 A Serious Adult Intraosseous Catheter Complication and Review of the Literature.

 
----------------------------------
Cette observation rapporte une extravasation d'amines pressives responsable d'une ischémie aiguë sévère de membre. Ceci est connu. Ce qui est intéressant c'est la proposition de recours à l'échographie pour confirmer la bonne position de l'aiguille.
----------------------------------

OBJECTIVE:

Current guidelines recommend the use of intraosseous access when IV access is not readily attainable. The pediatric literaturere ports an excellent safety profile, whereas only small prospective studies exist in the adult literature. We report a case of vasopressor extravasation and threatened limb perfusion related to intraosseous access use and our management of the complication. We further report our subsequent systematic review of intraosseous access in the adult population.

DATA SOURCES:

Ovid Medline was searched from 1946 to January 2015.

STUDY SELECTION:

Articles pertaining to intraosseous access in the adult population (age greater than or equal to 14 years) were selected. Search terms were "infusion, intraosseous" (all subfields included), and intraosseous access" as key words.

DATA EXTRACTION:

One author conducted the initial literature review. All authors assessed the methodological quality of the studies and consensus was used to ensure studies met inclusion criteria.

DATA SYNTHESIS:

The case of vasopressor extravasation was successfully treated with pharmacologic interventions, which reversed the effects of the extravasated vasopressors: intraosseous phentolamine, topical nitroglycerin ointment, and intraarterial verapamil and nitroglycerin. Our systematic review of the adult literature found 2,332 instances of intraosseous insertion. A total of 2,106 intraosseous insertion attempts were made into either the tibia or the humerus; 192 were unsuccessful, with an overall success rate of 91%. Five insertions were associated withserious complications. A total of 226 insertion attempts were made into the sternum; 54 were unsuccessful, with an overall success rate of 76%.

 ----

Color Doppler ultrasonography has been described as a method to verify placement of an intraosseous catheter. A high-frequency linear array transducer is placed near the intraosseous insertion site in either transverse or longitudinal axis. The color Doppler sample box is adjusted to include the subcutaneous compartment, the periosteum, and the intraosseous space, with the tomographic plane oriented to intersect the axis of the intraosseous needle . A 10-mL syringe filled with normal saline is attached to the intraosseous catheter and is rapidly infused with real-time ultrasonography imaging. If the intraosseous catheter is properly placed, color Doppler signal is seen in the subperiosteal (intraosseous) compartment. The presence of color Doppler signal in the extraosseous compartment indicates improper intraosseous catheter placement with extravasation.

CONCLUSIONS:

Intraosseous catheter insertion provides a means for rapid delivery of medications to the vascular compartment with a favorable safety profile. Our systematic literature review of adult intraosseous access demonstrates an excellent safety profile with serious complications occurring in 0.3% of attempts. We report an event of vasopressor extravasation that was potentially limb threatening. Therapy included local treatment and injection of intraarterial vasodilators. Intraosseous access complications should continue to be reported, so that the medical community will be better equipped to treat them as they arise.

Echo pour abord vasculaire: Intérêt modéré ?

Ultrasound guidance versus anatomical landmarks for subclavian or femoral vein catheterization

Cochrane Database Syst Rev. 2015 Jan 9;1:CD011447. doi: 10.1002/14651858.CD011447.

-------------------------------------

La mise en place d'un abord veineux central est une éventualité peu fréquente en médecine tactique. La maîtrise de l'abord vasculaire périphérique et l'apport de la perfusion intraosseuse suffisent le plus souvent à répondre aux besoins. Néanmoins ce besoin ne peut être écarté. Alors que la majorité des sociétés savantes recommandent le recours à la pose échoguidée, il semblerait qu'une analyse critique de l'intérêt d'une telle pratique ne soit pas encore complètement en faveur de telles recommandations (???). Même si de très grandes avancées technologiques ont lieu et permettent de disposer d'appareil et de sondes adhoc utilisables hors de l'hôpital, dans nos conditions d'exercice et donc in fine de notre aptitude à cette pratique sans échographe.

