Abstract

RationaleFollowing acute respiratory distress syndrome (ARDS), joblessness is common but poorly understood.ObjectivesTo evaluate the timing of return to work after ARDS, and associated risk factors, lost earnings, and changes in healthcare coverage Methods: Over 12-month longitudinal follow-up, ARDS survivors from 43 U.S. ARDSNet hospitals provided employment and healthcare coverage data via structured telephone interviews. Factors associated with the timing of return to work were assessed using Fine and Gray regression analysis. Lost earnings were estimated using Bureau of Labor Statistics data.Measurements and main resultsOf 922 consenting survivors, 386 (42%) were employed before ARDS (56% male; mean ± SD age, 45 ± 13 yr), with seven dying by 12-month follow-up. Of 379 previously employed 12-month survivors, 166 (44%) were jobless at 12-month follow-up. Accounting for competing risks of death and retirement, half of enrolled and previously employed survivors returned to work by 13 weeks after hospital discharge, with 68% ever returning by 12 months. Delays in return to work were associated with longer hospitalization and older age among nonwhite survivors. Over 12-month follow-up, 274 (71%) survivors accrued lost earnings, averaging $26,949 ± $22,447 (60% of pre-ARDS annual earnings). Jobless survivors experienced a 14% (95% confidence interval, 5-22%; P = 0.002) absolute decrease in private health insurance (from 44% pre-ARDS) and a 16% (95% confidence interval, 7-24%; P

Abstract

Background: Current management practices and outcomes in weaning from invasive mechanical ventilation are poorly understood. We aimed to describe the epidemiology, management, timings, risk for failure, and outcomes of weaning in patients requiring at least 2 days of invasive mechanical ventilation. Methods: WEAN SAFE was an international, multicentre, prospective, observational cohort study done in 481 intensive care units in 50 countries. Eligible participants were older than 16 years, admitted to a participating intensive care unit, and receiving mechanical ventilation for 2 calendar days or longer. We defined weaning initiation as the first attempt to separate a patient from the ventilator, successful weaning as no reintubation or death within 7 days of extubation, and weaning eligibility criteria based on positive end-expiratory pressure, fractional concentration of oxygen in inspired air, and vasopressors. The primary outcome was the proportion of patients successfully weaned at 90 days. Key secondary outcomes included weaning duration, timing of weaning events, factors associated with weaning delay and weaning failure, and hospital outcomes. This study is registered with ClinicalTrials.gov, NCT03255109. Findings: Between Oct 4, 2017, and June 25, 2018, 10 232 patients were screened for eligibility, of whom 5869 were enrolled. 4523 (77·1%) patients underwent at least one separation attempt and 3817 (65·0%) patients were successfully weaned from ventilation at day 90. 237 (4·0%) patients were transferred before any separation attempt, 153 (2·6%) were transferred after at least one separation attempt and not successfully weaned, and 1662 (28·3%) died while invasively ventilated. The median time from fulfilling weaning eligibility criteria to first separation attempt was 1 day (IQR 0–4), and 1013 (22·4%) patients had a delay in initiating first separation of 5 or more days. Of the 4523 (77·1%) patients with separation attempts, 2927 (64·7%) had a short wean (≤1 d

Abstract

Objectives: To develop evidence-based recommendations for clinicians caring for adults with acute liver failure (ALF) or acute on chronic liver failure (ACLF) in the ICU., Design: The guideline panel comprised 27 members with expertise in aspects of care of the critically ill patient with liver failure or methodology. We adhered to the Society of Critical Care Medicine standard operating procedures manual and conflict-of-interest policy. Teleconferences and electronic-based discussion among the panel, as well as within subgroups, served as an integral part of the guideline development., Interventions: In part 2 of this guideline, the panel was divided into four subgroups: neurology, peri-transplant, infectious diseases, and gastrointestinal groups. We developed and selected Population, Intervention, Comparison, and Outcomes (PICO) questions according to importance to patients and practicing clinicians. For each PICO question, we conducted a systematic review and meta-analysis where applicable. The quality of evidence was assessed using the Grading of Recommendations Assessment, Development, and Evaluation approach. We used the evidence to decision framework to facilitate recommendations formulation as strong or conditional. We followed strict criteria to formulate best practice statements., Measurements and Main Results: We report 28 recommendations (from 31 PICO questions) on the management ALF and ACLF in the ICU. Overall, five were strong recommendations, 21 were conditional recommendations, two were best-practice statements, and we were unable to issue a recommendation for five questions due to insufficient evidence., Conclusions: Multidisciplinary, international experts formulated evidence-based recommendations for the management ALF and ACLF patients in the ICU, acknowledging that most recommendations were based on low quality and indirect evidence., Competing Interests: Conflicts of interest were reviewed and adjudicated by the co-chairs and co-vice chairs of the guidelines. In the event an individual disclosed a conflict or potential conflict by submitted form or verbally during the process of guidelines, those individuals abstained from voting on related questions. The taskforce followed all procedures as documented in the American College of Critical Care Medicine/Society of Critical Care Medicine (SCCM) Standard Operating Procedures Manual. Drs.

