Use of Incentive Spirometry in Adults following Cardiac, Thoracic, and Upper Abdominal Surgery to Prevent Post-Operative Pulmonary Complications: A Systematic Review and Meta-Analysis

Current practice of targeted breathing exercises after abdominal and cardiothoracic surgery: a national multicentre observational study

OBJECTIVES

To describe the timing and type of the first targeted breathing exercises after abdominal and cardiothoracic surgery, and to identify factors associated with early initiation (Commencement within three hours after arriival to a postoperative ward).

DESIGN

Multicentre observational study.

METHODS

In 18 hospitals in Sweden, the start time and type of targeted breathing exercises were recorded in consecutive series of patients who underwent abdominal or cardiothoracic surgery. Demographic data were retrieved from hospital records. Patients were divided into seven groups based on the category of surgery.

RESULTS

In total, 1492 patients were included in this study; of these, 1128 (76%) performed some form of targeted breathing exercise after surgery. Targeted breathing exercises commenced a median of 3.63 hours (interquartile range 1.58 to 11.75 hours) after arrival on a postoperative ward, with earlier commencement after minor abdominal surgery and later commencement after major abdominal surgery (P < 0.001). Most patients who performed targeted breathing exercises used positive expiratory pressure (n = 968/1492, 65%) or deep breathing without any devices (n = 207/1492, 14%). The odds of initiating breathing exercises within the first 3 hours after arrival on a postoperative ward were higher if a patient underwent pulmonary or abdominal surgery [odds ratio (OR) > 2.04; P < 0.001], or had intravenous analgesia (OR 1.50, 95% CI 1.05 to 2.14; P = 0.026). The odds were lower (OR 0.43, 95% CI 0.21 to 0.88; P = 0.021) for patients who arrived on the postoperative ward in the evening/night or for patients who had undergone laparoscopic surgery (OR 0.63, 0.43-0.92, p=0.018).

CONCLUSION

The majority (76%) of patients undergoing abdominal or cardiothoracic surgery performed some form of targeted breathing exercise, starting a median of 3.63 hours after arrival on a postoperative ward.

Perioperative lung expansion and pulmonary outcomes after open abdominal surgery versus usual care in the USA (PRIME-AIR): a multicentre, randomised, controlled, phase 3 trial

BACKGROUND

Postoperative pulmonary complications (PPCs) are a leading cause of morbidity, death, and increased use of health-care resources. We aimed to determine whether a perioperative lung expansion bundle including individualised intraoperative management reduces PPC severity in patients undergoing major open abdominal surgery compared with usual care.

METHODS

In this multicentre, randomised controlled phase 3 trial (PRIME-AIR), we enrolled adult patients (age ≥18 years) scheduled for an elective open abdominal surgery that would last at least 2 h, who were at intermediate or high risk for PPCs on the basis of their Assess Respiratory Risk in Surgical Patients in Catalonia (ARISCAT) score (a score of ≥26), and who had a BMI below 35 kg/m2 at 17 academic hospitals across ten states in the USA. Participants were randomly assigned (1:1), using permuted block randomisation (a mixture of blocks sizes of 2 and 4; in a 1:2 ratio), stratified by centre, to either usual care or a lung expansion bundle. The bundle comprised preoperative education on PPCs, intraoperative protective ventilation with individualised positive end-expiratory pressure (PEEP) to maximise respiratory system compliance, intraoperative neuromuscular blockade administration and reversal based on patient's weight and neuromuscular transmission monitoring, and postoperative supervised incentive spirometry and mobilisation encouragement. Anaesthesiologists at each site were also randomly assigned to either the intervention bundle group or usual care group, and at each site, at least one unmasked and one masked investigator was designated for each participant. Assessors were masked to treatment assignment. The primary outcome was the highest severity (grade 0-4) of a composite of PPCs by postoperative day 7, including hypoxaemia, respiratory symptoms, atelectasis, bronchospasm, respiratory infection, hypercapnia, pneumonia, pleural effusion, pneumothorax, and ventilatory dependence. The primary endpoint and safety were assessed in the modified intention-to-treat (mITT) population (ie, all participants randomly assigned to treatment who received surgery, and did not withdraw consent or verbal agreement, and excluded those found to be ineligible after randomisation, or for whom consent was not obtained for other reasons). This study is registered with ClinicalTrials.gov, NCT04108130, and is now complete.

