Abstract
BACKGROUND Needle thoracostomy is a potentially life-saving intervention for tension pneumothorax but may be overused, potentially leading to unnecessary morbidity. OBJECTIVE To review prehospital needle thoracostomy indications, effectiveness, and adverse outcomes. METHODS A retrospective cohort study was conducted based on registry data for a United States Midwestern Level I trauma center for a 7.5-year period (January 2015 to May 2022). Included were patients who received prehospital needle thoracostomy and trauma activation before hospital arrival. The primary outcomes were correct indications and improvement in vital signs. Secondary outcomes were the need for chest tubes, correct needle placement, complications, and survival. RESULTS A total of n = 67 patients were reviewed, of which n = 63 (94%) received a prehospital thoracostomy. Of the 63 prehospital thoracostomies, 54 (86%) survived to arrival. Of these 54, 44 (n = 81%) had documented reduced/absent breath sounds, 15 (28%) hypotension, and 19 (35%) with difficulty breathing/ventilating. Only four patients met all three prehospital trauma life support criteria: hypotension, difficulty ventilating, and absent breath sounds. There were no significant changes in prehospital vitals before and after receiving needle thoracostomy. In patients receiving imaging (n = 54), there was evidence of 15 (28%) lung lacerations, 6 (11%) of which had a pneumothorax and 3 (5%) near misses of important structures. Review of needle catheters visible on computer tomography imaging found 11 outside the chest and 1 in the abdominal cavity. CONCLUSION The study presents evidence of potential needle thoracostomy overuse and morbidity. Adherence to specific guidelines for needle decompression is needed.

Can Respir J 2023; 2023:2602988. [PMID: 37181158 PMCID: PMC10174999 DOI: 10.1155/2023/2602988] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2022] [Revised: 02/03/2023] [Accepted: 04/15/2023] [Indexed: 05/16/2023] Open
Abstract
Background There are very few professional recommendations or guidelines on the needle thoracentesis decompression (NTD) for the tension pneumothorax in the elderly. This study aimed to investigate the safety and risk factors of tension pneumothorax NTD in patients over 75 years old based on CT evaluation of the chest wall thickness (CWT). Methods The retrospective study was conducted among 136 in-patients over 75 years old. The CWT and closest depth to vital structure of the second intercostal space at the midclavicular line (second ICS-MCL) and the fifth intercostal space at the midaxillary line (fifth ICS-MAL) were compared as well as the expected failure rates and the incidence of severe complications of different needles. We also analyzed the influence of age, sex, presence or absence of chronic obstructive pulmonary disease (COPD), and body mass index (BMI) on CWT. Results The CWT of the second ICS-MCL was smaller than the fifth ICS-MAL both on the left and the right side (P < 0.05). The success rate associated with a 7 cm needle was significantly higher than a 5 cm needle (P < 0.05), and the incidence of severe complications with a 7 cm needle was significantly less than an 8 cm needle (P < 0.05). The CWT of the second ICS-MCL was significantly correlated with age, sex, presence or absence of COPD, and BMI (P < 0.05), whereas the CWT of the fifth ICS-MAL was significantly correlated with sex and BMI (P < 0.05). Conclusion The second ICS-MCL was recommended as the primary thoracentesis site and a 7 cm needle was advised as preferred needle length for the older patients. Factors such as age, sex, presence or absence of COPD, and BMI should be considered when choosing the appropriate needle length.

Abstract
Importance Prehospital needle decompression (PHND) is a rare but potentially life-saving procedure. Prior studies on chest decompression in trauma patients have been small, limited to single institutions or emergency medical services (EMS) agencies, and lacked appropriate comparator groups, making the effectiveness of this intervention uncertain. Objective To determine the association of PHND with early mortality in patients requiring emergent chest decompression. Design, Setting, and Participants This was a retrospective cohort study conducted from January 1, 2000, to March 18, 2020, using the Pennsylvania Trauma Outcomes Study database. Patients older than 15 years who were transported from the scene of injury were included in the analysis. Data were analyzed between April 28, 2021, and September 18, 2021. Exposures Patients without PHND but undergoing tube thoracostomy within 15 minutes of arrival at the trauma center were the comparison group that may have benefited from PHND. Main Outcomes and Measures Mixed-effect logistic regression was used to determine the variability in PHND between patient and EMS agency factors, as well as the association between risk-adjusted 24-hour mortality and PHND, accounting for clustering by center and year. Propensity score matching, instrumental variable analysis using EMS agency-level PHND proportion, and several sensitivity analyses were performed to address potential bias. Results A total of 8469 patients were included in this study; 1337 patients (11%) had PHND (median [IQR] age, 37 [25-52] years; 1096 male patients [82.0%]), and 7132 patients (84.2%) had emergent tube thoracostomy (median [IQR] age, 32 [23-48] years; 6083 male patients [85.3%]). PHND rates were stable over the study period between 0.2% and 0.5%. Patient factors accounted for 43% of the variation in PHND rates, whereas EMS agency accounted for 57% of the variation. PHND was associated with a 25% decrease in odds of 24-hour mortality (odds ratio [OR], 0.75; 95% CI, 0.61-0.94; P = .01). Similar results were found in patients who survived their ED stay (OR, 0.68; 95% CI, 0.52-0.89; P < .01), excluding severe traumatic brain injury (OR, 0.65; 95% CI, 0.45-0.95; P = .03), and restricted to patients with severe chest injury (OR, 0.72; 95% CI, 0.55-0.93; P = .01). PHND was also associated with lower odds of 24-hour mortality after propensity matching (OR, 0.79; 95% CI, 0.62-0.98; P = .04) when restricting matches to the same EMS agency (OR, 0.74; 95% CI, 0.56-0.99; P = .04) and in instrumental variable probit regression (coefficient, -0.60; 95% CI, -1.04 to -0.16; P < .01). Conclusions and Relevance In this cohort study, PHND was associated with lower 24-hour mortality compared with emergent trauma center chest tube placement in trauma patients. Although performed rarely, PHND can be a life-saving intervention and should be reinforced in EMS education for appropriately selected trauma patients.

