RESUMEN
BACKGROUND: We aimed to determine the epidemiology and outcomes of unplanned extubation (UE), both accidental and self-extubation, in ICU. METHODS: A multicentre prospective cohort study was conducted in 47 French ICUs. The number of mechanical ventilation (MV) days, and planned and unplanned extubation were recorded in each center over a minimum period of three consecutive months to evaluate UE incidence. Patient characteristics, UE environmental factors, and outcomes were compared based on the UE mechanism (accidental or self-extubation). Self-extubation outcomes were compared with planned extubation using a propensity-matched population. Finally, risk factors for extubation failure (re-intubation before day 7) were determined following self-extubation. RESULTS: During the 12-month inclusion period, we found a pooled UE incidence of 1.0 per 100 MV days. UE accounted for 9% of all endotracheal removals. Of the 605 UE, 88% were self-extubation and 12% were accidental-extubations. The latter had a worse prognosis than self-extubation (34%vs. 8% ICU-mortality, p < 0.001). Self-extubation did not increase mortality compared with planned extubation (8 vs. 11%, p = 0.075). Regardless of the type of extubation, planned or unplanned, extubation failure was independently associated with a poor outcome. Cancer, higher respiratory rate, lower PaO2/FiO2 at the time of extubation, weaning process not-ongoing, and immediate post-extubation respiratory failure were independent predictors of failed self-extubation. CONCLUSION: Unplanned extubation, mostly represented by self-extubation, is common in ICU and accounts for 9% of all endotracheal extubations. While accidental extubations are a serious and infrequent adverse event, self-extubation does not increase mortality compared to planned extubation.
RESUMEN
We present our findings on interpatient transmission, epidemic control measures, and the outcomes of a series of ten critically ill burn patients who were either colonized or infected with carbapenem-resistant Acinetobacter baumannii (CRAB). None of the five infected patients achieved clinical cure, and all experienced relapses. Microbiological failure was observed in 40% of the infected patients. The isolated CRAB strains were found to carry blaOXA-23 and armA resistance genes. Despite the lack of clinical cure, all five infected patients survived and were discharged from the Burn Intensive Care Unit.

BACKGROUND: Esophagectomy is associated with significant mortality. A better understanding of the causes leading to death may help to reduce mortality. A root cause analysis of mortality after esophagectomy was performed. METHODS: Root cause analysis was retrospectively applied by an independent expert panel of 4 upper gastrointestinal surgeons and 1 anesthesiologist-intensivist to patients included in the French national multicenter prospective cohort FREGAT between August 2014 and September 2019 who underwent an esophagectomy for cancer and died within 90 days of surgery. A cause-and-effect diagram was used to determine the root causes related to death. Death was classified as potentially preventable or non-preventable. RESULTS: Among the 1,040 patients included in the FREGAT cohort, 70 (6.7%) patients (male: 81%, median age 68 [62-72] years) from 17 centers were included. Death was potentially preventable in 37 patients (53%). Root causes independently associated with preventable death were inappropriate indication (odds ratio 35.16 [2.50-494.39]; P = .008), patient characteristics (odds ratio 5.15 [1.19-22.35]; P = .029), unexpected intraoperative findings (odds ratio 18.99 [1.07-335.55]; P = .045), and delay in diagnosis of a complication (odds ratio 98.10 [6.24-1,541.04]; P = .001). Delay in treatment of a complication was found only in preventable deaths (28 [76%] vs 0; P < .001). National guidelines were less frequently followed (16 [43%] vs 22 [67%]; P = .050) in preventable deaths. The only independent risk factor of preventable death was center volume <26 esophagectomies per year (odds ratio 4.71 [1.55-14.33]; P = .006). CONCLUSIONS: More than one-half of deaths after esophagectomy were potentially preventable. Better patient selection, early diagnosis, and adequate management of complications through centralization could reduce mortality.

