RESUMO
BACKGROUND: Among critically ill adults undergoing tracheal intubation, hypoxemia increases the risk of cardiac arrest and death. The effect of preoxygenation with noninvasive ventilation, as compared with preoxygenation with an oxygen mask, on the incidence of hypoxemia during tracheal intubation is uncertain. METHODS: In a multicenter, randomized trial conducted at 24 emergency departments and intensive care units in the United States, we randomly assigned critically ill adults (age, ≥18 years) undergoing tracheal intubation to receive preoxygenation with either noninvasive ventilation or an oxygen mask. The primary outcome was hypoxemia during intubation, defined by an oxygen saturation of less than 85% during the interval between induction of anesthesia and 2 minutes after tracheal intubation. RESULTS: Among the 1301 patients enrolled, hypoxemia occurred in 57 of 624 patients (9.1%) in the noninvasive-ventilation group and in 118 of 637 patients (18.5%) in the oxygen-mask group (difference, -9.4 percentage points; 95% confidence interval [CI], -13.2 to -5.6; P<0.001). Cardiac arrest occurred in 1 patient (0.2%) in the noninvasive-ventilation group and in 7 patients (1.1%) in the oxygen-mask group (difference, -0.9 percentage points; 95% CI, -1.8 to -0.1). Aspiration occurred in 6 patients (0.9%) in the noninvasive-ventilation group and in 9 patients (1.4%) in the oxygen-mask group (difference, -0.4 percentage points; 95% CI, -1.6 to 0.7). CONCLUSIONS: Among critically ill adults undergoing tracheal intubation, preoxygenation with noninvasive ventilation resulted in a lower incidence of hypoxemia during intubation than preoxygenation with an oxygen mask.

BACKGROUND: Whether video laryngoscopy as compared with direct laryngoscopy increases the likelihood of successful tracheal intubation on the first attempt among critically ill adults is uncertain. METHODS: In a multicenter, randomized trial conducted at 17 emergency departments and intensive care units (ICUs), we randomly assigned critically ill adults undergoing tracheal intubation to the video-laryngoscope group or the direct-laryngoscope group. The primary outcome was successful intubation on the first attempt. The secondary outcome was the occurrence of severe complications during intubation; severe complications were defined as severe hypoxemia, severe hypotension, new or increased vasopressor use, cardiac arrest, or death. RESULTS: The trial was stopped for efficacy at the time of the single preplanned interim analysis. Among 1417 patients who were included in the final analysis (91.5% of whom underwent intubation that was performed by an emergency medicine resident or a critical care fellow), successful intubation on the first attempt occurred in 600 of the 705 patients (85.1%) in the video-laryngoscope group and in 504 of the 712 patients (70.8%) in the direct-laryngoscope group (absolute risk difference, 14.3 percentage points; 95% confidence interval [CI], 9.9 to 18.7; P<0.001). A total of 151 patients (21.4%) in the video-laryngoscope group and 149 patients (20.9%) in the direct-laryngoscope group had a severe complication during intubation (absolute risk difference, 0.5 percentage points; 95% CI, -3.9 to 4.9). Safety outcomes, including esophageal intubation, injury to the teeth, and aspiration, were similar in the two groups. CONCLUSIONS: Among critically ill adults undergoing tracheal intubation in an emergency department or ICU, the use of a video laryngoscope resulted in a higher incidence of successful intubation on the first attempt than the use of a direct laryngoscope.

