[Approaches to the pre-operative functional assessment of patients with lung cancer and preoperative rehabilitation]. / Bilan fonctionnel préopératoire du cancer bronchique et réhabilitation préopératoire.

Surgery is the best treatment for early lung cancer but requires a preoperative functional evaluation to identify patients who may be at a high risk of complications or death. Guideline algorithms include a cardiological evaluation, a cardiopulmonary assessment to calculate the predicted residual lung function, and identify patients needing exercise testing to complete the evaluation. According to most expert opinion, exercise tests have a very high predictive value of complications. However, since the publication of these guidelines, minimally-invasive surgery, sublobar resections, prehabilitation and enhanced recovery after surgery (ERAS) programmes have been developed. Implementation of these techniques and programs is associated with a decrease in postoperative mortality and complications. In addition, the current guidelines and the cut-off values they identified are based on early series of patients, and are designed to select patients before major lung resection (lobectomy-pneumonectomy) performed by thoracotomy. Therefore, after a review of the current guidelines and a brief update on prehabilitation (smoking cessation, exercise training and nutritional aspects), we will discuss the need to redefine functional criteria to select patients who will benefit from lung surgery.

Influence of Respiratory Muscle Training on Patients' Recovery after Lung Resection.

This prospective experimental study aimed to compare effects of 3 different home-based postoperative respiratory muscle training protocols - inspiratory, expiratory and combined, in the patients' postoperative recovery, regarding safety and respiratory muscle function, pulmonary function, physical fitness, physical activity (PA), dyspnoea and quality of life (QoL). Patients were divided in four groups Usual Care (UCare), inspiratory (IMT), expiratory (EMT) or combined muscle training (CombT) according to group allocation. Significant treatment*time interactions were found for maximal inspiratory pressure (MIP) (p=0.014), sedentary PA (SEDPA) (p=0.003), light PA (LIGPA) (p=0.045) and total PA (p=0.035). Improvements were observed for MIP in CombT (p=0.001), IMT (p=0.001), EMT (p=0.050). SEDPA reduced in EMT (p=0.001) and IMT (p=0.006), while LIGPA increased in both groups (p=0.001), as well as Total PA (p=0.005 and p=0.001, respectively). In UCare, CombT, and EMT, QoL improved only for Usual Activities. In conclusion, the addition of respiratory muscle training to physiotherapy usual care is safe and effective to increase MIP and contribute to improve physical activity. The CombT showed greater improvement on MIP, while IMT compared to EMT, was more effective to improve physical activity.

Effects of Transcutaneous Electrical Nerve Stimulation on Pain, Pulmonary Function, and Respiratory Muscle Strength After Posterolateral Thoracotomy: A Randomized Controlled Trial.

PURPOSE: To evaluate the effects of transcutaneous electrical nerve stimulation (TENS) compared to placebo TENS and a control group on pain, pulmonary function, respiratory muscle strength, and analgesic medications in the postoperative period of thoracotomy in an Intensive care unit (ICU). METHODS: Patients who had undergone posterolateral thoracotomy were randomly allocated to receive TENS during ICU stay, or placebo TENS, or into the control group. All groups received conventional physiotherapy. We analysed the intensity of pain, pulmonary function, respiratory muscle strength, and use of analgesia medications. Outcomes were evaluated before surgery, immediately after, 24 and 48 h after ICU admission. RESULTS: Forty-five patients were included. Regarding pain perception, there was no difference between groups (p = 0.172), but there was a significant reduction in pain intensity for patients receiving TENS after first physiotherapy session compared to baseline (4.7 ± 3.2 vs 3.3 ± 2.6; p < 0.05). All groups had a decrease in forced vital capacity (FVC) after surgery (p < 0.001). There was no difference between the groups regarding the use of analgesic medications, but a higher intake of morphine and acetaminophen were observed for the control (p = 0.037) and placebo group (p = 0.035), respectively. CONCLUSION: The use of TENS provides a little benefit of pain (in the first 12 h) but failed to demonstrate any improvement in the recovery of ICU patients after 48 h of posterolateral thoracotomy. TRIAL REGISTRATION: NCT02438241.

