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.

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.

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
PURPOSE: The management of peritonitis in critically ill patients is becoming increasingly complex due to their changing characteristics and the growing prevalence of multidrug-resistant (MDR) bacteria. METHODS: A multidisciplinary panel summarizes the latest advances in the therapeutic management of these critically ill patients. RESULTS: Appendicitis, cholecystitis and bowel perforation represent the majority of all community-acquired infections, while most cases of healthcare-associated infections occur following suture leaks and/or bowel perforation. The micro-organisms involved include a spectrum of Gram-positive and Gram-negative bacteria, as well as anaerobes and fungi. Healthcare-associated infections are associated with an increased likelihood of MDR pathogens. The key elements for success are early and optimal source control and adequate surgery and appropriate antibiotic therapy. Drainage, debridement, abdominal cleansing, irrigation, and control of the source of contamination are the major steps to ensure source control. In life-threatening situations, a "damage control" approach is the safest way to gain time and achieve stability. The initial empirical antiinfective therapy should be prescribed rapidly and must target all of the micro-organisms likely to be involved, including MDR bacteria and fungi, on the basis of the suspected risk factors. Dosage adjustment needs to be based on pharmacokinetic parameters. Supportive care includes pain management, optimization of ventilation, haemodynamic and fluid monitoring, improvement of renal function, nutrition and anticoagulation. CONCLUSIONS: The majority of patients with peritonitis develop complications, including worsening of pre-existing organ dysfunction, surgical complications and healthcare-associated infections. The probability of postoperative complications must be taken into account in the decision-making process prior to surgery.

Postoperative peritonitis (POP) is a common surgical complication after bariatric surgery (BS). We assessed the importance of positive fungal cultures in these cases of POP admitted to the intensive care unit. Clinical features and outcome were compared in 25 (41%) Candida-positive patients (6 (22%) fluconazole-resistant Candida glabrata) and 36 patients without Candida infection. Candida infections were more commonly isolated in late-onset peritonitis and were often associated with multidrug-resistant bacteria. Risk factors for intensive care unit mortality (19.6%) were diabetes and superobesity. Candida infections, including fluconazole-resistant strains, are common in POP after BS. These data encourage the empirical use of a broad-spectrum antifungal agent.

A prospective, multicentre, phase IIIb study with an exploratory, open-label design was conducted to evaluate efficacy and safety of anidulafungin for the treatment of candidaemia/invasive candidiasis (C/IC) in specific ICU patient populations. Adult ICU patients with confirmed C/IC meeting ≥ 1 of the following criteria were enrolled: post-abdominal surgery, solid tumour, renal/hepatic insufficiency, solid organ transplant, neutropaenia, and age ≥ 65 years. Patients received anidulafungin (200 mg on day 1, 100 mg/day thereafter) for 10-42 days, optionally followed by oral voriconazole/fluconazole. The primary efficacy endpoint was global (clinical and microbiological) response at the end of all therapy (EOT). Secondary endpoints included global response at the end of intravenous therapy (EOIVT) and at 2 and 6 weeks post-EOT, survival at day 90, and incidence of adverse events (AEs). The primary efficacy analysis was performed in the modified intent-to-treat (MITT) population, excluding unknown/missing responses. The safety and MITT populations consisted of 216 and 170 patients, respectively. The most common pathogens were Candida albicans (55.9%), C. glabrata (14.7%) and C. parapsilosis (10.0%). Global success was 69.5% (107/154; 95% CI, 61.6-76.6) at EOT, 70.7% (111/157) at EOIVT, 60.2% (77/128) at 2 weeks post-EOT, and 50.5% (55/109) at 6 weeks post-EOT. When unknown/missing responses were included as failures, the respective success rates were 62.9%, 65.3%, 45.3% and 32.4%. Survival at day 90 was 53.8%. Treatment-related AEs occurred in 33/216 (15.3%) patients, four (1.9%) of whom had serious AEs. Anidulafungin was effective, safe and well tolerated for the treatment of C/IC in selected groups of ICU patients.

BACKGROUND: Chronic stress during pregnancy has been associated with worsened maternal and fetal outcomes. Acute stress immediately before spinal anaesthesia for caesarean section may contribute to hypotension. Therefore objective measures of acute stress may help identify women at risk of adverse outcomes. Salivary alpha-amylase is a stress biomarker that has so far been poorly investigated during pregnancy. The reference change value is the difference between two sequential results that must be exceeded for a change to be considered clinically relevant. Our first aim was to determine if salivary alpha-amylase increased in pregnant patients when subjected to the stress of transfer to the operating room. Our second aim was to determine if changes in salivary alpha-amylase were likely to be clinically significant by measuring reference change value in healthy volunteers. METHODS: In 15 pregnant patients undergoing planned caesarean section under spinal anaesthesia, salivary alpha-amylase, systolic blood pressure, heart rate, and immediate anxiety were measured on the morning of surgery on the ward and again in the operating room. The reference change value was calculated from 18 healthy volunteers. RESULTS: A median 220% increase in salivary alpha-amylase activity (P=0.0015) and a 17% increase in systolic blood pressure (P=0.0006) were observed between the ward and operating room. No changes of immediate anxiety or heart rate were observed. Reference change value was ±76% in volunteers and 13 of the 15 pregnant patients had a salivary alpha-amylase increase greater than the reference change value. CONCLUSION: When pregnant women are taken to the operating room, a clinically and statistically significant increase in salivary alpha-amylase was observed. Further studies are required to define its clinical usefulness.

