A new bridge-type fixation structure for umbilical arteriovenous catheterization in neonates

Abstract

The invention relates to the technical field of umbilical arteriovenous catheter fixation, and discloses a novel bridge-type fixation method for newborn umbilical arteriovenous catheterization. The required instruments for the fixation method include: punching forceps, hydrocolloid dressing and scissors. The opening forceps is equipped with a knife mold, one side of the hydrocolloid dressing is provided with a protective paper, and the umbilical arteriovenous catheter has been pre-set at the navel of the newborn. The operation steps of the bridge fixation method are: 1) Equipment preparation, 2) Opening selection, 3) Dressing cutting, 4) Sticking and fixing, 5) Covering the umbilicus; the invention can easily realize the fixation of the umbilical arteriovenous catheter, the operation is simple and convenient, and the expansion of the aseptic operation barrier is realized, and it is beneficial to The cleaning and disinfection of the umbilicus after umbilical artery and vein catheterization can also effectively avoid damage to the skin of newborns, thereby ensuring the effect of umbilical artery and vein catheterization.

Description

technical field [0001] The invention relates to the technical field of umbilical arteriovenous catheter fixation, in particular to a novel bridge-type fixation method for newborn umbilical arteriovenous catheterization which is easy to operate and can be quickly completed. Background technique [0002] In medical treatment, when rescuing critically ill newborns, umbilical artery and umbilical vein cannulation (catheterization) is performed, arterial blood gas or arterial blood pressure is monitored through the umbilical artery, central venous pressure is monitored through the umbilical vein, rescue drugs and repeated blood transfusions are infused, Infusion, etc., are beneficial to the monitoring and treatment of critically ill neonates, and have important clinical significance; Among them, umbilical artery catheterization is mainly suitable for critically ill infants or very low birth weight infants, who need frequent monitoring of arterial blood gas for a long time, shock ...

AI Technical Summary

Problems solved by technology

In this method, because the umbilical cord is used to tie the navel of the patient, a higher bulge is formed at the navel position. After the gauze is covered, the gauze is easy to be lifted up and cannot be flattened on the patient, which is not conducive to the protection of the gauze.

Moreover, covering one side of the gauze can cause the tube to break and affect the patency of the catheter; covering the two sides is not conducive to the disassembly and replacement of the gauze

In addition, the umbilical arteriovenous catheter is simply wound by the umbilical cord, and it is easy to slide and shift after the child's hands and feet are moved or unintentionally pulled during nursing, and the catheter cannot be stabilized, which is not conducive to the treatment of the patient.

[0004] The emergence of the bridge fixation method has improved the stability of the umbilical arteriovenous catheter to a certain extent; specifically, this method is formed by pasting the two sides of the navel of the child with the umbilical arteriovenous catheter with adhesive plasters. Such as the swing arm part of the bridge pier structure, a connecting part is arranged horizontally between the upper ends of the two swing arm parts to form a bridge structure, wherein the connecting part is two relatively bonded adhesive plasters, and the two laterally arranged adhesive plasters are bonded On the umbilical arteriovenous catheter; however, this method is neither waterproof nor easy to irritate the skin; when the adhesive tape is pasted, the adhesive tape is easy to stick to the hands, and it is difficult to operate if wearing gloves, and it is difficult to ensure aseptic operation without wearing gloves; In addition, the navel is relatively humid and easily stained with urine. If ordinary adhesive tape is used, it will easily fall off when soaked, which is not conducive to the fixation of the umbilical arteriovenous catheter, and it is not easy to disinfect. In addition, ordinary adhesive tape is easy to adhere to the skin after a period of use Unlike the catheter, it is difficult to remove. When the adhesive tape needs to be replaced due to contamination, it is easy to damage the skin of the child, and it can cause the catheter to pull, slide and shift, and seriously affect the use of the catheter.