Multimodal analgesia using intrathecal diamorphine, and paravertebral and rectus sheath catheters are as effective as thoracic epidural for analgesia post-open two-phase esophagectomy within an enhanced recovery program.

Thoracic epidural (TE) analgesia has been the standard of care for transthoracic esophagectomy patients since the 1990s. Multimodal anesthesia using intrathecal diamorphine, local anesthetic infusion catheters (LAC) into the paravertebral space and rectus sheaths and intravenous opioid postoperatively represent an alternative option for postoperative analgesia. While TE can provide excellent pain control, it may inhibit early postoperative recovery by causing hypotension and reducing mobilization. The aim of this study is to determine whether multimodal analgesia with LAC was effective with respect to adequate pain management, and compare its impact on hypotension and mobility. Patients receiving multimodal LAC analgesia were matched using propensity score matching to patients undergoing two-phase trans-thoracic esophagectomy with a TE over a two-year period (from January 2015 to December 2016). Postoperative endpoints that had been evaluated prospectively, including pain scores on movement and at rest, inotrope or vasoconstrictor requirements, and hypotension (systolic BP < 90 mmHg), were compared between cohorts. Out of 14 patients (13 male) that received LAC were matched to a cohort of 14 patients on age, sex, and comorbidity. Mean and maximum pain scores at rest and movement on postoperative days 0 to 3 were equivalent between the groups. In both cohorts, 50% of patients had a pain score of more than 7 on at least one occasion. Fewer patients in the LAC group required vasoconstrictor infusion (LAC: 36% vs. TE: 57%, P = 0.256) to maintain blood pressure or had episodes of hypotension (LAC: 43% vs. TE: 79%, P = 0.05). The LAC group was more able to ambulate on the first postoperative day (LAC: 64% vs. TE: 43%, P = 0.14) but these differences were not statistically significant. Within the epidural cohort, three patients had interruption of epidural due to dislodgement or failure of block compared to no disruption in the multimodal local anesthesia catheters group (P = 0.05). Therefore, multimodal anesthesia using spinal diamorphine with combined paravertebral and rectus sheath local anesthetic catheters appears to provide comparable pain relief post two-phase esophagectomy and may provide more reliable and safe analgesia than the current standard of care.

Analysis of specialized nursing on respiratory functions in thoracotomy patients.

To analyze the nursing effect on the respiratory function of thoracotomy patients, sixty thoracotomy hospitalized patients were studied. The subjects were divided into a normal group (A) and an observation group (B). The patients in group A received routine nursing only, while those in group B received chest physiotherapy as well as routine nursing. Afterwards, the respiratory function indicators of the two groups were compared and a data analysis was performed. The results showed that the partial pressure of oxygen (PO2) value of the patients in group B was greater than that of the patients in group A while the partial pressure of carbon dioxide (PCO2) value in group B was smaller than that in group A, and there was a significant difference between the two groups (p less than 0.05). The vital capacity under normal circumstances and forced breathing of group B were greater than that of group A and the difference was statistically significant (p less than 0.05). The incidence of complications (atelectasis, respiratory infections, pleural effusion) was statistically significant between the two groups (p less than 0.05). The degree of autonomic respiratory dysfunction in group B was lower than that in group A, and there was a significant difference (p less than 0.05), suggesting that the respiratory function in patients receiving chest physiotherapy improved significantly.

A Home-based Exercise Intervention for Non-Small Cell Lung Cancer Patients Post-Thoracotomy.

OBJECTIVES: There are no evidenced-based rehabilitative guidelines for postsurgical non-small cell lung cancer (NSCLC) patients. This qualitative study provides evidence on the acceptability of an effective postsurgical exercise intervention targeting the self-management of cancer-related fatigue to fill this gap. DATA SOURCES: Qualitative perspective of 37 individuals randomized to a 6-week exercise program following hospital discharge post-thoracotomy for NSCLC. CONCLUSION: Postsurgical NSCLC participants found this rehabilitative exercise intervention highly acceptable because it removed traditional barriers to exercise. IMPLICATION FOR NURSING PRACTICE: A highly acceptable and effective solution for meeting the unmet rehabilitative support needs of NSCLC patients has broader implications for extension to other vulnerable, aging, deconditioned populations.

