Abstract
The guideline update outlines the advantages as well as the limitations of NIV in the treatment of acute respiratory failure in daily clinical practice and in different indications.Non-invasive ventilation (NIV) has a high value in therapy of hypercapnic acute respiratory failure, as it significantly reduces the length of ICU stay and hospitalization as well as mortality.Patients with cardiopulmonary edema and acute respiratory failure should be treated with continuous positive airway pressure (CPAP) and oxygen in addition to necessary cardiological interventions. This should be done already prehospital and in the emergency department.In case of other forms of acute hypoxaemic respiratory failure with only mild or moderately disturbed gas exchange (PaO2/FiO2 > 150 mmHg) there is no significant advantage or disadvantage compared to high flow nasal oxygen (HFNO). In severe forms of ARDS NIV is associated with high rates of treatment failure and mortality, especially in cases with NIV-failure and delayed intubation.NIV should be used for preoxygenation before intubation. In patients at risk, NIV is recommended to reduce extubation failure. In the weaning process from invasive ventilation NIV essentially reduces the risk of reintubation in hypercapnic patients. NIV is regarded useful within palliative care for reduction of dyspnea and improving quality of life, but here in concurrence to HFNO, which is regarded as more comfortable. Meanwhile NIV is also recommended in prehospital setting, especially in hypercapnic respiratory failure and pulmonary edema.With appropriate monitoring in an intensive care unit NIV can also be successfully applied in pediatric patients with acute respiratory insufficiency.

Abstract
Postoperative management after major and minor thoracic surgeries is crucial for patient recovery and can be challenging. Major thoracic surgeries, such as extensive pulmonary resections, especially in patients with poor health status, may require intensive surveillance, particularly during the first 24-72 h after surgery. Moreover, thanks to the demographic development and medical progress in perioperative medicine, more patients with comorbidities undergoing thoracic procedures require proper management in the postoperative period to improve prognosis and decrease hospital stay. Here, we summarize the main thoracic postoperative complications in order to clarify how to prevent them through a series of standardized procedures.

Abstract
The risk of pulmonary complications is high after major abdominal surgery but may be reduced by prophylactic postoperative noninvasive ventilation using continuous positive airway pressure (CPAP). This study compared the effects of intermittent mask CPAP (ICPAP) and continuous helmet CPAP (HCPAP) on oxygenation and the risk of pulmonary complications following major abdominal surgery. Patients undergoing open abdominal aortic aneurysm repair or pancreaticoduodenectomy were randomized (1:1) to either postoperative ICPAP or HCPAP. Oxygenation was evaluated as the partial pressure of oxygen in arterial blood fraction of inspired oxygen ratio (PaO2/FIO2) at 6 h, 12 h, and 18 h postoperatively. Pulmonary complications were defined as X-ray verified pneumonia/atelectasis, clinical signs of pneumonia, or supplementary oxygen beyond postoperative day 3. Patient-reported comfort during CPAP treatment was also evaluated. In total, 96 patients (ICPAP, n = 48; HCPAP, n = 48) were included, and the type of surgical procedure were evenly distributed between the groups. Oxygenation did not differ between the groups by 6 h, 12 h, or 18 h postoperatively (p = 0.1, 0.08, and 0.67, respectively). Nor was there any difference in X-ray verified pneumonia/atelectasis (p = 0.40) or supplementary oxygen beyond postoperative day 3 (p = 0.53). Clinical signs of pneumonia tended to be more frequent in the ICPAP group (p = 0.06), yet the difference was not statistically significant. Comfort scores were similar in both groups (p = 0.43), although a sensation of claustrophobia during treatment was only experienced in the HCPAP group (11% vs. 0%, p = 0.03). Compared with ICPAP, using HCPAP was associated with similar oxygenation (i.e., PaO2/FIO2 ratio) and a similar risk of pulmonary complications. However, HCPAP treatment was associated with a higher sensation of claustrophobia.

Abstract
Abstract
Background
Incentive spirometry (IS) is mostly used postoperatively to avoid pulmonary complications, but its effect on COPD patients and its effect on diaphragmatic functions are still not fully studied. The current study aimed to evaluate the value of IS on arterial blood gases, mMRC dyspnea scale, spirometry, and diaphragmatic functions by ultrasound in patients hospitalized for COPD exacerbation.
Methods and patients
Forty patients (37 males, 3 females) were admitted for COPD exacerbations and divided randomly into 2 groups: Group1 (G1) =20 patients (mean age 60.7±5.99) used incentive spirometry (IS) for 2 months with medical treatment. Group 2 as a control group (G2) = 20 patients (mean age 60.3±6.44) were given medical treatment only. ABG, spirometry, mMRC dyspnea scale, and diaphragmatic ultrasound functions were assessed on admission and after 2 months of treatment in the groups.
Results
There were statistically significant differences between G1 and G2 after 2 months regarding PaCO2, FEV1/FVC (p=0.001 and 0.042, respectively), and Lt diaphragmatic excursion and diaphragm thickness ratio. There was a statistically significant increase in results of PaO2, PaCO2, FEV1/FVC, PEFR, and all diaphragmatic findings in group I before and after 2 months of IS but no difference in FVC and mMRC dyspnea scale.
Conclusion
Incentive spirometry in COPD patients seems to improve ABG, and spirometry functions together with improving diaphragmatic functions.

Abstract
Abstract
Background
CPAP is characterized by the application of a constant and continuous positive pressure into the patient’s airway. By delivering a constant pressure during both inspiration and expiration, CPAP increases functional residual capacity and opens collapsed or under ventilated alveoli, thus decreasing right to left intrapulmonary shunt and improving oxygenation in obese individuals.
Main body of abstract
Obesity is characterized by several alterations in the mechanics of the respiratory system that tend to further exaggerate impairment of gas exchange rendering these patients prone to perioperative complications, such as hypoxemia, hypercapnia, and atelectasis. Interestingly, CPAP has been advocated as an efficacious modality for prevention and treatment of postoperative atelectasis considered to be the most common postoperative respiratory complication. In OSA, the CPAP device works to splint the airway open and prevent the collapse of the upper airway that is the cardinal event of OSA leading improvement of sleep, quality of life and the reduction of the risks of the cardiovascular and neurocognitive side effects associated with the disease. Besides such a beneficial effect, there are other physiological benefits to CPAP: greater end-expiratory lung volume and consequent increase in oxygen stores, increased tracheal traction to improve upper airway patency and decrease in cardiac after load.
Conclusion
Due to various physiological benefits on the respiratory system CPAP therapy is crucial for the prevention postoperative complications particularly related to obesity and the cornerstone for the treatment of moderate to severe obstructive sleep apnea.

