Outline of Final Research Achievements

We investigated whether blood gas measurements and lactate values could be affected by the stress of avascularization and hand-shaking during blood sampling. Forty subjects were avascularized in the upper arm, and blood was collected 0, 2, 5, and 10 minutes after avascularization, and blood gas measurements were performed. The results showed no significant increase in pH, PCO2, or lactate values at each avascularization time. When blood gas measurements were performed after a 2-minute hand-shaking session, there were occasional cases where lactate values increased, although no statistically significant differences were observed.
It was found that routine upper arm avascularization does not affect venous blood gases or lactate values. It could not be concluded that the hand-shaking session after avascularization does not affect the values, but it is believed that it will have almost no effect in routine clinical practice.

Academic Significance and Societal Importance of the Research Achievements

駆採血時の駆血や離握手の負荷により、血液ガス測定や乳酸値が変化しうるかを検討した結果、駆血時間や離握手は測定結果に影響を及ぼさないという結果が得られた。
この研究結果により救急外来など日常臨床で頻回に行われる静脈血液ガスや乳酸値の結果は駆血や離握手の影響を受けず信用しうるものであると考えられる。
