Emergency Thoracotomy Saves Lives in a Scandinavian Hospital Setting

A critical appraisal of emergency resuscitative thoracotomy in a Western European level 1 trauma centre: a 13-year experience

Emergency Resuscitative Thoracotomy (ERT) is a lifesaving procedure in selected patients. Outcome mostly in blunt trauma is believed to be poor. The primary aim of this study was to determine the predictors of postoperative mortality following ERT. We retrospectively reviewed 34 patients ≥ 18 years who underwent ERT at San Camillo-Forlanini Hospital (Rome, Italy) between January 2009 and December 2022 with traumatic arrest for blunt or penetrating injuries. Of 34 ERT, 28 (82.4%) were for blunt trauma and 6 (17.6%) were for penetrating trauma. Injury Severity Score (p-value 0.014), positive E-FAST (p-value 0.023), Systolic Blood Pressure (p-value 0.001), lactate arterial blood (p-value 0.012), pH arterial blood (p-value 0.007), and bicarbonate arterial blood (p-value < 0.001) were significantly associated with postoperative mortality in a univariate model. After adjustment, the only independent predictor of postoperative mortality was Injury Severity Score (p-value 0.048). Our experience suggests that ERT is a technique that should be utilized for patients with critical penetrating injuries and blunt trauma in patients in extremis. Our study highlights as negative prognostic factors high values of ISS and lactate arterial blood, a positive E-FAST, and low values of Systolic Blood Pressure, pH arterial blood and bicarbonate arterial blood.

The Impact of Out-of-Hospital Time and Prehospital Intubation on Return of Spontaneous Circulation following Resuscitative Thoracotomy in Traumatic Cardiac Arrest

INTRODUCTION

Resuscitative thoracotomy (RT) is a critical procedure performed in certain trauma patients in extremis, with extremely low survival rates. Currently, there is a paucity of data pertaining to prehospital variables and their predictive role in survival outcomes in traumatic cardiac arrest (TCA) patients requiring RT. The aim of the study was to determine the impact of prehospital intubation and out-of-hospital time (OOHT) on return of spontaneous circulation (ROSC) and survival in TCA requiring RT.

METHODS

This was a retrospective cohort study of trauma patients presenting to two level-1 trauma centers, St. Michael's Hospital and Sunnybrook Health Sciences Center, in Toronto, Canada (January 1, 2005-December 31, 2020). Our exposures of interest were any prehospital intubation attempt and OOHT. Primary and secondary outcome measures were ROSC post-RT and survival to hospital discharge, respectively, and data analysis was performed using univariate logistic regression.

RESULTS

A total of 195 patients were included, of which 86% were male, and the mean age was 33 years. ROSC and survival to hospital discharge were achieved in 30% and 5% of patients, respectively. Of those who survived to discharge, 89% sustained penetrating trauma. There was no association between OOHT and ROSC (OR = 1.00, 95% CI 0.97-1.03) or survival (OR = 0.99, 95% CI 0.94-1.05). The odds of ROSC were lower in penetrating trauma in the presence of any prehospital intubation attempt (OR = 0.39, 95% CI 0.19-0.82, p = 0.01). ROSC was less likely among all patients with no prehospital signs of life (SOL) compared to those who had prehospital SOL (OR = 0.30, 95% CI 0.13-0.69, p < 0.01).

CONCLUSIONS

There was a significant association between prehospital intubation and lower likelihoods of ROSC in the penetrating TCA population requiring RT, as well as with the absence of prehospital SOL in all patients. OOHT did not appear to significantly impact ROSC or survival.

Structured and Systematic Team and Procedure Training in Severe Trauma: Going from 'Zero to Hero' for a Time-Critical, Low-Volume Emergency Procedure Over Three Time Periods

Background

Resuscitative emergency thoracotomy is a potential life-saving procedure but is rarely performed outside of busy trauma centers. Yet the intervention cannot be deferred nor centralized for critically injured patients presenting in extremis. Low-volume experience may be mitigated by structured training. The aim of this study was to describe concurrent development of training and simulation in a trauma system and associated effect on one time-critical emergency procedure on patient outcome.

Methods

An observational cohort study split into 3 arbitrary time-phases of trauma system development referred to as ‘early’, ‘developing’ and ‘mature’ time-periods. Core characteristics of the system is described for each phase and concurrent outcomes for all consecutive emergency thoracotomies described with focus on patient characteristics and outcome analyzed for trends in time.

Results

Over the study period, a total of 36 emergency thoracotomies were performed, of which 5 survived (13.9%). The “early” phase had no survivors (0/10), with 2 of 13 (15%) and 3 of 13 (23%) surviving in the development and mature phase, respectively. A decline in ‘elderly’ (>55 years) patients who had emergency thoracotomy occurred with each time period (from 50%, 31% to 7.7%, respectively). The gender distribution and the injury severity scores on admission remained unchanged, while the rate of patients with signs on life (SOL) increased over time.

Conclusion

The improvement over time in survival for one time-critical emergency procedure may be attributed to structured implementation of team and procedure training. The findings may be transferred to other low-volume regions for improved trauma care.