BACKGROUND: Evidence for vaccine effectiveness (VE) against influenza-associated pneumonia has varied by season, location, and strain. We estimate VE against hospitalization for radiographically identified influenza-associated pneumonia during 2015-2016 to 2017-2018 seasons in the US Hospitalized Adult Influenza Vaccine Effectiveness Network (HAIVEN). METHODS: Among adults aged ≥18 years admitted to 10 US hospitals for acute respiratory illness (ARI), clinician-investigators used keywords from reports of chest imaging performed during 3 days around hospital admission to assign a diagnosis of "definite/probable pneumonia." We used a test-negative design to estimate VE against hospitalization for radiographically identified laboratory-confirmed influenza-associated pneumonia, comparing reverse transcriptase-polymerase chain reaction-confirmed influenza cases with test-negative subjects. Influenza vaccination status was documented in immunization records or self-reported, including date and location. Multivariable logistic regression models were used to adjust for age, site, season, calendar-time, and other factors. RESULTS: Of 4843 adults hospitalized with ARI included in the primary analysis, 266 (5.5%) had "definite/probable pneumonia" and confirmed influenza. Adjusted VE against hospitalization for any radiographically confirmed influenza-associated pneumonia was 38% (95% confidence interval [CI], 17-53%); by type/subtype, it was 74% (95% CI, 52-87%) influenza A (H1N1)pdm09, 25% (95% CI, -15% to 50%) A (H3N2), and 23% (95% CI, -32% to 54%) influenza B. Adjusted VE against intensive care for any influenza was 57% (95% CI, 19-77%). CONCLUSIONS: Influenza vaccination was modestly effective among adults in preventing hospitalizations and the need for intensive care associated with influenza pneumonia. VE was significantly higher against A (H1N1)pdm09 and was low against A (H3N2) and B.

Importance: Hypotension is common during tracheal intubation of critically ill adults and increases the risk of cardiac arrest and death. Whether administering an intravenous fluid bolus to critically ill adults undergoing tracheal intubation prevents severe hypotension, cardiac arrest, or death remains uncertain. Objective: To determine the effect of fluid bolus administration on the incidence of severe hypotension, cardiac arrest, and death. Design, Setting, and Participants: This randomized clinical trial enrolled 1067 critically ill adults undergoing tracheal intubation with sedation and positive pressure ventilation at 11 intensive care units in the US between February 1, 2019, and May 24, 2021. The date of final follow-up was June 21, 2021. Interventions: Patients were randomly assigned to receive either a 500-mL intravenous fluid bolus (n = 538) or no fluid bolus (n = 527). Main Outcomes and Measures: The primary outcome was cardiovascular collapse (defined as new or increased receipt of vasopressors or a systolic blood pressure <65 mm Hg between induction of anesthesia and 2 minutes after tracheal intubation, or cardiac arrest or death between induction of anesthesia and 1 hour after tracheal intubation). The secondary outcome was the incidence of death prior to day 28, which was censored at hospital discharge. Results: Among 1067 patients randomized, 1065 (99.8%) completed the trial and were included in the primary analysis (median age, 62 years [IQR, 51-70 years]; 42.1% were women). Cardiovascular collapse occurred in 113 patients (21.0%) in the fluid bolus group and in 96 patients (18.2%) in the no fluid bolus group (absolute difference, 2.8% [95% CI, -2.2% to 7.7%]; P = .25). New or increased receipt of vasopressors occurred in 20.6% of patients in the fluid bolus group compared with 17.6% of patients in the no fluid bolus group, a systolic blood pressure of less than 65 mm Hg occurred in 3.9% vs 4.2%, respectively, cardiac arrest occurred in 1.7% vs 1.5%, and death occurred in 0.7% vs 0.6%. Death prior to day 28 (censored at hospital discharge) occurred in 218 patients (40.5%) in the fluid bolus group compared with 223 patients (42.3%) in the no fluid bolus group (absolute difference, -1.8% [95% CI, -7.9% to 4.3%]; P = .55). Conclusions and Relevance: Among critically ill adults undergoing tracheal intubation, administration of an intravenous fluid bolus compared with no fluid bolus did not significantly decrease the incidence of cardiovascular collapse.

Duty-hours policies continue to be debated. Most know the pro and con arguments, but many may not be aware of background information preceding and intertwining the development and implementation of these policies. Interestingly, several aspects of law were involved or potentially correlated with policies enacted. This review updates new generations of physicians and scholars on the historical trajectory of duty-hour policies and highlights policy implications and the current state of evidence. In reviewing the historical and legal trajectory of duty-hours, many updates seemed to be a reaction to potential federal entanglement. Additionally, the review of the postimplementation literature revealed minimal empirical evidence. Instead, the majority of the positive findings were perception based. These summaries demonstrate a need for further outcomes evidence to validate policies.

