[Emergency room management of multiple trauma : ATLS® and S3 guidelines]

Trauma management in the emergency room is an important part of the treatment chain of the severely injured. Important decisions with respect to diagnostics and treatment must be made under time pressure. Successful trauma management in the emergency room requires a hospital tailored treatment protocol. This written protocol needs consent from all participating disciplines and must be known by all members of the resuscitation team. The ATLS® and the recently published clinical practice guidelines on multiple trauma can be of help in order to establish or update such protocols. In order to continuously evaluate and improve performance in the emergency room local quality circles are needed that truly follow that aim. Important factors are reliability of agreement between the different disciplines and continuous communication of results to the team members. In order to be successful such quality circles need people that care.

The role of early multislice computed tomography in major trauma

Whole-body multislice spiral computed tomography (MSCT) has become a very important dignostic tool in the management of patients with multiple injuries. Many reports exist which demonstrate the feasibility and the benefit when using whole-body MSCT in the early phase of in-hospital management of trauma patients. Even in hemodynamically instable patients (except cardiac arrest), whole-body MSCT can be used and is a safe diagnostic procedure. While the diagnostic superiority of multislice computed tomography is proven for different organ regions (e.g. head/brain, chest, abdomen, pelvis and spine), its use as a single whole-body scan is still part of an ongoing discussion. Especially concerns about radiation exposure are the reason for uncertainty about when using whole-body trauma scan. Predefined scan protocols and individual positioning of patients may help to keep radiation dose as minimal as possible. To justify higher radiation dose, the indication must be chosen appropriately. Therefore, the use of a sensitive and specific triage scheme seems to be reasonable. Overscanning patients with minor trauma needs to be avoided, while the benefit for patients with severe multiple injuries is obvious.

[Emergency room management of severely injured patients]

BACKGROUND

In cases involving major trauma life-threatening situations should be immediately diagnosed and treated. Clinical algorithms can potentially decrease the rate of complications and errors. The purpose of this study was to investigate the incidence of deviations from a multislice computed tomography based trauma room algorithm.

MATERIALS AND METHODS

During a primary trauma survey an independent study monitor observed the on site treatment sequence step by step. Time intervals between admission and start of each procedure were recorded. Deviations from the algorithm and delays were analyzed.

RESULTS

In 57 trauma patients a total of 49 deviations were documented. Median time between admission and transfer to the adjacent MSCT room was 9 min. Of the patients 11 were bypassed to the MSCT suite without a primary survey (19.3%). In 2 cases an absence of non-invasive blood pressure monitoring was recorded (3.5%) and 3 patients with potential cervical spine trauma were not immobilized at the scene or during primary survey (5.3%). In 8 cases focused assessment with sonography for trauma (FAST) was not performed (14%). Contrary to the algorithm 10 patients received an arterial or central venous line during initial treatment (18%) resulting in a median delay of 8 min. The deviations from the algorithm resulted in no adverse effects on complications or mortality.

CONCLUSION

Self-critical analysis of trauma resuscitation can increase the quality of treatment by revealing constantly recurring faults.

Abdominal trauma: from operative to nonoperative management

The nonoperative care of intraabdominal trauma in the polytraumatised patient greatly depends on imaging techniques. The haemodynamically unstable patient should undergo expedient sonography to rule out abdominal haemorrhage. The use of computer tomography (CT) in this difficult patient group is also currently evaluated, however it takes specific amendments to the protocol and institution. In the hemodynamically stable patient however, computer tomography is the modality of choice to evaluate the injured abdomen. Nonoperative treatment can be successful in up to 80% of selected cases. Adjuncts to nonoperative care include embolisation of the spleen and liver in cases of arterial bleeding, and endoscopic retrograde cholangio pancreaticography (ERCP) and stenting for injuries to the biliary tree.

[Polytrauma management in a period of change: time analysis of new strategies for emergency room treatment]

BACKGROUND

Quality management and the early implementation of whole-body multi-slice spiral computed tomography (whole-body MSCT) are becoming increasingly important in the management of patients with multiple trauma. The aim of this study was to evaluate both components with respect to the time factor for treatment.

METHODS

The investigation involved a retrospective data analysis of the time needed in the emergency room for the initial stabilization (phase A), completing the diagnosis (phase B) and the emergency room treatment (phase C). The investigation included three groups: trauma patients imaged in the emergency room with conventional imaging procedures (group I), with whole-body MSCT alone (group II) and those who were imaged with whole-body MSCT after the introduction of a quality management system with standard operating procedures (group III).

RESULTS

The times for resuscitation (phase A), for diagnostic evaluation (phase B) and for total treatment (phase C) were analyzed. The times for phase A were for group I (n=79) 10 min (interquartile range, IQR 8-12 min), group II (n=82) 13 min (IQR 10-17 min) and group III (n=79) 10 min (IQR 8-15 min; p<0.001). The times for phase B were 70 min (IQR 56-85 min) for group I, 23 min (IQR 17-33 min) for group II and 17 min (IQR 13-21 min; p<0.001) for group III. For phase C the times were 82 min (IQR 66-110 min) for group I, 47 min (IQR 37-59 min) for group II and 42 min (IQR 34-52 min; p<0.05) for group III.

