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 analyze the occurrence of postoperative pulmonary complications (PPC) and the risk factors in patients with spontaneous pneumothorax who underwent micro single-port video-assisted thoracoscopic surgery (VATS).MethodsA total of 158 patients with spontaneous pneumothorax who underwent micro single-port VATS in our hospital from April 2017 to December 2019 were retrospectively included, including 99 males and 59 females, with an average age of 40.53±9.97 years. The patients were divided into a PPC group (n=21) and a non-PPC group (n=137) according to whether PPC occurred after the operation, and the risk factors for the occurrence of PPC were analyzed.ResultsAll 158 patients successfully completed the micro single-port VATS, and there was no intraoperative death. The postoperative chest tightness, chest pain, and dyspnea symptoms basically disappeared. During the postoperative period, there were 3 patients of pulmonary infection, 7 patients of atelectasis, 4 patients of pulmonary leak, 6 patients of pleural effusion, 1 patient of atelectasis and pleural effusion, and the incidence of PPC was 13.29% (21/158). Multivariate logistic regression analysis showed that lung disease [OR=32.404, 95%CI (2.717, 386.452), P=0.006], preoperative albumin level≤35 g/L [OR=14.912, 95%CI (1.719, 129.353), P=0.014], severe pleural adhesions [OR=26.023, 95%CI (3.294, 205.557), P=0.002], pain grade Ⅱ-Ⅲ 24 hours after the surgery [OR=64.024, 95%CI (3.606, 1 136.677), P=0.005] , age [OR=1.195, 95%CI (1.065, 1.342), P=0.002], intraoperative blood loss [OR=1.087, 95%CI (1.018, 1.162), P=0.013] were the risk factors for PPC after micro single-port VATS.ConclusionThere is a close relationship between PPC after micro single-port VATS and perioperative indexes in patients with spontaneous pneumothorax. Clinically, targeted prevention and treatment can be implemented according to the age, pulmonary disease, preoperative albumin level, intraoperative blood loss, degree of pleural adhesion and pain grading 24 hours after surgery.
In the past two decades, adult cardiac surgery has developed by leaps and bounds in both anesthetic techniques and surgical methods, whereas the incidence of postoperative pulmonary complications (PPCs) has not changed. Until now PPCs are still the most common complications after cardiac surgery, resulting in poor prognosis, significantly prolonged hospital stays and increased medical costs. With the promotion of the concept of enhanced recovery after surgery (ERAS), pre-rehabilitation has been becoming a basic therapy to prevent postoperative complications. Among them, preoperative inspiratory muscle training as a very potential intervention method has been widely and deeply studied. However, there is still no consensus about the definition and diagnostic criteria of PPCs around the world; and there is significant heterogeneity in preoperative inspiratory muscle training in the prevention of pulmonary complications after cardiac surgery in adults, which impedes its clinical application. This paper reviewed the definition, mechanism, and evaluation tools of PPCs, as well as the role, implementation plan and challenges of preoperative inspiratory muscle training in the prevention of PPCs in patients undergoing cardiac surgery, to provide reference for clinical application.
ObjectiveTo evaluate the association of anesthesia regime (volatile or intravenous anesthetics) with the occurrence of postoperative pulmonary complications (PPCs) in adult patients undergoing elective cardiac surgery under cardiopulmonary bypass (CPB).MethodsThe electronic medical records of 194 patients undergoing elective cardiac surgery under CPB at West China Hospital, Sichuan University between September 2018 and February 2019 were reviewed, including 92 males and 102 females with an average age of 53 years. The patients were classified into a volatile group (n=94) or a total intravenous anesthesia (TIVA) group (n=100) according to anesthesia regimen during surgery (including CPB). The primary outcome was the incidence of PPCs within first 7 d after surgery. Secondary outcomes included incidence of reintubation, duration of mechanical ventilation, ICU stay and hospital stay.ResultsThere was no significant difference in the incidence of PPCs between the two groups (RR=1.020, 95%CI 0.763-1.363, P=0.896), with an incidence of 48.9% in the volatile group and 48.0% in the TIVA group. Secondary outcomes were also found no significant difference between the two groups (P>0.05).ConclusionNo association of anesthesia regimen with the incidence of PPCs is found in adult patients undergoing elective cardiac surgery under CPB.
Objective To evaluate the effect of perioperative fluid management on postoperative pulmonary complications (PPCs) of esophagectomy, and to find out the optimal scheme for perioperative fluid administration. Methods This retrospective cohort study enrolled 75 patients with esophageal squamous cell cancer who have received esophagectomy in West China Hospital from June to December 2014. We used the Kroenke's postoperative pulmonary complications classification system to define the PPCs. Patients with PPCs of grade Ⅱ-Ⅳ were considered as PPCs group (n=13, 12 males, 1 female, age of 64.62±8.64 years), and others were considered as non-complication group (n=62, 50 males, 12 females, age of 60.55±8.73 years). Intraoperative and postoperative fluid inputs and outputs as well as clinical characteristics between groups were compared. Results Between two groups, there was a great difference in postoperative albumin infusion, intraoperative fluid administration [net input, total input, net input/kg, total input/kg, net input/(kg·h) and total input/(kg·h)] and fluid input on the first postoerative 1–3 days (total input and total input/kg). The cutoff value for total input/(kg·h) in operation and total input on the first 1–3 postoerative days was 12.07 ml/(kg·h) and 178.57 ml/kg, respectively. Conclusion The speed of fluid infusion in operation and total input on postoperative 1-3 days are most important influence factors of PPCs. The speed in operation should not exceed 12.07 ml/(kg·h) and the total input on postoperative 1-3 days should not exceed 178.57 ml/kg. Within this range, an appropriate increase in fluid volume can make patients feel better.
