Air Transport of Patients with Pneumothorax: Is Tube Thoracostomy Required Before Flight ?

Braude D et Al. Air Med J. 2014 Jul-Aug;33(4):152-6

Objective: It is conventionally thought that patients with pneumothorax (PTX) require tube thoracostomy (TT) before air medical transport (AMT), especially in unpressurized rotor-wing (RW) aircraft, to prevent deterioration from expansion of the PTX or development of tension PTX. We hypothesize that patients with PTX transported without TT tolerate RW AMT without serious deterioration, as defined by hypotension, hypoxemia, respiratory distress, intubation, bag valve mask ventilation, needle thoracostomy (NT), or cardiac arrest during transport.

Methods: We conducted a retrospective review of a case-series of trauma patients transported to a single Level 1 trauma center via RW with confirmed PTX and no TT. Using standardized abstraction forms, we reviewed charts for signs of deterioration. Those patients identified as having clinical deterioration were independently reviewed for the likelihood that the clinical deterioration was a direct consequence of PTX.

Results: During the study period, 66 patients with confirmed PTX underwent RW AMT with an average altitude gain of 1890 feet, an average barometric pressure 586-600 mmHg, and average flight duration of 28 minutes. All patients received oxygen therapy; 14/66 patients (21%) were supported with positive pressure ventilation. Eleven of 66 patients (17%) had NT placed before flight and 4/66 (6%) had NT placed during flight. Four of 66 patients (6% CI0.3-11.7) may have deteriorated during AMT as a result of PTX; all were successfully managed with NT.

Conclusions: In this series, 6% of patients with PTX deteriorated as result of AMT without TT, yet all patients were managed successfully with NT. Routine placement of TT in patients with PTX before RW AMT may not be necessary. Further prospective evaluation is warranted.

Evaluation of 8.0-cm needle at the fourth anterior axillary line for needle chest decompression of tension pneumothorax

Chang SJ et Al. J Trauma Acute Care Surg. 2014;76: 1029-1034


La décompression d'un thorax sous pression doit maintenant se faire par voie latérale, la voie antérieure étant associée à un taux d'échec important notamment avec l'emploi de cathéters veineux classiques dont la longueur est rarement supérieure à 5 cm. Le recours à des cathéters de 8 cm est ainsi prôné dans la littérature anglo-saxone sur des seuls arguments  anatomiques. Le risque de ponction de structures intrathoraciques est réel et doit rendre mesuré quand au recours à de tels dispositifs. On rappelle que la thoracostomie au doigt doit être considérée comme la référence. 

BACKGROUND: Five-centimeter needles at the second intercostal space midclavicular line (2MCL) have high failure rates for decompression of tension pneumothorax. This study evaluates 8-cm needles directed at the fourth intercostal space anterior axillary line (4AAL).
METHODS: Retrospective radiographic analysis of 100 consecutive trauma patients 18 years or older from January to September 2011. Measurements of chest wall thickness (CWT) and depth to vital structure (DVS) were obtained at 2MCL and 4AAL. 4AAL measurements were taken based on two angles: closest vital structure and perpendicular to the chest wall. Primary outcome measures were radiographic decompression (RD) (defined as CWT G 80 mm) and radiographic noninjury (RNI) (DVS 9
80 mm) of 8-cm needles at 4AAL. Secondary outcome measures are effect of angle of entry on RNI at 4AAL, RD and RNI of 8-cm needles at 2MCL, and comparison of 5-cm needles with 8-cm needles at both locations.
RESULTS: Eighty-four percent of the patients were male, with mean Injury Severity Score (ISS) of 17.7 (range, 1.0Y66.0) and body mass index of 26.8 (16.5Y48.4). Mean CWT at 4AAL ranged from 37.6 mm to 39.9 mm, significantly thinner than mean CWT at 2MCL (43.3Y46.7 mm). Eight-centimeter needle RD was more than 96% at both 4AAL and 2MCL. Five-centimeter RD ranged from 66% to 81% at all sites. Mean DVS at 4AAL ranged from 91.8 mm to 128.0 mm. RNI at all sites was more than 91% except at left 4AAL, when taken to the closest vital structure (mean DVS, 91.8 mm), with 68% RNI. Perpendicular entry
increased DVS to 109.4 mm and subsequent RNI to 91%. Five-centimeter RNI at all sites was more than 99%.


CONCLUSION: CWT at 4AAL is significantly thinner than 2MCL. Based on radiographic measurements, 8-cm catheters have a higher chance of pleural decompression when compared with 5-cm catheters. Steeper angle of entry at 4AAL improves 8-cm noninjury rates to more than 91%. 