Performance and outcome evaluation of emergency resuscitative thoracotomy in a Norwegian trauma centre: a population-based consecutive series with survival benefits

BACKGROUND

Emergency resuscitative thoracotomy (ERT) is a lifesaving procedure for select indications in severely injured patients. The main body of the literature stem from regions with a high prevalence of penetrating injuries, while data from European institutions remain scarce. We aimed to evaluate a decade of ERT in a Norwegian trauma centre.

METHODS

A prospectively collected series from the institutional trauma registry of all consecutive trauma patients who had an ERT at Stavanger University Hospital (SUH) from 2006 to 2018. Data were extracted using both registry and electronic patient record (EPR) data, including injury profile, demographics and outcomes. Comparison of groups were done by descriptive statistics.

RESULTS

A total of 26 ERTs were performed during the study period, of which 20 were men (75%) and 6 women (25%). Five patients (19%) survived to hospital discharge, of which 3 men and 2 women with a median age of 46 years (range 24-68). All survivors had thoracic injury as location of major injury (LOMI.). Of the five survivors, four suffered blunt injury and one patient penetrating injury. At one-year of follow-up of the survivors, three patients scored 8/8 on Glasgow outcome scale-extended, 1 patient scored 7/8 and one patient 5/8.

CONCLUSION

In this study, ERT conferred good outcome with survival in one of every five procedures. Performing ERT in severely injured patients presenting in extremis appears to be justified even in low-volume centres and in blunt trauma.

Emergency department thoracotomy of severely injured patients: an analysis of the TraumaRegister DGU®

AIM OF THE STUDY

Emergency department thoracotomy (EDT) may be the last chance for survival in some severe thoracic trauma. This study investigates a representative collective with the aim to compare the findings in Europe to the international experience. Moreover, the influence of different levels of trauma care is investigated.

METHODS

All emergency thoracotomies in patients with an ISS ≥ 9 from TR-DGU (2009-2014) within the first 60 min after arrival were identified. EDTs were identified separately, and mini thoracotomies and drainage systems were excluded.

RESULTS

99,013 patients with sufficient data were observed. 1736 (1.8%) received thoracotomy during their hospital stay. 887 patients had a thoracotomy within the first hour in the emergency department (ED). 52.5% were treated in supraregional trauma centers (STC), 36.4% in regional (RTC) and 11.0% in local trauma centers (LTC). The mortality rates were 39.4% (STC), 20.9% (RTC) and 20.8% (LTC). The overall mortality rate showed no significant differences for blunt (28.2%) and penetrating trauma (31.3%). In case of cardiac arrest in the ED, a survival rate of 4.8% for blunt trauma and 20.7% for penetrating trauma was determined if EDT was carried out. Those patients showed a higher rate in severe thoracic organ injuries due to penetrating trauma but less extrathoracic injuries.

CONCLUSION

Just over half of EDTs were performed in STC. Emergency room resuscitation followed by EDT had survival rates of 4.8% and 20.7% for blunt and penetrating trauma patients, respectively.

Outcomes and indications for emergency thoracotomy after adoption of a more liberal policy in a western European level 1 trauma centre: 8-year experience

The role of emergency thoracotomy (ET) in blunt trauma is still a matter of debate and in Europe only a small number of studies have been published. We report our experience about ET both in penetrating and blunt trauma, discussing indications, outcomes and proposing an algorithm for patient selection. We retrospectively analysed patients who underwent ET at Maggiore Hospital Trauma Center over two periods: from January 1st, 2010 to December 31st, 2012, and from January 1st, 2013 to May 31st, 2017. Demographic and clinical data, mechanism of injury, Injury Severity Score, site of injury, time of witnessed cardiac arrest, presence/absence of signs of life, length of stay were considered, as well as survival rate and neurological outcome. 27 ETs were performed: 21 after blunt trauma and 6 after penetrating trauma. Motor vehicle accident was the main mechanism of injury, followed by fall from height. The mean age was 40.5 years and the median Injury Severity Score was of 40. The most frequent injury was cardiac tamponade. The overall survival rate was 10% during the first period and 23.5% during the second period, after the adoption of a more liberal policy. No long-term neurological sequelae were reported. The outcomes of ET in trauma patient, either after penetrating or blunt trauma, are poor but not negligible. To date, only small series of ET from European trauma centres have been published, although larger series are available from USA and South Africa. However, in selected patients, all efforts must be made for the patient’s survival; the possibility of organ donation should be taken into consideration as well.

A systematic review of 3251 emergency department thoracotomies: is it time for a national database?

PURPOSE

Emergency department thoracotomy (EDT) is a potentially life-saving procedure, performed on patients suffering traumatic cardiac arrest. Multiple indications have been reported, but overall survival remains unclear for each indication. The objective of this systematic review is to determine overall survival, survival stratified by indication, and survival stratified by geographical location for patients undergoing EDT across the world.

METHODS

Articles published between 2000 and 2016 were identified which detailed outcomes from EDT. All articles referring to pre-hospital, delayed, or operating room thoracotomy were excluded. Pooled odds ratios (OR) were calculated comparing differing indications.