FINDINGS

Between Jan 24, 2020, and April 5, 2023, we screened 1462 patients, of whom 794 were enrolled and randomly assigned to treatment. The mITT population included 751 participants, of whom 379 (50%) were in the intervention bundle group and 372 (50%) were in the usual care group. Mean age was 61·8 years (SD 12·8); 360 (48%) of 751 patients were female and 391 (52%) were male; 572 (76%) were White, 44 (6%) were Black, 35 (5%) were Asian, and ten (1%) were other races or more than one race. Adherence to bundle components was high (72-98%). Patients in the intervention bundle group received higher mean PEEP (7·5 cmH2O [SD 2·5] vs 5·6 cmH2O [1·4]) and more frequent per-protocol dosing of neuromuscular blockade (334 [88%] of 379 vs 214 [58%] of 372) and reversal (322 [86%] of 375 who received reversal medication vs 250 [70%] of 358) than did those in the usual care group. By postoperative day 7, the most common PPC severity was grade 2 (211 [56%] of 379 in intervention bundle group vs 225 [60%] of 372 in the usual care group). Mean PPC severity was similar in both groups (1·60 [SD 0·94] vs 1·53 [0·93]; mean difference 0·07 [95% CI -0·03 to 0·18]; p=0·19). Occurrence of serious adverse events was similar in both groups. At 7 days postoperatively, one (<1%) patient in the intervention bundle group and two (1%) in the usual care group had died; at 30 days, cumulatively, one (<1%) patient and four (1%) patients had died; and at 90 days, cumulatively, six (2%) patients and five (1%) patients had died, respectively. Adverse events occurred in 71 (19%) of 379 patients in the intervention bundle group and 54 (14%) of 372 in the usual care group, and 35 (9%) patients in each group had serious adverse events.

INTERPRETATION

In patients with a BMI of less than 35 kg/m2 who are at moderate-to-high risk of PPCs and undergoing prolonged major open abdominal surgery, a perioperative lung expansion bundle did not reduce PPC severity compared with usual care provided at US academic hospitals.

Diaphragmatic ultrasound: approach, emerging evidence, and future perspectives in non-ICU patients

Diaphragmatic dysfunction is an important contributor to hypercapnic respiratory failure, but its presence is often challenging to determine at the bedside. Diaphragm ultrasound provides an opportunity to evaluate the function of the diaphragm noninvasively by evaluating the following parameters that can help define diaphragmatic dysfunction: diaphragm excursion, diaphragm muscle thickness, and thickening fraction. Its evaluation has the potential to assist with diagnosis of respiratory failure, provide prognosis, and assist with patient monitoring and should be considered as part of an internal medicine physician's and emergency physician's skill set. This article provides an overview on how to perform diaphragm ultrasound, review its pitfalls, and discuss the evidence of its use in patients with neuromuscular disorders and chronic obstructive pulmonary disease. Finally, its potential emerging uses in the perioperative setting and for evaluation of acute heart failure are discussed.

From surgery to recovery: Measuring success through quality of life and functional improvements after cardiac surgery

Coronary artery disease and aortic valve stenosis are highly prevalent cardiovascular diseases worldwide, resulting in substantial morbidity and mortality. Surgical interventions, such as coronary artery bypass grafting and surgical aortic valve replacement, offer significant therapeutic benefits, including enhanced postoperative quality of life (QoL) and functional capacity, which are key indicators of surgical success. This editorial reviews recent studies on postoperative QoL and functional outcomes in patients undergoing cardiac surgery. Factors such as preoperative health, age, intensive care unit stay duration, surgical risk, and perioperative complications could influence these outcomes. Cardiac rehabilitation is pivotal in enhancing patient function, reducing frailty and improving long-term QoL.