Pneumothorax: Passez par le côté

Failed needle decompression of bilateral spontaneous tension pneumothorax

Bac PT et Al. Acta Anaesthesiol Scand. 2015 Apr 21. doi: 10.1111/aas.12538. [Epub ahead of print]


Cet article a le mérite de rappeler que la détresse respiratoire est ua prmeier plan enc as de pneumothorax suffocant chez le patient non ventilé, que la voie latérale doit être privilégié et surtout que la thoracostomie simple est parfaitement efficace.


This case report presents a young male admitted with primary bilateral spontaneous tension pneumothorax and severe respiratory distress. This is an extremely rare condition. The patient was on the verge of hypoxic cardiac arrest and the attempted needle thoracocentesis was unsuccessful. Needle thoracocentesis in the midclavicular line of the second intercostal space is widely used and recommended as first-line treatment of tension pneumothorax. Reviewing the literature, the procedure is not based on solid evidence. It has high failure rates and potentially serious complications. Alternatives to this approach are perhaps more appropriate. Correctly done, needle thoracocentesis has its place in the presence of a diagnosed or suspected tension pneumothorax when no other options are available. If needle thoracocentesis is chosen, then insertion in the mid-anterior axillary line of the 3rd–5th intercostal space is an appropriate alternative site. Otherwise, lateral thoracostomy, with or without chest tube insertion, is a safe procedure with a high success rate. It should be considered as the first-line treatment of tension pneumothorax, particularly in the unstable patient


Pansements 3 côtés: C'est efficace

Vented Chest Seals for Prevention of Tension Pneumothorax in a Communicating Pneumothorax

Kotora JG et Al.  J Emerg Med. 2013 Nov;45(5):686-94.


La prise en charge d'une plaie thoracique soufflante (1est une éventualité peu fréquente qui expose d'une part au risque de détresse respiratoire aiguë et d'autre part au risque d'instabilité hémodynamique en rapport avec le caractère compressif d'un épanchement intra-thoracique gazeux ou liquidien (2) L'exsufflation et/ou la pose d'un pansement 3 côtés sont alors requis. Ce dernier peut être réalisé simplement ou par l'emploi de dispositifs commerciaux prêts à l'emploi. Le travail présenté exprime l'efficacité des pansements "3 côtés" de dernières générations aussi bien en matière d'adhérence cutanée que d'efficacité d'évacuation de l'air et secrétions intra-thoraciques. Ils jouent donc ainsi parfaitement le rôle pour lesquels ils ont été conçus (3).




Tension pneumothorax accounts for 3%–4% of combat casualties and 10% of civilian chest trauma. Air entering a wound via a communicating pneumothorax rather than by the trachea can result in respiratory arrest and death. In such cases, the Committee on Tactical Combat Casualty Care advocates the use of unvented chest seals to prevent respiratory compromise.

OBJECTIVE: A comparison of three commercially available vented chest seals was undertaken to evaluate the efficacy of tension pneumothorax prevention after seal application.


A surgical thoracostomy was created and sealed by placing a shortened 10-mL syringe barrel (with plunger in place) into the wound. Tension pneumothorax was achieved via air introduction through a Cordis to a maximum volume of 50 mL/kg. A 20% drop in mean arterial pressure or a 20% increase in heart rate confirmed hemodynamic compromise. After evacuation, one of three vented chest seals (HyFin ®, n = 8; Sentinel ®, n = 8, SAM ®, n = 8) was applied. Air was injected to a maximum of 50 mL/kg twice, followed by a 10% autologous blood infusion, and finally, a third 50 mL/kg air bolus. Survivors completed all three interventions, and a 15-min recovery period.



The introduction of 29.0 (±11.5) mL/kg of air resulted in tension physiology. All three seals effectively evacuated air and blood. Hemodynamic compromise failed to develop with a chest seal in place.



HyFin ®, SAM ®, and Sentinel ® vented chest seals are equally effective in evacuating blood and air in a communicating pneumothorax model. All three prevented tension pneumothorax formation after penetrating thoracic trauma

Un trocard de coelio ?

Standard laparoscopic trocars for the treatment of tension pneumothorax: A superior alternative to needle decompression

Quinton H. et Al. J Trauma Acute Care Surg. 2014;77: 170-175.


