Since the outbreak of coronavirus disease 2019 (COVID-19), there have been numerous studies confirming that physiotherapy is an essential part of the comprehensive treatment during hospitalization and can facilitate recovery in COVID-19 patients. However, physiotherapy protocols for COVID-19 patients in intensive care units are still lacking. This article reviews the literature and incorporates practical experience around recommendations for the safe protection during physiotherapy, recommendations for evaluation criteria and intervention of physiotherapy, and future work for COVID-19 patients, so as to provide a standardized recommendation for physiotherapists working in intensive care units.
Abstract: Objective To evaluate the impact of shortterm preoperative pulmonary rehabilitation (PR) on the exercise capacity of lung cancer patients with moderate to severe chronic obstructive pulmonary disease（COPD）. Methods Between March 2009 and August 2010, 30 lung cancer patients with moderate or severe COPD were treated with preoperative comprehensive PR for two weeks in Department of Thoracic Surgery, West China Hospital. The sample was comprised of 18 males and 12 females with an average age of 62.5±7.7 years. Twelve of the patients had moderate COPD, while 18 had severe COPD. We collected information on the length of postoperative hospital stay for each patient,as well as any pulmonary complications. Results (1) The forced expiratory volume in one second (FEV1), forced expiratory volume in one second % (FEV1%), forced expiratory volume in/ forced vital capacity (FEV1/FVC),and maximal ventilatory volume (MVV) (1.30±0.30 L, 59.19±18.00 L, 47.74±1200 L, 56.63±13.00 L) values after PR were slightly better than those before PR(1.24±0.40 L, 51.89±14.00 L, 46.59±10.00 L, 49.67±13.00 L), but not significantly so(Pgt;0.05). The results for carbon monoxide diffusion capacity were similar. (2) The sixminute walking distance (before: 502.67±157.00 m, after: 594.87±116.00 m), peak expiratory flow (before: 209.33±66.00 L/min, after: 255.33±70.00 L/min), dyspnea index (Borg index) (before: 0.26±0.20, after: 0.12±0.10), and fatigue index (before:0.24±0.20, after: 0.12±0.10) all improved significantly aftercomprehensive PR (Plt;0.05). (3) All 30 patients underwent surgery, and none died during the perioperative period. Eight patients experienced cardiopulmonary complications. The average hospitalization time after surgery was 8.0±2.4 days. Conclusion Preoperative comprehensive PR appears to significantly improve exercise capacity and reduce the rate of postoperative lung complications in lung cancer, patients with lower cardiopulmonary function.
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 investigate the morbidity of postoperative pulmonary complications (PPCs) in patients after transcatheter tricuspid valve replacement (TTVR). MethodsA 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. ResultsOf 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. ConclusionPPCs 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.
ObjectiveTo investigate the safety and feasibility of early mobilization in critically ill patients with femoral catheters, and to provide reference for guiding clinical rehabilitation training. MethodsThe 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. ResultsSeventy-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. ConclusionAlthough 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.
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 impact of complete video-assisted thoracoscopic lobectomy and open lobectomy on perioperative heart rate （HR） and blood oxygen saturation （SO2） of lung cancer patients，and explore whether minimally invasive surgery can enhance postoperative recovery of lung cancer patients. Methods A total of 138 lung cancer patients were chosen from 161 consecutive patients with pulmonary diseases who were admitted to West China Hospital of Sichuan University between September 2010 and December 2011. According to different surgical approach，all the 138 lung cancer patients were divided into routine thoracotomy group （thoracotomy group，70 patients including 53 males and 17 females with their average age of 56.1±9.7 years） and complete video-assisted thoracoscopic lobectomy group （VATS group，68 patients including 46 males and 22 females with their average age of 53.4±6.5 years）. There was no statistical difference in preoperative clinical characteristics between the 2 groups. Preoperative and postoperative （1st，3rd，7th and 30th day） numeric pain rating scale （NPRS），HR and SO2 were compared between the 2 groups. Results （1） There was no statistical difference in NPRS on the 1st and 3rd postoperative day between the 2 groups （3.83±0.79 vs. 3.93±0.67， 2.88±0.59 vs. 3.03±0.71，P＞0.05），but on the 7th and 30th postoperative day，NPRS of the thoracotomy group was signi- ficantly higher than that of VAST group （1.61±0.33 vs. 1.22±0.12，1.58±0.26 vs. 1.19±0.31，P＜0.05）. （2） Postop- erative sedentary HR of both VATS group and thoracotomy group were significantly higher than preoperative levels ［（84.13±17.21） / minute vs. （73.67±10.32）/minute， （86.13 ±19.67） / minute vs. （72.24±14.21） / minute， P＜0.05］. Postoperative HR of VATS group decreased to preoperative level on the 3rd postoperative day，while postoperative HR of the thoracotomy group decreased to preoperative level on the 7th postoperative day. （3） There was no statistical difference between preoperative and postoperative （all the time points） sedentary SO2 of both VATS group and thoracotomy group （96.34 %±2.11% vs. 97.12%±2.31%，95.33%±4.13% vs. 94.93% ±4.31%，P＞0.05）.（4） The changes of HR and SO2 before and after exercise of VATS group were significantly smaller than those of the thoracotomy group on the 3rd postoperative day ［（11.11±4.81）/minute vs. （18.23±6.17）/minute，3.1%±1.2% vs. 7.4 %±2.7%，P＜0.05］ . Conclusion The impact of complete video-assisted thoracoscopic lobectomy on cardiopulmonary function is comparatively smaller，which is helpful for postoperative fast-track recovery of lung cancer 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.