INTRODUCTION: Delayed graft function (DGF) is a frequent complication following kidney transplant. This study aimed to assess the association between early post-operative lactate variation and DGF. METHODS: This was a single center, retrospective cohort study between February 2021 and December 2022 in Saint-Louis Hospital (APHP, France). Venous lactate levels were measured immediately (H0) and 4 h (H4) after kidney transplant. The primary outcome was the occurrence of DGF (need for renal replacement therapy between transplantation and day 7). Secondary outcome was the occurrence of complications (i.e., death, vascular thrombosis, hemorrhagic shock, urological complications (hematoma, urinoma), local or systemic infection) between transplant and day 7. RESULTS: Two hundred 12 patients were included, and 38 (17.9%) developed DGF. Venous lactate variation between H0 and H4 was higher in patients who developed DGF (-30 (IQR -83, -6)% vs. -15 (IQR -62, -11)%, p = .037), but the variation of level was more often positive (corresponding to an increased lactate production over time between H0 and H4) in patients who developed DGF ((28(85%) vs. 94(62%), p = .011). In multivariate logistic regression, positive venous lactate level variation between H0 and H4 was strongly associated with a reduced risk of developing DGF (OR .30 [.09-.79], p = .024). We did not find any association between post-operative hyperlactatemia and occurrence of complications between transplant and day 7. DISCUSSION: DGF is a frequent complication following kidney transplantation. Its early prediction could help physicians optimize treatment and protect the kidney. Early venous lactate variation after kidney transplant could help to predict the occurrence of DGF.

PURPOSE: Caustic ingestion is a potential life-threatening condition associated with high morbidity and mortality. Data on patients admitted to Intensive Care Unit (ICU) for severe caustic ingestion are lacking. We aimed to describing epidemiological features and outcomes of patients admitted to ICU for caustic ingestion in France. METHODS: In a retrospective, observational, and multicenter study, data from the national French Programme de Médicalisation des Systèmes d'Informations (PMSI) database were analysed from 2013 to 2019. In-hospital mortality rate (primary outcome) and in-ICU complications (secondary outcomes) were reported and analysed. RESULTS: 569 patients (289 males (50.8%), with median age of 49 years [interquartile (26-62)] were admitted in 65 French ICU for severe caustic ingestion. Five hundred and thirteen patients (90%) were admitted for intentional caustic ingestion. The median length of stay in ICU was 14.0 [4.0-31.0] days. In-hospital mortality occurred in 56 patients (9.8%). In multivariate analysis, age and simplified acute physiology score II were associated with in-hospital mortality age of 40-59 years [OR = 15.3 (2.0-115.3)], age of 60-79 years [OR = 23.6 (3.1-182.5)], and age > 80 years [OR = 37.0 (4.2-328.6)] and SAPS 2 score [OR = 1.0018 (1.003-1.033), p < 0.001]. During ICU stay, 423 complications (74%) were reported in 505 patients (89%). Infectious (244 (42.9%)), respiratory (207 (36.4%)), surgical 62 (10.9%), haemorrhagic (64 (11.2%)) and thrombo-embolic and (35 (6.2%)) complications were the most frequently reported during ICU stay. CONCLUSION: ICU admission for severe caustic ingestion is associated with 9.8% mortality and 74% complications. Age > 40 years and SAPS 2 score were independently associated with mortality.

PURPOSE: The impact of VA-ECMO on early renal recovery (within 7 days after ECMO onset) in patients with pre-ECMO acute kidney injury and cardiogenic shock is unknown. MATERIAL AND METHODS: This retrospective single-center study included adult patients with cardiogenic shock rescued by VA-ECMO and severe AKI occurring before ECMO implantation (pre-ECMO AKI). Patients with early renal recovery (defined as at least a 50% decrease in peak serum creatinine or weaning from renal replacement therapy) were compared to patients without early renal recovery. RESULTS: During 7 years, 145 patients with severe pre-ECMO AKI were included. Eighty-two patients had no early renal recovery whereas 63 had early renal recovery within 7 days after VA-ECMO onset. The median time to early renal recovery was 4 (3,6) days. Nephrotoxic antibiotics (HR = 0.35 [95% CI, 0.21-0.59], p < 0.001), median fluid balance during the first 7 days of VA-ECMO (HR = 0.77 [95% CI, 0.64-0.93], p = 0.008), pre-ECMO AKI stage 3 (HR = 0.36 [95% CI, 0.20-0.64], p < 0.001) and median vasoactive-inotropic score (HR = 0.99 [95% CI, 0.98,1.00], p = 0.035) were independently associated with no early renal recovery. CONCLUSIONS: Only 43% of patients with severe pre-ECMO AKI had early renal recovery after VA-ECMO initiation.

