RESUMO

BACKGROUND: The effect of a liberal transfusion strategy as compared with a restrictive strategy on outcomes in critically ill patients with traumatic brain injury is unclear. METHODS: We randomly assigned adults with moderate or severe traumatic brain injury and anemia to receive transfusion of red cells according to a liberal strategy (transfusions initiated at a hemoglobin level of ≤10 g per deciliter) or a restrictive strategy (transfusions initiated at ≤7 g per deciliter). The primary outcome was an unfavorable outcome as assessed by the score on the Glasgow Outcome Scale-Extended at 6 months, which we categorized with the use of a sliding dichotomy that was based on the prognosis of each patient at baseline. Secondary outcomes included mortality, functional independence, quality of life, and depression at 6 months. RESULTS: A total of 742 patients underwent randomization, with 371 assigned to each group. The analysis of the primary outcome included 722 patients. The median hemoglobin level in the intensive care unit was 10.8 g per deciliter in the group assigned to the liberal strategy and 8.8 g per deciliter in the group assigned to the restrictive strategy. An unfavorable outcome occurred in 249 of 364 patients (68.4%) in the liberal-strategy group and in 263 of 358 (73.5%) in the restrictive-strategy group (adjusted absolute difference, restrictive strategy vs. liberal strategy, 5.4 percentage points; 95% confidence interval, -2.9 to 13.7). Among survivors, a liberal strategy was associated with higher scores on some but not all the scales assessing functional independence and quality of life. No association was observed between the transfusion strategy and mortality or depression. Venous thromboembolic events occurred in 8.4% of the patients in each group, and acute respiratory distress syndrome occurred in 3.3% and 0.8% of patients in the liberal-strategy and restrictive-strategy groups, respectively. CONCLUSIONS: In critically ill patients with traumatic brain injury and anemia, a liberal transfusion strategy did not reduce the risk of an unfavorable neurologic outcome at 6 months.

RESUMO

To determine the number of patients with acute respiratory distress syndrome (ARDS) who would be eligible to receive veno-venous extracorporeal membrane oxygenation (VV-ECMO). We conducted a retrospective observational study of ARDS patients admitted to Regina General Hospital Intensive Care Unit (ICU). VV-ECMO eligibility was assessed using selection criteria from the Extracorporeal Membrane Oxygenation for Severe Acute Respiratory Syndrome trial (EOLIA), the Extracorporeal Life Support Organization (ELSO), New South Wales (NSW), Critical Care Services Ontario (CCSO) and a Regina-restrictive criteria. Of 415 patients admitted between October 16, 2018, and January 21, 2021, 103 (25%) had mild, 175 (42%) had moderate, and 64 (15%) had severe ARDS. Of the cohort, 144 (35%) had bacterial pneumonia, 86 (21%) had viral pneumonia (including COVID-19), and 72 (17%) had aspiration pneumonia. Using the EOLIA, ELSO, NSW, CCSO and Regina-restrictive criteria, 7/415 (1.7%), 6/415 (1.5%), 19/415 (4.6%), 26/415 (6.3%) and 12/415 (2.9%) were eligible for VV-ECMO, respectively. Of all ECMO-eligible patients, only one (2.4%) actually received VV-ECMO, 20/42 (48%) received prone positioning and 21/42 (50%) received neuromuscular blockade. There is potential for service expansion of VV-ECMO in Regina; however, there is still a need to improve the delivery of evidence-based ARDS therapies.

RESUMO

Background: Among critically ill patients receiving mechanical ventilation, Candida spp. are commonly detected in the lower respiratory tract (LRT). This is generally considered to represent colonization. Objective: To evaluate the use of antifungal treatments and the clinical outcomes of patients with Candida colonization of the LRT. Methods: This retrospective analysis involved consecutive patients admitted to the intensive care unit between April 2016 and May 2021with positive results on Candida spp. testing of LRT samples. Data related to antifungal treatment and clinical outcomes were analyzed descriptively, and multivariable logistic regression was performed. Results: Of 200 patients initially identified, 160 (80%) died in hospital. Antifungal therapy was given to 103 (51.5%) of the patients, with treatment being more likely among those with shock and those who received parenteral nutrition. Mortality was high among patients with positive Candida results on LRT culture, regardless of treatment. Multivariable logistic regression, with adjustment for age, sex, comorbidities, and sequential organ failure assessment (SOFA) score, showed that antifungal treatment was associated with lower odds of death (odds ratio 0.39, 95% confidence interval 0.17-0.87) compared with no treatment (p = 0.021). Conclusions: This study showed higher mortality rates than have been reported previously. Further investigation into the role of antifungal therapy among critically ill patients with Candida spp. colonization is required.