CONCLUSION

Quality management and the early implementation of whole-body MSCT can accelerate the treatment work flow. A rapid initial diagnosis represents an important component in the high quality of treatment of polytrauma patients.

[Trauma care management]

Optimal outcome in the treatment of multiple trauma patients requires an initial management fulfilling a high standard of quality assurance. A prerequisite is the availability of adequate resources at all times with respect to personnel, technical equipment, and emergency room design. The aim is-based on standardized and prioritized clinical pathways and algorithms-to identify and treat not only life-threatening and debilitating but all other injuries in a timely fashion. Diagnostic and therapeutic measures to manage airway, breathing, and circulatory problems (including transfusion and surgery for bleeding control) have priority, even over the operative treatment of severe head injuries. With respect to severe intra-abdominal and retroperitoneal injuries, the concept of damage control surgery has reached world wide acceptance. However, many parenchymal lesions of intra-abdominal organs can be managed nonoperatively. Similarly, damage control orthopedics for the initial management of major fractures with initial temporary and minimally invasive fracture stabilization followed by definitive osteosynthesis as soon as the patient has stable organ functions is gaining more acceptance. Maintainance of and improvement in the quality of care requires standardized documentation, regular analysis, and feedback in an internal quality management process as well as participation in an external quality program such as the Trauma Registry of the German Society for Accident Surgery.

[Emergency treatment of thoracic trauma]

Thoracic trauma, most often associated with other serious injuries, is the main cause of death in the first 45 years of life. The percentage of chest injuries in multiple trauma, mainly from blunt impact, has remained relatively constant at 80% during the last 30 years. Isolated thoracic injuries comprise only 25% of all trauma cases, 90% of chest injuries are due to blunt impact, while penetrating injuries make up 5-10%. Since 25% of deaths from trauma are attributable to chest injuries, they determine the survival rate in multiple trauma to a significant extent. The pattern of chest injuries is variable, frequently in different combinations comprising rib cage and diaphragm, lung parenchyma, airway and mediastinal organs. This article details the immediate simultaneous diagnostic and therapeutic procedures in the prehospital phase, management in the emergency room, the relative importance of computed tomography, ultrasound examination and endoscopy in the primary diagnostic evaluation and the principles of anaesthetic management of thoracic trauma.

Introduction of a treatment algorithm can improve the early management of emergency patients in the resuscitation room

INTRODUCTION

Successful management of emergency patients with multiple trauma in the hospital resuscitation room depends on the immediate diagnosis and rapid treatment of the most life-threatening injuries. In order to reduce the time spent in the resuscitation room, an in-hospital algorithm was developed in an interdisciplinary team approach with respect to local structures. The aim of the study was to analyse whether this algorithm affects the interval between hospital admission and the completion of diagnostic procedures and the start of life-saving interventions. Moreover, in-hospital mortality was investigated before and after the algorithm was introduced.

MATERIAL AND METHODS

In this prospective study, all consecutive trauma patients in the resuscitation room were investigated before (group I, 01/04-10/04) and after (group II, 01/05-11/05) introduction of the algorithm. The times between hospital admission and the end of the diagnostic procedures (ultrasound [sono], chest X-ray [CF], and cranial computed tomography [CCT]), and between hospital admission and the start of life-saving interventions were registered and in-hospital mortality analysed.

RESULTS

In the study period, 170 patients in group I and 199 patients in group II were investigated. Injury severity score (ISS) were comparable between the two groups. The intervals between admission and completion of diagnostic procedures were significantly lower after the algorithm was introduced (mean+/-S.D.): sono (11 +/- 10 min versus 7 +/- 6 min, p < 0.05), CF (21 +/- 12 min versus 12 +/- 9 min, p < 0.01), and CCT (55 +/- 27 min versus 32 +/- 14 min, p < 0.01). Moreover, the interval to the start of life-saving interventions was significantly shorter (126 +/- 90 min versus 51 +/- 20 min, p < 0.01). After introducing the algorithm, in-hospital mortality was reduced significantly from 33.3% to 16.7% (p < 0.05) in the most severely injured patients (ISS>or=25).

CONCLUSION

The introduction of an algorithm for early management of emergency patients significantly reduced the time spent in the resuscitation room. The periods to completion of sono, CF, and CCT, respectively, and the start of life-saving interventions were significantly shorter after introduction of the algorithm. Moreover, introduction of the algorithm reduced mortality in the most severely injured patients. Although further investigations are needed to evaluate the effects of the Heidelberg treatment algorithm in terms of outcome and mortality, the time reduction in the resuscitation room seems to be beneficial.
