RESUMEN
Unplanned extubations (UE) frequently occur in critical care units. These events are precipitated by many risk factors and are associated with adverse outcomes for patients. We reviewed the current literature to examine factors related to UE and presented the analysis of 41 articles critical to the topic. Our review has identified specific risk factors that we discuss in this review, such as sedation strategies, physical restraints, endotracheal tube position, and specific nursing care aspects associated with an increased incidence of UE. We recommend interventions to reduce the risk of UE. However, we recommend that bundled rather than a single intervention is likely to yield higher success, given the heterogeneity of factors contributing to increasing the risk of UE.
RESUMEN
BACKGROUND: Calcium release-activated calcium (CRAC) channel inhibitors block proinflammatory cytokine release, preserve endothelial integrity and may effectively treat patients with severe COVID-19 pneumonia. METHODS: CARDEA was a phase 2, randomized, double-blind, placebo-controlled trial evaluating the addition of Auxora, a CRAC channel inhibitor, to corticosteroids and standard of care in adults with severe COVID-19 pneumonia. Eligible patients were adults with ≥ 1 symptom consistent with COVID-19 infection, a diagnosis of COVID-19 confirmed by laboratory testing using polymerase chain reaction or other assay, and pneumonia documented by chest imaging. Patients were also required to be receiving oxygen therapy using either a high flow or low flow nasal cannula at the time of enrolment and have at the time of enrollment a baseline imputed PaO2/FiO2 ratio > 75 and ≤ 300. The PaO2/FiO2 was imputed from a SpO2/FiO2 determine by pulse oximetry using a non-linear equation. Patients could not be receiving either non-invasive or invasive mechanical ventilation at the time of enrolment. The primary endpoint was time to recovery through Day 60, with secondary endpoints of all-cause mortality at Day 60 and Day 30. Due to declining rates of COVID-19 hospitalizations and utilization of standard of care medications prohibited by regulatory guidance, the trial was stopped early. RESULTS: The pre-specified efficacy set consisted of the 261 patients with a baseline imputed PaO2/FiO2≤ 200 with 130 and 131 in the Auxora and placebo groups, respectively. Time to recovery was 7 vs. 10 days (P = 0.0979) for patients who received Auxora vs. placebo, respectively. The all-cause mortality rate at Day 60 was 13.8% with Auxora vs. 20.6% with placebo (P = 0.1449); Day 30 all-cause mortality was 7.7% and 17.6%, respectively (P = 0.0165). Similar trends were noted in all randomized patients, patients on high flow nasal cannula at baseline or those with a baseline imputed PaO2/FiO2 ≤ 100. Serious adverse events (SAEs) were less frequent in patients treated with Auxora vs. placebo and occurred in 34 patients (24.1%) receiving Auxora and 49 (35.0%) receiving placebo (P = 0.0616). The most common SAEs were respiratory failure, acute respiratory distress syndrome, and pneumonia. CONCLUSIONS: Auxora was safe and well tolerated with strong signals in both time to recovery and all-cause mortality through Day 60 in patients with severe COVID-19 pneumonia. Further studies of Auxora in patients with severe COVID-19 pneumonia are warranted. Trial registration NCT04345614.

BACKGROUND: Various intensivist staffing models have been suggested, but the long-term sustainability and outcomes vary and may not be sustained. We examined the impact of implementing a high-intensity intensivist coverage model with a nighttime in-house nocturnist (non-intensivist) and its effect on intensive care unit (ICU) outcomes. METHODS: We obtained historical control baseline data from 2007 to 2011 and compared the same data from 2011 to 2015. The Acute Physiological and Chronic Health Evaluation outcomes system was utilized to collect clinical, physiological, and outcome data on all adult patients in the medical ICU and to provide severity-adjusted outcome predictions. The model consists of a mandatory in-house daytime intensivist service that leads multidisciplinary rounds, and an in-house nighttime coverage is provided by nocturnist (nonintensivists) with current procedural skills in airways management, vascular access, and commitment to supervise house staff as needed. The intensivist continues to be available remotely at nighttime for house staff and consultation with the nocturnist. A backup intensivist is available for surge management. RESULTS: First year yielded improved throughput (2428 patients/year to 2627 then 2724 at fifth year). Case mix stable at 53.7 versus 55.2. The ICU length of stay decreased from 4.7 days (predicted 4.25 days) to 3.8 days (4.15) in first year; second year: 3.63 days (4.29 days); third year: 3.24 days (4.37), fourth year: 3.34 days (4.45), and fifth year: 3.61 days (4.42). Intensive care unit <24 hours readmission remained at 1%; >24 hours increased from 4% to 6%. Low-risk monitoring admissions remained at an average 17% (benchmark 17.18%). Intensive care unit mortality improved with standardized mortality ration averaging at 0.84. Resident satisfaction surveys improved. CONCLUSIONS: Implementing an intensivist service with nighttime nocturnist staffing in a high-intensity large teaching hospital is feasible and improved ICU outcomes in a sustained manner that persisted after the initial implementation phase. The model resulted in reduced and sustained observed-to-predicted length of ICU stay.

