Prehospital management of chest injuries in severely injured patients-a systematic review and clinical practice guideline update. Eur J Trauma Emerg Surg 2024:10.1007/s00068-024-02457-3. [PMID: 38308661 DOI: 10.1007/s00068-024-02457-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/09/2024] [Accepted: 01/22/2024] [Indexed: 02/05/2024]
Abstract
PURPOSE Our aim was to review and update the existing evidence-based and consensus-based recommendations for the management of chest injuries in patients with multiple and/or severe injuries in the prehospital setting. This guideline topic is part of the 2022 update of the German Guideline on the Treatment of Patients with Multiple and/or Severe Injuries. METHODS MEDLINE and Embase were systematically searched to May 2021. Further literature reports were obtained from clinical experts. Randomised controlled trials, prospective cohort studies, cross-sectional studies, and comparative registry studies were included if they compared interventions for the detection and management of chest injuries in severely injured patients in the prehospital setting. We considered patient-relevant clinical outcomes such as mortality and diagnostic test accuracy. Risk of bias was assessed using NICE 2012 checklists. The evidence was synthesised narratively, and expert consensus was used to develop recommendations and determine their strength. RESULTS Two new studies were identified, both investigating the accuracy of in-flight ultrasound in the detection of pneumothorax. Two new recommendations were developed, one recommendation was modified. One of the two new recommendations and the modified recommendation address the use of ultrasound for detecting traumatic pneumothorax. One new good (clinical) practice point (GPP) recommends the use of an appropriate vented dressing in the management of open pneumothorax. Eleven recommendations were confirmed as unchanged because no new high-level evidence was found to support a change. CONCLUSION Some evidence suggests that ultrasound should be considered to identify pneumothorax in the prehospital setting. Otherwise, the recommendations from 2016 remained unchanged.

Abstract
BACKGROUND ATLS suggests simple thoracostomy (ST) after failure of needle thoracostomy (NT) in thoracic trauma. Some EMS agencies have adopted ST into their practice. We sought to describe our experience implementing ST in the prehospital setting, hypothesizing that prehospital ST would reduce failure rates and improve outcomes compared to NT. METHODS This was a retrospective review of adult trauma patients who received prehospital ST or NT from 2017 to 2020. RESULTS There were 48 patients with 64 procedures included. 83.7% were male and 65.8% injured by penetrating mechanism and of median (IQR) age of 31 (25-46) years. 28 (43.8%) procedures were NT and 36 (56.3%) were ST. Rates of improved patient response (P = .15), noted return of blood/air (P = .19), and return of spontaneous circulation (P = .62) did not differ. On-scene times were higher for ST (16.8 vs 11.5 minutes; P < .02). Overall mortality did not differ between ST and NT (68.2% vs 46.4%, respectively; P = .125). For patients that survived beyond the ED, procedure-related complication rates were 2 of 21 patients (9.5%) in ST and 1 of 12 (8.3%) in NT. In penetrating trauma, simple thoracostomy had longer on-scene time and total prehospital time. DISCUSSION ST did not improve success rates of ROSC and was associated with prolonged prehospital times, especially in penetrating trauma patients. Given the benefit of "scoop and run" in urban penetrating trauma, consideration should be given to direct transport in lieu of ST. Use of ST in blunt trauma should be evaluated prospectively.

Abstract
BACKGROUND Prehospital chest decompression can be a lifesaving procedure in severe chest trauma. Studies investigating prehospital chest decompression are mostly European where physicians are assigned to prehospital care units. This report is one of the first to compare demographics and outcomes in patients undergoing prehospital chest decompression by trained aeromedical nonphysician personnel to hospital chest decompression by physicians. METHODS Prehospital tube thoracostomy (PTT) patients were identified from January 2014 to January 2019 and were matched in a 1:2 ratio based on age, Injury Severity Score (ISS), and chest Abbreviated Injury Score (AIS) to patients who underwent hospital tube thoracostomy (HTT) within 24 hours of admission. RESULTS Forty-nine PTT patients were matched to 98 HTT patients. PTT patients had lower admission Glasgow Coma Scale (GCS), a higher rate of pre-chest tube needle decompression, and higher level 1 trauma activation. PTT were placed sooner (21.9 vs 157.0 minutes, P < .001). Rates of tube malposition, organ injury, tube dislodgement, empyema, and hospital-acquired pneumonia over the course of hospital admission were not significantly different between the 2 groups. PTT patients had longer intensive care unit length of stay (LOS), but similar hospital LOS, and overall mortality. DISCUSSION This report demonstrates that PTT is performed sooner than hospital placed tubes. Complication rates associated with tube thoracostomy and patient outcomes were not statistically different between PTT and HTT groups.

Abstract
Objective To compare the anterior with lateral mean chest wall thickness measured by bedside ultrasound in Chinese adults in order to suggest a preferred site for needle decompression in tension pneumothorax. Study design This was an observational cross-sectional study conducted in a regional hospital over three months. Subjects were recruited by convenience sampling. Chest wall thickness at the second intercostal space, mid clavicular line, fifth intercostal space, anterior axillary line and fifth intercostal space and mid axillary line was measured using ultrasound on both sides. Range, mean values and confidence intervals were calculated. Results One-hundred and fourteen subjects were recruited. The mean anterior chest wall thickness was 2.62 cm (at second intercostal space, mid-clavicular line) and mean lateral chest wall was 2.68 cm (at fifth intercostal space, anterior axillary line) and 2.87 cm (at fifth intercostal space and mid-axillary line) respectively. Chest wall thickness at fifth intercostal space and mid-axillary line was significantly greater than second intercostal space, mid-clavicular line ( p < 0.01). Chest wall thickness was greater than 5 cm in 3.5% of the study population. Conclusion There is a need for population-based guidelines. We recommend needle decompression at the second intercostal space, mid-clavicular line with a 50-mm angiocath for Chinese patients with tension pneumothorax. A lateral approach at the fifth intercostal space, anterior axillary line may be considered as an alternative in case of failure. Prehospital point-of-care ultrasound may be a useful adjunct in managing such patients.

