Data: 2021-11-02
Recently, some nursing colleagues left messages and looked forward to sharing two kinds of messages.tourniquetmethod of use.
Now briefly introduce this method of operation. If you find it useful, please share it with colleagues and interns.
tourniquetOperation method of forearm vein
1. One is tied to the elbow and the other is tied under the wrist. Blue veins can be seen behind the forearm. With the right index finger side touch subcutaneous hidden vein, you can feel the elasticity of the vein.
2. Choose a relatively straight vein for puncture, and consider the direction of catheter fixation after needle insertion and the impact on patient activities. After returning blood, loosen the tourniquet and fix the indwelling needle with a transparent sticker.
WARNING: Sterilize the skin twice with iodophor when disinfecting, e.g. veins are not obvious enough. Apply alcohol cotton or alcohol cotton swab on the vein a few more times, and the vein will be obvious.
Operation method of dorsal vein of hand
This methodtourniquetIt can also be used for venipuncture on the back of the hand. One working clock belt is tied to the wrist joint, and the other is tied to the first joint of 2 to 5 fingers.
But the specific situation requires specific analysis. The patient is of the type with thinner veins and poor circulation. Use twotourniquetThe method of filling the veins is least obvious.
At this time can be combined with non-feeding puncture method. In other words, the nurse uses the left hand to fix the patient's hand on the back palm expansion of the handshake shape, let the patient repeatedly clench his fist, grasp the loose power, and then repeatedly smear with alcohol cotton ball, can also make the back of the hand vein full.
Vascular exposure can fully improve the success rate of one-time puncture, and the study of filling veins mainly revolves around tourniquet and local drug use. The two tourniquets introduced earlier can be pierced. The upper and lower joints of the puncture point or the two tourniquets with a distance of about 15cm from the upper and lower joints of the puncture point can be pierced. Holding the patient's fist, the local blood vessels are full of satisfaction. It is especially suitable for children, patients whose blood vessels are not fixed, cannot be filled, and clenched.
In addition, tourniquet tourniquet tourniquet tourniquet tourniquet tourniquet tourniquet tourniquet tourniquet will make the patient's arm droop. The position of the tourniquet bandage is 10~15cm away from the puncture point, and the relaxation is appropriate. Tourniquet time within 40~120s. When the tourniquet pressure is 10.7 ~ 16.0kPa, the long-distance venous charging reaches a good state.
Reminder: With the development of intravenous infusion tools and the change of the concept of intravenous infusion, the appropriate infusion route (such as CVC, PICC, infusion port, etc.) should be selected according to the patient's condition, treatment plan and vascular conditions.
The tourniquet oppressor nails the tourniquet wrong. If it takes too long, water will be transferred from the blood vessels to the tissue, but the high molecular substances and large particles (cells) cannot be filtered, and the blood will be concentrated.
