ABSTRACT
BACKGROUND: Posttraumatic stress disorder (PTSD) after a stay in the intensive care unit (ICU) can affect one in five ICU survivors. At the beginning of the coronavirus disease 2019 (COVID-19) pandemic, admission to the ICU for COVID-19 was stressful due to the severity of this disease. This study assessed whether admission to the ICU for COVID-19 was associated with a higher prevalence of PTSD compared with other causes of ICU admission after adjustment for pre-ICU psychological factors. METHODS: This prospective observational comparative cohort study included 31 ICUs. Eligible patients were adult ICU survivors hospitalized during the first wave of COVID-19 pandemic in France, regardless of the reason for admission. The prevalence of presumptive diagnosis of PTSD at 6 months was assessed using the PTSD Checklist for DSM-5 (PCL-5). Sociodemographics, clinical data, history of childhood trauma (Childhood Trauma Questionnaire [CTQ]), and exposure to potentially traumatic events (Life Events Checklist for DSM-5 [LEC-5]) were assessed. RESULTS: Of the 778 ICU survivors included during the first wave of COVID-19 pandemic in France, 417 and 361 were assigned to the COVID-19 and non-COVID-19 cohorts, respectively. Fourteen (4.9%) and 11 (4.9%), respectively, presented with presumptive diagnosis of PTSD at 6 months (p = 0.976). After adjusting for age, sex, severity score at admission, use of invasive mechanical ventilation, ICU duration, CTQ and LEC-5, COVID-19 status was not associated with presumptive diagnosis of PTSD using the PCL-5. Only female sex was associated with presumptive diagnosis of PTSD. However, COVID-19 patients reported significantly more intrusion and avoidance symptoms than non-COVID patients (39% vs. 29%, p = 0.015 and 27% vs. 19%, p = 0.030), respectively. The median PCL-5 score was higher in the COVID-19 than non-COVID-19 cohort (9 [3, 20] vs. 4 [2, 16], p = 0.034). CONCLUSION: Admission to the ICU for COVID-19 was not associated with a higher prevalence of PTSD compared with admission for another cause during the first wave of the COVID-19 pandemic in France. However, intrusion and avoidance symptoms were more frequent in COVID-19 patients than in non-COVID-19 patients.

BACKGROUND: The short-term and long-term consequences of the most frequent painful procedures performed in the ICU are unclear. This study aimed to identify the risk factors associated with pain-related discomfort perceived by critically ill patients during the whole ICU stay as self-reported by patients at the end of their ICU stay. METHODS: The study involved 34 ICUs. Adult patients who survived an ICU stay of 3 calendar days or more were eligible for inclusion. Discomforts, including the pain-related discomfort, were assessed using the French 18-item questionnaire on discomfort in ICU patients, the "Inconforts des Patients de REAnimation" (IPREA). Patients scored each item from 0 (minimal discomfort) to 10 (maximal discomfort). Associations between patient characteristics at ICU admission, life support therapies and main potentially painful procedures performed during the ICU stay and pain-related discomfort scores assessed at the end of the ICU stay were analyzed. RESULTS: Patients with complete IPREA questionnaires (n = 2130) were included. The median pain-related discomfort score was 3 (IQR 0-5). From the univariate analysis, pain-related discomfort scores were negatively correlated with age and positively correlated with ICU stay duration; surgical patients reported significant higher pain-related discomfort scores than medical patients; chest drain insertion, chest drain removal, use of bladder catheter, central venous catheter (CVC) insertion, complex dressing change, and intra-hospital transport were associated with pain-related discomfort scores. From the multivariate analyses using generalized estimating equations models, only age, chest drain removal, use of a bladder catheter, CVC insertion, and intra-hospital transport were the main risk factors associated with pain-related discomfort scores. CONCLUSION: Patients who underwent chest drain removal, bladder catheter, CVC insertion, and intra-hospital transport during their ICU stay reported higher pain-related discomfort scores (with respect to the whole ICU stay and assessed at the end of their ICU stay) than patients who did not experience these events. This study may pave the way for further targeted studies aiming at investigating a causal link between these common procedures in the ICU and adult critically ill patients' perceptions of their ICU stay regarding recalled pain.