Abstract

How to deliver best care in various clinical settings remains a vexing problem. All pertinent healthcare-related questions have not, cannot, and will not be addressable with costly time- and resource-consuming controlled clinical trials. At present, evidence-based guidelines can address only a small fraction of the types of care that clinicians deliver. Furthermore, underserved areas rarely can access state-of-the-art evidence-based guidelines in real-time, and often lack the wherewithal to implement advanced guidelines. Care providers in such settings frequently do not have sufficient training to undertake advanced guideline implementation. Nevertheless, in advanced modern healthcare delivery environments, use of eActions (validated clinical decision support systems) could help overcome the cognitive limitations of overburdened clinicians. Widespread use of eActions will require surmounting current healthcare technical and cultural barriers and installing clinical evidence/data curation systems. The authors expect that increased numbers of evidence-based guidelines will result from future comparative effectiveness clinical research carried out during routine healthcare delivery within learning healthcare systems., (© The Author(s) 2022.

Abstract

Background: The cuff leak test (CLT) is used to assess laryngeal edema prior to extubation. There is limited evidence for its diagnostic accuracy and conflicting guidelines surrounding its use in critically ill patients who do not have risk factors for laryngeal edema. The primary study aim was to describe intensivists' beliefs, attitudes, and practice regarding the use of the CLT., Methods: A 13-item survey was developed, pilot-tested, and subjected to clinical sensibility testing. The survey was distributed electronically through MetaClinician®. Descriptive statistics and multivariable regression analysis were performed to examine associations between participant demographics and survey responses., Results: 1184 practicing intensivists from 17 countries in North and South America, Europe, Oceania, and Asia participated. The majority (59%) of respondents reported rarely or never perform the CLT prior to extubating patients not at high risk of laryngeal edema, which correlated with 54% of respondents reporting they believed a failed CLT did not predict reintubation. Intensivists from the Middle East were 2.4 times more likely to request a CLT compared to those from North America. Intensivists with base training in medicine or emergency medicine were more likely to request a CLT prior to extubation compared to those with base training in anesthesiology., Conclusion: Use of the CLT prior to extubating patients not at high risk of laryngeal edema in the intensive care unit is highly variable. Practice appears to be influenced by country of practice and base specialty training., (© 2021 Acta Anaesthesiologica Scandinavica Foundation.)

Abstract

Objective: Poor sign-out or handover of care may lead to preventable patient harm. Critically ill patients in intensive care units (ICU) are complex and prone to rapid clinical deterioration. If clinical deterioration occurs, timeliness of appropriate interventions is essential to prevent or reduce adverse outcomes. Therefore sign-outs need to efficiently transmit key information and provide anticipatory guidance. Interventions to improve resident-to-resident ICU sign-outs have not been well described. We conducted a controlled trial to test the effectiveness of a standardised ICU sign-out process to the usual ICU sign-out., Design: Prospective controlled trial., Setting: A 26-bed medical intensive care unit (MICU) in an urban tertiary academic medical centre., Subjects: Residents rotating through the MICU., Interventions: ICU-specific written sign-out template., Methods: Residents completed postcall surveys assessing satisfaction with verbal and written sign-outs and incidence of non-routine events. Our main outcome of interest was the occurrence of non-routine events., Main Results: Compared with the intervention group, on significantly more nights, night float residents in the control group encountered patients who were sicker than sign-out would have suggested (15.94% vs 43.75%; p<0.0001). On significantly fewer nights, night float residents in the intervention group indicated that either something happened to patients that was unexpected (18.84% vs 36.51%; p=0.023) or they were insufficiently prepared for (4.35% vs 35.94%; p<0.0001). Similarly, on fewer nights, residents in the intervention group indicated that they had to perform interventions that were unplanned or unanticipated (15.9% vs 37.7%; p=0.005)., Conclusion: A structured sign-out process compared with usual sign-out significantly reduced the occurrence of non-routine events in an academic MICU., Competing Interests: Competing interests: None declared., (© Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Abstract