Le recours à un cathéter d'au moins 8 cm est prôné par certains du fait de l'épaisseur de la paroi thoracique. L'inconvénient de cette longueur est le risque non négligeable de ponction parenchymateuse surtout lors de l'emploi de la voie antérieure.


La voie latérale exposerait maoins à ce risque. Une alternative bien moins dangereuse et toute aussi efficace est la thoracostomie au doigt. Et pourquoi pas un trocard de coelio ?


BACKGROUND: Needle thoracostomy (NT) is a commonly taught intervention for tension pneumothorax (tPTX) but has a high failure rate. We hypothesize that standard 5-mm laparoscopic trocars may be a safe and more effective alternative.

Thirty episodes of tPTX and 27 episodes of tension-induced pulseless electrical activity (PEA) were induced in five adult swine using thoracic CO2 insufflation via balloon trocar. Tension was defined as a 50% decrease in cardiac output. Chest decompression was performed with 5-mm laparoscopic trocars for the treatment of both tPTX with hemodynamic compromise and tension-induced PEA. The lungs and heart were inspected and graded at necropsy for trocar-related injury. Results were also compared with success rates with NT in the same model.

The placement of a 5-mm trocar rapidly and immediately relieved tension physiology in 100% of the cases. Mean arterial pressure, cardiac output, central venous pressure, and pulmonary capillary wedge pressure all returned to baseline within 1 minute of trocar placement. Adequate perfusion was restored in 100% of tension-induced PEA cases within 30 seconds of trocar placement. There was no evidence of trocar-related heart or lung damage in any of the experimental animals at necropsy (mean injury scores, 0 for both). Fivemillimeter trocars significantly outperformed standard NT for both tPTX and tension-induced PEA arrest.

tPTX and tension-induced PEA can be safely and effectively treated with chest decompression using 5-mm laparoscopic trocars. This technique may serve as a more rapid and reliable alternative to needle decompression.

Pneumothorax et vol en altitude : Possible ?

Cleared for takeoff: The effects of hypobaric conditions on traumatic pneumothoraces

Majercik S. et All. J Trauma Acute Care Surg. 2014;77: 729-733

La présence d'un pneumothorax traumatique non résolu ne serait pas (ou plus ) une contre-indication à un voyage aérien. C'est ce que suggère ce travail
BACKGROUND: Current guidelines suggest that traumatic pneumothorax (tPTX) is a contraindication to commercial airline travel, and patients should wait at least 2 weeks after radiographic resolution of tPTX to fly. This recommendation is not based on prospective, physiologic study. We hypothesized that despite having a radiographic increase in pneumothorax size while at simulated altitude, patients with a recently treated tPTX would not exhibit any adverse physiologic changes and would not report any symptoms of cardiorespiratory compromise.


METHODS: This is a prospective, observational study of 20 patients (10 in Phase 1, 10 in Phase 2) with tPTX that has been treated by chest tube (CT) or high flow oxygen therapy. CT must have been removed within 48 hours of entering the study. Subjects were exposed to 2 hours of hypobaria (554 mm Hg in Phase 1, 471 mm Hg in Phase 2) in a chamber in Salt Lake City, Utah. Vital signs and subjective symptoms were recorded during the ‘‘flight.’’ After 2 hours, while still at simulated altitude, a portable chest radiograph (CXR) was obtained. tPTX sizes on preflight, inflight, and postflight CXR were compared.


RESULTS: Sixteen subjects (80%) were male. Mean (SD) age and ISS were 49 (5) years and 10.5 (4.6), respectively. Fourteen (70%) had a CT to treat tPTX, which had been removed 19 hours (range, 4Y43 hours) before the study. No subject complained of any cardiorespiratory symptoms while at altitude. Radiographic increase in tPTX size at altitude was 5.6 (0.61) mm from preflight CXR. No subject developed a tension tPTX. No subject required procedural intervention during the flight. Four hours after the study, all tPTX had returned to baseline size.


CONCLUSION: Patients with recently treated tPTX have a small increase in the size of tPTX when subjected to simulated altitude. This is clinically well tolerated. Current prohibitions regarding air travel following traumatic tPTX should be reconsidered and further studied.

Drain thoracique: Confirmation, pas si simple

An audit of the complications of intercostal chest drain insertion in a high volume trauma service in South Africa.

Kong V. et All. Ann R Coll Surg Engl. 2014 Nov;96(8):609-13


Intercostal chest drain (ICD) insertion is a commonly performed procedure in trauma and may be associated with significant morbidity.


