RESUMO

BACKGROUND: Prior studies have assessed the impact of the pretransplantation recipient body mass index (BMI) on patient outcomes after lung transplantation (LT), but they have not specifically addressed early postoperative complications. Moreover, the impact of donor BMI on these complications has not been evaluated. The first aim of this study was to assess complications during hospitalization in the ICU after LT according to donor and recipient pretransplantation BMI. METHODS: All the recipients who underwent LT at Bichat Claude Bernard Hospital, Paris, between January 2016 and August 2022 were included in this observational retrospective monocentric study. Postoperative complications were analyzed according to recipient and donor BMIs. Univariate and multivariate analyses were also performed. The 90-day and one-year survival rates were studied. P < 0.05 was considered to indicate statistical significance. The Paris-North Hospitals Institutional Review Board approved the study. RESULTS: A total of 304 recipients were analyzed. Being underweight was observed in 41 (13%) recipients, a normal weight in 130 (43%) recipients, and being overweight/obese in 133 (44%) recipients. ECMO support during surgery was significantly more common in the overweight/obese group (p = 0.021), as were respiratory complications (primary graft dysfunction (PGD) (p = 0.006), grade 3 PDG (p = 0.018), neuroblocking agent administration (p = 0.008), prone positioning (p = 0.007)), and KDIGO 3 acute kidney injury (p = 0.036). However, pretransplantation overweight/obese status was not an independent risk factor for 90-day mortality. An overweight or obese donor was associated with a decreased PaO2/FiO2 ratio before organ donation (p < 0.001), without affecting morbidity or mortality after LT. CONCLUSION: Pretransplantation overweight/obesity in recipients is strongly associated with respiratory and renal complications during hospitalization in the ICU after LT.

RESUMO

Background: Only limited pharmacokinetic data are available for anidulafungin in ICU patients, especially in patients treated for severe intra-abdominal infection (IAI). Methods: This was a prospective multicentre observational study in ICU patients with suspected yeast IAI. All patients received an intravenous loading dose of 200 mg of anidulafungin, followed by 100 mg/day. Thirteen blood samples were drawn between day 1 and day 5 for pharmacokinetic analysis. Samples were analysed by an HPLC-tandem MS method. Demographics and SAPS2 and SOFA scores were recorded. Results: Fourteen patients with a median age (IQR) of 62 years (48-70) and with a mean BMI of 30.5 kg/m 2 were included from three centres; 57.1% were women. Their median (IQR) SAPS2 score was 54 (45-67) and their median (IQR) SOFA score was 8 (7-12). Six patients with community-acquired IAI and eight patients with nosocomial-acquired IAI were included. Twelve yeasts were isolated: six Candida albicans , two Candida glabrata , two Candida tropicalis , one Candida parapsilosis and one Candida krusei . Pharmacokinetic parameters were as follows [mean (% coefficient of variation)]: C max (mg/L) = 6.0 (29%); T max (h) = 1.6 (25.8%); C min (mg/L) = 3.2 (36.8%); AUC 0-24 (mg·h/L) = 88.9 (38.6%); t 1/2 (h) = 42.1 (68.2%); CL (L/h) = 1.2 (42.3%); and V (L) = 72.8 (87.8%). A two-compartment model best described the anidulafungin concentrations in the population pharmacokinetic study. Conclusions: The pharmacokinetic parameters of anidulafungin in critically ill ICU patients with complicated IAI are similar to those observed in the literature. However, an increased V and a longer t 1/2 were observed in this study. (EudraCT No. 2010-018695-25).