Abstract
Trauma-related deaths are not only a relevant medical problem but also a socioeconomic one. The care of a polytraumatized patient is one of the less commonly occurring missions in the rescue and emergency medical services. The aim of this article is to compare the similarities and differences between different course concepts and guidelines in the treatment of trauma-related cardiac arrests (TCA) and to filter out the main focus of each concept. Because of the various approaches in the treatment of polytraumatized patients, there are decisive differences between trauma-related cardiac arrests and cardiac arrests from other causes.

Abstract
We report a rare but serious complication of needle thoracostomy, penetration of the myocardium. Needle thoracostomy is typically performed in the prehospital setting or upon arrival in the emergency department for suspected tension pneumothorax. Needle decompression is generally taught and done anteriorly, in the 2nd intercostal space on the midclavicular line (MCL). An alternative approach is laterally, along the anterior axillary line (AAL) in the 4th intercostal space. Our case supports prior literature that the anterior MCL location has a low rate of efficacy to decompress the chest, as well as a high rate of complications. We recommend performing needle decompression laterally at the AAL whether in the field or in the emergency department.

Abstract
The survival rate of penetrating cardiac trauma is dismal, with only a few patients reaching the hospital with any signs of life. Short transport time and close proximity to the trauma center are positive factors for survival. We report the successful case of a 21-year-old male with penetrating cardiac injury and tension-pneumothorax with long distance to a trauma facility. The patient was stabbed twice in the anterior left side of the thorax. The emergency services found the patient with suspicion of left tension-pneumothorax. Urgent left mini-thoracotomy was established resulting in spontaneous respiration and clinical improvement. Due to rapid clinical deterioration and clinical suspicion of pericardial tamponade, patient was transported to the local regional hospital only minutes away. Echocardiography confirmed tamponade, and urgent ultrasound-guided pericardiocentesis was performed. During the transport blood was intermittently drained from the pericardial sack until arrival at the trauma center where a penetrating injury to the left ventricle was repaired during urgent cardiac surgery. The patient was discharged 8 days after the incident. Conclusion. Well organized emergency medical transport systems increase the chance of survival in penetrating cardiac injuries. Urgent pericardiocentesis with continuous drainage can help stabilize a patient until arrival at trauma facility.

Abstract
BACKGROUND Although needle decompression of tension pneumothorax through the second intercostal space in the midclavicular line (Monaldi's approach) is a life-saving procedure, severe complications have been reported after its implementation. We evaluated the procedure by comparing how it was performed on cadavers by study participants with different training levels. METHODS Six participants including one thoracic surgeon performed bilateral thoracic drainage after Monaldi on 82 torsos. After the thoraces were opened, the distances from the internal thoracic artery (A), the site of the puncture (B) and the midclavicular line (C) were measured bilaterally with reference to the median of the sternum. Further, it was determined whether the participants had correctly identified the second intercostal space. The differences between B-A and C-B were analysed. RESULTS The needle was placed in the second intercostal space in 136 hemithoraces (83%). The thoracic surgeon showed a hit rate of 0% laceration of adjacent vessels. All the other participants had hit rates between 10% and 15%. The interval B-A ranged from 2.88 to 5.06cm in right and from 3.00 to 5.00cm in left hemithoraces. The distance C-B lay between 1.03cm and 1.87cm (right side), and 0.84cm and 2.02cm (left side). CONCLUSION In our collective, the main problem was failure to assess correctly the lateral extension of the clavicle. If this fact is emphasized during training, Monaldi's approach is a safe method for needle decompression of pneumothorax.

Abstract
Trauma is the leading cause of death worldwide. Approximately 2/3 of the patients have a chest trauma with varying severity from a simple rib fracture to penetrating injury of the heart or tracheobronchial disruption. Blunt chest trauma is most common with 90% incidence, of which less than 10% require surgical intervention of any kind. Mortality is second highest after head injury, which underlines the importance of initial management. Many of these deaths can be prevented by prompt diagnosis and treatment. What is the role of the thoracic surgeon in the management of chest trauma in severely injured patients? When should the thoracic surgeon be involved? Is there a place for minimal invasive surgery in the management of severely injured patients? With two case reports we would like to demonstrate how the very specific knowledge of thoracic surgeons could help in the care of trauma patients.

Abstract
Chest trauma remains an issue for health services for both severe and apparently mild trauma management. Severe chest trauma is associated with high mortality and is considered liable for 25% of mortality in multiple traumas. Moreover, mild trauma is also associated with significant morbidity especially in patients with preexisting conditions. Thus, whatever the severity, a fast-acting strategy must be organized. At this time, there are no guidelines available from scientific societies. These expert recommendations aim to establish guidelines for chest trauma management in both prehospital an in hospital settings, for the first 48hours. The "Société française d'anesthésie réanimation" and the "Société française de médecine d'urgence" worked together on the 7 following questions: (1) criteria defining severity and for appropriate hospital referral; (2) diagnosis strategy in both pre- and in-hospital settings; (3) indications and guidelines for ventilatory support; (4) management of analgesia; (5) indications and guidelines for chest tube placement; (6) surgical and endovascular repair indications in blunt chest trauma; (7) definition, medical and surgical specificity of penetrating chest trauma. For each question, prespecified "crucial" (and sometimes also "important") outcomes were identified by the panel of experts because it mattered for patients. We rated evidence across studies for these specific clinical outcomes. After a systematic Grade® approach, we defined 60 recommendations. Each recommendation has been evaluated by all the experts according to the DELPHI method.

