Impact of Advanced Trauma Life Support Training for Improving Mortality Outcome: A Systematic Review and Meta-analysis

Inhalation Injury: Which Providers Can Assess the Need for Intubation?

Previous studies have suggested that many burn patients undergo unnecessary intubation due to concern for inhalation injury. We hypothesized that burn surgeons would intubate burn patients at a lower rate than non-burn acute care surgeons (ACSs). We performed a retrospective cohort study of all patients admitted to an American Burn Association-verified burn center who presented emergently following burn injury from June 2015 to December 2021. Patients excluded include polytrauma patients, isolated friction burns, and patients intubated prior to hospital arrival. Our primary outcome was intubation rates between burn and non-burn ACSs. 388 patients met inclusion criteria. 240 (62%) patients were evaluated by a burn provider and 148 (38%) were evaluated by a non-burn provider; the groups were well-matched. In total, 73 (19%) of patients underwent intubation. There was no difference in the rate of emergent intubation, diagnosis of inhalation injury on bronchoscopy, time to extubation, or incidence of extubation within 48 hours between burn and non-burn ACSs. We found no difference between burn and non-burn ACSs in the airway evaluation and management of burn patients. Surgical providers with acute care surgery backgrounds and Advanced Trauma Life Support training are well-equipped for initial airway management in burn patients. Further studies should seek to compare other types of provider groups to identify opportunities for intervention and education in preventing unnecessary intubations.

Vital signs associated with class I-IV blood loss within 24 hours of birth

The American College of Surgeons Advanced Trauma Life Support (ATLS) training program classifies blood loss in shock classes from I to IV, defined as loss of < 15%, 15-< 30%, 30-< 40%, and 40% of total blood volume. Per ATLS guidelines, shock class is associated with substantial differences in vital signs (Class I vs. IV, heart rate < 100 vs. >140; respiratory rate 14-20 vs. > 35). The degree of vital sign abnormality observed in obstetric patients with blood loss class is not well characterized.

Harnessing power of simulation training effectiveness with Kirkpatrick model in emergency surgical airway procedures

ObjectivesTraining effectiveness indicates how good a program has met pre-set training objectives or organizational goals for the best benefit of healthcare professionals and service users in the community. The study aimed to evaluate training effectiveness following implementation of new training curriculum of emergency surgical airway procedures (Cricothyroidotomy) organized by the Queen Elizabeth Hospital. DesignThis training evaluation relied on observational descriptive study design. Timed task on Cricothyroidotomy procedures and standardized post-training questionnaire were applied to assess the first 3 levels of Kirkpatrick's model: (Level-1) Reaction by training satisfaction; (Level-2) Learning by acquisition of knowledge and skills assessment passing rate; (Level-3) Behavior by personal strengths. SettingThis program was operated in the Multi-Disciplinary Simulation and Skills Centre, a hospital-based high-fidelity simulation training center accredited by the Society for Simulation in Healthcare. ParticipantsThe study recruited 80 trauma service providers, including 35 general surgeons, 15 emergency physicians, 10 anesthesiologists or intensivists, 6 neurosurgeons, 4 orthopedic surgeons, and 10 emergency nurses from five trauma centers under the Hospital Authority. All underwent the Advanced Trauma Life Support training in advance. ResultsCompared with reference score from previous training sessions, the result of program using new training curriculum and simulator demonstrated significant training satisfaction of participants (Level-1), and high level of assertiveness, mental preparedness, self-efficacy, and internal locus of control and responsibility (p < .01, for all in Level-3). All participants (N = 80) completed entire Cricothyroidotomy procedure in 2 min without technical errors (Assessment passing rate = 100%) (Level-2). ConclusionsUnder Kirkpatrick model, simulation training in Cricothyroidotomy procedure using new curriculum and simulators has been proven to be useful for healthcare professionals involved in trauma service management. The result suggests that application of a state-of-the-art training tools to advanced surgical skills training could improve training satisfaction, knowledge and skills acquisition, and personal strengths transferable to clinical practice.