INTRODUCTION: Severe acute respiratory distress syndrome (ARDS) has a high mortality, and there is limited knowledge about management of severe ARDS refractory to standard therapy. Early evidence suggests that therapeutic hypothermia (TH) could be a viable treatment for acute respiratory failure. We present 2 cases where TH was successfully used to manage refractory ARDS on extracorporeal membrane oxygenation (ECMO) and a review of the literature around TH and acute respiratory failure. RESULTS: We present 2 cases of ARDS secondary to H1N1 influenza and human metapneumovirus. Both patients were treated with the current evidence-based therapy for ARDS. Venovenous ECMO was used in both patients for refractory hypoxemia. Therapeutic hypothermia was applied for 24 hours with improved oxygenation. We did a review of the literature summarizing 38 patients in 10 publications where TH was successfully utilized in the treatment of acute respiratory failure. CONCLUSION: Therapeutic hypothermia may be a viable salvage therapy for ARDS refractory to the current evidence-based therapy but needs further evaluation.

Background: Intracerebral hemorrhage (ICH) is associated with high morbidity and mortality. ICH causes increased intracranial pressure (ICP), leading to brain herniation as the disease progresses. Neurological physical exam and monitoring of the disease progression can be challenging due to the impaired consciousness and routine clinical management in this patient population. Given the continuity of the intracranial cavity with the optic nerve subarachnoid space, an increased ICH leads to distension of the optic nerve sheath. We herein examined the correlation between the ICH volume and the optic nerve sheath diameter (ONSD) measured by point of care ultrasound (POCUS). Methods: Patients with ICH diagnosed with a head computed tomography (CT) scan were prospectively enrolled in this study. A portable ultrasound was used to measure the (ONSD); the volume of ICH hematoma, the Acute Physiology And Chronic Health Evaluation IV score, and the Intracerebral Hemorrhage score were collected. A Spearman rank correlation coefficient test was used to assess the relationship between continuous variables. A Wilcoxon rank sum test was used to assess differences in continuous variables between two groups. A p-value less than 0.05 was deemed as statistically significant. Results: A total of 28 subjects were enrolled. A moderate positive correlation was detected between hemorrhage volume and the average ONSD (correlation = 0.4214, p = 0.0255). A weak positive correlation was detected between average ONSD and APACHE IV (correlation = 0.2347, p = 0.2294). A weak moderate positive correlation was detected between average ONSD and ICH score (correlation = 0.1160, p = 0.5566). Conclusions: In this study we demonstrate that ONSD is moderately correlated with hematoma size. A potential application may include serial measurements of the ONSD with ultrasound. This may offer a quick, non-invasive technique that can be used in an intracerebral hemorrhage to monitor the stability or expansion of a hematoma indirectly, and potentially catch a catastrophic event like cerebral herniation.
RESUMO
BACKGROUND: Many COVID-19 studies are constructed to report hospitalization outcomes, with few large multi-center population-based reports on the time course of intra-hospitalization characteristics, including daily oxygenation support requirements. Comprehensive epidemiologic profiles of oxygenation methods used by day and by week during hospitalization across all severities are important to illustrate the clinical and economic burden of COVID-19 hospitalizations. METHODS: This was a retrospective, multi-center observational cohort study of 15,361 consecutive hospitalizations of patients with COVID-19 at 25 adult acute care hospitals in Texas participating in the Society of Critical Care Medicine Discovery Viral Respiratory Illness Universal Study COVID-19 registry. RESULTS: At initial hospitalization, the majority required nasal cannula (44.0%), with an increasing proportion of invasive mechanical ventilation in the first week and particularly the weeks to follow. After 4 weeks of acute illness, 69.9% of adults hospitalized with COVID-19 required intermediate (eg, high-flow nasal cannula, noninvasive ventilation) or advanced respiratory support (ie, invasive mechanical ventilation), with similar proportions that extended to hospitalizations that lasted ≥ 6 weeks. CONCLUSIONS: Data representation of intra-hospital processes of care drawn from hospitals with varied size, teaching and trauma designations is important to presenting a balanced perspective of care delivery mechanisms employed, such as daily oxygen method utilization.

