Mobilization Started Within 2 Hours After Abdominal Surgery Improves Peripheral and Arterial Oxygenation: A Single-Center Randomized Controlled Trial.

OBJECTIVE: The aim of this study was to investigate if mobilization out of bed, within 2 hours after abdominal surgery, improved participants' respiratory function and whether breathing exercises had an additional positive effect. METHODS: Participants were 214 consecutively recruited patients who underwent elective open or robot-assisted laparoscopic gynecological, urological, or endocrinological abdominal surgery with an anesthetic duration of >2 hours. They were recruited to a randomized controlled trial. Immediately after surgery, patients were randomly assigned to 1 of 3 groups: mobilization (to sit in a chair) and standardized breathing exercises (n = 73), mobilization (to sit in a chair) only (n = 76), or control (n = 65). The interventions started within 2 hours after arrival at the postoperative recovery unit and continued for a maximum of 6 hours. The primary outcomes were differences in peripheral oxygen saturation (SpO2, as a percentage) and arterial oxygen pressure (PaO2, measured in kilopascals) between the groups. Secondary outcomes were arterial carbon dioxide pressure, spirometry, respiratory insufficiency, pneumonia, and length of stay. RESULTS: Based on intention-to-treat analysis (n = 214), patients who received mobilization and breathing exercises had significantly improved SpO2 (mean difference [MD] = 2.5%; 95% CI = 0.4 to 4.6) and PaO2 (MD = 1.40 kPa; 95% CI = 0.64 to 2.17) compared with the controls. For mobilization only, there was an increase in PaO2 (MD = 0.97 kPa; 95% CI = 0.20 to 1.74) compared with the controls. In the per-protocol analysis (n = 201), there were significant improvements in SpO2 and PaO2 for both groups receiving mobilization compared with the controls. Secondary outcome measures did not differ between groups. CONCLUSION: Mobilization out of bed, with or without breathing exercises, within 2 hours after elective abdominal surgery improved SpO2 and PaO2. IMPACT: The respiratory effect of mobilization (out of bed) immediately after surgery has not been thoroughly evaluated in the literature. This study shows that mobilization out of bed following elective abdominal surgery can improve SpO2 and PaO2. LAY SUMMARY: Mobilization within 2 hours after elective abdominal surgery, with or without breathing exercises, can improve patients' respiratory function.

Effect of early activity combined with early nutrition on acquired weakness in ICU patients.

INTRODUCTION: Intensive care unit-acquired weakness (ICU-AW) occurs in 25% to 100% of critically ill patients, and is associated with prolonged mechanical ventilation, extended ICU stay, and total hospital stay, increased hospital costs, higher risk of death, impaired physical function, and decreased quality of life. However, there are not any current guidelines that mention management of ICU-AW. The present study will evaluate the effects of a combination of early nutrition and early exercise compared to those of either early exercise alone or the standard care for patients in ICUs. METHODS: This is a 3-arm, parallel, randomized controlled trial including an estimated 147 critically ill patients aged ≥18 years recruited from the ICUs of 2 hospitals in Heilongjiang, China. Patients will be prospectively randomized 1:1:1 to receive early mobilization, early nutrition combined with early mobilization, or standard care (minimal exercises, experience-based initiation and enrollment of nutrition support). Outcomes are assessed at ICU discharge after baseline. The primary outcome is occurrence of ICU-AW according to the Medical Research Council scale at the end of treatment. Muscle strength, organ failure, functional independence, self-care ability, time of ICU stay, duration of mechanical ventilation, and ICU mortality are secondary outcome measures. DISCUSSION: This trial has the potential to identify a novel strategy for preventing or managing ICU-AW. The findings may increase the clinical knowledge about nutrition and mobilization interventions for people with ICU-AW, and contribute to the formation of practice guidelines for managing this condition.

Muscle Mass Loss in the Older Critically Ill Population: Potential Therapeutic Strategies.

