RESUMEN
BACKGROUND: Although Patient Blood Management (PBM) is recommended by international guidelines, little evidence of its effectiveness exists in abdominal surgery. The aim of this study was to evaluate the benefits of the implementation of a PBM protocol on transfusion incidence and anaemia-related outcomes in major urological and visceral surgery. METHODS: In this before-after study, a three-pillar PBM protocol was implemented in 2020-2021 in a tertiary care centre, including preoperative correction of iron-deficiency anaemia, intraoperative tranexamic acid administration, and postoperative restrictive transfusion. A historical cohort (2019) was compared to a prospective cohort (2022) after the implementation of the PBM protocol. The primary outcome was the incidence of red blood cell transfusion intraoperatively or within 7 days after surgery. RESULTS: Data from 488 patients in the historical cohort were compared to 499 patients in the prospective cohort. Between 2019 and 2022, screening for iron deficiency increased from 13.9% to 69.8% (p < 0.01), tranexamic acid administration increased from 9.5% to 84.6% (p < 0.01), and median haemoglobin concentration before transfusion decreased from 77 g.L-1 to 71 g.L-1 (p = 0.02). The incidence of red blood cell transfusion decreased from 11.5% in 2019 to 6.6% in 2022 (relative risk 0.58, 95% CI 0.38-0.87, p = 0.01). The incidence of haemoglobin concentration lower than 100 g.L-1 at discharge was 24.2% in 2019 and 21.8% in 2022 (p = 0.41). The incidence of medical complications was comparable between the groups. CONCLUSION: The implementation of a PBM protocol over a two-year period was associated with a reduction of transfusion in major urological and visceral surgery.

OBJECTIVES: The objectives were to analyze the evolution of the postoperative bleeding after coronary artery bypass grafting and to determine which factors impacted on this evolution. METHODS: This is a single-center retrospective study including 4590 patients undergoing coronary bypass surgery between 1995 and 2017. The study period was divided into 3 same-sized periods. We analyzed the evolution of the bleeding according to: the chest volume bleeding over the first 24hours, the severity and the rate of transfusion during the hospital stay. Intrahospital outcomes were compared between "minor" and "major" bleedings. The risk factors of major bleeding were analyzed by multiple logistic regression. RESULTS: The chest volume decreased particularly during the first years of the study period. Major bleedings decreased over the periods (7.3%, 4.9% and 3.8% respectively, P<0.0001), as did the rate of transfusion (26.4%, 23.5% and 19.6% respectively, P<0.0001). Major bleedings were correlated with hospital mortality (8.2% versus 1.1%, P<0.0001). The risk factors of major bleeding were the period 1 (1995 to 2003), a renal failure, a resternotomy, the EuroSCORE, the hematocrit prior to cardiopulmonary bypass and the duration of cardiopulmonary bypass. CONCLUSIONS: Postoperative bleeding decreased mainly in the 1990s. Progressive changes in bleeding prevention and blood recovery, surgical techniques, haemoglobin threshold for transfusion decision and practitioners' experience have contributed to these results and must be continued to optimize the postoperative outcomes.

Background Operating rooms and Intensive Care Units are places where an optimal management of drugs and medical devices is required. Objective To evaluate the impact of a dedicated pharmacist in an academic Anaesthesiology and Critical Care Department. Setting This study was conducted in the Anaesthesiology and Critical Care Department of Grenoble University Hospital. Method Between November 2013 and June 2017, the drug-related problems occurring in three Intensive Care Units and their corrections by a full-time clinical pharmacist were analyzed using a structured order review instrument. Pharmaceutical costs in the Anaesthesiology and Critical Care Department were analyzed over a 7 year period (2010-2016), during which automated dispensing systems and recurrent meetings to review indications of medications and medical devices were implemented in the department. Main outcome measure Analysis of two issues: correcting drug-related problems and containing pharmaceutical costs. Results A total of 324 drug-related problems were identified. The most frequent problem concerned anti-infective agents (45%), and this was mainly due to the over-dosage of drugs (30%). Dosage adjustments were the most frequent interventions performed by the pharmacist (43%). Over the 7 year period, pharmaceutical costs decreased by 9% (365,469), while the care activity of the department increased by 55% (+ 12,022 surgical procedures and + 1424 admissions in the ICU). Conclusion Integrating a pharmacist into the Anaesthesiology and Critical Care Department was associated with interventions to correct drug-related problems and containing pharmaceutical costs. Pharmacists should play a central role in such medical environments, to optimize the use of drugs and medical devices.

