Abstract
COVID-19, also commonly known as coronavirus, is presently declared a pandemic disease by the World Health Organisation (WHO). This disease is transmitted by close contact with infected patients who are either asymptomatic or symptomatic. About 5% of COVID-19 patients are admitted to the Intensive Care Unit (ICU) and present with either pneumonia or acute respiratory distress syndrome. Chest physiotherapy may be provided to some patients admitted in ICU who may be broadly classified into the following two groups: 1. Patients suspected or infected with COVID-19 with no underlying lung disease (Other than COVID-19) & 2. Patients suspected or infected with COVID-19 with underlying lung disease (Other than COVID-19). Generally, asymptomatic patients do not require chest physiotherapy, but symptomatic patients do. This literature review discusses the various chest physiotherapy techniques related to body positioning, breathing, airway clearance, and mobilization that can be provided to COVID-19 patients admitted to the ICU. More importantly, precautions to be taken by the physiotherapist involved in the care of COVID-19 patients in the ICU have also been reviewed.

Abstract
OBJECTIVES Mechanical ventilation increases the risk of hospital-acquired conditions (HACs) such as ventilator-associated pneumonia (VAP) and pressure injury (PrI). Beds with continuous lateral rotation therapy (CLRT) are shown to reduce HAC incidence, but the value of switching to CLRT beds is presently unknown. We compared the cost-effectiveness of CLRT beds with standard care in intensive care units. METHODS A cost-effectiveness analysis from the healthcare sector and societal perspectives was conducted. A Markov model was constructed to predict health state transitions from time of ventilation through 28 days for the healthcare sector perspective and 1 year for the U.S. societal perspective. Value of information was calculated to determine whether parameter uncertainty warranted further research. RESULTS Our analysis suggested that CLRT beds dominate standard care from both perspectives. From the healthcare sector perspective, expected cost for CLRT was U.S. $47,165/patient compared with a higher cost of U.S. $49,258/patient for standard care. The expected effectiveness of CLRT is 0.0418 quality-adjusted life years/patient compared with 0.0416 quality-adjusted life years/patient for standard care. Continuous lateral rotation therapy dominated standard care in approximately 93% of Monte Carlo simulations from both perspectives. Value of information analysis suggests that additional research is potentially cost-effective. CONCLUSIONS Continuous lateral rotation therapy is highly cost-effective compared with standard care by preventing HACs that seriously harm patients in the intensive care unit.

Abstract
BACKGROUND Patients with severe thoracic trauma often receive continuous lateral rotational bed therapy (CLRT) for the treatment of lung contusions. In this study, the effects of CLRT on mortality, morbidity and length of stay (LOS) in the intensive care unit (ICU) and in the hospital were evaluated. METHODS Retrospective data from the TraumaRegister DGU® were analysed, focusing on patients with severe thoracic trauma. Patients treated with CLRT were compared to a control group with comparable trauma severity who had received conventional therapy. RESULTS A total of 1476 patients (239 with CLRT, 1237 without CLRT) were included in this study. Both groups were similar for demographic characteristics. The median CLRT duration was 6 (4-10) days. Patients receiving CLRT were ventilated for 17 (10-26) days compared to 14 (8-22) days (p = 0.001) in the control group. The ICU length of stay differed significantly (CLRT: 23 [14-32] days; control: 19 [13-28] days; p = 0.002). Also, organ failure occurred more frequently in patients treated with CLRT (CLRT: 76.6%, control: 67.6%; p = 0.006). No differences could be detected regarding mortality rates, multiple organ failure and hospital LOS. CONCLUSIONS The results of this retrospective analysis fail to detect a benefit for CLRT therapy in trauma patients. Considering inherent limitations of retrospective studies, caution should be exerted when interpreting these results. Further research is warranted to confirm these findings in a prospective trial.

Abstract
PURPOSE OF REVIEW To review the current use of continuous lateral rotational therapy (CLRT) in patients with thoracic injuries and its impact on clinical course, complications and outcome. RECENT FINDINGS Patient positioning is a key factor in the treatment of severe thoracic injuries and CLRT, and intermittent supine and prone position are basic options. There is a lack of randomized controlled studies for trauma patients with chest injury undergoing kinetic therapy as standard of care. A positive effect of kinetic therapy for prevention of secondary respiratory complications has been reported; nevertheless, no positive effect on mortality or length of hospital stay could be affirmed so far. In general, standardized therapeutic regimes for treatment of chest trauma have been implemented, including ventilator settings and positioning therapy. However, the available data do not allow a clear recommendation for rotational/kinetic therapy or prone positioning as superior or inferior. SUMMARY The benefit of changing the patients' position for secret mobilization and recruitment of atelectasis after chest trauma and therefore preventing secondary complications seems to be self-evident. Since only few studies report about the utility of CLRT in critically ill chest trauma patients, randomized controlled multicenter trials are necessary to analyze the overall benefit of such means.

Abstract
Even after many years of intensive research acute respiratory distress syndrome (ARDS) is still associated with a high mortality. Epidemiologically, ARDS represents a central challenge for modern intensive care treatment. The multifactorial etiology of ARDS complicates the clear identification and evaluation of new therapeutic interventions. Lung protective mechanical ventilation and adjuvant therapies, such as the prone position and targeted extracorporeal lung support are of particular importance in the treatment of ARDS, depending on the severity of the disease. In order to guarantee an individualized and needs-adapted treatment, ARDS patients benefit from treatment in specialized centers.

