Effects of Inspiratory Muscle Training Using an Electronic Device on Patients Undergoing Cardiac Surgery: A Randomized Controlled Trial

Abstract Background Cardiac surgery causes pathophysiological changes that favor the occurrence of pulmonary and functional complications. Objective To investigate the effects of inspiratory muscle training (IMT) with an electronic device on patients undergoing cardiac surgery. Methods A randomized controlled trial was conducted with 30 adult patients undergoing elective cardiac surgery. A control group (CG) received conventional physical therapy care, and an intervention group (IG) received IMT using the POWERbreathe K5® electronic device. Two daily sessions of physical therapy were performed at the intensive care unit and one daily session at the ward until the sixth postoperative day. The following variables were measured preoperatively and on the sixth postoperative day, in both groups: inspiratory muscle strength, dynamic inspiratory muscle strength, and peak inspiratory flow. Data distribution was evaluated by the Shapiro-Wilk test. Analysis of variance was used, and the results were considered statistically significant when p < 0.05. Results Maximal inspiratory pressure (71.7 ± 17.1 cmH2O vs 63.3 ± 21.3 cmH2O; p = 0.11], S-index (52.61 ± 18.61 vs 51.08 ± 20.71), and peak inspiratory flow [(2.94 ± 1.09 vs 2.79 ± 1.26)] were maintained in the IG but had a significant reduction in the CG. Conclusion IMT performed with an electronic device was effective at maintaining inspiratory muscle strength, dynamic inspiratory muscle strength, and peak inspiratory flow when compared to conventional physical therapy.

Prehabilitation of the Thoracic Surgery Patient.

Outcomes after thoracic surgery are better predicted by preoperative evaluation of patients' physiologic reserve (also known as personal biologic age rather than chronologic age), using validated assessment tools in multidisciplinary collaboration with geriatricians. Targetable risk factors should be identified, and methods should be utilized to minimize these risks. Prehabilitation has been validated as a tool to increase functional and nutritional status of patients undergoing surgery in other specialties and improve outcomes. Although research is still limited in thoracic surgery, early results are promising.

Enhanced Recovery After Thoracic Surgery.

Enhanced recovery pathways (ERPs), used across multiple surgical subspecialties, is a multidisciplinary delivery of perioperative care designed to lessen the psychological stress of patients undergoing surgery. Thoracic ERP has been implemented but is not widespread, and variations exist between programs. Evidence of the benefit of thoracic ERP is emerging. This article presents common components of a thoracic surgery ERP and reviews contemporary outcomes.

Enhanced Recovery after Thoracic Surgery.

Enhanced recovery programs (ERPs) aim to reduce psychological and physiological stress related to surgery, and minimize opioid use. This article describes the tenets of enhanced recovery, the guidelines for ERP in lung surgery, and the University of Virginia experience with developing and implementing a program. The impact of these strategies on short-term patient outcomes and potential long-term benefits including influence on lung cancer-specific outcomes are reviewed. The opioid crisis is of utmost importance; this article will explore how ERPs may be a mitigating factor.

Effects of dexmedetomidine on post-operative recovery and mental status in patients receiving robotic-assisted thoracic surgery.

BACKGROUND: This study aimed to investigate the effects of dexmedetomidine on the post-operative recovery and mental status in patients receiving robotic-assisted thoracic surgery (RATS). METHODS: One hundred patients who received selective RATS under general anesthesia were recruited and assigned into control group (C) and dexmedetomidine group (D). The anesthesia induction and maintenance were consistent between groups. Midazolam, sufentanil, propofol and rocuronium were intravenously injected for anesthesia induction, followed by mechanical ventilation after endotracheal intubation. Sevoflurane inhalation at a minimum alveolar concentration (MAC) of 0.5 was administered, propofol and remifentanil were intravenously injected to maintain the bispectral index (BIS) at 40-60, and rocuronium was intravenously injected once every 30 min. In the D group, dexmedetomidine was intravenously injected after endotracheal intubation, and then it was injected before the end of surgery. In the C group, normal saline of equal volume was injected. The hemodynamic parameters, blood loss, urine volume, time of surgery, time of anesthesia, total dose of propofol, time of thoracic tube indwelling, hospital stay and pulmonary complications were recorded; blood gas analysis was performed after extubation; the QoR-15 and mini-mental state examination (MMSE) questionnaires were employed for the assessment of mental status at 1 and 3 days after surgery. RESULTS: The mean arterial pressure (MAP), heart rate (HR) and brain oxygenation were similar between groups at different time points (P>0.05). There were no significant differences in the operation time, time of anesthesia and intra-operative urine volume between groups. As compared to the C group, the blood loss and dose of propofol reduced significantly (P<0.05). After extubation, the respiratory frequency reduced and PaO2 increased markedly (P<0.05). After surgery, the time of thoracic tube indwelling and hospital stay reduced dramatically in the D group as compared to the C group (P<0.05). The QoR-15 score and MMSE score in the D group were markedly higher than in the C group (P<0.05). CONCLUSIONS: Dexmedetomidine can improve the post-operative recovery and mental status after RATS.