Background: The RAPID [Renal (urea), Age, fluid Purulence, Infection source, Dietary (albumin)] score is a validated scoring system which allows risk stratification in patients with pleural infection at presentation. Surgical intervention plays a key role in managing pleural empyema. Methods: A retrospective study of patients with complicated pleural effusions and/or empyema undergoing thoracoscopic or open decortication admitted to multiple affiliated Texas hospitals from September 1, 2014 to September 30, 2018. The primary outcome was all-cause 90-day mortality. The secondary outcomes were organ failure, length of stay and 30-day readmission rate. The outcomes were compared between early surgery (≤3 days from diagnosis) and late surgery (>3 days from diagnosis) and low [0-3] vs. high [4-7] RAPID scores. Results: We enrolled 182 patients. Late surgery was associated with increased organ failure (64.0% vs. 45.6%, P=0.0197) and longer length of stay (16 vs. 10 days, P<0.0001). High RAPID scores were associated with a higher 90-day mortality (16.3% vs. 2.3%, P=0.0014), and organ failure (81.6% vs. 49.6%, P=0.0001). High RAPID scores with early surgery were associated with higher 90-day mortality (21.4% vs. 0%, P=0.0124), organ failure (78.6% vs. 34.9%, P=0.0044), 30-day readmission (50.0% vs. 16.3%, P=0.027) and length of stay (16 vs. 9 days, P=0.0064). High vs. low RAPID scores with late surgery was associated with a higher rate of organ failure (82.9% vs. 56.7%, P=0.0062), but there was not a significant association with mortality. Conclusions: We found a significant association between RAPID scores and surgical timing with new organ failure. Patients with complicated pleural effusions who had early surgery and low RAPID scores experienced better outcomes including decreased length of stay and organ failure compared with those who had late surgery and low RAPID scores. This suggests that using the RAPID score may help identify those who would benefit from early surgery.
RESUMO
INTRODUCTION: Among critically ill patients undergoing orotracheal intubation in the emergency department (ED) or intensive care unit (ICU), failure to visualise the vocal cords and intubate the trachea on the first attempt is associated with an increased risk of complications. Two types of laryngoscopes are commonly available: direct laryngoscopes and video laryngoscopes. For critically ill adults undergoing emergency tracheal intubation, it remains uncertain whether the use of a video laryngoscope increases the incidence of successful intubation on the first attempt compared with the use of a direct laryngoscope. METHODS AND ANALYSIS: The DirEct versus VIdeo LaryngosCopE (DEVICE) trial is a prospective, multicentre, non-blinded, randomised trial being conducted in 7 EDs and 10 ICUs in the USA. The trial plans to enrol up to 2000 critically ill adults undergoing orotracheal intubation with a laryngoscope. Eligible patients are randomised 1:1 to the use of a video laryngoscope or a direct laryngoscope for the first intubation attempt. The primary outcome is successful intubation on the first attempt. The secondary outcome is the incidence of severe complications between induction and 2 min after intubation, defined as the occurrence of one or more of the following: severe hypoxaemia (lowest oxygen saturation <80%); severe hypotension (systolic blood pressure <65 mm Hg or new or increased vasopressor administration); cardiac arrest or death. Enrolment began on 19 March 2022 and is expected to be completed in 2023. ETHICS AND DISSEMINATION: The trial protocol was approved with waiver of informed consent by the single institutional review board at Vanderbilt University Medical Center and the Human Research Protection Office of the Department of Defense. The results will be presented at scientific conferences and submitted for publication in a peer-reviewed journal. TRIAL REGISTRATION NUMBER: ClinicalTrials.gov Registry (NCT05239195).