Abstract
BACKGROUND Recognizing patients at risk for pulmonary complications (PC) is of high clinical relevance. Migration of polymorphonuclear leukocytes (PMN) to inflammatory sites plays an important role in PC, and is tightly regulated by specific chemokines including interleukin (IL)-8 and other mediators such as leukotriene (LT)B4. Previously, we have reported that LTB4 indicated early patients at risk for PC after trauma. Here, the relevance of LTB4 to indicating lung integrity in a newly established long-term porcine severe trauma model (polytrauma, PT) was explored. METHODS Twelve pigs (3 months old, 30 ± 5kg) underwent PT including standardized femur fracture, lung contusion, liver laceration, hemorrhagic shock, subsequent resuscitation and surgical fracture fixation. Six animals served as controls (sham). After 72h lung damage and inflammatory changes were assessed. LTB4 was determined in plasma before the experiment, immediately after trauma, and after 2, 4, 24 or 72h. Bronchoalveolar lavage (BAL)-fluid was collected prior and after the experiment. RESULTS Lung injury, local gene expression of IL-8, IL-1β, IL-10, IL-18 and PMN-infiltration into lungs increased significantly in PT compared with sham. Systemic LTB4 increased markedly in both groups 4h after trauma. Compared with declined plasma LTB4 levels in sham, LTB4 increased further in PT after 72h. Similar increase was observed in BAL-fluid after PT. CONCLUSIONS In a severe trauma model, sustained changes in terms of lung injury and inflammation are determined at day 3 post-trauma. Specifically, increased LTB4 in this porcine long-term model indicated a rapid inflammatory alteration both locally and systemically. The results support the concept of LTB4 as a biomarker for PC after severe trauma and lung contusion.

Abstract
CONTEXT Osteopathic manipulative treatment (OMT) is a promising adjunctive treatment for older adults hospitalized for pneumonia. OBJECTIVE To report subgroup analyses from the Multicenter Osteopathic Pneumonia Study in the Elderly (MOPSE) relating to hospital length of stay (LOS), ventilator-dependent respiratory failure rate, and in-hospital mortality rate. DESIGN Multicenter randomized controlled trial. SETTING Seven community hospitals. PARTICIPANTS Three hundred eighty-seven patients aged 50 years or older who met specific criteria for pneumonia on hospital admission. INTERVENTIONS Participants were randomly assigned to 1 of 3 groups that received an adjunctive OMT protocol (n=130), a light touch (LT) protocol (n=124), or conventional care only (CCO) (n=133). MAIN OUTCOME MEASURES Outcomes for subgroup analyses were LOS, ventilator-dependent respiratory failure rate, and in-hospital mortality rate. Subgroups were age (50-74 years or ≥75 years), Pneumonia Severity Index (PSI) class (I-II, III, IV, or V), and type of pneumonia (community-acquired or nursing-home acquired). Data were analyzed by intention-to-treat and per-protocol analyses using stratified Cox proportional hazards models and Cochran-Mantel-Haenszel tests for general association. RESULTS By per-protocol analysis of the younger age subgroup, LOS was shorter for the OMT group (median, 2.9 days; n=43) than the LT (median, 3.7 days; n=45) and CCO (median, 4.0 days; n=65) groups (P=.006). By intention-to-treat analysis of the older age subgroup, in-hospital mortality rates were lower for the OMT (1 of 66 [2%]) and LT (2 of 68 [3%]) groups than the CCO group (9 of 67 [13%]) (P=.005). By per-protocol analysis of the PSI class IV subgroup, the OMT group had a shorter LOS than the CCO group (median, 3.8 days [n=40] vs 5.0 days [n=50]; P=.01) and a lower ventilator-dependent respiratory failure rate than the CCO group (0 of 40 [0%] vs 5 of 50 [10%]; P=.05). By intention-to-treat analysis, in-hospital mortality rates in the PSI class V subgroup were lower (P=.05) for the OMT group (1 of 22 [5%]) than the CCO group (6 of 19 [32%]) but not the LT group (2 of 15 [13%]). CONCLUSION Subgroup analyses suggested adjunctive OMT for pneumonia reduced LOS in adults aged 50 to 74 years and lowered in-hospital mortality rates in adults aged 75 years or older. Adjunctive OMT may also reduce LOS and in-hospital mortality rates in older adults with more severe pneumonia. Interestingly, LT also reduced in-hospital mortality rates in adults aged 75 years or older relative to CCO. (ClinicalTrials.gov number NCT00258661).

Abstract
The contemporary management of infectious diseases is built around antimicrobial therapy. However, the development of antimicrobial resistance threatens to create a post-antibiotic era. Antimicrobial stewardship attempts to reduce the development of antimicrobial resistance by improving their appropriate use. Osteopathic manipulative treatment as an adjunctive treatment has the potential for enhancing antimicrobial stewardship by enhancing the human immune system, shortening the duration of antimicrobial therapy, reducing complications, and improving treatment outcomes. The present article reviews the evidence published in the literature since this unique treatment approach was first developed more than 100 years ago. The evidence suggests that adjunctive osteopathic manipulative treatment has great potential for enhancing antimicrobial stewardship and should be further investigated.

Abstract
Extracorporeal membrane oxygenation (ECMO) has been used to provide "lung rest" through the use of low tidal volume (6 ml/kg) and ultralow tidal volume (<6 ml/kg) ventilation in acute respiratory distress syndrome (ARDS). Low and ultralow tidal volume ventilation can result in low dynamic respiratory compliance and potentially increased retention of airway secretions. We present our experience using automated rotational percussion beds (ARPBs) and bronchoscopy in four ARDS patients to manage increased pulmonary secretions. These beds performed automated side-to-side tilt maneuver and intermittent chest wall percussion. Their use resulted in substantial reduction in peak and plateau pressures in two patients on volume control ventilation, while the driving pressures (inspiratory pressure) to attain the desired tidal volumes in patients on pressure control ventilation also decreased. In addition, mean partial pressure of oxygen in arterial blood (PaO2)/fraction of inspired oxygen (FiO2) ratio (109 pre-ARPB vs. 157 post-ARPB), positive end-expiratory pressure (10 cm H2O vs. 8 cm H2O), and FiO2 (0.88 vs. 0.52) improved after initiation of ARPB. The improvements in the respiratory mechanics and oxygenation helped us to initiate early ECMO weaning. Based on our experience, the use of chest physiotherapy, frequent body repositioning, and bronchoscopy may be helpful in the management of pulmonary secretions in patients supported with ECMO.