Contexte: Chez les patients gravement malades recevant une ventilation mécanique, les Candida spp. sont fréquemment détectées dans les voies respiratoires inférieures (VRI) ­ une situation généralement considérée comme une colonisation. Objectif: Évaluer l'utilisation d'un traitement antifongique et les résultats cliniques chez les patients présentant une colonisation par Candida dans les VRI. Méthodes: Cette analyse rétrospective portait sur des patients consécutifs de l'unité de soins intensifs ayant obtenu un résultat positif au test de Candida sur les isolats des VRI entre avril 2016 et mai 2021. Les données relatives au traitement antifongique et aux résultats cliniques ont été analysées de manière descriptive, et une régression logistique multivariable a été effectuée. Résultats: Parmi les 200 patients initialement recensés, 160 (80 %) sont décédés à l'hôpital. Une thérapie antifongique a été administrée à 103 (51,5 %) des patients, et le traitement était plus probable chez ceux en état de choc et ceux ayant reçu une nutrition parentérale. Les patients ayant été déclarés positifs pour la Candida dans la culture des VRI présentaient un taux de mortalité élevé, indépendamment du traitement. Une régression logistique multivariable, avec ajustement pour l'âge, le sexe, les comorbidités et le score SOFA (sequential organ failure assessment), a montré que le traitement antifongique était associé à une probabilité de décès réduite (rapport de cotes 0,39; intervalle de confiance à 95 % 0,17­0,87), par rapport à l'absence de traitement (p = 0,021). Conclusions: Cette étude a révélé des taux de mortalité plus élevés que ce qui avait été rapporté précédemment. Une enquête plus approfondie sur le rôle de la thérapie antifongique chez les patients gravement malades présentant une colonisation par Candida spp. est nécessaire.

RESUMO

OBJECTIVES: Critically ill patients are increasingly being discharged directly home from PICU as opposed to discharged home, via the ward. The objective was to assess the prevalence, safety, and satisfaction of discharge directly home from PICUs. DATA SOURCES: We searched PubMed, Medline, EMBASE, PsycINFO, and CINAHL for studies published between January 1991 and June 2021. STUDY SELECTION: We included observational or randomized studies, of children up to 18 years old, that reported on the prevalence, safety, or satisfaction of discharge directly home from the PICU, compared with the ward. Safety outcomes included readmission, unplanned visits to hospital, and any adverse events. We excluded case series, reviews, and studies discharging patients to other facilities. DATA EXTRACTION: Two independent reviewers evaluated 88 full-text articles; five studies met eligibility (362,868 patients). Only one study had discharge directly home as a primary outcome. DATA SYNTHESIS: Prevalence of discharge directly to home from the PICU ranged from less than 1% to 23% (random effects proportion 7.7 [95% CI, 1.3-18.6]). Readmissions to the PICU (only safety outcome) were significantly lower in the discharge directly home group compared with the ward group, in two of three studies (p < 0.0001). No studies reported on patient or family satisfaction. CONCLUSIONS: The prevalence of discharge directly home from the PICU ranges from 1% to 23%. PICU readmission rates do not appear to increase after discharge directly home. Caution is needed in the interpretation of the results, given the significant heterogeneity of the included studies. Further high-quality studies are needed to evaluate the safety of discharge directly home from the PICU and support families in this transition.