Abstract
OBJECTIVES Postoperative pulmonary complications (PPCs) are a leading cause of morbidity and mortality following upper abdominal surgery. Applying either noninvasive ventilation (NIV) or continuous positive airway pressure (CPAP) in the early postoperative period is suggested to prevent PPC. We aimed to assess whether postoperative NIV or CPAP or both prevent PPCs compared with standard care in adults undergoing upper abdominal surgery, including in those identified at higher PPC risk. Additionally, the different interventions used were evaluated to assess whether there is a superior approach. DATA SOURCES We searched PubMed, Embase' CINAHL, CENTRAL, and Scopus from inception to May 17, 2021. STUDY SELECTION We performed a systematic search of the literature for randomized controlled trials evaluating prophylactic NIV and/or CPAP in the postoperative period. DATA EXTRACTION Two authors independently performed study selection and data extraction. Individual study risk of bias was assessed using the PEDro scale, and certainty in outcomes was assessed using the Grading of Recommendations Assessment, Development, and Evaluation framework. DATA SYNTHESIS We included 17 studies enrolling 6,108 patients. No significant benefit was demonstrated for postoperative NIV/CPAP to reduce PPC (risk ratio [RR], 0.89; 95% CI, 0.78-1.01; very low certainty), including in adults identified at higher PPC risk (RR, 0.91; 95% CI, 0.77-1.07; very low certainty). No intervention approach was identified as superior, and no significant benefit was demonstrated when comparing: 1) CPAP (RR, 0.90; 95% CI, 0.79-1.04; very low certainty), 2) NIV (RR, 0.68; 95% CI, 0.41-1.13; very low certainty), 3) continuous NIV/CPAP (RR, 0.90; 95% CI, 0.77-1.05; very low certainty), or 4) intermittent NIV/CPAP (RR, 0.66; 95% CI, 0.39-1.10; very low certainty) to standard care. CONCLUSIONS These findings suggest routine provision of either prophylactic NIV or CPAP following upper abdominal surgery may not be effective to reduce PPCs' including in those identified at higher risk.

Abstract
BACKGROUND Currently, consensus on the effectiveness of incentive spirometry (IS) following cardiac, thoracic, and upper abdominal surgery has been based on randomized controlled trials (RCTs) and systematic reviews of lower methodological quality. To improve the quality of the research and to account for the effects of IS following thoracic surgery, in addition to cardiac and upper abdominal surgery, we performed a meta-analysis with thorough application of the Grading of Recommendations Assessment, Development and Evaluation scoring system and extensive reference to the Cochrane Handbook for Systematic Reviews of Interventions. OBJECTIVE The objective of this study was to determine, with rigorous methodology, whether IS for adult patients (18 years of age or older) undergoing cardiac, thoracic, or upper abdominal surgery significantly reduces30-day post-operative pulmonary complications (PPCs), 30-day mortality, and length of hospital stay (LHS) when compared to other rehabilitation strategies. METHODS The literature was searched using Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE, CINAHL, and Web of Science for RCTs between the databases' inception and March 2019. A random-effect model was selected to calculate risk ratios (RRs) with 95% confidence intervals (CIs). RESULTS Thirty-one RCTs involving 3,776 adults undergoing cardiac, thoracic, or upper abdominal surgery were included. By comparing the use of IS to other chest rehabilitation strategies, we found that IS alone did not significantly reduce 30-day PPCs (RR = 1.00, 95% CI: 0.88-1.13) or 30-day mortality (RR = 0.73, 95% CI: 0.42-1.25). Likewise, there was no difference in LHS (mean difference = -0.17,95% CI: -0.65 to 0.30) between IS and the other rehabilitation strategies. None of the included trials significantly impacted the sensitivity analysis and publication bias was not detected. CONCLUSIONS This meta-analysis showed that IS alone likely results in little to no reduction in the number of adult patients with PPCs, in mortality, or in the LHS, following cardiac, thoracic, and upper abdominal surgery.

Abstract
OBJECTIVES To establish an optimized airway management process to improve preoperative lung dysfunction in obstructive sleep apnea (OSA). METHODS The study included 483 children (319 males and 164 females; 6y to14y years) with OSA who underwent an adenotonsillectomy from November 2017 to December 2018. Children with OSA and who had abnormal airway function were identified by lung function test, and the risk factors for abnormal lung function were assessed. Next, the children received individualized atomization intervention based on the severity of their abnormal lung function, and the improvement in lung function was evaluated. RESULTS Lung function tests revealed that 45 patients had obstructive ventilation dysfunction, and histories of chronic cough or asthma were identified as risk factors for perioperative abnormal lung function. The FEV1% pre exceeded 80% after 2 days of atomization intervention in 27 of 28 mild cases, 4 of 13 moderate cases, but in none of the 4 moderate-severe cases. After 4 days of atomization intervention, the FEV1%pre of the remaining 14 patients in the three groups all increased up to 80%. Other indicators of lung function (e.g., FEV1/FVC% pre, MEF50% pre, MEF25% pre, and MMEF% pre) were also greatly improved following the improvement of FEV1% pre. No perioperative airway complications occurred. CONCLUSIONS Prior to performing surgery on children with OSA and who have risk factors associated with abnormal lung function, it is potentially beneficial to establish an optimized airway management process to improve lung function before adenotonsillectomy.

Abstract
BACKGROUND General anesthesia-induced atelectasis is common, and persistent postoperative atelectasis is associated with pulmonary complications. We aimed to evaluate the preventive effects of a high-flow nasal cannula (HFNC) on postoperative atelectasis and respiratory complications in infants and small children. METHODS In this prospective randomized controlled trial, children (≤2 years) receiving general anesthesia (>2 hours) were randomized into the control and HFNC groups. At the end of the surgery, the first lung ultrasound evaluation was performed in both groups. In the postanesthetic care unit (PACU), the control group received conventional oxygen therapy, while the HFNC group received oxygen via HFNC, with a flow rate of 2 L kg-1 min-1. Before discharge to the ward, a second lung ultrasound examination was performed. The primary outcome was the lung ultrasound score at PACU discharge. The secondary outcomes included the lung ultrasound score at the end of surgery, the incidence of significant atelectasis at PACU discharge, and other postoperative outcomes. RESULTS Lung ultrasound score and the incidence of atelectasis at the end of surgery did not differ significantly between the control (n = 38) and HFNC (n = 40) groups. After staying in the PACU, both groups showed a reduced lung ultrasound score and atelectasis incidence. However, the HFNC group had a significantly lower consolidation score than the control group (0; interquartile range [IQR] = 0-1 vs 3; IQR = 2-4; P< .001). Additionally, none of the patients had significant atelectasis in the HFNC group, compared to 6 patients in the control group (0% vs 15.8%; odds ratio [OR] = 0.444; 95% confidence interval for OR, 0.343-0.575; P = .011). Incidence of desaturation (oxygen saturation [Spo2] ≤ 95%), postoperative complications, and the length of hospital stay did not differ between the groups. CONCLUSIONS Preventive use of HFNC after surgery improves the lung ultrasound score and reduces postoperative atelectasis compared to conventional oxygen therapy in infants and small children.

