The aim was to investigate whether 2 weeks of inspiratory muscle training (IMT) could preserve respiratory muscle strength in high-risk patients referred for pulmonary resection on the suspicion of or confirmed lung cancer. Secondarily, we investigated the effect of the intervention on the incidence of postoperative pulmonary complications. The study was a single-centre, parallel-group, randomized trial with assessor blinding and intention-to-treat analysis. The intervention group (IG, n = 34) underwent 2 weeks of postoperative IMT twice daily with 2 × 30 breaths on a target intensity of 30% of maximal inspiratory pressure, in addition to standard postoperative physiotherapy. Standard physiotherapy in the control group (CG, n = 34) consisted of breathing exercises, coughing techniques and early mobilization. We measured respiratory muscle strength (maximal inspiratory/expiratory pressure, MIP/MEP), functional performance (6-min walk test), spirometry and peripheral oxygen saturation (SpO ₂ ), assessed the day before surgery and again 3–5 days and 2 weeks postoperatively. Postoperative pulmonary complications were evaluated 2 weeks after surgery. The mean age was 70 ± 8 years and 57.5% were males. Thoracotomy was performed in 48.5% ( n = 33) of cases. No effect of the intervention was found regarding MIP, MEP, lung volumes or functional performance at any time point. The overall incidence of pneumonia was 13% ( n = 9), with no significant difference between groups [IG 6% ( n = 2), CG 21% ( n = 7), P = 0.14]. An improved SpO ₂ was found in the IG on the third and fourth postoperative days (Day 3: IG 93.8 ± 3.4 vs CG 91.9 ± 4.1%, P = 0.058; Day 4: IG 93.5 ± 3.5 vs CG 91 ± 3.9%, P = 0.02). We found no association between surgical procedure (thoracotomy versus thoracoscopy) and respiratory muscle strength, which was recovered in both groups 2 weeks after surgery. Two weeks of additional postoperative IMT, compared with standard physiotherapy alone, did not preserve respiratory muscle strength but improved oxygenation in high-risk patients after lung cancer surgery. Respiratory muscle strength recovered in both groups 2 weeks after surgery. NCT01793155.

After midline sternotomy patients are instructed on activity precautions to avoid sternal wound complications. We questioned how restrictive these precautions must be, since they can lead to a postoperative decrease in quality of life. To identify mechanical stress factors causing sternal instability and infection in order to create evidence based guidelines for activity following sternotomy. Literature review. No evidence was found to support weight limitation regarding activity, as long as the upper arms are kept close to the body and activity is within a pain-free range. Avoid stretching both arms backwards at the same time (10 days); loaded activities should be done with the elbows close to the body (eight weeks); only move arms within a pain-free range; use leg rolling with counterweighing when getting in and out of bed; when coughing cross the arms in a "self-hugging" posture; supportive bra or vest is recommended when breast cup>or=D, body mass index>or=35 or frequent cough. This study provides insights into mechanical stress factors acting upon sternum and the overlying skin. RECOMMENDATIONS on activity precautions based on these finding have a patient supportive approach focusing on possibilities and not restrictions.

There is an increasing awareness that patients with acute pulmonary embolism (APE) suffer long-term consequences like fatigue, anxiety, and reduced physical capacity. However, we lack knowledge on how patients manage everyday life and physical activity following an APE. The study aimed to explore how patients experience and cope with daily life and physical activity in the first year following an APE. Semi-structured individual interviews were performed with 16 patients, 6-12 months after a first-time APE event. The methodological framework for the analysis was interpretive description. Most participants had managed to return to their daily routines at the time of the interview, although some struggled more than others. They experienced their daily life and well-being to be negatively affected by fatigue, anxious thoughts and bodily hypervigilance, and were concerned about themselves, their family, friends and life situation. In many cases, they lacked advice from health professionals. Participants used various strategies for re-engaging in everyday life and physical activities, reflecting their physical and mental resources, contextual support, and different life situation. One central theme was the challenge of coming to terms with a more vulnerable identity, and adjusting this identity to established family and work roles. Most participants had managed to resume their everyday life 6-12 months after the APE event, but were still limited in their daily activities and found it difficult to sustain a sufficient level of physical activity. They described different barriers and facilitators, which should be addressed in future rehabilitation interventions.

The need for oxygen increases with activity in patients with COPD and on long-term oxygen treatment (LTOT), leading to periods of hypoxemia, which may influence the patient’s performance. This study aimed to evaluate the effect of automated oxygen titration compared to usual fixed-dose oxygen treatment during walking on dyspnea and endurance in patients with COPD and on LTOT. In a double-blinded randomised crossover trial, 33 patients were assigned to use either automated oxygen titration or the usual fixed-dose in a random order in two walking tests. A closed-loop device, O2matic delivered a variable oxygen dose set with a target saturation of 90–94%. The patients had a home oxygen flow of (mean ± SD) 1.6 ± 0.9 L/min. At the last corresponding isotime in the endurance shuttle walk test, the patients reported dyspnea equal to median (IQR) 4 (3–6) when using automated oxygen titration and 8 (5–9) when using fixed doses, p < 0.001. The patients walked 10.9 (6.5–14.9) min with automated oxygen compared to 5.5 (3.3–7.9) min with fixed-dose, p < 0.001. Walking with automated oxygen titration had a statistically significant and clinically important effect on dyspnea. Furthermore, the patients walked for a 98% longer time when hypoxemia was reduced with a more well-matched, personalised oxygen treatment.

Respiratory deficits are common following curative intent lung cancer surgery and may reduce the patient's ability to be physically active. We evaluated the influence of surgery on pulmonary function, respiratory muscle strength and physical performance after lung resection.Pulmonary function, respiratory muscle strength (maximal inspiratory/expiratory pressure) and 6-min walk test (6MWT) were assessed pre-operatively, 2 weeks post-operatively and 6 months post-operatively in 80 patients (age 68±9 years).Video-assisted thoracoscopic surgery was performed in 58% of cases. Two weeks post-operatively, we found a significant decline in pulmonary function (forced vital capacity −0.6±0.6 L and forced expiratory volume in 1 s −0.43±0.4 L; both p<0.0001), 6MWT (−37.6±74.8 m; p<0.0001) and oxygenation (−2.9±4.7 units; p<0.001), while maximal inspiratory and maximal expiratory pressure were unaffected. At 6 months post-operatively, pulmonary function and oxygenation remained significantly decreased (p<0.001), whereas 6MWT was recovered.We conclude that lung resection has a significant short- and long-term impact on pulmonary function and oxygenation, but not on respiratory muscle strength. Future research should focus on mechanisms negatively influencing post-operative pulmonary function other than impaired respiratory muscle strength.