Abstract
BACKGROUND The purpose of this study was to evaluate the impact of continuous lateral rotational therapy (CLRT) on respiratory complications and mortality in patients suffering from trauma. METHODS The literature databases PubMed®/Medline® and the Cochrane Library® were systematically searched for prospective controlled trials comparing continuous lateral rotational therapy to conventional manual positioning in trauma patients. RESULTS A total of 8 publications (n= 422 patients) with comparable age and injury severity were included in the meta-analysis. A significant reduction in the incidence of nosocomial pneumonia (OR: 0.33, [95%CI: 0.17, 0.65], p=0.001) was observed in patients treated prophylactically with continuous lateral rotational therapy. When used with therapeutic intention, CLRT had no impact on the incidence of pneumonia. There were no significant differences in mortality, duration of mechanical ventilation, or ICU length of stay. CONCLUSIONS Analogous to studies evaluating CLRT in medical or mixed patient collectives, CLRT reduced the rates of nosocomial pneumonia in trauma patients. This, however, had no impact on overall mortality. The level of evidence of the studies included was limited by several factors. An adequately powered, well-designed multi-centre randomised controlled trial is required, to validly assess the utility of CLRT for the prevention and treatment of pulmonary complications in patients suffering from trauma. LEVEL OF EVIDENCE Systematic review and meta-analysis, level III.

Abstract
The German Society of Anesthesiology and Intensive Care Medicine (DGAI) commissioned a revision of the S2 guidelines on "positioning therapy for prophylaxis or therapy of pulmonary function disorders" from 2008. Because of the increasing clinical and scientific relevance the guidelines were extended to include the issue of "early mobilization" and the following main topics are therefore included: use of positioning therapy and early mobilization for prophylaxis and therapy of pulmonary function disorders, undesired effects and complications of positioning therapy and early mobilization as well as practical aspects of the use of positioning therapy and early mobilization. These guidelines are the result of a systematic literature search and the subsequent critical evaluation of the evidence with scientific methods. The methodological approach for the process of development of the guidelines followed the requirements of evidence-based medicine, as defined as the standard by the Association of the Scientific Medical Societies in Germany. Recently published articles after 2005 were examined with respect to positioning therapy and the recently accepted aspect of early mobilization incorporates all literature published up to June 2014.

Abstract
BACKGROUND Critically ill patients require regular body position changes to minimize the adverse effects of bed rest, inactivity and immobilization. However, uncertainty surrounds the effectiveness of lateral positioning for improving pulmonary gas exchange, aiding drainage of tracheobronchial secretions and preventing morbidity. In addition, it is unclear whether the perceived risk levied by respiratory and haemodynamic instability upon turning critically ill patients outweighs the respiratory benefits of side-to-side rotation. Thus, lack of certainty may contribute to variation in positioning practice and equivocal patient outcomes. OBJECTIVES To evaluate effects of the lateral position compared with other body positions on patient outcomes (mortality, morbidity and clinical adverse events) in critically ill adult patients. (Clinical adverse events include hypoxaemia, hypotension, low oxygen delivery and global indicators of impaired tissue oxygenation.) We examined single use of the lateral position (i.e. on the right or left side) and repeat use of the lateral position (i.e. lateral positioning) within a positioning schedule. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL; 2015, Issue 5), MEDLINE (1950 to 23 May 2015), the Cumulative Index to Nursing and Allied Health Literature (CINAHL) (1937 to 23 May 2015), the Allied and Complementary Medicine Database (AMED) (1984 to 23 May 2015), Latin American Caribbean Health Sciences Literature (LILACS) (1901 to 23 May 2015), Web of Science (1945 to 23 May 2015), Index to Theses in Great Britain and Ireland (1950 to 23 May 2015), Trove (2009 to 23 May 2015; previously Australasian Digital Theses Program (1997 to December 2008)) and Proquest Dissertations and Theses (2009 to 23 May 2015; previously Proquest Digital Dissertations (1980 to 23 May 2015)). We handsearched the reference lists of potentially relevant reports and two nursing journals. SELECTION CRITERIA We included randomized and quasi-randomized trials examining effects of lateral positioning in critically ill adults. We included manual or automated turns but limited eligibility to studies that included duration of body position of 10 minutes or longer. We examined each lateral position versus at least one comparator (opposite lateral position and/or another body position) for single therapy effects, and the lateral positioning schedule (repeated lateral turning) versus other positioning schedules for repetitive therapy effects. DATA COLLECTION AND ANALYSIS We pre-specified methods to be used for data collection, risk of bias assessment and analysis. Two independent review authors carried out each stage of selection and data extraction and settled differences in opinion by consensus, or by third party adjudication when disagreements remained unresolved. We planned analysis of pair-wise comparisons under composite time intervals with the aim of considering recommendations based on meta-analyses of studies with low risk of bias. MAIN RESULTS We included 24 studies of critically ill adults. No study reported mortality as an outcome of interest. Two randomized controlled trials (RCTs) examined lateral positioning for pulmonary morbidity outcomes but provided insufficient information for meta-analysis. A total of 22 randomized trials examined effects of lateral positioning (four parallel-group and 18 cross-over designs) by measuring various continuous data outcomes commonly used to detect adverse cardiopulmonary events within critical care areas. However, parallel-group studies were not comparable, and cross-over studies provided limited data as the result of unit of analysis errors. Eight studies provided some data; most of these were single studies with small effects that were imprecise. We pooled partial pressure of arterial oxygen (PaO2) as a measure to detect hypoxaemia from two small studies of participants with unilateral lung disease (n = 19). The mean difference (MD) between lateral positions (bad lung down versus good lung down) was approximately 50 mmHg (MD -49.26 mmHg, 95% confidence interval (CI) -67.33 to -31.18; P value < 0.00001). Despite a lower mean PaO2 for bad lung down, hypoxaemia (mean PaO2 < 60 mmHg) was not consistently reported. Furthermore, pooled data had methodological shortcomings with unclear risk of bias. We had similar doubts regarding internal validity for other studies included in the review. AUTHORS' CONCLUSIONS Review authors could provide no clinical practice recommendations based on the findings of included studies. Available research could not eliminate the uncertainty surrounding benefits and/or risks associated with lateral positioning of critically ill adult patients. Research gaps include the effectiveness of lateral positioning compared with semi recumbent positioning for mechanically ventilated patients, lateral positioning compared with prone positioning for acute respiratory distress syndrome (ARDS) and less frequent changes in body position. We recommend that future research be undertaken to address whether the routine practice of repositioning patients on their side benefits all, some or few critically ill patients.