Abstract
Cardiorespiratory (CR) signals are crucial vital signs for fitness condition tracking, medical diagnosis, and athlete performance evaluation. Monitoring such signals in real-life settings is among the most widespread applications of wearable computing. We investigate how miniaturized barometers can be used to perform accurate spirometry in a wearable system that is built on off-the-shelf training masks often used by athletes as a training aid. We perform an evaluation where differential barometric pressure sensors are compared concurrently with a digital spirometer, during an experimental setting of clinical forced vital capacity (FVC) test procedures with 20 participants. The relationship between the two instruments is derived by mathematical modeling first, then by various regression methods from experiment data. The results show that the error of FVC vital values between the two instruments can be as low as 2∼3%. Beyond clinical tests, the method can also measure continuous tidal breathing air volumes with a 1∼3% error margin. Overall, we conclude that barometers with millimeter footprints embedded in face mask apparel can perform similarly to a digital spirometer to monitor breathing airflow and volume in pulmonary function tests.

Abstract
Setting: The coronavirus disease 2019 pandemic has raised fear throughout the nation. Current news and social media predictions of ventilator, medication, and personnel shortages are rampant. Patients: Patients with coronavirus disease 2019 are presenting with early respiratory distress and hypoxemia, but not hypercapnia. Interventions: Patients who maintain adequate alveolar ventilation, normocapnia, and adequate oxygenation may avoid the need for tracheal intubation. Facemask continuous positive airway pressure has been used to treat patients with respiratory distress for decades, including those with severe acute respiratory syndrome. Of importance, protocols were successful in protecting caregivers from contracting the virus, obviating the need for tracheal intubation just to limit the spread of potentially infectious particles. Conclusions: During a pandemic, with limited resources, we should provide the safest and most effective care, while protecting caregivers. Continuous positive airway pressure titrated to an effective level and applied early with a facemask may spare ventilator usage. Allowing spontaneous ventilation will decrease the need for sedative and paralytic drugs and may decrease the need for highly skilled nurses and respiratory therapists. These goals can be accomplished with devices that are readily available and easier to obtain than mechanical ventilators, which then can be reserved for the sickest patients.

Abstract
Background Cardiac surgery often leads to pulmonary complications. Non-invasive ventilation (NIV) is a mechanical ventilation modality that may help to prevent the pulmonary complications, and the role of the prophylactic use of NIV in patients after cardiac surgery remains controversial. Methods We searched PubMed, Embase, Web of Science and Cochrane Central for randomized controlled trials comparing the use of NIV (continues positive airway pressure or bi-level positive airway pressure) with standard treatment in post-cardiac surgery subjects without language restriction. Two investigators screened the eligible studies up to July, 2019. Meta-analysis using random effect model or fixed effect model was conducted for pulmonary complications, mortality, rate of reintubation and cardiac complications, and mean difference (MD) or standard mean difference for length of hospital stay and length of ICU stay. Results We included nine randomized controlled trails with 830 subjects. The use of NIV failed to reduce the risk of pulmonary complications, including atelectasis [risk rate (RR) 0.60; 95% confidence interval (CI): 0.28 to 1.28, P=0.19] and pneumonia (RR 0.27; 95% CI: 0.05 to 1.64, P=0.16). However, it has shortened the length of ICU stay (MD -1.00 h, 95% CI: -1.38 to -0.63, P<0.00001) and the length of hospital stay (MD -1.00 d, 95% CI: -1.12 to -0.87, P<0.00001). NIV also failed to reduce the rate of reintubation (RR 0.68; 95% CI: 0.21 to 2.26, P=0.53) or the risk of cardiac complications (RR 0.81; 95% CI: 0.59 to 1.13, P=0.22). Conclusions The prophylactic use of NIV immediately in post-cardiac subjects who underwent cardiac surgery might be able to shorten the length of hospital stay and the length of ICU stay, but it has no significant effect on pulmonary complications, rate of reintubation or cardiac complications.

Abstract
Perioperative lung injury is a major source of postoperative morbidity, excess healthcare use, and avoidable mortality. Many potential inciting factors can lead to this condition, including intraoperative ventilator induced lung injury. Questions exist as to whether protective ventilation strategies used in the intensive care unit for patients with acute respiratory distress syndrome are equally beneficial for surgical patients, most of whom do not present with any pre-existing lung pathology. Studied both individually and in combination as a package of intraoperative lung protective ventilation, the use of low tidal volumes, moderate positive end expiratory pressure, and recruitment maneuvers have been shown to improve oxygenation and pulmonary physiology and to reduce postoperative pulmonary complications in at risk patient groups. Further work is needed to define the potential contributions of alternative ventilator strategies, limiting excessive intraoperative oxygen supplementation, use of non-invasive techniques in the postoperative period, and personalized mechanical ventilation. Although the weight of evidence strongly suggests a role for lung protective ventilation in moderate risk patient groups, definitive evidence of its benefit for the general surgical population does not exist. However, given the shift in understanding of what is needed for adequate oxygenation and ventilation under anesthesia, the largely historical arguments against the use of intraoperative lung protective ventilation may soon be outdated, on the basis of its expanding track record of safety and efficacy in multiple settings.

Abstract
Introduction: Impairment of global and regional pulmonary ventilations is a well-known consequence of general anesthesia. Positive expiratory pressure (PEP) or incentive spirometry (IS) is commonly prescribed, albeit their efficacy is poorly demonstrated. The aim of this study was to assess the effects of PEP and IS on lung ventilation and recruitment in patients after surgery involving anesthesia using electrical impedance tomography (EIT). Method: Ten male subjects (age = 61.2 ± 16.3 years; BMI = 25.3 ± 3.8 kg/m2), free of pulmonary disease before being anesthetized, were recruited. Two series of manoeuvers (PEP and volume-oriented IS) were randomly performed with quiet breathing interposed between these phases. Pulmonary ventilation (ΔEELVVT (i - e)) and recruitment (ΔEELI) were evaluated continuously in a semi-seated position during all phases by EIT. Comparisons between rest and treatment were performed by Wilcoxon signed rank test. Rest phases were compared by a mixed ANOVA. Bonferroni method was used for post-hoc comparisons. Results: ΔEELVVT (i - e) and ΔEELI were significantly increased by both techniques (+422% [p < 0.001]; +138% [p = 0.040] and +296% [p < 0.001]; +638% [p < 0.001] for PEP and IS, respectively). No difference was observed between both manoeuvers neither on ventilation nor on recruitment. This positive effect disappeared during the quiet breathing phases. Conclusion: IS and PEP improved ventilation and recruitment instantaneously without remnant effect after stopping the exercise.

