Outline of Final Research Achievements |
It has been reported that initial distribution volume of glucose (IDVG) can be used as an indicator of cardiac preload. I investigated the effects of vasopressors like noradrenaline (NA) on IDVG and the effects of PEEP on IDVG in pigs. It was found that NA significantly increased IDVG and cardiac output (CO) and there was a good correlation between IDVG and CO. It was suggested that IDVG showed the increased cardiac preload introduced by the contraction of capacitance veins with NA. On the other hand, PEEP did not affect IDVG, but significantly decreased CO. IDVG may indicate cardiac preload which reflects stressed volume.

Academic Significance and Societal Importance of the Research Achievements |
ブドウ糖初期分布容量(IDVG)は、中心部細胞外液量(cECF)検査法である。このcECFはStressed Volume(SV)と呼ばれる心臓前負荷と相関関係にあると考えられてきた。また、ノルアドレナリン(NA)という血管収縮薬はSVを増加させることが知られていたが、本研究によってNA投与でIDVGも増加することが判明した。また、IDVGは静脈還流抵抗となるPEEPには影響されないことも判明した。これらのことから、IDVGは敗血症性ショック時にNAなどの昇圧剤投与時やPEEPを用いた人工呼吸管理下においてもSVに関係するcECFの測定法として、有用と考えられた。
