ABSTRACT
@#Objective To investigate the influence of prior percutaneous coronary intervention (PCI) on the outcome of coronary artery bypass grafting (CABG). Methods Clinical data of 5 216 patients from Jiangsu Province CABG registry who underwent primary isolated CABG from 2016 to 2019 were retrospectively analyzed. Patients were divided into a PCI group (n=673) and a non-PCI group (n=4 543) according to whether they had received PCI treatment. The PCI group included 491 males and 182 females, aged 62.6±8.2 years, and the non-PCI group included 3 335 males and 1 208 females, aged 63.7±8.7 years. Multivariable logistic regression and propensity score matching (PSM) were used to compare 30-day mortality, incidence of major complications and 1-year follow-up outcomes between the two groups. Results Both in original cohort and matched cohort, there was no statistical difference in the 30-day mortality [14 (2.1%) vs. 77 (1.7%), P=0.579; 14 (2.1%) vs. 11 (1.6%), P=0.686], or the incidence of major complications (myocardial infarction, stroke, mechanical ventilation≥24 h, dialysis for new-onset renal failure, deep sternal wound infection and atrial fibrillation) (all P>0.05). The rate of reoperation for bleeding in the PCI group was higher than that in the non-PCI group [19 (2.8%) vs. 67 (1.5%), P=0.016; 19 (2.8%) vs. 7 (1.0%), P=0.029]. Both in original cohort and matched cohort, there was no statistical difference in 1-year survival rate between the two groups [613 (93.1%) vs. 4 225 (94.6%), P=0.119; 613 (93.1%) vs. 630 (95.2%), P=0.124], while the re-admission rate in the PCI group was significantly higher than that in the non-PCI group [32 (4.9%) vs. 113 (2.5%), P=0.001; 32 (4.9%) vs. 17 (2.6%), P=0.040]. Conclusion This study shows that a history of PCI treatment does not significantly increase the perioperative mortality and major complications of CABG, but increases the rate of cardiogenic re-admission 1 year postoperatively.
ABSTRACT
Objective Objective Structured Clinical Examination (OSCE) is one of the most important methods for evalua-ting the medical students′clinical ability .The aim of this study was to analyze the value of OSCE on practice examination in the depart -ment of cardiothoracic surgery . Methods Through the use of standardized patients and the six-station clinical examination , we as-sessed the clinical skills of interns in the department of cardiothoracic surgery . Results OSCE could appraise interns′clinical ability objectively and accurately , which obtained the recognition from students . Conclusion OSCE is applicable to the clinical skills tes-ting in the department of cardiothoracic surgery .
ABSTRACT
Objective The stentless full root aortic bioprosthesis has superior hemodynamics.Clinical data of Bio-Bentall procedure using stentless full root bioprosthesis of our center was retrospectively analyzed in this perspective for validation.Methods From November 2001 to March 2009,317 adult patients ( 196 male and 121 female) underwent modified Bio-Bentall procedure using the Medtronic Freestyle xenograft as a full root replacement.Two hundred and three patients received an isolated root replacement or a root and ascending aortic replacement (ARR).In 114 patients a variety of concomitant procedures including coronary artery bypass grafting ( n =32 ),mitral valve repair ( n =11 ) and aortic arch replacement ( n =36 ) were performed.(ARR + ).Results Mean patient age was (70.3 ± 10.2) years (range 17 -94 years),97 patients were 75 and older at time of procedure.Mean operative time for the ARR was ( 190 ± 57 ) min with a clamp time of 88 - 27 min.Mean operative time for ARR + group was (282 ±93) min with an average clamp time of (110 ±32) min.Overall operative mortality was 7.9％ (25/317),for ARR it was 5.4％ (11/203 ).Mean ICU stay was (4.9 ± 8.1 ) days,mean hospital stay being (9.8 ± 8.1 ) days.Necessity for bailout bypass surgery among patients with ARR was low at 1.5％ (3/203) comparable to stented xenograft implantations.Echocardiography demonstrated excellent clinical results with low transvalvular gradients especially when a single suture inflow anastomosis technique was used.Conclusion Full root stentless valve implantation preserving porcine root integrity is a valuable option in aortic valve/ascending aorta surgery.Though technically a more challenging operation,it does not lead to increased perioperative morbidity and mortality and can be beneficial mainly for elderly patients with small aortic roots with or without aortic root pathology.
ABSTRACT
Objective To study the short-term(≤1 year) effect of video-thoracoscope in the treatment of chronic obstructive pulmonary diseases (COPD) accompanied with pneumothorax.Methods 52 COPD cases with pneumothorax from June 2005 to June 2007 were divided into thoracoscope group(n=28) and open heart group(n=24).The patients were followed up at 1,6 and 12 month after surgery,for determination of BODE index,including body mass index,air block,difficulty in respiratory and motor ability.Results No operative death and servere complicatins occurred.Pneumothorax did not relapse.One month after surgery,air block was[(58.62±15.73)% vs (50.12±11.38)%],difficulty in respiratory was[(1.04±0.37)s vs( 1.72±0.45)s] and motor ability was [(387.32±52.07)m vs (318.35±61.52)m] in thoracoscope group and open heart group (P<0.05).At the six month after surgery,body mass index was[(27.19±2.18)kg/m2 vs (20.90±2.35)kg/m2] in thoracoscope group and open heart group(P<0.05);At the 12 month after operation,there was no significant difierence in BODE index between the two groups(P>0.05).Conclusions Video-thoracoscope in treating COPD with pneumothorax can remarkably improve the quality of life early after surgery.
ABSTRACT
Objective To observe the two different wetting fluid in airway humidification of patients with mechanical ventilation.Methods 40 patients with mechanical ventilation after cardiac surgery in our hospital from January to April,2009,were divided randomly into group A and group B,group A was given 0.45% sodium chloride solution 100ml plus ambroxol 15mg as airway humidification fluid,group B was given sterile water for injection100 ml plus ambroxol 15mg as airway humidification liquid.The amount of sputum aspiration,color,viscosity,the body temperature of patients,the lungs auscultation and chest X-ray were observed.Results No statistical difference was seen in sputum volume,color,viscosity,the body temperature of patients,lungs auscultation as well as chest X ray after mechanical ventilation for 4 hours,8 hours,16 hours,24 hours,1～2 d,3～5 d,6～7 d.No statistical difference was also seen in auscultation of the lung after mechanical ventilation for 4 hours,16 hours,24 hours,1～2 d,3～5 d,6～7 d.But auscultation of the lung in group B was better than that of group A after mechanical ventilation for 8 hours.Conclusions No sufficient fact can prove that different effect exists between 100 ml 0.45% sodium chloride solution plus ambroxol 15mg and 100 ml sterile water for injection plus ambroxol 15mg as airway humidification fluid during mechanical ventilation.