RESULTS

Thirty-seven articles, containing 3251 patients who underwent EDT, were identified. There were 277 (8.5%) survivors. OR demonstrate improved survival for; penetrating vs blunt trauma (OR 2.10; p 0.0028); stab vs gun-shot (OR 5.45; p < 0.0001); signs of life (SOL) on admission vs no SOL (OR 5.36; p < 0.0001); and SOL in the field vs no SOL (OR 19.39; p < 0.0001). Equivalence of survival was demonstrated between cardiothoracic vs non-cardiothoracic injury (OR 1.038; p 1.000). Survival was worse for USA vs non-USA cohorts (OR 1.59; p 0.0012).

CONCLUSIONS

Penetrating injury remains a robust indication for EDT. Non-cardiothoracic cause of cardiac arrest should not preclude EDT. In the absence of on scene SOL, survival following EDT is extremely unlikely. Survival is significantly higher in the non-USA publications; reasons for this are highly complex. A UK multicentre prospective study which collects standardised data on all EDTs could provide robust evidence for better patient stratification.

Impact of cardiopulmonary resuscitation time on the effectiveness of emergency department thoracotomy after blunt trauma

PURPOSE

Debate remains about the threshold cardiopulmonary resuscitation (CPR) duration associated with futile emergency department thoracotomy (EDT). To validate the CPR duration associated with favorable outcomes, we investigated the relationship between CPR duration and return of spontaneous circulation (ROSC) after EDT in blunt trauma.

METHODS

A retrospective observational study was conducted at three tertiary centers over the last 7 years. We included bluntly injured adults who were pulseless and required EDT at presentation, but excluded those with devastating head injuries. After multivariate logistic regression identified the CRP duration as an independent predictor of ROSC, receiver operating characteristic curves were used to determine the threshold CPR duration. Patient data were divided into short- and long-duration CPR groups based on this threshold, and we developed a propensity score to estimate assignment to the short-duration CPR group. The ROSC rates were compared between groups after matching.

RESULTS

Forty patients were eligible for this study and ROSC was obtained in 12. The CPR duration was independently associated with the achievement of ROSC [odds ratio 1.18; 95% confidence interval (CI) 1.01-1.37, P = 0.04], and the threshold CPR duration was 17 min. Among the 14 patients with a short CPR duration, 13 matched with the patients with a long CPR duration, and a short CPR duration was significantly associated with higher rates of ROSC (odds ratio 8.80; 95% CI 1.35-57.43, P = 0.02).

CONCLUSIONS

A CPR duration < 17 min is independently associated with higher ROSC rates in patients suffering blunt trauma.

Retrospective study of thoracotomy performed in a French level 1-trauma center

OBJECTIVE

Resuscitative thoracotomy, a potentially life-saving procedure, is used exceptionally, and essentially for penetrating trauma. Most of the available literature is American while reports from Europe are sparse. We report our experience in a French level 1-trauma center.

MATERIAL AND METHODS

Patient records (patient age, gender, mechanism of injury, indication for emergency thoracotomy, anatomic injuries, interventions and survival) for all patients who underwent emergency thoracotomy between January 2005 and December 2015 were analyzed.

RESULTS

Twenty-two patients (19 males) underwent emergency thoracotomy. Median age was 27.5 (12-67) years. Twelve were performed for blunt trauma (55%) and 10 for penetrating injuries (45%). Thirteen patients presented with cardiac arrest, while nine had deep and refractory hypotension. Overall, survival was 32% (n=7). There were no survivors in the blunt trauma group while seven of ten with penetrating injuries survived. All patients presenting with cardiac arrest died.

CONCLUSION

The survival rate in this French retrospective study was in accordance with the literature.

Resuscitation thoracotomy

Resuscitation thoracotomy is a rarely performed procedure whose use, in France, remains marginal. It has five specific goals that correspond point-by-point to the causes of traumatic cardiac arrest: decompression of pericardial tamponade, control of cardiac hemorrhage, performance of internal cardiac massage, cross-clamping of the descending thoracic aorta, and control of lung injuries and other intra-thoracic hemorrhage. This approach is part of an overall Damage Control strategy, with a targeted operating time of less than 60minutes. It is indicated for patients with cardiac arrest after penetrating thoracic trauma if the duration of cardio-pulmonary ressuscitation (CPR) is <15minutes, or <10minutes in case of closed trauma, and for patients with refractory shock with systolic blood pressure <65mm Hg. The overall survival rate is 12% with a 12% incidence of neurological sequelae. Survival in case of penetrating trauma is 10%, but as high as 20% in case of stab wounds, and only 6% in case of closed trauma. As long as the above-mentioned indications are observed, resuscitation thoracotomy is fully justified in the event of an afflux of injured victims of terrorist attacks.

The pre-hospital management of life-threatening chest injuries: A consensus statement from the Faculty of Pre-Hospital Care, Royal College of Surgeons of Edinburgh

‘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.