Abstract
Chest drain placement is one of the most common surgical procedures performed in routine clinical practice. Despite the many benefits, chest tube insertion is not always a harmless procedure, and potential significant morbidity and mortality may exist. The aim of this article was to highlight the correct chest tube placement procedure and to focus on errors and clinical complications following its incorrect insertion into the chest.

Abstract
INTRODUCTION Chest decompression can be performed by different techniques, like needle thoracocentesis (NT), lateral thoracostomy (LT), or tube thoracostomy (TT). The aim of this study was to report the incidence of prehospital chest decompression and to analyse the effectiveness of these techniques. MATERIAL AND METHODS In this retrospective case series study, all medical records of adult trauma patients undergoing prehospital chest decompression and admitted to the resuscitation area of a level-1 trauma center between 2009 and 2015 were reviewed and analysed. Only descriptive statistics were applied. RESULTS In a 6-year period 24 of 2261 (1.1%) trauma patients had prehospital chest decompression. Seventeen patients had NT, six patients TT, one patient NT as well as TT, and no patients had LT. Prehospital successful release of a tension pneumothorax was reported by the paramedics in 83% (5/6) with TT, whereas NT was effective in 18% only (3/17). In five CT scans all thoracocentesis needles were either removed or extrapleural, one patient had a tension pneumothorax, and two patients had no pneumothorax. No NT or TT related complications were reported during hospitalization. CONCLUSION Prehospital NT or TT is infrequently attempted in trauma patients. Especially NT is associated with a high failure rate of more than 80%, potentially due to an inadequate ratio between chest wall thickness and catheter length as previously published as well as a possible different pathophysiological cause of respiratory distress. Therefore, TT may be considered already in the prehospital setting to retain sufficient pleural decompression upon admission.

‘The pre-hospital management of chest injury: a consensus statement’ was originally published by the Faculty of Pre-hospital Care, Royal College of Surgeons of Edinburgh in 2007. To update the pre-existing guideline, a consensus meeting of stakeholders was held by the Faculty of Pre-hospital Care in Coventry in November 2013. This paper provides a guideline for the pre-hospital management of patients with the life-threatening chest injuries of tension pneumothorax, open pneumothorax, massive haemothorax, flail chest (including multiple rib fractures), and cardiac tamponade.

Abstract
BACKGROUND Thoracocentesis is a simple procedure with high potential to be life-saving, but is associated with complications if performed incorrectly. The aim of this study was to determine both the ability and confidence of practitioners who would be expected deal with a tension pneumothorax both in and out of hospital. If any shortfall was identified between theoretical and practical knowledge the goal was to develop techniques to overcome that shortfall. METHODS A total of 51 consenting medical practitioners were recruited to participate in a prospective single-subject crossover applied behavioural analysis study. The primary outcome was the change in accuracy of identification of the correct site for needle thoracocentesis on an anatomical diagram and by verbal description. This was compared before and after the introduction of brief and frequent "life-saving practical skills" training sessions. Participants' confidence was also assessed pre and post intervention. RESULTS There was a disparity pre-intervention between confidence (79.4% felt able to perform the procedure without assistance) and competence (85.2% of these incorrectly identified the anatomical site). Following intervention, the in-practice correct identification of the site increased from 15.7% to 52.9%. The disparity between confidence and competence still existed by was reduced. CONCLUSIONS The learning and re-learning of this skill should occur regularly through both theoretical and practical teaching to ensure the adequate ability of practitioners and reduce the danger associated with false confidence.

Abstract
BACKGROUND Tension pneumothorax is one of the leading causes of preventable death in both military and civilian trauma patients. Needle decompression is recommended in trauma guidelines as an emergency procedure to relieve increased intrapleural pressure. The main reason for decompression failure is reported to be insufficient needle length in proportion to the chest wall thickness (CWT). So far, population-based epidemiologic data on CWT are missing. Therefore, it was the aim of this work to investigate the CWT in the second intercostal space, midclavicular line, based on magnetic resonance imaging data of a large population-based sample. The second aim of this study was to explore the potential risk of iatrogenic lesions caused by the proximity of the intended puncture track to the internal mammary artery. METHODS A total of 2,574 healthy volunteers (mean [SD] age, 53.3 [13.9] years; range, 21-89 years) from the population-based cohort Study of Health in Pomerania (SHIP) were enrolled. CWT and the distance from the intended puncture track to the internal mammary artery were investigated with the chest sequences of a standardized 1.5-T whole-body magnetic resonance imaging. RESULTS For all 5,148 measured sites in 2,574 volunteers, the mean (SD) CWT was 5.1 (1.4) cm. The mean body mass index was determined to be 27.7 kg/m. The CWT correlated significantly with body weight and body mass index. The internal mammary artery was located medial to the intended puncture site in all participants; the mean (SD) distance was 5.7 (0.7) cm on the right and 5.5 (0.7) cm on the left side. CONCLUSION Based on the population-based epidemiologic data presented in this study, the use of a needle of 7 cm in length is recommended to decompress a tension pneumothorax in the second intercostal space in the midclavicular line, which might successfully decompress more than 90% of the participants in this study. When using this anterior approach at the anatomically correct puncture site, safety margin to the internal mammary artery is sufficient so that the risk of iatrogenic lesion of the internal mammary artery should be minimal. LEVEL OF EVIDENCE Therapeutic/care management study, level IV.