BACKGROUND: Mechanically ventilated patients may receive more sedation during the night than during the day, potentially delaying extubation. We compared nighttime and daytime benzodiazepine and opioid administration in adult patients enrolled in a multicenter sedation trial comparing protocolized sedation alone or protocolized sedation combined with daily sedation interruption; and we evaluated whether nighttime and daytime doses were associated with liberation from mechanical ventilation. METHODS: This is a secondary analysis of a randomized trial which was conducted in 16 North American medical-surgical ICUs. In all 423 patients, nurses applied a validated sedation scale hourly to titrate benzodiazepine and opioid infusions to achieve a light level of sedation. Using fentanyl equivalents and midazolam equivalents, we compared dosages administered during night (19:00 to 07:00) and day (07:00 to 19:00) shifts. Using multivariable logistic regression we evaluated the association between nighttime and daytime opioid and sedative doses, and spontaneous breathing trial (SBT) conduct, SBT success, and extubation. RESULTS: Nighttime benzodiazepine and opioid doses were significantly higher than daytime doses (mean difference midazolam equivalents 23.3 mg, 95 % CI 12.9, 33.8, p < 0.0001; mean difference fentanyl equivalents 356 mcg, 95 % CI 130, 582, p = 0.0021). Mean Sedation Agitation Scale score was similar between night and day, and was at target (3.2 vs 3.3, 95 % CI -0.05, 0.02, p = 0.35). Self-reported nurse workload was similar during the night and day. Patients were more often restrained during day shifts (76.3 % vs 73.7 %, p < 0.0001), and there were more unintentional device removals during the day compared with night (15.9 % vs 9.1 %, p < 0.0001). Increases in nighttime drug doses were independently associated with failure to meet SBT screening criteria, SBT failure, and the decision not to extubate the patient despite successful SBT. CONCLUSION: Patients received higher doses of opioids and benzodiazepines at night. Higher nighttime doses were associated with SBT failure and delayed extubation. TRIAL REGISTRATION: ClinicalTrials.gov NCT00675363 . Registered 7 May 2008.

OBJECTIVE: Delirium is common during critical illness and associated with adverse outcomes. We compared characteristics and outcomes of delirious and nondelirious patients enrolled in a multicenter trial comparing protocolized sedation with protocolized sedation plus daily sedation interruption. DESIGN: Randomized trial. SETTING: Sixteen North American medical and surgical ICUs. PATIENTS: Four hundred thirty critically ill, mechanically ventilated adults. INTERVENTIONS: All patients had hourly titration of opioid and benzodiazepine infusions using a validated sedation scale. For patients in the interruption group, infusions were resumed, if indicated, at half of previous doses. Delirium screening occurred daily; positive screening was defined as an Intensive Care Delirium Screening Checklist score of 4 or more at any time. MEASUREMENTS AND MAIN RESULTS: Delirium was diagnosed in 226 of 420 assessed patients (53.8%). Coma was identified in 32.7% of delirious compared with 22.7% of nondelirious patients (p = 0.03). The median time to onset of delirium was 3.5 days (interquartile range, 2-7), and the median duration of delirium was 2 days (interquartile range, 1-4). Delirious patients were more likely to be male (61.1% vs 46.6%; p = 0.005), have a surgical/trauma diagnosis (21.2% vs 11.0%; p = 0.030), and history of tobacco (31.5% vs 16.2%; p = 0.002) or alcohol use (34.6% vs 20.9%; p = 0.009). Patients with positive delirium screening had longer duration of ventilation (13 vs 7 d; p < 0.001), ICU stay (12 vs 8 d; p < 0.0001), and hospital stay (24 vs 15 d; p < 0.0001). Delirious patients were more likely to be physically restrained (86.3% vs 76.7%; p = 0.014) and undergo tracheostomy (34.6% vs 15.5%; p < 0.0001). Antecedent factors independently associated with delirium onset were restraint use (hazard ratio, 1.87; 95% CI, 1.33-2.63; p = 0.0003), antipsychotic administration (hazard ratio, 1.67; 95% CI, 1.005-2.767; p = 0.047), and midazolam dose (hazard ratio, 0.998; 95% CI, 0.997-1.0; p = 0.049). There was no difference in delirium prevalence or duration between the interruption and control groups. CONCLUSION: In mechanically ventilated adults, delirium was common and associated with longer duration of ventilation and hospitalization. Physical restraint was most strongly associated with delirium.