Outcomes of abdominal trauma patients with hemorrhagic shock requiring emergency laparotomy: efficacy of intra-aortic balloon occlusion

Aim

The aims of this study were to investigate outcomes of abdominal trauma in patients with hemorrhagic shock requiring emergency laparotomy and clarify the beneficial effects of intra-aortic balloon occlusion (IABO) for intra-abdominal hemorrhage in patients with critically uncontrollable hemorrhagic shock (CUHS).

Methods

We reviewed 44 hemorrhagic shock patients who underwent emergency laparotomy for intra-abdominal hemorrhage over a 6-year period. Of these patients, we examined data for 19 subjects who underwent IABO during initial resuscitation to control massive intra-abdominal bleeding leading to CUHS.

Results

The average Injury Severity Score and probability of survival (Ps) of the 44 patients were 27.6 ± 15.4 and 0.735 ± 0.304, respectively, and the overall survival rate was 77.3%. The differences in the Glasgow Coma Scale, lactate level, prothrombin time - international normalized ratio, and Ps between the two groups (21 responders and 23 non-responders) were statistically significant (P < 0.05). Intra-aortic balloon occlusion was attempted in 19 of 23 patients (82.6%) with CUHS, and there were no statistically significant differences in presenting Glasgow Coma Scale, body temperature, lactate, prothrombin time - international normalized ratio, or Revised Trauma Score between the survivors (n = 12) and non-survivors (n = 7). The only significant differences between these two groups were observed in Injury Severity Score (P = 0.047) and Ps (P = 0.007). In all patients, the balloons were successfully placed in 8.1 ± 3.3 min in the thoracic aorta, and a significant increase in systolic blood pressure was observed immediately after IABO.

Conclusion

The IABO procedure can be life-saving in the management of patients with CUHS arising from intra-abdominal hemorrhage, permitting transport to surgery.

Indication for resuscitative thoracotomy in thoracic injuries-Adherence to the ATLS guidelines. A forensic autopsy based evaluation

BACKGROUND

The appropriate indications for Resuscitative Thoracotomy (RT) are still debated in the literature and various guidelines have been proposed. This study aimed to evaluate whether Advanced Trauma Life Support (ATLS) guidelines for RT were applied correctly and to evaluate the proportion of deceased patients with potentially reversible thoracic lesions (PRTL).

METHODS

The database at the Department of Forensic Medicine at Copenhagen University was queried for autopsy cases with thoracic lesions indicated by the SNOMED autopsy coding system. Patients were included if thoracic lesions were caused by a traumatic event with trauma team activation. Patient cases were blinded for any surgical intervention and evaluated independently by two reviewers for indications or contraindications for RT as determined by the ATLS guidelines. Second, autopsy reports were evaluated for the presence of PRTL.

RESULTS

Sixty-seven patients met the inclusion criteria. Two were excluded due to insufficient data. The overall agreement with guidelines was 86% and 77% for blunt and penetrating trauma, respectively. For patients submitted to RT the overall agreement with guidelines was 63% being 45% and 74% for blunt and penetrating trauma, respectively. For patients who did not undergo RT the agreement with guidelines was 100%. In all cases where RT was performed in agreement between guidelines and the clinical decision the autopsy reports showed PRTL in 16 (84%) patients. In cases of non-agreement PRTL were found in 9 (82%) patients.

CONCLUSIONS

Agreement with ATLS guidelines for RT was 63% for intervention and 100% for non-intervention in deceased patients with thoracic trauma. Agreement was higher for penetrating trauma than for blunt trauma. The adherence to guidelines did not improve the ability to predict autopsy findings of PRTL. Although the study has methodical limitations it represents a novel approach to the evaluation of the clinical use of RT guidelines.

Comparative Effectiveness of Emergency Resuscitative Thoracotomy versus Closed Chest Compressions among Patients with Critical Blunt Trauma: A Nationwide Cohort Study in Japan

BACKGROUND

Although emergency resuscitative thoracotomy is performed as a salvage maneuver for critical blunt trauma patients, evidence supporting superior effectiveness of emergency resuscitative thoracotomy compared to conventional closed-chest compressions remains insufficient. The objective of this study was to investigate whether emergency resuscitative thoracotomy at the emergency department or in the operating room was associated with favourable outcomes after blunt trauma and to compare its effectiveness with that of closed-chest compressions.

METHODS

This was a retrospective nationwide cohort study. Data were obtained from the Japan Trauma Data Bank for the period between 2004 and 2012. The primary and secondary outcomes were patient survival rates 24 h and 28 d after emergency department arrival. Statistical analyses were performed using multivariable generalized mixed-effects regression analysis. We adjusted for the effects of different hospitals by introducing random intercepts in regression analysis to account for the differential quality of emergency resuscitative thoracotomy at hospitals where patients in cardiac arrest were treated. Sensitivity analyses were performed using propensity score matching.

