Internal blood loss in fatal liver lacerations - determining lethality from relative blood loss.

Certificates of medical evidence are often used to aid the court in assessing the cause and severity of a victim's injuries. In cases with significant blood loss, the question whether the bleeding itself was life-threatening sometimes arises. To answer this, the volume classification of hypovolemic shock described in ATLS® is commonly used as an aid, where a relative blood loss > 30% is considered life-threatening. In a recent study of deaths due to internal haemorrhage, many cases had a relative blood loss < 30%. However, many included cases had injuries which could presumably cause deaths via other mechanisms, making the interpretation uncertain. To resolve remaining ambiguity, we studied whether deaths due to isolated liver lacerations had a relative blood loss < 30%, a cause of death where the mechanism of death is presumably exsanguination only. Using the National Board of Forensic Medicine autopsy database, we identified all adult decedents, who had undergone a medico-legal autopsy 2001-2021 (n = 105 952), where liver laceration was registered as the underlying cause of death (n = 102). Cases where death resulted from a combination of also other injuries (n = 79), and cases that had received hospital care, were excluded (n = 4), leaving 19 cases. The proportion of internal haemorrhage to calculated total blood volume in these fatal pure exsanguinations ranged from 12 to 52%, with 63% of cases having a proportion < 30%. Our results lend further support to the claim that the volume classification of hypovolemic shock described in ATLS® is inappropriate for assessing the degree of life-threatening haemorrhage in medico-legal cases.

Enhancing trauma care in Ukraine amid conflict: A successful implementation of the modified advanced trauma life support course in an active war zone.

BACKGROUND: Following the 2022 Russian invasion, Ukraine's healthcare system suffered extensive damage, with over 1000 medical facilities destroyed, exacerbating the trauma care crisis. The absence of standardized trauma training left Ukrainian healthcare providers ill-equipped to manage the surge in trauma cases amid conflict. To bridge this gap, we implemented advanced trauma life support (ATLS) courses in Ukraine amid active warfare, aiming to enhance trauma care expertise among healthcare professionals. METHODS: A consortium, including the International Medical Corps, Harvard Humanitarian Initiative, and others, responded to a request from the Ukrainian Ministry of Health. The ATLS curriculum, translated into Ukrainian, guided the training, with US-based instructors sent to Ukraine for teaching. Despite logistical challenges, such as missile attacks and curfews, the courses ran in multiple Ukrainian cities over 3 months. Course effectiveness was evaluated through pre- and post-course knowledge tests, self-efficacy surveys, and satisfaction assessments. RESULTS: Ten ATLS courses trained 213 Ukrainian healthcare providers across five deployments. Significant improvements in knowledge scores (p < 0.05) and enhanced self-reported confidence in trauma management were observed. Notably, no casualties were reported among instructors or students, highlighting program safety despite security challenges. CONCLUSIONS: Our study demonstrates successful ATLS course implementation in an active war zone, filling a critical gap in trauma education in Ukraine. Despite challenges, the program significantly enhanced participants' trauma care knowledge and confidence. Collaboration between international and local partners was pivotal. This model can serve as a valuable framework for trauma education globally, improving outcomes in conflict zones and resource-limited settings.

The relationship between lifestyle habits and obesity among students in the Eastern province of Saudi Arabia: using the Arab Teens Lifestyle (ATLS) questionnaire.

BACKGROUND: The Arab Teens Lifestyle (ATLS) questionnaire was an initiative to assess the lifestyle habits influencing obesity rates in the Middle East and North Africa (MENA) region, including physical activity (PA) patterns, sedentary and eating behaviours. Since its implementation, the ATLS questionnaire has been used in several studies among different age groups and populations. This instrument has not previously been administered among the university students of the Eastern Province of Saudi Arabia, where the obesity rates are the highest in the country. This research was the first that aimed to identify lifestyle habits influencing the rates of obesity among 18-25-year-old university students in the Eastern Province of the Kingdom of Saudi Arabia (KSA) using the ATLS questionnaire. METHODS: Quantitative cross-sectional research among n = 426 students of the Eastern Province of Saudi Arabia using the ATLS questionnaire. RESULTS: Out of n = 426 participants, n = 200 (47%) were categorised (using body mass index) as normal weight; n = 113 (26.5%) were overweight, and n = 73 (17.1%) were obese. The findings showed that most of the nutritional, PA, and sedentary behavioural factors (e.g., screen time) in the questionnaire were not associated with obesity status amongst the participants. In the obese group, more of the males that consumed fruits, French fries, cakes, sweets and doughnuts more than three times per week were likely to be obese, which was not the case for females. CONCLUSION: The reported lifestyles of the students could potentially lead to long-term negative health effects, which is of concern given the rising rates of overweight, obesity, and obesity-related non-communicable diseases (NCDs) among the Kingdom's adult and ageing population. Further studies are recommended to explore the knowledge, attitudes, and perceptions of Saudi students in the Eastern Province in relation to PA, sedentary behaviours, and dietary habits, along with their views on how these can be improved.