BACKGROUND AND AIMS: We reported the validation of the 18-item version of the 'Inconforts des Patients de REAnimation (IPREA)' questionnaire that includes 2 new items exploring feeling depressed and shortness of breath during an intensive care unit (ICU) stay. METHODS: The validation process was integrated in a multicenter, cluster-randomized, controlled, two-parallel group study built to assess the effectiveness of a tailored multicomponent program for reducing self-perceived discomfort in the ICU. All patients aged 18 years or older who survived an ICU stay of 3 calendar days or more were eligible for inclusion. Data collection included demographics (sex, age), type of admission (medical and surgical), health status scores at admission (Knaus score and McCabe index, Simplified Acute Physiology Score (SAPS) II), specific ICU therapeutics such as mechanical ventilation (MV), noninvasive ventilation (NIV), use of vasopressors, or renal replacement therapy (RRT), and ICU stay duration. RESULTS: A total of 994 patients were included. The initial structure of IPREA was confirmed using confirmatory factor analysis showing satisfactory fit (RMSEA at 0.042, CFI at 0.912). No multidimensional structure was identified, allowing the calculation of an overall discomfort score. The three highest discomforts were sleep deprivation, thirst, and perfusion lines and other devices, and the 3 lowest discomforts were limited visiting hours, hunger, and isolation. The overall discomfort score of the 18-item version of IPREA did not differ between men and women. Higher age was significantly correlated with a lower overall discomfort score. While MV was not linked to self-reported discomfort, patients treated by NIV reported higher overall discomfort scores than patients not treated by NIV. CONCLUSION: The 18-item version of IPREA is easy to use and possesses satisfactory psychometric properties. The availability of a reliable and valid French questionnaire asking about patients' self-perceived ICU discomforts enables feedback from the health care team to be incorporated in a continuous quality health care improvement strategy.

OBJECTIVE: To assess the safety and efficacy of combining extracorporeal CO2 removal with continuous renal replacement therapy in patients presenting with acute respiratory distress syndrome and acute kidney injury. DESIGN: Prospective human observational study. SETTINGS: Patients received volume-controlled mechanical ventilation according to the acute respiratory distress syndrome net protocol. Continuous venovenous hemofiltration therapy was titrated to maintain maximum blood flow and an effluent flow of 45 mL/kg/h with 33% predilution. PATIENTS: Eleven patients presenting with both acute respiratory distress syndrome and acute kidney injury required renal replacement therapy. INTERVENTIONS: A membrane oxygenator (0.65 m) was inserted within the hemofiltration circuit, either upstream (n = 7) or downstream (n = 5) of the hemofilter. Baseline corresponded to tidal volume 6 mL/kg of predicted body weight without extracorporeal CO2 removal. The primary endpoint was 20% reduction in PaCO2 at 20 minutes after extracorporeal CO2 removal initiation. Tidal volume was subsequently reduced to 4 mL/kg for the remaining 72 hours. MEASUREMENTS AND MAIN RESULTS: Twelve combined therapies were conducted in the 11 patients. Age was 70 ± 9 years, Simplified Acute Physiology Score II was 69 ± 13, Sequential Organ Failure Assessment score was 14 ± 4, lung injury score was 3 ± 0.5, and PaO2/FIO2 was 135 ± 41. Adding extracorporeal CO2 removal at tidal volume 6 mL/kg decreased PaCO2 by 21% (95% CI, 17-25%), from 47 ± 11 to 37 ± 8 Torr (p < 0.001). Lowering tidal volume to 4 mL/kg reduced minute ventilation from 7.8 ± 1.5 to 5.2 ± 1.1 L/min and plateau pressure from 25 ± 4 to 21 ± 3 cm H2O and raised PaCO2 from 37 ± 8 to 48 ± 10 Torr (all p < 0.001). On an average of both positions, the oxygenator's blood flow was 410 ± 30 mL/min and the CO2 removal rate was 83 ± 20 mL/min. The oxygenator blood flow (p <0.001) and the CO2 removal rate (p = 0.083) were higher when the membrane oxygenator was placed upstream of the hemofilter. There was no safety concern. CONCLUSIONS: Combining extracorporeal CO2 removal and continuous venovenous hemofiltration in patients with acute respiratory distress syndrome and acute kidney injury is safe and allows efficient blood purification together with enhanced lung protective ventilation.

PURPOSE: Takotsubo cardiomyopathy is characterized by the sudden onset of reversible left ventricular dysfunction. Associated refractory cardiogenic shock is a rare occurrence and may require extracorporeal membrane oxygenation (ECMO). We report a case of a patient who, following the inadvertent injection of 1 mg of epinephrine, presented with reverse Takotsubo cardiomyopathy and refractory cardiogenic shock that required the implementation of a percutaneous ECMO. CLINICAL FEATURES: A 49-yr-old female patient presented with reverse Takotsubo cardiomyopathy in the operating room after an inadvertent injection of epinephrine. The development of refractory cardiogenic shock required emergent use of a mobile percutaneous ECMO system. It was possible to wean this support after four days, and the patient was later discharged without cardiac or neurological sequelae. The investigations performed confirmed the iatrogenic nature of this reverse Takotsubo cardiomyopathy. CONCLUSION: Takotsubo cardiomyopathy following an injection of epinephrine remains a rare but increasingly described occurrence. The severity of the symptoms appears to be patient dependent, but refractory cardiogenic shock may occur and require significant circulatory support. If this situation occurs in a hospital where this necessary equipment is lacking, a mobile ECMO unit appears to be a viable solution to optimize the patient's chances of survival.

