Care of the external exit of the peritoneal dialysis tubing is related to the technical survival rate of peritoneal dialysis patients (in vernacular terms, whether they can still perform peritoneal dialysis), and the incidence of peritonitis is higher in patients with long-term external exit infections than in patients with good external exit production, so care of the external exit of the peritoneal dialysis tubing is very important and must be mastered and strictly followed by every patient and family. The following will be introduced to you one by one the technical essentials of extra-peritoneal dialysis tube outlet care. First, the timing of the external exit care of the abdominal dialysis tube It is recommended that patients with good growth of the external exit routine care twice a week; after bathing, inadvertently pulling the external tube of the abdominal dialysis to carry out an external exit care; in the presence of external exit infection to follow medical advice for appropriate care and treatment. Second, the external exit of the abdominal dialysis tube care techniques 1, let the patient take a flat position, wear a mask; drug change staff wear a mask and hat, remove the hands ornaments, cut short nails, wash hands in accordance with the six-step washing method. 2.Uncover the dressing and adhesive tape, check the situation of secretion on the inner surface of the dressing, squeeze along the tunnel from the direction of the scar at the incision to the outer exit, ask if there is any pain and observe if there is any secretion. Squeeze the canal along the tunnel by lifting it by hand and observe the secretion/cutaneous tissue growth on the inner surface of the outer exit and whether there is granulation. If necessary, use a flashlight and magnifying glass to observe. 3.Wash hands again according to the six-step procedure and prepare nursing utensils: 0.9% sodium chloride injection, 0.5% iodophor, sterile cotton swabs, adhesive tape and dressing. 4.Open the saline, use it once, and discard the remaining directly. 5, with a sterile cotton swab dipped in saline, the left hand to lift the extra-abdominal section of the abdominal dialysis tube, the right hand holding the cotton swab to the exit as the center of the circle from inside to outside circular scrubbing, scrubbing radius of about 1-2cm, at least three times (if there is infection can increase the number of scrubbing until clean). 6. Open the iodophor, mark the date on the iodophor bottle (iodophor should be used for 1 week at most after opening), dip the cotton swab into the appropriate amount of iodophor, preferably 1/3-1/2 of the swab head, do not dip too much to make the iodophor solution drip down, and do not invert the swab. 7. Use the iodine swab to scrub from inside to outside in a circular pattern at a distance of about 2 cm from the outer exit, with a radius of about 5 cm (about the size of a hand), at least three times (if there is an infection, increase the number of scrubs until it is clean). 8. Wait for the saline and iodine to dry naturally, not with a piece of paper or a fan, let alone blowing dry with your mouth. If time is of the essence, dry sterile cotton swabs can be used to dry from the inner to the outer ring. Sterile cotton swabs that have touched the skin of the outer ring cannot be wiped to the inner ring again (the outer exit is the cleanest, gradually the degree of cleanliness decreases outward, repeated wiping will cause secondary contamination). 9.Remove the dressing to ensure that it is within the shelf life, uncover the release paper on the back of the dressing with both hands to avoid touching the sterile area in the center of the dressing, align the outer exit for coverage, and wrap the extended abdominal dialysis tube tightly with the dressing. 10.Follow the natural shape of the catheter and fix it with butterfly tape at about 6CM from the external exit. 11.Put the external short tube into the belt and fix it. Caution 1.Avoid damage to the external outlet, such as excessive pulling of the catheter, frictional pressure at the external outlet, and do not scratch or scrape the external outlet. 2.If scabs appear at the outlet, do not forcibly tear the scabs, use sterile cotton swabs soaked in saline to soften and slowly remove them. 3.The pipeline can be cleaned with saline, avoid using oily cleaners and alcohol preparations in and around the pipeline and external outlet, and avoid using sharp instruments.