Abstract
[Purpose] The purpose of this study was to examine the pressure-relieving effects of a continuous lateral turning device on common pressure ulcer sites. [Subjects] Twenty-four healthy adults participated. [Methods] The design of our continuous lateral turning device was motivated by the need for an adequate pressure-relieving device for immobile and/or elderly people. The procedure of manual repositioning is embodied in our continuous lateral turning device. The interface pressure and time were measured, and comfort grade was evaluated during sessions of continuous lateral turning at 0°, 15°, 30°, and 45°. We quantified the pressure-relieving effect using peak pressure, mean pressure, and pressure time integration. [Results] Participants demonstrated pressure time integration values below the pressure-time threshold at 15°, 30°, and 45° at all the common pressure ulcer sites. Moreover, the most effective angles for pressure relief at the common pressure ulcer sites were 30° at the occiput, 15° at the left scapula, 45° at the right scapula, 45° at the sacrum, 15° at the right heel, and 30° at the left heel. However, angles greater than 30° induced discomfort. [Conclusion] Continuous lateral turning with our specially designed device effectively relieved the pressure of targeted sites. Moreover, the suggested angles of continuous lateral turning can be used to relieve pressure at targeted sites.

Abstract
The German Society of Anesthesiology and Intensive Care Medicine (DGAI) commissioneda revision of the S2 guidelines on "positioning therapy for prophylaxis or therapy of pulmonary function disorders" from 2008. Because of the increasing clinical and scientificrelevance the guidelines were extended to include the issue of "early mobilization"and the following main topics are therefore included: use of positioning therapy and earlymobilization for prophylaxis and therapy of pulmonary function disorders, undesired effects and complications of positioning therapy and early mobilization as well as practical aspects of the use of positioning therapy and early mobilization. These guidelines are the result of a systematic literature search and the subsequent critical evaluation of the evidence with scientific methods. The methodological approach for the process of development of the guidelines followed the requirements of evidence-based medicine, as defined as the standard by the Association of the Scientific Medical Societies in Germany. Recently published articles after 2005 were examined with respect to positioning therapy and the recently accepted aspect of early mobilization incorporates all literature published up to June 2014.

[PMID: 25457336 DOI: 10.1016/j.injury.2014.10.049] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/23/2014] [Revised: 05/22/2014] [Accepted: 10/14/2014] [Indexed: 02/02/2023]
Abstract
INTRODUCTION Bedrest is often used for temporary management, as well as definitive treatment, for many spinal injuries. Under such circumstances patients cannot remain flat for extended periods due to possible skin breakdown, blood clots, or pulmonary complications. Kinetic therapy beds are often used in the critical care setting, although this is felt to be unsafe for turning patients with spine fractures. We sought to evaluate whether a kinetic therapy bed would cause as much spinal motion at an unstable cervical injury as occurs during manual log-rolling on a standard intensive care unit bed. METHODS Unstable C5-C6 ligamentous injuries were surgically created in 15 fresh, whole cadavers. Sensors were affixed to C5 and C6 posteriorly and electromagnetic motion tracking analysis performed. In all cases a cervical collar was applied by an orthotist after creation of the injury. The amount of angular motion and linear displacement that occurred at this injured level was measured during manual log-rolling and patient turning using a kinetic therapy bed. For statistical analysis, the range of motion for angles about each axis and displacement in each direction was analyzed by multivariate analysis of variance with repeated measures. RESULTS When comparing manual log-rolling and kinetic bed therapy, significantly more angular motion was created by the log-roll manoeuvre in flexion-extension (p=0.03) and lateral bending (p=0.01). There was no significant difference in axial rotation between the two methods (p=0.80). There were no significant differences demonstrated in medial-lateral and anterior-posterior translation. There was almost two times the axial displacement between manual log-rolling and the kinetic therapy bed and this reached statistical significance (p=0.05). CONCLUSION There is less motion at an unstable cervical injury in flexion-extension, lateral bending, and axial displacement when turning a patient using a kinetic therapy bed as opposed to traditional manual log-rolling. It may be preferable to use a kinetic therapy bed rather than manual log-rolling for patients with cervical spine injuries to decrease unwanted spinal motion. In addition, it may be easier and less physically demanding on nursing staff that must regularly turn the patient if manual log-rolling is implemented.