RESUMO

OBJECTIVES: No recommendations are currently available to help the clinician with the pharmacological management of intensive care unit (ICU) patients with elevated cardiac troponin (cTn) not linked to type 1 AMI. The aim of this study was to evaluate the pattern of cardiologic medications for patients with elevated cTnI in ICU not link to type 1 AMI and their effects on in-hospital mortality. MATERIAL AND METHODS: A prospective observational cohort study conducted in two ICU units. Patients with increased plasma concentration of cTnI at admission not linked to type 1 AMI were consecutively included. RESULTS: One hundred and ninety of the 835 patients admitted (23%) had an increased plasma concentration of cTnI not related to type 1 AMI. Antiplatelet therapy (AT) and statin were prescribed in 56 (29.5%) and 50 (26.3%) of patients, respectively. Others cardiologic medications were prescribed in less than 5% of all cases and were considered as contraindicated in more than 50% of cases. Antiplatelet therapy was the only cardiologic treatment associated with reduction of in-hospital mortality following uni- and multivariate analysis. The death rate was 23% and 40% in these patients treated with and without AT, respectively (aOR=0.39 [95% CI: 0.15-0.97]). CONCLUSIONS: Statin and AT were frequently prescribed to patients with a cTnI elevation not linked to type 1 AMI. This study suggests that AT in patients with an increased plasma concentration of cTnI, not related to type 1 AMI in ICU, could reduce in-hospital mortality.

RESUMO

BACKGROUND: Multidrug-resistant (MDR) bacteria are a growing concern worldwide. The aim of this study was to describe the epidemiology and risk factors of MDR bacteria detected in respiratory invasive samples during hospitalization in the intensive care unit (ICU) after lung transplantation (LT). METHODS: This study was based on a retrospective analysis of 176 patients hospitalized in the ICU after LT in 2006-2012. Respiratory invasive samples were performed according to a routine protocol. MDR pathogens were defined according to in vitro susceptibility tests. RESULTS: A total of 1176 bacteria were cultured. Susceptibility testing was performed on 1046 strains and 404 (39%) MDR were detected in 90 (51%) patients. Pseudomonas aeruginosa, coagulase-negative staphylococci, and Enterobacteriaceae (mainly Enterobacter species) were the most common MDR pathogens. On multivariate analysis, an ICU stay >14 days, presence of a tracheostomy, and previous exposure to broad-spectrum antibiotics were associated with MDR acquisition (odds ratio [OR] 3.7; 95% confidence interval [1.69-8.12]; OR 3.28 [1.05-10.28]; and OR 2.25 [1.17-4.34], respectively). We consistently observed an increasing emergence of resistance to several antibiotics, from week 1 to week 4 of ICU hospitalization: for ticarcillin, piperacillin-tazobactam, ceftazidime, imipenem/cilastatin, amikacin, and ciprofloxacin in P. aeruginosa; and for piperacillin-tazobactam, cefepime, and amikacin in Enterobacteriaceae. CONCLUSION: A large proportion of MDR bacteria are detected on respiratory invasive samples in LT patients, and the risk of their emergence is mainly determined by the previous exposure to broad-spectrum antibiotics and the length of ICU stay. Adequate treatment requires broad-spectrum empiric antibiotic therapy.

RESUMO

In the general population, a history of asthma (HA) is associated with a higher risk of mortality of anaphylactic shock (AS), but it is unknown whether this association remains valid for intra-operative AS. The goal of this retrospective study was to investigate whether a HA was associated with a higher risk of bronchospasm during intra-operative AS. We analyzed 106 patients (January 2009-December 2012) with intra-operative AS: 57% of them had a confirmed IgE-mediated reaction and 27% had a HA. On logistic regression, the only factor statistically associated with bronchospasm was a neuromuscular blocking drug, with both IgE- or non-IgE-mediated reactions. These results suggest that the mechanisms of bronchospasm in AS may be different from those of asthma and that, in the presence of bronchospasm during anesthesia, AS should be considered to be the most likely cause.