-------------------------------------

BACKGROUND:

Central venous catheters can help with diagnosis and treatment of the critically ill. The catheter may be placed in a large vein in the neck (internal jugular vein), upper chest (subclavian vein) or groin (femoral vein). Whilst this is beneficial overall, inserting the catheter risks arterial puncture and other complications and should be performed in as few attempts as possible.In the past, anatomical 'landmarks' on the body surface were used to find the correct place to insert these catheters, but ultrasound imaging is now available. A Doppler mode is sometimes used to supplement plain 'two-dimensional' ultrasound.

OBJECTIVES:

The primary objective of this review was to evaluate the effectiveness and safety of two-dimensional ultrasound (US)- or Dopplerultrasound (USD)-guided puncture techniques for subclavian vein, axillary vein and femoral vein puncture during central venous catheter insertion in adults and children. We assessed whether there was a difference in complication rates between traditional landmark-guided and any ultrasound-guided central vein puncture.When possible, we also assessed the following secondary objectives: whether a possible difference could be verified with use of the US technique versus the USD technique; whether there was a difference between using ultrasound throughout the puncture ('direct') and using it only to identify and mark the vein before starting the puncture procedure ('indirect'); and whether these possible differences might be evident in different groups of patients or with different levels of experience among those inserting the catheters.

SEARCH METHODS:

We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (2013, Issue 1), MEDLINE (1966 to 15 January 2013), EMBASE (1966 to 15 January 2013), the Cumulative Index to Nursing and Allied Health Literature (CINAHL) (1982 to 15 January 2013), reference lists of articles, 'grey literature' and dissertations. An additional handsearch focused on intensive care and anaesthesia journals and abstracts and proceedings of scientific meetings. We attempted to identify unpublished or ongoing studies by contacting companies and experts in the field, and we searched trial registers. We reran the search in August 2014. We will deal with any studies of interest when we update the review.

SELECTION CRITERIA:

Randomized and quasi-randomized controlled trials comparing two-dimensional ultrasound or Doppler ultrasound versusan anatomical 'landmark' technique during insertion of subclavian or femoral venous catheters in both adults and children.

DATA COLLECTION AND ANALYSIS:

Three review authors independently extracted data on methodological quality, participants, interventions and outcomes of interest using a standardized form. We performed a priori subgroup analyses.

MAIN RESULTS:

Altogether 13 studies enrolling 2341 participants (and involving 2360 procedures) fulfilled the inclusion criteria. The quality of evidence was very low (subclavian vein N = 3) or low (subclavian vein N = 4, femoral vein N = 2) for most outcomes, moderate for one outcome (femoral vein) and high at best for two outcomes (subclavian vein N = 1, femoral vein N = 1). Most of the trials had unclear risk of bias across the six domains, and heterogeneity among the studies was significant. For the subclavian vein (nine studies, 2030 participants, 2049 procedures), two-dimensional ultrasound reduced the risk of inadvertent arterial puncture (three trials, 498 participants, risk ratio (RR) 0.21, 95% confidence interval (CI) 0.06 to 0.82; P value 0.02, I² = 0%) and haematoma formation (three trials, 498 participants, RR 0.26, 95% CI 0.09 to 0.76; P value 0.01, I² = 0%). No evidence was found of a difference in total or other complications (together, US, USD), overall (together, US, USD), number of attempts until success (US) or first-time (US) success rates or time taken to insert the catheter (US). For the femoral vein, fewer data were available for analysis (four studies, 311 participants, 311 procedures). No evidence was found of a difference in inadvertent arterial puncture or other complications. However, success on the first attempt was more likely with ultrasound (three trials, 224 participants, RR 1.73, 95% CI 1.34 to 2.22; P value < 0.0001, I² = 31%), and a small increase in the overall success rate was noted (RR 1.11, 95% CI 1.00 to 1.23; P value 0.06, I² = 50%). No data on mortality or participant-reported outcomes were provided.

AUTHORS' CONCLUSIONS:

On the basis of available data, we conclude that two-dimensional ultrasound offers small gains in safety and quality when compared with an anatomical landmark technique for subclavian (arterial puncture, haematoma formation) or femoral vein (success on the first attempt) cannulation for central vein catheterization. Data on insertion by inexperienced or experienced users, or on patients at high risk for complications, are lacking. The results for Doppler ultrasound techniques versus anatomical landmark techniques are uncertain.

