Objective To analyze the occurrence of acute gastrointestinal injury (AGI) after pediatric cardiac surgery with cardiopulmonary bypass (CPB) and its impact on prognosis, and to explore the risk factors and early warning indicators for AGI, in order to identify and diagnose AGI at an early stage. Methods This is a prospective observational study. The patients under 14 years with congenital heart disease receiving surgeries with CPB who were admitted to the pediatric ICU of West China Hospital, Sichuan University from December 2020 to December 2021 were included. The general information, perioperative gastrointestinal symptoms and intra-abdominal pressure, surgery-related information, postoperative organ function and prognosis of the children were collected. The patients were divided into an AGI group and a non-AGI group according to the 2012 European Society of Critical Care Medicine AGI diagnostic criteria. ResultsA total of 137 patients were enrolled, including 68 males and 69 females with a median age of 20.0 (6.0, 43.0) months. There were 60 patients in the AGI group and 77 patients in the non-AGI group, with an AGI incidence of 43.80%. The incidences of overall adverse outcomes, low cardiac output syndrome, and infectious complications were higher in the AGI group, and the vasoactive-inotropic score (VIS), mechanical ventilation time, ICU stay, and hospital stay were higher or longer in the AGI group, the differences were statistically significant (P<0.001). AGI was an independent risk factor for the overall adverse outcomes (OR=3.191, 95%CI 1.187 to 8.579, P=0.021). Univariate and multivariate logistic regression analyses indicated that weight, male, CPB time and intraoperative VIS were independent predictors for AGI after pediatric cardiac surgery. The receiver operating characteristic curve indicated that the patients with an intraoperative VIS>10.5 points and CPB time>96.5 min might have a higher possibility of postoperative AGI. ConclusionThe incidence of AGI in pediatric cardiac surgery with CPB is high, and it is an independent risk factor for overall adverse outcomes. Weight, male, CPB time , and intraoperative VIS are independent risk factors for AGI.
ObjectiveTo review the effect and safety of enhanced recovery after surgery (ERAS) in liver transplant recipients.MethodsA comprehensive literature search of Pubmed, Embase, CNKI, etc. was performed using keywords “ERAS” or “fast track” and “liver transplantation” (cut-off date June 3, 2020). The relevant literatures on researches of ERAS in liver transplant recipients at home and abroad in recent years were summarized.ResultsERAS effectively could promote the functional recovery of postoperative food intake and physical activities through systemic perioperative measures different from conventional management among the liver transplant recipients. In addition, loads of studies had revealed that ERAS was safe for liver transplant recipients with positive effects in different dimensions such as controlling complications, shortening hospital stays, and reducing medical expenses, etc.ConclusionERAS can effectively promote functional recovery of liver transplant recipients without increasing risk.
Weaning difficulty is common in critically ill patients. Prolonged mechanical ventilation and weaning failure adversely affect the clinical outcome. How to better promote and achieve the early extubation is a very important subject. As a multi-dimensional monitoring method of important structure, function and morphology, critical care ultrasound which is helpful to improve our understanding and grasp of the core links in the respiratory circuit can comprehensively evaluate the state and reserve capacity of some important organs, such as the heart, lungs and diaphragm. It has great value in assessment of weaning and guided treatment. This paper will review the application of severe ultrasound in weaning.
Living donor liver transplantation is one of the main solutions to the organ supply-demand discrepancy at present. However, there was a risk of the recipient developing small-for-size syndrome due to insufficient graft volume, while an excessively large graft volume for donation might lead to postoperative liver failure for the donor. In this context, the dual-graft liver transplantation had emerged, which could minimize the volume of liver resection from the each donor to ensure the donor’s safety and provide the adequate volume of liver for the recipient. Yet, this procedure is less commonly performed in our country. In order to promote the steady implementation of dual-graft liver transplantation in China and serve as an important supplement to the donor pool, the West China Hospital of Sichuan University organized relevant experts and draw on the mature experiences of advanced countries in the field of transplantation jointly formulated the “Expert consensus on dual-graft liver transplantation”. The consensus had been developed around aspects such as donor evaluation and selection, surgical methods, and postoperative complications.
