Objective To identify and quantify independent risk factors for poor perioperative outcomes in neonates with transposition of the great arteries (TGA) and arterial switch operation (ASO), and establish a predictive model for risk stratification and perioperative management optimization. Methods A retrospective analysis was conducted on the clinical data of neonatal TGA patients treated with ASO at Guangdong Provincial People's Hospital from January 1998 to August 2024. The research variables included baseline characteristics, preoperative parameters, surgical variables, and postoperative management indicators. The main outcome was perioperative composite adverse events. Multiple logistic regression was used to screen for independent risk factors and construct a predictive model. Results Finally, 376 patients were enrolled, including 306 (81.4%) males and 70 (18.6%) females, with a median gestational age of 39 weeks and an average age of visit of (3.86±5.76) days. The 167 (44.4%) patients experienced poor prognosis. Low admission length [OR=0.726, 95%CI (0.643, 0.815)], low preoperative oxygen saturation [OR=0.942, 95%CI (0.922, 0.962)], and longer cardiopulmonary bypass time [OR=1.85, 95%CI (1.189, 2.887)] were independent predictive factors of postoperative ASO. The predictive model had good discriminative ability (area under the curve=0.800). Conclusion The short-term poor prognosis of TGA neonatal ASO surgery is highly correlated with admission length, preoperative hypoxia, and longer extracorporeal circulation time. Early risk stratification based on these readily available clinical parameters can aid in individualized perioperative management and improve prognosis.
Objective To review the application and research progress of dexamethasone in the perioperative period of joint arthroplasty and arthroscopic surgery. Methods The relevant domestic and foreign literature in recent years was extensively reviewed. The application status and therapeutic effect of dexamethasone in the perioperative period of joint arthroplasty and arthroscopic surgery were summarized. Results Studies have shown that intravenous administration of 10-24 mg dexamethasone before or/and within 24-48 hours after operation can reduce the incidence of nausea and vomiting, and reduce the consumption of opioids in patients after hip and knee arthroplasties with high safety. The duration of nerve block during arthroscopic surgery can be prolonged by perineural injecting local anesthetics and 4-8 mg dexamethasone, but the effect of postoperative analgesia is still controversial. Conclusion Dexamethasone is widely used in joint and sports medicine. It has the effects of analgesia, antiemetic, and prolonging the time of nerve block. In the future, high-quality clinical studies on the application of dexamethasone in shoulder, elbow, and ankle arthroplasties and arthroscopic surgery are needed, and more attention should be paid to the long-term safety of dexamethasone.
In tracheal resection and reconstruction, a technically demanding, complex, and high-risk procedure, management of the anastomotic site significantly impacts postoperative outcomes and long-term quality of life. However, comprehensive studies detailing perioperative anastomotic management strategies in tracheal reconstruction remain scarce. This review summarizes perioperative management strategies for tracheal reconstruction, covering preoperative assessment, surgical techniques, and other key aspects. It also highlights future research directions and challenges, aiming to provide clinicians with a systematic guide to perioperative management in tracheal reconstruction.
The concept of enhanced recovery after surgery (ERAS) is composed of multidisciplinary, multimodal, and evidence-based approaches, providing a safe and cost-effective method for perioperative management to improve patient prognosis without increasing the incidence of complications. At present, ERAS for cardiac surgery has developed slowly. This article provides a review of the application and prospects of ERAS concept in the perioperative period of cardiac surgery. The measures for applying ERAS concept to the perioperative period of cardiac surgery are divided into three parts: preoperative, intraoperative, and postoperative. The aim is to provide information for the perioperative management of cardiac surgery patients and assist in their rapid recovery during the perioperative period.
ObjectiveTo summarize the progress of perioperative pain management in patients with lower limb vascular diseases. MethodRetrieved the literature about pain management in patients with lower limb vascular diseases both at home and abroad in recent years and reviewed the literature. ResultsLower limb vascular diseases were very common in elderly patients. Whether it was limb ischemic pain or surgery-related pain, it often increased the stress response and activation of the autonomic system, which was not conducive to the recovery of the disease. Good analgesic management was important for these patients. Perioperative pain management could be performed by intravenous analgesics, oral analgesics, local anesthesia, neuraxial anesthesia and peripheral nerve block. Acute and chronic pain should be actively managed during perioperative period. Pre-emptive analgesic strategies could be implemented in patients with severe peripheral vascular disease. ConclusionsGood perioperative analgesia management is necessary. Pain management which employes one or more analgesic methods is important in maximizing pain relief, function, and quality of life for this patient group.
ObjectiveTo explore the clinical value of soluble suppression of tumorigenesis-2 (sST2) in replacement of N-terminal fragment of the brain natriuretic peptide precursor (NT-proBNP) in cardiac function evaluation in renal failure patients after cardiac surgery.MethodsSixty patients with renal insufficiency after cardiac surgery from January 2019 to June 2019 were divided into a test group, including 34 males and 26 females, with an average age of 49-78 (63.3±4.5) years. Another 60 patients with normal renal function were divided into a control group, including 37 males and 23 females, with an average age of 53-77 (61.7±3.8) years. The perioperative left ventricular ejection fraction, cardiac troponin T, creatine kinase-MB, sST2 and NT-proBNP were compared.ResultsIn patients of the test group, the NT-proBNP level increased significantly during perioperative period, and the change range was different from other cardiac function indexes. The change of sST2 in perioperative period was similar to other cardiac function indexes, which could reflect the change degree of cardiac function after operation.ConclusionsST2 is more important to reflect the change degree of cardiac function in patients with renal dysfunction after cardiac surgery than NT-proBNP.