The effect of ATLS/PHTLS spinal motion restriction protocol on the incidence of spinal cord injury, a nationwide database study.

PURPOSE: To study trends in incidence and outcome of patients with traumatic spinal cord injury (TSCI) in the Netherlands before, during and after implementation of the Advanced Trauma Life Support (ATLS®) and Pre-Hospital Trauma Life Support (PHTLS®)- Spinal Motion Restriction(SMR) protocol. METHODS: In an observational database we studied national hospital admission and emergency department databases to analyse incidence rates and outcome of traumatic spinal cord injury and spinal fractures in the emergency department and in admittances in The Netherlands between 1986 and 2021. RESULTS: A significant increase of 39% in TSCI in admitted patients with spinal fractures over the past 35 years (p < 0.001). This increase was especially prevalent in cervical spinal fractures (132%), while thoracic and lumbosacral spinal fractures showed a decrease in accompanied TSCI (64% and 88% respectively). The overall increase in spinal fractures was not significant. The duration of hospital admission decreased for spinal fractures without TSCI and with TSCI (66% and 56% respectively). CONCLUSION: Since implementation of the SMR-protocol was aiming to limit TSCI in patients who suffered a spinal fracture, the increase in TSCI is an unexpected finding. Exact explanation for this increase is unclear and the contribution of the SMR-protocol is not fully understood due to confounders in the used datasets. Either way, the scientific evidence supporting this costly time- and labor-intensive SMR-protocol remains debated, along with evidence contradicting it. Therefore it stresses the need for clear, evidencebased reasoning for spinal immobilization according to ATLS, as this is currently lacking.

Virtual reality simulation to enhance advanced trauma life support trainings - a randomized controlled trial.

BACKGROUND: Advanced Trauma Life Support (ATLS) is the gold standard of initial assessment of trauma patients and therefore a widely used training program for medical professionals. Practical application of the knowledge taught can be challenging for medical students and inexperienced clinicians. Simulation-based training, including virtual reality (VR), has proven to be a valuable adjunct to real-world experiences in trauma education. Previous studies have demonstrated the effectiveness of VR simulations for surgical and technical skills training. However, there is limited evidence on VR simulation training specifically for trauma education, particularly within the ATLS curriculum. The purpose of this pilot study is to evaluate the feasibility, effectiveness, and acceptance of using a fully immersive VR trauma simulation to prepare medical students for the ATLS course. METHODS: This was a prospective randomised controlled pilot study on a convenience sample of advanced medical students (n = 56; intervention group with adjunct training using a commercially available semi-automated trauma VR simulation, n = 28, vs control group, n = 28) taking part in the ATLS course of the Military Physician Officer School. Feasibility was assessed by evaluating factors related to technical factors of the VR training (e.g. rate of interruptions and premature termination). Objective and subjective effectiveness was assessed using confidence ratings at four pre-specified points in the curriculum, validated surveys, clinical scenario scores, multiple choice knowledge tests, and ATLS final clinical scenario and course pass rates. Acceptance was measured using validated instruments to assess variables of media use (Technology acceptance, usability, presence and immersion, workload, and user satisfaction). RESULTS: The feasibility assessment demonstrated that only one premature termination occurred and that all remaining participants in the intervention group correctly stabilised the patient. No significant differences between the two groups in terms of objective effectiveness were observed (p = 0.832 and p = 0.237 for the pretest and final knowledge test, respectively; p = 0.485 for the pass rates for the final clinical scenario on the first attempt; all participants passed the ATLS course). In terms of subjective effectiveness, the authors found significantly improved confidence post-VR intervention (p < .001) in providing emergency care using the ATLS principles. Perceived usefulness in the TEI was stated with a mean of 4 (SD 0.8; range 0-5). Overall acceptance and usability of the VR simulation was rated as positive (System Usability Scale total score mean 79.4 (SD 11.3, range 0-100). CONCLUSIONS: The findings of this prospective pilot study indicate the potential of using VR trauma simulations as a feasible and acceptable supplementary tool for the ATLS training course. Where objective effectiveness regarding test and scenario scores remained unchanged, subjective effectiveness demonstrated improvement. Future research should focus on identifying specific scenarios and domains where VR can outperform or enhance traditional learning methods in trauma simulation.