Return to work after surgical treatment for malignant pleural mesothelioma: report of a case.

We report the case of a 56-year-old woman who underwent pleural biopsy to identify the cause of the right pleural effusion. The pathological diagnosis was epithelial malignant pleural mesothelioma. The patient worked as a junior high school teacher and strongly hoped for continuing work. Thus, we performed pleurectomy/decortication (P/D) as a curative surgery. The operative findings showed pleural thickening that in the lower lobe of the lung. Thus, peeling of the lower lobe was performed. Pleural biopsy was only performed on the upper and middle lobes. As a result, the operation was limited P/D. The pathological findings showed a small number of mesothelioma cells in the upper and middle lobes. The patient received four courses of cisplatin plus pemetrexed systemic chemotherapy after surgery. Continuous maintenance chemotherapy using pemetrexed has been performed until the time of writing. At present, she has continued her work for 6 years after the operation and has extended her retirement age without recurrence.

Exercise prehabilitation in elective intra-cavity surgery: A role within the ERAS pathway? A narrative review.

The Enhanced Recovery after Surgery (ERAS) model integrates several elements of perioperative care into a standardised clinical pathway for surgical patients. ERAS programmes aim to reduce the rate of complications, improve surgical recovery, and limit postoperative length of hospital stay (LOHS). One area of growing interest that is not currently included within ERAS protocols is the use of exercise prehabilitation (PREHAB) interventions. PREHAB refers to the systematic process of improving functional capacity of the patient to withstand the upcoming physiological stress of surgery. A number of recent systematic reviews have examined the role of PREHAB prior to elective intra-cavity surgery. However, the results have been conflicting and a definitive conclusion has not been obtained. Furthermore, a summary of the research area focussing exclusively on the therapeutic potential of exercise prior to intra-cavity surgery is yet to be undertaken. Clarification is required to better inform perioperative care and advance the research field. Therefore, this "review of reviews" provides a critical overview of currently available evidence on the effect of exercise PREHAB in patients undergoing i) coronary artery bypass graft surgery (CABG), ii) lung resection surgery, and iii) gastrointestinal and colorectal surgery. We discuss the findings of systematic reviews and meta-analyses and supplement these with recently published clinical trials. This article summarises the research findings and identifies pertinent gaps in the research area that warrant further investigation. Finally, studies are conceptually synthesised to discuss the feasibility of PREHAB in clinical practice and its potential role within the ERAS pathway.

Cold forced open-water swimming: a natural intervention to improve postoperative pain and mobilisation outcomes?

Postoperative neuropathic pain exacerbated by movement is poorly understood and difficult to treat but a relatively common complication of surgical procedures such as endoscopic thoracic sympathectomy. Here, we describe a case of unexpected, immediate, complete and sustained remission of postoperative intercostal neuralgia after the patient engaged in an open-water swim in markedly cold conditions. Though an incidental chance association is possible, the clear temporal proximity linking the swim with pain remission makes a causal relationship possible. We discuss plausible mechanisms that may underlie the relationship and discuss the potential implications for postoperative pain management and patient-centred mobilisation. We recommend further evaluation of cold forced open-water swimming as a mobility-pain provocation challenge to see if the observed unexpectedly positive outcome can be replicated. With the poor response to traditional management, there is a need for novel, curative interventions for postoperative neuropathic pain and associated impaired mobility.

Healthcare professionals' views of the enhanced recovery after surgery programme: a qualitative investigation.