OBJECTIVE: To describe the perioperative management, from the point of view of the anesthesia-intensive care unit specialist, of patients with aortic stenosis who undergo transcatheter aortic valve implantation (femoral or apical TAVI). DATA SOURCE: The PubMed database (http://www.ncbi.nlm.nih.gov/entrez/query.fcgi) was queried, using the following keywords: aortic stenosis, transcatheter aortic valve implantation TAVI, outcome, complications, anesthesia. DATA SYNTHESIS: TAVI is performed in patients suffering from aortic stenosis and presenting with numerous comorbidities, high-predicted perioperative mortality and/or contraindications to conventional cardiac surgery. TAVI is performed either by percutaneous transfemoral or transapical puncture of the left ventricle (LV) apex. These patients are older, have more comorbidities than those undergoing aortic valve replacement surgery and perioperative mortality predicted by risk scores is higher. While transapical TAVI is performed with general anaesthesia, transfemoral TAVI can be performed with either general or locoregional anaesthesia and/or sedation. The choice of the anaesthetic technique for transfemoral TAVI depends on the patient's medical history, the technique chosen for valve implantation, the type of monitoring and the anticipated hemodynamic problems. The incidence of complications following TAVI is high, some are common to surgical aortic valve replacement, and others are specific to this technique. Because of the prevalence of comorbidities, the hemodynamic-specific constraints of this technique and the incidence of complications, anaesthetic and perioperative management (evaluation, anaesthetic technique, monitoring, post-surgery care) requires the same level of expertise as in cardiac surgery anaesthesia. CONCLUSION: TAVI expands treatment options for patients with aortic valve stenosis. The anaesthesia team must be involved in the care of these patients with the same level of expertise and care as in heart surgery on critical patients.

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.

OBJECTIVE: To evaluate the practice concerning the iron prescription by French intensivists. TYPE OF STUDY: Survey during an intensive care-national congress. METHODS: Interviewed practitioners were separated in two groups (prescribing [P] iron once time or more per week; or not [NP] less than one time per month). Iron-treatments (iv or oral) efficacy and tolerance were quoted from 1 to 10. RESULTS: All the 128 interviewed intensivists (73% male; mean age 36+/-8 years) considered having anaemic patients and 94% considered having patients with iron deficiency. For 72% of them, the iron deficiency was judged frequent (concerning >10% of their patients) and 25% were P. Intravenous iron, oral iron or both were used by, respectively, 20, 35 and 44% of the interviewed intensivists. Intravenous iron was considered more efficient (7+/-2 versus 6+/-2; p<0.001) and better tolerated (7+/-2 versus 6+/-2; p<0.001) than oral iron. There was no demographic difference between P and NP. P answered more often having patients with iron deficiency (p=0.04), but they did not perform biological tests for diagnosis of iron deficiency more often and did not consider iron-treatment efficacy or tolerance higher than NP. CONCLUSION: Intensive-care anaemia and iron deficiency were considered to be frequent and iron treatments to be efficient and quite well tolerated. But only 25% of the interviewed intensivists were frequent-iron prescribers. This survey underscore that iron prescription in ICU seems to rely more on clinical feeling than on strong evidence: it's time to investigate!

A large number of immunomodulatory therapies has been evaluated in patients with severe sepsis and septic shock. Until recently, none of these treatments has ever demonstrated any benefit in terms of decreased mortality. Many biases could interfere with the results of these clinical trials linked to poor comprehension of immune response, pharmacological errors, selection bias, and mistakes in the evaluation of the patients and in the interpretation of the results. Based on these methodological flaws, the authors try to define directions for future clinical trials.

Fournier's gangrene is a necrotizing infection of skin and soft tissue of the perineum. Several sources of contamination have been described: cutaneous, urological or anorectal. Anatomy of the perineum helps in the prediction of the extension of the infection. The bacterial flora (usually mixed aero-anaerobic flora) depends on the source of infection: gram-positive cocci (skin source) combined with gram-negative bacilli and anaerobes (urological or anorectal source). CT scan and echography are useful tools for the diagnosis without delaying surgery. In the diagnostic procedure and the management, proctological examination, retrograde uretrography, bowel and urine derivation should be discussed.

Beside conventional therapy, the management of necrotizing cellulitis and fasciitis is based on non-pharmacological treatments. Hyperbaric oxygen therapy and dressings are the most frequently used techniques. The usefulness of hyperbaric oxygen therapy is clearly demonstrated in experimental studies while the efficacy of this technique is poorly assessed in clinical practice. The French consensus conference has concluded to an adjuvant role of hyperbaric oxygen therapy combined to intensive care management, surgery and antibiotic therapy. Occlusive conventional dressings using humid or vaseline gauze dressings are largely used. Calcium alginate or silver coated dressings might be useful. In addition, vacuum-assisted closure therapy could be proposed in replacement of conventional dressings.