RESUMO

OBJECTIVE: To evaluate the impact of direct discharge home (DDH) from ICUs compared with ward transfer on safety outcomes of readmissions, emergency department (ED) visits, and mortality. DATA SOURCES: We searched MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, and Cumulative Index to Nursing and Allied Health Literature from inception until March 28, 2022. STUDY SELECTION: Randomized and nonrandomized studies of DDH patients compared with ward transfer were eligible. DATA EXTRACTION: We screened and extracted studies independently and in duplicate. We assessed risk of bias using the Newcastle-Ottawa Scale for observational studies. A random-effects meta-analysis model and heterogeneity assessment was performed using pooled data (inverse variance) for propensity-matched and unadjusted cohorts. We assessed the overall certainty of evidence for each outcome using the Grading Recommendations Assessment, Development and Evaluation approach. DATA SYNTHESIS: Of 10,228 citations identified, we included six studies. Of these, three high-quality studies, which enrolled 49,376 patients in propensity-matched cohorts, could be pooled using meta-analysis. For DDH from ICU, compared with ward transfers, there was no difference in the risk of ED visits at 30-day (22.4% vs 22.7%; relative risk [RR], 0.99; 95% CI, 0.95-1.02; p = 0.39; low certainty); hospital readmissions at 30-day (9.8% vs 9.6%; RR, 1.02; 95% CI, 0.91-1.15; p = 0.71; very low-to-low certainty); or 90-day mortality (2.8% vs 2.6%; RR, 1.06; 95% CI, 0.95-1.18; p = 0.29; very low-to-low certainty). There were no important differences in the unmatched cohorts or across subgroup analyses. CONCLUSIONS: Very low-to-low certainty evidence from observational studies suggests that DDH from ICU may have no difference in safety outcomes compared with ward transfer of selected ICU patients. In the future, this research question could be further examined by randomized control trials to provide higher certainty data.

RESUMO

Neck swelling during venovenous extracorporeal membrane oxygenation (VV-ECMO) usually heralds the development of potentially serious complications, including superior vena cava (SVC) syndrome, hematoma, and/or angioedema. In this case report, we describe a 43-year-old male patient who had received VV-ECMO support for the coronavirus disease 2019 (COVID-19) acute respiratory distress syndrome. During his hospitalization, he developed acute onset of neck swelling after two weeks of VV-ECMO and two days after a tracheostomy. Clinical examination and investigations were performed to exclude ECMO-related SVC syndrome and tracheostomy-related complications. Consequently, it was discovered the patient had developed COVID-19-related subacute thyroiditis with enlargement of both thyroid glands. Conservative management, including the use of continued glucocorticoids, raising the head of the bed, and observing for complications of thyroiditis, was undertaken. Eventually, this patient's neck swelling resolved on its own, and he was eventually decannulated from ECMO several weeks later. Our case report highlights the differential diagnosis of neck swelling during VV-ECMO and considers the evaluation of different etiologies.

RESUMO

To externally validate the Hospital Frailty Risk Score (HFRS) in critically ill patients. We selected older adult (≥ 75 years old) hospitalizations receiving mechanical ventilation, using the Nationwide Readmissions Database (January 1, 2016-November 30, 2018). Frailty risk was subcategorized into low-risk (HFRS score < 5), intermediate-risk (score 5-15), and high-risk (score > 15). We evaluated the HFRS to predict in-hospital mortality, prolonged hospitalization, and 30-day readmissions, using multivariable logistic regression, adjusting for patient and hospital characteristics. Model performance was assessed using the c-statistic, Brier score, and calibration plots. Among 649,330 weighted hospitalizations, 9.5%, 68.3%, and 22.2% were subcategorized as low-, intermediate-, and high-risk for frailty, respectively. After adjustment, high-risk patient hospitalizations were associated with increased risks of prolonged hospitalization (adjusted odds ratio [aOR] 5.59 [95% confidence interval [CI] 5.24-5.97], c-statistic 0.694, Brier 0.216) and 30-day readmissions (aOR 1.20 [95% CI 1.13-1.27], c-statistic 0.595, Brier 0.162), compared to low-risk hospitalizations. Conversely, high-risk hospitalizations were inversely associated with in-hospital mortality (aOR 0.46 [95% CI 0.45-0.48], c-statistic 0.712, Brier 0.214). The HFRS was not successfully validated to predict in-hospital mortality in critically ill older adults. While it may predict other outcomes, its use should be avoided in the critically ill.