The effect of preoperative deep breathing exercise with incentive spirometer initiated in the preoperative period on respiratory parameters and complications in patients underwent open heart surgery: a randomized controlled trial

BACKGROUND

Incentive spirometer is used in lung expansion therapy to maintain alveolar patency and improve pulmonary volumes in postoperative cardiac surgical patients. Deep breathing exercises with an incentive spirometer significantly reduce the development of postoperative pulmonary complications after open-heart cardiac surgery.

AIM

To determine the effect of deep breathing exercises with an incentive spirometer initiated in the preoperative period on respiratory parameters and complications in patients who underwent open-heart surgery.

METHODS

This randomized controlled study was conducted with a total of 66 participants. The participants were randomized into a deep breathing group (n = 32) and a control group (n = 34). The control group received hospital routine physiotherapy, and the deep breathing group started to perform deep breathing exercises with an incentive spirometer in the preoperative period. Data were collected with the Sociodemographic and Medical Data Form and Patient Follow-up Form (respiratory rate, oxygen saturation (SpO2) level, arterial blood gas parameters and posteroanterior chest X-ray were monitored with this form prepared by the investigators). The Medical Research Council Scale was used to determine the severity of dyspnea in the patients included in the study. Primary outcomes included respiratory rate, oxygen saturation, arterial blood gas parameters, posteroanterior chest X-ray, and evaluation of postoperative pulmonary complications development. Secondary outcomes included the mechanical ventilation time, length of intensive care unit stay, and length of hospital stay.

RESULTS

The incidence of postoperative pulmonary complications was 3.1% and 23.5% (p < 0.05) in the deep breathing and control groups, respectively. The mechanical ventilation time, length of hospital stay, and length of stay in the intensive care unit were significantly shorter in the deep breathing group (p < 0.05). In the deep breathing group, the mean SpO2 values evaluated before surgery, on the first day in the Cardiovascular Surgery Unit, and on the day of discharge were significantly higher than the control group (p < 0.05).

CONCLUSION

Deep breathing exercises with an incentive spirometer initiated in the preoperative period contribute to a reduction in postoperative pulmonary complication rates, shortening of mechanical ventilation time, length of stay in the intensive care unit, length of hospital stay, and improvement of pre- and postoperative oxygenation.

The Role of Incentive Spirometry in Enhanced Recovery After Lung Cancer Resection: A Propensity Score-Matched Study

Background: Postoperative physiotherapy is a cornerstone of Enhanced Recovery After Surgery (ERAS) programs, especially following lung resection. Despite its importance, the literature lacks clear recommendations and guidelines, particularly regarding the role of incentive spirometry (IS). This study aims to determine whether incentive spirometry offers additional benefits over early ambulation alone in patients undergoing lung resection for primary lung cancer. Methods: We conducted a retrospective case-control study at the European Institute of Oncology (IEO) involving patients who underwent lung resection from June 2020 to June 2022. Patients were divided into two cohorts: early ambulation alone (control group) and early ambulation with IS (IS group). The primary endpoint was the rate of postoperative pulmonary complications. Secondary endpoints included length of hospital stay and time to chest drain removal. A propensity score-matched analysis was performed based on age, sex, and BMI. Data were compared using Chi-squared and Student's t-tests as appropriate. Results: A total of 304 patients were included, with 153 in the intervention group and 151 in the control group. After propensity-score matching, 52 patients from each cohort were compared. No significant differences were found between the groups regarding postoperative oxygen requirement, fever, atelectasis, residual pleural space, need for bronchoscopy toilette, and re-hospitalization rate. IS group showed trends toward shorter hospital stays and lower time to chest drain removal, though without reaching statistical significance. Conclusions: IS did not significantly improve postoperative outcomes compared to early ambulation alone in patients undergoing lung resection for primary lung cancer. More extensive, prospective, randomized trials are needed to confirm these findings.