Abstract
PURPOSE OF REVIEW Chest tube placement, or tube thoracostomy, is an invasive procedure designed to evacuate air and/or fluid from the thorax, whether emergent or elective. In the placement of these devices particular attention and effort must be made to understand safe and reliable anatomic techniques and device maintenance so as to avoid serious injury to the patient. This review focuses on complications of chest tube placement, with the emphasis on patient safety and error prevention. RECENT FINDINGS There is a paucity of high-quality recent literature on tube thoracostomy complications. With the advent of value-driven healthcare, increasing emphasis is being placed on appropriate procedural indications, procedural safety, and patient satisfaction. Good clinical outcomes are critical to achieve and maintain in this context. SUMMARY Given the high volume of tube thoracostomies globally, greater awareness of potential complications and preventive strategies is needed. The authors attempt to bridge this important gap.

Abstract
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.

Abstract
Needle thoracostomy (NT) is a valuable adjunct in the management of tension pneumothorax (tPTX), a life-threatening condition encountered mainly in trauma and critical care environments. Most commonly, needle thoracostomies are used in the prehospital setting and during acute trauma resuscitation to temporize the affected individuals prior to the placement of definitive tube thoracostomy (TT). Because it is both an invasive and emergent maneuver, NT can be associated with a number of potential complications, some of which may be life-threatening. Due to relatively common use of this procedure, it is important that healthcare providers are familiar, and ready to deal with, potential complications of NT.

Abstract
BACKGROUND Point of injury needle thoracostomy (NT) for tension pneumothorax is potentially lifesaving. Recent data raised concerns regarding the efficacy of conventional NT devices. Owing to these considerations, the Israeli Defense Forces Medical Corps (IDF-MC) recently introduced a longer, wider, more durable catheter for the performance of rapid chest decompression. The present series represents the IDF-MC experience with chest decompression by NT. METHODS We reviewed the IDF trauma registry from January 1997 to October 2012 to identify all cases in which NT was attempted. RESULTS During the study period a total of 111 patients underwent chest decompression by NT. Most casualties (54%) were wounded as a result of gunshot wounds (GSW); motor vehicle accidents (MVAs) were the second leading cause (16%). Most (79%) NTs were performed at the point of injury, while the rest were performed during evacuation by ambulance or helicopter (13% and 4%, respectively). Decreased breath sounds on the affected side were one of the most frequent clinical indications for NT, recorded in 28% of cases. Decreased breath sounds were more common in surviving than in nonsurviving patients. (37% v. 19%, p < 0.001). A chest tube was installed on the field in 35 patients (32%), all after NT. CONCLUSION Standard NT has a high failure rate on the battlefield. Alternative measures for chest decompression, such as the Vygon catheter, appear to be a feasible alternative to conventional NT.

Abstract
INTRODUCTION Traumatic tension pneumothorax (TPTX) is a life threatening condition, but literature describing this condition specifically in developing countries is scarce. MATERIALS AND METHODS We conducted a retrospective review of 115 patients with a TPTX, managed over a 4-year period in a high volume trauma service in South Africa. RESULTS A total of 118 TPTXs were identified in 115 patients. Eighty-nine percent (102/115) were males, and the mean age was 26 years (SD ± 6 years). Seventy-four percent (87/118) of all TPTXs occurred on the left side. The mechanisms of injury were penetrating in 71 % (82/115) [82 stab injuries], and blunt in 29 % (33/115) [31 road traffic accidents and 2 assaults]. Ninety-seven percent (111/115) of patients presented directly to our unit, while 3 % (4/115) were referrals from other hospitals. Fifteen percent (17/115) of needle decompressions were performed in the pre-hospital setting while the remaining 85 % (98/115) were performed on arrival (73 were recognised clinically and 25 were not). Of the 25 TPTXs that were not recognised clinically on initial assessment, 12 were discovered on CXR, 8 on CT scans and 5 in the operating room (OR). The overall mortality was 9 % (10/115) [7 in CXR, 2 in CT, 1 in OR]. None of the patients who had the TPTXs identified on initial clinical assessment died (0/73), compared with those who were missed on initial clinical assessment, in which the mortality was significantly higher at 40 % (10/25), (p < 0.001). CONCLUSIONS Penetrating injuries accounted for the majority of TPTXs seen in our setting. Clinical recognition of the entity may be challenging and delayed recognition is associated with significant mortality.

Abstract
AbstractIntroductionNeedle thoracostomy is the prehospital treatment for tension pneumothorax. Sufficient catheter length is necessary for procedural success. The authors of this study determined minimum catheter length needed for procedural success on a percentile basis.MethodsA meta-analysis of existing studies was conducted. A Medline search was performed using the search terms: needle decompression, needle thoracentesis, chest decompression, pneumothorax decompression, needle thoracostomy, and tension pneumothorax. Studies were included if they published a sample size, mean chest wall thickness, and a standard deviation or confidence interval. A PubMed search was performed in a similar fashion. Sample size, mean chest wall thickness, and standard deviation were found or calculated for each study. Data were combined to create a pooled dataset. Normal distribution of data was assumed. Procedural success was defined as catheter length being equal to or greater than the chest wall thickness.ResultsThe Medline and PubMed searches yielded 773 unique studies; all study abstracts were reviewed for possible inclusion. Eighteen papers were identified for full manuscript review. Thirteen studies met all inclusion criteria and were included in the analysis. Pooled sample statistics were: n=2,558; mean=4.19 cm; and SD=1.37 cm. Minimum catheter length needed for success at the 95th percentile for chest wall size was found to be 6.44 cm.DiscussionA catheter of at least 6.44 cm in length would be required to ensure that 95% of the patients in this pooled sample would have penetration of the pleural space at the site of needle decompression, and therefore, a successful procedure. These findings represent Level III evidence.ClemencyBM, TanskiCT, RosenbergM, MayPR, ConsiglioJD, LindstromHA. Sufficient catheter length for pneumothorax needle decompression: a meta-analysis.