Objective To understand the changes of intestinal flora during perioperative period of colorectal cancer and the mechanism affecting the occurrence of postoperative anastomotic leakage, so as to improve perioperative management of patients and find possible measures to decrease the incidence rate of anastomotic leakage. Method The literature related to perioperative intestinal flora assessment, anastomotic healing, and anastomotic leakage of colorectal cancer in recent years was comprehensively searched in the CNKI, PubMed, and Embase databases and made an review. ResultsDue to the various perioperative interventions, the diversity and abundance of intestinal flora had changed after colorectal cancer surgery, and some conditional pathogenic bacteria such as Enterococcus faecalis, Pseudomonas aeruginosa, etc. increased obviously, which led to collagen degradation through the expression of bacterial collagenase or the excessive activation of matrix metalloproteinases in the host intestine, then might lead to the poor anastomotic healing and even the anastomotic leakage. ConclusionAlthough the evidence of effect of intestinal flora on anastomotic leakage mainly comes from animal experiments, it still shows the potential role of intestinal flora in the occurrence of anastomotic leakage after colorectal cancer surgery, and can be regulated by perioperative intervention, which suggests that it may provide a new strategy for prevention of anastomotic leakage.
Enhanced recovery after surgery (ERAS) is a protocol designed to improve perioperative outcomes by multidisciplinary team with evidence-based interventions. The implementation of ERAS concept has been proved to reduce postoperative complications and hospital stay. The anesthesia management under the concept of ERAS is the basis of safe and smooth ambulatory surgical protocol. This article summarizes the latest clinical evidence at home and abroad, and reviews the preoperative optimization, anesthesia mode selection, ventilation strategies, fluid management, temperature support, pain management, postoperative nausea and vomiting prevention, postoperative nutritional support, and postoperative sleep improvement in the management of anesthesia under ERAS concept, in order to provide a reference for anesthesia management in ambulatory surgery.
ObjectiveTo evaluate the effect of perioperative nebulization of ipratropium bromide on preoperative pulmonary function and incidence of postoperative pulmonary complications as well as safety in chronic obstructive pulmonary disease (COPD) patients who underwent lung resection in thoracic surgery. MethodsDuring November 18, 2013 to August 12, 2015, 192 COPD patients with a necessity of selective surgical procedures of lobectomy or right bilobectomy or segmentectomy under general anaesthesia in 10 centers were 1 : 1 randomized to an ipratropium bromide group (96 patients) and a placebo group (96 patients), to compare the effect on preoperative pulmonary function and incidence of postoperative pulmonary complications. The average age of treated patients was 62.90±6.50 years, with 168 male patients and 22 female patients. Results The demographic and baseline characteristics were well-balanced between the two groups. The adjusted mean increase of forced expiratory volume in one second (FEV1) in the ipratropium bromide group was significantly higher than that in the placebo group (169.90±29.07 mL vs. 15.00±29.35 mL, P<0.05). The perioperative use of ipratropium bromide significantly decreased incidence of postoperative pneumonia (2.6% vs. 14.1%, P<0.05). There was no ipratropium bromide related adverse event (AE) observed in this trial. ConclusionThis trial indicates that perioperative nebulization of ipratropium bromide significantly improves preoperative lung function and reduces postoperative pneumonia in COPD patients undergoing lung resection in thoracic surgery, and has good safety profile.
Objective To study the effect of perioperative nutritional support on protein metabolism and immunity in patients underwent liver transplantation. Methods A total of 80 patients who underwent liver transplantation in our hospital from March 2015 to March 2016 were collected retrospectively, and then the 80 patients were divided into control group (n=40) and observation group (n=40) according to the type of perioperative nutritional support. Patients of control group didn’t receive preoperatively nutritional support, and received total parenteral nutrition support before postoperative exhaust, then received enteral nutrition support after anal exhaust. Patients of observation group receive preoperatively nutritional support before surgery, and received parenteral nutrition and enteral nutrition support before postoperative exhaust. The several parameters about nutritional status and immune function were observed on 7 days and 14 days after liver transplantation, and comparison of the 2 group in these parameters was performed. Results On the protein metabolism, the levels of serum transferrin, prealbumin, and nitrogen balance on 14 days after liver transplantation were higher than those of other time points (before liver transplantation and 7 days after liver transplantation),P<0.05, both in control group and observation group. There was no significant difference in the levels of serum transferrin, prealbumin, and value of nitrogen balance between the 2 groups before liver transplantation (P>0.05). But on 7 days and 14 days after liver transplantation, the levels of serum transferrin, prealbumin, and value of nitrogen balance of the observation group were higher than those of control group (P<0.05). On the immunity, the total number of lymphocytes, value of IgG and CD4/CD8 on 14 days after liver transplantation, were superior to other time points (before liver transplantation and 7 days after liver transplantation),P<0.05, both in control group and observation group. There was no significant difference in the total number of lymphocytes, value of IgG and CD4/CD8 between the 2 groups before liver transplantation (P>0.05). But on 7 days and 14 days after liver transplantation, the levels of the total number of lymphocytes, value of IgG and CD4/CD8 in the observation group were superior to those of control group (P<0.05). Conclusion Perioperative nutritional support can improve the nutritional status and immune function in patients underwent liver transplantation.