Knowledge, Attidue and Practice of Advanced Trauma Life Suppoort (ATLS) Protocol among House-Officers in Khartoum State Hospitals, Sudan, 2023.

BACKGROUND: Advanced Trauma Life Support was originated mainly to train doctors who don't manage trauma on a regular basis, including junior doctors as it prepares them more efficiently and effectively for treating and managing trauma patients. This study was conducted to study knowledge, attitude and practice of advanced trauma life support protocol among house-officers in Khartoum state hospitals, Sudan 2023. METHODS: This is a cross-sectional descriptive health facility based study conducted in Bahri Teaching Hospital, Omdurman Teaching Hospital and Ibrahim Malik teaching hospital, Khartoum state, Sudan. Data of 151 House-officers of all nationality working in Khartoum state hospitals was collected using a simple random technique, filling questionnaire that was designed especially for this study. Comparison between different variables by Chi-square test and statistical significance difference at P value < 0.05 was done. RESULT: A total of 151 house officers were included in the study. 49% aged between 20 and 25 years, females were the majority 56.3%. About 41.1% have took ATLS course before. 55.21% of the study participants didn't take the course because it was not available, while 35.42% because it was expensive and 29.17% referred it to their busy lifestyle. 91% of the study population think that ATLS course should be compulsory and 85% think that the ATLS protocol should be recommended to both junior and senior doctors. 77% of the study participants stated that their seniors teaching skills affect how they apply ATLS. CONCLUSION: Overall junior doctors at Khartoum state hospitals demonstrated a positive attitude towards ATLS, but they showed poor knowledge regarding the topic. It's advised that an earlier training program is introduced by incorporating ATLS course to be part of all final year medical school's curriculum.

Development and validation of assessment instruments for cervical collar and spinal board placement in simulated environments for nursing students in the care of polytrauma patients.

BACKGROUND: Multiple trauma injuries are the leading cause of death and disability in people under the age of 45 and require prompt and specialised care. However, medical and nursing education programmes do not always include specific training in emergency pre-hospital care, resulting in a lack of basic practical skills in trauma management. OBJECTIVE: To develop and validate two instruments for assessing nursing students' competence in cervical collar and spinal board application in simulated pre-hospital emergency scenarios. METHOD: This is an instrumental study that involves the development of two assessment instruments and the evaluation of their psychometric properties in a sample of 392 nursing students. Content validity was assessed using expert judgement, by calculating the content validity ratio (CVR) for each item and the scale level content validity index average (S-CVI/Ave) for the instruments. Exploratory factor analysis using the MINRES extraction method and Promax rotation was performed to analyse the performance of the items and structure of the rubrics. Internal consistency was analysed using the Omega coefficient and inter-rater agreement was assessed using Cohen's Kappa coefficient. RESULTS: Initially, two rubrics were obtained: one with six items for cervical collar placement (S-CVI/Ave = 0.86) and one with nine items for spinal board placement (S-CVI/Ave = 0.81). Both had a single-factor structure, with all items having factor loadings greater than 0.34 for the cervical collar rubric and 0.56 for the spinal board rubric, except for item 2 of the cervical collar rubric (λ = 0.24), which was subsequently removed. The final cervical collar rubric (five items) had an overall internal consistency of 0.84 and the spinal board rubric had an overall internal consistency of 0.90, calculated using the Omega statistic. The weighted Kappa coefficient for each item ranged from acceptable (0.32) to substantial (0.79). These results show that we have successfully developed two sufficiently valid instruments to assess the immobilisation competencies proposed in the objective of the study. CONCLUSION: Whilst further research is needed to fully establish their psychometric properties, these instruments offer a valuable starting point for evaluating nursing students' competence in cervical collar and spinal board application in simulated pre-hospital scenarios.

