French survey of the first three-years of liver transplantation activity from uncontrolled donors deceased after cardiac death.

OBJECTIVE: To assess the first three years of French activity related to liver transplantation from uncontrolled donation after cardiac death (uDCD). STUDY DESIGN: Prospective and observational study in the three active centres authorized by the French Biomedicine Agency. PATIENTS AND METHODS: All patients deceased between 2010 and 2012 after an uncontrolled cardiac arrest admitted to one of three centres (Pitié-Salpêtrière, Saint-Louis or Bicêtre hospitals, AP-HP, Paris, France) and potentially eligible for liver recovery were included. Abdominal normothermic oxygenated recirculation (ANOR) was used for graft preservation. RESULTS: One hundred twenty-six potential uDCD donors were identified as eligible for liver recovery after hospital admission. The main causes of organ recovery failure were technical failure related to ANOR (29 patients, 23%), refusal of consent (39 patients, 31% of potential uDCD donors and 40% of asked relatives) and abnormal hepatic transaminases up to 200 UI.L(-1) during ANOR (24 patients, 19%). Finally, 11 livers were transplanted. Process efficiency was 9% [95% CI: 4-15%]. One-year recipient survival was 82%, [95% CI: 48-98%] and one-year graft survival was 64% [95% CI: 31-89%]. CONCLUSION: Liver transplantation from uDCD donors is achievable in France, despite low process efficiency.

[Perioperative conflicts between anaesthesiologists and surgeons: ethics and professionalism]. / Conflits en période périopératoire: un enjeu collectif, éthique et professionnel.

In the perioperative period, several potential conflicts between anaesthetists/intensive care specialists and surgeons may exist. They are detrimental to the quality of patient care and to the well-being of the teams. They are a source of medical errors and contribute to burn-out. Patients can become the victims of such conflicts, which deserve ethical reflection. Their resolution through analysis and shared solutions is necessary. This article seeks to analyse these conflicts, taking into account their specificities and constraints. In order to understand this context, it is important to consider the specificities of each group involved and the records of such situations. Several factors can prevent these conflicts, first and foremost the patients themselves and the quality of the care that is provided. Medical deontology aims mainly at preventing and resolving these conflicts. Generally speaking, the quality approach which is increasingly applied in health care institutions (involving declarations of adverse events, morbidity/mortality reviews, benchmarking, analysis and improvement of practices, etc.) also contributes to the prevention and resolution of disagreements. The teaching of communication techniques that begins with the initial training, the evaluation of team behaviours (through simulation training for example), the respect of others' constraints, particularly when it comes to learning, as well as transparency regarding conflicts of interests, are all additional elements of conflict prevention. Lastly, conflicts may at times be caused by deviant behaviours, which must be met with a clear and uncompromising collective and institutional approach. This article concludes by offering a standardised approach for conflict resolution.

Critical appraisal of organ procurement under Maastricht 3 condition.

The ethics committee of the French Society of Anesthesia and Intensive Care (Sfar) has been requested by the French Biomedical Agency to consider the issue of organ donation in patients after the decision to withdraw life-supportive therapies has been taken. This type of organ donation is performed in the USA, Canada, the United Kingdom, the Netherlands and Belgium. The three former countries have published recommendations formalizing procedures and operations. The French Society of Anesthesia and Intensive Care (Société française d'anesthésie et de reanimation [Sfar]) ethics committee has considered this issue and envisioned the different aspects of the whole process. Consequently, it sounded a note of caution regarding the applicability of this type of organ procurement in unselected patients following a decision to withdraw life-supportive therapies. According to French regulations concerning organ procurement in brain-dead patients, the committee stresses the need to restrict this specific way of procurement to severely brain-injured patients, once confirmatory investigations predicting a catastrophic prognosis have been performed. This suggests that the nature of the confirmatory investigation required should be formalized by the French Biomedical Agency on behalf of the French parliamentarians, which should help preserve population trust regarding organ procurement and provide a framework for medical decision. This text has been endorsed by the Sfar.

Earplugs and eye masks vs routine care prevent sleep impairment in post-anaesthesia care unit: a randomized study.