BACKGROUND: Head-to-head comparisons of combinations of more than one non-opioid analgesic (NOA) with morphine alone, for postoperative analgesia, are lacking. The objective of this multicentre, randomised, double-blind controlled trial was to compare the morphine-sparing effects of different combinations of three NOAs-paracetamol (P), nefopam (N), and ketoprofen (K)-for postoperative analgesia. METHODS: Patients from 10 hospitals were randomised to one of eight groups: control (C) received saline as placebo, P, N, K, PN, PK, NK, and PNK. Treatments were given intravenously four times a day during the first 48 h after surgery, and morphine patient-controlled analgesia was used as rescue analgesia. The outcome measures were morphine consumption, pain scores, and morphine-related side-effects evaluated 24 and 48 h after surgery. RESULTS: Two hundred and thirty-seven patients undergoing a major surgical procedure were included between July 2013 and November 2016. Despite a failure to reach a calculated sample size, 24 h morphine consumption [median (inter-quartile range)] was significantly reduced in the PNK group [5 (1-11) mg] compared with either the C group [27 (11-42) mg; P<0.05] or the N group [21 (12-29) mg; P<0.05]. Results were similar 48 h after surgery. Patients experienced less pain in the PNK group compared with the C, N, and P groups. No difference was observed in the incidence of morphine-related side-effects. CONCLUSIONS: Combining three NOAs with morphine allows a significant morphine sparing for 48 h after surgery associated with superior analgesia the first 24 h when compared with morphine alone. CLINICAL TRIAL REGISTRATION: EudraCT: 2012-004219-30; NCT01882530.

Following cardiac surgery, hyperlactatemia due to anaerobic metabolism is associated with an increase in both morbidity and mortality. We previously found that an elevated respiratory quotient (RQ) predicts anaerobic metabolism. In the present study we aimed to demonstrate that it is also associated with poor outcome following cardiac surgery. This single institution, prospective, observational study includes all those patients that were consecutively admitted to the intensive care unit (ICU) after cardiac surgery with cardiopulmonary bypass, that had also been monitored using pulmonary artery catheter. Data were recorded at admission (H0) and after one hour (H1) including: oxygen consumption ([Formula: see text]), carbon dioxide production ([Formula: see text]), RQ ([Formula: see text]), lactate levels and mixed venous oxygen saturation ([Formula: see text]). The primary endpoint was defined as mortality at 30 days. Comparison of the area under the curve (AUC) for receiver operating characteristic curves was used to analyze the prognostic predictive value of RQ, lactate levels and [Formula: see text], in terms of patient outcome. We studied 151 patients admitted to the ICU between May 2015 and February 2016. Seventy eight patients experienced a worse than expected outcome in the post-operative period, and among those seven died. RQ at H1 in non-survivors ([Formula: see text]) was higher than in survivors ([Formula: see text]; p = 0.02). The AUC for RQ to predict mortality was 0.77 (IC95% [0.70-0.84]), with a threshold value of 0.76 (sensitivity 64%, specificity 100%). By comparison, the AUC for lactate levels was significantly superior (AUClact 0.89, IC95% [0.83-0.93], p = 0.02). In this study, elevated RQ appeared to be predictive of mortality after cardiac surgery with CPB.

Through this series of four closed claims, we highlight examples of accidents stemming from poor ventilator use. We then review the main issues in this regard as reported in the literature and by learned societies. This case series has led us to emphasise the need for safety procedures involving systematic checks prior to use, declaration and analysis of the risk, as well as feedback and teaching regarding ventilation systems.

The French Working Group on Perioperative Haemostasis (GIHP) and the French Study Group on Haemostasis and Thrombosis (GFHT) in collaboration with the French Society of Anaesthesia and Intensive Care Medicine (SFAR) drafted up-to-date proposals on the management of antiplatelet therapy for non-elective invasive procedures or bleeding complications. The proposals were discussed and validated by a vote; all proposals could be assigned with a high strength. Emergency management of oral antiplatelet agents (APA) requires knowledge on their pharmacokinetic/pharmacodynamics parameters, evaluation of the degree of the alteration of haemostatic competence and the associated bleeding risk. Platelet function testing may be considered. When APA-induced bleeding risk may worsen the prognosis, measures should be taken to neutralise antiplatelet therapy by considering not only the efficacy of available means (which can be limited for prasugrel and even more for ticagrelor) but also the risks that these means expose the patient to. The measures include platelet transfusion at the appropriate dose and haemostatic agents (tranexamic acid; rFVIIa for ticagrelor). When possible, postponing non-elective invasive procedures at least for a few hours until the elimination of the active compound (which could compromise the effect of transfused platelets) or if possible a few days (reduction of the effect of APA) should be considered.