Sedentary and physical activity time differs between self-reported ATLS-2 physical activity questionnaire and accelerometer measurements in adolescents and young adults in the United Arab Emirates.

BACKGROUND: Most young adults and adolescents in the United Arab Emirates (UAE) do not meet the established internationally recommended physical activity levels per day. The Arab Teen Lifestyle Study (ATLS) physical activity questionnaire has been recommended for measuring self-reported physical activity of Arab adolescents and young adults (aged 14 years to mid-twenties). The first version of the ATLS has been validated with accelerometers and pedometers (r ≤ 0.30). The revised version of the questionnaire (ATLS-2, 2021) needs further validation. The aim of this study was to validate the self-reported subjective sedentary and physical activity time of the ATLS-2 (revised version) physical activity questionnaire with that of Fibion accelerometer-measured data. METHODS: In this cross-sectional study, 131 healthy adolescents and young adults (aged 20.47 ± 2.16 [mean ± SD] years (range 14-25 years), body mass index 23.09 ± 4.45 (kg/m2) completed the ATLS-2 and wore the Fibion accelerometer for a maximum of 7 days. Participants (n = 131; 81% non-UAE Arabs (n = 106), 13% Asians (n = 17) and 6% Emiratis (n = 8)) with valid ATLS-2 data without missing scores and Fibion data of minimum 10 h/day for at least 3 weekdays and 1 weekend day were analyzed. Concurrent validity between the two methods was assessed by the Spearman rho correlation and Bland-Altman plots. RESULTS: The questionnaire underestimated sedentary and physical activity time compared to the accelerometer data. Only negligible to weak correlations (r ≤ 0.12; p > 0.05) were found for sitting, walking, cycling, moderate intensity activity, high intensity activity and total activity time. In addition, a proportional/systematic bias was evident in the plots for all but two (walking and moderate intensity activity time) of the outcome measures of interest. CONCLUSIONS: Overall, self-reported ATLS-2 sedentary and physical activity time had low correlation and agreement with objective Fibion accelerometer measurements in adolescents and young adults in the UAE. Therefore, sedentary and physical activity assessment for these groups should not be limited to self-reported measures.

The effect of micro-learning on trauma care knowledge and learning satisfaction in nursing students.

BACKGROUND: Despite the fact that there are few formal trauma training courses for nurses, they play an important role in the care of trauma patients. This study aims to investigate the effect of micro-learning on the knowledge of managing trauma patients and learning satisfaction in nursing students. METHODS: The convenience sampling method was used to enroll 30 final-year nursing students from Alborz University of Medical Sciences in this quasi experimental One-group pretest -posttest design. The educational content was created and repeated 4 times over the course of 36 days using a micro-learning approach through whiteboard animations, video casts, and live videos. MCQ scenario-based exam was used to assess participants' knowledge of trauma in three phases: pretest, immediately following the intervention, and one month after the end of the educational program. An e-learning satisfaction psychometric questionnaire was used to measure satisfaction. RESULTS: The mean knowledge score 1 month after the intervention did not differ significantly from the score immediately after the intervention (p = 1), but there was a significant relationship between the mean knowledge score immediately after the intervention and before that (p = 0.047). Demographic variables and knowledge of trauma management did not differ statistically significant. The majority of students were pleased with how the course was implemented (5.64). CONCLUSION: The use of micro-learning has a positive effect on the promotion and retention of knowledge of trauma care, as well as increasing nursing students' satisfaction. Micro-learning is proposed as a new educational approach that can be used as a complementary or as a stand-alone method to convey important educational concepts and increase learner satisfaction.

Proper preservation of amputated parts: A multi-level shortcoming.

BACKGROUND: Successful replantation relies on proper preservation of traumatically amputated parts. The established protocol for preservation, however, is inconsistently adhered to. The objective of this study is to examine the rate of proper preservation in multiple patient populations. METHODS: A retrospective review of patients from 2015 to 2019 at a single academic institution was conducted. Patients were included if they suffered a traumatic amputation, the amputated part was present for evaluation by the hand surgery team, and modality of preservation was documented. Additional data including method of patient transport, replantation attempt, and operative outcome were assessed. Patients were stratified based on whether proper preservation was employed and compared using chi-square tests. RESULTS: Ninety-one patients were included, thirty-one (34.1%) of whom had amputated parts which were properly preserved. Patients from referring facilities were more likely to present with properly preserved parts (45.0%) than those presenting from home (25.5%), though this did not meet significance (P = .051). In total, 74 patients arrived via EMS with 35.1% adherence to preservation protocol. Of the 31 patients who had properly preserved parts, 58.1% underwent attempted replant; of the 60 patients who had improperly preserved parts, 23.3% underwent attempted replantation (P = .001). CONCLUSIONS: The majority of patients who suffer traumatic amputations do not present with properly preserved amputated parts, limiting potential replantation. With a direct correlation to attempted replantation, proper preservation is a crucial aspect of care and should not be overlooked when seeking to optimize efforts and results. LEVEL OF EVIDENCE: Level IV.