BACKGROUND: Post-anaesthesia care units (PACUs) with 24/7 activity and consequently artificial light and noise may disturb the sleep of patients who require prolonged medical supervision. After one postoperative night, we compared sleep quality in patients with and without noise (earplug) and light (eye mask) protection. METHODS: After ethical board approval, 46 patients without any neurological or respiratory failure undergoing major non-cardiac surgery were prospectively included. They were randomized to sleep with or without protective devices during the first postoperative night in the PACU. Sleep quality was simultaneously measured by sleep-quality scales (Spiegel score and Medical Outcomes Study Sleep), nurses' assessment, and through a wrist actigraph (Actiwatch). Secondary outcomes such as pain control and nocturnal activity were recorded. Comparisons between groups were made by Student's t-test or non-parametric test for repeated measures as appropriate (SPSS 10.0). A P-value <0.05 was considered significant. RESULTS: Data from 41 patients were analysed. Protective devices during the first postoperative night prevented a decrease in sleep quality compared with standard care, as evaluated by the Spiegel scale: 20 (4) vs 15 (5), P=0.006. These devices significantly decreased the need for a nap [50% 95% confidence interval (CI) (20-80) vs 95% 95% CI (85-100), P<0.001], but had no effect on sleep length evaluated by Actiwatch. The total consumption of morphine was significantly reduced in the first 24 h [respectively, 15(12) mg and 27(17) mg, P=0.02]. CONCLUSIONS: Earplugs and eye masks applied in the PACU during the first postoperative night significantly preserve sleep quality. Such non-invasive and cheap devices may be generalized in the PACU or in intensive care units.

[Euthanasia, assisted suicide and palliative care: a review by the Ethics Committee of the French Society of Anaesthesia and Intensive Care]. / Fin de vie, euthanasie et suicide assisté : une mise au point de la Société française d'anesthésie et de réanimation (Sfar).

CONTEXT: Management of the end of life is a major social issue which was addressed in France by law, on April 22nd 2005. Nevertheless, a debate has emerged within French society about the legalization of euthanasia and/or assisted suicide (E/AS). This issue raises questions for doctors and most especially for anesthetists and intensive care physicians. OBJECTIVE: To highlight, dispassionately and without dogmatism, key points taken from the published literature and the experience of countries which have legislated for E/AS. RESULTS: The current French law addresses most of the end of life issues an intensive care physician might encounter. It is credited for imposing palliative care when therapies have become senseless and are withdrawn. However, this requirement for palliative care is generally applied too late in the course of a fatal illness. There is a great need for more education and stronger incentives for early action in this area. On the rare occasions when E/AS is requested, either by the patient or their loved-ones, it often results from a failure to consider that treatments have become senseless and conflict with patient's best interest. The implementation of E/AS cannot be reduced to a simple affirmation of the Principle of autonomy. Such procedures present genuine difficulties and the risk of drift. CONCLUSION: We deliver a message of prudence and caution. Should we address painful end of life and moral suffering issues, by suppressing the subject, i.e. ending the patient's life, when comprehensive palliative care has not first been fully granted to all patients in need of it ?

Organ procurement from donors deceased from cardiac death: a single-center efficiency assessment.

Organ donation after cardiac death has been used for kidney and liver procurement in France since 2006. Until recently, most teams relied on in situ cold perfusion to prepare the donor before organ retrieval. Our team has used since 2007 normothermic abdominal recirculation. While this technique is presumed to be more difficult to implement, it also ensures a lower rate of primary nonfunction when compared to in situ cold perfusion. We present the efficiency results of our organ donation after cardiac death program. After 3 years, we have been able to establish a program in which we use normothermic abdominal recirculation in 97% of donors after cardiac death. The yearly efficiency of this program is comparable to the national efficiency of organ procurement from conventional deceased donors in France.

An evaluation of capnography monitoring during the apnoea test in brain-dead patients.