Intraosseux: Une place réelle à la guerre

Saving the critically injured trauma patient: a retrospective analysis of 1000 uses of intraosseous access

Lewis P et Al. Emerg Med J. 2015 Jun;32(6):463-7

OBJECTIVE:

Intraosseous access (IO) is becoming increasingly accepted in adult populations as an alternative to peripheral vascular access; however, there is still insufficient evidence in large patient groups supporting its use.

METHODS:

Retrospective review. This paper reports on the use of IO devices over a 7-year period from August 2006 to August 2013 during combat operations in Afghanistan. A database search of the Joint Theatre Trauma Registry (JTTR) was carried out looking for all the incidences of IO access use during this time. Excel (Microsoft) was used to manage the dataset and perform descriptive statistics on the patient demographics, injuries, treatments and complications that were retrieved.

RESULTS:

1014 IO devices were used in 830 adult patients with no major complications. The rate of minor complications, the majority of which were device failure, was 1.38%. 5124 separate infusions of blood products or fluids occurred via IO access, with 36% being of packed red cells. On average, each casualty received 6.95 different infusions of blood products and fluids, and 3.28 separate infusions of drugs through IO access. 32 different drugs were infused to 367 patients via IO, the most frequent being anaesthetic agents. IO access was used in the prehospital environment, during tactical helicopter evacuation and within hospitals.

CONCLUSIONS:

IO access can be used to administer a wide variety of life-saving medications quickly, easily and with low-complication rates. This highlights its valuable role as an alternative method of obtaining vascular access, vital when resuscitating the critically injured trauma patient.

Intraosseux = Embolie graisseuse

Fat Intravasation from Intraosseous Flush and Infusion Procedures

Rubal BJ et Al. 
Prehosp Emerg Care. 2015 Jul-Sep;19(3):376-90

----------------------------------

On s'en doutait mais cela est objectivé: Le recours à la perfusion intraosseuse est responsable d'embolie graisseuse. La survenue d'une telle complication est moindre quand la procédure de flush ne dépasse pas 300mmHg et que le débit est lent. Dont acte au moins pour le flush.

----------------------------------

 

STUDY HYPOTHESIS:

The primary study objective was to delineate the procedural aspects of intraosseous (IO) infusions responsible for fatintravasation by testing the hypothesis that the fat content of effluent blood increases during IO infusions.

METHODS:

IO cannulas were inserted into the proximal tibiae of 35 anesthetized swine (Sus scrofa, 50.1 ± 3.5 kg) and intravasated fat was assessed using a lipophilic fluoroprobe (Nile red) and by vascular ultrasound imaging. Effluent blood bone marrow fat was assessed at baseline, during flush, and with regimens of controlled infusion pressures (73-300 mmHg) and infusion flow rates (0.3-3.0 mL per second). Fat intravasation was also assessed with IO infusions at different tibial cannulation sites and in the distal femur. In 7 animals, the lipid uptake of alveolar macrophages and lung tissue assessed for fat embolic burden using oil red O stain 24 hours post infusion. Additionally, bone marrow shear-strain was assessed radiographically with IO infusions.

RESULTS:

Fat intravasation was observed during all IO infusion regimens, with subclinical pulmonary fat emboli persisting 24 hours post infusion. It was noted that initial flush was a significant factor in fat intravasation, low levels of intravasation occurred with infusions ≤300 mmHg, fat intravasationand bone marrow shear-strain increased with IO infusion rates, and intravasation was influenced by cannula insertion site. Ultrasound findings suggest that echogenic particles consistent with fat emboli are carried in fast and slow venous blood flow fields. Echo reflective densities were observed to rise to the nondependent endovascular margins and coalesce in accordance with Stoke's law. In addition, ultrasound findings suggested that intravasated bone marrow fat was thrombogenic.

CONCLUSION:

Results suggest that in swine the intravasation of bone marrow fat is a common consequence of IO infusion procedures and that its magnitude is influenced by the site of cannulation and infusion forces. Although the efficacy and benefits of IO infusions for emergent care are well established, emergency care providers also should be cognizant that infusion procedures affect bone marrow fat intravasation.