Abstract
STUDY OBJECTIVE Volume controlled ventilation with low PEEP is used in neuro-anesthesia to provide constant PaCO2 levels and prevent raised intracranial pressure. Therefore, neurosurgery patients prone to atelectasis formation, however, we could not find any study that evaluates prevention of postoperative pulmonary complications in neurosurgery. DESIGN A prospective, randomized controlled study. SETTING Intensive care unit in a university hospital in Istanbul. PATIENTS Seventy-nine ASAI-II patients aged between 18 and 70years scheduled for elective supratentorial craniotomy were included in the study. INTERVENTIONS Patients randomized into 3 groups after surgery. The Group IS (n=20) was treated with incentive spirometry 5 times in 1min and 5min per hour, the Group CPAP (n=20) with continuous positive airway pressure 10 cmH2O pressure and 0.4 FiO2 via an oronasal mask 5min per hour, and the Group Control (n=20) 4L·min-1O2 via mask; all during the first 6h postoperatively. Respiratory functions tests and arterial blood gases analysis were performed before the induction of anesthesia (Baseline), 30min, 6h, 24h postoperatively. MAIN RESULTS The IS and CPAP applications have similar effects with respect to FVC values. The postoperative 30min FEV1 values were statistically significantly reduced compared to the Baseline in all groups (p<0.0001). FEV1 values were statistically significantly increased at the postoperative 24h compared to the postoperative 30min in the Groups IS and CPAP (p<0.0001). This increase, however, was not observed in the Group Control, and the postoperative 24h FEV1 values were statistically significantly lower in the Group Control compared to the Group IS (p=0.015). CONCLUSION Although this study is underpowered to detect differences in FEV1 values, the postoperative 24h FEV1 values were significantly higher in the IS group than the Control group and this difference was not observed between the CPAP and Control groups. It might be evaluate a favorable effect of IS in neurosurgery patients. But larger studies are needed to make a certain conclusion.

Abstract
BACKGROUND Each year, more than four million abdominal surgeries are performed in the US and over 250,000 in England. Acute respiratory failure, a common complication that can affect 30% to 50% of people after upper abdominal surgery, can lead to significant morbidity and mortality. Noninvasive ventilation has been associated with lower rates of tracheal intubation in adults with acute respiratory failure, thus reducing the incidence of complications and mortality. This review compared the effectiveness and safety of noninvasive positive pressure ventilation (NPPV) versus standard oxygen therapy in the treatment of acute respiratory failure after upper abdominal surgery. OBJECTIVES To assess the effectiveness and safety of noninvasive positive pressure ventilation (NPPV), that is, continuous positive airway pressure (CPAP) or bilevel NPPV, in reducing mortality and the rate of tracheal intubation in adults with acute respiratory failure after upper abdominal surgery, compared to standard therapy (oxygen therapy), and to assess changes in arterial blood gas levels, hospital and intensive care unit (ICU) length of stay, gastric insufflation, and anastomotic leakage. SEARCH METHODS The date of the last search was 12 May 2015. We searched the following databases: the Cochrane Handbook for Systematic Reviews of Interventions (CENTRAL) (2015, Issue 5), MEDLINE (Ovid SP, 1966 to May 2015), EMBASE (Ovid SP, 1974 to May 2015); the physiotherapy evidence database (PEDro) (1999 to May 2015); the Cumulative Index to Nursing and Allied Health Literature (CINAHL, EBSCOhost, 1982 to May 2015), and LILACS (BIREME, 1986 to May 2015). We reviewed reference lists of included studies and contacted experts. We also searched grey literature sources. We checked databases of ongoing trials such as www.controlled-trials.com/ and www.trialscentral.org/. We did not apply language restrictions. SELECTION CRITERIA We selected randomized or quasi-randomized controlled trials involving adults with acute respiratory failure after upper abdominal surgery who were treated with CPAP or bilevel NPPV with, or without, drug therapy as standard medical care, compared to adults treated with oxygen therapy with, or without, standard medical care. DATA COLLECTION AND ANALYSIS Two authors independently selected and abstracted data from eligible studies using a standardized form. We evaluated study quality by assessing allocation concealment; random sequence generation; incomplete outcome data; blinding of participants, personnel, and outcome assessors; selective reporting; and adherence to the intention-to-treat (ITT) principle. MAIN RESULTS We included two trials involving 269 participants. The participants were mostly men (67%); the mean age was 65 years. The trials were conducted in China and Italy (one was a multicentre trial). Both trials included adults with acute respiratory failure after upper abdominal surgery. We judged both trials at high risk of bias. Compared to oxygen therapy, CPAP or bilevel NPPV may reduce the rate of tracheal intubation (risk ratio (RR) 0.25; 95% confidence interval (CI) 0.08 to 0.83; low quality evidence) with a number needed to treat for an additional beneficial outcome of 11. There was very low quality evidence that the intervention may also reduce ICU length of stay (mean difference (MD) -1.84 days; 95% CI -3.53 to -0.15). We found no differences for mortality (low quality evidence) and hospital length of stay. There was insufficient evidence to be certain that CPAP or NPPV had an effect on anastomotic leakage, pneumonia-related complications, and sepsis or infections. Findings from one trial of 60 participants suggested that bilevel NPPV, compared to oxygen therapy, may improve blood gas levels and blood pH one hour after the intervention (partial pressure of arterial oxygen (PaO2): MD 22.5 mm Hg; 95% CI 17.19 to 27.81; pH: MD 0.06; 95% CI 0.01 to 0.11; partial pressure of arterial carbon dioxide (PCO2) levels (MD -9.8 mm Hg; 95% CI -14.07 to -5.53). The trials included in this systematic review did not present data on the following outcomes that we intended to assess: gastric insufflation, fistulae, pneumothorax, bleeding, skin breakdown, eye irritation, sinus congestion, oronasal drying, and patient-ventilator asynchrony. AUTHORS' CONCLUSIONS The findings of this review indicate that CPAP or bilevel NPPV is an effective and safe intervention for the treatment of adults with acute respiratory failure after upper abdominal surgery. However, based on the Grading of Recommendations Assessment, Development and Evaluation (GRADE) methodology, the quality of the evidence was low or very low. More good quality studies are needed to confirm these findings.

Abstract
Non-invasive ventilation (NIV) is a method of ventilatory support that is increasing in importance day by day in the management of postoperative respiratory failure. Its role in the prevention and treatment of atelectasis is particularly important in the in the period after thoracic and abdominal surgeries. Similarly, in the transplanted patient, NIV can shorten the time of invasive mechanical ventilation, reducing the risk of infectious complications in these high-risk patients. It has been performed A systematic review of the literature has been performed, including examining the technical, clinical experiences and recommendations concerning the application of NIV in the postoperative period.

Abstract
OBJECTIVE The aim of our study is to investigate the effect of two different methods of continuous positive airway pressure (CPAP) and bilevel positive airway pressure (BIPAP) and oxygen support under spontaneous ventilation on respiration mechanics, gas exchange, dry mouth and face mask lesion during an early postoperative period in patients undergoing upper abdominal surgery. METHODS Eighty patients undergoing elective abdominal surgery with laparotomy, between the age of 25 and 75 years and American Society of Anesthesiologists Physical Status score (ASA) II-III with chronic obstructive pulmonary disease (COPD) diagnosis were included to the study. Subjects were randomly allocated in to four groups. During the first postoperative hour, the first group received BIPAP, second group received high-flow CPAP, third group received low-flow CPAP and fourth group received deep breathing exercises, respiratory physiotherapy and O2 therapy. Preoperative, postoperative before and after treatment PaO2, PaCO2, SpO2, tidal volume (TV), respiratory rate (RR) levels were recorded. Subjects with dry mouth or face mask lesion were recorded. RESULTS In all groups, PaO2 and TV measurements were higher at the postoperative first hour than the postoperative zero hour. We found that low-flow CPAP increased PaO2 and SpO2 values more, and TV levels were higher in the postoperative period than the preoperative period. PaCO2 levels were elevated at the zero hour postoperatively and at the end of the first hour; they decreased approximately to preoperative values, except in the fourth group. CONCLUSION Administration of prophylactic respiratory support can prevent the deterioration of pulmonary functions and hypoxia in patients with COPD undergoing upper abdominal surgery. In addition, we found that low-flow CPAP had better effects on PaO2, SpO2, TV compared to other techniques.