Prehospital care for traumatic cardiac arrest in the US: A cross-sectional analysis and call for a national guideline. Resuscitation 2022; 179:97-104. [PMID: 35970396 DOI: 10.1016/j.resuscitation.2022.08.005] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/04/2022] [Revised: 08/01/2022] [Accepted: 08/07/2022] [Indexed: 11/21/2022]
Abstract
AIM We describe emergency medical services (EMS) protocols and prehospital practice patterns related to traumatic cardiac arrest (TCA) management in the U.S. METHODS We examined EMS management of TCA by 1) assessing variability in recommended treatments in state EMS protocols for TCA and 2) analyzing EMS care using a nationwide sample of EMS activations. We included EMS activations involving TCA in adult (≥18 years) patients where resuscitation was attempted by EMS. Descriptive statistics for recommended and actual treatments were calculated and compared between blunt and penetrating trauma using χ2 and independent 2-group Mann-Whitney U tests. RESULTS There were 35 state EMS protocols publicly available for review, of which 16 (45.7%) had a specific TCA protocol and 17 (48.5%) had a specific termination of resuscitation protocol for TCA. Recommended treatments varied. We then analyzed 9,565 EMS activations involving TCA (79.1% blunt, 20.9% penetrating). Most activations (93%) were managed by advanced life support. Return of spontaneous circulation was achieved in 25.5% of activations, and resuscitation was terminated by EMS in 26.4% of activations. Median prehospital scene time was 16.4 minutes; scene time was shorter for penetrating mechanisms than blunt (12.0 vs 17.0 min, p < 0.001). Endotracheal intubation was performed in 32.0% of activations, vascular access obtained in 66.6%, crystalloid fluids administered in 28.8%, and adrenaline administered in 60.1%. CONCLUSION Actual and recommended approaches to EMS treatment of TCA vary nationally. These variations in protocols and treatments highlight the need for a standardized approach to prehospital management of TCA in the U.S.

Abstract
OBJECTIVES The Tactical Combat Casualty Care (TCCC) guidelines detail resuscitation practices in prehospital and austere environments. We sought to review the content and quality of the current TCCC and civilian prehospital literature and characterize knowledge gaps to offer recommendations for future research. METHODS MEDLINE, EMBASE, CINAHL, and Cochrane Central Register of Controlled Trials were searched for studies assessing intervention techniques and devices used in civilian and military prehospital settings that could be applied to TCCC guidelines. Screening and data extraction were performed according to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Quality appraisal was conducted using appropriate tools. RESULTS Ninety-two percent (n=57) of studies were observational. Most randomized trials had low risk of bias, whereas observational studies had higher risk of bias. Interventions of massive hemorrhage control (n=17) were wound dressings and tourniquets, suggesting effective hemodynamic control. Airway management interventions (n=7) had high success rates with improved outcomes. Interventions of respiratory management (n=12) reported low success with needle decompression. Studies assessing circulation (n=18) had higher quality of evidence and suggested improved outcomes with component hemostatic therapy. Hypothermia prevention interventions (n=2) were generally effective. Other studies identified assessed the use of extended focused assessment with sonography in trauma (n=3) and mixed interventions (n=2). CONCLUSIONS The evidence was largely non-randomized with heterogeneous populations, interventions, and outcomes, precluding robust conclusions in most subjects addressed in the review. Knowledge gaps identified included the use of blood products and concentrate of clotting factors in the prehospital setting. LEVEL OF EVIDENCE Systematic review, level III.

Abstract
BACKGROUND Tension pneumothorax (TPT) is a frequent life-threat following thoracic injury. Time-critical decompression of the pleural cavity improves survival. However, whilst paramedics utilise needle thoracostomy (NT) and/or finger thoracostomy (FT) in the prehospital setting, the superiority of one technique over the other remains unknown. AIM To determine and compare procedural success, complications and mortality between NT and FT for treatment of a suspected TPT when performed by paramedics. METHODS We searched four databases (Ovid Medline, PubMed, CINAHL and Embase) from their commencement until 25th August 2020. Studies were included if they analysed patients suffering from a suspected TPT who were treated in the prehospital setting with a NT or FT by paramedics (or local equivalent nonphysicians). RESULTS The search yielded 293 articles after duplicates were removed of which 19 were included for final analysis. Seventeen studies were retrospective (8 cohort; 7 case series; 2 case control) and two were prospective cohort studies. Only one study was comparative, and none were randomised controlled trials. Most studies were conducted in the USA (n=13) and the remaining in Australia (n=4), Switzerland (n=1) and Canada (n=1). Mortality ranged from 12.5% to 79% for NT and 64.7% to 92.9% for FT patients. A higher proportion of complications were reported among patients managed with NT (13.7%) compared to FT (4.8%). We extracted three common themes from the papers of what constituted as a successful pleural decompression; vital signs improvement, successful pleural cavity access and absence of TPT at hospital arrival. CONCLUSION Evidence surrounding prehospital pleural decompression of a TPT by paramedics is limited. Available literature suggests that both FT and NT are safe for pleural decompression, however both procedures have associated complications. Additional high-quality evidence and comparative studies investigating the outcomes of interest is necessary to determine if and which procedure is superior in the prehospital setting.