Skeletal muscle plays a critical role in everyday life, and its age-associated reduction has severe health consequences. The pre-existing presence of sarcopenia, combined with anabolic resistance, protein undernutrition, and the pro-catabolic/anti-anabolic milieu induced by aging and exacerbated in critical care, may accelerate the rate at which skeletal muscle is lost in patients with critical illness. Advancements in intensive care unit (ICU)-care provision have drastically improved survival rates; therefore, attention can be redirected toward other significant issues affecting ICU patients (e.g., length of stay, days on ventilation, nosocomial disease development, etc.). Thus, strategies targeting muscle mass and function losses within an ICU setting are essential to improve patient-related outcomes. Notably, loading exercise and protein provision are the most compelling. Many older ICU patients seldom meet the recommended protein intake, and loading exercise is difficult to conduct in the ICU. Nevertheless, the incorporation of physical therapy (PT), neuromuscular electrical stimulation, and early mobilization strategies may be beneficial. Furthermore, a number of nutrition practices within the ICU have been shown to improve patient-related outcomes ((e.g., feeding strategy [i.e., oral, early enteral, or parenteral]), be hypocaloric (∼70%-80% energy requirements), and increase protein provision (∼1.2-2.5 g/kg/d)). The aim of this brief review is to discuss the dysregulation of muscle mass maintenance in an older ICU population and highlight the potential benefits of strategic nutrition practice, specifically protein, and PT within the ICU. Finally, we provide some general guidelines that may serve to counteract muscle mass loss in patients with critical illness.

Early rehabilitation reduces the likelihood of developing intensive care unit-acquired weakness: a systematic review and meta-analysis.

BACKGROUND: Intensive care unit-acquired weakness (ICUAW) is associated with significant impairments in body structure and function, activity limitation, and participation restriction. The etiology and management of ICUAW remain uncertain. OBJECTIVE: To estimate the extent to which early rehabilitation interventions (early mobilization [EM] and/or neuromuscular electrical stimulation [NMES]) compared to usual care reduce the incidence of ICUAW in critically ill patients. DATA SOURCES: We searched MEDLINE, EMBASE, CINAHL, Cochrane Central and Physiotherapy Evidence Database databases from inception to May 1st, 2017. ELIGIBILITY CRITERIA: Randomized controlled trials of EM and/or NMES interventions in critically ill adults. DATA EXTRACTION AND DATA SYNTHESIS: Data on the incidence of ICUAW and secondary outcomes were extracted. Both odds and risk ratios for ICUAW were pooled using the random-effects model. RESULTS: We identified 1421 reports after duplicate removal. Nine studies including 841 patients (419 intervention and 422 usual care) were included in the final analysis. The interventions involved EM in five trials, NMES in three trials, and both EM and NMES in one trial. Early rehabilitation decreased the likelihood of developing ICUAW: odds ratio of 0.63 (95% CI: 0.43 to 0.92) in the screened population, and 0.71 (95% CI: 0.53 to 0.95) in the randomized population. CONCLUSION, IMPLICATIONS OF KEY FINDINGS: Early rehabilitation was associated with a decreased likelihood of developing ICUAW. Our findings support early rehabilitation in the ICU. While results were consistent in both the screened and randomized populations, the wide confidence intervals suggest that well-conducted trials are needed to validate our findings.

The effect of rehabilitation interventions on physical function and immobility-related complications in severe stroke: a systematic review.