Unlabelled: While statins are indicated to reduce blood cholesterol levels, they also have anti-inflammatory and immunomodulatory effects. Several observational cohort studies suggested that statins may improve survival and reduce complications in patients with sepsis. Recent randomized controlled studies in critically ill patients have been conducted and published. In this paper we present a meta-analysis of these randomized trials., Methods: An electronic article search through PubMed was performed. Only randomized controlled trials including critically ill adult patients with severe sepsis were retained. A meta-analysis was performed as detailed in text below. Overall analysis including 1818 patients total from 4 studies showed that there was no difference in 60-day mortality between statins (223/903) and placebo (233/899) [risk ratio, 0.930; 95% CI, 0.722 to 1.198]. Similarly, no difference in 28-day mortality was observed between groups (statins 191/907, placebo 199/911; risk ratio 0.953; 95% CI, 0.715 to 1.271). The results of this meta-analysis confirm that the use of statin therapy should not be recommended in the management of severe sepsis in critically ill patients. Statins should be continued with caution and only if necessary, as one study reported that the statin group had a higher rate of hepatic and renal failure.

Abstract

Objectives: Adult studies have demonstrated the relationship between fluid overload and poor outcomes in acute lung injury/acute respiratory distress syndrome. The approach of pediatric intensivists to fluid management in acute lung injury/acute respiratory distress syndrome and its effect on outcomes is less clear. In a post hoc analysis of our Calfactant in Acute Respiratory Distress Syndrome trial, we examined the relationship of fluid balance to in-hospital outcomes in subjects with acute lung injury/acute respiratory distress syndrome., Design: Calfactant in Acute Respiratory Distress Syndrome was a masked randomized controlled trial of calfactant surfactant versus placebo in pediatric patients with acute lung injury/acute respiratory distress syndrome due to direct lung injury. Caregivers were encouraged to follow a conservative fluid management guideline based on the adult Fluid and Catheter Treatment Trial. Daily fluid balance was collected for the first 7 days after trial enrollment and correlated with clinical outcomes., Patients and Setting: Children admitted to PICUs with acute lung injury/acute respiratory distress syndrome from 24 children's hospitals in six different countries., Intervention: Post hoc analysis of daily fluid balance in subjects from the Pediatric Calfactant in Acute Respiratory Distress Syndrome trial., Measurements and Main Results: Despite the conservative fluid guideline, fluid management was more consistent with a "liberal" approach. On average, study subjects accumulated 1.96 ± 4.2 L/m over the first 7 days of the trial. Subjects who died accumulated on average 8.7 ± 9.5 L/m versus 1.2 ± 2.4 L/m in survivors. Increasing fluid accumulation was associated with fewer ventilator-free days and worsening oxygenation. Multivariable regression models that included age, gender, Pediatric Risk of Mortality score, initial oxygen saturation index and PaO2/FIO2 ratio, injury category, and treatment arm failed to account for the differences in fluid management., Conclusions: Pediatric intensivists generally follow a "liberal" approach to fluid management in children with acute lung injury/acute respiratory distress syndrome. Illness severity or oxygenation disturbance did not explain differences in fluid accumulation but such accumulation was associated with worsening oxygenation, a longer ventilator course, and increased mortality. A more conservative approach to fluid management may improve outcomes in children with acute lung injury/acute respiratory distress syndrome.