This was a retrospective review of ICD complications in a major trauma service in South Africa over a four-year period from January 2010 to December 2013.



drainage thorax

A total of 1,050 ICDs were inserted in 1,006 patients, of which 91% were male. The median patient age was 24 years (interquartile range [IQR]: 20-29 years). There were 962 patients with unilateral ICDs and 44 with bilateral ICDs. Seventy-five per cent (758/1,006) sustained penetrating trauma and the remaining 25% (248/1006) sustained blunt trauma. Indications for ICD insertion were: haemopneumothorax (n=338), haemothorax (n=314), simple pneumothorax (n=265), tension pneumothorax (n=79) and open pneumothorax (n=54). Overall, 203 ICDs (19%) were associated with complications: 18% (36/203) were kinked, 18% (36/203) were inserted subcutaneously, 13% (27/203) were too shallow and in 7% (14/203) there was inadequate fixation resulting in dislodgement. Four patients (2%) sustained visceral injuries and two sustained vascular injuries. Forty-one per cent (83/203) were inserted outside the 'triangle of safety' but without visceral or vascular injuries. One patient had the ICD inserted on the wrong side. Junior doctors inserted 798 ICDs (76%) while senior doctors inserted 252 (24%). Junior doctors had a significantly higher complication rate (24%) compared with senior doctors (5%) (p<0.001). There was no mortality as a direct result of ICD insertion. </sec> Conclusions ICD insertion is associated with a high rate of complications. These complications are significantly higher when junior doctors perform the procedure. A multifaceted quality improvement programme is needed to improve the situation.

Exsufflation: 1 / 4 sans pneumothorax !

Inadequate Needle Thoracostomy Rate in the Prehospital Setting for Presumed Pneumothorax. An Ultrasound Study

Blaivas M.  J Ultrasound Med 2010; 29:1285–1289


Nombreux ont attiré l'attention sur le risque d'inefficacité des exsufflations au cathéter à cause de la longueur de ces derniers, plus court que l'épaisseur de la paroi thoracique. Certains prônent l'emploi de cathéter de plus de 8 cm sans véritablement de fondements scientifiques (Lire cette analyse). Entre des mains peu expérimentées cette pratique apparaît dangereuse du fait du fait des erreurs faites sur les niveaux de ponction, ce d'autant que ces cathéters ne sont pas très efficaces dans le temps. L'article proposé incite encore plus à la nécessaire prudence à avoir avant de faire pénétrer une aiguille dans un thorax. En effet ce geste serait pratiqué 1 fois sur 4 en l'absence de pneumothorax. 


Objective. The purpose of this study was to evaluate the frequency of inadequate needle chest tho-racostomy in the prehospital setting in trauma patients suspected of having a pneumothorax (PTX) onthe basis of physical examination.

Methods. This study took place at a level I trauma center. All trauma patients arriving via emergency medical services with a suspected PTX and a needle thoracostomy were evaluated for a PTX with bedside ultrasound. Patients too unstable for ultrasound evaluation before tube thoracostomy were excluded, and convenience sampling was used. All patients were scanned while supine. Examinations began at the midclavicular line and included the second through fifth ribs. If no sliding lung sign (SLS) was noted, a PTX was suspected, and the lung point was sought for definitive confirmation. When an SLS was noted throughout and a PTX was ruled out on ultrasound imaging, the thoracostomy catheter was removed. Descriptive statistics were calculated.

Results. A total of 57 patients were evaluated over a 3-year period. All had at least 1 needle thoracostomy attempted; 1 patient underwent 3 attempts. Fifteen patients (26%) had a normal SLS on ultrasound examination and no PTX after the thoracostomy catheter was removed. None of the 15 patients were later discovered to have a PTX on subsequent computed tomography. Conclusions. In this study, 26% of patients who received needle thoracostomy in the prehospital setting for a suspected PTX appeared not to have had a PTX originally, nor had 1 induced by the needle thoracostomy. It may be prudent to evaluate such patients with bedside ultrasound instead of automatically converting all needle thoracostomies to tube thoracostomies.


Recourir à l'échographie pleurale et réaliser ce geste par voie latérale avec un cathéter de 5 cm apparaissent être sécuritaire.


Drainage et thoracocentèse

Chest Drainage

McDermott S. et Al. Semin Intervent Radiol 2012;29:247–255

Infectious, traumatic, or neoplastic processes in the chest often result in fluid collections within the pleural, parenchymal, or mediastinal spaces. The same fundamental principles that guide drainages of the abdomen can be applied to the chest. This review discusses various pathologic conditions of the thorax that can result in the abnormal accumulation of fluid or air, and their management using image-guided methods.