BACKGROUND: The Enhanced Recovery After Surgery (ERAS) programme is an approach to the perioperative care of patients which aims to improve outcomes and speed up recovery after surgery. Although the evidence base appears strong for this programme, the implementation of ERAS has been slow. This study aimed to gain an understanding of the facilitating factors and challenges of implementing the programme with a view to providing additional contextual information to aid implementation. The study had a particular focus on the nutritional elements as these have been highlighted as important. METHODS: The study employed qualitative research methods, guided by the Normalisation Process Theory (NPT) to explore the experiences and opinions of 26 healthcare professionals from a range of disciplines implementing the programme. RESULTS: This study identified facilitating factors to the implementation of ERAS: alignment with evidence based practice, standardising practice, drawing on the evidence base of other specialties, leadership, teamwork, ERAS meetings, patient involvement and education, a pre-operative assessment unit, staff education, resources attached to obtaining The Commissioning for Quality and Innovation (CQUIN) money, the ward layout, data collection and feedback, and adapting the care pathway. A number of implementation challenges were also identified: resistance to change, standardisation affecting personalised patient care, the buy-in of relevant stakeholders, keeping ERAS visible, information provision to patients, resources, palatability of nutritional drinks, aligning different ward cultures, patients going to non-ERAS departments, spreading the programme within the hospital, differences in health issue, and utilising a segmental approach.  CONCLUSIONS: The findings presented here provide useful contextual information from diverse surgical specialties to inform healthcare providers when implementing ERAS in practice. Addressing the challenges and utilising the facilitating factors identified in this study, could speed up the rate at which ERAS is adopted, implemented and embedded.

[Respiratory Rehabilitation in Patients after Surgical Treatments in the Thoracic Region].

We assessed whether respiratory physiotherapy and kinesiotherapy as the major therapies of respiratory rehabilitation in the early stage after surgical treatments in the thoracic region was helpful to return daily life or not. Respiratory rehabilitation program in our hospital was achieved in 612 patients after surgery. It is confirmed that respiratory rehabilitation lead to prevention of complications, recovery of activities of daily living, and early discharge from hospital.

Development and evaluation of an "Interdisciplinary Postoperative Support Program" in outpatient clinics after thoracic esophagectomy.

BACKGROUND: To support patients discharged from the hospital after surgery, we launched an "Interdisciplinary Postoperative Support Program" in outpatient clinics for patients who were discharged within 1 month after thoracic esophagectomy and their families. We introduce our program and clarify the patient's physical and psychologic status by analyzing the questionnaire provided from this program. MATERIALS AND METHODS: From August 2014 to January 2015, we conducted the Interdisciplinary Postoperative Support Program every month. Thus, questionnaires regarding physical and psychologic symptoms as well as the meaningfulness of the program were obtained from 59 patients and prospectively analyzed. RESULTS: We obtained valid responses from 48 patients (81.4%). Frequent postoperative difficulties included dysphagia (50%) and decreased physical strength (39.5%). Oral intake decreased to half (55.3%) and one-fourth (25.5%) of that before esophagectomy. Frequent requests made by patients to medical staff included explanations of the postoperative symptoms (97.9%), further information on the treatments of esophageal cancer (93.8%), and the typical postoperative course experienced by other patients (76.6%). A higher percentage of positive comments were obtained regarding the management of symptoms (87.8%) and optimal access to the consultations (78.9%). The incidences of unscheduled outpatient visits were 4.1% and 14.0%, respectively, under conditions with and without this postoperative program (P = 0.03). CONCLUSION: We found that our program could provide appropriate information with higher levels of satisfaction after thoracic esophagectomy. Further investigations regarding longer periods of physical and psychologic symptoms, as well as the needs of patients and their families should be conducted to augment our program.

[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.

The effect of early mobilization protocols on postoperative outcomes following abdominal and thoracic surgery: A systematic review.