RESUMO

Although acute COVID-19 is known to cause cardiac damage in some cases, there is still much to learn about the duration and relative permanence of the damage that may occur. Long COVID is a condition that can occur when COVID-19 symptoms remain in the postviral acute period. Varying accounts of long COVID have been described across the literature, however, cardiac impairments are sustained in many individuals and cardiovascular assessment is now considered to be an expected follow-up examination. The purpose of this review and proof of concept is to summarize the current research related to the assessment of cardiac function, including echocardiography and blood biomarker data, during the follow-up period in patients who recovered from COVID-19. Following a literature review, it was found that right ventricular dysfunction along with global longitudinal strain and diastolic dysfunction are common findings. Finally, more severe acute myocardial injury during the index hospitalization appears to exacerbate cardiac function. The available literature implies that cardiac function must be monitored in patients recovered from COVID-19 who remain symptomatic and that the impairments and severity vary from person-to-person. The proof-of-concept analysis of patients with cardiac disease and respiratory disease in comparison to those with sustained symptoms from COVID-19 suggests elevated systolic time interval in those with sustained symptoms from COVID-19, thus reducing heart performance indices. Future research must consider the details of cardiac complications during the acute infection period and relate this to the cardiac function in patients with long COVID during mid- and long-term follow-up.

RESUMO

Purpose: Cirrhotic patients in organ failure are frequently admitted to intensive care units (ICUs) to receive invasive mechanical ventilation (IMV). We evaluated the trends of hospitalizations, in-hospital mortality, hospital costs, and hospital length of stay (LOS) of IMV patients with cirrhosis. Methods: We analyzed the United States National Inpatient Sample from 2005-2014. We selected discharges of IMV adult (≥18 years) patients with cirrhosis using the International Classification of Diseases, 9th Edition, Clinical Modification codes. Trends were assessed using linear regression and joinpoint regression. Results: Between 2005 and 2014, there were approximately 9,441,605 hospitalizations of IMV adult patients, of which 4.7% had cirrhosis. There was an increasing trend in the total number of IMV cirrhotic patient hospitalizations (annual percent change [APC] 7.0%, 95% confidence interval [CI] 6.4%; 7.6%, Ptrend < 0.001). The in-hospital case-fatality ratio declined between 2005-2011 (APC -2.9%, 95% CI, -3.4%; -2.4%, Ptrend < 0.001); however, it remained similar between 2011-2014 (Ptrend = 0.58). The total annual hospital costs of all IMV cirrhotic patients increased from approximately $1.2 billion USD in 2005 to $2.7 billion USD in 2014 (Ptrend < 0.001). The mean hospital costs per patient and mean LOS declined between 2005 and 2014 (Ptrend < 0.001 and Ptrend = 0.01 respectively). Conclusions: The total number of hospitalizations and total annual costs of IMV patients with cirrhosis have been increasing over time. However, past hesitancy around admitting cirrhotic patients to the ICU may need to be tempered by the improving mortality trends in this patient population.

RESUMO

Purpose: To evaluate the long-term safety of directly discharging intensive care unit (ICU) survivors to their home. Methods: A retrospective observational cohort of 341 ICU survivors who were directly discharged home from the ICU ("direct discharge") or discharged home ≤72 hours after ICU transfer to the ward ("ward transfer") was conducted in Regina, Saskatchewan ICUs between September 1, 2016 and September 30, 2018. The primary outcome was 90-day hospital readmission. Secondary outcomes included 30-day, 90-day, and 365-day emergency department (ED) visits, 30-day and 365-day hospital readmissions, and 365-day mortality. All outcomes were evaluated by multivariable Cox regression after adjustment for demographic and clinical characteristics. Results: Of 341 survivors (25.5% of total ICU visits), 148 (43.4%) patients were direct discharges and 193 (56.6%) were ward transfers. The median age was 46 years (interquartile range, 34-62), 38.4% were female, and 61.8% resided in Regina. Compared to the ward transfer cohort, more patients in the direct discharge cohort had at least one 90-day hospital readmission (30.4% versus 17.1% of patients, adjusted hazard ratio 2.09, 95% confidence interval 1.28-3.40, P = .003), after adjustment. Additionally, there were more 90-day ED visits (P = .045), and 30-day (P = .049) and 365-day hospital readmissions (P = .03), after adjustment. Conclusions: In Saskatchewan, direct discharge compared to ward transfer was associated with an increase in 90-day hospital readmissions, and potentially other clinical outcomes. Further study is necessary.