Objective To investigate the relationship between preoperative mean daily step counts and pulmonary complications after thoracoscopic lobectomy in elderly patients. Methods From 2018 to 2021, the elderly patients with pulmonary complications after thoracoscopic lobectomy were included. A 1∶1 propensity score matching was performed with patients without pulmonary complications. The clinical data were compared between the two groups. ResultsTotally, 100 elderly patients with pulmonary complications were enrolled, including 78 males and 22 females, aged 66.4±4.5 years. And 100 patients without pulmonary complications were matched, including 71 males and 29 females aged 66.2±5.0 years. There was no significant difference in the preoperative data between the two groups (P>0.05). Compared to the patients with pulmonary complications, the ICU stay was shorter (8.1±4.4 h vs. 12.9±7.5 h, P＜0.001), the first out-of-bed activity time was earlier (8.8±4.5 h vs. 11.2±6.1 h, P=0.002), and the tube incubation time was shorter (19.3±9.2 h vs. 22.5±9.4 h, P=0.015) in the patients wihout pulmonary complications. There was no statistical difference in other perioperative data between the two groups (P>0.05). The mean daily step counts in the pulmonary complications group were significantly less than that in the non-pulmonary complications group (4 745.5±2 190.9 steps vs. 6 821.1±2 542.0 steps, P＜0.001). The daily step counts showed an upward trend for three consecutive days in the two groups, but the difference was not significant. Conclusion The decline of preoperative mean daily step counts is related to pulmonary complications after thoracoscopic lobectomy in elderly patients. Recording daily step counts can promote preoperative active exercise training for hospitalized patients.
[Abstract]Elderly patients with lung cancer have a significantly increased risk of perioperative cardiopulmonary complications due to physiological decline, high incidence of complications and reduced surgical tolerance, which directly affects postoperative recovery and long-term survival. Although the concepts of minimally invasive surgery and enhanced recovery after surgery have improved clinical outcomes, early recognition and intervention of postoperative complications in elderly patients remains a significant challenge in the field of thoracic surgery. By integrating recent literature and clinical practice, this paper systematically analyzes the pathophysiological mechanism and risk factors of perioperative cardiopulmonary complications in elderly patients with lung cancer, and discusses individualized intervention strategies based on risk stratification and multidisciplinary team, in order to provide theoretical basis and practical guidance for optimizing perioperative management and improving postoperative prognosis in elderly patients.
Objective To evaluate the association between pressure-controlled ventilation-volume guaranteed (PCV-VG) mode and volume-controlled ventilation (VCV) mode on postoperative pulmonary complications (PPCs) in patients undergoing thoracoscopic lung resection. Methods A retrospective cohort analysis of 329 patients undergoing elective thoracoscopic lung resection in West China Hospital of Sichuan University between September 2020 and March 2021 was conducted, including 213 females and 116 males, aged 53.6±11.3 years. American Society of Anesthesiologists (ASA) grade wasⅠ-Ⅲ. The patients who received lung-protective ventilation strategy during anesthesia were divided into a PCV-VG group (n=165) and a VCV group (n=164) according to intraoperative ventilation mode. Primary outcome was the incidence of PPCs during hospitalization. Results A total of 73 (22.2%) patients developed PPCs during hospitalization. The PPCs incidence of PCV-VG and VCV was 21.8% and 22.6%, respectively (RR=0.985, 95%CI 0.569-1.611, P=0.871). Multivariate logistic regression analysis showed that there was no statistical difference in the incidence of PPCs between PCV-VG and VCV mode during hospitalization (OR=0.846, 95%CI 0.487-1.470, P=0.553). Conclusion Among patients undergoing thoracoscopic lung resection, intraoperative ventilation mode (PCV-VG or VCV) is not associated with the risk of PPCs during hospitalization.
Perioperative mechanical ventilation plays a role in lung injury and postoperative pulmonary complications, yet a consensus in the literature concerning the key clinical question of how to best provide lung protection during mechanical ventilation in surgical patients is lacking. It is necessary to develop an expert consensus on perioperative mechanical ventilation suitable for Chinese anesthesiologists to better guide clinical practice. The experts from the Anesthesia Committee of Chengdu Medical Association and the Chongqing Medical Association Anesthesiology Branch were organized by West China Hospital of Sichuan University to propose the question regarding the perioperative mechanical ventilation, and the current literature was then reviewed, and expert opinions were solicited to provide evidence-based guidance. Subsequently, the expert panel reached a consensus and formulated 28 recommendations with evidence of moderate to high quality using the modified Delphi method.
Risk prediction models for postoperative pulmonary complications (PPCs) can assist healthcare professionals in assessing the likelihood of PPCs occurring after surgery, thereby supporting rapid decision-making. This study evaluated the merits, limitations, and challenges of these models, focusing on model types, construction methods, performance, and clinical applications. The findings indicate that current risk prediction models for PPCs following lung cancer surgery demonstrate a certain level of predictive effectiveness. However, there are notable deficiencies in study design, clinical implementation, and reporting transparency. Future research should prioritize large-scale, prospective, multi-center studies that utilize multiomics approaches to ensure robust data for accurate predictions, ultimately facilitating clinical translation, adoption, and promotion.