[Evolution of pain during respiratory rehabilitation after major lung resection]. / Évolution de la douleur en soins de suites et rééducation après résection pulmonaire majeure.

INTRODUCTION: Lung resection for cancer is the cause of significant postoperative pain. The aim of this study was to determine whether pulmonary rehabilitation could induce a resurgence of pain. METHODS: In 2014 and 2015, pulmonary rehabilitation was offered to all patients referred to our institution after lung resection for cancer. Patients were assessed at entry and departure for nociceptive pain, neuropathic pain (DN4), for quality of life using questionnaire EORTC QlQ-C30 and for anxiety and depression (HAD questionnaire). Pain was studied before and after the sessions of cycloergometer, gym and massages. RESULTS: During the period, 99 patients were admitted to our institution following lung resection for cancer. Medians changed during pulmonary rehabilitation from 3 to 1 for nociceptive pain (p<0.001), 3 to 3 for DN4 (NS), 50 to 67 for the quality of life score (p<0.001), 7 to 5 for the anxiety (p<0.001) and 5 to 3 for depression (p<0.0001). Pain remained stable during the sessions of cycloergometer and gym, and decreased during massage. Patients undergoing thoracotomy or video-assisted thoracic surgery evolved identically. CONCLUSION: Postoperative pulmonary rehabilitation after lung resection for cancer was not harmful. It was associated with a decrease in nociceptive pain and was without effect on neuropathic pain.

Postoperative Respiratory Exercises Reduce the Risk of Developing Pulmonary Complications in Patients Undergoing Lobectomy. / Los ejercicios respiratorios postoperatorios reducen el riesgo de complicaciones pulmonares en pacientes sometidos a lobectomía.

OBJECTIVE: To evaluate the effects of an intensive postoperative physiotherapy program focused on respiratory exercises in patients undergoing lobectomy by open thoracotomy. DESIGN: Quasi-experimental study. SETTING: Tertiary referral academic hospital. PARTICIPANTS: 208 patients undergoing lobectomy by open thoracotomy. INTERVENTIONS: Control group patients (n=102) received standard medical/nursing care, and experimental group patients (n=106) added to the standard clinical pathway a daily physiotherapy program focused on respiratory exercises until discharge. OUTCOMES: Analyzed outcomes were the frequency of postoperative pulmonary complications (PPCs) more amenable to physiotherapy (pneumonia, atelectasis and respiratory insufficiency) and length of hospital stay (LOS). RESULTS: Both groups were comparable regarding preoperative and surgical characteristics. Incidence of PPCs was 20.6% in control and 6.6% in experimental group (P=.003). Median (IQR) LOS in control group was 14 (7) days (Huber M estimator 14.21) and 12 (6) days (Huber M estimator 12.81) in experimental. Logistic regression model identified the evaluated physiotherapy program (P=.017; EXP [B] 95% CI 0.081-0.780) and % FEV1 (P=.042; EXP [B] 95% CI 0.941-0.999) as protective factors for the development of PPCs in patients undergoing lobectomy. CONCLUSIONS: Implementing a postoperative intensive physiotherapy program focused on respiratory exercises reduces the risk of PPCs and resultant LOS on patients undergoing lobectomy.

[The patient with lung cancer in intensive care]. / Le patient atteint de cancer bronchique en réanimation.

In Western countries, lung cancer (LC) is the most common cause of cancer death. It is present in 15-20% of patients admitted to the ICU with a neoplastic condition. The purpose of this article is to review the causes of admission to ICU of patients with LC, their prognosis and the results of different life-support techniques. Most studies include mixed populations of non-small cell (NSCLC) and small-cell lung cancers (SCLC). However, there is preponderance of NSCLC (70%) and LC of advanced or metastatic stages, reflecting the distribution in the general population of LC. The cause of admission of LC patients to ICU is most often of respiratory origin. The ICU mortality rate currently ranges from 13 to 47% and the hospital mortality rate from 24 to 65%. The predictors of in-hospital mortality are mainly severity scores, organ dysfunction, general condition (performance status), respiratory distress and the need for mechanical ventilation or vasopressor drugs. When considering the long-term mortality, it is the features of the cancer (presence of metastases, cancer progression) that are important predictive factors.