Abstract
OBJECTIVE In accordance with Boyle's law (as barometric pressure decreases, gas volume increases), thoracostomy is often recommended for patients with pneumothoraces before helicopter EMS (HEMS) transport. We sought to characterize altitude-related volume changes in a pneumothorax model, aiming to improve clinical decisions for preflight thoracostomy in HEMS patients. METHODS This prospective study used 3 devices to measure air expansion at HEMS altitudes. The main device was an artificial pneumothorax model that mimicked a human pulmonary system with a 40 mL pneumothorax. In addition, volume changes were calculated in 2 spherical balloons (6 L and 25 L) by measuring equatorial circumferences. Measurements were recorded at 500-foot altitude increments from 1000 to 5000 feet above ground level. RESULTS The 3 models exhibited volume increases of 12.7%-16.2% at 5000 feet compared to ground level. Univariate linear regression yielded similar increases, 1.27%-1.52%, in volume per 500-foot altitude increase for all 3 models. Bivariate indexed linear regression identified no association between volume increase and assessment model (P values .19 and .29). Locally weighted scatterplot smoothing (lowess) plots indicated linearity of the altitude-volume relationship. CONCLUSION This study demonstrated predictable pneumothorax volume changes at typical HEMS altitudes. Increased understanding of altitude-related volume changes will aid decision making before transport.

Abstract
BACKGROUND Although health care providers utilize classically described signs and symptoms to diagnose tension pneumothorax, available literature sources differ in their descriptions of its clinical manifestations. Moreover, while the clinical manifestations of tension pneumothorax have been suggested to differ among subjects of varying respiratory status, it remains unknown if these differences are supported by clinical evidence. Thus, the primary objective of this study is to systematically describe and contrast the clinical manifestations of tension pneumothorax among patients receiving positive pressure ventilation versus those who are breathing unassisted. METHODS/DESIGN We will search electronic bibliographic databases (MEDLINE, PubMed, EMBASE, and the Cochrane Database of Systematic Reviews) and clinical trial registries from their first available date as well as personal files, identified review articles, and included article bibliographies. Two investigators will independently screen identified article titles and abstracts and select observational (cohort, case-control, and cross-sectional) studies and case reports and series that report original data on clinical manifestations of tension pneumothorax. These investigators will also independently assess risk of bias and extract data. Identified data on the clinical manifestations of tension pneumothorax will be stratified according to whether adult or pediatric study patients were receiving positive pressure ventilation or were breathing unassisted, as well as whether the two investigators independently agreed that the clinical condition of the study patient(s) aligned with a previously published tension pneumothorax working definition. These data will then be summarized using a formal narrative synthesis alongside a meta-analysis of observational studies and then case reports and series where possible. Pooled or combined estimates of the occurrence rate of clinical manifestations will be calculated using random effects models (for observational studies) and generalized estimating equations adjusted for reported potential confounding factors (for case reports and series). DISCUSSION This study will compile the world literature on tension pneumothorax and provide the first systematic description of the clinical manifestations of the disorder according to presenting patient respiratory status. It will also demonstrate a series of methods that may be used to address difficulties likely to be encountered during the conduct of a meta-analysis of data contained in published case reports and series.

Abstract
BACKGROUND Obesity increases the incidence of mortality in trauma patients. Current Advanced Trauma Life Support guidelines recommend using a 5-cm catheter at the second intercostal (ICS) space in the mid-clavicular line to treat tension pneumothoraces. Our study purpose was to determine whether body mass index (BMI) predicted the catheter length needed for needle thoracostomy. METHODS We retrospectively reviewed trauma patients undergoing chest computed tomography scans January 2004 through September 2006. A BMI was calculated for each patient, and the chest wall thickness (CWT) at the second ICS in the mid-clavicular line was measured bilaterally. Patients were grouped by BMI as underweight (≤ 18.5 kg/m2), normal weight (18.6-24.9 kg/m(2)), overweight (25-29.9 kg/m(2)), or obese (≥ 30 kg/m(2)). RESULTS Three hundred twenty-six patients were included in the study; 70% were male. Ninety-four percent of patients experienced blunt trauma. Sixty-three percent of patients were involved in a motor vehicle collision. The average BMI was 29 [SD 7.8]. The average CWT was 6.2 [SD 1.9]cm on the right and 6.3 [SD 1.9]cm on the left. As BMI increased, a statistically significant (p<0.0001) CWT increase was observed in all BMI groups. There were no significant differences in ISS, ventilator days, ICU length of stay, or overall length of stay among the groups. CONCLUSION As BMI increases, there is a direct correlation to increasing CWT. This information could be used to quickly select an appropriate needle length for needle thoracostomy. The average patient in our study would require a catheter length of 6-6.5 cm to successfully decompress a tension pneumothorax. There are not enough regionally available data to define the needle lengths needed for needle thoracostomy. Further study is required to assess the feasibility and safety of using varying catheter lengths.

