With the increasing incidence of lung cancer in the elderly, how to improve the quality and speed of postoperative recovery on the basis of ensuring the therapeutic effect has become an important issue in surgical management. The postoperative recovery process of elderly patients with lung cancer shows higher complexity and challenge due to their unique frailty, comorbidity burden and treatment response. This article will focus on the postoperative rehabilitation strategy, systematically sort out the physiological, pathological and treatment response characteristics of postoperative recovery in elderly patients with lung cancer, propose five postoperative rehabilitation intervention modules based on the enhanced recovery after surgery concept, and further integrate the three challenges of insufficient compliance, research heterogeneity and health economic barriers, and propose a breakthrough method with precise rehabilitation and digital management as the core, providing theoretical support and practical guidance for the optimization and implementation of postoperative rehabilitation programs for elderly patients with lung cancer.

Aortic dissection is a serious cardiovascular disease characterized by acute onset and high mortality rates. Although advancements in surgical techniques and anesthesia methods have significantly reduced surgical mortality, postoperative complications, particularly pulmonary complications, remain a challenge for the recovery of patients with aortic dissection. Existing studies indicate that respiratory rehabilitation plays a crucial role in preventing and alleviating postoperative pulmonary complications, and its application is gradually expanding. However, current understanding of respiratory rehabilitation treatment for patients with aortic dissection is still insufficient, and there is a lack of standardized protocols in clinical practice. This article aims to review the existing research evidence, comprehensively analyze common pulmonary complications after aortic dissection surgery, their pathogenesis, the latest advancements in perioperative respiratory rehabilitation, and the main challenges faced, in order to provide references for clinical practice and future research.

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.

Objective    To investigate the safety and feasibility of early mobilization in critically ill patients with femoral catheters, and to provide reference for guiding clinical rehabilitation training. Methods    The literature on the safety and feasibility of early mobilization in critically ill patients with femoral catheters included in PubMed, EMbase, OVID, Springer-link, Wiley Online Library, and Web of Science up to June 2021 was searched, and relevant data were extracted for analysis. Results    Seventy-two papers were initially screened, and 12 papers that met the criteria were finally included, covering 1 056 patients, and 489 patients had femoral catheters. Patients underwent 6 495 sessions of physical therapy, and a total of 62 patients had adverse events, including 14 (2.86%, 14/489) patients with catheter-related adverse events. Conclusion    Although early mobilization in critically ill patients with femoral catheters may lead to adverse catheter-related events, the incidence is low. Therefore, the associated risks and benefits should be weighed in clinical practice, and femoral catheter is not recommended as a contraindication for early mobilization in critically ill patients.

Patients with acute heart failure (AHF) often experience dyspnea, and monitoring and quantifying their breathing patterns can provide reference information for disease and prognosis assessment. In this study, 39 AHF patients and 24 healthy subjects were included. Nighttime chest-abdominal respiratory signals were collected using wearable devices, and the differences in nocturnal breathing patterns between the two groups were quantitatively analyzed. Compared with the healthy group, the AHF group showed a higher mean breathing rate (BR_mean) [(21.03 ± 3.84) beat/min vs. (15.95 ± 3.08) beat/min, P < 0.001], and larger R_RSBI_cv [70.96% (54.34%-104.28)% vs. 58.48% (45.34%-65.95)%, P = 0.005], greater AB_ratio_cv [(22.52 ± 7.14)% vs. (17.10 ± 6.83)%, P = 0.004], and smaller SampEn (0.67 ± 0.37 vs. 1.01 ± 0.29, P < 0.001). Additionally, the mean inspiratory time (TI_mean) and expiration time (TE_mean) were shorter, TI_cv and TE_cv were greater. Furthermore, the LBI_cv was greater, while SD1 and SD2 on the Poincare plot were larger in the AHF group, all of which showed statistically significant differences. Logistic regression calibration revealed that the TI_mean reduction was a risk factor for AHF. The BR_ mean demonstrated the strongest ability to distinguish between the two groups, with an area under the curve (AUC) of 0.846. Parameters such as breathing period, amplitude, coordination, and nonlinear parameters effectively quantify abnormal breathing patterns in AHF patients. Specifically, the reduction in TI_mean serves as a risk factor for AHF, while the BR_mean distinguishes between the two groups. These findings have the potential to provide new information for the assessment of AHF patients.

