ObjectiveTo investigate clinical outcomes and safety of minimally invasive left atrial myxoma (LAM) resection via right anterolateral minithoracotomy (ALMT). MethodsClinical data of 9 patients who underwent minimally invasive LAM resection via right ALMT in the Affiliated Hospital of Luzhou Medical College from January 2011 to October 2013 were retrospectively analyzed. There were 2 male and 7 female patients with their age of 37-62 (51±9) years. The operation was performed through a small (4-6 cm) right ALMT incision. Femoral artery and vein and superior vein were cannulated to establish cardiopulmonary bypass (CPB). Transthoracic clamp was used for ascending aortic clamping. Antegrade cold blood cardioplegia was infused for myocardial protection. LAM was resected through right atriotomy trans-septal approach. ResultsAll the operations were successfully performed without in-hospital death. Operation time was 210-310(260±33) minutes, aortic cross-clamping time was 23-50(37±9) minutes, CPB time was 60-87(71±9) minutes, postoperative mechanical ventilation time was 6-14(9.0±2.5) hours, and length of ICU stay was 17-26(20±3) hours. Postoperative mediastinum drainage was 100-650(376±190) ml. Mean length of right ALMT was 4.5-6.0 (5.3±0.6) cm. All the patients were followed up for 1 to 30 months,and echocardiography showed no LAM recurrence. ConclusionMinimally invasive LAM resection via right ALMT is safe and feasible with satisfactory clinical outcomes.
ObjectiveTo systematically evaluate the efficacy of different interventions in preventing rocuroniuminduced injection pain or withdrawal movements, so as to provide references for preventing adverse reactions induced by rocuronium injection in clinical practice. MethodsWe electronically searched PubMed, EMbase, The Cochrane Library (Issue 3, 2014), CBM, and CNKI databases to collect randomized controlled trials (RCTs) about the prevention of rocuronium-induced injection pain or withdrawal movements from inception to March 2014. Two reviewers independently screened literature, extracted data, and assessed the risk of bias of included studies. Then, meta-analysis was performed using RevMan 5.2.8 software. ResultsA total of 43 RCTs involving 6 034 patients were include. The results of meta-analysis showed that compared with the placebo/blank group, lidocaine pretreatment with venous occlusion (RR=0.37, 95%CI 0.29 to 0.48, P<0.000 01), opioid drug pretreatment with venous occlusion (RR=0.77, 95%CI 0.68 to 0.87, P<0.000 1), lidocaine pretreatment with venous injection (RR=0.51, 95%CI 0.44 to 0.59, P<0.000 01), opioid drug pretreatment with venous injection (OR=0.03, 95%CI 0.02 to 0.05, P<0.000 01), ketamine pretreatment with venous injection (RR=0.36, 95%CI 0.23 to 0.54, P<0.000 01), mixing sodium bicarbonate (NaHCO3) with rocuronium (OR=0.02, 95%CI 0.01 to 0.04, P<0.000 01) and local heating (RR=0.74, 95%CI 0.63 to 0.88, P=0.000 6) were all effective in decreasing the incidence of rocuronium-induced injection pain or withdrawal movements. ConclusionThe intravenous injection of opioid drugs was effective in preventing rocuronium-induced injection pain or withdrawal movements, while local heating needs further research. Due to the limited quantity and quality of the induced studies, the above conclusion still needs to be verified by more high quality studies.
ObjectiveTo systematically review the effectiveness of non-depolarizing neuromuscular blockers for the prevention of succinylcholine-induced myalgia in clinical practice. MethodsDatabases including PubMed, EMbase, The Cochrane Library (Issue 2, 2014), WanFang Data, CBM and CNKI were searched to collect the randomized controlled trails (RCTs) about non-depolarizing neuromuscular blockers for the prevention of succinylcholine-induced myalgia from inception to March 2014. Two reviewers independently screened literature according to the inclusion and exclusion criteria, extracted data, and assessed methodological quality of included studies. Then meta-analysis was conducted using RevMan 5.2 software. ResultsA total of 11 RCTs involving 666 patients were included. The results of meta-analysis showed that:the pre-treatment of non-depolarizing neuromuscular blockers prevented succinylcholine-induced myalgia at 24 h after surgery (RR=0.46, 95%CI 0.39 to 0.55, P<0.000 01); however, the effectiveness of non-depolarizing neuromuscular blockers for prevention of succinylcholine-induced myalgia at 48 h after surgery was still unclear. ConclusionCurrent studies suggests that both rocuronium and atracurium are effective for the prevention of succinylcholine-induced myalgia. However, due to limited quantity and quality of the included studies, more high-quality studies are needed to verify the abovementioned conclusion.