RESUMO

BACKGROUND: There is an increasing number of adults with congenital heart disease (ACHD), but critically ill patients with ACHD remain understudied. The objective of this study was to evaluate patient characteristics and trends in mortality of mechanically ventilated patients with ACHD. METHODS: We evaluated ACHD with an ICD-9 procedure code for mechanical ventilation using the National Inpatient Sample (NIS), a public all-payer inpatient United States database, from 2005 to 2014. Primary and secondary outcomes were evaluated using multivariable logistic regression. RESULTS: There were 10,962 of 77,334,704 discharges, representing 52,876 (0.6%) hospitalizations that were for patients with ACHD who required mechanical ventilation (MV). Mean age was 59 years (interquartile range: 45-71); 45.3% were female patients. The number of patients with ACHD requiring MV increased over the years (2342 to 7775, P < 0.001). Age and comorbidities of this cohort also increased (55 to 59, P < 0.001; 1 to 2, P < 0.001). Case-fatality ratio remained stable over the years (0.254 to 0.259, P = 0.42). Median cost of hospital stay was USD $49,583 and remained stable over the study period (P = 0.42), whereas total cost increased from $115 million to $564 million (P < 0.001). CONCLUSIONS: The number of mechanically ventilated ACHD has increased over the years. Remarkably, despite an increase in the age and comorbidity burden in this cohort, case-fatality ratio of these patients and the cost per patient remained stable. Nonetheless, there is a growing need for health care resources in the management of this cohort of patients. Further studies will need to be conducted to evaluate the underlying physiological impact and prognosis of MV in specific subsets of ACHD.


INTRODUCTION: Il existe un nombre croissant d'adultes atteints d'une cardiopathie congénitale (CC), mais peu d'études portent sur les patients gravement atteints d'une CC. L'objectif de la présente étude était l'évaluation des caractéristiques des patients et des tendances de la mortalité des patients atteints d'une CC sous ventilation mécanique. MÉTHODES: Nous avons évalué les patients atteints d'une CC sous ventilation mécanique (VM, code ICD-9) à l'aide de l'échantillon national des patients hospitalisés (NIS, National Inpatient Sample), une base de données sur les patients hospitalisés des États-Unis accessible au public, de 2005 à 2014. Nous avons évalué les critères de jugement principal et secondaire à l'aide de la régression logistique multivariée. RÉSULTATS: Les 10 962 sorties d'hôpital sur 77 334 704, soit 52 876 (0,6 %) hospitalisations, concernaient des patients atteints d'une CC qui avaient nécessité une VM. L'âge moyen était de 59 ans (écart interquartile : 45-71); 45,3 % étaient des femmes. Le nombre de patients atteints d'une CC qui avaient nécessité une VM augmentait au fil des années (de 2 342 à 7 775, P < 0,001). L'âge et les comorbidités de cette cohorte augmentaient aussi (de 55 à 59, P < 0,001; de 1 à 2, P < 0,001). Le taux de létalité restait stable au fil des années (de 0,254 à 0,259, P = 0,42). Le coût médian des séjours à l'hôpital était de 49 583 $ US et restait stable au cours de la période de l'étude (P = 0,42), alors que le coût total passait de 115 M$ à 564 M$ (P < 0,001). CONCLUSIONS: Le nombre de patients atteints d'une CC sous VM a augmenté au fil des années. Étonnamment, en dépit d'une augmentation de l'âge et du fardeau des comorbidités dans cette cohorte, le taux de létalité de ces patients et le coût par patient demeurait stable. Néanmoins, il existe un urgent besoin de ressources de soins de santé pour la prise en charge de cette cohorte de patients. Il sera nécessaire de mener d'autres études pour évaluer les effets physiologiques sous-jacents et le pronostic des patients sous VM dans des sous-ensembles spécifiques de CC.