RESUMO

Venovenous extracorporeal membrane oxygenation (ECMO) is increasingly used in patients with respiratory failure who fail conventional treatment. Postoperative pneumonia is the most common infection after lung transplantation (40%). Imipenem is frequently used for empirical treatment of nosocomial pneumonia in the intensive care unit. Nevertheless, few data are available on the impact of ECMO on pharmacokinetics, and no data on imipenem dosing during ECMO. Currently, no guidelines exist for antibiotic dosing during ECMO support. We report the cases of 2 patients supported with venovenous ECMO for refractory acute respiratory distress syndrome following single lung transplantation for pulmonary fibrosis, treated empirically with 1 g of imipenem intravenously every 6 h. Enterobacter cloacae was isolated from the respiratory sample of Patient 1 and Klebsiella pneumoniae was isolated from the respiratory sample of Patient 2. Minimum inhibitory concentrations of the 2 isolated strains were 0.125 and 0.25 mg/L, respectively. Both patients were still alive on day 28. This is the first report, to our knowledge, of imipenem concentrations in lung transplantation patients supported with ECMO. This study confirms high variability in imipenem trough concentrations in patients on ECMO and with preserved renal function. An elevated dosing regimen (4 g/24 h) is more likely to optimize drug exposure, and therapeutic drug monitoring is recommended, where available. Population pharmacokinetic studies are indicated to develop evidence-based dosing guidelines for ECMO patients.

RESUMO

BACKGROUND: Respiratory variation in pulse pressure (ΔPP) is commonly used to predict the fluid responsiveness of critically ill patients. However, some researchers have demonstrated that this measurement has several limitations. The present study was designed to evaluate the proportion of patients satisfying criteria for valid application of ΔPP at a given time-point. METHODS: A 1 day, prospective, observational, point-prevalence study was performed in 26 French intensive care units (ICUs). All patients hospitalized in the ICUs on the day of the study were included. The ΔPP validity criteria were recorded prospectively and defined as follows: (i) mechanical ventilation in the absence of spontaneous respiration; (ii) regular cardiac rhythm; (iii) tidal volume ≥8 ml kg(-1) of ideal body weight; (iv) a heart rate/respiratory rate ratio >3.6; (v) total respiratory system compliance ≥30 ml cm H2O(-1); and (vi) tricuspid annular peak systolic velocity ≥0.15 m s(-1). RESULTS: The study included 311 patients with a Simplified Acute Physiology Score II of 41 (39-43). Overall, only six (2%) patients satisfied all validity criteria. Of the 170 patients with an arterial line in place, only five (3%) satisfied the validity criteria. During the 24 h preceding the study time-point, fluid responsiveness was assessed for 79 patients. ΔPP had been used to assess fluid responsiveness in 15 of these cases (19%). CONCLUSIONS: A very low percentage of patients satisfied all criteria for valid use of ΔPP in the evaluation of fluid responsiveness. Physicians must consider limitations to the validity of ΔPP before using this variable.

RESUMO

Recently, an update of the IDSA guidelines for the treatment of complicated intraabdominal infections has been published. No guideline can cater for all variations in ecology, antimicrobial resistance patterns, patient characteristics and presentation, health care and reimbursement systems in many different countries. In the short time the IDSA guidelines have been available, a number of practical clinical issues have been raised by physicians regarding interpretation of the guidelines. The main debatable issues of the new IDSA guidelines are described as follows: The authors of the IDSA guidelines present recommendations for the following subgroups of "complicated" IAI: community-acquired intra-abdominal infections of mild-to-moderate and high severity and health care-associated intra-abdominal infections (no general treatment recommendations, only information about antimicrobial therapy of specific resistant bacterial isolates). From a clinical point of view, "complicated" IAI are better differentiated into primary, secondary (community-acquired and postoperative) and tertiary peritonitis. Those are the clinical presentations of IAI as seen in the emergency room, the general ward and on ICU. Future antibiotic treatment studies of IAI would be more clinically relevant if they included patients in studies for the efficacy and safety of antibiotics for the treatment of the above mentioned forms of IAI, rather than conducting studies based on the vague term "complicated" intra-abdominal infections. - The new IDSA guidelines for the treatment of resistant bacteria fail to mention many of new available drugs, although clinical data for the treatment of "complicated IAI" with new substances exist. Furthermore, treatment recommendations for cIAI caused by VRE are not included. This group of diseases comprises enough patients (i.e. the entire group of postoperative and tertiary peritonitis, recurrent interventions in bile duct surgery or necrotizing pancreatitis) to provide specific recommendations for such antimicrobial treatment. - A panel of European colleagues from surgery, intensive care, clinical microbiology and infectious diseases has developed recommendations based on the above mentioned clinical entities with the aim of providing clear therapeutic recommendations for specific clinical diagnoses. An individual patient-centered approach for this very important group of diseases with a substantial morbidity and mortality is essential for optimal antimicrobial treatment.