BACKGROUND AND OBJECTIVE: Diagnosis of brain death usually requires the absence of spontaneous respiratory movements during the apnoea test and an arterial carbon dioxide partial pressure above 60 mmHg. On the other hand, although capnography (end-tidal CO(2)) is currently monitored in intensive care unit patients, it has not been evaluated during the apnoea test in brain-dead patients. Therefore, the aim of this prospective study was first to investigate the usefulness of capnography monitoring, and secondly to evaluate the variation of the carbon dioxide partial pressure-end-tidal CO(2) gradient during the apnoea test in clinically brain-dead patients. METHODS: After local Ethics Committee approval, 60 clinically brain-dead patients were investigated. End-tidal CO(2) was continuously recorded before, during and after the apnoea test. Arterial blood gases were sampled immediately before and after the apnoea test for calculation of the carbon dioxide partial pressure-end-tidal CO(2) gradient. RESULTS: The apnoea test was clinically positive in 58 patients, whereas end-tidal CO(2) was equal to 0 during the apnoea. During the 20-min apnoea test, carbon dioxide partial pressure increased from 40 +/- 7 to 97 +/- 19 mmHg (P < 0.001) with a rate of 2.8 +/- 0.9 mmHg min(-1), end-tidal CO(2) increased from 31 +/- 6 to 68 +/- 17 mmHg (P < 0.001) and carbon dioxide partial pressure-end-tidal CO(2) gradient increased from 9 +/- 4 to 29 +/- 10 mmHg (P < 0.001). In two patients, the apnoea test was clinically negative because of the occurrence of spontaneous respiratory movements, whereas capnography showed contemporaneously significant increases in end-tidal CO(2). CONCLUSIONS: End-tidal CO(2) should be systematically monitored and recorded, at least for medico-legal considerations, during the apnoea test in brain-dead patients. The high variability in the carbon dioxide partial pressure-end-tidal CO(2) gradient increase precludes any extrapolation of the carbon dioxide partial pressure from the end-tidal CO(2) at the end of the apnoea test.

Early extubation after mitral valve surgery: a target-controlled infusion of propofol and low-dose sufentanil.

OBJECTIVE: In the current study, the use of a target-controlled infusion of low-dose propofol was combined with a continuous infusion of sufentanil for patients undergoing mitral valve surgery. The purpose of the study was to evaluate the hemodynamic stability, the time to awakening and spontaneous ventilation, and the feasibility in an early extubation setting of a total intravenous anesthetic technique. DESIGN: Prospective study. SETTING: University hospital. PARTICIPANTS: Fifteen patients scheduled for elective mitral valve surgery. INTERVENTIONS: Induction of anesthesia consisted of sufentanil (1 microgram/kg), propofol (1 microgram/mL) target plasma concentration achieved over 3 minutes, and atracurium (0.5 mg/kg). The propofol target-controlled infusion was maintained at 1 microgram/mL throughout surgery and stopped at skin closure. A continuous infusion of sufentanil at 1.8 micrograms/kg/hr was started after induction and reduced to 0.9 microgram/kg/hr at the start of cardiopulmonary bypass and stopped at the end of bypass. Atracurium was infused at a rate of 0.5 mg/kg/hr up to sternal closure. No inhalation agents were used. MEASUREMENTS AND MAIN RESULTS: Hemodynamic data were within normal limits. Six patients (40%) responded to verbal commands within 15 minutes postoperatively, 10 (67%) within the first hour, and all patients recovered within 2 hours. Four patients (27%) resumed spontaneous ventilation within the first 15 postoperative minutes. The time to successful spontaneous ventilation was 169 +/- 42 minutes. Spontaneous ventilation was associated with a 21% increase in cardiac index. Total sufentanil dose was 328 +/- 28 micrograms (4.6 +/- 0.2 microgram/kg), whereas total propofol dose was 862 +/- 44 mg (13.1 +/- 1.2 mg/kg). No patient required reintubation. CONCLUSION: The simplicity of the method with only one change in infusion rate is a major advantage. The technique permits predictable recovery and return to spontaneous ventilation in all patients. Its use in patients entering early extubation protocols is appealing for its reproducibility, simplicity, and safety.