OBJECTIVE: To evaluate the effectiveness of rehabilitation interventions on physical function and immobility-related complications in severe stroke. DESIGN: Systematic review of electronic databases (Medline, Excerpta Medica database, Cumulative Index to Nursing and Allied Health Literature, Allied and Complementary Medicine Database, Physiotherapy Evidence Database, Database of Research in Stroke, Cochrane Central Register of Controlled Trials) searched between January 1987 and November 2018. METHODS: The Preferred Reporting Items for Systematic Reviews and Meta-Analysis statement guided the review. Randomised controlled trials comparing the effect of one type of rehabilitation intervention to another intervention, usual care or no intervention on physical function and immobility-related complications for patients with severe stroke were included. Studies that recruited participants with all levels of stroke severity were included only if subgroup analysis based on stroke severity was performed. Two reviewers screened search results, selected studies using predefined selection criteria, extracted data and assessed risk of bias for selected studies using piloted proformas. Marked heterogeneity prevented meta-analysis and a descriptive review was performed. The Grading of Recommendations Assessment, Development and Evaluation approach was used to assess evidence strength. RESULTS: 28 studies (n=2677, mean age 72.7 years, 49.3% males) were included in the review. 24 studies were rated low or very low quality due to high risk of bias and small sample sizes. There was high-quality evidence that very early mobilisation (ie, mobilisation with 24 hours poststroke) and occupational therapy in care homes were no more effective than usual care. There was moderate quality evidence supporting short-term benefits of wrist and finger neuromuscular electrical stimulation in improving wrist extensor and grip strength, additional upper limb training on improving upper limb function and additional lower limb training on improving upper limb function, independence in activities of daily living, gait speed and gait independence. CONCLUSIONS: There is a paucity of high-quality evidence to support the use of rehabilitation interventions to improve physical function and reduce immobility-related complications after severe stroke. Future research investigating more commonly used rehabilitation interventions, particularly to reduce poststroke complications, is required. PROSPERO REGISTRATION NUMBER: CRD42017077737.

Mobilising the patient: With emphasis on innovative technologies.

Treatment of trauma patients and fractures has changed dramatically throughout the years. From conservative methods to nowadays various kinds of screws, pins, plates and nails for optimal fixation of fractures. This lead to changes in post-operative management as well, from bedrest to (partial) weight bearing. Some patients however have very limited to no ability to mobilise, such as critical ill patients on the Intensive Care Unit, amputees or spinal cord injured patients. Due to innovations such as hydrotherapy, osseointegrated prosthesis and exoskeletons, even these people can mobilise. Thanks to innovations like these an increasing number of trauma patients are able to fully reintegrate into community life and get back to an active and independent life style.

Joint mobilization and static stretching for individuals with chronic ankle instability - A pilot study.

OBJECTIVE: To complete preliminary analysis regarding the effects joint mobilization timing during a 4-week calf stretching intervention on clinician-oriented and patient-oriented outcomes in individuals with chronic ankle instability (CAI). Additionally, a secondary objective was to examine the combined effect of joint mobilization and calf stretching. DESIGN: Randomized two-group pretest posttest design. SETTING: Laboratory. PARTICIPANTS: Ten adults (age = 24.4 ±â€¯4.7years; height = 172.1 ±â€¯11.3 cm; weight = 76.2 ±â€¯17.1 kg) with self-reported CAI participated. INTERVENTIONS: Participants completed outcome measures at three collection sessions (baseline, pre-intervention, and post-intervention). Participants were randomized into either into an early-mobilization or late-mobilization group in which they completed a joint mobilization intervention during the first or last 2 weeks of a 4-week calf stretching intervention. MAIN OUTCOME MEASURES: Outcome measures included: dorsiflexion ROM, dynamic postural control, single-limb postural control, Disablement in the Physically Active Scale (DPA), Foot and Ankle Ability Measure (FAAM), and Fear-Avoidance Beliefs Questionnaire (FABQ). Wilcoxon Sign Rank Tests examined pre-intervention to post-intervention differences for each dependent variable. Mann-Whitney U tests examined differences between early-mobilization and late-mobilization groups. Alpha was set a priori at p < .05. RESULTS: No significant differences were identified between early-mobilization and late-mobilization groups at post intervention (p > .095). FAAM-Activities of Daily Living, DPA, FABQ-Physical Activity, and dorsiflexion ROM were significantly improved at post-intervention compared to pre-intervention (p < .047). No other significant differences were identified between pre-intervention and post-intervention (p > .057). CONCLUSION: Preliminarily results suggest the timing of joint mobilization when used in conjunction with calf stretching does not effect treatment efficacy. However, the combination of joint mobilization and calf stretching can improve dorsiflexion ROM and self-reported function in individuals with CAI. Improvements from the combined intervention are similar to previously reported effects of isolated joint mobilization or stretching.

