Objective To summarize the experience of open heart operation on neonates with critical and complex congenital heart diseases and evaluate the methods of perioperative management. Methods From May 2001 to January 2003, 12 patients of neonates with congenital heart diseases underwent emergency operation. Their operating ages ranged from 6 to 30 days, the body weights were 2.8 to 4.5 kg. Their diagnoses included D-transposition of the great arteries in 4 cases, ventricular septal defect with atrial septal defect in 5 cases, complete atrioventricular septal defect, obstructed supracardiac total anomalous pulmonary venous drainage and cardiac rhabdomyomas in 1 case respectively. 12 cases were operated under moderate or deep hypothermic cardiopulmonary bypass. Results All cases were observed in ICU for 2-11 days and discharged 7-19 days after operation. The postoperative complications included low cardiac output, mediastinal infection, respiratory distress syndrome, systemic capillary leak syndrome and acute renal failure. All cases were cured and the follow-up (from 6 months to 2 years) showed satisfactory outcome. Conclusion A particular cardiopulmonary bypass and proper perioperative management is very important to ensure the successful outcome. Peritoneal dialysis is an effective and safe method for treating acute renal failure after cardiac operation in neonates.
Minimally invasive cardiac surgeries are the trend in the future. Among them, robotic cardiac surgery is the latest iteration with several key-hole incision, 3-dimentional visualization, and articulated instrumentation of 7 degree of ergonomic freedom for those complex procedures in the heart. In particular, robotic mitral valve surgery, as well as coronary artery bypass grafting, has evolved over the last decade and become the preferred method at certain specialized centers worldwide because of excellent results. Other cardiac procedures are in various stages of evolution. Stepwise innovation of robotic technology will continue to make robotic operations simpler, more efficient, and less invasive, which will encourage more surgeons to take up this technology and extend the benefits of robotic surgery to a larger patient population.
ObjectiveTo evaluate the continuous half-thickness suture outside of the pectinate muscles in the right atrium incision in adult patients undergoing cardiac surgery. MethodsA total of 1 040 consecutive adult patients undergoing cardiac surgery by the right atrium incision with cardiopulmonary bypass (CPB) were randomly divided into a control group (n=518 with 236 males and 282 females at mean age of 44.55 years) and a trial group (n=522 with 242 males and 280 females at mean age 45.75 years) between January 2010 and June 2014. The right atrium incision was sutured by continuous full-thickness suture in the control group and sutured by continuous half-thickness suture in the trial group. After the suture, the bleeding in the right atrium incision was recorded. ResultsAll patients underwent the open-heart operation. Seven patients died of postoperative low cardiac syndrome including four patients in the control group and 3 patients in the trial group. The heart incision was inspected before suturing the pericardium. A total of 203 patients of local active bleeding were stitched again in the right atrium incision in the control group. Only 26 patients were stitched again in the trial group (P<0.001). In the cases of re-exploration for bleeding or tamponade after cardiac operation, 3 patients of bleeding due to the right atrium incision were confirmed in the control group, and no one was confirmed in the trial group. ConclusionThe continuous half-thickness suture in the right atrium incision can prevent the incision bleeding, and avoid locally stitching again in adult patients undergoing cardiac surgery.
Objective To investigate the relationship between two-lung ventilation (TLV) with single-lumen endotracheal tube (SLT), one-lung ventilation (OLV) with double-lumen endotracheal tube (DLT) and postoperative pulmonary complications (PPCs) after total thoracoscopic cardiac surgery. Methods The clinical data of patients who underwent totally thoracoscopic cardiac surgeries in the Guangdong Provincial People’s Hospital from October 2019 to October 2021 were retrospectively analyzed. The patients were divided into 2 group according to the type of endotracheal tube, including a SLT group and a DLT group. Baseline data, surgical variables and PPCs were compared. The influencing factors of PPCs in the two groups were analyzed by binary logistic regression analysis. Results Finally 349 patients were enrolled, including 180 males and 169 females with an average age of (50.0±14.8) years. There were 219 patients in the SLT group and 130 patients in the DLT group. There was no statistical difference in baseline data, surgical variables or PPCs between the two groups (P＞0.05). Binary logistic regression analysis showed that PPCs were related to body mass index in the SLT group (OR=0.778, 95%CI 0.637 to 0.951, P=0.014) and preoperative smoking history in the DLT group (OR=0.058, 95%CI 0.004 to 0.903, P=0.042). Conclusion For the patients who undergo totally thoracoscopic cardiac surgery, TLV with SLT and OLV with DLT show no significant association with PPCs. At the same time, PPCs are associated with body mass index in the SLT group, while associated with preoperative smoking history in the DLT group.
