Analyse de coût comparant les fibroscopes à usage unique (Ambu aScope™ et les fibroscopes réutilisables pour l’intubation difficile

Objective

Recommendations on difficult tracheal intubation constrain each surgical block to have a fiberscope available. Reusable fiberscope presents the problem of availability, the risk of non-conventional infections transmission and the cost. Single-use fiberscopes are presently available (Ambu^® aScope™). This medico-economic study aims to assess the cost of using a reusable fiberscope as compared to the single use fiberscope.

Study design

Cost minimization analysis.

Material

Reusable fiberscope Pentax^® FB 15P (Pentax France, Argenteuil) and single-use fiberscope Ambu^® aScope™ (Ambu A/S, Ballerup, Denmark).

Method

Minimization-cost analysis conducted between 2006 and 2012. The amortization cost per utilization for two reusable fiberscopes took into account the acquisition and maintenance costs, as well as the costs related to disinfection. The cost of the single use fiberscope was calculated according to its acquisition cost.

Results

The total cost of the reusable material was 55,874 € over 6 years, corresponding to a unitary cost of 206 € per fiberscopy. During this period, 780 sterilizations were carried out for a total cost of 32,611 €. Acquisition and maintenance costs were respectively 18,382 € and 4880 €. The cost of the single use fiberscope is of 200 € per fiberscopy.

Conclusion

This medico-economic evaluation shows that the utilization cost of single use and reusable fiberscopes are very close. This should be analyzed at the light of some benefits of using single use devices for the difficult tracheal intubation.     

Évaluation d’un labyrinthe pédagogique pour l’enseignement de la traumatologie grave

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.     

Enquête nationale sur la prise en charge de l’intubation difficile en médecine d’urgence préhospitalière

Objectives

Difficult intubation rate is higher in the prehospital setting than in the operating room.Goal of this survey was to assess compliance of the French prehospital mobile emergency unit (Smur) to the recent French guidelines for the difficult airway management.

Study design

National phone survey.

Methods

A phone questionnaire was proposed to one senior emergency physician of all 380 French Smur. Seven questions were asked about intubation devices used, availability of a written difficult intubation algorithm and intubation training of the Smur's physicians.

Results

Guidelines of the recent French consensus conference on difficult intubation are only partly followed by the Smur. Only 60% of the Smur perform systematic rapid intubation sequence, plastic laryngoscope blades are used by more than 50% of the Smur and less than 50% of the Smur have a written difficult intubation management algorithm available. The Gum elastic Bougie is available in 58% of the Smur and the intubating laryngeal mask airway in 71%, whereas initial formation for difficult intubation devices used is provided to the emergency physicians in only 58% of the Smur.

Conclusion

This survey shows that the French guidelines for the difficult airway management are only partially followed by the French Smur. An effort should be made for a larger diffusion of these guidelines towards the emergency physicians working in the Smur.     

Gestion des voies aériennes supérieures en fin d’accouchement : enquête de pratique

Objective

To describe the airway management during general anaesthesia performed at the end of labour.

Study design

Observational retrospective study in a French university obstetrical unit.

Patients and methods

All parturients who underwent general anaesthesia for manual removal of the placenta or instrumental delivery were included. Demographic data, anaesthesia management, indication and duration of anaesthesia were recorded. Incidents as vomiting, a drop in oxygen saturation of five points or more, aspiration and difficult endotracheal intubation were investigated.

Results

Among 111 parturients with inclusion criteria, the rate of tracheal intubation was 5%. The duration of anaesthesia ranged from five to 60 minutes (mean duration: 16 min). No incident was recorded within the methodological limits of this retrospective study.

Conclusion

There is a major discrepancy between guidelines and clinical practice in our unit concerning systematic tracheal intubation during general anaesthesia performed at the end of labour. A national survey is in process to confirm these results.     

Deux utilisations consécutives de l’Airtraq néonatal chez un nourrisson d’un mois présentant une intubation difficile prévue

We used successfully Airtraq-combined to a gum-elastic boogie to intubate twice a dysmorphic infant with mucolipidosis, in whom direct laryngoscopy failed. If this result is confirmed by prospective studies, Airtraq could be a first-line device to intubate infants with difficult intubation.     

Embolie amniotique : à propos de l’issue favorable d’un cas avec arrêt cardiaque inaugural et CIVD précoce compliquée d’un hémopéritoine d’origine iatrogène et d’un saignement sur un adénome hépatique

Amniotic fluid embolism is a relatively rare clinical entity and with difficult medical recognition. However, it is the second leading cause of maternal mortality. We report here the case of a 32-year-old patient who underwent elective caesarean section complicated by an amniotic fluid embolism with cardiac arrest. The presence of a major disseminated intravascular coagulation favored the occurrence of a retroperitoneal hematoma of iatrogenic origin on attempt of femoral venous catheterization and that of hemoperitoneum on bleeding of an hepatic adenoma. The diagnostic of amniotic fluid embolism was confirmed by the presence of amniotic cells in the bronchoalveolar lavage. The patient survived without sequelae.     

Effets de l’hydroxyzine sur l’acceptation du masque à l’induction de l’enfant

Objective

To evaluate the effectiveness of hydroxyzine as a premedication agent for the acceptance of facial mask during induction of general anaesthesia in children.

Study design

Prospective randomized single-blind study including ASA 1 and 2 children, aged between 1 and 9 years and undergoing outpatient surgery.

Patients and methods

Patients were randomly allocated to receive orally either 1 mg/kg hydroxyzine (G1) or water 0.1 ml/kg (G2) one hour before induction of standardized inhalational anaesthesia. Tolerance of facial mask was assessed with a 3-points scale (good, moderate or poor). Chi-square and Student's t-test were used in statistical analysis; p values less than 0.05 were considered statistically significant.

Results

One hundred patients were included (G1 = 49, G2 = 51). Demographic data were similar in both groups. Acceptance of facial mask was significantly better in G1 than in G2 (p = 0,002).

Conclusion

Hydroxyzine provided better acceptance of facial mask than placebo during induction of general anaesthesia in children.     

Épiglottite aiguë obstructive en réanimation : stratégie pour une intubation à haut risque

Acute epiglottitis is an infection of supraglottic structures, with a high risk of life-threatening respiratory obstruction. We report a case of a 52-year-old patient who presented with a prehospital hypoxic respiratory arrest caused by obstructive oedema with a successful resuscitation. Laryngoscopy after a sudden unplanned extubation permits diagnosis of acute obstructive epiglottitis. The growing threat of laryngeal dyspnea prompts emergency tracheal airway protection, by means of the combined preparation of transtracheal oxygenation access and the use of fiber-optic laryngoscopy. This case report emphasises the airway management strategy successfully used in this patient.