Abstract

Because of the physiological stresses of commercial air travel, the presence of a pneumothorax has long been felt to be an absolute contraindication to flight. Additionally, most medical societies recommend that patients wait at least 2 weeks after radiographic resolution of the pneumothorax before they attempt to travel in a nonurgent fashion via commercial air transport. This review sought to survey the current body of literature on this topic to determine if a medical consensus exists; furthermore, this review considered the scientific support, if any, supporting these recommendations. In this review, we found a paucity of data on the issue and noted only a handful of prospective and retrospective studies; thus, true evidence-based recommendations are difficult to develop at this time. We have made recommendations, when possible, addressing the nonurgent commercial air travel for the patient with a recent pneumothorax. However, more scientific research is necessary in order to reach an evidence-based conclusion on pneumothoraces and flying., (Copyright © 2013 Air Medical Journal Associates.

Abstract

Rationale: Our previous studies in children with acute lung injury/acute respiratory distress syndrome demonstrated improved outcomes with exogenous surfactant (calfactant) administration. Sample sizes in those studies were small, however, and the subject populations heterogeneous, thus making recommendations tenuous., Objective: To investigate the efficacy of surfactant administration in a larger, more homogenous population of children with lung injury/acute respiratory distress syndrome due to direct lung injury., Design and Setting: Masked, randomized, placebo-controlled trial in 24 children's hospitals in six different countries., Patients and Methods: Children 37 weeks postconception to 18 years old with lung injury/acute respiratory distress syndrome due to direct lung injury were randomized to receive up to three doses of 30 mg/cm height of surfactant (calfactant) versus placebo (air) within 48 hours of intubation and initiation of mechanical ventilation. The primary outcome was mortality at 90 days. Ventilator-free days, changes in oxygenation, and adverse events were also assessed., Results: The study was stopped at the sponsor's request after the second interim analysis for presumed futility. A total of 110 subjects were enrolled, with consent withdrawn from one whose data are unavailable. There were no significant differences between groups except in hospital-free days (10.4 ± 7.8 placebo vs 6.4 ± 7.8 surfactant; p = 0.01). Overall 90-day mortality was 11% (seven surfactant, five placebo). No immediate improvement in oxygenation was associated with surfactant administration., Conclusions: Surfactant did not improve outcomes relative to placebo in this trial of children with direct lung injury/acute respiratory distress syndrome. Differences in concentration of the surfactant, failure to recruit the lung during surfactant administration, or using two rather than four position changes during administration are possible explanations for the difference from previous studies. Exogenous surfactant cannot be recommended at this time for children with direct lung injury/acute respiratory distress syndrome.

Abstract

Unnecessary variation in clinical care and clinical research reduces our ability to determine what healthcare interventions are effective. Reducing this unnecessary variation could lead to further healthcare quality improvement and more effective clinical research. We have developed and used electronic decision support tools (eProtocols) to reduce unnecessary variation. Our eProtocols have progressed from a locally developed mainframe computer application in one clinical site (LDS Hospital) to web-based applications available in multiple languages and used internationally. We use eProtocol-insulin as an example to illustrate this evolution. We initially developed eProtocol-insulin as a local quality improvement effort to manage stress hyperglycemia in the adult intensive care unit (ICU). We extended eProtocol-insulin use to translate our quality improvement results into usual clinical care at Intermountain Healthcare ICUs. We exported eProtocol-insulin to support research in other US and international institutions, and extended our work to the pediatric ICU. We iteratively refined eProtocol-insulin throughout these transitions, and incorporated new knowledge about managing stress hyperglycemia in the ICU. Based on our experience in the development and clinical use of eProtocols, we outline remaining challenges to eProtocol development, widespread distribution and use, and suggest a process for eProtocol development. Technical and regulatory issues, as well as standardization of protocol development, validation and maintenance, need to be addressed. Resolution of these issues should facilitate general use of eProtocols to improve patient care.