Inspiratory Muscle Training Before Esophagectomy Increases Diaphragmatic Excursion: A Randomized Controlled Trial

BACKGROUND

Inspiratory muscle training (IMT) has preventive effects against postoperative pulmonary complications (PPCs) after upper abdominal surgery. However, its impact on diaphragmatic function has not been evaluated. This study investigated the effect of preoperative IMT on diaphragmatic excursion (DE) and prevention of PPCs for patients with esophageal cancer.

METHODS

This study was an unblinded, parallel, randomized controlled trial. Patients with thoracic or abdominal esophageal cancer scheduled for esophagectomy were randomized into the incentive spirometry (IS) or IMT group. During preoperative neoadjuvant chemotherapy, IS or IMT intervention was performed. The inspiratory resistance of the IMT group was consistently set at 50% maximal inspiratory pressure. The primary outcome was the amount of change in DE evaluated with ultrasonography, and the secondary outcome was the incidence of Clavien-Dindo grade II or higher PPCs.

RESULTS

This study recruited 42 patients. Among these patients 21 were randomized into the IS or IMT group, and 2 patients dropped out from the study. Finally, 40 patients were included in this analysis. The DE of the IMT group increased significantly after the intervention. The IMT group had significantly larger DE changes than the IS group. Of the 39 patients analyzed for postoperative outcome, 5 experienced grade II PPCs. The IMT group had a lower incidence of PPCs than the IS group.

CONCLUSIONS

Patients with thoracic and abdominal esophageal cancer scheduled for surgery who had preoperative IMT have increased DE, which may have an important role in prevention of PPCs.

Clinical Practice Guideline: Recommendations for the Perioperative Management of Pancreatic and Colorectal Cancer Patients

BACKGROUND

Colorectal and pancreatic carcinoma are the most common cancers of the gastrointestinal tract. Their surgical treatment carries a high morbidity: complications arise in 25% to 30% of cases, often prolonging recovery times and delaying the initiation of adjuvant therapy, leading, in turn, to worse oncological outcomes. The goal of multimodal perioperative management (mPOM) is to lower the postoperative complication rate through a combination of perioperative measures.

METHODS

This guideline on the perioperative management of gastrointestinal tumors (POMGAT) meets all requirements for an S3 guideline as specified by the Association of the Scientific Medical Societies in Germany (Arbeitsgemeinschaft der Wissenschaftlichen Medizinischen Fachgesellschaften, AWMF). These include a systematic literature search, quality assessment of the included publications, an evaluation of the reliability of the evidence according to the GRADE approach, and a structured consensus process.

RESULTS

Meta-analyses have shown that mPOM lowers the complication rates of both pancreatic and colorectal resections (RD 0.96 with 95% confidence interval [0.92; 0.99] and RR 0.66 [0.54; 0.80], respectively). This shortens the hospital stay after pancreatic resections by a median of 2.33 days [-2.98; -1.69] and after colorectal resections by a median of 2.59 days [-3.22; -1.97].

CONCLUSION

Adherence to the POMGAT-S3 guideline for pancreatic and colorectal cancer surgery is associated with improved recovery, which can lead to a faster return to intended oncological treatment (RIOT) and thus to better long-term outcomes. These recommendations are not restricted to gastrointestinal cancer surgery; they can also be applied to visceral surgery for benign conditions, as well as to gynecological and urological operations.