BACKGROUND: Early mobilization is considered an important element of postoperative care; however, how best to implement this intervention in clinical practice is unknown. This systematic review summarizes the evidence regarding the impact of specific early mobilization protocols on postoperative outcomes after abdominal and thoracic surgery. METHOD: The review was performed according to PRISMA guidelines. We searched 8 electronic databases to identify studies comparing patients receiving a specific protocol of early mobilization to a control group. Methodologic quality was assessed using the Downs and Black tool. RESULTS: Four studies in abdominal surgery (3 randomized controlled trials [RCTs] and 1 observational prospective study) and 4 studies in thoracic surgery (3 RCTs and 1 observational retrospective study) were identified. None of the 5 studies evaluating postoperative complications reported differences between groups. One of 4 studies evaluating duration of stay reported a significant decrease in the intervention group. One of 3 studies evaluating gastrointestinal function reported differences in favor of the intervention group. One of 4 studies evaluating performance-based outcomes reported differences in favor of the intervention group. One of 5 studies evaluating patient-reported outcomes reported differences in favor of the intervention group. Overall methodologic quality was poor. CONCLUSION: Few comparative studies have evaluated the impact of early mobilization protocols on outcomes after abdominal and thoracic surgery. The quality of these studies was poor and results were conflicting. Although bed rest is harmful, there is little available evidence to guide clinicians in effective early mobilization protocols that increase mobilization and improve outcomes.

Discharge of thoracic patients on portable digital suction: Is it cost-effective?

OBJECTIVES: A portable suction drainage device for patients undergoing thoracic surgical procedures was introduced into our service in January 2010. Patients who met strict discharge criteria were allowed to continue their treatment at home with the device. They were monitored in a designated follow-up clinic. Data were collected to identify the impact of this service in relation to the duration of follow-up required, bed-days saved, and potential cost/benefits. METHODS: All patients who underwent a thoracic procedure from March 2012 to April 2014 and required suction postoperatively for air leak were included in the study. Patients were identified as suitable according to the discharge criteria. Data regarding patient demographics were collected prospectively on the thoracic database, and data on the drainage device were logged in a specific data sheet. Visits to the follow-up clinic were also recorded. RESULTS: During the study period, 50 patients stayed a total 1125 days on the portable suction system. Twenty were discharged home, equating to 772 bed-days saved (GBP 270,000 cost-saving). Clinic attendance totalled 162 visits (GBP 24,300 cost reimbursement for attendance). Six (30%) patients were readmitted on 9 occasions due to device malfunction or inability to cope at home. CONCLUSION: Careful identification of patients suitable for discharge with a portable suction device achieved a significant cost-saving and freed hospital beds, thus allowing increased surgical activity. Patients were also able to be cared for within their home environment and maintain their quality of life.

Recovery of deambulation after cardiothoracic surgery: a single center experience.

BACKGROUND: Surgical procedure and postoperative bed rest lead to musculoskeletal system alterations with a possibility of new walking dependence of patients who undergo cardiothoracic surgery, which is sometimes associated with prolonged hospitalization and increased health expenditure. AIM: The aim of this study was to assess the postoperative motor disability in inpatients admitted to the cardiothoracic surgical ward, and the results of customized rehabilitation in terms of recovery of postural changes and walking capacity with respect to the preoperative condition and destination after discharge. DESIGN: A prospective observational study was conducted. SETTING AND POPULATION: Four hundred seventeen inpatients, who had undergone cardiothoracic surgery, were enrolled between March 2011 and January 2012 in a Hospital Unit of Cardiothoracic Surgery. METHODS: A computerized system was used to collect data about ambulation at home, type and number of rehabilitation sessions proposed, ambulation at discharge, destination after discharge from ward of origin. All patients, who give their consent, undergone rehabilitative treatment on the ward of origin with an expert physiotherapist. RESULTS: Three hundred seventy-five inpatients were examined in Cardiac Surgery. One patient (0.26%) refused rehabilitative treatment. Two patients (0.53%) died. At the time of discharge 236 (74.45%) patients had recovered the ability to walk independently. After discharge 87.64% of patients was transferred to a specialist ward for intensive rehabilitation. Forty-two inpatients were enrolled in thoracic surgery. Two patients died whilst in hospital. At the time of discharge, 36 patients (94.73%) were able to walk independently. After discharge 80% of patients returned home. CONCLUSION: In our study, the application of an early and simple rehabilitation program on the ward of origin after surgery has made possible the recovery of ambulation of most inpatients who referred independence at home in a few days, limiting hospitalization and health expenditure. CLINICAL REHABILITATION IMPACT: Data about recovery of ambulation with respect to the preoperative condition and destination after discharge resume the importance of identifying motor impairment after surgery, in order to apply an adequate, early and feasible rehabilitation protocol to inpatients, limiting hospitalization and health expenditure.