Ambulation capacity and functional outcome in patients undergoing neuromuscular electrical stimulation after cardiac valve surgery: A randomised clinical trial.

BACKGROUND: Early mobilization and physical exercise are considered fundamental components in cardiovascular surgery rehabilitation; however, occasionally they are inadequate for inhibiting functional decline. Neuromuscular electrical stimulation (NMES) is a promising tool in cardiovascular rehabilitation; however, to date, no randomized clinical trial has measured the effects of NMES on functional capacity and quality of life in patients who undergo routine cardiac surgery with a short intensive care unit (ICU) stay. Therefore, we aimed to investigate the effects of NMES on walking ability, muscle strength, functional independence, and quality of life in cardiac valve surgery patients in the immediate postoperative period. METHODS: A randomized, parallel, controlled, 2-arm clinical trial with assessor blinding was conducted. Fifty-nine adult patients in the preoperative period after cardiac valve reconstruction and/or replacement were randomly assigned to a control or intervention group. The intervention group underwent NMES in the quadriceps and gastrocnemius, bilaterally, for 60 minutes, for up to 10 sessions. The primary outcome was ambulation ability, assessed through the Six-Minute Walk Test and Walking Speed Test at postoperative day 5 (5PO). Secondary outcomes were muscular strength (assessed through the Medical Research Council scale), functional independence measure (assessed through the Functional Independence Measurement Questionnaire), and quality of life (assessed through the Nottingham Health Profile) at baseline (preoperative) and at postoperative days 3 and 5. RESULTS: The baseline characteristics were similar in both groups, except for body mass index. There was no statistically significant difference, with a small effect size, between both groups regarding the distance walked (95% CI, -64.87 to 65.97) and walking speed (95% CI, -0.55 to 0.57). There was a statistically significant difference in upper-limb muscle strength loss and decline in mobility at postoperative day 3, which had a tendency to recover to initial values at 5PO, in both groups. No significant between-group difference was noted for muscle strength, functional independence, and quality of life. CONCLUSIONS: The use of NMES had no effect on walking ability, strength, quality of life, or functional outcome in the postoperative period for patients that underwent regular valve replacement.

Physiotherapy education and training prior to upper abdominal surgery is memorable and has high treatment fidelity: a nested mixed-methods randomised-controlled study.

OBJECTIVES: To (1) assess memorability and treatment fidelity of pre-operative physiotherapy education prior to elective upper abdominal surgery and, (2) to explore patient opinions on pre-operative education. DESIGN: Mixed-methods analysis of a convenience sample within a larger parallel-group, double-blinded, randomised controlled trial with concealed allocation and intention-to-treat analysis. SETTING: Tertiary Australian hospital. PARTICIPANTS: Twenty-nine patients having upper abdominal surgery attending pre-admission clinic within six-weeks of surgery. INTERVENTION: The control group received an information booklet about preventing pulmonary complications with early ambulation and breathing exercises. The experimental group received an additional face-to-face 30-minute physiotherapy education and training session on pulmonary complications, early ambulation, and breathing exercises. OUTCOME MEASURES: Primary outcome was proportion of participants who remembered the taught breathing exercises following surgery. Secondary outcomes were recall of information sub-items and attainment of early ambulation goals. These were measured using standardised scoring of a semi-scripted digitally-recorded interview on the 5th postoperative day, and the attainment of early ambulation goals over the first two postoperative days. RESULTS: Experimental group participants were six-times more likely to remember the breathing exercises (95%CI 1.7 to 22) and 11-times more likely (95%CI 1.6 to 70) to report physiotherapy as the most memorable part of pre-admission clinic. Participants reported physiotherapy education content to be detailed, interesting, and of high value. Some participants reported not reading the booklet and professed a preference for face-to-face information delivery. CONCLUSION: Face-to-face pre-operative physiotherapy education and training prior to upper abdominal surgery is memorable and has high treatment fidelity. TRIAL REGISTRATION: ACTRN-12613000664741.

