Effects of deep saturation diving on blood biochemical indices in divers

Abstract

Objective To explore the effects of deep saturation diving on blood biochemical indices in divers and to analyze the possible causes involved, so as to provide theoretical evidence for the development of medical support profile for the health promotion of divers. Methods Four healthy male divers participated in the 4.9 MPa (480 m) simulated saturation dive. The serum levels of total protein (TP), albumin (ALB), Globulin (GLB), total cholesterol (TC), triglyceride (TG), glucose (Glu), Creatinine (Cr), blood urea nitrogen (BUN), uric acid (UA), immunoglobulin IgA, IgG, IgM, complement C3, C4 were detected by Olympus 2 700 automatic biochemical analyzer. In addition, serum electrolytes potassium (K+ ), sodium (Na+ ), magnesium (Mg2+ ), calcium (Ca2+ ), Iron (Fe3+ ) and chlorine (Cl-) were determined by Toshiba 40FR automatic biochemical analyzer. Results Serum UA level (387.75±35.37) μmol/L of the divers after they came out of the chamber upon completion of the deep saturation dive was obviously lower than that before the entrance into the chamber (482.75 ±75.20) μmol/L (P<0.05). Serum K+ level of the divers (4.00±0.14) mmol /L after they came out of the chamber was markedly lower than that before entrance into the chamber(4.30±0.29)mmol/L (P<0.05). IgA level of the divers after they came out of the chamber (2.36±0.62)g/L was obviously higher than that before entrance into the chamber (1.92±0. 72)g/L(P<0.05), while C3 level of the divers after exposure (1.02±0.11)g/L was lower than that before exposure (1.20±0.26) g/L (P<0.05). Conclusions Deep saturation dive had certain effects on the serum biochemical indices of the divers. Monitoring on the biochemical indices should be enhanced and medical support measures be improved, so as to ensure the health of divers. Key words: Saturation dive; Divers; Blood biochemical indices