Abstract
Post stroke infections are a significant clinical problem. Dysphagia occurs in approximately half of stroke patients and is associated with respiratory infections; however it is unclear what other factors contribute to an increased risk. This study aimed to determine which factors are most strongly predictive of infections in the first 7 days post stroke admission. A retrospective review of 536 stroke patients admitted to Australian hospitals in 2010 was conducted. Data were collected on 37 clinical and demographic parameters. Univariate and multivariate logistic regression analysis was performed. The overall incidence of infection was 21%. Full assistance with mobility and incontinence on admission were associated with increased odds of general infection. Nil by mouth and presence of a nasogastric tube were significantly associated with patients developing respiratory infections. Urinary incontinence was a significant predictor for a urinary tract infection. Incidence of infection was highest on day two post admission. This study found enteral feeding, requiring full assistance with mobility and incontinence were significantly associated with developing infections in acute stroke. It contributes valuable new data from a large cohort of stroke patients demonstrating a period of susceptibility to infection in the very acute post stroke period.

Abstract
Professional experience and wisdom have taught us that immobility is a risk factor for various adverse outcomes, such as deep vein thrombosis, joint contractures, pulmonary dysfunction, and bone demineralization to name a few. Balancing bed rest and mobility may improve both short- and long-term outcomes for our patients. Moreover, early, routine mobilization of critically ill patients is safe and reduces hospital length of stay, shortens the duration of mechanical ventilation, improves muscle strength, and functional independence. At the University of Michigan, we have turned the tides by creating a structured process to get our patients moving through the use of a standardized mobility protocol. Our protocol is simple and can easily be adapted for all patient populations by simply modifying some of the inclusion and exclusion criteria. The activities are grounded in the evidence and well thought out to prevent complications and promote mobilization. The purpose of this article was to present the science behind the development of a multidisciplinary protocol for early mobilization of critically ill patients that can be adapted to any intensive care unit patient with minor modifications.

Abstract
Background The preoperative coexisting chronic systemic illness, delay in surgery, gender, and age were considered as risk factors for the complications after hip fracture surgery. The wider range of surgical delay and immobility-related pulmonary morbidity may affect postoperative complications and mortality. This study examined the risk factors for morbidity and mortality following the hip fracture surgery. Methods The patient data was collected retrospectively. The consecutive 506 patients with hip fracture surgery, aged 60 years or older, were included. The patients' age, gender, preexisting diseases, American Society of Anesthesiologists (ASA) classification, delay in surgical repair, duration of surgical procedure, and methods of anesthesia were noted. The thirty-day postoperative complications were reviewed, and cardiac complications, pulmonary complications, delirium, and death were recorded. The data was analyzed for postoperative complications and risk factors. Results Atelectasis was associated with postoperative pulmonary complications. Male gender and age ≥ 80 years were associated with an increased incidence of postoperative delirium. ASA classification 3 was associated with death. A delay in surgery was not associated with any complications. Preexisting diseases and methods of anesthesia did not affect mortality and postoperative complications. Conclusions The results suggest that a delay in surgery did not affect the postoperative complications and morbidity.

Abstract
BACKGROUND Patients with severe, multiple, traumatic injuries are challenging to manage in critical care. Early identification of injuries and optimal resuscitation is essential for favourable outcomes. Trauma-related haemorrhage can lead to the lethal triad of hypothermia, coagulopathy and acidosis. Many trauma patients require urgent haemorrhage control and structural fixation through operative intervention. However, metabolic derangement and cardiovascular instability may delay surgery, resulting in an ongoing cycle of deterioration. Damage control surgery (DCS) may be used as a temporizing measure until the patient is stabilized in critical care. The aim of this case study is to discuss the complex issues faced in the critical care management of a severely injured patient. DESIGN We conducted a patient case study, with analysis of care using published evidence. The key terms used to search for evidence were trauma, injury, damage control surgery, spinal fixation, critical/intensive care and nurse. RESULTS We report the care of a trauma patient with complex, conflicting injuries requiring management of the lethal triad and DCS. The delay in subsequent definitive repair of spinal column fractures provided many challenges for critical care nurses including restricted patient mobilization, positioning and pressure ulcer prevention. A review of contemporary evidence relating to DCS reveals that whilst this technique is used increasingly in trauma, the research focuses on single system injuries. CONCLUSION Evidence and guidelines are required to support DCS for critical care patients with multiple, conflicting injuries including spinal fractures. For patients with delayed surgical intervention, rotational bed therapy may assist critical care nurses in meeting needs.

Abstract
Hospital-acquired infections (HAIs) are common in intensive care unit (ICU) patients and are associated with increased morbidity and mortality. There has been an increasing effort to prevent HAIs, and infection control practices are paramount in avoiding these complications. In the last several years, numerous developments have been seen in the infection prevention strategies in various health care settings. This article reviews the modern trends in infection control practices to prevent HAIs in ICUs with a focus on methods for monitoring hand hygiene, updates in isolation precautions, new methods for environmental cleaning, antimicrobial bathing, prevention of ventilator-associated pneumonia, central line-associated bloodstream infections, catheter-associated urinary tract infections, and Clostridium difficile infection.

Rotational bed therapy after blunt chest trauma: a nationwide online-survey on current concepts of care in Germany. Injury 2013; 44:70-4.