Does the addition of deep breathing exercises to physiotherapy-directed early mobilisation alter patient outcomes following high-risk open upper abdominal surgery? Cluster randomised controlled trial.

OBJECTIVE: To investigate whether the inclusion of deep breathing exercises in physiotherapy-directed early mobilisation confers any additional benefit in reducing postoperative pulmonary complications (PPCs) when patients are treated once daily after elective open upper abdominal surgery. This study also compared postoperative outcomes following early and delayed mobilisation. DESIGN: Cluster randomised controlled trial. SETTING: Single-centre study in a teaching hospital. PARTICIPANTS: Eighty-six high-risk patients undergoing elective open upper abdominal surgery. INTERVENTION: Three groups: early mobilisation (Group A), early mobilisation plus breathing exercises (Group B), and delayed mobilisation (mobilised from third postoperative day) plus breathing exercises (Group C). MAIN OUTCOMES: PPCs and postoperative outcomes [number of days until discharge from physiotherapy, physiotherapy input and length of stay (LOS)]. RESULTS: There was no significant difference in PPCs between Groups A and B. The LOS for Group A {mean 10.7 [standard deviation (SD) 5.0] days} was significantly shorter than the LOS for Groups B [mean 16.7 (SD 9.7) days] and C [mean 15.2 (SD 9.8) days; P=0.036]. The greatest difference was between Groups A and B (mean difference -5.93, 95% confidence interval -10.22 to -1.65; P=0.008). Group C had fewer smokers (26%) and patients with chronic obstructive pulmonary disease (0%) compared with Group B (53% and 14%, respectively). This may have led to fewer PPCs in Group C, but the difference was not significant. Despite Group C having fewer PPCs and less physiotherapy input, the number of days until discharge from physiotherapy and LOS were similar to Group B. CONCLUSIONS: The addition of deep breathing exercises to physiotherapy-directed early mobilisation did not further reduce PPCs compared with mobility alone. PPCs can be reduced with once-daily physiotherapy if the patients are mobilised to a moderate level of exertion. Delayed mobilisation tended to increase physiotherapy input and the number of days until discharge from physiotherapy compared with early mobilisation.

Integrating a multidisciplinary mobility programme into intensive care practice (IMMPTP): a multicentre collaborative.

BACKGROUND: ICU immobility can contribute to physical deconditioning, increased ICU and hospital length of stay and complications post discharge. Despite evidence of the beneficial outcomes of early mobility, many ICUs and providers lack necessary processes and resources to effectively integrate early mobility into their daily practice. OBJECTIVE: To create a progressive mobility initiative that will help ICU teams to address key cultural, process and resource opportunities in order to integrate early mobility into daily care practices. METHODS: An initiative to integrate the latest evidence on mobility practice into current ICU culture in 13 ICUs in eight hospitals within the US was launched. A user-friendly, physiologically grounded evidence-based mobility continuum was designed and implemented. Appropriate education and targeted messaging was used to engage stakeholders. To support and sustain the implementation process, mechanisms including coaching calls and various change interventions were offered to modify staffs' practice behaviour. Qualitative data was collected at two time points to assess cultural and process issues around mobility and provided feedback to the stakeholders to support change. Quantitative date on ventilator days and timing of physical therapy consultation was measured. RESULTS: Qualitative reports of the mobility programme participants suggest that the methods used in the collaborative approach improved both the culture and team focus on the process of mobility. There were no significant differences demonstrated in any of the mobility intervention group measurement however, a reduction in ventilator days (3.0days pre vs. 2.1 days post) approached significance (p=0.06). CONCLUSION: This multi-centre, ICU collaborative has shown that improvements in team culture, communication and resources can improve adoption of early mobility in ICU patients.