Improvement in the prehospital recognition of tension pneumothorax: the effect of a change to paramedic guidelines and education. Injury 2014; 45:71-6. [PMID: 23859653 DOI: 10.1016/j.injury.2013.06.010] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/17/2013] [Revised: 04/16/2013] [Accepted: 06/09/2013] [Indexed: 02/02/2023]
Abstract
INTRODUCTION An audit of ambulance service clinical records from 2001 to 2002 in Melbourne, Australia revealed 10 patients with tension pneumothorax on arrival at hospital which had been undetected or untreated by paramedics. The clinical practice guideline for paramedic recognition of tension pneumothorax was subsequently changed to emphasise heightened clinical suspicion of a tension pneumothorax in the setting of chest trauma, especially when patients were managed with positive pressure ventilation. This study was undertaken to determine whether the number of undetected or untreated tension pneumothoraces had decreased after the new clinical practice guideline and associated education program; if there were unintended consequences arising from earlier paramedic intervention; and what effect, if any, this change had on subsequent hospital treatment. METHODS Retrospective case note review of all patients requiring intercostal catheter (ICC) insertion at The Alfred Hospital, Melbourne, Australia, using records from Ambulance Victoria, the Alfred Trauma Registry and the National Coronial Information System. RESULTS In 2001-2002 paramedics treated 22 patients with suspected tension pneumothorax before transport to the Alfred Hospital. In 2006-2007 this number had increased to 81. There was a decrease from ten to four in the number of unrecognised or untreated tension pneumothoraces between the two time periods. No unintended or adverse consequences of prehospital needle decompression could be found. However, there was an increase in the number of patients who had prehospital needle decompression that needed further treatment for tension pneumothorax on arrival at hospital. This need for further treatment was associated with use of shorter cannulas and unilateral needle decompression by paramedics. CONCLUSION A small change in clinical practice guidelines, supported by an education and audit program, led to a reduction in unrecognised untreated tension pneumothoraces by paramedics without an increase in complications. Paramedics should be aware that a shorter cannula may fail to reach the pleural space and that both sides of the chest may require decompression.

Vented versus unvented chest seals for treatment of pneumothorax and prevention of tension pneumothorax in a swine model. J Trauma Acute Care Surg 2013; 75:150-6.

Abstract
BACKGROUND Unvented chest seals (CSs) are currently recommended for the management of penetrating thoracic injuries in the battlefield. Since no supporting data exist, we compared the efficacy of a preferred unvented with that of a vented CS in a novel swine model of pneumothorax (PTx). METHODS An open chest wound was created in the left thorax of spontaneously air-breathing anesthetized pigs (n = 8). A CS was applied over the injury, then tension PTx was induced by incremental air injections (0.2 L) into the pleural cavity via a cannula that was also used to measure intrapleural pressure (IP). Both CS were tested on each pig in series. Tidal volume (V(T)), respiratory rate, IP, heart rate, mean arterial pressure, cardiac output, central venous pressure, pulmonary arterial pressure, venous and peripheral oxygen saturations (SvO2, SpO2) were recorded. Tension PTx was defined as a mean IP equal to or greater than +1 mm Hg plus significant (20-30%) deviation in baseline levels of the previously mentioned parameters and confirmed by chest x-ray study. PaO2 and PaCo2 were also measured. RESULTS PTx produced immediate breathing difficulty and significant rises in IP and pulmonary arterial pressure and falls in V(T), SpO2, and SvO2. Both CSs returned these parameters to near baseline within 5 minutes of application. After vented CS was applied, serial air injections up to 2 L resulted in no significant change in the previously mentioned parameters. After unvented CS application, progressive deterioration of all respiratory parameters and onset of tension PTx were observed in all subjects after approximately 1.4-L air injection. CONCLUSION Both vented and unvented CSs provided immediate improvements in breathing and blood oxygenation in our model of penetrating thoracic trauma. However, in the presence of ongoing intrapleural air accumulation, the unvented CS led to tension PTx, hypoxemia, and possible respiratory arrest, while the vented CS prevented these outcomes.

Abstract
INTRODUCTION The primary goal of this study was to compare the chest wall thicknesses (CWT) at the 2nd intercostal space (ICS) at the mid-clavicular line (MCL) and 5th ICS at the mid-axillary line (MAL) in a population of patients with a CT confirmed pneumothorax (PTX). This result will help physicians to determine the optimum needle thoracostomy (NT) puncture site in patients with a PTX. MATERIALS AND METHODS All trauma patients who presented consecutively to A&E over a 12-month period were included. Among all the trauma patients with a chest CT (4204 patients), 160 were included in the final analysis. CWTs were measured at both sides and were compared in all subgroup of patients. RESULTS The average CWT for men on the 2nd ICS-MCL was 38mm and for women was 52mm; on the other hand, on the 5th ICS-MAL was 33mm for men and 38mm for women. On the 2nd ICS-MCL 17% of men and 48% of women; on the 5th ICS-MAL 13% of men and 33% of women would be inaccessible with a routine 5-cm catheter. Patients with trauma, subcutaneous emphysema and multiple rib fractures would have thicker CWT on the 2nd ICS-MCL. Patients with trauma, lung contusion, sternum fracture, subcutaneous emphysema and multiple rib fractures would have thicker CWT on the 5th ICS-MAL. CONCLUSIONS This study confirms that a 5.0-cm catheter would be unlikely to access the pleural space in at least 1/3 of female and 1/10 of male Turkish trauma patients, regardless of the puncture site. If NT is needed, the 5th ICS-MAL is a better option for a puncture site with thinner CWT.