Gender is emerging as a factor that may impact the trajectory of critical illness; clinical trials in critical care have largely enrolled men with little attention to equal distribution of sexes. Distribution of admission to the intensive care unit and utilization of resources differs by gender. Sex hormones are thought to impact the course of critical illness. Management and outcomes in sepsis and acute respiratory distress syndrome have been demonstrated to differ by gender as well as in pregnancy. Outcomes of critically ill patients may be impacted by gender.

A 35-year-old man was admitted to the intensive care unit with massive haemoptysis. CT of the chest revealed a necrotic right upper lobe mass. Angiography of his thoracic vasculature revealed a pseudoaneurysm in the right subclavian artery with active contrast extravasation. This anatomic deformity was stented and coiled with the assistance of interventional radiology. Bronchoscopy with lavage and brushings of the right upper lobe mass revealed fungal hyphae and positive galactomannan, supporting that the patient developed invasive pulmonary aspergillosis leading to a mycotic pseudoaneurysm of the right subclavian artery followed by massive haemoptysis.

INTRODUCTION: Hospital admissions and readmissions for chronic obstructive pulmonary disease (COPD) exacerbations are associated with increased mortality and higher cost. The management of exacerbations with a shortened course of systemic corticosteroids has similar efficacy as compared to longer steroid courses, but actual overall steroid dose given is still variable. The outcomes associated with steroid side effects, such as hyperglycemia, need further evaluation. We hypothesized that the use of higher doses of corticosteroids, and the subsequent hyperglycemia, contributes to readmission. METHODS: This is a retrospective study at a tertiary care referral center in central Texas between February 2014 and July 2016. Daily corticosteroid dose, blood glucose levels, and readmission rates at 30 and 31-90 days were recorded. Sample characteristics are described using descriptive statistics. A chi-square test or student's t-test were used to test for associations in bivariate comparisons. Multivariable logistic regression assessed the association between readmission rate and demographic and clinical characteristics. RESULTS: There were 1120 patients admitted for COPD exacerbation between February 2014 and July 2016. A total of 57% were female, mean age was 69 years (standard deviation [SD] 12), and average body mass index (BMI) was 29.4 (SD 9.8). Of the total, 349 (31%) had diabetes prior to admission. The 30-day readmission rate was 16%, and the readmission rate from 31-90 days was 14%. The average prednisone equivalent dose per day during hospitalization was 86 mg (SD 52). A multivariable logistic regression model did not show any significant association between readmission and average daily glucose, high maximum glucose (>180 mg/dL on any reading), or prednisone equivalent administered per day. CONCLUSION: Corticosteroid dose and hyperglycemia were not associated with an increased 30-day or 31-90-day readmission rate after COPD exacerbation discharge. In addition, using higher doses of corticosteroids instead of standard-of-care (prednisone 40 mg per day for a 5-day period) did not appear to affect the readmission rate in this cohort.
RESUMO
Bronchus-associated lymphoid tissue (BALT) lymphomas of the lung are uncommon, and diagnosis is often delayed due to the indolent clinical course. Often, adequate samples are difficult to obtain by bronchoscopy with transbronchial biopsy alone. This retrospective study reviewed the diagnosis and treatment of BALT lymphoma cases at our institution over the course of 19 years. Most patients were white, women, and >50 years old; the mean Charlson Comorbidity Index at the time of diagnosis was 6. Seven of 12 patients presented with solitary nodules or multiple nodules. For six cases, initial modalities were nondiagnostic; four subsequently underwent surgical biopsy, one underwent computed tomography-guided biopsy, and one underwent navigational bronchoscopy for final diagnosis of BALT lymphoma. Ultimately, 55% of cases were diagnosed with nonsurgical biopsy. One patient suffered a pneumothorax related to the initial diagnostic attempt. Ten patients received chemotherapy, radiation, and/or surgery, and 11 of the 12 are still alive. Our data confirm the previously described indolent behavior of BALT lymphomas and the challenges related to diagnosis. While previous studies have suggested surgical biopsy as the primary modality for obtaining histopathology, navigational bronchoscopy could serve as a safer alternative.
RESUMO
BACKGROUND: Conflicts in medical settings affect both team function and patient care, yet a standardized curriculum for conflict management in clinical teams does not exist. OBJECTIVES: To evaluate the effects of an educational intervention for conflict management on knowledge and perceptions and to identify trends in preferred conflict management style among intensive care unit workers. METHODS: A conflict management education intervention was created for an intensive care team. The intervention was 1 hour long and incorporated the Thomas-Kilmann Conflict Mode Instrument as well as conflict management concepts, self-reflection, and active learning through discussion and reviewing clinical cases. Descriptive statistics were prepared on the participants' preferred conflict management modes. A pretest/posttest was analyzed to evaluate knowledge and perceptions of conflict before and after the intervention, and 3 open-ended questions on the posttest were reviewed for categories. RESULTS: Forty-nine intensive care providers participated in the intervention. The largest portion of participants had an avoiding conflict management mode (32%), followed by compromising (30%), accommodating (25%), collaborating (9%), and competing (5%). Pretest/posttest data were collected for 31 participants and showed that knowledge (P < .001) and perception (P = .004) scores increased significantly after the conflict management intervention. CONCLUSIONS: The conflict management educational intervention improved the participants' knowledge and affected perceptions. Categorization of open-ended questions suggested that intensive care providers are interested in concrete information that will help with conflict resolution, and some participants understood that mindfulness and awareness would improve professional interactions or reduce conflict.