Abstract
Background Traumatic tension pneumothoraces (TPT) are among the most serious causes of death in traumatic injuries, requiring immediate treatment with a needle thoracostomy (NT). Improperly placed NT insertion into the pleural cavity may fail to treat a life-threatening TPT. This study aimed to assess the accuracy of prehospital NT placements by paramedics in adult trauma patients. Methods A retrospective chart review was performed on 84 consecutive trauma patients who had received NT by prehospital personnel. The primary outcome was the accuracy of NT placement by prehospital personnel. Comparisons of various variables were conducted between those who survived and those who died, and proper versus improper needle insertion separately. Results Proper NT placement into the pleural cavity was noted in 27.4% of adult trauma patients. In addition, more than 19% of the procedures performed by the prehospital providers appeared to have not been medically indicated. Discussion Long-term strategies may be needed to improve the capabilities and performance of prehospital providers' capabilities in this delicate life-saving procedure. Level of evidence IV.

Abstract
BACKGROUND Prehospital procedures (PHP) by emergency medical services (EMS) are performed regularly in penetrating trauma patients despite previous studies demonstrating no benefit. We sought to examine the influence of PHPs on outcomes in penetrating trauma patients in urban locations where transport to trauma center is not prolonged. We hypothesized that patients without PHPs would have better outcomes than those undergoing PHP. METHODS This was an Eastern Association for the Surgery of Trauma-sponsored, multicenter, prospective, observational trial of adults (18+ years) with penetrating trauma to the torso and/or proximal extremity presenting at 25 urban trauma centers. The impact of PHPs and transport mechanism on in-hospital mortality were examined. RESULTS Of 2,284 patients included, 1,386 (60.7%) underwent PHP. The patients were primarily Black (n = 1,527, 66.9%) males (n = 1,986, 87.5%) injured by gunshot wound (n = 1,510, 66.0%) with 34.1% (n = 726) having New Injury Severity Score of ≥16. A total of 1,427 patients (62.5%) were transported by Advanced Life Support EMS, 17.2% (n = 392) by private vehicle, 13.7% (n = 312) by police, and 6.7% (n = 153) by Basic Life Support EMS. Of the PHP patients, 69.1% received PHP on scene, 59.9% received PHP in route, and 29.0% received PHP both on scene and in route. Initial scene vitals differed between groups, but initial emergency department vitals did not. Receipt of ≥1 PHP increased mortality odds (odds ratio [OR], 1.36; 95% confidence interval [CI], 1.01-1.83; p = 0.04). Logistic regression showed increased mortality with each PHP, whether on scene or during transport. Subset analysis of specific PHP revealed that intubation (OR, 10.76; 95% CI, 4.02-28.78; p < 0.001), C-spine immobilization (OR, 5.80; 95% CI, 1.85-18.26; p < 0.01), and pleural decompression (OR, 3.70; 95% CI, 1.33-10.28; p = 0.01) had the highest odds of mortality after adjusting for multiple variables. CONCLUSION Prehospital procedures in penetrating trauma patients impart no survival advantage and may be harmful in urban settings, even when performed during transport. Therefore, PHP should be forgone in lieu of immediate transport to improve patient outcomes. LEVEL OF EVIDENCE Prognostic, level III.

Abstract
Objective: Needle thoracostomy (NT) can be a life-saving procedure when used to treat tension pneumothorax. However, there is some question regarding the efficacy of NT in the prehospital setting. Failure to treat tension pneumothorax in a helicopter emergency medical service (HEMS) setting may prove especially deleterious to the patient due to gas expansion with increasing altitude. This study's objective was to identify the characteristics of patients treated with NT in a Canadian HEMS setting and the factors that may influence outcomes following NT use.Methods: This was a retrospective chart review of prehospital records from a Canadian HEMS service. Patients aged 18 years and older who underwent at least one NT attempt using a 14-gauge 8.3 cm needle from 2012 to 2018 were identified. Charts were reviewed to collect demographic data, NT procedural characteristics, vital signs, and clinical response metrics. Descriptive statistics were used to characterize the study sample and overall event characteristics. Binary logistic regression was performed to identify variables associated with a clinical response to the initial NT treatment.Results: 163 patients (1.3%) of 12,407 patients attended received NT. A positive clinical response to NT was recorded in 37% (n = 77) of the total events (n = 208), the most common of which was an improvement in blood pressure (BP) (18.8%, n = 39). Initial NT was associated with a low likelihood of clinical improvement in patients presenting with blunt trauma (OR = 0.18; p = .021; 95% CI [.04, .77]), CPR prior to NT (OR = 0.14; p = .02; 95% CI [.03, .73]), or in those who received bilateral NT treatment (OR = 0.13; p < .01; 95% CI [.05, .37]). A pretreatment BP < 90 mmHg was predictive of a positive clinical response to initial NT (OR = 3.33; p = .04; 95% CI [1.09, 10.20]).Conclusions: Only a small portion of patients in the setting of a Canadian HEMS service were treated with NT. Patients most likely to receive NT were males who had suffered blunt trauma. NT may have questionable benefit for patients presenting with blunt trauma, in cardiac arrest, or requiring bilateral NT.

Abstract
BACKGROUND Cricothyrotomy and chest needle decompression (NDC) have a high failure and complication rate. This article sought to determine whether paramedics can correctly identify the anatomical landmarks for cricothyrotomy and chest NDC. METHODS A prospective study using human models was performed. Paramedics were partnered and requested to identify the location for cricothyrotomy and chest NDC (both mid-clavicular and anterior axillary sites) on each other. A board-certified or board-eligible emergency medicine physician timed the process and confirmed location accuracy. All data were collected de-identified. Descriptive analysis was performed on continuous data; chi-square was used for categorical data. RESULTS A total of 69 participants were recruited, with one excluded for incomplete data. The paramedics had a range of six to 38 (median 14) years of experience. There were 28 medical training officers (MTOs) and 41 field paramedics. Cricothyroidotomy location was correctly identified in 56 of 68 participants with a time to identification range of 2.0 to 38.2 (median 8.6) seconds. Chest NDC (mid-clavicular) location was correctly identified in 54 of 68 participants with a time to identification range of 3.4 to 25.0 (median 9.5) seconds. Chest NDC (anterior axillary) location was correctly identified in 43 of 68 participants with a time to identification range of 1.9 to 37.9 (median 9.6) seconds. Chi-square (2-tail) showed no difference between MTO and field paramedic in cricothyroidotomy site (P = .62), mid-clavicular chest NDC site (P = .21), or anterior axillary chest NDC site (P = .11). There was no difference in time to identification for any procedure between MTO and field paramedic. CONCLUSION Both MTOs and field paramedics were quick in identifying correct placement of cricothyroidotomy and chest NDC location sites. While time to identification was clinically acceptable, there was also a significant proportion that did not identify the correct landmarks.