Abstract
ABSTRACTMass casualty triage is the process of prioritizing multiple victims when resources are not sufficient to treat everyone immediately. No national guideline for mass casualty triage exists in the United States. The lack of a national guideline has resulted in variability in triage processes, tags, and nomenclature. This variability has the potential to inject confusion and miscommunication into the disaster incident, particularly when multiple jurisdictions are involved. The Model Uniform Core Criteria for Mass Casualty Triage were developed to be a national guideline for mass casualty triage to ensure interoperability and standardization when responding to a mass casualty incident. The Core Criteria consist of 4 categories: general considerations, global sorting, lifesaving interventions, and individual assessment of triage category. The criteria within each of these categories were developed by a workgroup of experts representing national stakeholder organizations who used the best available science and, when necessary, consensus opinion. This article describes how the Model Uniform Core Criteria for Mass Casualty Triage were developed.(Disaster Med Public Health Preparedness. 2011;5:129-137)

Abstract
Background We have previously described the utility of ThoraQuik, a device designed to be fit for purpose for aspirations of pneumothorax and pleural effusions. We evaluated the safety, efficacy and operator handling of the evolved prototype, ThoraQuik II, which has a lesser profile and a spring loaded Veres needle for added safety. Methods A prospective, observational clinical trial with ethics and MHRA approval was conducted in a single centre. Patients with diagnosed pneumothorax (including tension pneumothorax) and pleural effusion were consented and recruited. The ease of device introduction, penetration and ease of use were evaluated. Clinical and radiological improvements were the clinical endpoints and operator feedback was analysed. Results 20 procedures were performed on patients (mean age: 63.4 years (range: 30–90 years) with 75% male subjects) recruited between September 2008 and August 2009. Nine patients had pneumothorax (tension pneumothorax n=4) and 11 had pleural effusions. 19 patients completed the study with symptomatic and radiological resolution. One patient was withdrawn due to poor pain threshold disproportionate to the procedure. No complications were encountered. 68% had complete clinical and radiological resolution and 32% had partial resolution (these patients needed a definitive drain and hence were not aspirated to completion). The operator feedback in the study rated the device as very good or excellent in 90% patients. Conclusions Our study found the use of ThoraQuik II to be safe and easy in draining pneumothorax and pleural effusions. The changes to ThoraQuik II made it more user friendly.

Abstract
There is a need for model uniform core criteria for mass casualty triage because disasters frequently cross jurisdictional lines and involve responders from multiple agencies who may be using different triage tools. These criteria (Tables 1-4) reflect the available science, but it is acknowledged that there are significant research gaps. When no science was available, decisions were formed by expert consensus derived from the available triage systems. The intent is to ensure that providers at a mass-casualty incident use triage methodologies that incorporate these core principles in an effort to promote interoperability and standardization. At a minimum, each triage system must incorporate the criteria that are listed below. Mass casualty triage systems in use can be modified using these criteria to ensure interoperability. The criteria include general considerations, global sorting, lifesaving interventions, and assignment of triage categories. The criteria apply only to providers who are organizing multiple victims in a discrete geographic location or locations, regardless of the size of the incident. They are classified by whether they were derived through available direct scientific evidence, indirect scientific evidence, expert consensus, and/or are used in multiple existing triage systems. These criteria address only primary triage and do not consider secondary triage. For the purposes of this document the term triage refers to mass-casualty triage and provider refers to any person who assigns primary triage categories to victims of a mass-casualty incident.

Abstract
AbstractIntroduction:Tension pneumothorax is the second leading cause of preventable combat death. Although relatively simple, the management of tension pneumothorax is considered an advanced life support skill set. The purpose of this study was to assess the ability of non-medical law enforcement personnel to learn this skill set and to determine long-term knowledge and skill retention.Methods:After completing a pre-intervention questionnaire, a total of 22 tactical team operators completed a 90-minute-long training session in recognition and management of tension pneumothorax. Post-intervention testing was performed immediately post-training, and at one- and six-months post-training.Results:Initial training resulted in a significant increase in knowledge (pre: 1.3 ±1.35, max score 7; post: 6.8 ±0.62, p < 0.0001). Knowledge retention persisted at one- and six-months post-training, without significant decrement.Conclusions:Non-medical law enforcement personnel are capable of learning needle decompression, and retain this knowledge without significant deterioration for at least six months.

Evaluation of performance of two different chest tubes with either a sharp or a blunt tip for thoracostomy in 100 human cadavers. Scand J Trauma Resusc Emerg Med 2012; 20:10.

Abstract
BACKGROUND Emergent placement of a chest tube is a potentially life-saving procedure, but rate of misplacement and organ injury is up to 30%. In principle, chest tube insertion can be performed by using Trocar or Non-trocar techniques. If using trocar technique, two different chest tubes (equipped with sharp or blunt tip) are currently commercially available. This study was performed to detect any difference with respect to time until tube insertion, to success and to misplacement rate. METHODS Twenty emergency physicians performed five tube thoracostomies using both blunt and sharp tipped tube kits in 100 fresh human cadavers (100 thoracostomies with each kit). Time until tube insertion served as primary outcome. Complications and success rate were examined by pathological dissection and served as further outcomes parameters. RESULTS Difference in mean time until tube insertion (63 s vs. 59 s) was statistically not significant. In both groups, time for insertion decreased from the 1st to the 5th attempt and showed dependency on the cadaver's BMI and on the individual physician. Success rate differed between both groups (92% using blunt vs. 86% using sharp tipped kits) and injuries and misplacements occurred significantly more frequently using chest tubes with sharp tips (p = 0.04). CONCLUSION Data suggest that chest drain insertion with trocars is associated with a 6-14% operator-related complication rate. No difference in average time could be found. However, misplacements and organ injuries occurred more frequently using sharp tips. Consequently, if using a trocar technique, the use of blunt tipped kits is recommended.