PURPOSE: Reducing discomfort in the intensive care unit (ICU) should have a positive effect on long-term outcomes. This study assessed whether a tailored multicomponent program for discomfort reduction was effective in reducing post-traumatic stress disorder (PTSD) symptoms at 1 year in general ICU survivors. METHODS: This study is a prospective observational comparative effectiveness cohort study involving 30 ICUs. It was an extension of the IPREA3 study, a cluster-randomized controlled trial designed to assess the efficacy of a tailored multicomponent program to reduce discomfort in critically ill patients. The program included assessment of ICU-related self-perceived discomforts, immediate and monthly feedback to the healthcare team, and site-specific tailored interventions. The exposure was the implementation of this program. The eligible patients were exposed versus unexposed general adult ICU survivors. The prevalence of substantial PTSD symptoms at 1 year was assessed based on the Impact of Event Scale-Revised (IES-R). RESULTS: Of the 1537 ICU survivors included in the study, 475 unexposed patients and 344 exposed patients had follow-up data at 1 year: 57 (12.0%) and 21 (6.1%) presented with PTSD at 1 year, respectively (p = 0.004). Considering the clustering and after adjusting for age, gender, McCabe classification, and ICU-related self-perceived overall discomfort score, exposed patients were significantly less likely than unexposed patients to have substantial PTSD symptoms at 1 year (p = 0.015). CONCLUSIONS: Implementation of a tailored multicomponent program in the ICU that has proved to be effective for reducing self-perceived discomfort in general adult ICU survivors also reduced the prevalence of substantial PTSD symptoms at 1 year.

INTRODUCTION: Rapid detection of abnormal biological values using point-of-care (POC) testing allows clinicians to promptly initiate therapy; however, there are concerns regarding the reliability of POC measurements. We investigated the agreement between the latest generation blood gas analyzer and central laboratory measurements of electrolytes, bicarbonate, hemoglobin, hematocrit, and glucose. METHODS: 314 paired samples were collected prospectively from 51 critically ill patients. All samples were drawn simultaneously in the morning from an arterial line. BD Vacutainer tubes were analyzed in the central laboratory using Beckman Coulter analyzers (AU 5800 and DxH 800). BD Preset 3 ml heparinized-syringes were analyzed immediately in the ICU using the POC Siemens RAPIDPoint 500 blood gas system. We used CLIA proficiency testing criteria to define acceptable analytical performance and interchangeability. RESULTS: Biases, limits of agreement (±1.96 SD) and coefficients of correlation were respectively: 1.3 (-2.2 to 4.8 mmol/L, r = 0.936) for sodium; 0.2 (-0.2 to 0.6 mmol/L, r = 0.944) for potassium; -0.9 (-3.7 to 2 mmol/L, r = 0.967) for chloride; 0.8 (-1.9 to 3.4 mmol/L, r = 0.968) for bicarbonate; -11 (-30 to 9 mg/dL, r = 0.972) for glucose; -0.8 (-1.4 to -0.2 g/dL, r = 0.985) for hemoglobin; and -1.1 (-2.9 to 0.7%, r = 0.981) for hematocrit. All differences were below CLIA cut-off values, except for hemoglobin. CONCLUSIONS: Compared to central Laboratory analyzers, the POC Siemens RAPIDPoint 500 blood gas system satisfied the CLIA criteria of interchangeability for all tested parameters, except for hemoglobin. These results are warranted for our own procedures and devices. Bearing these restrictions, we recommend clinicians to initiate an appropriate therapy based on POC testing without awaiting a control measurement.

PURPOSE: Critically ill patients are exposed to stressful conditions and experience several discomforts. The primary objective was to assess whether a tailored multicomponent program is effective for reducing self-perceived discomfort. METHODS: In a cluster-randomized two-arm parallel trial, 34 French adult intensive care units (ICUs) without planned interventions to reduce discomfort were randomized, 17 to the arm including a 6-month period of program implementation followed by a 6-month period without the program (experimental group), and 17 to the arm with an inversed sequence (control group). The tailored multicomponent program consisted of assessment of ICU-related self-perceived discomforts, immediate and monthly feedback to healthcare teams, and site-specific tailored interventions. The primary outcome was the overall discomfort score derived from the 16-item IPREA questionnaire (0, minimal, 100, maximal overall discomfort) and the secondary outcomes were the discomfort scores of each IPREA item. IPREA was administered on the day of ICU discharge with a considered timeframe from the ICU admission until ICU discharge. RESULTS: During a 1-month assessment period, 398 and 360 patients were included in the experimental group and the control group, respectively. The difference (experimental minus control) of the overall discomfort score between groups was - 7.00 (95% CI - 9.89 to - 4.11, p < 0.001). After adjustment (age, gender, ICU duration, mechanical ventilation duration, and type of admission), the program effect was still positive for the overall discomfort score (difference - 6.35, SE 1.23, p < 0.001) and for 12 out of 16 items. CONCLUSIONS: This tailored multicomponent program decreased self-perceived discomfort in adult critically ill patients. TRIAL REGISTRATION: Clinicaltrials.gov Identifier NCT02442934.