Abstract
INTRODUCTION Blunt chest injuries are amongst the most life threatening injuries in adult multiple trauma patients. Nevertheless, the treatment of these thoracic injuries has not been standardized yet. Previous publications have reported on the prevention and the treatment of respiratory complications by using continuous lateral rotational bed therapy (CLRT), but there is still a lack of information using this approach in the presence of pulmonary contusions. Therefore current literature indicates a variety of treatment protocols and its use is contended. METHODS We submitted a 32-item online-questionnaire to 155 hospitals participating in the nationwide TraumaNetwork to assess current treatment concepts in multiple trauma patients suffering from blunt chest trauma including lung contusions with particular focus on the use of CLRT. Overall, 21 level I, 53 level II and 81 level III trauma centres were contacted. The questionnaire was created using "interview 123 5.5.b.de ND6". RESULTS The overall response rate was 35.5% (55/155) and responses were received from 10 level I (47.6%), 17 level II (32.1%) and 24 level III (29.6%) trauma centres. Thirty-five of the responders (63.6%) declared to be able to perform lateral rotational bed therapy. For level I and II trauma centres more than 80% were able to apply kinetic positioning in contrast to only 50% of level III trauma centres. Although 42.9% of the participants reported on the existence of standardized treatment protocols, 57.1% failed to report a standardized operating procedure for CLRT. The annual mean number of patients per centre treated via CLRT was 15 (0-130). Treatment modalities such as PEEP and the duration of CLRT also showed great variability. Against this background three out of four centres declared an urgent need for further clinical research in the field. CONCLUSIONS Our data reflect the wide range of different CLRT treatment strategies performed for blunt pulmonary trauma involving lung contusions in German trauma centres. We conclude that a high-quality randomized-controlled trial is warranted to critically assess the role of CLRT in multiple trauma patients with blunt chest trauma to provide a sound basis for future clinical guidelines.

Abstract
BACKGROUND The incidence of posttraumatic acute lung injury is high and may result in increased mortality. Changes in the body position are additional measures to improve pulmonary gas exchange and to prevent pulmonary complications. We investigated the effect of a continuous lateral rotational therapy (CLRT) on the inflammatory response in patients with posttraumatic lung failure. METHODS After admission to the intensive care unit (ICU) and after randomisation, 13 patients were placed in a special motor-driven bed and CLRT was performed for 5 days. In the control group (n=14), patients were positioned conventionally. Samples from blood and from broncho-alveolar lavage fluid (BAL) were collected in both groups before study began and on day 5. The levels of cytokines (Tumour Necrosis Factor, Interleukin 6, Interleukin 8 or Intercellular Adhesion Molecule-1) were assessed and haemodynamic, pulmonary, and laboratory values were documented. RESULTS On day 5, no significant differences were found in cytokine levels between groups, but a significant decrease in IL-8 (p<0.01) and TNF-α (p<0.05) serum levels and an increase in IL-8 BAL levels was found in the CLRT-group, but not for conventionally managed patients. In general cytokine BAL levels tended to be increased in both groups, but more pronounced during CLRT. Daily assessment of the severity of disease (SAPS-II, SOFA) was significantly reduced in the study group on days 2-4 (p<0.05) in comparison to control group. CONCLUSIONS CLRT may attenuate the inflammatory response to posttraumatic acute lung injury. The exact mechanism of such an effect is unknown.

Abstract
BACKGROUND Pulmonary complications are common in multiple trauma patients with chest injury. Factors predisposing these critically ill patients to respiratory organ failure are not fully understood. METHODS Univariate and multivariate logistic regression analyses were used to assess the prognostic value of clinical and laboratory variables (2002-2008; n = 30,616) from the Trauma Registry of the German Trauma Society (DGU). Data from patients admitted to the ICU with lung contusion/lacerations, an Injury Severity Score ≥ 16 and age ≥ 18 were included in the study. Severe pulmonary organ failure was defined as PaO(2)/FiO(2)<200 for ≥ 3 days and based on the odds ratios (ORs) a simplified Lung Organ Failure Score (LOFS) was developed using integer values. RESULTS 21.3% (1254) of the 5892 patients analysed developed severe pulmonary organ failure. We identified seven independent predictors with significant correlation: age, gender, head injury, fluid therapy, injury severity, degree of chest trauma and surgical interventions. The highest ORs were observed in cases of Abbreviated Injury Scale (AIS)(Thorax) = 5 (1.58), surgical intervention (1.71) and multiple surgeries (2.41). We found that patients with simplified score values ≥ 21 points were at a maximum risk (>30%) for developing severe pulmonary complications. CONCLUSION This scoring method could help trauma surgeons determine which multiple trauma patients are at risk for pulmonary complications after trauma. Efficacy analyses of prophylactic PEEP ventilation or rotational bed therapy in subgroups with comparable risks for respiratory complication could be based on the LOFS.

Abstract
Object
The detrimental effects of immobility on intensive care unit (ICU) patients are well established. Limited studies involving medical ICUs have demonstrated the safety and benefit of mobility protocols. Currently no study has investigated the role of increased mobility in the neurointensive care unit population. This study was a single-institution prospective intervention trial to investigate the effectiveness of increased mobility among neurointensive care unit patients.
Methods
All patients admitted to the neurointensive care unit of a tertiary care center over a 16-month period (April 2010 through July 2011) were evaluated. The study consisted of a 10-month (8025 patient days) preintervention observation period followed by a 6-month (4455 patient days) postintervention period. The intervention was a comprehensive mobility initiative utilizing the Progressive Upright Mobility Protocol (PUMP) Plus.
Results
Implementation of the PUMP Plus increased mobility among neurointensive care unit patients by 300% (p < 0.0001). Initiation of this protocol also correlated with a reduction in neurointensive care unit length of stay (LOS; p < 0.004), hospital LOS (p < 0.004), hospital-acquired infections (p < 0.05), and ventilator-associated pneumonias (p < 0.001), and decreased the number of patient days in restraints (p < 0.05). Additionally, increased mobility did not lead to increases in adverse events as measured by falls or inadvertent line disconnections.
Conclusions
Among neurointensive care unit patients, increased mobility can be achieved quickly and safely with associated reductions in LOS and hospital-acquired infections using the PUMP Plus program.