Abstract
BACKGROUND Major abdominal surgery can be associated with a number of serious complications that may impair patient recovery. In particular, postoperative pulmonary complications (PPCs), including respiratory complications such as atelectasis and pneumonia, are a major contributor to postoperative morbidity and may even contribute to increased mortality. Continuous positive airway pressure (CPAP) is a type of therapy that uses a high-pressure gas source to deliver constant positive pressure to the airways throughout both inspiration and expiration. This approach is expected to prevent some pulmonary complications, thus reducing mortality. OBJECTIVES To determine whether any difference can be found in the rate of mortality and adverse events following major abdominal surgery in patients treated postoperatively with CPAP versus standard care, which may include traditional oxygen delivery systems, physiotherapy and incentive spirometry. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL) 2013, Issue 9; Ovid MEDLINE (1966 to 15 September 2013); EMBASE (1988 to 15 September 2013); Web of Science (to September 2013) and the Cumulative Index to Nursing and Allied Health Literature (CINAHL) (to September 2013). SELECTION CRITERIA We included all randomized controlled trials (RCTs) in which CPAP was compared with standard care for prevention of postoperative mortality and adverse events following major abdominal surgery. We included all adults (adults as defined by individual studies) of both sexes. The intervention of CPAP was applied during the postoperative period. We excluded studies in which participants had received PEEP during surgery. DATA COLLECTION AND ANALYSIS Two review authors independently selected studies that met the selection criteria from all studies identified by the search strategy. Two review authors extracted the data and assessed risk of bias separately, using a data extraction form. Data entry into RevMan was performed by one review author and was checked by another for accuracy. We performed a limited meta-analysis and constructed a summary of findings table. MAIN RESULTS We selected 10 studies for inclusion in the review from 5236 studies identified in the search. These 10 studies included a total of 709 participants. Risk of bias for the included studies was assessed as high in six studies and as unclear in four studies.Two RCTs reported all-cause mortality. Among 413 participants, there was no clear evidence of a difference in mortality between CPAP and control groups, and considerable heterogeneity between trials was noted (risk ratio (RR) 1.28, 95% confidence interval (CI) 0.35 to 4.66; I(2) = 75%).Six studies reported demonstrable atelectasis in the study population. A reduction in atelectasis was observed in the CPAP group, although heterogeneity between studies was substantial (RR 0.62, 95% CI 0.45 to 0.86; I(2) = 61%). Pneumonia was reported in five studies, including 563 participants; CPAP reduced the rate of pneumonia, and no important heterogeneity was noted (RR 0.43, 95% CI 0.21 to 0.84; I(2) = 0%). The number of participants identified as having serious hypoxia was reported in two studies, with no clear difference between CPAP and control groups, given imprecise results and substantial heterogeneity between trials (RR 0.48, 95% CI 0.22 to 1.02; I(2) = 67%). A reduced rate of reintubation was reported in the CPAP group compared with the control group in two studies, and no important heterogeneity was identified (RR 0.14, 95% CI 0.03 to 0.58; I(2) = 0%). Admission into the intensive care unit (ICU) for invasive ventilation and supportive care was reduced in the CPAP group, but this finding did not reach statistical significance (RR 0.45, 95% CI 0.18 to 1.14; I(2) = 0).Secondary outcomes such as length of hospital stay and adverse effects were only minimally reported.A summary of findings table was constructed using the GRADE (Grades of Recommendation, Assessment, Development and Evaluation) principle. The quality of evidence was determined to be very low. AUTHORS' CONCLUSIONS Very low-quality evidence from this review suggests that CPAP initiated during the postoperative period might reduce postoperative atelectasis, pneumonia and reintubation, but its effects on mortality, hypoxia or invasive ventilation are uncertain. Evidence is not sufficiently strong to confirm the benefits or harms of CPAP during the postoperative period in those undergoing major abdominal surgery. Most of the included studies did not report on adverse effects attributed to CPAP.New, high-quality research is much needed to evaluate the use of CPAP in preventing mortality and morbidity following major abdominal surgery. With increasing availability of CPAP to our surgical patients and its potential to improve outcomes (possibly in conjunction with intraoperative lung protective ventilation strategies), unanswered questions regarding its efficacy and safety need to be addressed. Any future study must report on the adverse effects of CPAP.

Abstract
BACKGROUND This is an update of a Cochrane Review first published in The Cochrane Library 2008, Issue 3.Upper abdominal surgical procedures are associated with a high risk of postoperative pulmonary complications. The risk and severity of postoperative pulmonary complications can be reduced by the judicious use of therapeutic manoeuvres that increase lung volume. Our objective was to assess the effect of incentive spirometry compared to no therapy or physiotherapy, including coughing and deep breathing, on all-cause postoperative pulmonary complications and mortality in adult patients admitted to hospital for upper abdominal surgery. OBJECTIVES Our primary objective was to assess the effect of incentive spirometry (IS), compared to no such therapy or other therapy, on postoperative pulmonary complications and mortality in adults undergoing upper abdominal surgery.Our secondary objectives were to evaluate the effects of IS, compared to no therapy or other therapy, on other postoperative complications, adverse events, and spirometric parameters. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2013, Issue 8), MEDLINE, EMBASE, and LILACS (from inception to August 2013). There were no language restrictions. The date of the most recent search was 12 August 2013. The original search was performed in June 2006. SELECTION CRITERIA We included randomized controlled trials (RCTs) of IS in adult patients admitted for any type of upper abdominal surgery, including patients undergoing laparoscopic procedures. DATA COLLECTION AND ANALYSIS Two authors independently assessed trial quality and extracted data. MAIN RESULTS We included 12 studies with a total of 1834 participants in this updated review. The methodological quality of the included studies was difficult to assess as it was poorly reported, so the predominant classification of bias was 'unclear'; the studies did not report on compliance with the prescribed therapy. We were able to include data from only 1160 patients in the meta-analysis. Four trials (152 patients) compared the effects of IS with no respiratory treatment. We found no statistically significant difference between the participants receiving IS and those who had no respiratory treatment for clinical complications (relative risk (RR) 0.59, 95% confidence interval (CI) 0.30 to 1.18). Two trials (194 patients) IS compared incentive spirometry with deep breathing exercises (DBE). We found no statistically significant differences between the participants receiving IS and those receiving DBE in the meta-analysis for respiratory failure (RR 0.67, 95% CI 0.04 to 10.50). Two trials (946 patients) compared IS with other chest physiotherapy. We found no statistically significant differences between the participants receiving IS compared to those receiving physiotherapy in the risk of developing a pulmonary condition or the type of complication. There was no evidence that IS is effective in the prevention of pulmonary complications. AUTHORS' CONCLUSIONS There is low quality evidence regarding the lack of effectiveness of incentive spirometry for prevention of postoperative pulmonary complications in patients after upper abdominal surgery. This review underlines the urgent need to conduct well-designed trials in this field. There is a case for large RCTs with high methodological rigour in order to define any benefit from the use of incentive spirometry regarding mortality.