BACKGROUND: Severe hypothyroidism (SH) is a rare but life-threatening endocrine emergency. Only a few data are available on its management and outcomes of the most severe forms requiring ICU admission. We aimed to describe the clinical manifestations, management, and in-ICU and 6-month survival rates of these patients. METHODS: We conducted a retrospective, multicenter study over 18 years in 32 French ICUs. The local medical records of patients from each participating ICU were screened using the International Classification of Disease 10th revision. Inclusion criteria were the presence of biological hypothyroidism associated with at least one cardinal sign among alteration of consciousness, hypothermia and circulatory failure, and at least one SH-related organ failure. RESULTS: Eighty-two patients were included in the study. Thyroiditis and thyroidectomy represented the main SH etiologies (29% and 19%, respectively), while hypothyroidism was unknown in 44 patients (54%) before ICU admission. The most frequent SH triggers were levothyroxine discontinuation (28%), sepsis (15%), and amiodarone-related hypothyroidism (11%). Clinical presentations included hypothermia (66%), hemodynamic failure (57%), and coma (52%). In-ICU and 6-month mortality rates were 26% and 39%, respectively. Multivariable analyses retained age > 70 years [odds ratio OR 6.01 (1.75-24.1)] Sequential Organ-Failure Assessment score cardiovascular component ≥ 2 [OR 11.1 (2.47-84.2)] and ventilation component ≥ 2 [OR 4.52 (1.27-18.6)] as being independently associated with in-ICU mortality. CONCLUSIONS: SH is a rare life-threatening emergency with various clinical presentations. Hemodynamic and respiratory failures are strongly associated with worse outcomes. The very high mortality prompts early diagnosis and rapid levothyroxine administration with close cardiac and hemodynamic monitoring.

INTRODUCTION: Recent studies have shown the prognostic value of capillary refill time (CRT) and suggested that resuscitation management guided by CRT may reduce morbidity and mortality in patients with septic shock. However, little is known about the current use of CRT in routine clinical practice. This study aimed to assess the modalities of CRT use among French adult and pediatric intensivists. METHODS: A cross-sectional survey exploring CRT practices in acute circulatory failure was performed. The targeted population was French adult and pediatric intensivists (SFAR and GFRUP networks). An individual invitation letter including a survey of 32 questions was emailed twice. Descriptive and analytical statistics were performed. RESULTS: Among the 6071 physicians who received the letter, 418 (7%) completed the survey. Among all respondents, 82% reported using CRT in routine clinical practice, mainly to diagnose acute circulatory failure, but 45% did not think CRT had any prognostic value. Perfusion goal-directed therapy based on CRT was viewed as likely to improve patient outcome by 37% of respondents. The measurement of CRT was not standardized as the use of a chronometer was rare (3%) and the average of multiple measurements rarely performed (46%). Compared to adult intensivists, pediatric intensivists used CRT more frequently (99% versus 76%) and were more confident in its diagnostic value and its ability to guide treatment. CONCLUSION: CRT measurement is widely used by intensivists in patients with acute circulatory failure but most often in a non-standardized way. This may lead to a misunderstanding of CRT reliability and clinical usefulness.

INTRODUCTION: Lactate albumin ratio (LAR) has been used as a prognostic marker associated with organ failure in critically ill septic patients. LAR and its association with outcomes has never been studied in burned patients. The aim of this study was to evaluate the ability of LAR to predict 28-day mortality. METHODS: A retrospective cohort study including all burn patients hospitalized in intensive care unit. The primary endpoint was the 28-day mortality. RESULTS: One thousand three hundred thirty four patients were screened, and 471 were included between June 2012 and December 2018. Briefly, the population study was mainly composed by men (249, 59.1%), the median age, TBSA burned, full thickness, ABSI and IGS2 were 52 [34-68], 20 [10-40], 8 [1-23], 7 [5-9] and 25 [15-40] respectively. Fifty-two patients (12.4%) died at day 28 after admission. At admission, the LAR level was lower in 28-day survivors compared non-survivors (0.05 [0.04, 0.08] vs 0.12 [0.07, 0.26], p < 0.001 respectively). In multivariate analysis accounting for ABSI, LAR levels at admission> 0.13 was independently associated with 28-day mortality (adjusted OR = 3.98 (IC95 1.88-8.35)). The ability of LAR at admission to discriminate 28-day mortality showed an AUC identical when compared to SOFA and ABSI scores (0.81 (IC95 0.74-0.88), 0.80 (IC95 0.72-0.85) and (0.85 (IC95 0.80-0.90), p < 0.05, respectively). Patients with LAR levels ≥ 0.13 at admission had higher 28-day mortality (40.6% vs 6.8%, p < 0.001, HR 7.39 (IC95 4.28-12.76)). CONCLUSION: At admission, LAR is an easy and reliable marker independently associated to 28-day mortality in patients with severe burn injury, but prediction by LAR does not perform better than lactate level alone.