Is Incentive Spirometry Superior to Standard Care in Postoperative Cardiac Surgery on Clinical Outcomes and Length of Hospital and Intensive Care Unit Stay? A Systematic Review with Meta-Analysis

INTRODUCTION

Cardiac surgery is a frequent surgical procedure and may present a high risk of complications. Among the prophylactic strategies studied to decrease the rates of negative outcomes, respiratory care seems to reduce pulmonary complications. Incentive spirometry (IS) is a low-cost, respiratory exercise technique, used for the prevention and treatment of postoperative pulmonary complications (PPC). The aim of this review was to evaluate whether IS is superior to respiratory care, mobilization exercises, and noninvasive ventilation on PPC, and clinical outcomes.

METHODS

Systematic review. Medical Literature Analysis and Retrieval System Online (or MEDLINE®), Embase®, Cochrane Central Register of Controlled Trials (or CENTRAL), Physiotherapy Evidence Database (or PEDro), Cumulative Index of Nursing and Allied Health (or CINAHL®), Latin American and Caribbean Health Sciences Literature (or LILACS), Scientific Electronic Library Online (or SciELO), Allied, Scopus®, and OpenGrey databases, clinical trial registration sites, conferences, congresses, and symposiums were searched.

RESULTS

Twenty-one randomized trials and one quasi-randomized trial (1,677 participants) were included. For partial pressure of oxygen (PaO2), IS was inferior to respiratory care (mean difference [MD] -4.48; 95% confidence interval [CI] -8.32 to -0.63). Flow-oriented IS was inferior to respiratory care on PaO2 (MD -4.53; 95% CI -8.88 to -0.18). However, compared to respiratory care, flow-oriented IS was superior on recovery vital capacity.

CONCLUSIONS

This meta-analysis revealed that IS was not superior to standard respiratory care for PPCs and clinical outcomes, therefore its use should not be widely recommended until further studies with high quality be performed to ensure this clinical guidance.

The effect of incentive spirometry in perioperative patients with lung cancer-a systematic review and meta-analysis

BACKGROUND

Incentive spirometry (IS) as a routine respiratory therapy during the perioperative period has been widely used in clinical practice. However, the impact of IS on patients with perioperative lung cancer remains controversial. This review aimed to evaluate the efficacy of IS in perioperative pulmonary rehabilitation for patients with lung cancer.

METHODS

Cochrane Library, PubMed, Web of Science, Ovid, CINAHL, Chinese National Knowledge Infrastructure, Weipu, and Wanfang Databases were searched from inception to 30 November 2023. Only randomized controlled trials were included in this systematic review. The PRISMA checklist served as the guidance for conducting this review. The quality assessment of the included studies was assessed by the Cochrane risk-of-bias tool. The meta-analysis was carried out utilizing Review Manager 5.4. Furthermore, sensitivity analysis and subgroup analysis were also performed.

RESULTS

Nine studies recruited 1209 patients met our inclusion criteria. IS combined with other respiratory therapy techniques was observed to reduce the incidence of postoperative pulmonary complications, enhance pulmonary function, curtail the length of hospital stay, and lower the Borg score. Nevertheless, no improvements were found in the six-minute walk distance or quality of life score.

CONCLUSIONS

Although IS demonstrates benefits as a component of comprehensive intervention measures for perioperative patients with lung cancer, it proves challenging to determine the precise impact of IS as a standalone component within the comprehensive intervention measures. Therefore, further researches are required to better understand the effectiveness of IS isolation and its interactions when integrated with additional respiratory therapies for these patients.

Effectiveness of a Modified Nurse-Led COUGH Bundle for Obese Patients After Bariatric Surgery

BACKGROUND

Obesity commonly affects postsurgical pulmonary outcomes and is associated with increased oxygen usage, length of recovery and hospital stay, discharge to high levels of care, cost, morbidity, and mortality.

LOCAL PROBLEM

No standardized pulmonary care bundle for obese patients after bariatric surgery was available in the postanesthesia care unit (PACU) at a hospital in Singapore.

METHODS

This quality improvement project was a prospective, single-cohort, pre- and posttest intervention design with 151 patients recruited.