RESUMO

INTRODUCTION: The number of lung transplantations performed is increasing worldwide. With an improved experience and outcomes, the age of the recipient on its own has ceased to be an absolute contra-indication. We report our first experience with lung transplantation in patients aged 65 years or older. METHODS: From January 2014 to March 2019, the files of patients aged 65 years or older undergoing lung transplantation were retrospectively reviewed. RESULTS: During the study period, 241 patients underwent lung transplantation in Bichat hospital (Paris, France), including 25 recipients aged 65 years or older. Underlying diagnoses were interstitial (72%) and obstructive (28%) disease. The rate of single lung transplantation was 80%. Sixteen patients required ECMO assistance during the procedure. Early complications were mostly grade III primary graft dysfunction (12%) and cellular rejection (20%). Overall one-year survival rate was 76%. CONCLUSION: After a careful selection of the recipients, the early results of our retrospective single center series are encouraging. We continue to consider lung transplantation in rigorously selected recipients of aged 65 years and more.

RESUMO

BACKGROUND: Colonization pressure is a risk factor for intensive care unit (ICU)-acquired multi-drug-resistant organisms (MDROs). AIM: To measure the long-term respective impact of colonization pressure on ICU-acquired extended-spectrum ß-lactamase-producing Enterobacterales (ESBL-PE) and meticillin-resistant Staphylococcus aureus (MRSA). METHODS: All patients admitted to two ICUs (medical and surgical) between January 1997 and December 2015 were included in this retrospective observational study. Rectal and nasal surveillance cultures were obtained at admission and weekly thereafter. Contact precautions were applied for colonized or infected patients. Colonization pressure was defined as the ratio of the number of MDRO-positive patient-days (PDs) of each MDRO to the total number of PDs. Single-level negative binomial regression models were used to evaluate the incidence of weekly MDRO acquisition. FINDINGS: Among the 23,423 patients included, 2327 (10.0%) and 1422 (6.1%) were colonized with ESBL-PE and MRSA, respectively, including 660 (2.8%) and 351 (1.5%) acquisitions. ESBL-PE acquisition increased from 0.51/1000 patient-exposed days (PEDs) in 1997 to 6.06/1000 PEDs in 2015 (P<0.001). In contrast, MRSA acquisition decreased steadily from 3.75 to 0.08/1000 PEDs (P<0.001). Controlling for period-level covariates, colonization pressure in the previous week was associated with MDRO acquisition for ESBL-PE (P<0.001 and P=0.04 for medical and surgical ICU, respectively), but not for MRSA (P=0.34 and P=0.37 for medical and surgical ICU, respectively). The increase in colonization pressure was significant above 100/1000 PDs for ESBL-PE. CONCLUSION: Colonization pressure contributed to the increasing incidence of ESBL-PE but not MRSA. This study suggests that preventive control measures should be customized to MDROs.

RESUMO

BACKGROUND: Acute kidney injury (AKI) is associated with increased short-term and long-term mortality and morbidity after lung transplantation (LT). The primary objective of this study was to analyze the perioperative factors associated with AKI according to Kidney Disease: Improving Global Outcome (KDIGO) criteria during hospitalization in an intensive care unit (ICU) after LT. METHODS: This was a single-center, observational, prospective study. AKI was defined according to KDIGO criteria. Results are expressed as median, interquartile range, absolute numbers, and percentages. Statistical analyses were performed using χ2 test, Fisher exact test, and Mann-Whitney U test. P < .05 was considered to be significant. Multivariate analysis was performed to identify independent risk factors. RESULTS: Between January 2016 and April 2018, 94 patients underwent LT (70% bilateral LT). AKI occurred during ICU stay in 46 patients (49%). KDIGO 1 AKI was observed in 16 patients (17%), KDIGO 2 in 14 patients (15%), and KDIGO 3 in 16 patients (17%), including 12 patients (75%) who required renal replacement therapy. AKI occurred before the fifth day after surgery for 38 patients (82% of the AKI patients). On multivariate analysis, independent factors associated with AKI were bilateral LT and mechanical ventilation >3 days (odds ratio [OR] 4.26, 95% confidence interval [CI] [1.49; 13.63] P = .010 and OR 5.56 [1.25; 11.47] P = .018, respectively). AKI and the need for renal replacement therapy were significantly associated with ICU mortality, 28-day mortality, and 1-year mortality. CONCLUSION: AKI is common during ICU stay after LT, especially after bilateral LT, and is associated with prolonged mechanical ventilation and increased short-term and long-term mortality.