AP pelvis radiograph is insufficient for diagnosis of U-type sacral fractures.

PURPOSE: We investigated the sensitivity of a screening test for pelvic ring disruption, the AP pelvis radiograph, for clinically serious U-type sacral fractures which merit consultation with an orthopedic trauma specialist and may require transfer to a higher level of care. METHODS: Retrospective clinical cohort of 63 consecutive patients presenting with U-type sacral fractures at one level 1 trauma referral center from January 2006 through December 2019. The sensitivity of the first AP pelvis radiograph obtained on admission, interpreted without reference to antecedent or concomitant pelvis computed tomography (CT) by a radiologist and a panel of three blinded orthopedic traumatologists, was determined against a reference diagnosis made from review of all pelvis radiographs, CT images, operative reports, and clinical documentation. RESULTS: Sensitivity of AP pelvis radiograph for U-type sacral fractures was 2% as interpreted by a radiologist and mean 12% (range 5-27%) as interpreted by orthopedic traumatologists with poor inter-rater agreement (Fleiss' κ = 0.11). 94% of sacra were at obscured by radiographic artifact. CONCLUSION: The sensitivity of an AP pelvis radiograph is poor for U-type sacral fractures, whether interpreted by radiologists or orthopedic traumatologists. Pelvis CT should be considered as a screening test to rule out sacral fracture when the patient reports posterior pelvic pain, even if plain radiography demonstrates no injury or a minimally displaced pelvic ring disruption. LEVEL OF EVIDENCE: Diagnostic level III.

Penetrating abdominal trauma - selected case reports.

We present 3 case-reports with penetrating abdominal injury from our practice in this article. An urgent laparotomy was performed in all cases because of haemodynamic instability or the mechanism of injury. Penetrative abdominal traumas are associated with a high risk of life-threatening intra-abdominal injuries, require urgent revision and are often accompanied by postoperative infections of the peritoneal cavity. In recent years, there has been a growing tendency towards mini-invasive approaches or even non-operative treatment. This trend is particularly evident in the United States of America, where doctors experience a higher number of penetrating injuries compared to the prevalent blunt force trauma in Europe. The authors describe the need to follow all recommended procedures in the pre-hospital and hospital phases of treatment of these patients and compare them with recent literature. Key words: penetrating abdominal trauma.

The rule of two's didn't work: Meckel's diverticulum with hemorrhagic shock in an adolescent.

Meckel's diverticulum classically follows the rule of two's; presenting before the age of two years, found 2 ft. from the ileocecal valve, approximately 2 in. in length, and present in roughly 2% of the population. To our knowledge, there are few cases detailing emergent medicine management of hemorrhagic shock in patients with acute blood loss from a Meckel's diverticulum. We report the case of a 13-year-old male presenting in hemorrhagic shock secondary to an undifferentiated gastrointestinal bleed who was effectively resuscitated in a children's emergency department. Meckel's scan revealed abnormal tracer uptake consistent with Meckel's diverticulum and the patient underwent surgical resection of the diverticulum. This case report details the importance of prompt recognition and appropriate volume resuscitation in a pediatric patient suffering from hemorrhagic shock. Emergency medicine physicians should maintain an index of suspicion for Meckel's diverticulum in any pediatric patient presenting with undifferentiated gastrointestinal hemorrhage.

Association Between Prearrival Notification Time and Advanced Trauma Life Support Protocol Adherence.