OBJECTIVES: To 1) describe factual, emotional, and delusional memories of ICU stay for patients enrolled in the SLEAP (Daily sedation interruption in mechanically ventilated critically ill patients cared for with a sedation protocol) trial; 2) compare characteristics of patients with and without ICU recall, and patients with and without delusional memories; and 3) determine factors associated with delusional memories 28 days after ICU discharge. DESIGN: Prospective cohort. SETTING: Sixteen North American medical and surgical ICUs. PATIENTS: Critically ill, mechanically ventilated adults randomized in the SLEAP trial. INTERVENTIONS: Post-ICU interviews on days 3, 28, and 90 using the validated ICU Memory Tool. MEASUREMENTS AND MAIN RESULTS: Overall, 289 of 297 ICU survivors (97%) (146 protocolized sedation and 143 protocolized sedation plus daily interruption patients) were interviewed at least once. Because there were no differences in recall status or types of memories between the two sedation groups, we present the findings for all patients rather than by study group. On days 3, 28, and 90, 28%, 26%, and 36% of patients, respectively, reported no recall of being in the ICU (overall perception, self-reported) (p = 0.75). Mean daily doses of benzodiazepines and opioids were lower in patients with no ICU recall than those with recall (p < 0.0001 for both). Despite one third of patients reporting no recall of ICU stay on day 3, 97% and 90% reported at least one factual and one emotional memory from ICU, respectively. Emotional memories declined with time after ICU discharge, particularly panic and confusion. Delusional memories 28 days after discharge were common (70%) yet unrelated to delirium (p = 0.84), recall status (p = 0.15), total dose of benzodiazepine (p = 0.78), or opioid (p = 0.21). Delusional memories were less likely with longer duration of mechanical ventilation (odds ratio, 0.955; 95% CI, 0.91-1.00; p = 0.04). CONCLUSIONS: Recall of ICU stay and types of memories reported were not influenced by the trial sedation strategy. Lack of ICU recall and delusional memories were common after ICU discharge despite the use of sedation strategies that promoted wakefulness.

BACKGROUND: Although numerous studies have shown that anticoagulation of nonvalvular atrial fibrillation (AF) significantly decreases the risk of stroke, anticoagulating critically ill patients in the intensive care unit (ICU) poses many challenges and the benefits have not been determined. OBJECTIVE: To assess the safety and efficacy of anticoagulation in AF patients with sepsis. Ascertaining the incidence of complications associated with anticoagulation therapy, such as bleeding, can optimize patient care. METHODS: This was a retrospective observational study to assess the incidence of stroke and anticoagulation-related complications (eg, bleeding, heparin-induced thrombocytopenia) in AF patients with severe sepsis. This study was undertaken in a surgical/medical ICU of a teaching, community-based hospital. A total of 115 patients with AF who were admitted with a diagnosis of sepsis were included in the study. RESULTS: Among 115 patients (mean age 81 ± 9.5 years and CHADS2 [congestive heart failure, hypertension, age >75 years, diabetes mellitus, stroke] score 3.17 ± 1.20), 80 (69.6%) did not receive anticoagulation treatment during their hospitalization and none of these patients developed a stroke. Anticoagulation-related complications occurred more often in the group who received anticoagulation (8.6% [3/35] vs 0%, P = .008). In the anticoagulated group, a majority of the patients were within therapeutic range less than 50% of the time during their ICU stay. There was no statistically significant difference in survival rates during their hospitalization (66.2% [53/80] for the non-anticoagulated group vs 74.3% [26/35] in the anticoagulated group, P = .392). CONCLUSION: Administration of anticoagulation for elderly patients with a CHADS2 score at 2 or more in the setting of sepsis can be associated with an increased risk of anticoagulation-related complications (eg, bleeding, heparin-induced thrombocytopenia). Managing and targeting a therapeutic goal with warfarin therapy in critically ill patients with sepsis is challenging. Further studies are necessary to provide appropriate recommendations in this setting.

