Deep diving causes significant decreases in platelet counts, with recovery upon surfacing. Ethylenediaminetetraacetic acid is a suitable anticoagulant for divers, unlike sodium citrate.

Area of Science:

  • Marine Biology
  • Physiology
  • Biochemistry

Background:

  • Deep diving presents physiological challenges.
  • Understanding blood parameter changes in divers is crucial for safety.
  • Previous research on platelet behavior during extreme pressure exposure is limited.

Purpose of the Study:

  • To investigate the impact of deep diving on platelet counts.
  • To evaluate the efficacy of different anticoagulants for blood samples from divers.
  • To assess the effect of inert gas removal on platelet counts in deep-sea samples.

Main Methods:

  • Blood samples were collected from 10 divers during experimental deep dives (450m and 600m).
  • Platelet counts and hematocrit were measured using different anticoagulants (sodium citrate, ethylenediaminetetraacetic acid).

  • Fluorocarbon was tested for inert gas removal before sample decompression.

    • Main Results:

    • Sodium citrate caused artifactual thrombocytopenia; ethylenediaminetetraacetic acid was satisfactory.
    • Mean platelet count decreased significantly from 272,600/mm³ at 450m to 177,700/mm³ at 360m, recovering to 209,900/mm³ at surfacing.
    • Mean hematocrit increased from 44.7% predive to 59.4% at 450m, returning to 40.9% at surfacing.
    • Fluorocarbon degassing did not affect platelet counts.

    Conclusions:

    • Deep diving significantly alters platelet counts and hematocrit in divers.
    • Ethylenediaminetetraacetic acid is recommended for anticoagulant use in diving research.
    • Fluorocarbon degassing is not necessary for accurate platelet count analysis in decompressed samples.