The incidence of the haemophagocytic syndrome in the ICU patients with multiple organ failure seems to be high. The haemophagocytic syndrome can be considered as the consequence of the initial aggression leading to multiple organ failure. On the contrary the haemophagocytic syndrome could be the cause of multiple organ failure. A case of haemophagocytic syndrome is presented which led to rapidly fatal multiple organ failure.

OBJECTIVE: The risk of cross infection due to non-conventional infectious agents has led to the development of single-use disposable medical material. For laryngoscopy, two attitudes have been proposed: the use of disposable blades or disposable translucide cover sheaths with steel blades. Practice studies assessing the quality of these devices are scarce, leaving the physician to his own experience. STUDY DESIGN: Open pilot study assessing satisfaction of the users during tracheal intubation. PATIENTS AND METHODS: Hundred patients of general surgery requiring tracheal intubation underwent laryngoscopy in routine condition with disposable blades (Penlon Crystal) or disposable cover sheaths (Penlon Lary Gard) with steel blades. The users gave a general appreciation of the device and specific comments on the easiness of insertion of the blade, intensity of light and its focus, quality of glottic exposure, easiness of tracheal tube insertion, and solidity of the device. RESULTS: With both devices, intubation was impossible in 6% of the patients. The users considered that intubation was performed in comfortable conditions with both devices. Dim light was noticed with Crystal blade. CONCLUSION: In case of use of disposable material, both devices seem to be close in terms of quality of intubation.

OBJECTIVE: The isolation of Candida sp in nosocomial infections is on the increase and over the past 10 years many guidelines for "good" practices and recommendations have been published on the modalities for the management of systemic candidiasis. The aim of this paper was to assess the habits in the intensive care units in this domain in France. METHOD: A transversal survey on the habits was conducted from March to May 2001, using a questionnaire mailed to 200 intensive care units. RESULTS: One hundred eighty questionnaires (surgical reanimation: 12%, medical: 18%, medico-surgical: 70%) out of 200 (92.5%) were returned. The indirect diagnostic examinations: serology, search for antigenemia and PCR (Polymerase Chain Reaction) were never used in 21, 35 and 65% of cases. The systematic search for colonisation (a mean of 4 areas sampled) was conducted in all the patients by 19% of the investigators, in some patients by 53%, and never by 28%. An antifungal treatment was prescribed: in the presence of a positive haemoculture alone, once out of twice if the sample had been taken from a central catheter and in 2 cases out of 3 when the sample was peripheral. It was prescribed 6 times out of 10 after isolation of Candida sp following surgery or on needle aspiration of an intra-abdominal abscess, varyingly in the case of cadiduria, isolation of a Candida sp in a broncho-pulmonary sample or in abdominal draining and positive culture of a catheter, depending on the intensity of the colonisation, the severity of the clinical picture and the presence of factors of risk for Candida infection. It is still prescribed empirically depending on the same elements and the absence of explanation for worsening. When faced with candidemia in a non-neutropenic patient, a central catheter is not changed in 18% of cases. Depending on the microbiology, fluconazole is prescribed in: the identification of yeast without further precision (78% of cases), Candida sp without further precision (86% of cases), Candida non albicans without further precision (57% of cases), C. albicans (93% of cases), Candida non albicans other than C. krusei and C. glabrata (62% of cases), C. glabrata (36% of cases) with an increase in dose in 1 out of 2 cases. In the presence of C. glabrata or C. krusei, amphotericin B is the choice in respectively 51 and 75% of cases. To adapt the treatment.

The relationship between virulence and chromosomal elements containing glycopeptide resistance genes was experimentally assessed for two transconjugant strains of Enterococcus faecalis (VanA and VanB phenotypes) and compared to that for a susceptible wild-type strain. Microbiologic and inflammatory effects were assessed in a polymicrobial rat model of peritonitis. Mean peritoneal enterococcus concentrations +/- standard deviations at day 1 were 2.1 +/- 1.9, 1.3 +/- 1.1, and 1.7 +/- 2.0 log(10) CFU/ml for susceptible, VanA, and VanB strains, respectively (P < 0.05). At day 3 also there were lower concentrations of glycopeptide-resistant enterococcal strains in peritoneal fluid (3.2 +/- 3.4, 1.8 +/- 1.8, and 2.1 +/- 2.4 log(10) CFU/ml for susceptible, VanA, and VanB strains, respectively [P < 0.05]). Transconjugant glycopeptide-resistant strains were associated with increased peritoneal cell counts at the different evaluation times of the experiment (P < 0.001). Plasma alpha1-acid glycoprotein concentrations were lower in the presence of the susceptible strain (667 +/- 189 mg/liter) than in the presence of the VanA or VanB strain (1,193 +/- 419 or 1,210 +/- 404 mg/liter, respectively [P < 0.05]), while concentrations of tumor necrosis factor alpha and interleukin-6 in peritoneal fluid remained similar for the strains. These results suggest a trend toward variation of virulence of transconjugant strains compared to the wild-type strain in this peritonitis model.