Potentially modifiable factors contribute to limitation in physical activity following thoracotomy and lung resection: a prospective observational study.

BACKGROUND: Early mobility is considered important in minimising pulmonary complication, length of stay (LOS) and enhancing recovery following major surgery. We aimed to observe and measure the reduction in early postoperative physical activity following major thoracic surgery, identifying any potentially limiting factors, and factors predictive of reduced activity. METHODS: Patients undergoing thoracotomy and lung resection were prospectively observed for the purposes of this study. All patients were routinely assisted to mobilise by physiotherapists from postoperative day 1, and continued daily with exercise and progression of mobility as per usual practice. Physical activity was measured with SenseWear Pro 3 armband physiologic motion sensors between postoperative day 1-4. The motion sensors recorded step count, time spent in 'sedentary'/ 'moderate' activity, and energy expenditure. Frequency of postoperative pulmonary complication (PPC) and postoperative LOS were also observed. Multivariate analyses were performed using forward stepwise logistic regression; results are displayed as odds ratio (95% confidence intervals). RESULTS: n = 99, median (interquartile range) steps 472 (908) over combined postoperative days 2/ 3, sedentary activity (< 3 METs) 99%. Less active subjects reported significantly more pain on day 2 and 3 (p = 0.013/ 0.00 respectively) (p < 0.001). On regression analysis age ≥ 75 years, predicted FEV1 < 70% and poor preoperative activity were predictive of lower postoperative activity. Factors limiting mobility on day 1 included pain and dizziness. Median LOS was longer (p = 0.013) (6 vs. 5 days) in less active patients and frequency of PPC was 20% vs 4% (p = 0.034). CONCLUSION: Physical activity following major thoracic surgery is generally very limited, with less active patients demonstrating longer LOS. Factors limiting immediate postoperative mobility were largely modifiable, some of the factors predictive of lower activity were also possibly modifiable/amenable to physiotherapy or pulmonary rehabilitation. Prompt assessment and recognition of these factors is needed in future, with timely and effective management incorporated into care pathways to maximise each patients potential to mobilise postoperatively.

The state of the art in preventing postthoracotomy pain.

Pain after thoracic surgery can be intense and prolonged. Inadequate pain management can have several detrimental effects, including increased postoperative morbidity and delayed recovery as well as occurrence of postthoracotomy syndrome. Therefore, establishing an adequate analgesic regimen for thoracic surgery is critical. Thoracic paravertebral block or thoracic epidural analgesia is recommended as the first-choice therapies for postthoracotomy analgesia. When these techniques are either contraindicated or not possible, intercostal analgesia or intrathecal opioids are recommended. These techniques should be combined with nonopioid analgesics, such as acetaminophen, nonsteroidal anti-inflammatory drugs, or cyclooxygenase-2-specific inhibitors, administered on a regular "round-the-clock" basis, with opioids used as "rescue" analgesics. Finally, the integration of multimodal analgesia techniques with multidisciplinary rehabilitation program can enhance recovery, reduce hospital stay, and facilitate early convalescence.

A survey of physiotherapeutic provision for patients undergoing thoracic surgery in the U.K.

OBJECTIVES: Evaluation of physiotherapeutic provision for patients undergoing open thoracotomy and lung surgery in the U.K. Timing of physiotherapy, modalities used and factors influencing practice were also investigated. DESIGN: Survey. SETTING: Tertiary centres performing thoracic surgery. PARTICIPANTS: Forty U.K. centres were identified, and senior physiotherapists were invited to participate. METHODS: A postal survey was distributed to identified centres in August 2008, with further follow-up of non-responders. This was adapted from a similar study conducted in Australia and New Zealand. RESULTS: Thirty-one responses were received (78%). Pre-operative physiotherapy was provided by 87% of respondents: 10% provided physiotherapy for all patients and 77% only provided physiotherapy for high-risk patients. Pre-operative pulmonary rehabilitation was reported in 13% of centres. Postoperative physiotherapeutic assessment was undertaken routinely by 97% of respondents: 81% provided physiotherapy to all patients, and 16% only provided physiotherapy when a specific problem was identified. The treatments given were relatively standardised. The provision of physiotherapy following hospital discharge was generally very sparse. CONCLUSION: This study provides a guide for physiotherapists working with patients undergoing thoracic surgery to use to compare their current practices. Postoperative physiotherapy is provided extensively to UK patients undergoing open thoracotomy. However, pre-operative provision is more variable and is mainly provided for high-risk patients. Despite the subsequent publication of pre- and postoperative pulmonary rehabilitation studies, UK physiotherapy practice remained similar to that reported in Australia and New Zealand. Further research in this field is necessary to investigate the role of pre-operative physiotherapy, the role of pre- and postoperative pulmonary rehabilitation, and the effectiveness of routine postoperative physiotherapy.