RESUMO

BACKGROUND: Fungus-positive respiratory samples (FPRS) are common in the intensive Care unit (ICU) and are usually considered to correspond to colonization. The management of FPRS during the early postoperative course after lung transplantation (LT) remains unclear. The epidemiology, clinical consequences, and prognosis of FPRS were assessed in LT recipients. METHODS: Over a 6-year period, we analyzed the postoperative ICU course of 176 LT recipients with a specific focus on microbiological results of routine respiratory samples and clinical course. The outcomes during the ICU stay at day 28 and at 1 year were compared in patients with or without FPRS. Results are expressed as median and interquartile range. RESULTS: In the pretransplantation period, Candida spp were reported in 17% of patients. No routine post-LT antifungal prophylaxis was initiated. In the post-LT period, at least 1 FPRS was observed in 69% of patients (93% Candida spp, 7% Aspergillus spp). Double LT (odds ratio = 4.15, 95% confidence interval [1.67-11.80], P = .0007) was the only risk factor associated with Candida spp in respiratory samples. Antifungal therapy was administered in 58% of patients with post-LT Candida-positive samples. Candida spp in post-LT respiratory samples were not associated with increased ICU, 28-day, or 1-year mortality rates. CONCLUSION: A high prevalence of FPRS is reported after LT, mainly with Candida spp. The lack of association between post-LT FPRS and mortality and morbidity suggests avoiding antifungal therapy in the absence of clinical signs of invasive infection.

RESUMO

Infection is a risk for any intervention. In surgery, for example, pathogenic bacteria are found in more than 90% of operative wounds during closure. This exists whatever the surgical technique and whatever the environment (the laminar flow does not entirely eliminate this risk). These bacteria are few in number but can proliferate. They find in the operative wound a favourable environment (haematoma, ischaemia, modification of oxido-reduction potential...) and the intervention induces anomalies of the immune defences. In the case of the installation of foreign material, the risk is increased. The objective of antibiotic prophylaxis (ABP) is to prevent bacterial growth in order to reduce the risk of infection at the site of the intervention. The preoperative consultation represents a privileged moment to decide on the prescription of a ABP. It is possible to define the type of intervention planned, the associated risk of infection (and therefore the necessity or not of ABP), the time of prescription before surgery and any allergic antecedents which may modify the choice of the selected antibiotic molecule.

RESUMO

The influenza pandemic will create a major increase in demand for hospital admissions, particularly for critical care services. The recommendations detailed herein have been elaborated by experts from medical societies potentially involved in this situation and focus on general hospital organization. Intensive care units will initially face high demand for admission; the Healthcare Authorities must therefore study how ICU capacity can be expanded. Pediatric intensive care units will be particularly affected by this situation of relative bed shortage, since young children, particularly infants, are expected to be affected by severe clinical forms of avian flu. Therefore, the weight threshold for admission to the adult ICU was lowered to 20 kg. Neonatal intensive care units (NICU) should remain, if possible, low viral density areas. Mixed (neonatal and pediatric) intensive care units could be dedicated to infants and children only. NICU admission of extreme premature babies should be limited in this difficult situation. Pediatric intensive care units (PICU) admission capacity could be doubled by using intermediate care and postoperative care units. The staff could be increased by doctors and nurses involved in canceled programmed activities. Healthcare workers transferred to PICU should be given special training.