Mixed methods approach to understanding the influence of changes in successive versions of the advanced trauma life support training program on student performance

BackgroundThe Advanced Trauma Life Support course is the American College of Surgeons’ standard of care for physicians who provide initial care to trauma victims. In addition to content updates, Advanced Trauma Life Support version 10 adopted contemporary learning theory and practice into the format and conduct of the training. MethodsThe study used a mixed-methods approach wherein a one-group post-test–only study of student and student refresher exam score differences was followed up with a faculty survey to qualitatively explore the quantitative findings. Mann-Whitney U tests were used to test the null hypotheses that student and student refresher test scores on version 9 (2018) and version 10 (2019) were the same. χ2 tests of independence were conducted to test the null hypotheses that student and student refresher initial assessment pass rates under versions 9 and 10 were the same. Faculty survey responses were analyzed descriptively. ResultsFor the student written tests, the null hypothesis was retained. For the student refresher written tests the null hypothesis was rejected; the 2019 cohort performed worse than the 2018 cohort. Student initial assessment and student refresher initial assessment pass rates in 2018 and 2019 were statistically the same. The majority of faculty reported less motivation for teaching version 10. ConclusionAlthough a quadrennial review of the format and conduct of Advanced Trauma Life Support courses above and beyond content updates is appropriate, it may be prudent to require strong evidence of improved student performance and value before implementing changes to the training.

Advanced Trauma Life Support training. How useful it is?

For more than 20 years, following the changes that took place in Albania in 1992, we receive information from trauma patients in the media about the delivery of trauma services. Police records are worthy of a war balance report. Trauma is estimated to be the cause of deaths in 13.7% / 100,000 people. Every two days three Albanian Citizens die because of Automobile Accidents…&#x0D; Changes have already taken place, but the question arises, who cares about the trauma and its management?&#x0D; Formerly and now the state ... ok ... but? Is this enough?&#x0D; The Ministry of Health should have a “Trauma Committee” if yes… is it active?&#x0D; Already of the three years at the heart of these medical emergency management networks is a National Center of Medical Emergency (NCME).&#x0D; The trauma service delivery is now evolving along the lines of a central and spoken model with a concentration of expertise and specialization in the center surrounded by smaller units that feed on the center.&#x0D; The study showed a 19% increase in the chances of survival since the introduction of these changes.

Review of Different Management Modalities of Penetrating Thoracic and Abdominal Trauma

Abstract Introduction The advanced trauma life support (ATLS) training program was developed to provide uniformity in the assessment and management of trauma patients. Every trauma patient is evaluated using the primary survey; a rapid reproducible physical exam designed to diagnose those conditions that are immediately life-threatening first. The primary survey consists of the sequential assessment and treatment of airway, breathing, circulation, disability and exposure/environment, represented by the mnemonic (A.B.C.D.E) Objectives To review the different management strategies of penetrating abdominal and thoracic trauma. Data Sources Medline databases (PubMed, Medscape, ScienceDirect. EMF-Portal) and all materials available in the Internet till 2018. Conclusions In summation, most patients with PAT, especially gunshot wounds, still require surgery. On initial survey, patients who are hemodynamically unstable, have diffuse abdominal pain; evisceration, or peritoneal findings must go to the operating room. Patients with an altered sensorium, head injury, inability to cooperate with serial abdominal exams, or patients who will be undergoing an operative procedure somewhere other than the abdomen may be explored as well, depending on the comfort level of the trauma surgeon. This leaves a clinical subset that can be managed non operatively. In these patients, SNOM can drastically reduce the rates of negative and nontherapeutic laparotomies and result in a cost savings and safety benefit to the patient.

Cost Analysis of the Mongolian ATLS© Program: A Framework for Low- and Middle-Income Countries.

Trauma is the leading cause of death among Mongolians aged 24-44. To improve initial management of injured patients, the Mongolian National University of Medical Sciences (MNUMS) implemented the American College of Surgeons' (ACS) Advanced Trauma Life Support (ATLS) training program in 2015. Cost analysis demonstrates that such programs can have clear pathways to self-sufficiency. Costs associated with an ACS Mongolian ATLS program were quantified based on discussions with the Mongolian government, MNUMS, ATLS Australasia headquarters, and existing pricing data. Costs were then classified as either essential or contingencies. These classifications determined budgetary items for each program. Savings projections for contingencies included training Mongolian instructors and educators. Scenarios for funding the budget were then assessed. The minimum annual cost of ATLS in Mongolia, which includes 3 ATLS student courses/1 instructor course, is $10,709. A budget of $19,900 includes additional contingencies. The scenario that involves foreign instructors is the most expensive one. An initial investment of $85,000 to train Mongolian instructors reduces annual costs by $48,305 (71% reduction). An investment of $4050 to train a Mongolian educator will reduce costs by $1750 annually. ATLS can be sustained with 0.04% of Mongolia's current spending on public health and preventative services. Initial investment to train Mongolian ATLS instructors leads to substantial savings. Training a Mongolian educator lowers long-term costs. When minimum costs for ATLS courses are understood, these can be scaled up and supported with different contingencies and minimal funding by government or third-party stakeholders.