INTERVENTIONS

Teaching and implementation of a modified nurse-led COUGH bundle was carried out on obese patients after their bariatric surgery.

RESULTS

Postbariatric surgery patients with the nurse-led COUGH bundle had significantly less consumption of oxygen in the PACU and step-down units. The PACU and hospital length of stay were also reduced.

CONCLUSIONS

The modified nurse-led COUGH bundle can reduce patients' oxygen usage and hospital stay after their bariatric surgery.

Analysis of the impact of ERAS-based respiratory function training on older patients’ ability to prevent pulmonary complications after abdominal surgery

BACKGROUND

In China, as the population grows older, the number of elderly people who have died from respiratory problems has increased.

AIM

To investigate whether enhanced recovery after surgery (ERAS)-based respiratory function training may help older patients who had abdominal surgery suffer fewer pulmonary problems, shorter hospital stays, and improved lung function.

METHODS

The data of 231 elderly individuals having abdominal surgery was retrospectively analyzed. Based on whether ERAS-based respiratory function training was provided, patients were divided into ERAS group (n = 112) and control group (n = 119). Deep vein thrombosis (DVT), pulmonary embolism (PE), and respiratory tract infection (RTI) were the primary outcome variables. Secondary outcome variables included the Borg score Scale, FEV1/FVC and postoperative hospital stay.

RESULTS

The percentage of 18.75% of ERAS group participants and 34.45% of control group participants, respectively, had respiratory infections (P = 0.007). None of the individuals experienced PE or DVT. The ERAS group’s median postoperative hospital stay was 9.5 d (3-21 d) whereas the control groups was 11 d (4-18 d) (P = 0.028). The Borg score decreased on the 4^th d following surgery in the ERAS group compared to the 2^nd d prior (P = 0.003). The incidence of RTIs was greater in the control group than in the ERAS group among patients who spent more than 2 d in the hospital before surgery (P = 0.029).

CONCLUSION

ERAS-based respiratory function training may reduce the risk of pulmonary complications in older individuals undergoing abdominal surgery.

Perioperative Optimization of the Cardiac Surgical Patient

Perioperative optimization of cardiac surgical patients is imperative to reduce complications, utilize health care resources efficiently, and improve patient recovery and quality of life. Standardized application of evidence-based best practices can lead to better outcomes. Although many practices should be applied universally to all patients, there are also opportunities along the surgical journey to identify patients who will benefit from additional interventions that will further ameliorate their recovery. Enhanced recovery programs aim to bundle several process elements in a standardized fashion to optimize outcomes after cardiac surgery. A foundational concept of enhanced recovery is attaining a better postsurgical end point for patients, in less time, through achievement and maintenance in their greatest possible physiologic, functional, and psychological state. Perioperative optimization is a broad topic, spanning multiple phases of care and involving a variety of medical specialties and nonphysician health care providers. In this review we highlight a variety of perioperative care topics, in which a comprehensive approach to patient care can lead to improved results for patients, providers, and the health care system. A particular focus on patient-centred care is included. Although existing evidence supports all of the elements reviewed, most require further improvements in implementation, as well as additional research, before their full potential and usefulness can be determined.

[The use of oscillatory respiratory therapy with positive expiratory pressure (PEP-therapy) to restore the functional state of the lungs in patients after cardiac surgery]

Postoperative pulmonary complications in cardiac surgery patients occur in 10-35% of cases, depending on differences in their definition, patient characteristics and type of surgical intervention, most of them are associated with ineffective coughing and evacuation of bronchial secretions.

OBJECTIVE

To determine the effectiveness of stimulating the evacuation of bronchial secretions with the help of oscillating PEP therapy carried out during the first three days.