Thoracostomie au doigt: Le mieux !

Simple thoracostomy in prehospital trauma management is safe and effective: a 2-year experience by helicopter emergency medical crews

Massaruttia D et Al. Eur J Emerg Med. 2006 Oct;13(5):276-80


La réalisation d'une exsufflation à l'aiguille bien que classique reste discutable du fait de nombreux problèmes techniques et du caractère très relatif de son efficacité. La thoracostomie au doigt doit être considérée comme la technique de référence.



To evaluate the effectiveness and potential complications of simple thoracostomy, as first described by Deakin, as a method for prehospital treatment of traumatic pneumothorax.



Prospective observational study of all severe trauma patients rescued by our Regional Helicopter Emergency Medical Service and treated with on-scene simple thoracostomy, over a period of 25 months, from June 1, 2002 to June 30, 2004.


Fifty-five consecutive severely injured patients with suspected pneumothorax and an average Revised Trauma Score of 9.6+/-2.7 underwent field simple thoracostomy. Oxygen saturation significantly improved after the procedure (from 86.4+/-10.2% to 98.5%+/-4.7%, P<0.05). No difference exists in the severity of thoracic lesions between patients with systolic arterial pressure and oxygen saturation below and above or equal to 90. A pneumothorax or a haemopneumothorax was found in 91.5% of the cases and a haemothorax in 5.1%. No cases of major bleeding, lung laceration or pleural infection were recorded. No cases of recurrent tension pneumothorax were observed. Forty (72.7%) patients survived to hospital discharge.



Prehospital treatment of traumatic pneumothorax by simple thoracostomy without chest tube insertion is a safe and effective technique.

Pneumothorax: Pansement NON OCCLUSIF

Vented versus unvented chest seals for treatment of pneumothorax and prevention of tension pneumothorax in a swine model

Kheirabadi BS et all. J Trauma Acute Care Surg. 2013;75: 150-156

La procédure du sauvetage au combat indique qu'un thorax ouvert ne doit JAMAIS être fermé et qu'un pansement 3 côtés doit être mis en place  pour éviter toute surpression intrathoracique. Ceci diffère du TCCC américain qui recommande l'occlusion de la plaie et la surveillance du blessé à la recherche d'un pneumothorax suffocant. Mais les choses évoluent à la lumière de la remise en question de pratiques pas toujours bien documentées. Le TCCC va proposer le recours non pas à l'emploi d'un pansement 3 côtés consommateur de temps mais à l'utilisation de pansements adhésifs prêts à l'emploi.

L'article présenté montre très clairement l'intérêt de la mise en place de pansement permettant l'évacuation de l'air intrathoracique.


Au delà de l'intérêt des dispositifs prêts à l'emploi avec valve de surpression, il y a le problème du choix du modèle. La procédure du sauvetage au combat propose la valve d'asherman, qui doit être considérée comme obsolète car bien qu'efficace, sa capacité d'adhésion à la peau est perfectible. Il semble que les modèles concurrents (Hyfin Vent Chest Seal, SAM chest seal et Sentinel chest seal) proposés par l'industrie aient la même efficacité


Pneumothorax: Dès 10 mmHg

Physiology and cardiovascular effect of severe tension pneumothorax in a porcine model

Nelson D et all. J Surg Res. 2013 Jun 5. pii: S0022-4804(13)00505-2


Pneumothoraces are relatively common among trauma patients and can rapidly progress to tension physiology and death if not identified and treated. We sought to develop a reliable and reproducible large animal model of tension pneumothorax and to examine the cardiovascular effects during progression from simple pneumothorax to tension pneumothorax.


Ten swine were intubated, sedated, and placed on mechanical ventilation. After a midline celiotomy, a 10-mm balloon-tipped laparoscopic trocar was placed through the diaphragm, and a 28F chest tube was placed in the standard position and clamped. Thoracic insufflation was performed in 5-mm increments, and continuous cardiovascular measurements were obtained.


Mean insufflation pressures of 10 mm Hg were associated with a 67% decrease in cardiac output (6.6 L/min versus 2.2 l/min; P = 0.04). An additional increase in the insufflation pressure (mean 15 mm Hg) was associated with an 82% decrease in cardiac output from baseline (6.8 versus 1.2 L/min; P < 0.01). Increasing insufflation pressures were associated with a corresponding increase in central venous pressure (from 7.6 mm Hg to 15.2 mm Hg; P < 0.01) and a simultaneous decrease in the pulmonary artery diastolic pressure (from 15 mm Hg to 12 mm Hg; P = 0.06), with the central venous pressure and pulmonary artery diastolic pressure approaching equalization immediately before the development of major hemodynamic decline. Pulseless electrical activity arrest was induced at an average of 20 mm Hg. Tension physiology was immediately reversible with adequate decompression, allowing for multiple repeated trials.