Global Collaboration to Modernize Advanced Trauma Life Support Training

Each year, thousands of surgeons and other trauma health care providers participate in the American College of Surgeon's Advanced Trauma Life Support (ATLS) program, which historically has allowed trainees to practice cricothyroidotomy, chest tube insertion, pericardiocentesis, venous cutdown, and diagnostic peritoneal lavage on live dogs, pigs, sheep, and goats. However, more than 99% of ATLS programs in the United States and Canada have now ended animal use, driven primarily by simulation technology advancements. This review details an international survey of animal versus simulation use in ATLS programs and summarizes the surgical training impact of a novel collaboration between the industry manufacturer of the TraumaMan human simulator, Simulab Corporation (Seattle, Washington), and an animal protection nongovernmental organization (NGO) based in Norfolk, Virginia, to replace animal use in ATLS programs with human simulators. From 2012 through 2017, the NGO e-mailed formal surveys concerning program statistics and animal use practices to ATLS officials in various countries (N = 64). The survey response rate was 87.5% and included pre- and post-comparison surveys relative to the industry-NGO simulation collaboration. Eighteen ATLS programs (32.1%) initially replied that they use nonanimal training methods, whereas 38 ATLS programs (67.8%) replied that they use animals for surgical skills training and cited financial constraints as the primary barrier to adopting human simulation methods. Through the industry-NGO collaboration, the NGO donated 119 TraumaMan models valued at nearly $3 million (USD) to ATLS programs in 22 countries, such that 75% of those ATLS programs surveyed by the NGO now use exclusively nonanimal simulation models. The industry-NGO collaboration successfully transformed the surgical skills laboratories of 22 international ATLS programs to replace animal use with nonanimal simulation models that are more anatomically realistic, cost less, and allow trainees to repeat surgical skills until proficiency.

Tachycardic and non-tachycardic responses in trauma patients with haemorrhagic injuries

BackgroundAnalyses of large databases have demonstrated that the association between heart rate (HR) and blood loss is weaker than what is taught by Advanced Trauma Life Support training. However, those studies had limited ability to generate a more descriptive paradigm, because they only examined a single HR value per patient. MethodsIn a comparative, retrospective analysis, we studied the temporal characteristics of HR through time in adult trauma patients with haemorrhage, based on documented injuries and transfusion of ≥3 units of red blood cells (RBCs). We analysed archived vital-sign data of up to 60 min during either pre-hospital or emergency department care. ResultsWe identified 133 trauma patients who met the inclusion criteria for major haemorrhage and 1640 control patients without haemorrhage. There were 55 haemorrhage patients with a normal median HR and 78 with tachycardia. Median ΔHR was −0.8 and +0.7 bpm per 10 min, respectively. Median time to documented hypotension was 8 and 5 min, respectively. RBCs were not significantly different; median volumes were 6 (IQR: 4–13) and 10 units (IQR: 5–16), respectively. Time-to-hypotension and mortality were not significantly different. Tachycardic patients were significantly younger (P < 0.05). Only 10 patients with normal HR developed transient/temporary tachycardia, and only 11 tachycardic patients developed a transient/temporary normal HR. ConclusionsThe current analysis suggests that some trauma patients with haemorrhage are continuously tachycardic while others have a normal HR. For both cohorts, hypotension typically develops within 30 min, without any consistent temporal increases or trends in HR.

Effect of training in advanced trauma life support on the kinematics of the spine: A simulation study.

More than 7.5 million people in the world are affected by spinal cord injury (SCI). In this study, we aimed to analyze the effect of training in advanced trauma life support (ATLS) on the kinematics of the spine when performing different mobilization and immobilization techniques on patients with suspected SCI. A quasi-experimental study, clinical simulation, was carried out to determine the effect of training in ATLS on 32 students enrolled in the Master's program of Emergency and Special Care Nursing. The evaluation was performed through 2 maneuvers: placing of the scoop stretcher (SS) and spinal board (SB), with an actor who simulated a clinical situation of suspected spinal injury. The misalignment of the spine was measured with the use of a Vicon 3D motion capture system, before (pre-test) and after (post-test) the training. In the overall misalignment of both maneuvers, statistically significant differences were found between the pre-test misalignment of 62.1° ± 25.9°, and the post-test misalignment of 32.3° ± 10.0°, with a difference between means of 29.7° [(95% confidence interval, 95% CI 22.8–36.6°), (P = .001)]. The results obtained for the placing of the SS showed that there was a pre-test misalignment of 65.1° ± 28.7°, and a post-test misalignment of 33.2° ± 10.1°, with a difference of means of 33.9° [(95% CI, 23.1–44.6°), (P = .001)]. During the placing of the SB, a pre-test misalignment of 59.0° ± 28.7° and a post-test misalignment of 33.4° ± 10.0° were obtained, as well as a difference of means of 25.6° [(95% CI 16.6–34.6°), (P = .001)]. The main conclusion of this study is that training in ATLS decreases the misalignment provoked during the utilization of the SS and SB, regardless of the device used.