MATERIAL AND METHODS

A randomized prospective study of 60 adult patients after elective cardiac surgery was performed (Clinical Trials.gov. protocol number NCT05159401). Oscillatory PEP-therapy was performed in 30 patients using Acapella DHGreen device (SmithMedicalASD, USA) 10-12 hours after tracheal extubation 3 times a day for 3 days after surgery. The control group (30 patients). The inclusion criteria: age over 18 years, spontaneous breathing after tracheal extubation, clear consciousness and productive contact with the patient, the ability to maintain adequate gas exchange on the low-flow oxygen inhalation, adequate analgesia (<2 points of VAS). Exclusion criteria: the need for re-intubation and mechanical ventilation, non-invasive mask ventilation, high-flow oxygen therapy, acute cerebrovascular accident, ongoing bleeding, cardiac insufficiency (inotropic index >10), shocks syndrome of various etiologies, the use of any extracorporeal support, any neuromuscular disorders, pneumothorax, hydro-or hemothorax. Before each session and 20 minutes after its end, when breathing air, blood oxygen saturation was recorded using a pulse oximeter (SpO2), the maximum inspiratory capacity (MIC) was measured using a Coach-2 incentive spirometer from SmithsMedical and spirometry with a portable ultrasonic spirometer Spiro Scout (Schiller, Switzerland). For the purposes of this work, the total index of the spirometry maximum inspiratory capacity (SMIC) was used - the sum of the respiratory volume and the reserve volume of inspiration in ml.

RESULTS

Difficulties in evacuation of sputum were noted in 90% of patients. Three-day sessions of oscillating PEP- therapy are accompanied by a significant improvement in the passage of sputum, as evidenced by a 3-fold increase in the number of patients with productive cough. The increase in MIC in the main group was 46.9% and 21.3%, respectively (p=0.042), and the number of patients with values greater than MICo. 1500 ml increased from 23.3% to 7.6% (p<0.001). The effectiveness of oscillatory PEP-therapy is confirmed by a 7-fold decrease in the frequency of radiological changes in the lungs at the end of sessions (p<0.001), while in the control group the frequency of their occurrence practically did not change and remained at a high level. The total number of patients with respiratory insufficiency (SpO2≤92%) decreased by 8.6 times after completion of all PEP- therapy sessions (p=0.001), however, without statistically significant difference with the control group.

CONCLUSIONS

Oscillatory PEP- therapy in cardiac surgery patients has a positive effect on sputum passage, ventilation parameters and oxygenating lung function. The procedure was well tolerated and there were no complications associated with it.

Perioperative care for major elective surgery: a survey of Brazilian physiotherapists

Abstract Introduction: Major surgeries are highly complex procedures and have a higher incidence of respiratory morbidity and mortality compared to other types of surgery. Postoperative pulmonary complications (PPC) are common after such surgeries and are associated with increased hospital stay, health care costs and surgical patient mortality. Objective: To investigate the most commonly used physical therapy techniques for the prevention and treatment of PPC among thoracic and abdominal surgery patients in all regions of Brazil. Methods: A total of 489 randomly selected physiotherapists who provided perioperative care for patients undergoing elective abdominal, thoracic or cardiac surgeries participated in this study. A questionnaire with nine questions about routine care and therapeutic choices for the surgical population was developed and assessed by 10 specialists before being administered to the physiotherapists. Results: Among the physiotherapists (63% with at least 5 years of experience with surgical patients), 50.9% considered the patient’s surgical risk in their treatment either always or often. A total of 53.8% patients were treated by the physiotherapist following a physician’s prescription. The most mentioned physical therapy techniques used to prevent PPC were postoperative mobilization/exercises (59.3%), postoperative lung expansion (52.8%), and preoperative advice (50.7%). In addition, 80.6% of the physiotherapists believe that incentive spirometry prevents PPC, while 72.8% expected this effect from positive airway pressure devices. Conclusion: Most physiotherapists in Brazil who work with surgical patients offer preoperative professional advice, use postoperative early mobilization and lung expansion techniques to prevent PPC, and consider the patient's surgical risk during treatment. In addition, some physical therapy sessions are routinely performed preoperatively.