RESUMO

PURPOSE: We evaluated the effects of after-hours/nighttime patient transfers out of the ICU on patient outcomes, by performing a systematic review and meta-analysis (PROSPERO CRD 42017074082). DATA SOURCES: MEDLINE, PubMed, EMBASE, Google Scholar, CINAHL, and the Cochrane Library from 1987-November 2019. Conference abstracts from the Society of Critical Care Medicine, American Thoracic Society, CHEST, Critical Care Canada Forum, and European Society of Intensive Care Medicine from 2011-2019. DATA EXTRACTION: Observational or randomized studies of adult ICU patients were selected if they compared after-hours transfer out of the ICU to daytime transfer on patient outcomes. Case reports, case series, letters, and reviews were excluded. Study year, country, design, co-variates for adjustment, definitions of after-hours, mortality rates, ICU readmission rates, and hospital length of stay (LOS) were extracted. DATA SYNTHESIS: We identified 3,398 studies. Thirty-one observational studies (1,418,924 patients) were selected for the systematic review and meta-analysis. Included studies had varying definitions of after-hours, with the after-hours period starting anytime between 16:00-22:00 and ending between 06:00-09:00. Approximately 16% of transfers occurred after-hours. After-hours transfers were associated with increased in-hospital mortality for both unadjusted (odds ratio [OR] 1.51, 95% confidence interval [CI] 1.30-1.75, I2 = 96%, number of studies [n] = 26, P < 0.001, low certainty) and adjusted (OR 1.32, 95% CI 1.25-1.38, I 2 = 33%, n = 10, P < 0.001, low certainty) data, compared to daytime transfers. They were also associated with increased ICU readmission (pooled unadjusted OR 1.28, 95% CI 1.18-1.38, I2 = 85%, n = 17, P < 0.001, low certainty) and longer hospital LOS (standardized mean difference 0.13, 95% CI 0.09-0.18, I 2 = 93%, n = 9, P < 0.001, low certainty), compared to daytime transfers. CONCLUSIONS: After-hours transfers out of the ICU are associated with increased in-hospital mortality, ICU readmission, and hospital LOS, across many settings. While the certainty of evidence is low, future research is needed to reduce the number and effects of after-hours transfers.

RESUMO

The spread of the novel coronavirus 2019 (COVID-19) has caused a global pandemic. The disease has spread rapidly, and research shows that COVID-19 can induce long-lasting cardiac damage. COVID-19 can result in elevated cardiac biomarkers indicative of acute cardiac injury, and research utilizing echocardiography has shown that there is mechanical dysfunction in these patients as well, especially when observing the isovolumic, systolic, and diastolic portions of the cardiac cycle. The purpose of this study was to present two case studies on COVID-19 positive patients who had their cardiac mechanical function assessed every day during the acute period to show that cardiac function in these patients was altered, and the damage occurring can change from day-to-day. Participant 1 showed compromised cardiac function in the systolic time, diastolic time, isovolumic time, and the calculated heart performance index (HPI), and these impairments were sustained even 23 days post-symptom onset. Furthermore, Participant 1 showed prolonged systolic periods that lasted longer than the diastolic periods, indicative of elevated pulmonary artery pressure. Participant 2 showed decreases in systole and consequently, increases in HPI during the 3 days post-symptom onset, and these changes returned to normal after day 4. These results showed that daily observation of cardiac function can provide detailed information about the overall mechanism by which cardiac dysfunction is occurring and that COVID-19 can induce cardiac damage in unique patterns and thus can be studied on a case-by-case basis, day-to-day during infection. This could allow us to move toward more personalized cardiovascular medical treatment.

OBJECTIVES: To evaluate the number of out-of-hospital cardiac arrest (OHCA) patients eligible for extracorporeal cardiopulmonary resuscitation (ECPR) in Saskatchewan and their clinical outcomes, including survival and neurological outcomes at discharge. ECPR eligibility was assessed, using clinical criteria from the University of British Columbia (UBC, Canada), University of Michigan (UM, United States), University of California (UC, United States) and a restrictive ECPR criteria. RESULTS: We performed a retrospective cohort study of 200 OHCA patients (August 1, 2017-May 31, 2019) in Regina, Saskatchewan. Sixty-one (30%) were female, the median age was 64 years (interquartile range [IQR], 52-78), the median CPR duration was 30 min (IQR 12-47), and 20% survived to discharge. Two (1%) patients received ECPR but did not meet any ECPR criteria. Nineteen (10%), thirty (15%), twenty-two (11%), and seven (4%) patients were ECPR-eligible, using the UBC, UM, UC, and restrictive criteria. However, none of these patients had received ECPR. Only two (11%), two (7%), two (9%), and one (14%) of these patient(s) survived to discharge, respectively. Neurological outcomes were unfavourable among all ECPR-eligible patients. Future study at our centre will be necessary on how to implement ECPR program to further improve these outcomes.

