The Hess test or Rumpel-Leede test is a medical test used to assess capillary fragility. [1] It is also called the Tourniquet test . To perform the test, pressure is applied to the forearm with a blood pressure cuff inflated to between systolic and diastolic blood pressure for 10 minutes.
The test was once part of the World Health Organization (WHO) algorithm for diagnosis of dengue fever, [3] however it is no longer used in the latest WHO guidance. [4] Studies have shown that the tourniquet test has low predictive value for dengue fever and should be used in conjunction with other tests for a reliable diagnosis. [5] [6] [7] [8]
When laboratory tests for dengue fever become positive where day zero is the start of symptoms, 1st refers to in those with a primary infection, and 2nd refers to in those with a secondary infection. [7] Dengue fever may be diagnosed by microbiological laboratory testing. [26]
Other children then became victims to the new symptom. [4] Epidemic dengue has become more common since the 1980s. By the late 1990s, dengue was the most important mosquito-borne disease affecting humans after malaria, with around 40 million cases of dengue fever and several hundred thousand cases of dengue hemorrhagic fever each year ...
A Texas bill would provide training for elementary school children on how to tie tourniquets or pack bleeding wounds during mass-casualty incidents.
Dengue fever is caused by infection through viruses of the family Flaviviridae. The illness is most commonly transmitted by Aedes aegypti mosquitoes in tropical and subtropical regions. [58] Dengue virus has four different serotypes, each of which are antigenically related but have limited cross-immunity to reinfection. [59]
Article says: "The test remains an essential part of the assessment of a patient who may have dengue haemorrhagic fever." Since this is in the context of a statement that a major insurance company has determined that this test is obsolete or unreliable and replaced it by more advanced procedures, we may want to clarify by whom exactly this test is (still) considered essential.
Pressure underneath a tourniquet cuff is not evenly distributed, with the highest pressures localized around the cuff center line and decreasing to zero near the cuff edges. [7] A high rate of change of pressure across the cuff width, or a high cuff pressure gradient, is a leading cause of nerve and muscle injury from tourniquet use. [7]