Accès veineux: Vision israélienne

Intravenous access in the prehospital settings: What can be learned from point-of-injury experience

Nadler R et Al. J Trauma Acute Care Surg. 2015;79: 221-226

-----------------------------------

La réalisation d'un abord vasculaire est un des gestes le plus souvent pratiqué. On rappelle qu'il s'agit là de pouvoir injecter certains médicaments (morphine, adrénaline, TXA, antibiotiques), d'initier un remplissage vasculaire raisonné voire d'administrer des dérives sanguins ou fractions coagulantes. Un document intéressant qui émane de l'armée israélienne fait le point sur cette pratique. Dans cette dernière (qui on le rappelle est assez spécifique compte tenu de la grande proximité des zones de combat et des structures hospitalières), il apparaît  qu'il ne faille pas aller au delà de deux tentatives de pose de VVP au risque de retarder la prise en charge chirurgicale des blessés. Par ailleurs les taux de succès des médecins, combat medics et paramédics (pour nous nos infirmiers) soit superposable. Enfin la médiocre performance de l'accès intra-osseux doit interpeller.

-----------------------------------

BACKGROUND:

Intravenous (IV) access has an essential role in the care provided for trauma patients, allowing for transfusion of blood products, fluids, and drugs. Decisions should be made regarding the necessity of IV access while considering cost-benefit of the procedure in terms of delayed evacuation times.

METHODS:

A retrospective review of all trauma patients in whom at least one attempt at IVaccess was performed were reviewed. Data were abstracted from the Israeli Defense Force Trauma Registry.

RESULTS:

Of 7,476 patients, 1,082 patients who had at least one documented attempt at IV access between January 1997 and April 2013 were included in this study. Overall cumulative success rate at IV access was 82%. Success rates for IVaccess were 86%, 68%, 63%, 50%, 20% for the first, second, third, fourth, and fifth attempts, respectively. The first and second attempts accounted for 96% of the successful procedures. Mortality in patients for whom IV access was successful was 13%; mortality in patients for whom IV access was not successful was 35%.

VenousAccess.jpeg

CONCLUSION:

The success rate of IV access declined with each subsequent attempt. There was minimal improvement of overall success rate seen after the second attempt. Our findings suggest that the inability to obtain peripheral venous access is associated with severe injuries. These finding support a policy of limiting the number of venous access attempts to two attempts, followed by a reevaluation of need for parenteral access. Improved training of combat medics and paramedics might marginally increase the success rates of IVaccess. Point-of-injury data, used for ongoing learning and research, form the ground for improving combat casualty care and thus help saving lives.

Intraosseux: Pourquoi pas la mandibule ?

Intraosseous Vascular Access through the Anterior Mandible – A Cadaver Model Pilot Study

Goldschalt C. et Al. PLoS One. 2014; 9(11): e112686.

-----------------------------------------------------

L'anesthésie intraosseuse est bien connue des chirurgiens dentistes. Pour autant s'agit il d'une voie potentielle d'abord vasculaire ? Peut être, sous réserve de respecter la zone de ponction et éviter le nerf dentaire inférieur.

-----------------------------------------------------

Background

Several insertion sites have been described for intraosseous puncture in cases of emergencies when a conventional vascular access cannot be established. This pilot study has been designed to evaluate the feasibility of the mandibular bone for the use of an intraosseous vascular access in a cadaver model.

Methodology/Principal Findings

17 dentistry and 16 medical students participating in a voluntary course received a short introduction into the method and subsequently used the battery powered EZ-IO system with a 15 mm cannula for a puncture of the anterior mandible in 33 cadavers. The time needed to perform each procedure was evaluated. India ink was injected into the accesses and during the anatomy course cadavers were dissected to retrace the success or failure of the puncture. Dental students needed 25.5±18.9(mean±standard deviation)s and medical students 33±20.4 s for the procedure (p=0.18). Floor of mouth extravasation occurred in both groups in 3 cases. Success rates were 82 and 75% (p=0.93). 

intraosseux

Conclusions/Significance

Despite floor of mouth extravasation of injected fluid into a mandibular intraosseous access might severely complicate this procedure, the anterior mandible may be helpful as an alternative to other intraosseous and intravenous insertion sites when these are not available in medical emergencies.