OBJECTIVE: To describe the clinical course and imaging findings in a young man who developed a spongiform leucoencephalopathy from heroin-vapour inhalation, and to discuss the treatments which may have contributed to the unexpected favourable outcome in this case. DESIGN: Case report. SETTING: Intensive care unit of a university teaching hospital. PATIENT: A patient who developed a near fatal toxic leucoencephalopathy with impressive clinical recovery and reversible white matter changes on imaging. MEASUREMENTS AND RESULTS: Successive computed tomography scans and magnetic resonance imaging over 7 months showed evolution from bilateral extensive involvement of the cerebral white matter to almost complete resolution accompanied by the development of periventricular lesions suggestive of necrosis. Despite the fact that the patient had stretching spasms for several days, the outcome was favourable with prolonged supportive care and antioxidant therapy by ubiquinone (coenzyme Q). CONCLUSION: This case demonstrates that prolonged intensive care is of paramount importance in patients with spongiform leucoencephalopathy after inhalation of heated heroin, that abnormalities of cerebral white matter may be slowly regressive, and supports the use of coenzyme Q in severe forms of the disease.

OBJECTIVE: This prospective observational study was undertaken in order to assess pain experienced by intensive care unit patients at the time of extubation and to identify factors associated with pain of at least moderate intensity. DESIGN: Prospective observational study. SETTING: Intensive care unit at a university hospital. PATIENTS: During a 1-year period the presence, severity and clinical predictors of orofacial and/or chest pain among patients undergoing removal of endotracheal tubes was assessed. MEASUREMENTS AND RESULTS: Pain was evaluated using a visual analogue scale (VAS). Of 332 extubated patients, 203 could be evaluated. During the peri-extubation period, pain was significantly associated with a SAPS II score more than 36 ( p=0.03) and duration of mechanical ventilation (MV) of 6 days or more ( p=0.002), whereas intubation in the operating room was associated with less pain ( p=0.001). Pain of at least moderate intensity (VAS score >30 mm) was reported by 73% of patients and pain of severe intensity (VAS score >50 mm) was reported by 45% of patients. MV duration of 6 days or more was the only independent risk factor for pain of at least moderate intensity (OR 2.4, 95% CI 1.03-5.4, p=0.04). We also observed that pain had resolved 1 h after extubation in the majority of patients. CONCLUSION: Our results suggest that, in intensive care unit patients, peri-extubation pain is frequent and should be considered for treatment, especially in patients with longer intubation.

OBJECTIVE: To evaluate the incidence and risks factors of atrial fibrillation (AF). DESIGN: Prospective, observational study. SETTING: A surgical intensive care unit of a university hospital. PATIENTS: All patients with new onset of AF admitted in the surgical intensive care unit during a 6-month period. INTERVENTIONS: None. MEASUREMENT AND MAIN RESULTS: Of the 460 patients included in the study, AF developed in 24 patients (5.3%). According to univariate analysis, age, preexisting cardiovascular disease, and previous treatment by calcium-channel blockers were significant predictors of AF. Patients with AF received significantly more fluids and catecholamines and experienced more sepsis, shock, and acute renal failure. Severity (Simplified Acute Physiologic Score II), intensive care unit workload (OMEGA), intensive care unit and hospital length of stay, and mortality were significantly increased in patients who developed AF. Multivariate analysis identified five independent predictors of AF: advanced age, blunt thoracic trauma, shock, pulmonary artery catheter, and previous treatment by calcium-channel blockers. CONCLUSIONS: In surgical intensive care unit patients, the incidence of AF is greater than in the general population but less than in the cardiac surgery unit. The onset of AF reflects the severity of the disease. Five independent risk factors of AF were identified in surgical intensive care unit patients. The withdrawal of a calcium-channel inhibitor was also an independent risk factor of AF, and the weaning of this treatment must be carefully evaluated. Blunt thoracic trauma increases the chances of developing AF, as does the presence of shock, especially septic shock.