Enhanced recovery after colon surgery in a community hospital system.

BACKGROUND: Enhanced recovery after colon surgery has not been widely adopted in the United States and Europe, despite evidence that postoperative complications and hospital length of stay are decreased. OBJECTIVE: We sought to evaluate the introduction of a comprehensive care process for enhanced recovery after colon surgery in 8 community hospitals. DESIGN: A system-wide, surgeon-directed, multidisciplinary committee developed a comprehensive enhanced-care quality-improvement program. Surgeons and operations leaders in each hospital developed the internal structure to implement the process. PATIENTS: Surgeons had the option of entering or not entering patients in the enhanced-care pathway. Other than trauma patients, there were no exclusion criteria. MAIN OUTCOME MEASURES: To limit selection bias, the study population included all patients undergoing colon resections (those entered and not entered in the care process). Length of stay, postoperative days, hospital costs, 30-day readmission rate, and return to surgery for the study population were compared with a 2-year historical baseline. RESULTS: Forty-two percent of the study population was entered in the enhanced-care process. The average length of stay and the number of postoperative days in the study population decreased by 1.5 (P < .0001) and 1.3 (P < .0001) days. The rate of readmissions and returns to surgery remained stable (P > .05), and the average hospital cost decreased by $1763 (P = .02). Generalized linear regression analysis demonstrated that the enhanced-care process was a more significant variable than was the surgical approach (laparoscopic vs open surgery) in decreasing length of stay. LIMITATIONS: The degree of compliance with care process elements and the relative contribution of each element of the care process are unknown. CONCLUSIONS: A comprehensive enhanced-care colon surgery care process was successfully introduced in a community hospital system, as indicated by the clinical outcome measures.

[Fast-track paediatric surgery]. / Fast-track-Kinderchirurgie.

Fast-track surgery is a comprehensive perioperative treatment concept that has been successfully performed and widely accepted in adult surgery since the 1990s. The crucial aim is to speed up convalescence and to avoid perioperative complications as pneumonia and thrombosis. Compared to conventional treatment strategies, hospital stays are substantially reduced. In the paediatric field fast-track surgery is not generally established. However, in recent studies a high efficiency of paediatric surgical fast-track procedures with respect to medical, psychological, economical and ethical parameters has been shown. It has been confirmed that early convalescence leads to an increase of satisfaction of the patients and their parents without higher complication rates. Shorter hospital stays lead to reduced expenses for the health insurances and parents. Fast-track concepts are not implemented in the German reimbursement system G-DRG. Thus, problems with intensified nursing and reimbursement remain to be solved.

Technology to enhance physical rehabilitation of critically ill patients.

BACKGROUND: Neuromuscular complications after critical illness are common and can be severe and persistent. To ameliorate complications, there is growing interest in starting physical medicine and rehabilitation therapy immediately after physiologic stabilization. The introduction of physical medicine and rehabilitation-related technology into the intensive care unit may help facilitate delivery of this therapy. DISCUSSION: Neuromuscular electrical stimulation therapy creates passive contraction of muscles through low-voltage electrical impulses delivered through skin electrodes placed over target muscles. Although neuromuscular electrical stimulation has not been studied in patients with acute critical illness, published guidelines based on available evidence suggest that neuromuscular electrical stimulation may be considered in intensive care unit patients who are at high risk of developing muscle weakness. Bedside cycle ergometry can provide range of motion and muscle strength training for intensive care unit patients who are either sedated or awake, and may help preserve muscle architecture and improve strength and function. Finally, custom-designed technological aids to assist with ambulating mechanically ventilated patients may reduce the human resource requirements and improve the safety and effectiveness of early mobilization in the intensive care unit. CONCLUSION: Physical medicine and rehabilitation-related technologies may play an important role in preventing and treating intensive care unit-acquired neuromuscular complications. Future studies are needed to evaluate their efficacy in intensive care unit patients.

Randomised clinical trial of physiotherapy after open abdominal surgery in high risk patients.