INTRODUCTION: Cardiovascular collapse is a common complication during tracheal intubation of critically ill adults. Whether administration of an intravenous fluid bolus prevents cardiovascular collapse during tracheal intubation remains uncertain. A prior randomised trial found fluid bolus administration to be ineffective overall but suggested potential benefit for patients receiving positive pressure ventilation during tracheal intubation. METHODS AND ANALYSIS: The PREventing cardiovascular collaPse with Administration of fluid REsuscitation during Induction and Intubation (PREPARE II) trial is a prospective, multi-centre, non-blinded randomised trial being conducted in 13 academic intensive care units in the USA. The trial will randomise 1065 critically ill adults undergoing tracheal intubation with planned use of positive pressure ventilation (non-invasive ventilation or bag-mask ventilation) between induction and laryngoscopy to receive 500 mL of intravenous crystalloid or no intravenous fluid bolus. The primary outcome is cardiovascular collapse, defined as any of: systolic blood pressure <65 mm Hg, new or increased vasopressor administration between induction and 2 min after intubation, or cardiac arrest or death between induction and 1 hour after intubation. The primary analysis will be an unadjusted, intention-to-treat comparison of the primary outcome between patients randomised to fluid bolus administration and patients randomised to no fluid bolus administration using a χ2 test. The sole secondary outcome is 28-day in-hospital mortality. Enrolment began on 1 February 2019 and is expected to conclude in June 2020. ETHICS AND DISSEMINATION: The trial was approved by either the central institutional review board at Vanderbilt University Medical Center or the local institutional review board at each trial site. Results will be submitted for publication in a peer-reviewed journal and presented at scientific conferences. TRIAL REGISTRATION NUMBER: NCT03787732.