[The endoscopic operations by solid thoracic tumors in children].

20 patients were operated thoracoscopically on the cause of the solid tumors of the pleural cavity. Patients were aged from 1 day of life to 17 years. Minimal size of the tumor was 3.1×3.5×4.0 sm; maximal 10×10×20 sm. The control group was created of 22 children with thoracic tumors, operated via thoracotomy. The postoperative period and outcomes were statistically better among patients, treated thoracoscopically.

Subjective and objective assessment of quality of life after chest wall resection.

OBJECTIVE: To date, quality of life (QoL) after extensive chest wall resection is not known. This study analyses QoL in long-term survivors after extensive resection. METHODS: Retrospective analysis of 51 patients operated for non-small-cell lung cancer (NSCLC)/mediastinal tumour invading the chest wall, primary/secondary chest wall tumours. QoL and functional status of long-term survivors (>36 months) were studied using Borg scale, Mahler dyspnoea index, Functional Autonomy Measuring System (SMAF) and 36-item Short Form Health Survey (SF-36) questionnaire. Out of the 51 patients, pulmonary function tests were available before and after resection in 24 patients and were subjected to analysis. RESULTS: Five-year survival was 50%, 26 patients survived>36 months. At follow-up, 22/28 deaths were cancer related. Compared to baseline, the reduction of flow expiratory volume in 1s (FEV1) and forced vital capacity (FVC) were 18% and 15%, respectively (p<0.001). The QoL study included 23 long-term survivors. A moderate/severe dyspnoea was present in 5/23 patients (21%). The SF-36 questionnaire revealed that, compared to controls, patients with chest wall resection experienced impaired QoL in physical functioning, in role physical, in body pain, in social functioning and in mental health. Objective measurements of pulmonary function correlated poorly with QoL, whereas subjective assessment of dyspnoea was significantly associated with QoL. CONCLUSIONS: This study shows that long-term survivors after extensive chest wall resection experienced moderate impairments in several QoL subscales. As previously reported in patients after pulmonary resection, subjective assessment such as dyspnoea correlated well with patient-perceived QoL.

Evaluation of an early exercise intervention after thoracotomy for non-small cell lung cancer (NSCLC), effects on quality of life, muscle strength and exercise tolerance: randomised controlled trial.

Deterioration in exercise tolerance and impairment in quality of life (QoL) are common consequences of lobectomy. This study evaluates additional exercise and strength training after lung resection on QoL, exercise tolerance and muscle strength. Fifty-three (28 male) patients attending thoracotomy for lung cancer, mean age, range 64 (32-82) years; mean pack years (SD) 31.9 (26.8); BMI 25.6 (4.2); FEV1 2.0 (0.7) l were randomised to control (usual care) or intervention (twice daily training plus usual care). After discharge the intervention group received monthly home visits and weekly telephone calls, the control group received monthly telephone calls up to 12 weeks. Assessment pre-operatively, 5 day and 12 weeks post-operatively consisted of quadriceps strength using magnetic stimulation, 6 Minute Walking Distance (6MWD) and QoL-EORTC-QLQ-LC13. QoL was unchanged over 12 weeks; 6MWD showed significant deterioration at 5 days post-operatively compared with pre-operatively, mean difference (SD)-131.6 (101.8) m and -128.0 (90.7) m in active and control groups respectively (p=0.89 between groups) which returned to pre-operative levels by 12 weeks in both groups. Quadriceps strength over the 5 day in-patient period showed a decrease of -8.3 (11.3) kg in the control group compared to increase of 4.0 (21.2) kg in the intervention group (p=0.04 between groups). Strength training after thoracotomy successfully prevented the fall in quadriceps strength seen in controls, however, there was no effect on 6MWD or QoL. 6MWD returned to pre-operative levels by 12 weeks regardless of additional support offered.