The correlation between ATLS and junior doctors’ anatomical knowledge of central venous catheter insertion at a major trauma centre in South Africa

ObjectiveTo review the ability of junior doctors (JDs) in identifying the correct anatomical site for central venous catheterization (CVC) and whether prior Advanced Trauma Life Support (ATLS) training influences this. DesignWe performed a prospective, observational study using a structured survey and asked a group of JDs (postgraduate year 1 [PGY1] or year 2 [PGY2]) to indicate on a photograph the exact site for CVC insertion via the internal jugular (IJV) and the subclavian (SCV) approach.This study was conducted in a large metropolitan university hospital in South Africa. ResultsA total of 139 JDs were included. Forty-four per cent (61/139) were males and the mean age was 25 years. There were 90 PGY1s (65%) and 49 PGY2s (35%). Overall, 32% (45/139) were able to identify the correct insertion site for the IJV approach and 60% (84/139) for the SCV approach. Of the 90 PGY1s, 34% (31/90) correctly identified the insertion site for the IJV approach and 59% (53/90) for the SCV approach. Of the 49 PGY2s, 29% (14/49) correctly identified the insertion site for the IJV approach and 63% (31/49) for the SCV approach. No significant difference between PGY1 and 2 were identified. Those with ATLS provider training were significantly more likely to identify the correct site for the IJV approaches [OR=4.3, p=0.001]. This was marginally statistically significant (i.e. p>0.05 but <0.1) for the SCV approach. ConclusionsThe majority of JDs do not have sufficient anatomical knowledge to identify the correct insertion site CVCs. Those who had undergone ATLS training were more likely to be able to identify the correct insertion site.

Effect of team training on efficiency of trauma care in a Chinese hospital.

ObjectiveMultidisciplinary trauma teams are the standard of care in the USA, but staffing differences and lack of advanced trauma life support training hinder replication of this system in Chinese hospitals. We investigated the effect of simulation team training on initial trauma care.MethodsOver 15 months, we compared grade I trauma patients cared for by the trained team and those cared for using traditional practice on times from emergency room arrival to tests/procedures. Propensity-score analysis was performed to improve between-group comparisons.ResultsDuring the study, 144 grade I trauma patients were treated. Trained team patients showed shorter times from emergency room arrival to initiation of hemostasis (31.0 [13.5–58.5] vs. 113.5 [77–150.50] min), blood routine report (8 [5–10.25] vs. 13 [10–21] min), other blood tests (21 [14.75–25.75] vs. 31 [25–37] min), computed tomography scan (29.5 [20.25–65] vs. 58.5 [30.25–71.25] min) and tranexamic acid administration (31 [13–65] vs. 90 [65–200] min). Similar results were obtained for the propensity-score matched cohort.ConclusionSimulation team training could help reduce time to blood routine reports, scans and hemostasis. Assessment of available resources and development of targeted team training could improve care in resource-limited hospitals.

Performance in Trauma Resuscitation at an Urban Tertiary Level I Pediatric Trauma Center.