Postoperative physiotherapy has been shown to reduce the incidence of postoperative pulmonary complications after open abdominal surgery. This study aimed to determine if the addition of deep breathing exercises and secretion clearing techniques to a standardised physiotherapist-directed program of early mobilisation improved clinical outcomes in patients undergoing open abdominal surgery. Fifty-six patients undergoing open abdominal surgery, at high risk of developing postoperative pulmonary complications, were randomised before operation to an early mobilisation-only group or an early mobilisation-plus-deep breathing and coughing group. Mobility duration, frequency and intensity of breathing interventions were quantified for both groups. All outcomes were assessed by a blinded outcomes researcher using a standardised outcomes measurement tool developed specifically for this population. Outcomes included incidence of clinically significant postoperative pulmonary complications, fever, length of stay, and restoration of mobility. There were no significant differences between groups in mean age, anaesthetic time, perioperative morbidity, or postoperative mobility. Outcome data were available for 89% of enrolled subjects. Overall incidence of postoperative pulmonary complications was 16%. The incidence of postoperative pulmonary complications in the non-deep breathing and coughing group was 14%, and the incidence of postoperative pulmonary complications in the deep breathing and coughing group was 17%, (absolute risk reduction -3%, 95% C1 -22 to 19%). There was no significant difference between groups in the incidence of fever, physiotherapist time, or the number of treatments. This study suggests that, in this clinical setting, the addition of deep breathing and coughing exercises to a physiotherapist-directed program of early mobilisation does not significantly reduce the incidence of clinically significant postoperative pulmonary complications in high risk open abdominal surgery subjects.

Does removal of deep breathing exercises from a physiotherapy program including pre-operative education and early mobilisation after cardiac surgery alter patient outcomes?

The aim of this study was to establish whether removal of breathing exercises from a regimen including early mobilisation changes the incidence of post-operative pulmonary complications for patients after cardiac surgery. Two hundred and thirty patients undergoing open heart surgery at Monash Medical Centre, Melbourne, were enrolled in this randomised controlled trial. All patients received physiotherapy treatment pre-operatively and post-operatively for three days. Patients were mobilised as soon as possible after surgery. Breathing group (control) patients performed a set routine of deep breathing exercises at each physiotherapy visit while those in the intervention group did not perform this routine. Other than the breathing exercises, patient management was similar between groups in terms of assessment, positioning and mobility. The incidence of postoperative pulmonary complications, post-operative length of stay, oxyhaemoglobin saturation and pulmonary function were measured pre-operatively and post-operatively. Intention-to-treat analysis was performed for post-operative pulmonary complications and length of stay. Other data were analysed using t-tests, chi square and repeated measures analysis of variance. There were no significant differences between the groups in the primary dependent variables. It is concluded that removal of breathing exercises from the routine physiotherapy management of open heart surgery patients does not significantly alter patient outcome.

Prevention of permanent arthrofibrosis after anterior cruciate ligament reconstruction alone or combined with associated procedures: a prospective study in 443 knees.

We prospectively determined the effectiveness of an immediate knee motion and early intervention program to prevent permanent motion limitations in a consecutive series of patients who had anterior cruciate ligament autogenous patellar tendon reconstruction for isolated rupture (219 knees) or combined with other procedures (224 knees). The subjects were placed into either a progressive or delayed rehabilitation program and were followed for at least 12 months postoperatively. At follow-up a normal range of motion (0 degrees to at least 135 degrees) was found in 436 knees (98%), and mild losses of extension (-5 degrees) were found in 7 knees. Twenty-three knees (5%) required interventions; 9 had extension casts, 9 had gentle manipulations under anesthesia, 3 had arthroscopic debridements, and 2 had continuous epidural anesthetic and inpatient therapy. All of these 23 knees regained full motion. The 7 patients with mild losses of extension had refused treatment intervention. The 0% incidence rate of permanent arthrofibrosis, and 0.7% reoperation rate for knee motion limitations, demonstrated the effectiveness of our program.