ObjectiveTo evaluate the association of intraoperative ventilation modes with postoperative pulmonary complications (PPCs) in adult patients undergoing selective cardiac surgery under cardiopulmonary bypass (CPB).MethodsThe clinical data of 604 patients who underwent selective cardiac surgical procedures under CPB in the West China Hospital, Sichuan University from June to December 2020 were retrospectively analyzed. There were 293 males and 311 females with an average age of 52.0±13.0 years. The patients were divided into 3 groups according to the ventilation modes, including a pressure-controlled ventilation-volume guarantee (PCV-VG) group (n=201), a pressure-controlled ventilation (PCV) group (n=200) and a volume-controlled ventilation (VCV) group (n=203). The association between intraoperative ventilation modes and PPCs (defined as composite of pneumonia, respiratory failure, atelectasis, pleural effusion and pneumothorax within 7 days after surgery) was analyzed using modified poisson regression. ResultsThe PPCs were found in a total of 246 (40.7%) patients, including 86 (42.8%) in the PCV-VG group, 75 (37.5%) in the PCV group and 85 (41.9%) in the VCV group. In the multivariable analysis, there was no statistical difference in PPCs risk associated with the use of either PCV-VG mode (aRR=0.951, 95%CI 0.749-1.209, P=0.683) or PCV mode (aRR= 0.827, 95%CI 0.645-1.060, P=0.133) compared with VCV mode. ConclusionAmong adults receiving selective cardiac surgery, PPCs risk does not differ significantly by using different intraoperative ventilation modes.
Objective To evaluate the clinical efficacy of dexmedetomidine in perioperative management of on-pump cardiac surgery. Methods Randomized controlled trials (RCTs) were identified through a systematic literature search of PubMed, EBSCO, Web of Science, Cochrane Library, CBM, CNKI, Wanfang Database (up to December 2016). RevMan 5.3 software was used for meta-analysis. Results Sixteen studies with 1 432 patients were included. Dexmedetomidine significantly decreased the risk of postoperative delirium (RR=0.28, 95% CI 0.18 to 0.44, P<0.000 01) and postoperative atrial fibrillation (RR=0.65, 95% CI 0.44 to 0.98, P=0.04) compared with the controls. The duration of intubation (RR=–1.96, 95% CI –2.07 to –1.86, P<0.000 01), length of ICU stay (RR=–0.49, 95% CI –0.74, –0.24, P=0.000 1) and hospital stay (RR=–1.24, 95% CI –2.26 to –0.22, P=0.02) in the dexmedetomidine group were significantly shorter than those of the control group. In addition, dexmedetomidine was shown to improve the score of the the Montreal Cognitive Assessment (RR=0.88, 95% CI 0.42 to 1.35, P=0.000 2) compared to the control group. Conclusion Dexmedetomidine can reduce the complications after cardiac surgery, which is safe and effective. However, more studies with good methodologic quality and large samples are still needed to make further assessment.
ObjectiveTo summarize the experience of applying extracorporeal membrane oxygenation (ECMO) after cardiac surgery in adult patient. MethodsWe retrospectively analyzed the clinical data of 27 patients underwent ECMO from December 2011 to October 2013. There were 15 males and 12 females at the mean age of 51±11 years ranging from 41 to 73 years. Vein-artery perfusion was performed in all 27 patients. ResultsAll 27 patients underwent ECMO. The mean time of using ECMO was 81.2±36.4 hours ranging from 48.0-192.0 hours. The mean time of hospital stay was 307.8±97.0 hours ranging from 168.0-480.0 hours. The rate of weaning from ECMO was 77.8% (21/27). The rate of discharge was 51.9% (14/27). The rate of perioperative mortality was 44.4% (12/27). ConclusionEffective monitoring with other supportive equipments is helpful to promote the result of ECMO.