BACKGROUND: Patients on either antiplatelet or anticoagulant therapy may need procedures performed under peripheral nerve blocks in preference to general anaesthesia techniques. The risk of bleeding associated with peripheral nerve blocks under these circumstances remains unknown. This systematic review evaluates the incidence of bleeding complications following peripheral nerve blocks in patients receiving antiplatelet and/or anticoagulant medication. METHOD: All English, French and Spanish publications on peripheral nerve blocks in patients receiving antiplatelet and/or anticoagulant medication, from 1978 to 2018 from various sources including Pubmed, were reviewed. Publications on neuraxial anaesthesia (spinal or epidural) and eye blocks were excluded. RESULTS: Twenty-four articles were selected, including six observational studies and 18 case reports. Patients received antiplatelet agents only, in 4 studies, anticoagulants only in 14 studies, and both in 6 studies. In the observational studies, 80 bleeding complications (haematoma or minor bleeding at the puncture site) were identified following 9738 peripheral nerve blocks. Amongst case reports, 15 bleeding complications were noted following 50 peripheral nerve blocks. Bleeding complications were reported mostly with lumbar plexus blocks (1 requirement for blood transfusion, 1 catheter embolization, 1 surgical exploration and 1 death). The overall estimate of the incidence of bleeding complications was 0.82% (0.64%-1.0%). CONCLUSION: This systematic review found that bleeding complications following peripheral nerve blocks were rare in patients receiving antiplatelet and/or anticoagulant medication.

Massive pulmonary embolism is a leading cause of death during pregnancy. While the prevention of thromboembolic disease during the peripartum period is codified, there is no consensus regarding its treatment. We report two cases of pregnant women who had massive pulmonary embolisms (PE) and shock treated with veno-arterial extracorporeal life support (ECLS) and heparin therapy.Haemodynamic and oxygenation parameters were rapidly restored. The patients completely recovered and the pregnancies continued. The patients did not develop pulmonary hypertension. ECLS can be considered as a successful treatment option of massive pulmonary embolism during pregnancy.

Three new Direct Oral Anticoagulants (DOACs), rivaroxaban, apixaban and dabigatran etexilate are available on the French market. Management of DOAC-induced bleeding risk remains challenging. For elective procedures with high hemorrhagic risk, a last DOAC intake five days before procedure ensures complete elimination in all patients. Heparin bridging therapy should be proposed only to patients at high thrombotic risk. For elective procedures with low hemorrhagic risk, the DOAC intake of the night before procedure should be omitted. For urgent procedures with high bleeding risk, DOAC plasmatic concentration can be helpful: concentration lower than 30 ng/mL should enable performing the procedure; a high concentration is associated with a higher bleeding risk, especially if higher than 400 ng/mL. In case of massive bleeding, no antidote is approved yet; activated prothrombin concentrates or non-activated 4-factors prothrombin concentrates could be considered.

Given the growing number of patients on antithrombotic therapy we are increasingly confronted with the management of this therapy before, during and after vitreoretinal surgery. In the absence of a consensus, the decision to withdraw antithrombotic therapy is based on the cardiovascular thromboembolism risk versus the theoretical risk of bleeding if the antithrombotic treatment is continued. As suggested by the literature, antiplatelet therapy (acetylsalicylic acid or clopidogrel) may be safely continued for vitreoretinal surgery, including retinal detachment repair. However, the risk/benefit ratio for patients being treated with two antiplatelet therapies is unknown. It appears that an International Normalized Ratio (INR) less than 3 for patients treated with anticoagulant therapy does not increase the perioperative risk of ocular bleeding. This risk has not been evaluated in patients treated by new antithrombotic therapies (prasugrel, ticagrelor as antiplatelet medication, or dabigatran, rivaroxaban, apixaban as anticoagulant therapy), and there is a need to study it further.

BACKGROUND: Stroke volume variation (SVV) during mechanical ventilation predicts preload responsiveness. We hypothesized that the prone position would alter the performance of this dynamic indicator. METHODS: Two parallel groups of ventilated neurosurgical patients with low tidal volume (6-8 ml.kg-1) were studied before surgical incision. SVV was measured at T0, T15 and T30 min during a fluid volume expansion (250 mL hetastarch 6% over 30 min) with patients in either the supine (N.=29; Supine group) or prone position (N.=23; Prone group). Fluid responsiveness was defined as an increase in the stroke volume index (SVI) of ≥20% at T30. Receiver-operating characteristics (ROC) curves were generated for SVV. RESULTS: Prone positioning significantly increased SVV. Volume expansion in the Prone group increased SVI but led to a decline in SVV from 16% (12-22; median, 25-75th percentile) at T0 to 9% (8-13%) at T30. These effects on SVI and SVV were more pronounced compared to those obtained in the Supine group (P ≤0.05). Fluid responsiveness was predicted by SVV >12% at T0 (sensitivity 88%, specificity 62%) in the Supine group. In the Prone group, the area under the ROC curve of SVV (0.53; 95% confidence interval 0.27-0.79) did not allow the determination of a threshold SVV value. CONCLUSION: In ventilated patients with low tidal volume, a prone position may have a direct effect on the heart that alters the performance of SVV in predicting fluid responsiveness. External factor such as prone position renders difficult the interpretation of SVV as a dynamic indicator of cardiac preload.