BACKGROUND: This update summarizes key changes made to the protocol for the Frequency of Screening and Spontaneous Breathing Trial (SBT) Technique Trial-North American Weaning Collaborative (FAST-NAWC) trial since the publication of the original protocol. This multicenter, factorial design randomized controlled trial with concealed allocation, will compare the effect of both screening frequency (once vs. at least twice daily) to identify candidates to undergo a SBT and SBT technique [pressure support + positive end-expiratory pressure vs. T-piece] on the time to successful extubation (primary outcome) in 760 critically ill adults who are invasively ventilated for at least 24 h in 20 North American intensive care units. METHODS/DESIGN: Protocols for the pilot, factorial design trial and the full trial were previously published in J Clin Trials ( https://doi.org/10.4172/2167-0870.1000284 ) and Trials (https://doi: 10.1186/s13063-019-3641-8). As planned, participants enrolled in the FAST pilot trial will be included in the report of the full FAST-NAWC trial. In response to the onset of the coronavirus disease of 2019 (COVID-19) pandemic when approximately two thirds of enrollment was complete, we revised the protocol and consent form to include critically ill invasively ventilated patients with COVID-19. We also refined the statistical analysis plan (SAP) to reflect inclusion and reporting of participants with and without COVID-19. This update summarizes the changes made and their rationale and provides a refined SAP for the FAST-NAWC trial. These changes have been finalized before completion of trial follow-up and the commencement of data analysis. TRIAL REGISTRATION: Clinical Trials.gov NCT02399267.

CONTEXT: Protocolized sedation and daily sedation interruption are 2 strategies to minimize sedation and reduce the duration of mechanical ventilation and intensive care unit (ICU) stay. We hypothesized that combining these strategies would augment the benefits. OBJECTIVE: To compare protocolized sedation with protocolized sedation plus daily sedation interruption in critically ill patients. DESIGN, SETTING, AND PATIENTS: Randomized controlled trial of 430 critically ill, mechanically ventilated adults conducted in 16 tertiary care medical and surgical ICUs in Canada and the United States between January 2008 and July 2011. INTERVENTION: Continuous opioid and/or benzodiazepine infusions and random allocation to protocolized sedation (n = 209) (control) or to protocolized sedation plus daily sedation interruption (n = 214). Using validated scales, nurses titrated infusions to achieve light sedation. For patients receiving daily interruption, nurses resumed infusions, if indicated, at half of previous doses. Patients were assessed for delirium and for readiness for unassisted breathing. MAIN OUTCOME MEASURE: Time to successful extubation. Secondary outcomes included duration of stay, doses of sedatives and opioids, unintentional device removal, delirium, and nurse and respiratory therapist clinical workload (on a 10-point visual analog scale [VAS]). RESULTS: Median time to successful extubation was 7 days in both the interruption and control groups (median [IQR], 7 [4-13] vs 7 [3-12]; interruption group hazard ratio, 1.08; 95% CI, 0.86-1.35; P = .52). Duration of ICU stay (median [IQR], 10 [5-17] days vs 10 [6-20] days; P = .36) and hospital stay (median [IQR], 20 [10-36] days vs 20 [10-48] days; P = .42) did not differ between the daily interruption and control groups, respectively. Daily interruption was associated with higher mean daily doses of midazolam (102 mg/d vs 82 mg/d; P = .04) and fentanyl (median [IQR], 550 [50-1850] vs 260 [0-1400]; P < .001) and more daily boluses of benzodiazepines (mean, 0.253 vs 0.177; P = .007) and opiates (mean, 2.18 vs 1.79; P < .001). Unintentional endotracheal tube removal occurred in 10 of 214 (4.7%) vs 12 of 207 patients (5.8%) in the interruption and control groups, respectively (relative risk, 0.82; 95% CI, 0.36-1.84; P = .64). Rates of delirium were not significantly different between groups (53.3% vs 54.1%; relative risk, 0.98; 95% CI, 0.82-1.17; P = .83). Nurse workload was greater in the interruption group (VAS score, 4.22 vs 3.80; mean difference, 0.41; 95% CI, 0.17-0.66; P = .001). CONCLUSION: For mechanically ventilated adults managed with protocolized sedation, the addition of daily sedation interruption did not reduce the duration of mechanical ventilation or ICU stay.