Abstract

Rationale and Objectives: The aim of this study was to determine the efficacy of hyperpolarized (3)He (HHe) ventilation and apparent diffusion coefficient (ADC) HHe magnetic resonance imaging (MRI) in detecting changes in lung function and microstructure in emphysematous lung after bronchial valve (BV) placement., Materials and Methods: One patient diagnosed with emphysema had nine BVs placed in upper lobe bronchi. Imaging was performed before and 6 months after BV placement. Coronal HHe ventilation MRI was used to assess volume changes in the ventilated portions of the lung. Coronal ADC HHe MRI, acquired with b value pairs of 0 and 1.6 s/cm(2) during a second 10-second breath-hold, was used to compute ADC values., Results: HHe ventilation MRI revealed decreased ventilation in the treated segments of the upper lobes after BV placement. Increased ventilation in the lower lobes and two untreated segments of the left upper lobes were also observed, with an upward shift of the major fissure of the right lung. Whole-lung mean ADC decreased by 6.3% from baseline, from 0.48 ± 0.196 to 0.45 ± 0.176 cm(2)/s (toward healthier values) following BV placement., Conclusions: HHe ventilation MRI detected an increase in whole-lung volume and an interlobar fissure shift indicative of increased ventilation of lower relative to upper lobes. Reduced ADC values suggest increased ventilation to healthy lower lobes at the expense of more diseased, expanded alveolar spaces in the upper lobes distal to BV placement. These results suggest that this ionizing radiation-free method of examining the lungs may offer functional and structural information useful in BV intervention planning., (Copyright © 2011 AUR.

Abstract

The respiratory system rarely limits exercise in the normal subject. In patients with chronic pulmonary processes or in the elite athlete, however, the respiratory system may indeed be the limiting factor. Common respiratory disorders include chest pain syndromes, cough, exercise-induced asthma, and vocal cord dysfunction. Chronic lung diseases such as asthma, COPD, and interstitial lung disease impact exercise capacity and endurance. Exercise testing can be useful to distinguish acute and chronic pulmonary causes of dyspnea during exercise, as well as to differentiate between cardiac and pulmonary causes.

Abstract

Tracheostomy continues to be a standard procedure for the management of long-term ventilator-dependent patients. Traditionally the procedure has been performed by surgeons in the operating theater using an open technique. This routine practice has recently been challenged by the introduction of bedside percutaneous dilatational tracheostomy (PDT), which has been reported to be a cost-effective alternative. The purpose of this study is to evaluate and compare the safety, procedure time, cost, and utilization of percutaneous and surgical tracheostomies at a university hospital. A retrospective medical chart review was performed on all ventilator-dependent intensive care unit patients at the University of Virginia Medical Center undergoing tracheostomy during a 23-month period beginning December 26, 1996. Of the 213 patients identified for review, 74 and 139 patients received percutaneous and surgical tracheostomies, respectively. Of 74 percutaneous tracheostomies, 73 reviewed were performed by general surgeons, pulmonary physicians, or anesthesiologists in the intensive care unit; all open tracheostomies were performed by surgeons in the operating room, and one percutaneous procedure was performed in the operating room. Perioperative complications occurred in five of 74 patients (6.76%) during PDT; of these, three patients (4.1%) experienced major complications requiring emergent operative exploration of the neck. Three patients (2.2%) experienced perioperative complications during surgical tracheostomy. The mean procedure time was significantly shorter for the percutaneous procedure. Average charges per patient in an uncomplicated case including professional fees, inventory, bronchoscopy (if performed), and operating room charges were $1753.01 and $2604.00 for percutaneous and standard tracheostomies, respectively. These charges do not include the charges associated with surgical intervention after PDT complications. In contrast to previously published reports showing complications clustered during a physician's first 30 percutaneous cases, our study demonstrated no relationship between complication occurrence and physician experience. That is, no learning curve associated with performing PDT was evident. In addition there was no association seen between physician specialty and complication rate. PDT in the intensive care unit costs less than surgical tracheostomy performed in the operating room and can be performed in less time. Several other studies have recommended that bronchoscopy during PDT provides additional safety; however, in our series all three major complications took place during bronchoscopy-assisted percutaneous procedures. Our series suggests that PDT carries an appreciable risk of major complications. Careful patient selection and additional experience with the procedure may decrease complication rates to an acceptable level.

Abstract

Thirty-two magnetic resonance imaging examinations of the lungs were performed in 16 subjects after inhalation of 1-2 L of helium 3 gas that was laser polarized to 10%-25%. The distribution of the gas was generally uniform, with visualization of the fissures in most cases. Ventilation defects were demonstrated in smokers and in a subject with allergies. The technique has potential for evaluating small airways disease.