Abstract
BACKGROUND Routine lateral turning of patients has become an accepted standard of care to prevent complications of immobility. The haemodynamic and oxygenation effects for patients in both lateral positions (45°) are still a matter of debate. We aimed to study the effect of these positions on blood pressure, heart rate and oxygenation in a general intensive care population. DESIGN Observational study. METHOD Twenty stable intensive care unit patients had intra-arterial blood pressure recordings in the supine and lateral positions with the correction of hydrostatic height compared with a fixed reference point (phlebostatic level). A multilevel model was used to analyse the data. RESULTS Mean arterial pressure readings in the lateral positions were, on average, 5 mmHg higher than in the supine position (p < 0.001). There were no significant differences between mean arterial pressure recordings in the left and right lateral position (p = 1.0). No important differences in oxygenation and heart rate were observed. After correction for covariates, the effects persisted. CONCLUSION Our study demonstrated an increase, albeit small, in blood pressure in the lateral positions. No major differences between the left and right lateral position were found. No important differences in oxygenation and heart rate were observed. RELEVANCE TO CLINICAL PRACTICE Turning haemodynamically stable patients in the intensive care unit has no important effects on blood pressure measurements when continuous hydrostatic height correction is applied.

Abstract
AIMS This article reviews the current evidence, benefits and drawbacks for the use of continuous lateral replacement therapy in the treatment and prevention of nosocomial infections in the ventilated patient. RELEVANT TO PRACTICE The acquisition of nosocomial infections and the development of pressure sores continue to be major issues in the care of the critically ill, ventilated patient. The use of continuous lateral rotation therapy (CLRT) as an adjunct in the prevention and treatment of pneumonia has increased in popularity in recent years. A number of institutions routinely advocate the use of CLRT in critically ill patients. CONCLUSION While there is some data to suggest that CLRT may have an impact on prevention of and treatment for nosocomial infections acquired by ventilated patients, there still remains insufficient evidence to its inclusion as a fully validated treatment. Clearly, there is a requirement for more robust, in-depth research into the efficacy of this proposed treatment.

Abstract
Along with the well-known pharmacological and technological advances in the treatment of the critically ill, nurses have made significant contributions in the realm of more holistic approaches to care, advancing well-known nursing therapies such as physical activity, music, and relationship-based care. The purpose of this article is to review current literature regarding adjunctive therapies used for the care for the critically ill, and, by extension, the chronically critically ill. The review describes the application of interventions using physical activity, spirituality, music, complementary and alternate therapies, relationship-focused care, and pet visitation. The authors conducted a multidisciplinary review of literature published between 1990 and 2009, using the Cochrane Database system and PubMed. The main focus was intervention studies; articles in which authors reviewed evidence and made suggestions for practice or further research were also examined.

Abstract
The treatment of severely injured trauma patients (polytrauma) is one of the outstanding challenges in medical care. Early in the initial course the patient's diagnostics have to be scrupulously reevaluated by an interdisciplinary team (tertiary trauma survey) to reduce deleterious sequelae of missed injuries after the initial assessment. Severely injured patients stay in intensive care for an average of 11 days. During this time the patient's therapy has to ensure a high quality evidence-based intensive care treatment and simultaneously has to be tailored to the current individual injuries. Because of the fact that the damage control strategy is gaining increasing acceptance, the intensive care unit plays a pivotal role in the critical time between emergency and elective surgery. Therefore a close cooperation between physicians of the intensive care unit and all surgical disciplines involved is essential to reach the aim of therapeutic efforts. After survival of emergency treatment patients with severe trauma should be reintegrated into social and occupational life as soon as possible.

Abstract
OBJECTIVE To investigate the impact of prophylactic continuous lateral rotation therapy on the prevalence of ventilator-associated pneumonia, duration of mechanical ventilation, length of stay, and mortality in critically ill medical patients. DESIGN Prospective, randomized, clinical study. SETTING Three medical intensive care units of an university tertiary care hospital. PATIENTS Patients were randomized to continuous lateral rotation therapy or standard care if they were mechanically ventilated for <48 hrs and free from pneumonia. Primary study end point was development of ventilator-associated pneumonia. Ventilator-associated pneumonia was defined as infiltrate on the chest radiograph plus newly developed purulent tracheal secretion plus increasing signs of inflammation. The diagnosis had to be confirmed microbiologically and required the growth of a pathogen >10(4) colony-forming units/mL in bronchoalveolar lavage. Radiologists were blinded to randomization whereas clinical outcome assessors were not. INTERVENTIONS Rotation therapy was performed continuously in a specially designed bed over an arc of 90 degrees. Additional measures to prevent ventilator-associated pneumonia were equally standardized in both groups including semirecumbent position. MEASUREMENTS AND MAIN RESULTS Ventilator-associated pneumonia frequency during the intensive care unit stay was 11% in the rotation group and 23% in the control group (p = .048), respectively. Duration of ventilation (8 +/- 5 vs. 14 +/- 23 days, p = .02) and length of stay (25 +/- 22 days vs. 39 +/- 45 days, p = .01) were significantly shorter in the rotation group. In a forward stepwise logistic regression model including the continuous lateral rotation therapy, gender, Lung Injury Score, and Simplified Acute Physiology Score II, continuous lateral rotation therapy just failed to reach statistical significance with respect to development of ventilator-associated pneumonia (p = .08). Intolerance to continuous lateral rotation therapy during the weaning phase was observed in 29 patients (39%). Mortality was comparable in both groups. CONCLUSIONS Ventilator-associated pneumonia prevalence was significantly reduced by continuous lateral rotation therapy. Continuous lateral rotation therapy led to shorter ventilation time and length of stay. Continuous lateral rotation therapy should be considered in ventilated patients at risk for ventilator-associated pneumonia as a feasible method exerting additive effects to other preventive measures.

