ObjectiveTo probe into the clinical effects of intra-amniotic injection of ethacridine with Cook cervical ripening balloon in terminating mid-pregnancy. MethodsA total of 150 mid-pregnant women who required induction of labor from January 2011 to December 2012 were randomly divided into two groups: observation group (intra-amniotic injection of ethacridine with Cook cervical ripening balloon) and control group (intra-amniotic injection of ethacridine). ResultsThe time of labor induction was obviously shorter in the observation group than the control group [the time from using ethacridine to contraction: （29.68±4.17） vs (33.60±5.38) hours, P<0.05; total process: (7.63±2.30) vs (9.86±3.20) hours, P<0.05], and the residual rate of placental membranes [28.6% (10/35) vs 56.4%(22/39), P<0.05] was significantly lower. But there was no significant difference in postpartum hemorrhage [(81.60±17.64) vs (83.82±15.08 ) mL, P>0.05] and rate of success [100.0% (35/35) vs 94.9% (37/39), P>0.05]. ConclusionTerminating mid-pregnancy by intra-amniotic injection of ethacridine with Cook cervical ripening balloon has the advantages of shorter time and less pain, which deserves clinical application widely.
ObjectiveTo monitor surgical quality and analyze learning curve of minimally invasive mitral valve replacement (MVR)through right minithoracotomy with cumulative sum analysis (CUSUM analysis). MethodsClinical data of 60 consecutive patients who underwent minimally invasive MVR through right minithoracotomy in the Fourth Affiliated Hospital of Guangxi Medical University from June 2011 to April 2013 were retrospectively analyzed. There were 32 male and 28 female patients with their age of 28-53 (34.67±7.11)years and their heart function ranging from NYHA class Ⅱ to Ⅳ. There were 31 patients with mitral stenosis (MS), 19 patients with mitral regurgitation (MR), and 10 patients with MS and MR. According to the surgical sequence, all the patients were divided into 3 groups (group A, B and C)with 20 patients in each group. Surgical outcomes were compared among the 3 groups, and surgical quality was analyzed with descriptive statistics and CUSUM curves. ResultsAortic cross-clamp time, cardiopulmonary bypass time and operation time of group C were significantly shorter than those of group A and group B (aortic cross-clamp time of group C vs. group A:50.35±2.30 minutes vs. 66.15±8.38 minutes; operation time of group C vs. group B:167.50±4.63 minutes vs. 178.60±4.49 minutes, P < 0.05). In-hospital mortality was 3.3% (2/60). CUSUM analysis showed a significant learning curve effect, although surgical quality remained in control during the study period. Surgical failure rate was lower than 80% after about 45 operations, indicating that failure rate was 10% lower than expectation. ConclusionMinimally invasive MVR is safe and reliable, and CUSUM analysis is a simple statistical method to monitor surgical quality.
ObjectiveTo summarize surgical strategies, early and long-term outcomes of concomitant surgical treatment for patients with both coronary artery disease (CAD) and lung cancer (LC). MethodsWe retrospectively analyzed clinical data of 15 patients who underwent concomitant surgical treatment for both CAD and LC in Xinhua Hospital, School of Medicine of Shanghai Jiaotong University from January 2006 to January 2014. There were 11 male and 4 female patients with their age of 52-73 years. Preoperative clinical staging of LC was stageⅠtoⅡb (TNM), and postoperative pathological result of most patients (11 patients) was adenocarcinoma. All the patients had normal heart and pulmonary function. All the 15 patients received off-pump coronary artery bypass grafting (OPCAB) via median sternotomy. After OPCAB, 9 patients underwent radical LC resection via median sternotomy, and 6 patients underwent radical LC resection with video-assisted thoracoscopic surgery (VATS). ResultsThere was no in-hospital death or newonset myocardial infarction. Pathological diagnosis included squamous LC in 4 patients and adenocarcinoma in 11 patients. Pathological TNM staging wasⅠb in 4 patients, Ⅱa in 6 patients, andⅡb in 5 patients. Postoperative complications included arrhythmias, atelectasis, and pulmonary infection. All the patients were followed up for 6 months to 5 years. Three patients died during follow-up. None of the patients received redo revascularization or LC resection. ConclusionConcomitant OPCAB and LC resection is a safe and efficacious treatment choice for patients with both CAD and LC.
