ABSTRACT
Through the comparison of the residency training system between China and the United States in pre-training educational background, training policy and post-training career path, it is concluded that the cardiothoracic surgery residency training in the United States has a high admission threshold, long training cycle and high education cost, but it also has the advantages of professional management, outstanding specialty characteristics and perfect evaluation system, which are suitable for the training of cardiothoracic surgeons. However, the current residency training of cardiothoracic surgery in China needs to be further improved. Learning from the advantages of the United States residency training system, we can formulate a more reasonable and professional residency training program according to Chinese own characteristics, so as to train excellent cardiothoracic surgeons for our country.
ABSTRACT
ABSTRACT Introduction: Cardiothoracic surgery (CTS) has seen a decline in interest and application rates in recent years. As a relatively small speciality, teaching and placements in CTS are often not included during undergraduate study and postgraduate training. We aim to evaluate the exposure to CTS during both undergraduate study and postgraduate training. Methods: A ten-question online survey was designed and delivered to Foundation Year Two (FY2) doctors who graduated in 2017 and completed their two-year postgraduate foundation training in 2019. Medical schools with no graduates in 2017 and 2018 were excluded from our study. IBM® SPSS Statistics, version 25, and Microsoft Excel 365® were used for Student's t-test statistical analysis. Results: Three hundred and six FY2 doctors across 16 medical schools completed the survey, none of which included compulsory CTS attachments as their undergraduate curriculum. Thirty-two respondents (10.5%) underwent CTS attachments lasting between one to three weeks. Only 14 (43.8%) had worked in a cardiothoracic unit during their two-year Foundation Programme; 10 of which (71.2%) subsequently made an application for cardiothoracic speciality training. Most of the participants with previous exposure to CTS, during either undergraduate study or postgraduate Foundation Programme training or both, were significantly more likely to make an application to CTS training (P<0.05). Conclusion: Our study suggests that doctors with increased exposure to CTS during undergraduate study and postgraduate training are more likely to pursue a career in CTS. Targeted interventions at both stages may improve interests in CTS and the number of prospective applicants.
ABSTRACT
The degree of hemodynamic support by vasoactive drugs in critically ill patients is often considered one of the markers of disease severity. The sequential organ failure assessment (SOFA), European system for cardiac operative risk evaluation Ⅱ (EuroScoreⅡ), and other scores only roughly quantify the drug support of cardiovascular system. When patients need large doses of vasoactive drugs, the mortality increases accordingly. The vasoactive-inotropic score (VIS) objectively quantifies the degree of cardiovascular support using a simple formula that standardizes the dose of different agents, and it is recommended as a simple, effective, and accurate prognostic indicator. In recent years, there are more and more clinical applications and related studies at home and abroad. This paper reviews the application and progress of VIS score in critically ill patients, providing help for doctors to judge the condition and prognosis of patients and guiding the decision-making of diagnosis and treatment.
ABSTRACT
【Objective】 To evaluate the effect of multi-disciplinary patient blood management(PBM) on perioperative blood transfusion in patients with cardiothoracic surgery of gradeⅢ~Ⅳ. 【Methods】 The blood transfusion data and relevant clinical information of adult patients underwent grade Ⅲ~Ⅳ cardiothoracic surgeries before and after PBM (from January 2016 to December 2018)in our hospital were collected using Hospital Information System and Management System of Blood Transfusion Department. Patients were grouped according to three separate12-month periods: 933 cases subjected to conventional blood transfusion practice from Jan. to Dec.2016 as the control group, 1 139 cases experienced initial implement PBM(started on Jan.1, 2017)from Jan. to Dec.2017 as the early PBM group, and 1 411 cases received improved PBM from Jan. to Dec.2018 as the improved PBM group. The perioperative autotransfusion rate, allogeneic transfusion rate, length of hospital stay and hospitalization expenses of the three groups were compared by χ2 test and variance analysis. 【Results】 The comparison results among control group, early PBM group and improved PBM group were as following: 1) The proportion of patients using iron and EPO to treat preoperative anemia were 15.12%(44/291)vs 19.73%(72/365)vs 26.65%(125/469)(P<0.01) and 10.31%(30/291)vs 12.33%(40/365)vs 15.57%(73/469)(P<0.05), respectively. 2) The incidence of autotransfusion were 57.98%(541/933)vs 44.76%(544/1 139)vs 37.00%(522/1 411)(P<0.01). The allogeneic transfusion volume per capita(U) were 351.91±35.85 vs 392.76±43.33 vs 421.75±73.84(P<0.05). The incidence of allogeneic blood transfusion were 18.11%(169/933)vs 17.56%(200/1 139)vs 13.32%(188/1 411)(P<0.01). The allogeneic blood transfusion volume per capita (U) were 6.56±8.33 vs 5.52±6.28 vs 5.56±6.17(P<0.01). 3) The per capita hospital stay (d) and ICU stay (d) were19.54±16.56 vs 16.46±12.06 vs 15.11±10.18 and 4.45±9.31 vs 3.56±6.93 vs 3.26±5.29(P<0.05), respectively. The per capita hospitalization expenses (ten thousand yuan/person) were 10.76±8.39 vs 9.58±7.58 vs 9.13±5.9(P<0.05). 【Conclusion】 The application of PBM in perioperative blood transfusionfor adult cardiothoracic surgery Ⅲ ~ Ⅳcan significantly decrease the incidence of autologous and allogeneic blood transfusion, the length of hospitalstay and hospitalization expenses.