BACKGROUND: Prearrival notification of injured patients facilitates preparation of personnel, equipment, and other resources needed for trauma evaluation and treatment. Our purpose was to determine the impact of prearrival notification time on adherence to Advanced Trauma Life Support (ATLS) protocols. MATERIALS AND METHODS: Pediatric trauma activations of admitted patients were analyzed by video review to determine activities performed before and after patient arrival. Using an expert model based on ATLS, fitness scores were calculated that represented model adherence, ranging from "0" (noncompliant) to "100" (completely compliant). Multivariate regression was used to determine the association between fitness values of the evaluation phases and the length of prearrival notification time and injury profiles. RESULTS: Ninety-four patients met study criteria. The average overall fitness was 89.0 ± 7.3, with similar fitness values being observed for the primary and secondary surveys (91.5 ± 13.4 and 88.6 ± 7.7, respectively). Prearrival notification time ranged from 67.3 min before to 4.8 min after patient arrival. Longer prearrival notification time was associated with improved completion of prearrival tasks, overall resuscitation performance, and secondary survey performance. The positive association of overall and secondary survey fitness with notification time was no longer observed when notification time was <5 min and <10 min, respectively. Notification time was correlated with a higher percentage of required team members when the patient arrived (Pearson correlation coefficient 0.46, P < 0.001). CONCLUSIONS: Prearrival notification time has a significant impact on adherence to ATLS protocol. Strategies for improving notification time or improving performance when adequate notification cannot be achieved are needed.

Rubrum Coelis: The Contribution of Real-Time Telementoring in Acute Trauma Scenarios-A Randomized Controlled Trial.

Background: Most deaths in military trauma occur soon after wounding, and demand immediate on scene interventions. Although hemorrhage predominates as the cause of potentially preventable death, airway obstruction and tension pneumothorax are also frequent. First responders caring for casualties in operational settings often have limited clinical experience.Introduction: We hypothesized that communications technologies allowing for real-time communications with a senior medically experienced provider might assist in the efficacy of first responding to catastrophic trauma.Methods: Thirty-three basic life saving (BLS) medics were randomized into two groups: either receiving telementoring support (TMS, n = 17) or no telementoring support (NTMS, n = 16) during the diagnosis and resuscitation of a simulated critical battlefield casualty. In addition to basic life support, all medics were required to perform a procedure needle thoracentesis (not performed by BLS medics in Israel) for the first time. TMS was performed by physicians through an internet link. Performance was assessed during the simulation and later on review of videos.Results: The TMS group was significantly more successful in diagnosing (82.35% vs. 56.25%, p = 0.003) and treating pneumothorax (52.94% vs. 37.5%, p = 0.035). However, needle thoracentesis time was slightly longer for the TMS group versus the NTMS group (1:24 ± 1:00 vs. 0:49 ± 0:21 minu, respectively (p = 0.016). Complete treatment time was 12:56 ± 2:58 min for the TMS group, versus 9:33 ± 3:17 min for the NTMS group (p = 0.003).Conclusions: Remote telementoring of basic life support performed by military medics significantly improved the medics' ability to perform an unfamiliar lifesaving procedure at the cost of prolonging time needed to provide care. Future studies must refine the indications and contraindications for using telemedical support.

Regular, in-situ, team-based training in trauma resuscitation with video debriefing enhances confidence and clinical efficiency.

BACKGROUND: To assess the clinical impact of a regular, multidisciplinary, video debriefed training intervention for trauma team members on real trauma resuscitations. In addition, attending personnel evaluated the training program via questionnaire. METHODS: The training intervention is a regular (monthly), video debriefed, team-based trauma simulation. Training takes place in the fully functional resuscitation bay (in-situ) of the Department of Traumatology at the Klinikum Oldenburg (Level 1, primary teaching hospital for the Carl von Ossietzky University Oldenburg) involving a complete trauma team. Laerdal® Resusci Anne® dummy serves as the patient simulator. A special feature is a structured video debriefing of each participating team to analyse team performance. Data before and after implementation of training was retrospectively analysed. RESULTS: We found a significant decrease in the time from arrival of the patient to computer tomography (CT, Spearman rank coefficient r = - 0.236, p = 0.001). Evaluation of the questionnaire by team members described a significant increase in self-confidence (p < 0.05). CONCLUSION: Monthly video assisted team based in situ training with video debriefing significantly reduces resuscitation time in the emergency bay.

[Parameters influencing the preclinical application of cervical collars]. / Einflussfaktoren auf die präklinische Anlage einer Zervikalstütze.