A reliable and highly reproducible model was created for severe tension pneumothorax in a large animal. Major cardiovascular instability proceeding to pulseless electrical activity arrest with stepwise insufflation was noted. This model could be highly useful for studying new diagnostic and treatment modalities for tension pneumothorax.

Exsufflation à l'aiguille: Pas si efficace ?

Does needle thoracostomy provide adequate and effective decompression of tension pneumothorax ?

Martin M et All.J Trauma Acute Care Surg. 2012;00: 00Y00 (DOI: 10.1097/TA.0b013e31825ac511) 

Il existe un grand débat sur les modalités d'exsufflation d'un pneumothorax suffocant (site de ponction, longueur et calibre de l'aiguille, thoracostomie au doigt, drainage ?).

Ce travail expérimental pointe du doigt, UNE FOIS DE PLUS, les limites de l'exsuffflation à l'aguille:

"All NTs were patent on initial placement, but 5 (26%) demonstrated mechanical failure (due to kinking, obstruction, or dislodgment) within 5 minutes of placement, all associated with hemodynamic decline. Among the 14 NTs that remained patent at 5 minutes, 6 (43%) failed to relieve tension physiology for an overall failure rate of 58%"


Ces données doivent pousser plus avant la formation vers les deux autres moyens que sont l'exsufflation au doigt (présenté par beaucoup comme la méthode de référence) et bien sûr le drainage thoracique.

Pneumothorax: La sonde d'écho à quel endroit ?

 Anatomical distribution of traumatic pneumothoraces on chest computed tomography: implicationsfor ultrasound screening in the ED

Mennicke M et alll. Am J Emerg Med 2012 Sep;30(7):1025-31

Un travail qui précise les zones optimales d'exploration de la région thoracique pour l'identiifcation optimale des pneumothorax traumatiques.



We sought to assess the anatomical distribution of traumatic pneumothoraces (PTXs) on chest computed tomography (CT) to develop an optimized protocol for PTX screening with ultrasound in the emergency department (ED).


We performed a retrospective review of all chest CTs performed in one ED between January 2005 and December 2008 according to presence, location, and size of PTX. Pneumothoraces were then measured and categorized into 14 anatomical regions for each hemithorax.


A total of 277 (3.8%) PTXs were identified, with 26 bilateral PTX, on 3636 chest CTs performed during the study period. Etiology was blunt (85%) or penetrating trauma (15%). Eighty-three (45%) PTXs were radiographically occult on initial chest x-ray. One hundred eighty-three (66%) PTX had no chest tube at the time of CT. For both hemithoraces, the distribution demonstrated increasing PTX frequency and size from lateral to medial and from superior to inferior. Region 12 (parasternal, intercostal spaces [ICS] 7-8) was involved in 68% of PTX on either side; region 9 (parasternal, ICS 5-6), in 67% on the left and in 52% on the right; and region 11 (lateral to midclavicular line, ICS 7-8), in 46% on the left and in 53% on the right. The largest anterior-to-posterior PTX dimension was seen in region 12.

Our results indicate that 80.4% of right- and 83.7% of left-sided traumatic PTXs would be identified by scanning regions 9, 11, and 12. These findings suggest that a standardized protocol for PTX screening with ultrasound should include these regions.

Drainage Thoracique: Histoire de drain

A portable thoracic closed drainage instrument for hemopneumothorax.J Trauma. 2012;72: 671–675 Tang H; Pan T MD et all.

La pose d'un drain thoracique en préhospitalier s'impose dès lors qu'un pneumothorax n'est pas traité de manière correcte par une thoracostomie au doigt/Exsufflation à l'aiguille ou si l'évacuation du blessé est retardée. Le Front Line Chest Tube est l'équipement préconisé par la procédure du sauvetage au combat. Une alternative de fortune peut être une sonde d'intubation ou une canule de trachétomie. Cet article illustre le travail de réflexion fait pour mettre à disposition un équipement adapté au contexte pré-hopsitalier notamment militaire.  L'emploi de tubes à ballonet est proposé par des auteurs chinois qui ont dévelopé ce nouveau matériel présenté dans le Journal of Trauma
