執行周邊靜脈導管（Peripheral IV）置入時，必須嚴格遵守無菌操作原則。正確的操作順序是為了確保在皮膚消毒後，能迅速完成穿刺，避免消毒後的區域再次受到空氣或操作者手部的污染。止血帶（Tourniquet）的作用是阻斷靜脈回流使血管充盈，以便護理師精確判斷穿刺點，因此必須先扎止血帶，確認血管，再進行無菌消毒與穿刺。
The correct sequence involves applying a tourniquet first to engorge the veins for identification, followed by cleaning the site to maintain sterility, and finally inserting the needle to minimize the time the skin is exposed to potential contamination.
