromboplastin time (APTT), fibrinogen (Fib), D-dimer (DD), and PVT were observed after splenectomy. ResultsA total of 166 patients were collected, including 42 in the occupying group, 22 in the hypersplenism group, and 102 in the splenic rupture group. There were no statistically significant differences in the age and preoperative Child-Pugh score among the patients of the three groups (P>0.05). There were 12 (7.2%) patients with PVT, including 2 in the occupying group, 6 in the hypersplenismn group, and 4 in the splenic rupture group. The PVT incidence among the three groups had a statistical significant difference (Fisher exact test, P=0.003), which in the hypersplenismn group was higher than the occupying group (P=0.016) and the splenic rupture group (P=0.002), while there was no statistically significant difference between the occupying group and the splenic rupture group (P=1.000). The overall trend was that the PLT, RBC, WBC, and various coagulation function indicators such as PT, APTT, and Fib among the three groups all showed an upward trend immediately after splenectomy, but the postoperative peak time and change trends had no markedly regular among the three groups. The PLT of the patients with and without PVT changed over time during the observation period (patients without PVT: F=60.238, P<0.001; patients with PVT group: F=9.700, P=0.043), and which showed a continuous upward trend after surgery, reaching a peak on the 14th day and then beginning to decline in the patients of both 2 groups. However, there was no statistically significant intergroup effect between the 2 groups (F=0.056, P=0.816). ConclusionsThe results of this study suggest that the peak value of PLT in the hypersplenism group is lower as compared with the occupying group and the splenic rupture group, and the PVT is more likely to occur. However, no difference of the PLT level is found in the patients without and with PVT.