Abstract
PURPOSE OF REVIEW Pulmonary complications ranging from atelectasis to acute respiratory failure are common causes of poor perioperative outcomes. As the surgical population becomes increasingly at risk for pulmonary dysfunction due to increasing age and weight, development of an approach toward respiratory compromise in these patients is becoming ever more important. Given the utility of noninvasive respiratory support (NRS) in acute respiratory failure, it is likewise likely to also be important in the perioperative period. RECENT FINDINGS NRS is evaluated from preoperative risk assessment to its use in prevention and treatment of acute respiratory failure. Data supporting intraoperative use of NRS including preinduction continuous positive airway pressure and postextubation NRS for high-risk individuals and surgeries are examined. Timing and duration of NRS is also addressed. Finally, NRS is proposed for treatment for postoperative acute respiratory failure as an alternative to invasive rescue maneuvers. SUMMARY Noninvasive respiratory support should be considered an important adjunct in perioperative pulmonary care. Usage should be individually tailored in regard to timing and application modality specific to patient and surgical circumstances. More studies are needed, however, to determine the relationship demonstrated between short-term improvements in lung function and long-term outcomes.

Abstract
Noninvasive ventilation (NIV) refers to ventilation delivered through a noninvasive interface (a nasal or face mask) rather than an invasive interface (an endotracheal tube or tracheostomy). The role of NIV in preventing reintubation after abdominal surgery in pediatric patients is uncertain. Therefore, we evaluated the role of NIV for this purpose in pediatric patients after liver transplantation. We successfully started using NIV for respiratory complications (RCs) in pediatric patients undergoing liver transplantation in 1999. For this report, we screened all medical records of patients under the age of 12 years who underwent liver transplantation between 2001 and 2009, and we retrieved data for cases at high risk of extubation failure. We retrospectively compared the clinical outcomes of patients who received NIV during their intensive care unit (ICU) stay and patients who did not. Data for 94 cases (92 patients) were included in this analysis. NIV was used in 47 patients during their ICU stay. The rate of reintubation for RCs was significantly lower in NIV patients versus non-NIV patients [3/47 (6.4%) versus 11/47 (23.4%), P = 0.02]. Furthermore, the discharge rate from the ICU was significantly better for NIV patients versus non-NIV patients. The use of NIV after extubation prevented the worsening of atelectasis and stabilized respiratory conditions in this cohort. No major changes in operative procedures or other treatments during the examined period were found. In conclusion, NIV is acceptable and promising for the respiratory management of pediatric patients undergoing liver transplantation. Its use may stabilize respiratory conditions and decrease the need for reintubation in pediatric liver transplant patients, and it may also facilitate an early ICU discharge.

[EzPAP® therapy of postoperative hypoxemia in the recovery room : experiences with the new compact system of end-expiratory positive airway pressure]. Anaesthesist 2012; 61:867-74. [PMID: 23011043 DOI: 10.1007/s00101-012-2083-4] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/02/2012] [Revised: 08/07/2012] [Accepted: 08/22/2012] [Indexed: 10/27/2022]
Abstract
BACKGROUND Postoperative hypoxemia is a common complication in the anesthesia recovery room (ARR), which is predominantly based on the development of atelectasis, excessive intraoperative fluid shift and insufficient ventilation. The goal of this prospective observational study was to compare the effect of standard oxygen administration via a face mask with oxygen administration using the EzPAP® system, a device which additionally provides a positive end-expiratory pressure (PEEP). METHODS This study included 210 patients with postoperative hypoxemia (S(p)O(2) < 93%) subdivided into the control group (105 patients) and the EzPAP group (105 patients). Postoperative residual paralysis was excluded using relaxometry and a train of four (TOF) ratio of 0.9 was assumed to ensure sufficient recovery of respiratory function from neuromuscular blockade. Patients who received a reversal of neuromuscular blockade were excluded. In cases of hypoxemia (S(p)O(2) < 93%) control patients were treated with oxygen (6 l/min) using a face mask, whereas the EzPAP group received oxygen using the EzPAP® system. In order to adjust the PEEP in the EzPAP group, the O(2) flow was verified and measured by a manometer. After 1 h of oxygen therapy, the oxygen supply was stopped. In cases of reoccurring hypoxemia (S(p)O(2) < 93%, persistence > 5 min), the oxygen therapy was restarted in both groups via a facemask. Both groups were compared using repeat measurement analysis of variance (ANOVA), the unpaired t-test, the Mann-Whitney U-test, Fisher's exact test and the χ(2)-test. The correlation of O(2) flow and PEEP was evaluated by regression analysis and p < 0.05 was considered to be statistically significant. Apart from this a subgroup analysis was performed depending on body-mass index (BMI), American Society of Anesthesiologists (ASA) classification, intraoperative airway management, the use of neuromuscular blocking agents and co-existing disorders, e.g. chronic obstructive lung disease (COLD), obesity and chronic heart failure. RESULTS All patients were equally distributed between both groups with respect to demographic data, ASA classification, BMI, co-existing disorders and surgical procedures. The S(p)O(2) values did not differ between the EzPAP patients and the control group, except for 0.5 min after initiation of oxygen therapy: EzPAP group 96 ± 3.7% (mean ± standard deviation) versus the control group 93.8 ± 4.4% (p < 0.001). However, restarting oxygen therapy was less common in the EzPAP group (EzPAP group 25 versus control group 41, p = 0.03), as well as the occurrence of postoperative complications (EzPAP group 13 versus control group 25, p = 0.02), e.g. nosocomial pneumonia (0 versus 4) and wound infections (2 versus 3). Furthermore, patients with obesity and pulmonary disorders, such as COLD had a benefit from oxygen administration using the EzPAP device and showed higher postoperative than preoperative S(p)O(2) values. In contrast, the subgroup analysis of patients with heart failure did not reveal any differences between both groups and both groups did not differ in terms of time spent in the recovery room (EzPAP group 113 min versus control group 174.8 min, p = 0.2). CONCLUSIONS In this observational study oxygen supply using the EzPAP® system appeared to be at least equally as effective in the therapy of postoperative hypoxemia compared to standard oxygen supply using a face mask. In patients with a high risk of postoperative hypoxemia, such as patients with obesity and/or pulmonary disorders, oxygen administration using the EzPAP® system possibly improves pulmonary oxygenation more effectively and is longer lasting compared to standard oxygen supply via a face mask. Hence, the EzPAP® system represents a well-tolerated, effective, cost-effective and easily operated tool to improve postoperative oxygenation. In order to investigate the possibilities of this promising tool more intensively, randomized clinical trials are warranted.