Risk Values of Weight and Body Mass Index for Chest Wall Thickness in Patients Requiring Needle Thoracostomy Decompression. Emerg Med Int 2020; 2020:2070157. [PMID: 33178460 PMCID: PMC7609141 DOI: 10.1155/2020/2070157] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/09/2019] [Revised: 02/28/2020] [Accepted: 03/17/2020] [Indexed: 11/17/2022] Open
Abstract
Introduction Emergency decompression is needed in patients with tension pneumothorax, a life-threatening condition. The catheter-based needle thoracostomy was suggested using a 5 cm catheter inserted into the 2nd intercostal space (ICS) and 5th ICS according to the ninth and tenth editions of Advanced Trauma Life Support, respectively. A catheter of suitable length may not be available immediately or the muscle structure of the chest wall may be modified in pneumothorax. Furthermore, alternative sites for needle thoracostomy and reference values of chest wall thickness (CWT) should be explored and warranted. Method CT scan data and medical data of 650 eligible patients from October 2016 to December 2016 were reviewed. CWT values at four ICSs as well as four variables, namely, age, weight, height, and body mass index (BMI) for both men and women were compared using a nonparametric method, namely, the Wilcoxon signed-rank test. The associations between CWT and the four variables were assessed using the Pearson correlation coefficient. The overall performance of BMI, weight, and height in predicting CWT > 5 cm was evaluated using the receiver-operating characteristic (ROC) curve. Finally, the prediction models were built by using the bootstrap method. Results Four variables, namely, age, height, weight, and BMI, were compared between the men and women groups. All four variables differed significantly between the two groups, and CWTs at all ICSs, except for the 3rd ICS, differed significantly between the two groups. Among the women, the area under the ROC curve (AUROC) of BMI for predicting CWT > 5 cm at 2nd ICS was larger than the AUROC of weight and height. Among the men, the AUROC of weight for predicting CWT > 5 cm at 2nd ICS was larger than that of BMI and height. The reference value tables were provided for five proposed models for women and men, respectively. Under emergencies, the variable, BMI, or even weight itself, could be used for predicting a failure performance of the needle decompression. For women, CWT at 5th ICS was predicted over 5 cm at BMI over 25.9 kg/m2 or weight over 103.1 kg. For men, CWT at 5th ICS was predicted over 5 cm at BMI over 25.5 kg/m2 or weight over 157.4 kg. Conclusion Needle thoracostomy is the preferred first technique for many emergency providers for decompression. Therefore, a reference table for safe needle thoracostomy decompression at four usual sites, namely, 2nd ICS, 3rd CIS, 4th ICS, and 5th ICS, was recommended, which will enable paramedics and emergency specialists to rapidly determine CWT at the appropriate ICSs during emergencies.

Comparison of 10- versus 14-gauge angiocatheter for treatment of tension pneumothorax and tension-induced pulseless electrical activity with hemorrhagic shock: Bigger is still better. J Trauma Acute Care Surg 2020; 89:S132-S136.

Abstract
BACKGROUND Little is known regarding the effect of hemorrhagic shock on the diagnosis and treatment of tension pneumothorax (tPTX). Recently, the Tactical Combat Casualty Care guidelines included the 10-gauge angiocatheter (10-g AC) as an acceptable alternative to the 14-g AC. This study sought to compare these two devices for decompression of tPTX and rescue from tension-induced pulseless electric activity (tPEA) in the setting of a concomitant 30% estimated blood volume hemorrhage. METHODS Following a controlled hemorrhage, carbon dioxide was insufflated into the chest to induce either tPTX or tPEA. Tension pneumothorax was defined as a reduction in cardiac output by 50%, and tPEA was defined as a loss of arterial waveform with mean arterial pressure less than 20 mm Hg. The affected hemithorax was decompressed using a randomized 14-g AC or 10-g AC while a persistent air leak was maintained after decompression. Successful rescue from tPTX was defined as 80% recovery of baseline systolic blood pressure, while successful return of spontaneous circulation following tPEA was defined as a mean arterial pressure greater than 20 mm Hg. Primary outcome was success of device. RESULTS Eighty tPTX and 50 tPEA events were conducted in 38 adult Yorkshire swine. There were no significant differences in the baseline characteristics between animals or devices. In the tPTX model, the 10-g AC successfully rescued 90% of events, while 14-g AC rescued 80% of events (p = 0.350). In the tPEA model, the 10-g AC rescued 87% of events while the 14 AC rescued only 48% of events (p = 0.006). CONCLUSION The 10-g AC was vastly superior to the 14-g AC for return of spontaneous circulation following tPEA in the setting of 30% hemorrhage. These findings further support the importance of larger caliber devices that facilitate rapid recovery from tPTX, particularly in the setting of polytrauma. LEVEL OF EVIDENCE Therapeutic, level II.

