Renaissance of base deficit for the initial assessment of trauma patients: a base deficit-based classification for hypovolemic shock developed on data from 16,305 patients derived from the TraumaRegister DGU®.

Introduction: The recognition and management of hypovolemic shock still remain an important task during initial trauma assessment. Recently, we have questioned the validity of the Advanced Trauma Life Support (ATLS) classification of hypovolemic shock by demonstrating that the suggested combination of heart rate, systolic blood pressure and Glasgow Coma Scale displays substantial deficits in reflecting clinical reality. The aim of this study was to introduce and validate a new classification of hypovolemic shock based upon base deficit (BD) at emergency department (ED) arrival.

Assessment of hypovolaemic shock at scene: is the PHTLS classification of hypovolaemic shock really valid?

Objective: Validation of the classification of hypovolaemic shock suggested by the prehospital trauma life support (PHTLS) in its sixth student course manual.

Methods: Adults, entered into the TraumaRegister DGU(®) database between 2002 and 2011, were classified into reference ranges for heart rate (HR), systolic blood pressure (SBP) and Glasgow coma scale (GCS) according to the PHTLS classification of hypovolaemic shock. First, patients were grouped by a combination of all three parameters (HR, SBP and GCS) as suggested by PHTLS.

Postural control and functional ankle stability in professional and amateur dancers.

Objective: The aim of this study was to compare the postural control and functional ankle stability between professional and amateur dancers as well as controls.

Methods: Thirty professional dancers were compared to thirty amateur dancers and thirty controls. All participants (n=90) completed a questionnaire.

The influence of playing level on functional ankle stability in soccer players.

Objective: The aim of this study was to compare the functional ankle stability between professional and amateur soccer players as well as controls.

Materials And Methods: Thirty professional soccer players, 30 amateur soccer players and 30 controls were evaluated. All participants completed a questionnaire.

The influence of profession on functional ankle stability in musicians.

Objective: The aim of this study was to examine the influence of extensive work-related use of the feet on functional ankle stability among musicians.

Methods: Thirty professional organists were compared to professional pianists and controls. All participants completed a questionnaire.

Influence of age, body mass index and leg dominance on functional ankle stability.

Background: The aim of this study was to examine the influence of age, body mass index (BMI) and leg dominance on the PRT, balance control and foot position sense.

Materials And Methods: The proprioception of the ankle was investigated in 210 participants. All participants completed a questionnaire.

Evaluation of the proprioceptive influence of the cutaneous afferents to the ankle in patients after sural nerve harvesting.

Objective: Cutaneous afferent nerves contribute to joint proprioception. The aim of this study was to retrospectively analyze the proprioceptive influence of the cutaneous afferents to the ankle in patients after sural nerve harvesting in comparison to controls.

Methods: The proprioception of the ankle in 24 patients after sural nerve harvesting was investigated.