The role of the surveyor in trauma resuscitations is to identify life-threatening injuries and is meant to be conducted by a set protocol for every patient. Optimal performance of the trauma survey is known to be a challenge in pediatric trauma resuscitation. A postulated reason for this observation is that many trainees, such as pediatric residents, who perform the trauma survey have minimal experience and do not have formal advanced trauma life support training. The assessment of factors that may be obstacles in performing the trauma survey has not been studied robustly. The objective of this retrospective cohort study was to use video review of resuscitation of real-life traumatically injured children to (1) describe the characteristics of the trauma patient, the surveyor, and the trauma response team in its current state of function at a tertiary level I trauma center, (2) describe current performance of primary and secondary surveys, as measured by an assessment tool, and (3) determine whether there are specific characteristics associated with reduced quality, completeness, or timeliness of the assessment of an injured child. Retrospective review of emergency department (ED) trauma activations captured by video recording between June 2009 and January 2012. Video-recorded resuscitations were reviewed, and survey performance was scored using a novel assessment tool applying a scoring system (0, 1, or 2 points) for each essential element (airway, breathing, circulation, etc.) accounting for quality, sequence, and timing of assessments. Maximum score was 8 points for the primary survey and 22 points for the secondary survey. Time to completion of survey elements was recorded. Chart review identified surveyor characteristics (level of training and type of training program) and patient data fields (age, mechanism of injury, trauma level, Glasgow Coma Score, time of encounter, disposition, and number of procedures). Descriptive statistics and univariate analysis were performed. Of 749 eligible trauma activations, 228 activations were enrolled in the study with complete data for 202 patients. Most activations met level II criteria and involved blunt trauma. Most patients had a Glasgow Coma Score of 15 and were non-ICU inpatient admissions. PGY-3 residents performed the most surveys (53% of surveys done by residents). Pediatric residents performed 46% of surveys; emergency medicine (EM) residents, 41%; and pediatric EM fellows, 6%. Median scores on primary and secondary surveys were 7 and 12, respectively; median time to completion was 82 seconds and 265 seconds, respectively. Only 22% of primary surveys and 0% of secondary surveys were performed completely. Pediatric EM fellows had the highest mean score on primary and secondary survey. Pediatric EM fellows took longest to perform primary survey and shortest to complete secondary survey. Mean scores on primary and secondary survey were not significantly different between pediatric and EM residents (6.7 vs 6.7; 12.5 vs 11.6). There was no association between survey scores and level or type of training. Emergency medicine residents spent less time on the trauma survey, but this difference did not reach statistical significance. Primary and secondary surveys are frequently performed incompletely and inefficiently regardless of level of training or type of training program. There is no difference in measured performance among different types of residency programs. The impact of trauma resuscitation education on improved survey performance should be studied prospectively.

The Academy of Trauma Surgery (AUC). Service provider and management organization of the DGU

At the beginning of this century the German Trauma Society (DGU) became extensively active with an initiative on quality promotion, development of quality assurance and transparency regarding treatment of the severely injured. A white book on "Medical care of the severely injured" was published, focusing on the requirements on structural quality and especially procedural quality. The impact of the white book was immense and a trauma network with approved trauma centers, structured and graded for their individual trauma care performance, was developed. In order to monitor and document the required quality of care, a registry was needed. Furthermore, for cooperation within the trauma networks innovative methods for digital transfer of radiological images and patient documents became necessary. Finally, the auditing criteria for trauma centers had and still have to be completed with advanced medical education and training programs. In order to realize the implementation of such a broad spectrum of economically relevant and increasingly complex activities the Academy of Trauma Surgery (AUC) was established as a subsidiary of the DGU in 2004. The AUC currently has four divisions: 1) networks and health care structures, 2) registries and research management, 3) telemedicine, 4) medical education and training, all of which serve the goal of the initiative. The AUC is a full service provider and management organization in compliance with the statutes of the DGU. According to these statutes the business operations of the AUC also cover projects for numerous groups of patients, projects for the joint society the German Society for Orthopedics and Trauma (DGOU) as well as other medical institutions. This article describes the success stories of the trauma network (TraumaNetzwerk DGU®), the TraumaRegister DGU®, the telecooperation platform TKmed®, the new and fast-growing orthogeriatric center initiative (AltersTraumaZentrum DGU®) and the division of medical education and training, e.g. advanced trauma life support (ATLS®) and other training programs including the innovative interpersonal competence (IC) course.

Advanced trauma life support training: How useful it is?

We have tried in a recently published systematic review (World J of Surg 2014; 38: 322-329) to study the educational value of advanced trauma life support (ATLS) courses and whether they improve survival of multiple trauma patients. This Frontier article summarizes what we have learned and reflects on future perspectives in this important area. Our recently published systematic review has shown that ATLS training is very useful from an educational point view. It significantly increased knowledge, and improved practical skills and the critical decision making process in managing multiple trauma patients. These positive changes were evident in a wide range of learners including undergraduate medical students and postgraduate residents from different subspecialties. In contrast, clear evidence that ATLS training reduces trauma death is lacking. It is obvious that it is almost impossible to perform randomized controlled trials to study the effect of ATLS courses on trauma mortality. Studying factors predicting trauma mortality is a very complex issue. Accordingly, trauma mortality does not depend solely on ATLS training but on other important factors, like presence of well-developed trauma systems including advanced pre-hospital care. We think that the way to answer whether ATLS training improves survival is to perform large prospective cohort studies of high quality data and use advanced statistical modelling.