In recent years, wearable devices have seen a booming development, and the integration of wearable devices with clinical settings is an important direction in the development of wearable devices. The purpose of this study is to establish a prediction model for postoperative pulmonary complications (PPCs) by continuously monitoring respiratory physiological parameters of cardiac valve surgery patients during the preoperative 6-Minute Walk Test (6MWT) with a wearable device. By enrolling 53 patients with cardiac valve diseases in the Department of Cardiovascular Surgery, West China Hospital, Sichuan University, the grouping was based on the presence or absence of PPCs in the postoperative period. The 6MWT continuous respiratory physiological parameters collected by the SensEcho wearable device were analyzed, and the group differences in respiratory parameters and oxygen saturation parameters were calculated, and a prediction model was constructed. The results showed that continuous monitoring of respiratory physiological parameters in 6MWT using a wearable device had a better predictive trend for PPCs in cardiac valve surgery patients, providing a novel reference model for integrating wearable devices with the clinic.

Objective    To investigate the morbidity of postoperative pulmonary complications (PPCs) in patients after transcatheter tricuspid valve replacement (TTVR). Methods    A prospective cohort study enrolled 19 patients who were diagnosed with severe or greater tricuspid regurgitation in West China Hospital from October 11, 2020 to March 1, 2021, and would receive TTVR using LuX-valve for valve replacement. The patients were divided into a PPCs group and a non-PPCs group according to the presence of PPCs. The incidence of PPCs after tricuspid valve intervention between the two groups was compared. Results    Of 19 patients diagnosed with severe or greater tricuspid regurgitation registered in the database, 17 met the inclusion criteria, including 15 females and 2 males, with a mean age of 68.4±8.0 years. PPCs occurred in 9 of 17 (52.9%) patients. At discharge, compared with the non-PPCs group, the PPCs group had a longer postoperative hospital stay [11.0 (10.0, 17.0) d vs. 7.5 (7.0, 8.0) d, P=0.01], longer ICU stay [72.0 (45.5, 95.0) h vs. 20.5 (16.0, 22.8) h, P<0.01], and more hospital cost [74.3 (65.9, 98.3) thousand yuan vs. 52.6 (44.2, 57.4) thousand yuan, P<0.01]. At 30 days of follow-up, the PPCs group was found that the rate of New York Heart Association cardiac function≥class Ⅲ (66.7% vs. 12.5%, P<0.01) was higher, the six-minute walk distance (170.2±169.3 m vs. 377.9±80.5 m, P<0.01) was shorter and Kansas City Cardiomyopathy Questionnaire heart failure score (40.9±31.2 vs. 80.4±5.8, P<0.01) was less than those of the non-PPCs group. Conclusion    PPCs are common in the patients undergoing TTVR and severely affect patients' cardiac function, exercise function and quality-of-life recovery. Proactive preoperative intervention as well as early postoperative rehabilitation management should be provided to those at high risk of PPCs.

Tricuspid valve, also known as "forgotten valve" because of the high natural and surgical mortality. Transcatheter tricuspid valve replacement is an innovative surgical method to treat tricuspid regurgitation, which improves the prognosis of patients and is gradually being popularized in clinics. However, postoperative pulmonary complications are still the main causes affecting the rapid recovery and death. More and more medical experts begin to use preoperative inspiratory muscle training to reduce postoperative pulmonary complications and improve the quality of life of patients after cardiac surgery. However, there was no report on the effect of preoperative inspiratory muscle training on pulmonary complications after transcatheter tricuspid valve replacement. Therefore, for the first time, we boldly speculate that inspiratory muscle training can reduce pulmonary complications after transcatheter tricuspid valve replacement, and put forward suggestions for its treatment mechanism and strategy. But this rehabilitation intervention lacks practical clinical research. Unknown challenges may also be encountered, which may be a new research direction.