RESULTS

In total, 1,377 consecutive, critical blunt trauma patients who received cardiopulmonary resuscitation in the emergency department or operating room were included in the study. Of these patients, 484 (35.1%) underwent emergency resuscitative thoracotomy and 893 (64.9%) received closed-chest compressions. Compared to closed-chest compressions, emergency resuscitative thoracotomy was associated with lower survival rate 24 h after emergency department arrival (4.5% vs. 17.5%, respectively, P < 0.001) and 28 d after arrival (1.2% vs. 6.0%, respectively, P < 0.001). Multivariable generalized mixed-effects regression analysis with and without a propensity score-matched dataset revealed that the odds ratio for an unfavorable survival rate after 24 h was lower for emergency resuscitative thoracotomy than for closed-chest compressions (P < 0.001).

CONCLUSIONS

Emergency resuscitative thoracotomy was independently associated with decreased odds of a favorable survival rate compared to closed-chest compressions.

The role for surgery in pre-hospital care

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.

Resuscitative thoracotomy in penetrating trauma

The resuscitative thoracotomy (RT) is an important procedure in the management of penetrating trauma. As it is performed only in patients with peri-arrest physiology or overt cardiac arrest, survival is low. Experience is also quite variable depending on volume of penetrating trauma in a particular region. Survival ranges from 0% to as high as 89% depending on patient selection, available resources, and location of RT (operating or emergency rooms). In this article, published guidelines are reviewed as well as outcomes. Technical considerations of RT and well as proper training, personnel, and location are also discussed.

An evidence-based approach to patient selection for emergency department thoracotomy: A practice management guideline from the Eastern Association for the Surgery of Trauma

BACKGROUND

Within the GRADE (Grading of Recommendations Assessment, Development and Evaluation) framework, we performed a systematic review and developed evidence-based recommendations to answer the following PICO (Population, Intervention, Comparator, Outcomes) question: should patients who present pulseless after critical injuries (with and without signs of life after penetrating thoracic, extrathoracic, or blunt injuries) undergo emergency department thoracotomy (EDT) (vs. resuscitation without EDT) to improve survival and neurologically intact survival?

METHODS

All patients who underwent EDT were included while those involving either prehospital resuscitative thoracotomy or operating room thoracotomy were excluded. Quantitative synthesis via meta-analysis was not possible because no comparison or control group (i.e., survival or neurologically intact survival data for similar patients who did not undergo EDT) was available for the PICO questions of interest.

RESULTS

The 72 included studies provided 10,238 patients who underwent EDT. Patients presenting pulseless after penetrating thoracic injury had the most favorable EDT outcomes both with (survival, 182 [21.3%] of 853; neurologically intact survival, 53 [11.7%] of 454) and without (survival, 76 [8.3%] of 920; neurologically intact survival, 25 [3.9%] of 641) signs of life. In patients presenting pulseless after penetrating extrathoracic injury, EDT outcomes were more favorable with signs of life (survival, 25 [15.6%] of 160; neurologically intact survival, 14 [16.5%] of 85) than without (survival, 4 [2.9%] of 139; neurologically intact survival, 3 [5.0%] of 60). Outcomes after EDT in pulseless blunt injury patients were limited with signs of life (survival, 21 [4.6%] of 454; neurologically intact survival, 7 [2.4%] of 298) and dismal without signs of life (survival, 7 [0.7%] of 995; neurologically intact survival, 1 [0.1%] of 825).

CONCLUSION

We strongly recommend that patients who present pulseless with signs of life after penetrating thoracic injury undergo EDT. We conditionally recommend EDT for patients who present pulseless and have absent signs of life after penetrating thoracic injury, present or absent signs of life after penetrating extrathoracic injury, or present signs of life after blunt injury. Lastly, we conditionally recommend against EDT for pulseless patients without signs of life after blunt injury.

Emergency resuscitative thoracotomy performed in European civilian trauma patients with blunt or penetrating injuries: a systematic review

PURPOSE

Emergency resuscitative thoracotomy (ERT) is a lifesaving procedure in selected patients. Indications are still being debated, but outcome in blunt trauma is believed to be poor. Recent reports from European populations, where blunt trauma predominates, have suggested favorable outcome also in blunt trauma. Our aim was to identify all European studies reported over the last decade and compare reported outcomes to existing knowledge.

METHODS

We performed a systematic literature search according to PRISMA guidelines (January 1st, 2004 to December 31st, 2014). The "grey literature" was included by searching Google Scholar. Qualitative comparison of studies and outcomes was done.

RESULTS

A total of 8 articles from Europe were included originating from Croatia, Norway (n = 2), Denmark, Iceland, the Netherlands, Scotland, and Switzerland. Of 376 resuscitative thoracotomies, 193 (51.3 %) were for blunt trauma. Male:female distribution was 3.5:1. The collectively reported overall survival was 42.8 % (n = 161), with 25.4 % (49 of 193) blunt trauma and 61.2 % (112 of 183) penetrating injuries. When strictly including those ERTs designated as done in the emergency department for blunt mechanism (n = 139) only, a total of 18 patients survived (12.9 %). Survival after EDTs for penetrating trauma was 41.6 % (37 of 89). Neurological outcome (reported in 5 of 8 studies) reported favorable neurological long-term outcome in the majority of survivors, even after blunt trauma. None referred to Glasgow Outcome Score. Heterogeneity in the studies prevented outcome analyses by formal quantitative meta-analysis.