Abstract
OBJECTIVE Prospective randomized controlled study was conducted to explore the effects and safety of prophylactic use of noninvasive positive pressure ventilation (NPPV) in post-thoracic surgery (PTS) patients, especially on the lung re-expansion, lung function change and postoperative pulmonary complications (PPCs). METHODS Fifty PTS patients met the inclusion criterion were enrolled in the study. All subjects were randomly divided into conventional treatment (control) group and NPPV group. NPPV group received intermittent NPPV therapy in first three days of PTS. BiPAP ventilator was used with S/T mode in the study. The average IPAP was (13±3.2)cmH(2)O (ranged from 7 to 18 cmH(2)O) and EPAP was 4cmH(2)O. Total ventilation time was (13.5±4.9) hours (ranged from 6.5 to 23 hours). PPCs rate, lung re-expansion, the volume of residual cavity, lung function and tolerance to NPPV were assessed with chest roentgenography, CT scan, lung function testing and clinical evaluation before and one week after surgery. RESULTS 1. There was no significant difference of total PPCs rate during hospitalization between the two groups (5/23 in NPPV group vs 6/27 in control group, P= 0.967). Multiple factorial logistic regression analysis showed that COPD was a risk factor for PPCs (B=1.705, P=0.027). 2. Compared with control group, NPPV therapy reduced inadequate lung expansion rate (3/23 vs 13/27, P=0.008) and volume of residual cavity calculated with CT scan [(31.9±71.7)ml vs (63.6±78.3)ml, P=0.02]. However, there were no significant difference in the change of lung function parameters after operation between the two groups (all P>0.05). No significant adverse effects of NPPV were found in the present study. CONCLUSIONS In the current study of prophylactic application of NPPV in post-thoracic surgery patients, the use of NPPV resulted in improved lung re-expansion, but had no significant effects on post-operative pulmonary complications and lung functions.

Abstract
General anesthesia and surgery are associated with changes in the shape of the chest that result in atelectasis, a major factor in the development of postoperative respiratory failure. Postoperative noninvasive positive pressure ventilation (NIPPV) has been shown to improve oxygenation and ventilation for high-risk patients. NIPPV has been used as rescue therapy for patients developing acute respiratory distress postoperatively, and appears to be most frequently successful in patients whose problem is atelectasis or obesity. Failure to respond to NIPPV after 20 minutes is usually an indication of intubation, mechanical ventilation, and transfer to the intensive care unit.

Abstract
OBJECTIVES To describe noninvasive positive-pressure ventilation use in intensive care unit clinical practice, factors associated with NPPV failure and the associated prognosis. METHODS A prospective cohort study. RESULTS Medical disorders (59%) and elective surgery (21%) were the main causes for admission to the intensive care unit. The main indications for the initiation of noninvasive positive-pressure ventilation were the following: post-extubation, acute respiratory failure and use as an adjunctive technique to chest physiotherapy. The noninvasive positive-pressure ventilation failure group was older and had a higher Simplified Acute Physiology Score II score. The noninvasive positive-pressure ventilation failure rate was 35%. The main reasons for intubation were acute respiratory failure (55%) and a decreased level of consciousness (20%). The noninvasive positive-pressure ventilation failure group presented a shorter period of noninvasive positive-pressure ventilation use than the successful group [three (2-5) versus four (3-7) days]; they had lower levels of pH, HCO3 and base excess, and the FiO2 level was higher. These patients also presented lower PaO2:FiO2 ratios; on the last day of support, the inspiratory positive airway pressure and expiratory positive airway pressure were higher. The failure group also had a longer average duration of stay in the intensive care unit [17 (10-26) days vs. 8 (5-14) days], as well as a higher mortality rate (9 vs. 51%). There was an association between failure and mortality, which had an odds ratio (95% CI) of 10.6 (5.93 -19.07). The multiple logistic regression analysis using noninvasive positive pressure ventilation failure as a dependent variable found that treatment tended to fail in patients with a Simplified Acute Physiology Score II ≥ 34, an inspiratory positive airway pressure level ≥ 15 cmH2O and pH<7.40. CONCLUSION The indications for noninvasive positive-pressure ventilation were quite varied. The failure group had a longer intensive care unit stay and higher mortality. Simplified Acute Physiology Score II ≥ 34, pH<7.40 and higher inspiratory positive airway pressure levels were associated with failure.

Abstract
Postoperative pulmonary complications (atelectasis, pneumonia, pulmonary edema, acute respiratory failure) are common, particularly after abdominal and thoracic surgery, pneumonia and atelectasis being the most common. Postoperative pneumonia is associated with increased morbidity, length of hospital stay, and costs. Few institutions have pneumonia prevention programs for surgical patients, and these should be strongly considered. Acute respiratory failure is a life-threatening pulmonary complication that requires institution of mechanical ventilation and admission to the intensive care unit, and is associated with increased risk for ventilator-associated pneumonia. This article discusses epidemiology, risk factors, diagnosis, treatment, and prevention of these pulmonary complications in surgical patients.

Abstract
Pulmonary arteriovenous fistulas have congenital and hereditary etiology, and patients are at risk for life-threatening rupture requiring surgery. Wegener's granulomatosis can affect any organ system, although renal and pulmonary involvement is most common; men ages 40 to 50 are at increased risk. Lymphomatoid granulomatosis affects cardiopulmonary, neurologic, and myeloproliferative systems; may result from opportunistic infection, and frequently progresses to lymphoma; men age 50 to 60 are at increased risk. Spontaneous remission occurs in some cases; mortality is 60% to 90% at 5 years. Churg-Strauss syndrome is usually associated with long-standing asthma, with men and women affected equally, and can affect any organ system; major cause of death is cardiac related. Primary pulmonary hypertension is a diagnosis of exclusion; women are affected twice as likely as men; right-to-left shunt may occur in 30%, secondary to patent foramen ovale; hypoxia with resultant heart failure is typical cause of death. Cystic fibrosis is an autosomal recessive disease, eventually fatal, with increased risk for airway obstruction, fluctuating pulmonary function, and chronic hypoxia; risk for spontaneous pneumothorax is 20%. Bronchiolitis obliterans organizing pneumonia is a pulmonary obstructive disease that may be reversible and usually resolves spontaneously. Idiopathic pulmonary hemosiderosis is associated with autoimmune disorders; patients have recurrent hemorrhage, pulmonary fibrosis, restrictive lung disease, and pulmonary hypertension, with some cases of spontaneous remission. Chronic eosinophilic pneumonia may be preceded by adult-onset asthma; women are at increased risk; prognosis is good. Goodpasture's syndrome is a genetic autoimmune disorder involving the pulmonary and renal systems. Pulmonary alveolar proteinosis, a lipoprotein-rich accumulation in alveoli, has three forms: congenital, decreased alveolar macrophage activity, and idiopathic; some cases of spontaneous remission occur. Sarcoidosis may affect any organ system; African American, northern European, and females are at greater risk; many patients are asymptomatic. Systemic lupus erythematosus may affect any organ system; women of childbearing age are at increased risk. Idiopathic pulmonary fibrosis is a rare interstitial lung disease, with smokers at increased risk for pulmonary malignancy; survival is usually 2 to 3 years from diagnosis; no effective treatment exists, with lung transplant the only therapeutic option. Acute respiratory distress syndrome (ARDS) is associated with underlying critical illness or injury, developing acutely in 1 to 2 days; mortality is 25% to 35%. Pulmonary histiocytosis X is an interstitial lung disease associated with cigarette smoking and an unpredictable course; some spontaneous remission occurs. Lymphangioleiomyomatosis involves progressive deterioration of lung function, associated with tuberous sclerosis and exacerbated by pregnancy, with women at increased risk; possible spontaneous pneumothorax and chylothorax; death usually results from respiratory failure. Ankylosing spondylitis is a genetic inflammatory process resulting in fusion of axial skeleton and spinal deformities, with men at increased risk; radiologic bamboo spine, sacral to cervical progression, and restrictive lung disease with high reliance on diaphragm; extraskeletal manifestations may occur. Kyphosis (exaggerated anterior flexion) and scoliosis (lateral rotational deformity) are spinal/rib cage deformities with idiopathic, congenital, or neuromuscular etiology; corrective surgery done if Cobb thoracic angle >50% lumbar angle >40%. Bleomycin is an antineoplastic antibiotic used in combination chemotherapy, with no myelosuppressive effect; toxicity can cause life-threatening pulmonary fibrosis. Influenza A is highly infectious, presenting with flulike symptoms and possible progression to ARDS; human-to-human exposure is through droplets or contaminated surfaces, with high risk for infants, children, pregnancy, chronically ill, or renal replacement therapy patients. No prophylactic treatment exists; treat patients with high index of suspicion without definitive testing; rRT-PCR and viral cultures are sensitive for pandemic H1N1 strain. Severe acute respiratory syndrome (SARS) is highly infectious, transmitted by coronavirus with human-to-human exposure via droplets or surfaces, and may progress to ARDS. Echinococcal disease of lung is from canine tapeworm, transmitted by eggs from feces; rupture of cyst may result in anaphylactic reaction or spread of disease to other organs; children are at increased risk. No transthoracic needle aspiration is done; surgery is only option.