ABSTRACT
Background and Purpose : Patients who undergo cardiac and thoracic vascular surgery are known to have a high risk of developing acute kidney injury (AKI). The incidence of post-operative acute renal failure and the utility of continuous hemodiafiltration (CHDF) for acute renal failure following cardiovascular surgery was determined. Subjects and Methods : Of the 321 subjects who underwent cardiac and thoracic vascular surgery accompanied by an open thoracotomy from January 2014 to August 2017, 303 patients were included in this study after excluding those who received maintenance dialysis and those treated with PCPS. Patients were grouped based on the GFR classification of CKD severity (preoperative eGFR values : G1 : ≥90, G2 : <90, G3a : <60, G3b : <45, G4 : <30, G5 : <15) and patient records were retrospectively examined. Results : The total incidence of AKI was 30.7%. In comparison with G1 and G2, the AKI incidence rate was significantly higher (p<0.01) in G3a, G3b, G4, and G5 patients who displayed preoperative renal dysfunction. Upon multivariate analysis, preoperative eGFR values were shown to be a predictor of post-operative AKI avoidance with a cutoff value of 56 ml/min/1.73 m2 (odds ratio = 4.104, AUC = 0.6954). The post-operative CHDF introduction rate was 3.6%. After introduction of CHDF, patient urine volume and body blood pressure significantly increased (p < 0.01). In 2 cases, a rapid increase of urine volume (2.5 ml/kg/h, 1.8 ml/kg/h) was observed within 1 h after the induction of CHDF. Conclusions : A high rate of post-operative AKI onset occurs in cardiac and thoracic surgery cases. Upon early introduction of post-operative CHDF, prompt recovery of renal function and stabilization of circulatory dynamics can be expected.

ABSTRACT
INTRODUCCIÓN: los procedimientos de cirugía cardiotorácica mínimamente invasiva (MICS, su sigla en Inglés) buscan reducir las complicaciones de las grandes disecciones. No obstante, ante la falta de contacto directo con el tejido por parte del cirujano, éste recibe una sensación parcial de tacto y fuerza, lo que puede originar errores de procedimiento, inadecuada fuerza aplicada al tejido y fatiga durante el acto quirúrgico. La inclusión de dispositivos robóticos con la técnica MICS ha potencializado las habilidades del cirujano para la manipulación de los tejidos, y aunque los desarrollos del mercado no cuentan aún con retroalimentación táctil, se trabaja en prototipos robóticos que incorporan realimentación de fuerza y torque. OBJETIVO: proponer las condiciones y restricciones relacionadas con la incorporación de realimentación de fuerza y torque en MICS robótica, aplicables a diferentes configuraciones de manipuladores, y analizar la implementación de dichas condiciones en un simulador quirúrgico. MATERIAL Y MÉTODOS: partiendo del análisis de necesidades durante procedimientos cardiotorácicos y las condiciones de cirugía mínimamente invasiva, se identificaron los requerimientos para garantizar reflexión de fuerza y se realizó un análisis matemático de dichas consideraciones. Finalmente, se verificaron los análisis matemáticos mediante técnicas de modelización y simulación utilizando la plataforma computacional Matlab®. RESULTADOS: se argumentaron tres tipos de consideraciones: a) Cinemático: la existencia de un punto fijo, las formas de garantizarlo durante procedimientos MICS robóticos, y las trayectorias de movimiento que el manipulador sigue en aplicaciones de cirugía cardiotorácica; b) Dinámico: la repercusión de fuerzas externas en el manipulador y la manera de considerarlas en el desarrollo de controladores que permitan al cirujano percibir una sensación de contacto con el tejido; c) Sensorial: requerimientos de los sensores de fuerza y relación necesaria entre el número de sensores y actuadores para realimentar fuerza en MICS robótica. Posteriormente se implementaron dichas consideraciones en un simulador y se verificó el cumplimiento de las mismas. CONCLUSIONES: las condiciones relacionadas con la incorporación de un sensor de fuerza y la percepción del cirujano en cuanto al tacto y la fuerza aplicada, resultan ser importantes en procedimientos de MICS robótica y requiere la inclusión de un sistema de control que permita la optimización de procedimientos por telepresencia.
INTRODUCTION: the procedures in minimally invasive cardiothoracic surgery (MICS) aim to reduce the complications of major dissections. However, in the absence of direct contact of the surgeon with the tissue, he receives a partial sense of touch and strength, which can lead to procedural errors, inadequate force applied to the tissue and fatigue during surgery. The inclusion of robotic devices with the MICS technique has enhanced the technical skills of the surgeon to manipulate tissue, and although the market devices still do not have tactile feedback, research in robotic prototypes that incorporate feedback of force and torque is being done. OBJECTIVE: to propose the conditions and restrictions related to the integration of force and torque feedback in robotics MICS applicable to different configurations of manipulators and analyze the implementation of those conditions in a surgical simulator. MATERIAL AND METHODS: from the analysis of needs during cardiothoracic procedures and conditions of minimally invasive surgery, we identified the requirements to ensure reflection of force and performed a mathematical analysis of such considerations. Finally, mathematical analysis were verified by modeling and simulation techniques using the Matlab® computing platform. RESULTS: three types of considerations were argued: a) Kinematic: the existence of a fixed point; the way to guarantee it for robotic MICS procedures, and the trajectories of motion followed by the controller in the applications of Cardiothoracic Surgery, b) Dynamic: the impact of external forces on the manipulator and the way to consider them in the development of controllers that allow the surgeon to feel a sense of contact with the tissue, c) Sensory: requirements of the force sensors and necessary relationship between the number of sensors and actuators to feedback force in MICS robotics. Subsequently these considerations were implemented in a simulator and were checked for compliance. CONCLUSIONS: the conditions related to the incorporation of a force sensor and the perception of the surgeon in terms of touch and force applied turns out to be important in robotics MICS procedures and requires the inclusion of a control system that enables the optimization of telepresence procedures.