BACKGROUND: Safe, effective, and easily implementable treatments that reduce the progression of respiratory failure in COVID-19 are urgently needed. Despite the increased adoption of prone positioning during the pandemic, the effectiveness of this technique on progression of respiratory failure among nonintubated patients is unclear. RESEARCH QUESTION: What is the effectiveness of smartphone-guided self-prone positioning recommendations and instructions compared with usual care in reducing progression of respiratory failure among nonintubated patients with COVID-19? STUDY DESIGN AND METHODS: Awake Prone Position for Early Hypoxemia in COVID-19 (APPEX-19) is a multicenter randomized clinical trial that randomized nonintubated adults with COVID-19 on < 6 L/min of supplemental oxygen to receive a smartphone-guided self-prone positioning intervention or usual care. The primary outcome was the composite of respiratory deterioration (an increase in supplemental oxygen requirement) or ICU transfer. Using a Bayesian statistical approach, the posterior probability of superiority within each treatment arm (superiority threshold 95%) was calculated. RESULTS: The trial was stopped early for slow enrollment. A total of 293 participants were included in the modified intention-to-treat analysis (159 self-prone positioning intervention and 134 usual care). Among participants who self-reported body positioning (n = 139 [70 intervention, 69 usual care]), 71.4% in the intervention arm and 59.4% in the usual care arm attempted prone positioning. Thirty-one participants (posterior mean, 24.7%; 95% credible interval, 18.6-31.4) receiving usual care and 32 participants (posterior mean, 22.1%; 95% credible interval, 16.6-28.1) receiving the self-prone positioning intervention experienced the primary outcome; the posterior probability of superiority for the self-prone positioning intervention was 72.1%, less than the 95% threshold for superiority. Adverse events occurred in 26.9% of participants in the usual care arm and in 11.9% of participants in the intervention arm. INTERPRETATION: Among nonintubated patients with COVID-19, smartphone-guided self-prone positioning recommendations and instructions did not promote strong adherence to prone positioning.

The surge in clinical demand, shortage in personal protective equipment and high-exposure risk for healthcare workers during the COVID-19 pandemic has challenged hospital common practices and forced a reassessment of care delivery models. Code blue teams are highly specialised units that partake in life-saving situations that can jeopardise the safety of team members. There is a paucity of guidance in regards to proper infection control measures to protect the responders.This study describes a methodical approach to assessing vulnerabilities to transmission of SARS-CoV-2 within existing code blue practices, modalities to limit the number of code blue team responders and modifications to the protocol at a large community teaching hospital. The effort undertaken faced challenges due to the nature of the pandemic and the increased demand on healthcare workers. Quality improvement methods facilitated our protocol design and implementation. To this date, there has been no identified COVID-19 disease in any protected code blue (PCB) team members. We recommend that similar practices be considered and adopted widely and practised periodically.

BACKGROUND: Unplanned extubation represents a threat to patient safety, and risk factors and prevention strategies for unplanned extubation have not been fully explored. OBJECTIVES: To define high-risk patients for unplanned extubation and determine clinicians' beliefs on perceived risks for unplanned extubation METHODS: With a Web-based survey instrument we surveyed critical care clinician members of the American Association for Respiratory Care, the American Association of Critical Care Nurses, and the Society of Critical Care Medicine. RESULTS: Surveys were completed by 1,976 clinicians, including 419 respiratory therapists, 870 critical care nurses, and 605 critical care physicians. The majority of respondents considered an outward migration of the endotracheal tube (by 3 cm, 2 cm if an air leak is present) to represent a risk for unplanned extubation. Respondents considered the following as high risk for unplanned extubation: absence of physical restraints (72% of respondents), a nurse/patient ratio of 1/3 (60%), trips out of the intensive care unit (59%), light sedation (43%), and bedside portable radiograph (29%). In addition, most respondents considered accidental removal of the nasogastric tube (71%) or tugging on the endotracheal tube (87%) by the patient to be risk factors for unplanned extubation. The rank order of the perceived risks was related to the respondents' primary discipline. CONCLUSIONS: We identified perceived risk factors and defined "near misses" for unplanned extubation. Our findings should inform strategies for prevention of unplanned extubation.