Abstract
BACKGROUND Previous studies reported a high failure rate in relieving tension pneumothorax by needle thoracostomy, because the catheter was not sufficiently long to access the pleural space. The Advanced Trauma Life Support guideline recommends needle thoracostomy at the second intercostal space in the middle clavicular line using a 5.0-cm catheter, whereas the corresponding guideline in Japan does not mention a catheter length. It is necessary to measure the chest wall thickness (CWT) and determine the appropriate catheter length taking the differences of habitus in race and region into consideration. This study was designed to analyse CWT in Japanese trauma patients by computed tomography and to determine the percentage of patients whose pleural space would be accessible using a 5.0-cm catheter. PATIENTS AND METHODS We performed a retrospective review of chest computed tomography of 256 adult Japanese trauma patients who were admitted to the level 1 trauma centre of Tokai University Hospital in Kanagawa, Japan between January and July 2008. In 256 patients, the CWT at 512 sites (left and right sides) was measured by chest computed tomography at the second intercostal space in the middle clavicular line. The frequency of measurement sites <5.0 cm was calculated simultaneously. The samples were divided according to gender, side (left and right), abbreviated injury scale (<3, ≧3), arm position during examination (up/down), and the existence or non-existence of associated injuries (pneumothorax, subcutaneous emphysema, and fracture of the sternum and ribs); the CWT of each group was compared. RESULTS The mean CWT measured in 192 males and 64 females was 3.06±1.02 cm. The CWT values at 483 sites (94.3%) were less than 5.0 cm. The CWT of females was significantly greater than that of males (3.66 cm vs. 2.85 cm, p<0.0001), and patients with subcutaneous emphysema had greater CWTs than those without it (4.16 cm vs. 3.01 cm, p<0.0001). CONCLUSION The mean CWT at the second intercostal space in the middle clavicular line was 3.06 cm. It is likely that over 94% of Japanese trauma patients could be treated with a 5.0-cm catheter.

Abstract
BACKGROUND Tension pneumothorax (TPX) is an uncommon but life-threatening condition. It is important that this uncommon presentation, managed by needle decompression, is practised by paramedics using a range of educationally sound and realistic mannequins. The objective of this study is to identify if the chest wall thickness (CWT) of training mannequins used for chest decompression is an anatomically accurate representation of a human chest. METHODS This is a two-part study. A review of the literature was conducted to identify chest wall thickness in humans and measurement of chest wall thickness on two commonly used mannequins. The literature search was conducted using the Cochrane Central Register of Controlled Trials, MEDLINE, CINAHL, and EMBASE databases from their beginning until the end of May 2012. Key words included chest wall thickness, tension pneumothorax, pneumothorax, thoracostomy, needle thoracostomy, decompression, and needle test. Studies were included if they reported chest wall thickness. RESULTS For the literature review, 4 461 articles were located with 9 meeting the inclusion criteria. Chest wall thickness in adults varied between 1.3 cm and 9.3 cm at the area of the second intercostal space mid clavicular line. The Laerdal(®) manikin in the area of the second intercostal space mid clavicular line, right side of the chest was 1.1 cm thick with the left 1.5 cm. The MPL manikin in the same area or on the right side of the chest was 1.4 cm thick but on the left 1.0 cm. CONCLUSION Mannequin chests are not an accurate representation of the human chest when used for decompressing a tension pneumothorax and therefore may not provide a realistic experience.

Abstract
Severe chest trauma, blunt or penetrating, is responsible for up to 25% of traumatic deaths in North America. Respiratory compromise is the most frequent dramatic presentation in blunt trauma, while injuries to the heart and great vessels pose the greatest risk of immediate death following penetrating trauma. More than 80% of patients will be managed with interventions that can be performed in the emergency department. This article reviews the presentation, diagnosis, and management of the most important thoracic injuries. A structured approach to the acutely unstable patient is proposed to guide resuscitation decisions.

Abstract
BACKGROUND Needle thoracostomy is an emergent procedure designed to relieve tension pneumothorax. High failure rates because of the needle not penetrating into the thoracic cavity have been reported. Advanced Trauma Life Support guidelines recommend placement in the second intercostal space, midclavicular line using a 5-cm needle. The purpose of this study was to evaluate placement in the fifth intercostal space, midaxillary line, where tube thoracostomy is routinely performed. We hypothesized that this would result in a higher successful placement rate. METHODS Twenty randomly selected unpreserved adult cadavers were evaluated. A standard 14-gauge 5-cm needle was placed in both the fifth intercostal space at the midaxillary line and the traditional second intercostal space at the midclavicular line in both the right and left chest walls. The needles were secured and thoracotomy was then performed to assess penetration into the pleural cavity. The right and left sides were analyzed separately acting as their own controls for a total of 80 needles inserted into 20 cadavers. The thickness of the chest wall at the site of penetration was then measured for each entry position. RESULTS A total of 14 male and 6 female cadavers were studied. Overall, 100% (40 of 40) of needles placed in the fifth intercostal space and 57.5% (23 of 40) of the needles placed in the second intercostal space entered the chest cavity (p < 0.001); right chest: 100% versus 60.0% (p = 0.003) and left chest: 100% versus 55.0% (p = 0.001). Overall, the thickness of the chest wall was 3.5 cm ± 0.9 cm at the fifth intercostal space and 4.5 cm ± 1.1 cm at the second intercostal space (p < 0.001). Both right and left chest wall thicknesses were similar (right, 3.6 cm ± 1.0 cm vs. 4.5 cm ± 1.1 cm, p = 0.007; left, 3.5 ± 0.9 cm vs. 4.4 cm ± 1.1 cm, p = 0.008). CONCLUSIONS In a cadaveric model, needle thoracostomy was successfully placed in 100% of attempts at the fifth intercostal space but in only 58% at the traditional second intercostal position. On average, the chest wall was 1 cm thinner at this position and may improve successful needle placement. Live patient validation of these results is warranted.