BACKGROUND: Diabetic ketoacidosis (DKA) has an associated mortality of 1% to 5%. Upon admission, patients require insulin infusion and close monitoring of electrolyte and blood sugar levels with subsequent transitioning to subcutaneous insulin and oral nutrition. No recommendations exist regarding the appropriate timing for initiation of oral nutrition. AIM: To assess short-term outcomes of oral nutrition initiated within 24 h of patients being admitted to a medical intensive care unit (MICU) for DKA. METHODS: A retrospective observational cohort study was conducted at a single academic medical center. The patient population consisted of adults admitted to the MICU with the diagnosis of DKA. Baseline characteristics and outcomes were compared between patients receiving oral nutrition within (early nutrition group) and after (late nutrition group) the first 24 h of admission. The primary outcome was 28-d mortality. Secondary outcomes included 90-d mortality, MICU and hospital lengths of stay (LOS), and time to resolution of DKA. RESULTS: There were 128 unique admissions to the MICU for DKA with 67 patients receiving early nutrition and 61 receiving late nutrition. The APACHE (Acute Physiology and Chronic Health Evaluation) IV mortality and LOS scores and DKA severity were similar between the groups. No difference in 28- or 90-d mortality was found. Early nutrition was associated with decreased hospital and MICU LOS but not with prolonged DKA resolution, anion gap closure, or greater rate of DKA complications. CONCLUSION: In patients with DKA, early nutrition was associated with a shorter MICU and hospital LOS without increasing the rate of DKA complications.
RESUMO
Interhospital transfers are independently associated with inpatient mortality, and transferred patients have worse outcomes. The aim of this study was to retrospectively assess the 48-hour mortality rate in interhospital transfer cohorts of all transfers to a Central Texas teaching hospital and to identify a primary admitting diagnosis for potential intervention. A total of 15,435 patients with 19,161 transfers over the course of the study were retrospectively reviewed and placed in 18 different categories based upon the primary admitting diagnosis. There were about 5000 transfer patients yearly with â¼1.4% deaths within 48 hours of arrival. The three leading categories for transferred patients were cardiovascular, neurologic, and psychiatric. In this group, 268 of 19,161 transfers died within 48 hours of arrival. Despite being the 10th leading category for transfer, sepsis was the leading primary admitting diagnosis of patients who died within 48 hours of arrival, accounting for nearly 22% of those patients. Given the significant association found between sepsis and 48-hour mortality after transfer, we devised a novel interhospital transfer checklist based upon the Surviving Sepsis guidelines in an attempt to decrease mortality associated with these transfers.
RESUMO
Angiotensin-converting enzyme (ACE) inhibitors and statins may potentially benefit patients with viral infections and pneumonia. Our study aimed to evaluate the impact of ACE inhibitors and statins on the rates of intubation and death in viral pneumonia. We retrospectively studied 1055 adult patients admitted to a tertiary care center in central Texas with a positive respiratory viral polymerase chain reaction test. Of these, 539 had clinical presentation and imaging consistent with pneumonia. We collected information on demographic characteristics, microbiology, comorbid conditions, medication use, and outcomes. ACE inhibitors given prior to admission were associated with an increased risk of death or intubation (odds ratio [OR] = 3.02; 95% confidence interval [CI], 1.30-7.01), whereas statin use prior to admission did not change rates of death or intubation. Lower rates of death and intubation were noted with continued use of ACE inhibitors (OR =0.25; 95% CI, 0.09-0.64) and statins (OR =0.26; 95% CI, 0.08-0.81) throughout the hospital stay. We added further evidence of the beneficial effect of continued use of ACE inhibitors and statins in viral pneumonia.

Acid-base status is frequently assessed in severe sepsis and septic shock. Venous blood gas sampling is proposed as a less-invasive modality but lacks evidence within this population. The objective of this study was to evaluate the correlation and agreement between arterial blood gas (ABG), peripheral venous blood gas (pVBG), and central venous blood gas (cVBG) in severe sepsis and septic shock. We conducted a prospective, observational cohort study in subjects admitted to the medical intensive care unit. Simultaneous blood gas samples, including ABG, pVBG, and cVBG, were analyzed for correlation and agreement. Severity of illness scores revealed a mean (±SD) Sequential Organ Failure Assessment score of 7.9 ± 3.3, Simplified Acute Physiology II score of 49.3 ± 16.5, and a mortality rate of 11.9% in the intensive care unit and 16.4% in the hospital. We found a strong intraclass correlation (>0.85) for pH, partial pressure of carbon dioxide (pCO2), bicarbonate, and base excess for ABG/pVBG, ABG/cVBG, and pVBG/cVBG comparisons. Agreement by the Bland-Altman method was found for pH (bias ± SD, 0.03 ± 0.04, 0.03 ± 0.02, and 0.00 ± 0.03) but not for pCO2, partial pressure of oxygen, bicarbonate, base excess, and oxyhemoglobin saturation. In conclusion, adequate correlation and agreement between ABG/pVBG, ABG/cVBG, and pVBG/cVBG comparisons was found only for pH. The current level of evidence does not support the use of venous blood gas sampling in this setting.