Abstract
BACKGROUND Cardiopulmonary resuscitation (CPR) in special circumstances includes the emergency intervention for special causes, special environments, and special patients. Special causes cover the potential reversible causes of cardiac arrest that must be identified or excluded during any resuscitation act. The special environments section includes recommendations for the treatment of cardiac arrest occurring in specific locations: cardiac surgery, catheterization laboratory, dialysis unit, dental surgery, commercial airplanes or air ambulances, playing field, difficult environment (eg, drowning, high altitude, avalanche, and electrical injuries) or mass casualty incident. CPR for special patients gives guidance for the patients with severe comorbidities (asthma, heart failure with ventricular assist devices, neurological disease, and obesity) and pregnant women or older people. AREAS OF UNCERTAINTY There are no generally worldwide accepted resuscitation guidelines for special circumstance, and there are still few studies investigating the safety and outcome of cardiac arrest in special circumstances. Applying standard advanced life support (ALS) guidelines in this situation is not enough to obtain better results from CPR, for example, cardiac arrest caused by electrolyte abnormalities require also the treatment of that electrolyte disturbance, not only standard CPR, or in the case of severe hypothermia, when standard ALS approach is not recommended until a temperature threshold is reached after warming measures. Data sources for this article are scientific articles describing retrospective studies conducted in CPR performed in special circumstances, experts' consensus, and related published opinion of experts in CPR. THERAPEUTIC ADVANCES The newest advance in therapeutics applied to resuscitation field for these particular situations is the use of extracorporeal life support/extracorporeal membrane oxygenation devices during CPR. CONCLUSIONS In special circumstances, ALS guidelines require modification and special attention for causes, environment, and patient particularities, with specific therapeutic intervention concomitant with standard ALS.

Abstract
BACKGROUND Tube thoracostomy has long been the standard of care for treatment of tension pneumothorax in the hospital setting yet is uncommon in prehospital care apart from helicopter emergency medical services. OBJECTIVE We aimed to evaluate the performance of simple thoracostomy (ST) for patients with traumatic cardiac arrest and suspected tension pneumothorax. METHODS We conducted a retrospective case series of consecutive patients with traumatic cardiac arrest where simple thoracostomy was used during the resuscitation effort. Data were abstracted from our Zoll emergency medical record (Zoll Medical Corp., Chelmsford, MA) for patients who received the procedure between June 1, 2013 and July 1, 2017. We collected general descriptive characteristics, procedural success, presence of air or blood, and outcomes for each patient. RESULTS During the study period we performed ST on 57 patients. The mean age was 41 years old (range 15-81 years old) and 83% were male. Indications included 40 of 57 (70%) blunt trauma and 17 of 57 (30%) penetrating trauma. The presenting rhythm was pulseless electrical activity 65%, asystole 26%, ventricular tachycardia/fibrillation 4%, and nonrecorded 5%. Eighteen of 57 (32%) had air return, 14 of 57 (25%) return of spontaneous circulation, with 6 of 57 (11%) surviving to 24 h and 4 of 57 (7%) discharged from the hospital neurologically intact. Of the survivors, all were blunt trauma mechanism with initial rhythms of pulseless electrical activity. There were no reported medic injuries. CONCLUSIONS Our data show that properly trained paramedics in ground-based emergency medical services were able to safely and effectively perform ST in patients with traumatic cardiac arrest. We found a significant (32%) presence of pneumothorax in our sample, which supports previously reported high rates in this patient population.

Abstract
AbstractBackgroundNeedle thoracostomy (NT) is a common prehospital intervention for patients in extremis or cardiac arrest due to trauma. The purpose of this study is to compare outcomes, efficacy, and complications after a change in policy related to NT in a four-county Emergency Medical Services (EMS) system with a catchment area of greater than 1.6 million people.MethodsThis is a before and after observational study of all patients who had NT performed in the Central California (USA) EMS system. The before, anterior midclavicular line (MCL) group consisted of all patients who underwent NT from May 7, 2007 through February 28, 2013. The after, midaxillary line (MAL) axillary group consisted of all patients who underwent NT from March 1, 2013 through January 30, 2016, after policy revisions changed the timing, needle size, and placement location for NT. All prehospital and hospital records where NT was performed were queried for demographics, mechanism of injury, initial status and post-NT clinical change, reported complications, and final outcome. The trauma registry was accessed to obtain Injury Severity Scores (ISS). Information was manually abstracted by study investigators and examined utilizing univariate and multivariate analyses.ResultsThree-hundred and five trauma patients treated with NT were included in this study, of which, 169 patients (the MCL group) were treated with a 14-guage intravenous (IV) catheter at least 5.0-cm long at the second intercostal space (ICS), MCL after being placed in the ambulance; and 136 patients (the MAL group) were treated with a 10-guage IV catheter at least 9.5-cm long at the fifth ICS, MAL on scene. The mean ISS was lower in the MAL cohort (64.5 versus 69.2; P=.007). The mortality rate was 79% in both groups. The multivariate model with regard to survival supported that a lower ISS (P<.001) and reported clinical change after NT (P=.003) were significant indicators of survival. No complications from NT were reported.ConclusionsChanging the timing, length of needle, and location of placement did not change mortality in patients requiring NT. Needle thoracostomy was used more frequently after the change in policy, and the MAL cohort was less injured. No increase in reported complications was noted.WeichenthalLA, OwenS, StrohG, RamosJ.