Abstract

Objective: To determine the incidence of obstruction and colonization in adult patients in the surgical and medical intensive care units who received inner cannula changes daily versus those who did not., Design: Quasi-experimental prospective study using a convenience sample of patients randomly assigned to one of two methods., Setting: Mid-Atlantic university-affiliated tertiary care center., Patients: Sixty patients within 24 hours of receiving a surgical tracheostomy., Outcome Measures: Obstruction and bacterial colonization of inner cannula., Interventions: All inner cannulas were checked daily for obstruction and cultured on postoperative days 1 and 3., Results: No statistically significant difference was noted in colonization (p = 0.13) between protocols, and no obstructions were noted in either., Conclusion: The study suggests that the routine practice in critical care units of changing tracheostomy inner cannulas may be unnecessary. Although the results of this study are limited, and may not be generalized to other populations, it demonstrates that practice standards related to the care of tracheostomy inner cannula need to be challenged.

Abstract

Background: Outcomes management that uses critical pathways may decrease costs while improving outcomes for patients who require prolonged mechanical ventilation., Objective: To study the efficacy of an outcomes-managed approach to weaning patients from prolonged (more than 3 days) mechanical ventilation., Methods: A method of multidisciplinary care delivery was designed that included an outcomes manager, a care pathway for patients receiving mechanical ventilation, and weaning protocols. Data collection consisted of three parts: a retrospective review of 124 patients who required prolonged ventilation during a 1-year period before implementation of the care model, a 6-month prospective study in which 91 patients were alternately assigned by month to an outcomes-managed approach or a non-outcomes-managed approach, and a 6-month prospective study of 90 patients in which an outcomes-managed approach without alternate-month assignment was used., Results: Outcomes management had no significant effect on total duration of mechanical ventilation or length of stay in the hospital, days of mechanical ventilation without tracheostomy, days of mechanical ventilation with tracheostomy, or outcome (weaned, withdrawal from mechanical ventilation, death, or transfer without weaning). However, duration of mechanical ventilation was 1.3 days shorter, length of stay in the hospital was 2.1 days shorter, and the cost per case was $ 3341 less for patients in the outcomes-managed group than for patients in the non-outcomes-managed group., Conclusion: Outcomes-managed care did not have a significant effect on duration of ventilation, length of stay in the hospital, or outcome in patients receiving long-term mechanical ventilation.

Abstract

Objective: A clinical study was undertaken to define optimal preoperative strategies and intraoperative techniques that would result in the least morbidity and maximum physiologic improvements in patients with end-stage emphysema selected for lung volume reduction surgery., Background: Lung volume reduction surgery recently has been advocated as an alternative or a bridge to lung transplantation for patients with end-stage chronic obstructive pulmonary disease. The risks, benefits, and long-term results have not been clarified., Methods: Twenty-six patients underwent lung volume reduction surgery with a 3-month follow-up on 17 patients. Preoperative and postoperative changes in pulmonary function parameters, quality of life, and oxygen requirement were analyzed. The value of preoperative localization of diseased lung segments and how this affects intraoperative resection is addressed., Results: Forty-nine percent improvement in FEV1 (forced expiratory volume in 1 second) and 23% improvement in FVC (forced vital capacity) were seen after lung volume reduction surgery. Supplemental oxygen requirement was decreased and 79% of patients reported a much better quality of life. Mortality was 3.8% and air leak morbidity was 18%., Conclusions: Lung volume reduction surgery can predictably improve objective and subjective pulmonary function in selected patients with end-stage emphysema with low morbidity and mortality. Careful patient selection, accurate preoperative localization of diseased target areas, skilled anesthetic technique, meticulous operative approach, and intense postoperative support are essential to achieve favorable results.

Abstract

Background: Despite extensive data acquired in the area of weaning, clinicians still struggle with the questions of how and when to begin the process. Clinical weaning indices, designed to predict weaning potential, are often difficult to use. They provide an answer at a specific time; extrapolation to the weaning process is rarely possible. No single index has proven to be superior., Objectives: To test the efficacy of five clinical weaning indices (Burns Weaning Assessment Program; Weaning Index; frequency tidal volume ratio; compliance, resistance, oxygenation and pressure index; and negative inspiratory pressure) at regular intervals during withdrawal of ventilatory support and to determine threshold levels for the program., Methods: A prospective convenience sample consisted of 37 adult critical care patients requiring mechanical ventilation for at least 7 days and identified as stable and ready to wean. Data were collected on all weaning indices every other day until the patient was weaned., Results: With the exception of the Burns Weaning Assessment Program, weaning indices did not change significantly from preweaning scores. Furthermore, the results failed to demonstrate that any of the five clinical weaning indices have strong predictive power related to weaning trial outcomes, although all the indices had negative predictive values that may be helpful in predicting unsuccessful weaning trials., Conclusions: The results of this study suggest that the process of weaning may be enhanced by comprehensive, systematic approaches and that clinical weaning indices like the Burns Weaning Assessment Program might best serve as tools to track trends in progress, keep care planning on target, and prevent unsuccessful weaning trials.