PURPOSE: To determine the feasibility of conducting a multicenter ICU RCT of AFS compared to either protocol-directed sedation (PDS) or both PDS and daily sedation interruption (DSI) in North America. MATERIALS AND METHODS: This single-center RCT compared AFS [fentanyl (bolus ± infusions) to reach CPOT ≤2; if RASS ≥1, CPOT ≤2 and additional fentanyl failed to reach RASS goal (-2 to 0), low-dose propofol (up to 6â¯h) was given] with either PDS or both PDS and DSI daily in adults mechanically ventilated (MV) ≥48â¯h. Relevant feasibility, safety, and clinical outcomes were defined and evaluated. RESULTS: 90 of 160 eligible patients were enrolled [AFSâ¯=â¯27; PDSâ¯=â¯28; PDSâ¯+â¯DSIâ¯=â¯31]; rateâ¯=â¯3/month. Time from intubation to randomization was 17.5⯱â¯11.6â¯h. Study days fully adherent to the study intervention [AFSâ¯=â¯95%; PDSâ¯=â¯99%; PDSâ¯+â¯DSIâ¯=â¯96%] and time spent in the first 48â¯h after randomization without pain (CPOT ≤2)[AFSâ¯=â¯82%; PDSâ¯=â¯78%; PDSâ¯+â¯DSIâ¯=â¯77%] and at goal RASS[AFSâ¯=â¯88%; PDSâ¯=â¯83%; PDSâ¯+â¯DSIâ¯=â¯95%] were high and similar. Nurse-perceived [median (IQR)] study workload (10-point VAS) was higher with AFS [4(2-6)] than PDS [1(1-3)] or PDSâ¯+â¯DSI [2(1-5)]; pâ¯=â¯.002). Unplanned extubation was rare (AFSâ¯=â¯1; PDS =â¯0; PDSâ¯+â¯DSIâ¯=â¯1). Days [median (IQR)] free of MV in the 28d after intubation [AFS 24(23,26); PDS 24(20,26); PDSâ¯+â¯DSI 24(21,26)] was not different (pâ¯=â¯.62). CONCLUSION: A multicenter RCT evaluating AFS is feasible to conduct in North America.

RATIONALE: In critically ill patients receiving invasive mechanical ventilation (MV), research supports the use of daily screening to identify patients who are ready to undergo a spontaneous breathing trial (SBT) followed by conduct of an SBT. However, once daily (OD) screening is poorly aligned with the continuous care provided in most intensive care units (ICUs) and the best SBT technique for clinicians to use remains controversial. OBJECTIVES: To identify the optimal screening frequency and SBT technique to wean critically ill adults in the ICU. METHODS: We aim to conduct a multicenter, factorial design randomized controlled trial with concealed allocation, comparing the effect of both screening frequency (once versus at least twice daily [ALTD]) and SBT technique (Pressure Support [PS] + Positive End-Expiratory Pressure [PEEP] vs T-piece) on the time to successful extubation (primary outcome) in 760 critically ill adults who are invasively ventilated for at least 24 h in 20 North American ICUs. In the OD arm, respiratory therapists (RTs) will screen study patients between 06:00 and 08:00 h. In the ALTD arm, patients will be screened at least twice daily between 06:00 and 08:00 h and between 13:00 and 15:00 h with additional screens permitted at the clinician's discretion. When the SBT screen is passed, an SBT will be conducted using the assigned technique (PS + PEEP or T-piece). We will follow patients until successful extubation, death, ICU discharge, or until day 60 after randomization. We will contact patients or their surrogates six months after randomization to assess health-related quality of life and functional status. RELEVANCE: The around-the-clock availability of RTs in North American ICUs presents an important opportunity to identify the optimal SBT screening frequency and SBT technique to minimize patients' exposure to invasive ventilation and ventilator-related complications.