RESUMO

PURPOSE: Severe traumatic brain injury (TBI) is a major cause of morbidity and mortality in critically ill patients. Pre-hospital care and transportation time may impact their outcomes. METHODS: Using the British Columbia Trauma Registry, we included 2,860 adult (≥18 years) patients with severe TBI (abbreviated injury scale head score ≥4), who were admitted to an intensive care unit (ICU) in a centre with neurosurgical services from January 1, 2000 to March 31, 2013. We evaluated the impact of transportation time (time of injury to time of arrival at a neurosurgical trauma centre) on in-hospital mortality and discharge disposition, adjusting for age, sex, year of injury, injury severity score (ISS), revised trauma score at the scene, location of injury, socio-economic status and direct versus indirect transfer. RESULTS: Patients had a median age of 43 years (interquartile range [IQR] 26-59) and 676 (23.6%) were female. They had a median ISS of 33 (IQR 26-43). Median transportation time was 80 minutes (IQR 40-315). ICU and hospital length of stay were 6 days (IQR 2-12) and 20 days (IQR 7-42), respectively. Six hundred and ninety-six (24.3%) patients died in hospital. After adjustment, there was no significant impact of transportation time on in-hospital mortality (odds ratio 0.98, 95% confidence interval 0.95-1.01). There was also no significant effect on discharge disposition. CONCLUSIONS: No association was found between pre-hospital transportation time and in-hospital mortality in critically ill patients with severe TBI.

RESUMO

OBJECTIVE: Postpneumonectomy patients may develop acute respiratory distress syndrome (ARDS). There is a paucity of data regarding the optimal management of mechanical ventilation for postpneumonectomy patients. Esophageal balloon pressure monitoring has been used in traditional ARDS patients to set positive end-expiratory pressure (PEEP) and minimize transpulmonary driving pressure (ΔP L), but its clinical use has not been previously described nor validated in postpneumonectomy patients. The primary objective of this report was to describe the potential clinical application of esophageal pressure monitoring to manage the postpneumonectomy patient with ARDS. DESIGN: Case report. Setting. Surgical intensive care unit (ICU) of a university-affiliated teaching hospital. Patient. A 28-year-old patient was involved in a motor vehicle collision, with a right main bronchus injury, that required a right-sided pneumonectomy to stabilize his condition. In the perioperative phase, they subsequently developed ventilator-associated pneumonia, significant cumulative positive fluid balance, and ARDS. Interventions. Prone positioning and neuromuscular blockade were initiated. An esophageal balloon was inserted to direct ventilator management. Measurements and Main Results. V T was kept around 3.6 mL/kg PBW, ΔP L at ≤14 cm H2O, and plateau pressure at ≤30 cm H2O. Lung compliance was measured to be 37 mL/cm H2O. PEEP was optimized to maintain end-inspiratory transpulmonary pressure (P L) < 15 cm H2O, and end-expiratory P L between 0 and 5 cm H2O. The maximal ΔP L was measured to be 11 cm H2O during the care of this patient. The patient improved with esophageal balloon-directed ventilator management and was eventually liberated from mechanical ventilation. CONCLUSIONS: The optimal targets for V T remain unknown in the postpneumonectomy patient. However, postpneumonectomy patients with ARDS may potentially benefit from very low V T and optimization of PEEP. We demonstrate the application of esophageal balloon pressure monitoring that clinicians could potentially use to limit injurious ventilation and improve outcomes in postpneumonectomy patients with ARDS. However, esophageal balloon pressure monitoring has not been extensively validated in this patient population.

RESUMO

High volume plasmapheresis (HVP) is defined as an exchange of 8-12 L or 15% of ideal body weight with fresh-frozen plasma. It has been reported that HVP can improve outcomes in patients with acute liver failure (ALF) and/or acute-on-chronic liver failure (ACLF). Here, we present a case of a 34-year-old man presenting with ALF that led to multi-organ failure who received HVP in the intensive care unit that improved his biochemical parameters, volume status, and hemodynamics. However, despite objective clinical and biochemical improvements, the patient had developed signs of potential brain injury, and subsequently the family withdrew care. This case and the associated literature review highlight the potential value of HVP in facilities who do not have access to liver transplantation or other means of extracorporeal liver support systems.