Abstract
Previous studies have indicated a positive impact of continuous lateral rotational therapy on nosocomial pneumonia, but have shown mixed results in decreasing length of stay or ventilator days. The objective of the study was to determine if the use of a continuous lateral rotational therapy protocol would decrease mortality and morbidity, mean ventilator days, and/or intensive care unit and hospital length of stay in patients with a pulmonary diagnosis. The study also analyzed the effect of the lag time to the initiation of therapy. Prospectively enrolled subjects receiving continuous lateral rotational therapy based on predetermined indications were compared with retrospectively identified control subjects who met the same inclusion criteria from a similar time period in the previous year. Early initiation of continuous lateral rotational therapy resulted in significant decreases in ventilator days and intensive care unit length of stay. The therapeutic benefit of continuous lateral rotational therapy may be enhanced with early identification and treatment of appropriate patients.

Abstract
Prolonged bed rest is common in critically ill patients, and therapeutic positioning is important to prevent further complications and to improve patient outcomes. Nurses use therapeutic positioning to prevent complications of immobility. This article reviews therapeutic positions including stationary positions (supine, semirecumbent with head of bed elevation, lateral, and prone) and active repositioning (manual, continuous lateral rotation, and kinetic therapy). The physiological rationale and current evidence for each position are described. Applicable evidence-based practice guidelines are summarized. Special considerations for therapeutic positioning of critically ill obese and elderly patients are also discussed.

Abstract
Previously published guidelines are available that provide comprehensive recommendations for detecting and preventing healthcare-associated infections. The intent of this document is to highlight practical recommendations in a concise format designed to assist acute care hospitals in implementing and prioritizing their ventilator-associated pneumonia (VAP) prevention efforts. Refer to the Society for Healthcare Epidemiology of America/Infectious Diseases Society of America “Compendium of Strategies to Prevent Healthcare-Associated Infections” Executive Summary and Introduction and accompanying editorial for additional discussion.1. Occurrence of VAP in acute care facilities.a. VAP is one of the most common infections acquired by adults and children in intensive care units (ICUs).i. In early studies, it was reported that 10%-20% of patients undergoing ventilation developed VAP. More-recent publications report rates of VAP that range from 1 to 4 cases per 1,000 ventilator-days, but rates may exceed 10 cases per 1,000 ventilator-days in some neonatal and surgical patient populations. The results of recent quality improvement initiatives, however, suggest that many cases of VAP might be prevented by careful attention to the process of care.2. Outcomes associated with VAPa. VAP is a cause of significant patient morbidity and mortality, increased utilization of healthcare resources, and excess cost.i. The mortality attributable to VAP may exceed 10%.ii. Patients with VAP require prolonged periods of mechanical ventilation, extended hospitalizations, excess use of antimicrobial medications, and increased direct medical costs.

Abstract
BACKGROUND Significant pulmonary complications are prevalent in intubated and mechanically ventilated patients. OBJECTIVES This study was conducted to determine the impact of continuous lateral rotation therapy (CLRT) on patients considered to be at high risk for pulmonary complications. Overall study objectives included hospital length of stay, critical care length of stay, ventilator days, and cost to treat. METHODS Patients at risk for pulmonary complications as defined by Pao2/Fio2 ratio < 300, Fio2 > 50% for more than 1 hour, positive end-expiratory pressure > or = 8, or a Predicus score of > or = 5 were compared with a historical comparison group that met the high-risk criteria given above and did not receive CLRT. Patients who received CLRT were separated into 2 groups, early CLRT group (began therapy within 48 hours, n = 49) or late CLRT group (n = 46). RESULTS The early CLRT group had a reduction in critical care LOS, (P = .04) as compared with the non-CLRT group. Total hospital costs were reduced (P = .01) in the early intervention group compared to the late intervention group, as well as ICU LOS (P = .02). Nonsignificant trends were seen in reduced ventilator days and hospital LOS. Reintubation rates and readmissions to critical care were also lower in the early intervention group. CONCLUSIONS Continuous lateral rotation therapy, when introduced early in course of treatment of high-risk patients, reduces critical care LOS and cost to treat.

Abstract
BACKGROUND The ventilator-associated pneumonia incident proportion (VAP-IP) is highly variable among control groups of studies of methods for its prevention. The objective here is to develop and validate a literature-derived benchmark against which these groups can be profiled. METHODS A literature search yielded 95 cohort groups and control and intervention groups of 150 studies of either non-antimicrobial or antimicrobial methods of VAP prevention. The 95 cohort groups comprise a benchmark set (30 groups), from which the reference funnel plot (RFP) was derived, and a search set (65 groups), against which the benchmark was validated. The VAP-IP data of the benchmark set were found in five published systematic reviews, whereas the VAP-IP data of the search set were abstracted directly from the literature. FINDINGS Among the 95 cohort groups, the VAP-IP of groups with size >399 was significantly lower than the VAP-IP of smaller groups. Compared with the RFP, 15 of 51 (29%) control groups from studies of antimicrobial methods of VAP prevention with concurrent design were high outlier versus 2 of 110 (2%) control groups from other types of study design (P < 0.001). There were only 22 (14%) outlier groups, all low outlier, among the 162 intervention groups. CONCLUSIONS Study design factors such as concurrency and study size have potentially greater influence on the VAP-IP than do the VAP prevention methods under study. The outlier status of control groups were inapparent in the individual studies and the meta-analyses and yet would have confounded the estimates of treatment effect.