RESUMO

The development of an epidemic of avian influenza will have a major impact on the organisation and structure of the facilities for treatment. This paper, the product of collaboration between the six learned societies concerned, analyses the impact of a possible pandemic on the various aspects of management of patients requiring intensive care. It describes the organisation of hospital pathways for flu and non-flu patients with, in particular, the necessary actions in terms of separation of care facilities, the triage of patients and the cancellation of non-urgent activities. It analyses the preconditions necessary for the efficient functioning of intensive care and the predictable limiting factors. It underlines the importance of training of medical and paramedical personnel. Finally, it tackles the specific problems of paediatric intensive care: organisation, capacity for admissions and training.

RESUMO

BACKGROUND: In pregnancy, airway oedema and heartburn may increase cough sensitivity, whereas spinal anaesthesia (SA) with local anaesthetics and opiates may decrease it. Decreased cough sensitivity increases the risk for pneumonia or retained secretions. The aim of this study was to determine whether cough sensitivity is increased in pregnant patients and if it is decreased after planned Caesarean section (CS) under SA. METHODS: Twenty-seven non-pregnant volunteers, 27 patients after vaginal delivery (VD group), and 28 patients after CS under SA (CS group) were studied. For SA, hyperbaric bupivacaine 8-12 mg, sufentanil 5 microg, and morphine 100 microg was given. Increasing concentrations of nebulized citric acid were delivered until eliciting cough. The concentration eliciting one (C1) and two coughs (C2) were recorded and log transformed for analysis (log C1 and log C2). RESULTS: Median (inter-quartile) log C1 was 1.3 (0.6) mg ml(-1) in the VD group, 1.6 (0.6) mg ml(-1) in the non-pregnant group (P < 0.01 vs VD group), and 2.2 (0.7) mg ml(-1) in the CS group (P < 0.0001 and P < 0.01 vs VD and non-pregnant groups, respectively). Similar results were observed with log C2. In CS group, log C1 and log C2 remained increased up to 4 h after SA. CONCLUSIONS: Cough sensitivity was increased after VD but decreased for up to 4 h after SA.

RESUMO

OBJECTIVE: The clinical characteristics and prognosis of patients treated for Candida peritonitis (CP) were compared according to the type of systemic antifungal therapy (SAT), empiric (EAF) or targeted (TAF) therapies, and the final diagnosis of infection. METHODS: Patients in intensive care units (ICU) treated for CP were selected among the AmarCAND2 cohort, to compare patients receiving EAF for unconfirmed suspicion of CP (EAF/nonCP), to those with suspected secondarily confirmed CP (EAF/CP), or with primarily proven CP receiving TAF. RESULTS: In all, 279 patients were evaluated (43.4% EAF/nonCP, 29.7% EAF/CP and 25.8% TAF patients). At SAT initiation, the severity of illness was similar among EAF/nonCP and EAF/CP patients, lower among TAF patients (median Simplified Acute Physiology Score II (SAPS II) 49 and 51 versus 35, respectively; p 0.001). Candida albicans was involved in 67%, Candida glabrata in 15.6%. All strains were susceptible to echinocandin; 84% to fluconazole. Echinocandin was administered to 51.2% EAF/nonCP, 49% EAF/CP and 40% TAF patients. At day 28, 72%, 76% and 75% of EAF/nonCP, EAF/CP and TAF patients, respectively, were alive. An increased mortality was observed in patients with a Sequential Organ Failure Assessment (SOFA) score <7 if SAT was delayed by ≥6 days (p 0.04). Healthcare-associated CP (OR 3.82, 95% CI 1.52-9.64, p 0.004), SOFA ≥8 at ICU admission (OR 2.61, 95% CI 1.08-6.34; p 0.03), and SAPS II ≥45 at SAT initiation (OR 5.08, 95% CI 1.04-12.67; p 0.001) impacted the 28-day mortality. CONCLUSIONS: In summary, only 56.6% of ICU patients receiving SAT had CP. Most strains were susceptible to SAT. A similar 28-day mortality rate was observed among groups; the late administration of SAT significantly worsened the prognosis of patients with less severe CP.