Abstract

Atelectasis is a major factor in postoperative morbidity for patients undergoing cardiopulmonary surgery. We evaluated the effectiveness of stacked inspiratory spirometry (STIS) in 17 patients status postcoronary artery bypass graft in a nonrandomized fashion. We measured pulmonary shunt as an endpoint, and compared the magnitudes before and after the STIS maneuver. Our results showed an 8.66 percent reduction in pulmonary shunt (p < 0.05). The reduction in shunt was modest; however, repetitive maneuvers might result in greater improvement.

Abstract

Bedside monitoring of respiratory status is designed to measure specific parameters and alert the clinician when these parameters exceed the limits of a desired range. Parameters should include measures of respiratory mechanics, oxygenation, and ventilation. Monitoring is the only form of communication between the physician and a patient receiving neuromuscular blocking agents. Airway pressure tracing alone, or in conjunction with concurrent flow, measures respiratory system mechanics, resistance, compliance, and the work of breathing. Pulse oximetry reflects oxygenation, while mixed venous oximetry indicates the balance between oxygen supply and demand. Capnography is a noninvasive way of assessing ventilation. Taken as a whole, noninvasive monitoring provides useful information, reflecting trends in oxygenation, ventilation, and mechanics. This article reviews the concepts of noninvasive monitoring of critically ill patients. Emphasis is given to the patient receiving neuromuscular blocking agents.

Abstract

The maximal pressure that can be generated during an inspiratory effort against an occluded airway serves as an index of respiratory muscle strength. We devised a method that permits accurate measurement of MIP, with near maximal values, and does not require patient cooperation. Twenty-two critically ill intubated patients performed MIP maneuvers before and after coaching. For the initial 11 patients, MIP was measured after the airway was occluded in 20 s with a one-way valve that permitted only exhalation. In the latter 11 patients, DS (approximately 1/3 VT) was added in an effort to increase respiratory drive before the noncoached MIP maneuver. We found no significant difference between coached and noncoached MIP maneuvers when P0.1 during the first 100 ms of inspiratory efforts prior to the noncoached MIP maneuver was greater than 2 cm H2O. Thus, MIP can be reliably measured in critically ill patients with or without coaching.

Abstract

We hypothesized that the ventilatory capacity needed to wean from mechanical ventilation (mv) depends on two variables: ventilatory endurance and the efficiency of gas exchange. We also hypothesized that these variables could be assessed from data readily available at the bedside, including tidal volume (VT) on mv and during spontaneous breathing (sb), ventilator peak inspiratory pressure (Ppk), and patient negative inspiratory pressure (NIP). Ventilatory endurance was evaluated using a modified pressure-time index: PTI = TI/Ttot x Pbreath/NIP, where Pbreath = Ppk x VTsb/VTmv. Defining VE40 as the minute ventilation needed to bring PaCO2 to 40 mm Hg, the efficiency of gas exchange was evaluated by calculating VE40/VTsb = (VE x PaCO2)mv/VTsb x 40. Because high levels of inspiratory effort might cause patients to reduce VTsb and thereby compromise CO2 elimination, we devised a weaning index (WI) that combines ventilatory endurance and the efficiency of gas exchange: WI = PTI x (VE40/VTsb). The study population comprised 38 patients with chronic obstructive pulmonary disease, adult respiratory distress syndrome, pneumonia, neuromuscular disease, and miscellaneous other conditions. They had been mechanically ventilated more than 3 days and were considered by clinical criteria to be ready for weaning. Of 46 weaning trials, 19 were successful, 2 were partially successful, and 25 failed. PTI and VE40/VTsb were higher in patients who failed (p less than 0.05), but neither variable alone had sufficient sensitivity or specificity to predict the outcome of weaning trials accurately.(ABSTRACT TRUNCATED AT 250 WORDS)