BIG: Pas si évident !

The israeli defense force experience with intraosseous access

Nadler R.et All. Mil Med. 2014 Nov;179(11):1254-7

----------------------------------------------------------------------

La réalisation d'un abord vasculaire peut faire appel à la voie intraosseuse. Trois dispositifs sont prévus par la procédure du sauvetage au combat: le trocard de mallarmé, le BIG et l'EZ_IO. Si les études expérimentales sont en faveur de cette pratique, la réalité ne semble pas suivre notamment pour le BIG. Relativement peu de dispositifs ont eu un emploi enregistré avec un taux de succès faible. Peut être un problème de stratégie d'emploi ?

----------------------------------------------------------------------

INTRODUCTION:

Obtaining vascular access is of paramount importance in trauma care. When peripheral venous access is indicated but cannot be obtained, the intraosseous route represents an alternative. The Bone Injection Gun (BIG) is the device used for intraosseous access by the Israeli Defense Force (IDF). The purpose of this study is to assess the success rate of intraosseous access using this device.

METHOD:

The IDF Trauma Registry from 1999 to 2012 was searched for patients for whom at least 1 attempt at intraosseous access was made.

RESULTS:

37 attempts at intraosseous access were identified in 30 patients. Overall success rate was 50%. No differences in success rates were identified between different care givers. Overall mortality was 87%.

CONCLUSION:

The use of BIG in the IDF was associated with a low success rate at obtaining intraosseous access. Although inability to achieve peripheral venous access can be considered an indicator for poor prognosis, the high mortality rate for patients treated with BIG can also stand for the provider's low confidence in using this tool, making its usemaking its use a last resort. This study serves as an example to ongoing learning process that includes data collection, analysis, and improvement, constantly taking place in the IDF

Perfuser + vite: Pas n'importe comment !

Novel rapid infusion device for patients in emergency situations

Kapoor DJ et Al. Scand J Trauma Resusc Emerg Med. 2011 Jun 10;19:35

Il peut être nécessaire d'accélérer le débit d'une perfusion. Pour cela il peut être fait appel à une manchette à pression, une tubulure de type 'blood pump", un système "robinet 3 voies ", plus rarement un système à compression par lame voire une pompe électrique.

Le document présenté fait appel à l'injection d'air dans le corps du soluté utilisé. La sécurité de cette manière de faire interpelle quelque peu. En effet les auteurs estiment que le filtre 15µ présent dans la tubulure a un effet barrière anti air suffisant pour éviter tout risque d'embolie gazeuse. 

Rapidnfusion.jpgCe type de pratique est associé à une prise de risque du fait du concept même de la méthode, des conditions d'hygiène non respectées et des conditions de surveillance non optimales en conditions extrême.

L'intraosseuse: Pas adaptée au dammage control resuscitation?

What is the evidence of utility for intraosseous blood transfusion in damage-control resuscitation ?

Harris M et all. J Trauma Acute Care Surg. 2013 Nov;75(5):904-6

 « The scientific and clinical evidence for the use of IO access is voluminous, as evidenced by the Scientific Bibliography provided by VidaCare,6  one of the large manufacturers of IO devices, and available in any routine literature search. However direct scientific and/or clinical data to support the use of IO access for the purpose of blood transfusion in adult humans are very limited to anecdotal reports.

the absence of good evidence supporting the use of IO access for the very critical function of blood transfusion in DCR places existing recommendations for its use in question. This lack of evidence is compounded by the clinical experience of the lead author. Multiple attempts to use IO access for blood transfusion, both in the civilian adult emergency setting and in combat casualty care, have repeatedly been unsuccessful »

«  The bone mineral density increases with age up to a peak density occurring in the early 20s. The soldier population is aged right at the peak of bone density for all races and sex.

the viscosity of pRBCs used in DCR is estimated to be greater than 10 cP.12  Since pRBCs are 10+ times more viscous than crystalloid solutions, it will require at least 10+ times the pressure to obtain the same flow rate as crystalloid in IO infusion.