Mental practice: a simple tool to enhance team-based trauma resuscitation.

Effective trauma resuscitation requires the coordinated efforts of an interdisciplinary team. Mental practice (MP) is defined as the mental rehearsal of activity in the absence of gross muscular movements and has been demonstrated to enhance acquiring technical and procedural skills. The role of MP to promote nontechnical, team-based skills for trauma has yet to be investigated. We randomized anaesthesiology, emergency medicine, and surgery residents to two-member teams randomly assigned to either an MP or control group. The MP group engaged in 20 minutes of MP, and the control group received 20 minutes of Advanced Trauma Life Support (ATLS) training. All teams then participated in a high-fidelity simulated adult trauma resuscitation and received debriefing on communication, leadership, and teamwork. Two blinded raters independently scored video recordings of the simulated resuscitations using the Mayo High Performance Teamwork Scale (MHPTS), a validated team-based behavioural rating scale. The Mann-Whitney U-test was used to assess for between-group differences. Seventy-eight residents provided informed written consent and were recruited. The MP group outperformed the control group with significant effect on teamwork behaviour as assessed using the MHPTS: r=0.67, p<0.01. MP leads to improvement in team-based skills compared to traditional simulation-based trauma instruction. We feel that MP may be a useful and inexpensive tool for improving nontechnical skills instruction effectiveness for team-based trauma care.

Correlation Between ATLS Training and Junior Doctors’ Anatomical Knowledge of Intercostal Chest Drain Insertion

To review the ability of junior doctors (JDs) in identifying the correct anatomical site for intercostal chest drain insertion and whether prior Advanced Trauma Life Support (ATLS) training influences this. We performed a prospective, observational study using a structured survey and asked a group of JDs (postgraduate year 1 [PGY1] or year 2 [PGY2]) to indicate on a photograph the exact preferred site for intercostal chest drain insertion. This study was conducted in a large metropolitan university hospital in South Africa. A total of 152 JDs participated in the study. Among them, 63 (41%) were men, and the mean age was 24 years. There were 90 (59%) PGY1 doctors and 62 (41%) PGY2 doctors. Overall, 28% (42/152) of all JDs correctly identified the site that was located within the accepted safe triangle. A significantly higher proportion of PGY2 doctors selected the correct site when compared with PGY1 doctors (39% vs 20%, p = 0.026). Those who had prior ATLS provider training were 6.8 times more likely to be able to identify the correct site (RR = 6.8, 95% CI: 3.7-12.5). Most of the JDs do not have sufficient anatomical knowledge to identify the safe insertion site for intercostal chest drain. Those who had undergone ATLS training were more likely to be able to identify the safe insertion site.

Delaying urinary catheter insertion in the reception and resuscitation of blunt multitrauma and using a full bladder to tamponade pelvic bleeding

This article proposes a counter-argument to standard Advanced Trauma Life Support (ATLS) training – which advocates bladder catheterisation to be performed as an adjunct to the primary survey and resuscitation for early decompression of the bladder and urine output monitoring. We argue the case for delaying bladder catheterisation until after definitive truncal Computed Tomography (CT) imaging.To reduce pelvic volume and associated bleeding, our trauma team delay catheter insertion until after the initial CT scan. The benefits of a full bladder also include improved views on initial Focussed Assessment with Sonography in Trauma (FAST) scan and improved interpretation of injuries on CT. Our urinary catheter related infection rates anecdotally decreased when insertion was delayed and consequently performed in a more controlled, non-resuscitation setting following CT.Adult blunt multitrauma patients with pelvic ring fractures are at risk of significant haemorrhage. Venous, arterial and medullary injuries with associated bleeding may be potentiated by an increased pelvic volume with ring disruption, as well as a reduced pressure effect from retroperitoneal and intra-pelvic organs on bleeding sites. Various techniques are used to reduce intra-pelvic bleeding.For shocked patients who have sustained major pelvic injuries with no other signs of urinary tract trauma and minimal urine in the bladder on initial FAST scan, we advocate careful, aseptic Foley catheter insertion followed by bladder insufflation with 500–600mL of Normal Saline (NS) and subsequent catheter clamping to tamponade pelvic bleeding.
