Abstract

type:P(論文)

静脈穿刺時に有効な静脈怒張を得るための適切な駆血圧を検討すると共に、静脈怒張度の客観的指標を得ることを目的に、種々の駆血圧における触知静脈怒張度(怒張度)、および静脈断面積等の変化について検討した。対象者は健常成人46名、マンシェットを上腕に装着し、20〜100mmHgで1分間駆血した。駆血圧は順不同とした。駆血後の怒張度は駆血圧80mmHgまでは増加したが、100mmHgではやや減少した。駆血圧60mmHgと80mmHgの間には怒張度に有意な差がみられなかったが、他の駆血圧間では有意な差がみられた。怒張度は圧迫にて静脈が潰れ始める圧力(静脈触知した時の血管抵抗の指標)、静脈拡張比、静脈断面積の順で相関が高く、皮膚表面から静脈までの距離との間にはやや負の相関がみられた。以上より、駆血圧は60mmHgが適切であり、怒張度の客観的指標としては圧迫にて静脈が潰れ始める圧力が最も適切と考えられた。

The purpose of this study was to examine appropriate tourniquet pressure to obtain effective vein distention for venipuncture, and discuss the objective indices for vein distention. Several parameters for vein distention, such as vein cross-section area, were calculated under different tourniquet pressures. Subjects (46healthy adults; 23men, 23women), had a pneumatic tourniquet (width 13cm) applied at the upper arm. and the tourniquet was inflated to 20, 40, 60, 80 or 100mmHg for one minute. The tourniquet pressure was randomized. Venous distention grade by palpation (VDGp) was increased up to 80mmHg of tourniquet pressure, but then slightly decreased at 100mmHg. VDGps for 60 and 80mmHg were not significantly different, but both were significantly higher than that of 20 and 40mmHg. VDGp correlated well with outer pressure, which begins to collapse the vein (index of venous resistance at palpation), the expansion ratio of vein cross-section area before and after tourniquet application, and the vein cross-section area successively.These data suggest that a tourniquet pressure of 60mmHg is appropriate for effective vein distention for venipuncture, and outer pressure, which begins to collapse the vein, is useful for an objective index of vein distention.