Rationale: Dyspnea is a traumatic experience. Only limited information is available on dyspnea in intubated critically ill patients. Objectives: Our objectives were 1) to quantify the prevalence and severity of dyspnea; and 2) to evaluate the impact of dyspnea on ICU length of stay and post-traumatic stress disorder (PTSD) 90 days after ICU discharge. Methods: This was a prospective cohort study in 10 ICUs in France. In patients intubated for more than 24 hours, dyspnea was quantified with a visual analog scale (from 0 to 10) as soon as they were able to communicate, the following day, and before spontaneous breathing trials. PTSD was defined by an Impact of Event Scale-Revised score of at least 22. Measurements and Main Results: Among the 612 patients assessed, 34% reported dyspnea, with a median dyspnea rating of 5 (interquartile range, 4-7). ICU length of stay was not significantly different between patients with versus without dyspnea (6 [3-12] and 6 [3-13] days, respectively; P = 0.781). Mortality was not different between groups. Of the 153 patients interviewed on Day 90, a higher proportion of individuals with probable PTSD was observed among patients who were dyspneic on enrollment (29% vs. 13%; P = 0.017). The density of dyspnea (number of dyspneic episodes divided by time from enrollment to extubation) was independently associated with PTSD (odds ratio, 1.07; 95% confidence interval, 1.01-1.13; P = 0.031). Conclusions: Dyspnea was frequent and intense in intubated critically ill patients. ICU length of stay was not significantly different among patients reporting dyspnea, but PTSD was more frequent at Day 90. Clinical trial registered with www.clinicaltrials.gov (NCT02336464).

BACKGROUND: The aim of this study was to describe the prevalence, characteristics and outcome of critically burn patients with pulmonary HSV reactivation. METHODS: Retrospective, single-center cohort study in a burn critical care unit in a tertiary center, including all consecutive severely burn patients with bronchoalveolar lavage performed for pneumoniae suspicion and screened for HSV from January 2013 and April 2017. We used logistic regression to identify factors associated with HSV reactivation and outcomes. RESULTS: 94 patients were included, mean age was 51 (39-64) years; median total body surface area burned was 36 (25-54)% and ICU mortality 38%. Fifty-five patients (59%) had pulmonary HSV reactivation and 30 (55%) were treated with acyclovir. Patients with HSV reactivation were more severely ill with higher SOFA score at admission compared to patient without HSV reactivation (6 [3-8] vs. 2 [1-4], p < 0.0001 respectively). In multivariate analysis, sex, SOFA score at admission and smoke inhalation were significantly associated with HSV reactivation. Only septic shock was associated with 90-day mortality when HSV reactivation was not. CONCLUSIONS: Pulmonary HSV reactivation is frequent among severely ill burn patients. Initial severity and smoke inhalation are risk factors. Antiviral treatment was not associated with outcome.

Photoplethysmography (PPG) has been extensively used for pulse oximetry monitoring in anaesthesia, perioperative and intensive care. However, some components of PPG signal have been employed for other purposes, such as non-invasive haemodynamic monitoring. Perfusion index (PI) is derived from PPG signal and represents the ratio of pulsatile on non-pulsatile light absorbance or reflectance of the PPG signal. PI determinants are complex and interlinked, involving and reflecting the interaction between peripheral and central haemodynamic characteristics, such as vascular tone and stroke volume. Recently, several studies have shed light on the interesting performances of this variable, especially assessing regional or neuraxial block success, and haemodynamic monitoring in anaesthesia, perioperative and intensive care. Nevertheless, no review has yet been published concerning the interest of PI in these fields. In this narrative review will be exposed first the physiological and pathophysiological determinants of PI, and then the mean to measure this value as well as its potential limitations. In the second part, the existing data concerning usefulness of PI in different clinical settings such as operating theatres, intensive care units and emergency departments will be presented and discussed. Finally, the perspectives concerning the use of PI and mentioned aspects that should be explored regarding this tool will be underlined.