ObjectiveTo analyze clinical outcomes of mitral valvuloplasty (MVP) via right anterolateral minithoracotomy. MethodsClinical data of 23 patients with valvular heart disease who underwent minimally invasive MVP via right anterolateral minithoracotomy from January 2011 to February 2013 in the Department of Cardiothoracic Surgery in our hospital were retrospectively analyzed. There were 8 males and 15 females with mean age of 41±10 years. The procedure was performed through a small (4-6 cm) incision via right anterolateral minithoracotomy. Cardiopulmonary bypass (CPB) was established via femoral artery and vein cannulation. Transthoracic clamp was used for ascending aortic clamping. Cold blood cardioplegia was delivered after aortic cross-clamping. Left atrial drainage was established through right superior pulmonary vein. MVP was performed through the atrial septal approach,and tricuspid valvuloplasty was performed for tricuspid regurgitation if necessary. ResultsAll the operations were successfully performed without in-hospital death. Operation duration was 160-290 (229±37) minutes. Aortic cross-clamping time was 40-121 (67±19) minutes. CPB duration was 60-136 (87±21) minutes. Postoperative mechanical ventilation time was 6-47 (16±11) hours. The length of intensive care unit stay was 19-60 (30±12) hours. Postoperative chest drainage was 80-780 (320±184) ml. Postoperative color Doppler echocardiography showed that left ventricular ejection fraction was 49%-65% (56.0%±4.8%). There were 5 patients with trivial mitrial valve regurgitation and 6 patients with mild tricuspid valve regurgitation. Postoperative mean length of the right thoracic incision was 3.9-6.0 (5.3±0.7) cm. The patients were followed up for 1-24 months. The result of echocardiography showed no modern to severe valve regurgitation. ConclusionMinimally invasive MVP via right anterolateral minithoracotomy is safe and feasible with satisfactory cosmetic and clinical results.
The validity and reasonableness of emotional data are the key issues in the cognitive affective computing research. Effects of the emotion recognition are decided by the quality of selected data directly. Therefore, it is an important part of affective computing research to build affective computing database with good performance, so that it is the hot spot of research in this field. In this paper, the performance of two classical cognitive affective computing databases, the Massachusetts Institute of Technology (MIT) cognitive affective computing database and Germany Augsburg University emotion recognition database were compared, their data structure and data types were compared respectively, and emotional recognition effect based on the data were studied comparatively. The results indicated that the analysis based on the physical parameters could get the effective emotional recognition, and would be a feasible method of pressure emotional evaluation. Because of the lack of stress emotional evaluation data based on the physiological parameters domestically, there is not a public stress emotional database. We hereby built a dataset for the stress evaluation towards the high stress group in colleges, candidates of postgraduates of Ph.D and master as the subjects. We then acquired their physiological parameters, and performed the pressure analysis based on this database. The results indicated that this dataset had a certain reference value for the stress evaluation, and we hope this research can provide a reference and support for emotion evaluation and analysis.
ObjectiveTo explore the curative effect and value of laparoscopic operation in the treatment of acute gangrenous and perforated appendicitis. MethodsThe clinical data of 243 patients with acute gangrenous and perforated appendicitis from February 2011 to February 2014 in our hospital were retrospectively analyzed. Laparoscopic appendectomy was performed in 118 cases (LA group), and open appendectomy was performed in 125 cases (OA group). The operative time, hospital stay, hospital costs, incision bleeding, gastrointestinal function recovery, wound infection, pelvic abscess, and postoperative adhesions of two groups were compared. ResultsThere was no significant difference in the operative time, incision bleeding, and the incidence of pelvic abscess after operation between the LA group and OA group (P>0.05). Compared with the OA group, the recovery time of gastrointestinal function was significantly shortened (P<0.01), eating time was earlier (P<0.01), hospitalization time also shortened significantly (P<0.01), and the incidence of postoperative wound infection and intestinal adhesion were significantly decreased (P<0.01) after operation in LA group. But the cost of hospitalization in LA group increased significantly (P<0.05). ConclusionsThe laparoscopic operation in the treatment of gangrenous and perforated appendicitis are light of pain., recover quickly, shorter of hospital stay, and fewer complications. The increase of hospitalization expenses is the only deficiency.
Lung transplantation has been a standard treatment option for patients with end-stage lung disease. However, the demand for donor lungs exceeds the poor of available organs, resulting in considerable waiting list mortality. Among all the useful methods so far, ex vivo lung perfusion (EVLP) has been considered a useful technique in lung transplantation, which helps prolong donor lung preservation and repair donor lung injuries. Current studies have demonstrated EVLP can evaluate the donor lung function continuously and provide platform for pharmaceutical or even gene therapy. Moreover, EVLP improves the function of marginal donor lungs and increases the quantity of lungs meeting the transplant criteria, which could extend the donor pool. This article reviews the clinical application and research progress of EVLP in lung transplantation.
ObjectiveTo explore whether preoperative coronary angiography could increase the incidence of postoperative acute kidney injury for patients with valve replacement. MethodsA total of 638 patients underwent routine cardiac valve replacement in our hospital from January 2013 through September 2015. There were 118 patients with preoperative coronary angiography (a coronary angiography group), and 520 patients without coronary angiography (a non-coronary angiography group). Serum creatinine (Scr), urea nitrogen(Bun), brain natriuretic peptide (BNP), creatine kinase myocardial band (CK-MB), cardiac troponin I (cTnI) values were recorded at 4 time points:before surgery (T0), after surgery 12 h (T1), 24 h (T2), 48 h (T3). The number of patients with acute kidney injury at the time of 48 hours after surgery was recorded. ResultsScr values (91.6±37.7 μmol/L vs. 81.0±27.4 μmol/L, 84.9±23.6 μmol/L vs. 73.5±25.3 μmol/L) increased in the patients who did not undergo coronary angiography at the time of 24 hours and 48 hours after cardiac surgery compared with the patients with coronary angiography with statistical differences. While there was no statistical difference in the incidence of acute kidney injury between the two groups. The cardiac enzymes had no statistical difference between the two groups. ConclusionPreoperative coronary angiography does not increase the probability of postoperative acute kidney injury.