Apixaban is a direct inhibitor of coagulation factor Xa. Superior efficacy over aspirin and antivitamin K has been shown in the prevention of stroke and systemic embolism during non-valvular atrial fibrillation with a more favorable safety profile, even though the risk of hemorrhage cannot be ignored, considering its mechanism of action. The recommended dose is 5mg twice daily which can be reduced to 2.5mg depending on the individual risk. Apixaban is also indicated for the treatment of venous thromboembolism but reimbursement has not yet been accepted in France for this indication. As with all direct oral anticoagulants, no routine biological monitoring is required, nevertheless their use may have an impact on all coagulation tests, eventually hampering interpretation. In particular clinical circumstances where a measure of anticoagulant efficacy is deemed necessary, specific assay of anti-Xa activity is appropriate, the result being expressed as concentration of the anticoagulant used. It is therefore necessary to state the name of the medicine for which the assay is requested. With these new anticoagulants, management of hemorrhagic events can be more difficult due to the lack of a specific antidote. Pro-hemostatic substances have exhibited efficacy in animal models but results are still insufficiently documented in clinical practice. Local or locoregional hemostasis measurements, when possible, are an essential factor in the treatment of hemorrhagic events.

New direct oral anticoagulants (NOAC), inhibitors of factor IIa or Xa, are expected to be widely used for the treatment of venous thromboembolic disease, or in case of atrial fibrillation. Such anticoagulant treatments are known to be associated with haemorrhagic complications. Moreover, it is likely that such patients on long-term treatment with NOAC will be exposed to emergency surgery or invasive procedures. Due to the present lack of experience in such conditions, we cannot make recommendations, but only propose management for optimal safety as regards the risk of bleeding in such emergency conditions. In this article, only dabigatran and rivaroxaban were discussed. For emergency surgery at risk of bleeding, we propose to dose the plasmatic concentration of drug. Levels inferior or equal to 30ng/mL for both dabigatran and rivaroxaban, should enable the realization of a high bleeding risk surgery. For higher concentration, it was proposed to postpone surgery by monitoring the evolution of the drug concentration. Action is then defined by the kind of NOAC and its concentration. If the dosage of the drug is not immediately available, proposals only based on the usual tests, PT and aPTT, also are presented. However, these tests do not really assess drug concentration or bleeding risk. In case of severe haemorrhage in a critical organ, it is proposed to reduce the effect of anticoagulant therapy using a nonspecific procoagulant drug (activated prothrombin concentrate, FEIBA, 30-50U/kg, or non-activated 4-factors prothrombin concentrates 50U/kg). For any other type of severe haemorrhage, the administration of such a procoagulant drug, potentially thrombogenic in these patients, will be discussed regarding concentration of NACO and possibilities for mechanical haemostasis.

BACKGROUND: Assess efficacy, satisfaction and usefulness of an educational maze based on posters and audioguide for major trauma care teaching to medical students. The educational maze consists of posters with audio comments recorded in an audioguide. This tool was part of a larger educational program including medical simulation. STUDY DESIGN: Prospective, interventional, observational, monocentric study. STUDENT: Medical student of Grenoble University Hospital, in the four last years of medical school, following a training course in anesthesia, emergency medical services and intensive care units. METHOD: Forty essentials key messages for major trauma management were included in 10 posters and audioguides. A first assessment with short opened answers was handed to the students at the end of the educational maze to assess their memorization. A second assessment with simple choice answers regarding satisfaction and usefulness of this new educational tool was realized at the end of the entire program. RESULT: One hundred and eighty-four medical students attending the major trauma program were included in this study. On the first test, 75% of essential knowledge on major trauma management was memorized by more than 50% of the medical students. On the second test, 94% of medical students had a high satisfaction level of this educational maze. CONCLUSION: An educational maze based on posters and audioguides seems to be an efficient, useful tool for teaching essential knowledge on major trauma management to medical students.

The majority of chest penetrating trauma patients are successfully managed with tube thoracostomy and general supportive measures. Pulmonary resection for hemorrhagic shock is rarely required after trauma to control bleeding. Both pulmonary injury and massive blood transfusion can lead to acute respiratory distress syndrome (ARDS). The mortality rate in these patients reaches up to 40% despite advanced ventilatory treatment. The use of extracorporeal membrane oxygenation (ECMO) can be started as rescue therapy. We report a case of 24-year-old man with major hemorrhagic shock with cardiac arrest and ARDS after traumatic penetrating lung injury that was successfully treated with pulmonary resection and ECMO.
