Hemoperitoneum in peripartum: A case-series.

Hemorrhages are the first cause of perinatal deaths in French women. Thirteen percent of these deaths are not linked to obstetrical problems but rather to hemoperitoneum. These incidents are under-diagnosed and as a result, treatment is delayed and fetal and maternal mortality increases. We report three cases of patients, all White female in their last trimester of a non-problematic pregnancy presenting with hemoperitoneum and resulting in different outcomes. The analysis of published materials and of our cases leads us to infer that a diagnosis of hemoperitoneum must be considered in pregnant women when abdominal pain, symptoms of shock and a decrease in hemoglobin are associated. An immediate response and intensive care followed by hemostatic surgery give these patients the best chance to survive.

Cost analysis of single-use (Ambu® aScope™) and reusable bronchoscopes in the ICU.

BACKGROUND: Flexible optical bronchoscopes are essential for management of airways in ICU, but the conventional reusable flexible scopes have three major drawbacks: high cost of repairs, need for decontamination, and possible transmission of infectious agents. The main objective of this study was to measure the cost of bronchoalveolar lavage (BAL) and percutaneous tracheostomy (PT) using reusable bronchoscopes and single-use bronchoscopes in an ICU of an university hospital. The secondary objective was to compare the satisfaction of healthcare professionals with reusable and single-use bronchoscopes. METHODS: The study was performed between August 2009 and July 2014 in a 16-bed ICU. All BAL and PT procedures were performed by experienced healthcare professionals. Cost analysis was performed considering ICU and hospital organization. Healthcare professional satisfaction with single-use and reusable scopes was determined based on eight factors. Sensitivity analysis was performed by applying discount rates (0, 3, and 5%) and by simulation of six situations based on different assumptions. RESULTS: At a discount rate of 3%, the costs per BAL for the two reusable scopes were 188.86€ (scope 1) and 185.94€ (scope 2), and the costs per PT for the reusable scope 1 and scope 2 and single-use scopes were 1613.84€, 410.24€, and 204.49€, respectively. The cost per procedure for the reusable scopes depended on the number of procedures performed, maintenance costs, and decontamination costs. Healthcare professionals were more satisfied with the third-generation single-use Ambu® aScope™. CONCLUSIONS: The cost per procedure for the single-use scope was not superior to that for reusable scopes. The choice of single-use or reusable bronchoscopes in an ICU should consider the frequency of procedures and the number of bronchoscopes needed.

[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.

[Use of the intraosseous access in adult patients in France in 2012]. / Utilisation de la voie intraosseuse chez l'adulte en France en 2012.

OBJECTIVES: To evaluate theoretical and practical knowledges of intraosseous (IO) access in adults patients in France in 2012. STUDY DESIGN: National observational descriptive transversal study as survey of opinion and practices. MATERIALS AND METHODS: An email, with an URL to online computerized quiz, was sent to residents and medical doctors who were working, in France, in anesthesiologist units, intensive care units or emergency units. Several questions were asked about theoretical and practical knowledges concerning IO access. RESULTS: After 1359 responses, 396 (29%) practitioners have used an IO kit mainly in case of cardiopulmonary arrest in adults (68%). The insurance of operators in this technique and the rate of physicians who has even put an IO catheter increased with the years of experience of physicians. The reasons given for not using an IO access were no trouble placing a peripheral vein (77%) and unfamiliarity with the equipment and technology (32%). Most of practitioners (753 [55%]) have been trained and 90% (n=265) of untrained doctors believe that training was necessary. The powered system was the most used (71%). CONCLUSION: Only 29% of practitioners have ever used an IO kit. With the new IO kits, a theoretical and practical training is needed to ensure IO kit used.

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.

A pharmacokinetic study of 48-hour sevoflurane inhalation using a disposable delivery system (AnaConDa®) in ICU patients.

BACKGROUND: Little is known regarding sevoflurane kinetics and toxicity during long-term sedation of intensive care unit (ICU) patients using the AnaConDa® system. The objective of the present study was to establish a pharmacokinetic description of 48-h sevoflurane administration, and to estimate plasma concentrations of metabolites. METHODS: Forty-eight hour sedation with sevoflurane vaporized via an AnaConDa® device, with an end-tidal concentration objective of 1.5% (v/v), was initiated in 12 non-obese patients who did not have hepatic or renal failure but who required sedation for more than 48 h in our ICU. Plasma sevoflurane, hexafluoroisopropanol, and fluoride concentrations were determined over this time period and pharmacokinetic analysis was performed. RESULTS: The mean plasma concentration of sevoflurane was 76 mg/L at 24 h and 70 mg/L at 48 h. Wash-out of plasma sevoflurane correlated with a rapid decrease in the mean end-tidal sevoflurane level. The mean free plasma fraction of hexafluoroisopropanol never exceeded 8 mg/mL. The mean fluoride concentration was 0.8 µmol/L on day 0, 51.7 µmol/L on day 1, and 68.1 µmol/L on day 2 (P<0.0001). The distribution volume was 53 L, the elimination constant 2.9 h-1, the transfer constant from compartment 1 to compartment 2 (K1-2) 1.2 h-1, the K2-1 0.26 h-1, the half-life of elimination 3.78 h, and the total clearance 156 L/h. CONCLUSION: Following 48 hours of sedation using sevoflurane inhalation administered using an AnaConDa® delivery device, sevoflurane washout was rapid. Plasma fluoride levels accumulated over the study period without apparent nephrotoxicity.