Neurofibromatosis type 1 (NF1)-related lung disease is a rare but increasingly recognised, high morbidity associated feature of the condition. We present a 48-year-old male patient with NF1, who was initially admitted for a subarachnoid haemorrhage requiring aneurysmal coil embolisation. During his recovery, he developed a left-sided pneumothorax requiring chest tube placement followed by concerns for re-expansion pulmonary oedema requiring intubation. Subsequently, the patient also developed a right-sided pneumothorax requiring additional chest tube placement but did not develop right-sided pulmonary oedema. During his hospitalisation, the patient also exemplified other important NF1-related pathophysiology including pheochromocytoma, cerebrovascular abnormalities and cardiovascular manifestations. Due to his multiple comorbidities and poor prognosis, we held a goals of care discussion with the patient's mother, and with her agreement, the patient underwent compassionate withdrawal of artificial life support.

Nodular lung disease is a rare pulmonary manifestation of sarcoidosis and resembles metastatic neoplasm disease. Nodular sarcoidosis is rare, varying from 1.6% to 4% of patients with sarcoidosis. Radiographic nodules measure from 1 to 5 cm in diameter that typically consist of coalescent granulomas. There is limited data on this form of sarcoidosis and its presentation can mimic primary or metastatic pulmonary neoplasms. Nodular sarcoidosis has a favorable prognosis, and resolution can be seen with oral corticosteroids. Herein, we present such a case of nodular pulmonary sarcoidosis with a lung nodule measured up to 6 cm.
RESUMEN
BACKGROUND: Hand hygiene compliance remains low, despite its effectiveness in preventing infections. Gowns are routinely used to reduce dissemination of organisms within hospitals. Use of gowns is time consuming and costly, and their effectiveness, compared with that of hand hygiene alone, is debated. Among the arguments supporting a gown-use requirement is the potential to boost awareness of infection control, leading to improved hand hygiene compliance. METHODS: Hand hygiene compliance was recorded in a 14-month crossover trial comparing compliance at 2 intensive care units during periods with and without a gown-use requirement. RESULTS: During 170 h of observation, 1619 hand hygiene opportunities were recorded. Compliance was 10% before care was given and 36% after care was given. Compliance with glove and gown use was 62% and 63%, respectively. After-care hand hygiene compliance for nurses, physicians, and therapists was 40%, 38%, and 22%, respectively. Compliance after patient contact, body fluid contact, and other in-room activity was 42%, 48%, and 22%, respectively. For periods with and without a gown-use requirement, overall after-care compliance (37% vs. 34%) and rates by personnel and activity type were similar. In the subgroup of patients on contact precautions, hand hygiene compliance during the period with a gown-use requirement versus the period without a gown-use requirement was 11% versus 10% (P=.85) before care was given and 45% versus 39% (P=.09) after care was given. In this subgroup, after adjustment for type of in-room activity, medical personnel, intensive care unit, and observer, the predicted after-care hand hygiene compliance during periods with and without a gown-use requirement was 48% versus 41% (P=.02). CONCLUSIONS: The hypothesis that a gown-use requirement might improve hand hygiene compliance in the intensive care unit could not be confirmed. In the subgroup of patients on contact precautions, improvement in hand hygiene compliance associated with the gown-use requirement was small and did not affect precare rates.

BACKGROUND: Cardiac dysfunction is one of many causes for unsuccessful weaning from mechanical ventilation. Although cardiac dysfunction can be detected via direct measurement of cardiac output during weaning, available methods are not feasible. OBJECTIVE: To investigate the role of noninvasive monitoring of cardiac output during weaning and determine if a relationship exists between serial measurements during the spontaneous breathing trial and weaning outcomes. METHODS: A prospective, observational study was conducted in the intensive care unit at a university-affiliated teaching hospital. The sample consisted of patients intubated for more than 24 hours who were being weaned off of mechanical ventilation according to a validated weaning protocol. Before the first spontaneous breathing trial, a noninvasive cardiac output monitor was connected to the ventilator circuit. Measurements were made before, at the beginning of, and at the end of the trial. RESULTS: Among the 85 patients tested, baseline cardiac output was similar (P = .93) for those in whom the first trial was successful (mean [SD], 5.7 [2.1] L/min) and those in whom the trial was unsuccessful (5.6 [1.8] L/ min). Unlike patients with unsuccessful trials, patients with successful trials were able to augment their cardiac output from baseline. Mean cardiac output increased to 7.1 (SD, 3.1) L/min for patients in whom weaning was successful and to 6.2 (SD, 2.3) L/min for those in whom weaning was unsuccessful (P = .001). CONCLUSION: A noninvasive method of monitoring cardiac output can be easily applied while patients are being weaned off of mechanical ventilation.