Abstract
BACKGROUND Decompression of tension physiology may be lifesaving, but significant doubts remain regarding ideal needle thoracostomy (NT) catheter length in the treatment of tension physiology. We aimed to demonstrate increased clinical effectiveness of longer NT angiocatheter (8 cm) compared with current Advanced Trauma Life Support recommendations of 5-cm NT length. METHODS This is a retrospective review of all adult trauma patients from 2003 to 2013 (age > 15 years) transported to a Level I trauma center. Patients underwent NT at the second intercostal space midclavicular line, either at the scene of injury, during transport (prehospital), or during initial hospital trauma resuscitation. Before March 2011, both prehospital and hospital trauma team NT equipment routinely had a 5-cm angiocatheter available. After March 2011, prehospital providers were provided an 8-cm angiocatheter. Effectiveness was defined as documented clinical improvement in respiratory, cardiovascular, or general clinical condition. RESULTS There were 91 NTs performed on 70 patients (21 bilateral placements) either in the field (prehospital, n = 41) or as part of resuscitation in the hospital (hospital, n = 29). Effectiveness of NT was 48% until March 2011 (n = 24). NT effectiveness was significantly higher in the prehospital setting than in the hospital (68.3% success rate vs. 20.7%, p < 0.01). Patients who underwent NT using 8 cm compared with 5 cm were significantly more effective (83% vs. 41%, respectively, p = 0.01). No complications of NT were identified in either group. CONCLUSION Eight-centimeter angiocatheters are more effective at chest decompression compared with currently recommended 5 cm at the second intercostal space midclavicular line.

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.

Abstract
Pre-hospital care requires a broad skillset. One of the most challenging aspects of pre-hospital care is performing surgical procedures. The indications and evidence for performing pre-hospital surgical airway, thoracostomy, thoracotomy, caesarean section and amputation are discussed. Where evidence for the procedure is lacking from pre-hospital care, evidence from in-hospital experience is sought.

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.

Decreased mortality after prehospital interventions in severely injured trauma patients. J Trauma Acute Care Surg 2015.

Abstract
BACKGROUND We test the hypothesis that prehospital interventions (PHIs) performed by skilled emergency medical service providers during ground or air transport adversely affect outcome in severely injured trauma patients. METHODS Consecutive trauma activations (March 2012 to June 2013) transported from the scene by air or ground emergency medical service providers were reviewed. PHI was defined as intubation, needle decompression, tourniquet, cricothyroidotomy, or advanced cardiac life support. RESULTS In 3,733 consecutive trauma activations (71% blunt, 25% penetrating, 4% burns), age was 39 years, 74% were male, Injury Severity Score (ISS) was 5, and Glasgow Coma Score (GCS) was 15, with 32% traumatic brain injury (TBI) and 7% overall mortality. Those who received PHI (n = 130, 3.5% of the trauma activations) were more severely injured: ISS (26 vs. 5), GCS (3 vs. 15), TBI (57% vs. 31%), Revised Trauma Score (RTS, 5.45 vs. 7.84), Trauma and Injury Severity Score (TRISS, 1.32 vs. 4.89), and mortality (56% vs. 5%) were different (all p < 0.05) than those who received no PHI. Air crews transported 22% of the patients; more had TBI, blunt injury, high ISS, and long prehospital times (all p < 0.05), but mortality was similar to those transported by ground. In the most severely injured patients with signs of life who received a PHI, the ISS, prehospital times, and proportions of TBI, blunt trauma, and air transport were similar, but mortality was significantly lower (43% vs. 23%, p= 0.021). CONCLUSION In our urban trauma system, PHIs are associated with a lower incidence of mortality in severely injured trauma patients and do not delay transport to definitive care. LEVEL OF EVIDENCE Prognostic/epidemiologic study, level III; therapeutic study, level IV.

Abstract
BACKGROUND Historic improvements in operative trauma care have been driven by war. It is unknown whether recent battlefield innovations stemming from conflicts in Iraq/Afghanistan will follow a similar trend. The objective of this study was to survey trauma medical directors (TMDs) at level 1-3 trauma centers across the United States and gauge the extent to which battlefield innovations have shaped civilian practice in 4 key domains of trauma care. METHODS Domains were determined by the use of a modified Delphi method based on multiple consultations with an expert physician/surgeon panel: (1) damage control resuscitation (DCR), (2) tourniquet use, (3) use of hemostatic agents, and (4) prehospital interventions, including intraosseous catheter access and needle thoracostomy. A corresponding 47-item electronic anonymous survey was developed/pilot tested before dissemination to all identifiable TMD at level 1-3 trauma centers across the US. RESULTS A total of 245 TMDs, representing nearly 40% of trauma centers in the United States, completed and returned the survey. More than half (n = 127; 51.8%) were verified by the American College of Surgeons. TMDs reported high civilian use of DCR: 95.1% of trauma centers had implemented massive transfusion protocols and the majority (67.7%) tended toward 1:1:1 packed red blood cell/fresh-frozen plasma/platelets ratios. For the other 3, mixed adoption corresponded to expressed concerns regarding the extent of concomitant civilian research to support military research and experience. In centers in which policies reflecting battlefield innovations were in use, previous military experience frequently was acknowledged. CONCLUSION This national survey of TMDs suggests that military data supporting DCR has altered civilian practice. Perceived relevance in other domains was less clear. Civilian academic efforts are needed to further research and enhance understandings that foster improved trauma surgeon awareness of military-to-civilian translation.

Needle Thoracostomy for Patients with Prolonged Transport Times: A Case-control Study. Prehosp Disaster Med 2015; 30:397-401.