Epidural injection of hydroxyethyl starch in the management of postdural puncture headache.

Epidural blood patch is the standard treatment for postdural puncture headache when symptomatic therapy is ineffective. We report the cases of two patients who received an epidural injection of hydroxyethyl starch when an epidural blood patch was contraindicated; one due to Streptococcus agalactiae bacteraemia and one due to acute leukaemia. Relief of headache was achieved in both patients with no adverse effects. The use of an epidural hydroxyethyl starch injection may be a suitable alternative for treatment of postdural puncture headache if epidural blood patch is contraindicated.

[Antimicrobial prophylaxis for caesarean delivery: changes in practice and administration before incision, feasibility study to paediatricians in Auvergne]. / Antibioprophylaxie pour césarienne: modification des pratiques et administration avant incision, enquête de faisabilité auprès des pédiatres du réseau de santé périnatale d'Auvergne (RSPA).

OBJECTIVE: To describe the knowledge of paediatricians regarding the practice of antimicrobial prophylaxis for caesarean section in reference to the Consensus Conference of the French Society of Anesthesia and Intensive Care (SFAR) and assess the feasibility of a change in attitude (injection of the antibiotic prior to incision) among paediatricians Perinatal Health Network of Auvergne (RSPA) working in maternity. STUDY DESIGN: Cross sectional study by survey. METHODS: First questionnaire was sent to 46 RSPA paediatricians working in maternity. Almost one-third of paediatricians who returned the questionnaire said they were not concerned. A second questionnaire was developed with two paediatricians of the CHU and sent to the same 46 paediatricians. The statistical part involved percentages. RESULTS: Response rates were respectively 61% and 67%. For the first questionnaire, only 25% of the paediatricians knew the antibiotic and the time for injection. For the second questionnaire, 87% were in favour of an administration before incision and 42% thought it will not affect the care of the newborn. For 35% of respondents, it could lead to a change in the duration of antibiotic therapy in cases of perinatal infection and for 13% only a delay in the implementation of antibiotic therapy in children. CONCLUSION: The RSPA paediatricians did not know the practices of antibiotic prophylaxis for caesarean section. However, they did not appear opposed to an administration before cord clamping as it would not delay the implementation of any antibiotics in the newborn.

Management of HSV-1 encephalitis due to reactivation of HSV-1 during late pregnancy.

A previously healthy 31-year-old G4P2 woman at 33 weeks of gestation was admitted as an emergency with a pyrexia of 39°C, vomiting, headache and neck stiffness associated with photophobia, phonophobia and visual and auditory symptoms. There were no heraldic signs of eclampsia. Polymerase chain reaction and testing for herpes simplex virus in the cerebrospinal fluid diagnosed herpes simplex-1 meningoencephalitis. Following acyclovir, the clinical course improved. Spontaneous vaginal delivery occurred at 39 weeks of gestation with epidural analgesia using ropivacaine. Mother and child were neurologically normal and healthy 15 months later. Early administration of acyclovir is essential to reduce the risk of neurological complications. After treatment and a negative polymerase chain reaction for herpes simplex virus in the cerebrospinal fluid, epidural analgesia with local anesthetic and sufentanil is possible.

[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 ?

Influence of opioid choice on mechanical ventilation duration and ICU length of stay.

BACKGROUND: The aim of this study was to assess the impact on mechanical ventilation and ICU outcomes of substituting remifentanil for sufentanil, in an analgesia-based sedation protocol. A database of data prospectively collected was retrospectively analyzed. The study was carried out in a 16-bed tertiary-care ICU. METHODS: The study included 1544 mechanically ventilated patients admitted from January 2001 to December 2006. Patients were compared between two consecutive phases. Analgesia-based sedation guidelines were the same, except for the opiate used. The patient-to-nurse ratio (2.5) and ventilator weaning practices remained unchanged. 794 patients were included during the sufentanil phase, and 750 during the remifentanil phase. Remifentanil was associated with significantly less time spent on mechanical ventilation (10 days[3-21] vs. 14 days[3-27], P<0.01) and in the ICU (16 days[3-22] vs. 19 days[4-26], P<0.01). The difference was significant for patients ventilated no longer than four days (P=0.0035) but not for patients ventilated more than four days (P=0.058). Sedation target on the Ramsay scale was reached more often with remifentanil. The use and amount of hypnotic agents in addition to the opiate were significantly lower with remifentanil. The cost of analgesia-based sedation was similar in the sufentanil and the remifentanil group. CONCLUSION: Our study suggests that using a short-acting opiate with short context-sensitive half-life in an analgesia-based sedation protocol may significantly decrease the duration of mechanical ventilation and the ICU length of stay even though not significantly in long term sedation, while improving the achievement of sedation goals despite a lower requirement for adjunctive hypnotic agents, with no additional costs.