Prospective, randomized, controlled trial of thoracic epidural or patient-controlled opiate analgesia on perioperative quality of life.

BACKGROUND: Perioperative epidural analgesia provides continuous pain control and may have advantages over parenteral opiate administration. This study assessed the impact of epidural analgesia on quality of life (QOL) of patients undergoing major surgery. METHODS: Sixty patients undergoing thoracic or thoraco-abdominal surgery were studied prospectively. Patients were randomly assigned to receive either thoracic epidural analgesia or patient-controlled i.v. opiate analgesia (PCA) after operation. Visual analogue pain and sedation scores were recorded for the period of the study. QOL health surveys at 24 h (SF-8 acute form) and at 1 week (SF-36) were recorded. Results were examined by uni- and multivariate analyses corrected for the effect of multiple comparisons. RESULTS: Mean pain scores were significantly lower in the epidural group at most time points. Physical and mental scores in the epidural group were significantly better than the PCA group for both SF-8 and SF-36 QOL health surveys (P<0.001). CONCLUSIONS: Epidural analgesia with local anaesthetic and opioid improves QOL and delivers better analgesia compared with PCA in patients undergoing major thoraco-abdominal surgery.

Influence of gender on quality of life after lung surgery.

BACKGROUND: Possible differences in quality of life between men and women after lung surgery needs further study. METHODS: We performed a prospective, population-based cohort study to analyse health-related quality of life before and 6 months after lung surgery. The aim of the study was to compare the changes in quality of life in men and women undergoing lung surgery. The main outcome measures were fractional change in the physical and mental component summary scores of Short Form-36. RESULTS: A baseline Short Form-36 questionnaire was completed by 130 men and 119 women. Baseline characteristics and operative data were comparable between groups. The response rate at 6 months was 82% in men and 86% in women (p=0.47). Prior to surgery, similar impairments were found in the mental domain compared to a matched reference population in both men (42.3 vs 51.5, p<0.001) and women (36.4 vs 49.8, p<0.001). At 6 months, the physical domain was significantly worse than preoperatively in both men (45.2 vs 40.5, p<0.001) and women (46.1 vs 39.5, p<0.001). There was no significant difference in the fractional change in the physical (-14% vs -13%, p=0.85) or mental (1.3% vs 11%, p=0.09) component summary scores between men and women. CONCLUSIONS: We found no evidence for a sex-associated difference in quality of life after lung surgery. Both men and women experience significant impairment in both physical and mental aspects of quality of life 6 months after lung surgery compared with the normal population.

["Fast-track" rehabilitation in thoracic surgery. First experiences with a multimodal, interdisciplinary, and proven perioperative treatment course]. / "Fast-track-Rehabilitation" in der Thoraxchirurgie. Erste Erfahrungen mit einem interdisziplinären, multimodalen, beweisbegründeten und perioperativen Behandlungspfad.

OBJECTIVES: "Fast-track" rehabilitation is a multimodal perioperative treatment concept for accelerating postoperative recovery which has been already used successfully in visceral surgery. Of its use in thoracic surgery however, almost no data exist and the relevance of this concept for pulmonary operations is unknown. PATIENTS AND METHODS: In this prospective study we examined a new perioperative fast-track treatment concept for thoracic surgery and evaluated the results. This program employs detailed information of patients, intensive perioperative respiratory therapy, thoracic peridural analgesia, forced mobilization, and an early start of postoperative normal food intake. RESULTS: Fifty consecutive patients with benign or malignant diseases of the lung aged an average of 64 years (range 22-78) were operated on thoracoscopically (n=15) or with thoracotomy (n=35) and treated perioperatively using the fast-track program. All patients were mobilized beginning 4 h postoperatively and had normal food. The incidence of general postoperative complications was 0% in this study. Postoperative stay lasted 4.5 days (range 1.5-28.5). There was no increase in surgical complications, and 6% of the patients were readmitted. The patients' acceptance of this concept was high. CONCLUSION: Fast-track rehabilitation resulted in a decreased rate of general complications and accelerated rehabilitation in thoracic surgery.