CONCLUSION

The reported outcome after ERT in European civilian trauma populations is favorable, with one in every four ERTs in the ED surviving. Notably, outcome is at variance with previously reported collective data, in particular for blunt trauma. Multicenter, prospective, observational data are needed to validate the modern role of ERT in blunt trauma.

Basic data underlying clinical decision-making and outcomes in emergency department thoracotomy: tabular review

BACKGROUND

Emergency department thoracotomy (EDT) is a formidable and dramatic last attempt by the trauma surgeon to save the life of a patient in extremis. The aim of this report is to provide a benchmark for comparison with past results by reviewing all available published data since the American College of Surgeons Committee on Trauma review article in 2001, which reviewed literature from 1966 to 1999 regarding indications for and outcomes of EDT.

METHODS

A comprehensive literature search in MEDLINE Library databases was performed for EDT. Data were extracted by three independent reviewers.

RESULTS

We identified 37 papers with a total of 3466 patients. A total of 85.2% (1720 of the 2018) had penetrating trauma, 58.3% (372 of the 638) had cardiac injuries, 43.0% (251 of the 584) had thoracic injuries and 26.2% (143 of the 546) had abdominal injuries. The overall rate survival in this review was 8% (267 of the 3466, range 0-33.3%). Of 25 papers reporting cases of EDT for penetrating traumas, their survival rate was 9.8% (169 of the 1719, range 0-45.5); similarly, of 14 papers assessing EDT for blunt injuries, the survival rate was 5.2% (24 of the 460, range 0-12.2). Of 15 papers reporting neurological outcomes 84.6% (143 of the 169, range 50-100%) of patients returned to baseline. The survival outcome of EDT in US experience versus non-US experiences was 6.3% (164 of the 2612, range 0-14.9) versus 11.9% (89 of the 745, range 0-33.3) respectively.

CONCLUSION

The authors intend this review to serve as a practical and prompt literature search tool for all surgeons who encounter resuscitative thoracotomy in their practice.

Survival predictor for penetrating cardiac injury; a 10-year consecutive cohort from a scandinavian trauma center

BACKGROUND

Penetrating cardiac injuries in Europe have been poorly studied. We present a 10-year outcome for patients with penetrating heart injuries at Oslo University Hospital.

METHODS

Data from 01.01.2001 until 31.12.2010 was collected from the Oslo University Hospital Trauma Registry and from the patients' records.

RESULTS

Thirty-one patients were admitted with a penetrating cardiac injury. Fourteen patients survived (45%). Four out of 8 patients (50%) with gunshot wounds survived compared to 10 out of 23 (44%) with stab wounds. Median (quartiles) for the following values were: Injury Severity Score 25 (21-35), Revised Trauma Score 0 (0-6,9), Probability of Survival 0,015 (0,004-0,956), Glasgow Coma Scale 3 (3-13). Thirteen patients had signs of life on admission and survived. Eighteen patients were admitted without signs of life and received emergency department thoracotomy. Eight of these had no signs of life at the scene of injury and did not survive. Out of the remaining 10 patients, one survived.

CONCLUSIONS

The outcome of patients with penetrating cardiac injury reaching the emergency department with signs of life was excellent. Hemodynamic instability indicates immediate surgery. Stable patients with penetrating thoracic trauma and possible cardiac injury detected by imaging should be considered for conservative treatment.

Surgical management for the first 48 h following blunt chest trauma: state of the art (excluding vascular injuries)

This review aims to answer the most common questions in routine surgical practice during the first 48 h of blunt chest trauma (BCT) management. Two authors identified relevant manuscripts published since January 1994 to January 2014. Using preferred reporting items for systematic reviews and meta-analyses statement, they focused on the surgical management of BCT, excluded both child and vascular injuries and selected 80 studies. Tension pneumothorax should be promptly diagnosed and treated by needle decompression closely followed with chest tube insertion (Grade D). All traumatic pneumothoraces are considered for chest tube insertion. However, observation is possible for selected patients with small unilateral pneumothoraces without respiratory disease or need for positive pressure ventilation (Grade C). Symptomatic traumatic haemothoraces or haemothoraces >500 ml should be treated by chest tube insertion (Grade D). Occult pneumothoraces and occult haemothoraces are managed by observation with daily chest X-rays (Grades B and C). Periprocedural antibiotics are used to prevent chest-tube-related infectious complications (Grade B). No sign of life at the initial assessment and cardiopulmonary resuscitation duration >10 min are considered as contraindications of Emergency Department Thoracotomy (Grade C). Damage Control Thoracotomy is performed for either massive air leakage or refractive shock or ongoing bleeding enhanced by chest tube output >1500 ml initially or >200 ml/h for 3 h (Grade D). In the case of haemodynamically stable patients, early video-assisted thoracic surgery is performed for retained haemothoraces (Grade B). Fixation of flail chest can be considered if mechanical ventilation for 48 h is probably required (Grade B). Fixation of sternal fractures is performed for displaced fractures with overlap or comminution, intractable pain or respiratory insufficiency (Grade D). Lung herniation, traumatic diaphragmatic rupture and pericardial rupture are life-threatening situations requiring prompt diagnosis and surgical advice. (Grades C and D). Tracheobronchial repair is mandatory in cases of tracheal tear >2 cm, oesophageal prolapse, mediastinitis or massive air leakage (Grade C). These evidence-based surgical indications for BCT management should support protocols for chest trauma management.