Abstract
UNLABELLED Introduction The use of prehospital needle thoracostomy (NT) is controversial. Some studies support its use; however, concerns exist regarding misplacement, inappropriate patient selection, and iatrogenic injury. Even less is known about its efficacy in situations where there is a delay to definitive care. Hypothesis/Aim To determine any differences in survival of patients who underwent NT in the setting of prolonged versus short transport times, and to describe differences in mechanisms and complications between the two groups. METHODS This was a retrospective, matched, case-control study of trauma patients in a four county Emergency Medical Service (EMS) system from April 1, 2007 through April 1, 2013. This system serves an urban, rural, and wilderness catchment area. A prehospital database was queried for all patients in whom NT was performed, identifying 182 patients. When these calls were limited to those with prolonged transport times, the search was narrowed to 32 cases. A matched control group, based on age and gender, with short transport times was then created as a comparison. Data collected from prehospital and hospital records included: demographics; mechanism of injury; call status; response to NT; and final outcome. Univariate and multivariate analyses were conducted, as appropriate, to assess the primary outcome of survival and to further elucidate the descriptive data. RESULTS There was no difference in survival between the case and control groups, either when evaluated with univariate (34% vs 25%; P=.41) or multivariate (odds ratio=0.99; 95% CI, 0.96-1.02; P=.57) analyses. Blunt trauma was the most common mechanism in both groups, but penetrating trauma was more common in the control group (30% vs 9%; P=.003). Patients in the control group were also more likely to have no vital signs on initial assessment (62% vs 31%; P=.003). More patients in the case group were described as having clinical improvement after NT (34% vs 19%; P=.03). No complications of NT were reported in either group. CONCLUSIONS There was no significant difference in survival between patients with prolonged versus short transport times who underwent NT. Patients with prolonged transport times were more likely to have sustained blunt trauma, have vital signs on EMS arrival, and to have clinical improvement after NT.

Abstract
BackgroundThe role of ambulance services has changed dramatically over the last few decades with the introduction of paramedics able to provide life-saving interventions, thanks to sophisticated equipment and treatments available. The number of 999 calls continues to increase, with adverse events theoretically possible with each one. Most patient safety research is based on hospital data, but little is known concerning patient safety when using ambulance services, when things can be very different. There is an urgent need to characterise the evidence base for patient safety in NHS ambulance services.ObjectiveTo identify and map available evidence relating to patient safety when using ambulance services.DesignMixed-methods design including systematic review and review of ambulance service documentation, with areas for future research prioritised using a Delphi process.Setting and participantsAmbulance services, their staff and service users in UK.Data sourcesA wide range of data sources were explored. Multiple databases, reference lists from key papers and citations, Google and the NHS Confederation website were searched, and experts contacted to ensure that new data were included in the review. The databases MEDLINE, EMBASE, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Web of Science, Science Direct, Emerald, Education Resources Information Center (ERIC), Applied Social Sciences Index and Abstracts, Social Services Abstracts, Sociological Abstracts, International Bibliography of the Social Sciences (IBSS), PsycINFO, PsycARTICLES, Health Management Information Consortium (HMIC), NHS Evidence, Cochrane Database of Systematic Reviews, Database of Abstracts of Reviews of Effects (DARE), NHS Economic Evaluation Database (NHS EED),Health Technology Assessment, the FADE library, Current Awareness Service for Health (CASH), OpenDOAR (Directory of Open Access Repositories) and Open System for Information on Grey Literature in Europe (OpenSIGLE) and Zetoc (The British Library's Electronic Table of Contents) were searched from 1 January 1980 to 12 October 2011. Publicly available documents and issues identified by National Patient Safety Agency (NPSA), NHS Litigation Authority (NHSLA) and coroners’ reports were considered. Opinions and perceptions of senior managers, ambulance staff and service users were solicited.Review methodsData were extracted from annual reports using two-stage thematic analysis, data from quality accounts were collated with safety priorities tabulated and considered using thematic analysis, NPSA incident report data were collated and displayed comparatively using descriptive statistics, claims reported to NHSLA were analysed to identify number and cost of claims from mistakes and/or poor service, and summaries of coroners’ reports were assessed using thematic analysis to identify underlying safety issues. The depth of analysis is limited by the remit of a scoping exercise and availability of data.ResultsWe identified studies exploring different aspects of safety, which were of variable quality and with little evidence to support activities currently undertaken by ambulance services. Adequately powered studies are required to address issues of patient safety in this service, and it appeared that national priorities were what determined safety activities, rather than patient need. There was inconsistency of information on attitudes and approaches to patient safety, exacerbated by a lack of common terminology.ConclusionPatient safety needs to become a more prominent consideration for ambulance services, rather than operational pressures, including targets and driving the service. Development of new models of working must include adequate training and monitoring of clinical risks. Providers and commissioners need a full understanding of the safety implications of introducing new models of care, particularly to a mobile workforce often isolated from colleagues, which requires a body of supportive evidence and an inherent critical evaluation culture. It is difficult to extrapolate findings of clinical studies undertaken in secondary care to ambulance service practice and current national guidelines often rely on consensus opinion regarding applicability to the pre-hospital environment. Areas requiring further work include the safety surrounding discharging patients, patient accidents, equipment and treatment, delays in transfer/admission to hospital, and treatment and diagnosis, with a clear need for increased reliability and training for improving handover to hospital.FundingThe National Institute for Health Research Health Services and Delivery Research programme.

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
In the setting of traumatic cardiopulmonary arrest, protocols that direct emergency medical service (EMS) providers to withhold or terminate resuscitation, when clinically indicated, have the potential to decrease unnecessary use of warning lights and sirens and save valuable public health resources. Protocols to withhold resuscitation should be based on the determination that there are no obvious signs of life, the injuries are obviously incompatible with life, there is evidence of prolonged arrest, and there is a lack of organized electrocardiographic activity. Termination of resuscitation is indicated when there are no signs of life and no return of spontaneous circulation despite appropriate field EMS treatment that includes minimally interrupted cardiopulmonary resuscitation. Further research is needed to determine the appropriate duration of cardiopulmonary resuscitation before termination of resuscitation and the proper role of direct medical oversight in termination of resuscitation protocols. This article is the resource document to the position statements, jointly endorsed by the National Association of EMS Physicians and the American College of Surgeons' Committee on Trauma, on withholding and termination of resuscitation in traumatic cardiopulmonary arrest.