BACKGROUND: Severe acute respiratory syndrome coronavirus 2 disease is strongly associated with a high incidence of thrombotic events. Anticoagulation could be a cornerstone in successfully managing severe forms of coronavirus disease 2019 (COVID-19). However, optimal anticoagulant dosing in elderly patients is challenging because of high risk of both thrombosis and bleeding. CASE SUMMARY: We present here the case of an 89-year-old patient receiving warfarin for atrial fibrillation and valvular heart disease, admitted to the intensive care unit for respiratory failure due to COVID-19. The patient presented with a severe epistaxis associated with warfarin overdose [international normalized ratio (INR) > 10]. After a successful initial reversal using vitamin K per os, INR values greatly fluctuated up to 10, requiring repeated administrations of vitamin K. Despite starting low-molecular-weight heparin therapy at therapeutic dose as soon as INR value was below 2.0, the patient further developed an acute bilateral and proximal pulmonary embolism concomitantly with a sharp D-dimer increase. The combination of azithromycin intake, a known inhibitor of CYP2C9, with the presence of CYP2C9*2 and -1639G>A VKORC1, two variants associated with warfarin hypersensitivity, have likely contributed to explain the warfarin overdose and the difficulty to reverse warfarin effect in this patient. DISCUSSION: This case report illustrates the complexity of COVID-19 pathophysiology and its management for physicians, especially in patients receiving vitamin K antagonists (VKAs). Infection, concurrent medication use, and pharmacogenetic factors involved in VKA metabolism and pharmacodynamics may lead to a loss of control of anticoagulation. Pulmonary embolism should still be considered in COVID-19 patients even with effective or overdosed anticoagulant therapy.
RESUMEN
Hypotension during general anesthesia is associated with poor outcome. Continuous monitoring of mean blood pressure (MAP) during anesthesia is useful and needs to be reliable and minimally invasive. Conventional cuff measurements can lead to delays due to its discontinuous nature. It has been shown that there is a relationship between MAP and photoplethysmography (PPG) parameters like the dicrotic notch and perfusion index (PI). The objective of the study was to continuously estimate MAP from PPG. Pulse wave analysis based on PPG was implemented using either notch relative amplitude (MAPNRA), notch absolute amplitude (MAPNAA) or PI (MAPPI) to estimate MAP from PPG waveform features during general anesthesia. Estimated MAP values were compared to brachial cuff MAP (MAPcuff) and to radial invasive MAP (MAPinv). Forty-six patients were analyzed for a total of 235 h. Compared to MAPcuff, mean bias and limits of agreement were 1 mmHg (- 26 to +29), - 1 mmHg (- 10 to +8) and - 3 mmHg (- 21 to +13) for MAPNRA, MAPNAA and MAPPI respectively. Compared to MAPinv, mean absolute error (MAE) was 20 mmHg [10 to 39], 11 mmHg [5 to 18] and 16 mmHg [9 to 24] for MAP derived from MAPNRA, MAPNAA and MAPPI respectively. When calibrated every 5 min, MAPNAA showed a MAE of 6 mmHg [5 to 9]. MAPNAA provides the best estimates with respect to brachial cuff MAP and invasive MAP. Regular calibration allows to reduce drift over time. Beat to beat estimation of MAP during general anesthesia from the PPG appears possible with an acceptable average error.

The FilmArray® Pneumonia Plus (FA-PP) panel can provide rapid identifications and semiquantitative results for many pathogens. We performed a prospective single-center study in 43 critically ill patients with coronavirus disease 2019 (COVID-19) in which we performed 96 FA-PP tests and cultures of blind bronchoalveolar lavage (BBAL). FA-PP detected 1 or more pathogens in 32% (31/96 of samples), whereas culture methods detected at least 1 pathogen in 35% (34/96 of samples). The most prevalent bacteria detected were Pseudomonas aeruginosa (nâ¯=â¯14) and Staphylococcus aureus (nâ¯=â¯11) on both FA-PP and culture. The FA-PP results from BBAL in critically ill patients with COVID-19 were consistent with bacterial culture findings for bacteria present in the FA-PP panel, showing sensitivity, specificity, and positive and negative predictive value of 95%, 99%, 82%, and 100%, respectively. Median turnaround time for FA-PP was 5.5â¯h, which was significantly shorter than for standard culture (26â¯h) and antimicrobial susceptibility testing results (57â¯h).

The pathophysiology of acute kidney injury (AKI) in COVID-19 patients is still poorly understood. SARS-CoV-2 has been suggested to modulate the renin-angiotensin-aldosterone system (RAAS). In this series of COVID-19 critically ill patients, we report evidence of activation of the RAAS in COVID-19 patients with AKI.