BACKGROUND: The application of cervical collars is a standard procedure in emergency care of trauma patients. It is often observed that the application of cervical collars is performed incorrectly, which may lead to reduced immobilization of the cervical spine. OBJECTIVES: The objective of this study was to analyze the practical skills of professional emergency care providers concerning the application of cervical collars. MATERIALS AND METHODS: Emergency care professionals (n = 104) were asked to apply a cervical collar to a training doll. Each performance step was assessed separately. Furthermore, personal and occupational data of all study participants were collected using a questionnaire. RESULTS: The study participants included professional rescue personnel and emergency physicians. The average occupational experience of all study participants in out-of-hospital emergency care was 11.1 ± 8.9 years. Most participants had already received training on trauma care (61 %) and felt "very confident" in handling a cervical collar (84 %). The application of the cervical collar was performed correctly in 11 % of the performances. The most common error was incorrect size adjustment of the cervical collar (66 %). No association was found between the correct application of the cervical collar and possible parameters of influence, such as working experience in emergency care or participation in trauma courses. CONCLUSIONS: Despite pronounced subjective confidence regarding the application of cervical collars, this study shows that there are general deficits in the practical skills of applying cervical collars. Therefore, a critical assessment of the current training contents on the subject of trauma care must be demanded.

Comparison between continuous thoracic epidural block and continuous thoracic paravertebral block in the management of thoracic trauma.

BACKGROUND: Postoperative pain is thought to be the single most important factor leading to ineffective ventilation and impaired secretion clearance after thoracic trauma. Effective pain relief can be provided by thoracic epidural analgesia but may have side effects or contraindications. Paravertebral block is an effective alternative method without the side effects of a thoracic epidural. We did this study to compare efficacy of thoracic epidural and paravertebral block in providing analgesia to thoracic trauma patients. METHODS: After ethical clearance, 50 patients who had thoracic trauma were randomized into two groups. One was a thoracic epidural group (25), and second was a paravertebral group (25). Both groups received 10 ml of bolus of plain 0.125% bupivacaine and a continuous infusion of 0.25% bupivacaine at the rate of 0.1 ml/kg/h for 24 h. Assessment of pain, hemodynamic parameters, and spirometric measurements of pulmonary function were done before and after procedure. Visual analog scale (VAS) scores were accepted as main outcome of the study and taken for power analysis. RESULTS: There was significant decrease in postoperative pain in both the groups as measured by VAS score. However, the degree of pain relief between the groups was comparable. There was a significant improvement in pulmonary function tests in both the groups post-procedure. The change in amount of inflammatory markers between both the groups was not significantly different. CONCLUSION: Paravertebral block for analgesia is comparable to thoracic epidural in thoracic trauma patients and is associated with fewer side effects.

Sufficient catheter length for pneumothorax needle decompression: a meta-analysis.

INTRODUCTION: Needle 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. METHODS: A 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. RESULTS: The 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. DISCUSSION: A 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.

Role of pelvic X-ray in blunt trauma patients -- A university hospital experience in Oman.

OBJECTIVE: To confirm the safety of the advanced trauma life support algorithm by comparing the incidence of pelvic fractures diagnosed by pelvic X-ray and computed tomography and to evaluate the need of pelvic X-ray in the management of haemodynamically stable polytrauma patients in whom computed tomography is deemed necessary. METHODS: The prospective study was conducted at Sultan Qaboos University, Muscat, Oman, from January to December 2012, and comprised stable blunt trauma patients treated according to advanced trauma life support guidelines. All the patients underwent pelvic X-ray on presentation and later had computed tomography scan of abdomen and pelvis. Radiology reports were filed by the on-call radiologist prospectively. The reports were reviewed retrospectively. Data was analysed using SPSS 19. RESULTS: Of the 67 patients, 59(88%) were male and 8(12%) were females. The overall mean age was 32.09±12.28 years (range: 14-77 years) Pelvic X-rays showed no fracture in 62(92.5%) cases compared to 55(82.1%) scans. All cases that were positive on pelvic X-ray were detected by scan. Pelvic X-ray revealed only 4(6%) patients as having only pelvic fracture and 1(1.5%) as femoral head fracture. Computed tomography scan was able to detect 6(9%) pelvic fractures, 2(3%) femoral fractures and 4(6%) lumbar fractures. CONCLUSIONS: Computed tomography scan was found to be superior in detecting pelvic, femoral and lumbar fractures.