Abstract
Non-invasive positive pressure ventilation or non-invasive ventilation (NIV) has emerged as a simpler and safer alternative to invasive mechanical ventilation in patients developing acute postoperative respiratory failure. The benefits of NIV as compared to intubation and mechanical ventilation include lower complications, shorter duration of hospital stay, reduced morbidity, lesser cost of treatment and even reduced mortality rates. However, its use may not be uniformly applicable in all patient groups. This article reviews the indications, contraindications and evidence supporting the use of NIV in individual patient groups in the postoperative period. The anaesthesiologist needs to recognise the subset of patients most likely to benefit from NIV therapy so as to apply it most effectively. It is equally important to promptly identify signs of failure of NIV therapy and be prepared to initiate alternate ways of respiratory support. The author searched PubMed and Ovid MEDLINE, without date restrictions. Search terms included Non-invasive ventilation, postoperative and respiratory failure. Foreign literature was included, though only articles with English translation were used.

Abstract
BACKGROUND Postoperative pulmonary complications, generally defined as any pulmonary abnormality occurring in the postoperative period, are still a significant issue in clinical practice increasing hospital length of stay, morbidity and mortality. Non-invasive ventilation (NIV), primarily applied in cardiogenic pulmonary edema, decompensated COPD and hypoxemic pulmonary failure, is nowadays also used in perioperative settings. OBJECTIVE Investigate the application and results of preventive and therapeutic NIV in postsurgical patients. DESIGN A systematic review. DATA SOURCES Medical literature databases were searched for articles about "clinical trials," "randomized controlled trials" and "meta-analyses." The keywords "cardiac surgery," "thoracic surgery," "lung surgery," "abdominal surgery," "solid organ transplantation," "thoraco-abdominal surgery" and "bariatric surgery" were combined with any of these: "non-invasive positive pressure ventilation," "continuous positive airway pressure," "bilevel ventilation," "postoperative complications," "postoperative care," "respiratory care," "acute respiratory failure," "acute lung injury" and "acute respiratory distress syndrome." RESULTS Twenty-nine articles (N=2,279 patients) met the inclusion criteria. Nine studies evaluated NIV in post-abdominal surgery, three in thoracic surgery, eight in cardiac surgery, three in thoraco-abdominal surgery, four in bariatric surgery and two in post solid organ transplantation used both for prophylactic and therapeutic purposes. NIV improved arterial blood gases in 15 of the 22 prophylactic and in 4 of the 7 therapeutic studies, respectively. NIV reduced the intubation rate in 11 of the 29 studies and improved outcome in only 1. CONCLUSIONS Despite these limited data and the necessity of new randomized trials, NIV could be considered as a prophylactic and therapeutic tool to improve gas exchange in postoperative patients.

Abstract
Hip fracture is a common injury among the elderly. Although patients who receive hip fracture surgery carry the best functional recovery compared to other treatment modalities, the presence of postoperative pulmonary complications, such as atelectasis, pneumonia, and pulmonary thromboembolism, may contribute to increased length of hospital stay, perioperative morbidity, and mortality. This review aims to provide evidence-based recommendations for preoperative assessment and perioperative strategies to reduce the risk of pulmonary complications after hip fracture surgery. Clinical assessment and basic laboratory results are sufficient to stratify the risk of postoperative pulmonary complications. Well-documented risk factors for pulmonary complications include advanced age, poor general health status, current infections, pre-existing cardiopulmonary diseases, hypoalbuminemia, and impaired renal function. Apart from optimizing the patient's medical conditions, interventions such as lung expansion maneuvers and thromboprophylaxis have been proven to be effective in reducing the risk of pulmonary complications after hip fracture surgery.

Abstract
Pressure ulceration, deep venous thromboembolism, and hospital-acquired pneumonia are well-known complications of bed rest. This retrospective, single-center, observational cohort study evaluated the effectiveness of instituting bed rest protocol that included specific positioning, continuous heel off-loading, recumbent upper and lower body bed exercises, scheduled incentive spirometry, frequent position changes, and thromboprophylaxis (chemical, mechanical, or both), in reducing the incidence of pressure ulceration, deep venous thromboembolism, and hospital-acquired pneumonia in consecutive patients admitted for at least 7 days. A total of 29 patients (24 males, 5 females) were included in this study, with a mean age of 62.5 (median 63, range 17 to 84) years. The mean length of bed rest was 13.1 (median 10, range 7 to 31) days; and, the mean length of hospital stay was 21.1 (median 17, range 8 to 72) days. During hospitalization, 2 (6.9%) patients developed one or more of the complications measured, with 1 developing a posterior heel pressure ulcer that resolved with local care and another who developed deep venous thrombosis without pulmonary embolism, managed with therapeutic anticoagulation, and hospital-acquired pneumonia treated with antibiotic therapy. The results of this analysis were favorable in comparison with previously reported incidence rates for pressure ulcer, deep venous thrombosis, and hospital-acquired pulmonary complications in patients with similar risk factors, and suggested that a prescribed bed protocol reduces complications associated with bed rest.