To be blunt: are we wasting our time? Emergency department thoracotomy following blunt trauma: a systematic review and meta-analysis

STUDY OBJECTIVE

The role of emergency department (ED) thoracotomy after blunt trauma is controversial. The objective of this review is to determine whether patients treated with an ED thoracotomy after blunt trauma survive and whether survivors have a good neurologic outcome.

METHODS

A structured search was performed with MEDLINE, EMBASE, CINAHL, and PubMed. Inclusion criteria were ED thoracotomy or out-of-hospital thoracotomy, cardiac arrest or periarrest, and blunt trauma. Outcomes assessed were mortality and neurologic result. The articles were appraised with the system designed by the Institute of Health Economics of Canada. A fixed-effects model was used to meta-analyze the data. Heterogeneity was assessed with the I(2) statistic.

RESULTS

Twenty-seven articles were included in the review. All were case series. Of 1,369 patients who underwent an ED thoracotomy, 21 (1.5%) survived with a good neurologic outcome. All 21 patients had vital signs present on scene or in the ED and a maximum duration of cardiopulmonary resuscitation of 11 to 15 minutes. Thirteen studies were included in the meta-analysis. If there were either vital signs or signs of life present in the ED, the probability of a poor outcome was 99.2% (95% confidence interval 96.4% to 99.7%).

CONCLUSION

There may be a role for ED thoracotomy after blunt trauma, but only in a limited group of patients. Good outcomes have been achieved for patients who had vital signs on admission and for patients who received an ED thoracotomy within 15 minutes of cardiac arrest. The proposed guideline should be used to determine which patients should be considered for an ED thoracotomy, according to level 4 evidence.

Resuscitative Thoracotomy: An Update

BACKGROUND

Resuscitative thoracotomy is a heroic procedure that may offer the only survival hope for trauma patients in extremis. However, this operation has been the subject of much debate and its use, feasibility, outcomes, and cost are being continuously re-evaluated.

METHODS

This is a review of the most current (after 2000) literature on resuscitative thoracotomy, based on computer database searches for studies on resuscitative thoracotomy, emergency department thoracotomy, and emergency thoracotomy. Studies were selected for inclusion in this review based on their relevance and contribution to our understanding of resuscitative thoracotomy.

RESULTS

A total of 37 studies were included, and the following resuscitative thoracotomy-related topics were critically discussed: indications, biochemical profile, long-term outcome, organ donation, pre-hospital use, military use, international aspects, intra-aortic balloon occlusion, suspended animation, and cost and occupational exposure.

CONCLUSIONS

This review demonstrates that the indications for resuscitative thoracotomy become clearer and that new information is available regarding its use in the pre-hospital urban environment and military settings. Furthermore, it points to new strategies to supplement resuscitative thoracotomy including intra-aortic balloon occlusion and suspended animation. Finally, it sheds light on the long-term outcomes, organ donation, and cost and occupational exposure following resuscitative thoracotomy.

Effects of moving emergency trauma laparotomies from the ED to a dedicated OR

Introduction

The trauma room at Oslo University Hospital- Ulleval is fully equipped for major damage control procedures, in order to minimize delay to surgery. Since 2006, patients in need of immediate laparotomy have increasingly been transferred to a dedicated trauma operating room (OR). We wanted to determine the decrease in number of procedures performed in the emergency department (ED), the effect on time from admission to laparotomy, the effect on non-therapeutic laparotomies, and finally to determine whether such a change could be undertaken without an increase in mortality.

Methods

Retrospective evaluation of haemodynamically unstable trauma patients undergoing laparotomy during the period 2002–2009. Based on time for protocol change Period 1 was defined as 2002–2006 and Period 2 as 2007–2009. Significance was set at p < 0.05.

Results

A total of 167 consecutive patients were included; 103 patients from Period 1 and 64 from Period 2. We found a 42% decrease in ED laparotomies (p < 0.001). Median time to laparotomy increased from 24.0 to 34.0 minutes from Period 1 to Period 2 (p = 0.029). Crude mortality fell from 57% to 39%. The proportion of non-therapeutic laparotomies in the OR tended to be lower over the whole study period.

Conclusion

Moving this cohort of haemodynamically compromised trauma patients in need of emergency laparotomy out of the ED to a dedicated OR resulted in longer median time to laparotomy, but did not increase mortality.

Emergency thoracotomy as a rescue treatment for trauma patients in Iceland

OBJECTIVE

Emergency thoracotomy (ET) can be life-saving in highly selected trauma patients, especially after penetrating chest trauma. There is little information on the outcome of ET in European trauma centres. Here we report our experience in Iceland.