Addition of clonidine to a continuous patient-controlled epidural infusion of low-concentration levobupivacaine plus sufentanil in primiparous women during labour.

We studied the potentiation of analgesia for labour by the addition of clonidine to epidural low-concentration levobupivacaine with sufentanil in a randomised, double-blinded study. We enrolled primiparous women who were in spontaneous labour. The study solutions, made of 100 ml levobupivacaine 0.0625% plus sufentanil 0.45 µg.ml(-1) and either 150 µg clonidine or no clonidine, were used for induction of analgesia, and for its maintenance with self-administered boluses and a continuous background infusion. The need for additional epidural boluses during labour was lower and analgesia and maternal satisfaction were better in the clonidine (n = 57) than in the control group (n = 58). Blood pressure was lower and the rate of instrumental delivery higher in the clonidine group. Clonidine (1.36 µg.ml(-1)) added to the epidural solution of low-concentration levobupivacaine improves the quality of analgesia. The relevance of the haemodynamic effects should be explored in larger validation studies.

[Post-partum haemorrhage in delivery room: anaesthetists' practioner in Auvergne]. / Hémorragie du post-partum en salle de naissance : pratique déclarée des anesthésistes en région Auvergne.

OBJECTIVE: To assess the management of post-partum haemorrhage (PPH) in delivery rooms by the anaesthetists of the Auvergne region. STUDY DESIGN: Cross sectional study. METHODS: An anonymous postal survey was sent to all the anaesthetists working in a public or private hospital with a maternity unit. RESULTS: The response rate was about 70 %. Eight percent of the respondents never practiced in obstetrics; others all declared to have managed PPH at least once. Only 66 % declared to know the right definition of PPH, 98 % declared to have guidelines in the delivery room, 87 % to use graduate blood receipt pockets, 85 % to work under midwives-directed delivery at expulsion, 88 % to have a HemoCue™ system. More than 80 % declared to use first oxytocin and to switch for prostaglandins in case of failure, to put two venous catheters and a urinary catheter, to administer broad-spectrum prophylactic antibiotic and to draw a blood sample for early biology. Packed red cells, platelets and fresh frozen plasma were accessible in less than 30 minutes for 98 %. Transfusion guidelines were applied. Only 27 % could have arterial radiologic embolisation on site. The knowledge about PPH and its consensual care tended to be poorer in practitioners from the university hospital, and younger under 40 also. CONCLUSION: This survey, with a good response rate, showed a practice generally fitting to the guidelines, although with some failures depending on the practioner's age and type of hospital.

[Benefits and indications of xenon anaesthesia]. / Avantages décisifs, indications et limites de l'anesthésie au xénon.

OBJECTIVE: To analyze the current knowledge related to xenon anaesthesia. DATA SOURCES: References were obtained from computerized bibliographic research (Medline), recent review articles, the library of the service and personal files. STUDY SELECTION: All categories of articles on this topic have been selected. DATA EXTRACTION: Articles have been analyzed for biophysics, pharmacology, toxicity and environmental effects, clinical effects and using prospect. DATA SYNTHESIS: The noble gas xenon has anaesthetic properties that have been recognized 50 years ago. Xenon is receiving renewed interest because it has many characteristics of an ideal anaesthetic. In addition to its lack of effects on cardiovascular system, xenon has a low solubility enabling faster induction of and emergence from anaesthesia than with other inhalational agents. Nevertheless, at present, the cost and rarity of xenon limits widespread use in clinical practice. The development of closed rebreathing system that allowed recycling of xenon and therefore reducing its waste has led to a recent interest in this gas. CONCLUSION: Reducing its cost will help xenon to find its place among anaesthetic agents and extend its use to severe patients with specific pathologies.

Continuous patient-controlled epidural infusion of levobupivacaine plus sufentanil in labouring primiparous women: effects of concentration.

The effects of two different concentrations of epidural levobupivacaine were compared when used to provide analgesia for labour. Primiparous women in spontaneous uncomplicated labour were enrolled in a prospective, randomised and partially double-blinded study. The study solutions were either 0.568 mg x ml(-1) levobupivacaine (low concentration group) or 1.136 mg x ml(-1) levobupivacaine (high concentration group), with sufentanil 0.45 microg x ml(-1) added to both solutions. Epidural analgesia was initiated with 20 ml of the study solution, followed by a standardised algorithm of top-up bolus injections. Epidural analgesia was then continued by self-administered boluses of 5-ml plus a continuous infusion of 5 ml x h(-1). Analgesia was found to be more efficacious in the high-concentration group. The dose of levobupivacaine administered was higher and sometimes overstepping recommended limits in the high concentration group, but with no observed increase in side-effects. The choice between these two concentrations may still be made according to the patient's and the practitioner's preferences. The effects of an intermediate concentration should be studied in the future.