Based on the Darcy’s Law, the only parameter a medical practitioner has to adjust to increase flow rate in an IO system in DCR is pressure. Increases in pressure not only strain the connections in the infusion system itself but also increase shearing forces in the fluid. Shearing forces may cause hemolysis of the transfused blood, loss of oxygen carrying capacity, and consequent development of rhabdomyolysis

we postulate that maximum flow rates attainable for transfusion of blood products used in DCR via the IO route are simply inadequate for successful resuscitation »

BIG: Du nouveau et en MIEUX

La mise en place d'un abord intra-osseux peut faire appel à une aiguille de Jamshidi, le Bone Injection Gun ou BIG et l'EZ-IO. Le BIG est un dispositif à impaction dont l'efficacité est reconnue mais dont le maniement peut être délicat. La société PersysMedical propose une novelle version du BIG qui corrige certains défauts. La clavette de sécurité est remplacée par un dispositif de sécurité beaucoup plus pratique, il n'est pas possible d'initier la percussion tant que le dispositif n'est pas plaqué à 90° contre une surface plane. Enfin ce déclenchement nécessite une poussée important puis l'attraction du corps du dispositif évitant ainsi un déclenchement intempestif du système.

TROISIEME POINT: Le BIG : Des échecs en tibial, des diifcultés pour sortir le mandrin à la main

 

In all four unsuccessful attempts with the BIG, the cannula did not penetrate the bone cortex, probably due to incorrect insertion site in three patients and excessive overlying soft tissue in one patient. All four unsuccessful attempts were tibial. In five patients the stylet was stuck within the cannula and could only be removed with a clamp. After removal of the stylet the administration of drugs and fluids through the cannula was possible without further complications and the IO insertion deemed successful.

Two unsuccessful attempts with the EZ-IO failed because of extravasation at the humeral head insertion site, probably due to incorrect insertion site and excessive overlying soft tissue.

Other technical problems like bending and breaking of the cannula or further relevant complications, likeinfection, extravasation, compartment syndrome, and cannula dislodgment or bleeding were not observed.

Intraosseous devices: a randomized controlled trial comparing three intraosseous devices.

Abstract

INTRODUCTION: Access to the circulation is mandatory for adequate treatment in medical emergency situations. Intraosseous (IO) infusion is a safe, fast, and effective alternative for gaining access to the circulation, if intravenous access fails. In the last decade, the IO method gained renewed interest. New devices have been developed, such as the Bone Injection Gun (BIG) 15G/18G and the First Access for Shock and Trauma 1 (FAST1).

OBJECTIVE: To determine which IO needle is preferable for gaining IO access in patients requiring acute administration of fluids or medication in a prehospital setting.

METHODS: In this single-blind prospective randomized trial, the IO needles were added to the equipment of the helicopter emergency medical services (HEMS) system. The HEMS nurses received training in proper use of all needles. Children (1-13 years) were randomized to the Jamshidi 15G or the BIG 18G, and adults (>or= 14 years) were randomized to the Jamshidi 15G, the BIG 15G, or the FAST1. All patients requiring acute administration of fluids or medication, without successful insertion of an intravenous (IV) catheter, were included. The IO needles were compared in terms of insertion time, success rate, bone marrow aspiration, adverse events during placement, and user satisfaction.

RESULTS: Sixty-five adult and 22 pediatric patients were included. The treatment groups were similar with respect to age, gender, mortality, and trauma mechanism (p >or= 0.05). The median insertion times ranged from 38 seconds for the Jamshidi 15G to 49 seconds for the BIG 15G and 62 seconds for the FAST1 (p = 0.004). The devices did not differ with respect to success rates (adults overall 80% and children overall 86%), complication rates, and user satisfaction.

CONCLUSIONS: The Jamshidi 15G needle could be placed significantly faster than the FAST1. The devices had similar success rates, complication rates, and user-friendliness. Intraosseous devices provide a safe, simple, and fast method for gaining access to the circulation in emergency situations.