MATERIAL AND METHODS

This was a retrospective analysis of all patients who underwent ET in Iceland between 2005 and 2010. Patient demographics, mechanism, and location of major injury (LOMI) were registered, together with signs of life (SOL), the need for cardiopulmonary resuscitation (CPR), and transfusions. Based on physiological status from injury at admission, the severity score (ISS), revised trauma score (RTS), and probability of survival (PS) were calculated.

RESULTS

Of nine ET patients (all males, median age 36years, range 20-76) there were five long-term survivors. All but one made a good recovery. There were five blunt traumas (3 survivors) and four penetrating injuries (2 survivors). The most frequent LOMI was isolated thoracic injury (n=6), but three patients had multiple trauma. Thoracotomy was performed in five patients, sternotomy in two, and two underwent both procedures. One patient was operated in the ambulance and the others were operated after arrival. Median ISS and NISS were 29 (range 16-54) and 50 (range 25-75), respectively. Median RTS was 7 (range 0-8) with estimated PS of 85% (range 1-96%). Median blood loss was 10L (range 0.9-55). A median of 23 units of packed red blood cells were transfused (range 0-112). For four patients, CPR was required prior to transport; two others required CPR in the emergency room. Three patients never had SOL and all of them died.

CONCLUSION

ET is used infrequently in Iceland and the number of patients was small. More than half of them survived the procedure. This is especially encouraging considering how severely injured the patients were.

Is there any role for resuscitative emergency department thoracotomy in blunt trauma?

A best evidence topic in cardiothoracic surgery was written according to a structured protocol. The question addressed was whether there is any role for resuscitative emergency department thoracotomy in severe blunt trauma. Emergency thoracotomy is an accepted intervention for patients with penetrating cardiothoracic trauma. However, its role in blunt trauma has been challenged and has been a subject of considerable debate. Altogether, 186 relevant papers were identified, of which 14 represented the best evidence to answer the question. The author, journal, date, country of publication and relevant outcomes are tabulated. The 14 studies comprised 2 systematic reviews and 12 retrospective studies. The systematic review performed by the Trauma Committee of the American College of Surgeons included 42 studies and a cumulative total of 2193 blunt trauma patients who underwent an emergency department thoracotomy, reporting a survival rate of 1.6%. According to this review, 15% of the survivors suffered from neurological sequelae, but survivors from both penetrating and blunt trauma were included. A systematic review comprising 24 studies reported a survival rate of 1.4% among 1047 blunt trauma patients. Of the retrospective studies, 11 report poor survival rates, ranging from 0 to 6%. Only one study reports a higher survival rate (12.2%). Five of the studies reported on the neurological outcome of survivors. The majority of the studies suffered from limitations due to the small number of included cases. The reported survival after an emergency department thoracotomy for blunt trauma is very low in the vast majority of available studies. Furthermore, the neurological sequelae in the few survivors are frequent and severe. Interestingly, some author groups recommend that emergency department thoracotomy should be contraindicated in cases of blunt trauma with no signs of life at the scene of trauma or on arrival at the emergency department. Larger, well-designed series will be required to reach a consensus on valid prognostic factors and specific subgroups of blunt trauma patients with substantial chances of survival.

How to mend a broken heart: a major stab wound of the left ventricle

A 28-year-old male admitted with a stab wound under his left nipple, underwent emergency surgery because of confusion, a decreasing blood pressure and increasing tachycardia. A median sternotomy incision was made and after establishing cardiopulmonary bypass, a 7 cm wound in the left ventricle and a smaller wound in the left atrium were repaired. An injured segment of lung was resected and the left anterior descending and circumflex arteries were grafted after weaning from cardiopulmonary bypass was initially unsuccessful. Although the patient suffered a stroke, probably due to prehospital hypoperfusion, he eventually recovered without major sequelae. In addition to the case report we present a literature review of the last 15 years pertaining the management of penetrating cardiac injury.

Emergency thoracotomies in the largest trauma center in Denmark: 10 years' experience

AIM

The aim of our study was to investigate the outcome in terms of 30-day survival and to determine whether preoperative factors could predict the outcome.

METHODS

All patients who underwent an emergency thoracotomy (ET) during the period 2000 to 2009 were included. The patients were divided into two groups: emergency department thoracotomy and operating room thoracotomy. Data on demographics, mechanism of injury, intraoperative data, Injury Severity Scores (ISS), probability of survival, signs of life, transportation time, indications, and outcome were collected.

RESULTS

Forty-four ETs were performed. The mechanisms of injury were penetrating in 28 (64%) and blunt in 16 (36%) cases. In the emergency department thoracotomy group, the survival was 45 versus 20% for penetrating and blunt trauma, respectively. The total survival was 33%. In the operating room thoracotomy group, the survival was 83%. The survivors had a significantly lower ISS and a higher calculated probability of survival. The calculated mean probability of survival was 44 and 84% in the emergency department thoracotomy and operating room thoracotomy groups, respectively. The actual survival was similar, with 33% in the emergency department thoracotomy group and 83% in the operating room thoracotomy group.

CONCLUSIONS

The probability of survival and ISS are good predictors of survival in these patients and should be included in the future in order to make upcoming studies easier to compare. Patients with very high ISS or low probability of survival survived, justifying the procedure in our center.