ObjectiveTo systematically evaluate the association between 936C/T polymorphism in vascular endothelial growth factor (VEGF) gene and the risk of preeclampsia (PE). MethodsSuch databases as PubMed, EMbase, The Cochrane Library (Issue 11, 2014), CBM, CNKI, VIP, and WanFang Data were searched up to November 2014, to collect case-control studies of the association between 936C/T polymorphism in VEGF gene and the risk of PE. Two reveiwers independently screened studies according to the inclusion and exclusion criteria, extracted data, and assessed the risk of bias of included studies. And then, meta-analysis was conducted using RevMan 5.3 software. ResultsA total of nine case-control studies involving 904 PE patients and 1 113 controls were included. The results of meta-analysis showed that, significant association was found between VEGF gene 936C/T polymorphism and the risk of PE in the total analysis (T vs. C:OR=1.61, 95%CI 1.17 to 2.22, P=0.003; TT vs. CC:OR=2.65, 95%CI 1.37 to 5.11, P=0.004; CT vs. CC:OR=1.55, 95%CI 1.09 to 2.22, P=0.02; TT+CT vs. CC:OR=1.68, 95%CI 1.15 to 2.45, P=0.007; TT vs. CT+CC:OR=2.19, 95%CI 1.31 to 3.68, P=0.003). In the subgroup analysis, significant association of the polymorphism was found in Asians but not in Caucasians. ConclusionVEGF gene 936C/T polymorphism may be associated with PE risk in Asians. Due to limited quantity and quality of the included studies, the conclusion should be assessed in further studies.
ObjectiveTo discuss the intraoperative anesthesia management for complete thoracoscopic surgical atrial fibrillation (AF) ablation via the left chest. MethodsWe retrospectively analyzed the clinical data of 201 patients (106 males and 95 females aged 58.7±15.4 years) with AF underwent complete thoracoscopic surgical ablation via the left chest in Department of Cardiothoracic surgery, Xinhua Hospital From September 2010 through December 2013. ResultsAll the patients successfully underwent the minimally invasive ablation procedure. No patient required conversion to sternotomy during the surgery. The average time of operation was 104.9±37.2 min. During the ablation procedure, the patients' blood pressure and arterial oxygen saturation (SpO2) reduced at different levels. The average minimum arterial blood pressure was 44-79 (62.4±8.4) mm Hg. The average minimum SpO2 was 83%-95% (88.8%±3.1%). After the ablation, the patients' respiratory function and hemodynamic gradually recovered. The average heart rate was 40-108 (70.0±16.6) bpm when sinus rhythm was restored. The maintenance of sinus rhythm rate was 94.5% (190/201) at discharge. There was no early death, stroke, hemorrhage or permanent pacemaker implantation during perioperation. ConclusionComplete thoracoscopic surgical AF ablation via the left chest has some influence on patients' respiratory function and hemodynamic. Reasonable anesthetic management can ensure the minimally invasive ablation procedure safe and effective.
ObjectiveTo assess the effect of a novel modified epicardial radiofrequency (RF) ablation for preoperative atrial fibrillation (AF) combined with aortic valve disease. MethodsWe retrospectively analyzed the clinical data of 28 patients with AF and aortic valve disease underwent the novel modified epicardial RF ablation combined with aortic valve replacement (AVR) in our hospital between December 2009 and December 2014. There were 18 males and 10 females at age of 53-73 (64.9±4.8) years. The patients were performed epicardial atrial fibrillation RF ablation plus aortic valve replacement. ResultsThe modified epicardial RF ablation and AVR were performed successfully in all the patients. The maintenance of sinus rhythm was 96.4% (27/28) at discharge. There were no early death and permanent pacemaker implantation in perioperation. At a mean following-up of 29.2±17.7 months, 26 of 28 (92.9%) patients were in sinus rhythm. Following-up transthoracic echocardiography(TTE) at 6 months postoperatively showed that left atrial diameter was significantly reduced and left ventricular ejection fraction was significantly increased. ConclusionThe novel modified epicardial RF ablation procedure is safe, feasible, and effective. It may be useful in selecting the best ablation approaches for patients with AF and aortic valve disease.