Abstract
BACKGROUND Advanced Life Support (ALS) providers may perform more invasive prehospital procedures, while Basic Life Support (BLS) providers offer stabilisation care and often "scoop and run". We hypothesised that prehospital interventions by urban ALS providers prolong prehospital time and decrease survival in penetrating trauma victims. STUDY DESIGN We prospectively analysed 236 consecutive ambulance-transported, penetrating trauma patients an our urban Level-1 trauma centre (6/2008-12/2009). Inclusion criteria included ICU admission, length of stay >/=2 days, or in-hospital death. Demographics, clinical characteristics, and outcomes were compared between ALS and BLS patients. Single and multiple variable logistic regression analysis determined predictors of hospital survival. RESULTS Of 236 patients, 71% were transported by ALS and 29% by BLS. When ALS and BLS patients were compared, no differences in age, penetrating mechanism, scene GCS score, Injury Severity Score, or need for emergency surgery were detected (p>0.05). Patients transported by ALS units more often underwent prehospital interventions (97% vs. 17%; p<0.01), including endotracheal intubation, needle thoracostomy, cervical collar, IV placement, and crystalloid resuscitation. While ALS ambulance on-scene time was significantly longer than that of BLS (p<0.01), total prehospital time was not (p=0.98) despite these prehospital interventions (1.8 ± 1.0 per ALS patient vs. 0.2 ± 0.5 per BLS patient; p<0.01). Overall, 69.5% ALS patients and 88.4% of BLS patients (p<0.01) survived to hospital discharge. CONCLUSION Prehospital resuscitative interventions by ALS units performed on penetrating trauma patients may lengthen on-scene time but do not significantly increase total prehospital time. Regardless, these interventions did not appear to benefit our rapidly transported, urban penetrating trauma patients.

Abstract
BACKGROUND Major trauma is the leading worldwide cause of death in young adults. The mortality from traumatic cardiac arrest remains high but survival with good neurological outcome from cardiopulmonary arrest following major trauma has been regularly reported. Rapid, effective intervention is required to address potential reversible causes of traumatic cardiac arrest if the victim is to survive. Current ILCOR guidelines do not contain a standard algorithm for management of traumatic cardiac arrest. We present a simple algorithm to manage the major trauma patient in actual or imminent cardiac arrest. METHODS We reviewed the published English language literature on traumatic cardiac arrest and major trauma management. A treatment algorithm was developed based on this and the experience of treatment of more than a thousand traumatic cardiac arrests by a physician - paramedic pre-hospital trauma service. RESULTS The algorithm addresses the need treat potential reversible causes of traumatic cardiac arrest. This includes immediate resuscitative thoracotomy in cases of penetrating chest trauma, airway management, optimising oxygenation, correction of hypovolaemia and chest decompression to exclude tension pneumothorax. CONCLUSION The requirement to rapidly address a number of potentially reversible pathologies in a short time period lends the management of traumatic cardiac arrest to a simple treatment algorithm. A standardised approach may prevent delay in diagnosis and treatment and improve current poor survival rates.

Abstract
Background: Chest trauma is responsible for 50% of deaths due to trauma. This kind of death usually occurs immediately after the trauma has occurred. Objectives: The aim of this study was to evaluate the various aspects of chest trauma in patients admitted to two main trauma centers located in the Isfahan Province, Iran. Patients and Methods: During a six month period, a cross-sectional study of 100 patients who had sustained a chest injury was carried out. Data, including; age, sex, time of accident, trauma mechanism, organ injury, hospitalization length, complications, and patient outcomes were recorded and analyzed. Results: The mean ages of the patients were 24.7 ± 3.1 years. Men were injured four times more often than the women. Blunt trauma was the most common type of injury. The incidence of hemothorax was 38% in blunt traumas, and 45% (P = 0.01) in penetrating ones. The incidence of pneumothorax was 43% in blunt traumas and 20% in penetrating ones (P = 0.03). The length of hospitalization was 7.2 ± 3.2 days for blunt and 10.1 ± 3.1 days for penetrating chest traumas. Five patients (5%) died during hospitalization, three of those deaths were due to arterial injuries and two cases were due to lung contusions. Conclusions: Since hemothorax is the main complication of blunt chest trauma in young men, we recommend that special consideration needs to be made to any case of chest trauma, especially blunt chest injuries.

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.

Emergency medical services transport decisions in posttraumatic circulatory arrest: are national practices congruent? ACTA ACUST UNITED AC 2011; 69:1154-9; discussion 1160.

Abstract
OBJECTIVE To catalog the 9-1-1 emergency medical services (EMS) transport practices for posttraumatic circulatory arrest patients (PTCAPs) in the majority of the nation's largest municipalities and to compare those practices to guidelines recommended by the National Association of EMS Physicians (NAEMSP) and American College of Surgeons Committee on Trauma (ACSCOT). METHODS A survey was conducted in 33 of the nation's largest cities primarily to determine whether or not individual EMS systems transport PTCAPs to hospitals and, if so, whether or not the initial electrocardiographic (ECG) rhythm or mechanism of injury affected those transport decisions. RESULTS All 33 cities (100%) responded. Seven (21%) indicated that EMS would transport an "asystolic blunt trauma patient" emergently or "leave the transport decision to paramedic judgment" despite NAEMSP-ACSCOT guidelines to terminate resuscitation in such cases. Likewise, 15 (46%) of the 33 EMS agencies would transport "asystolic penetrating trauma patients" emergently. Similarly, 27 (82%) would transport penetrating injury patients and 20 (61%) would transport blunt trauma patients with persistent ECG activity but no palpable pulses. However, only five systems had policies that included a minimum ECG heart rate criterion for transport, and all agencies that monitor ECG (n = 32) would transport PTCAPs found with ventricular fibrillation. CONCLUSIONS Many of the nation's highest volume EMS systems transport certain PTCAPs emergently, contrary to NAEMSP-ACSCOT guidelines to terminate resuscitative efforts in such cases. Reasons for these discrepancies should be evaluated to help better delineate applicable consensus guidelines for large urban EMS agencies.
