Description

The special sepage absorbent dressing of carcinous wound

Technical field

This utility model relates to a kind of medical dressing, and the special sepage absorbent dressing of a kind of carcinous wound, is mainly used in the sepage controlling carcinous wound specifically.

Background technology

Cancerous cell can infiltrate epithelial tissue and lymphatic vessel, blood vessel around, and cause local organization hypoxic-ischemic downright bad, form skin ulcer, namely become carcinous wound (cancer wound), be also called pernicious gill fungus sample wound (malignant fun-gating wound).The metastatic carcinoma patient of 5-10% there will be carcinous wound, wherein 62% occurs in breast carcinoma.Above-mentioned carcinous wound have stench, sepage amount greatly, easy hemorrhage, the large feature of pain, surrounding skin easily damaged five.

When clinical position, carcinous wound is more difficult effective nursing, and its reason is as follows: on the one hand, and the exudate amount of carcinous wound is many and more lasting, if soak clothes and sheet, not only can bring poverty-stricken emotion to patient, also can increase the burden of caretaker; On the other hand; carcinous wound anaerobic infection or neoplasm necrosis produce foul smell usually can permeate the clothes of patient; this makes also usually to be flooded with foul smell in the shelter of patient, so very easily causes the depressive emotion of patient and caretaker, is unfavorable for the daily nursing of carcinous wound.Simultaneously, when nursing carcinous wound, if wound is too dry, wound dressing can with wound surface adhesion, more can cause damage and the pain of granulation tissue during change dressings, more have the possibility causing wound surface hemorrhage at carcinous wound, there are some researches show, dry wound surface more easily infects compared with the wound under wet environment.

At present, in order to the sepage of carcinous wound effectively can be controlled, so that effectively nurse carcinous wound.All the sepage how effectively controlling carcinous wound is studied both at home and abroad, medical supplies clinically for controlling wound exudate have several as follows: wound drainage or application ostomy bag, enclosed type bearing hydrocolloid dressing, alginate dressing, foam dressing, silicone dressing, silver ion dressing, iodine dressing and active carbon dressing, the each tool advantage of above-mentioned medical supplies, but be all difficult to the sepage effectively controlling carcinous wound, be not easy to patient oneself nursing, below the medical supplies of above-mentioned control wound exudate be described:

A. wound drainage or application ostomy bag are one of the methods controlling wound exudate, but have the large and around the skin being grievously injured of wound surface due to carcinous wound, are difficult to daily nursing wound drainage or application ostomy bag being applied to carcinous wound clinically.

B., when wound bed drying or sepage amount are lacked, enclosed type bearing hydrocolloid dressing (Tegasorb of the Comfeel of such as Coloplast, 3M company) can be adopted.Hydrophilic molecules granule is combined on hydrophobic polymer layer and makes by bearing hydrocolloid dressing, and the amount that it can absorb sepage is 30 times from heavy sensation of the body, and its advantage is that hydrophilic layer can absorb wound and ooze out, and hydrophobic layer can stop the pathogen in environment to invade wound.Can fit with wound surface well, the pain that more change dressings causes can be reduced.Therefore bearing hydrocolloid dressing can well wound closure, prevents abnormal flavour from volatilizing.Also just so, this dressing not recommendation, at infected wound, is especially very easily subject in the carcinous wound of anaerobic infection.

C. alginate dressing has been applied in carcinous wound clinically, and it has stronger absorbability, and has the effect of hemostasis, this considerably increases its application in carcinous wound.After wound absorbs sepage, it can form one deck hydrophilic gel on surface, can absorb wound exudate, and maintains the Moist healing environment of wound bed.Because it can stop wound exudate, therefore, it is possible to reduce the foul smell of wound.Alginate thoroughly should remove the residue of adjuvant in use, to reduce the inflammatory reaction of body.This dressing is inviscid, needs to select suitable outer dressing to fix during use.There is dispute in the hemostatic function for alginate, Grocott thinks that the fibre composition of alginate can stimulate fragile wound tissue, increases the weight of wound bleeding.

D. when wound exudate amount is very many, foam dressing can be selected, it can effectively stop that antibacterial enters wound bed, keep the suitable humidity of wound bed, prevention periwound skin humidity infiltrates, but needs before use to determine sepage amount, in order to avoid wound bed liquid is excessively removed, because it can be removed by not damaged, and can absorb a large amount of sepages, many researcheres think that it can be applied to carcinous wound.In addition, from angle attractive in appearance, it is more easily accepted by patient, more smooth and close to the colour of skin of patient because of it.Also there are some researches show that it is limited in the application of carcinous wound, and be not suitable for necrosis or very dirty wound yet, do not fit in some positions of itself and health, as axillary fossa and joint part, this dressing is more suitable for increasing absorbability as two layers of dressing, being applied in of Foam silver dressing is also very common clinically, and these have the high-absorbable dressing of antibacterial activity can reduce the stink of wound and infect sign, but still lacks at present its study and practice in carcinous wound.

E. silicone dressing such as Mei Pikang (Mo Nike) can effectively apply in carcinous wound.This dressing has high-absorbable, non-sticky, alleviates dressing and removes the pain being, Mekrut-Barrows research shows that Mei Pikang can retain 7 days in vivo as first floor dressing, only needs to change outer dressing on time.This dressing is applied rarely found in clinical practice, and its effect in carcinous wound only comes from experimental evidence.

F. silver ion can be attached in DNA and RNA of antibacterial, and makes its degeneration, thus stops copying of antibacterial, and silver ion can also destroy the electron transfer system of antibacterial, and therefore silver ion can reduce bacterial load, thus alleviates stink and wound infection symptom.The curative effect of silver ion dressing in acute and chronic wounds is confirmed by much research, but the research of applying in carcinous wound is also few, some authors can be applied to carcinous wound according to observation suggestion silver ion dressing in clinical practice, and it can reduce wound stink.The product of silver ion dressing is a lot, and wherein the dressing of high-absorbable silver ion is comparatively applicable to carcinous wound.But silver ion dressing costly, the wound needing to carry out antibacterial therapy also can only be used for.

G. the bactericidal mechanism of iodine penetrates microorganism, attacks its protein, nucleotide, fatty acid, and these materials are bases of bacteria live.There are some researches show that its application in wound can alleviate the stink of wound.Iodosorb (Perstorp has different dosage forms as viscose dressing, gel film and paste-like preparation; layer of gel, the moist environment of protection wound can be formed in wound surface when dressing absorbs after sepage, and can bacterial invasion be reduced; this dressing can absorb a large amount of sepages, is therefore applicable to carcinous wound.But Hampton points out that this dressing can make fragile wound more easily hemorrhage, should be prudent when therefore using.

H. there is certain dispute in the application of active carbon in carcinous wound, and some researcheres think that it is applicable to carcinous wound, because it can absorb the material that those easily cause stink, and they is locked in dressing layer.Other scholars think that its inapplicable those needs airtight and that sepage is more wound, because sepage can make carbon lose activity.The active carbon dressing (as: Actisorb Silver220) of the improvement be combined with silver ion, can increase the antibacterial ability of active carbon dressing, and this dressing can not only adsorbs malodorous, and wherein silver ion can kill bacteria.Much research shows this dressing successful in the wound of stench wound and severe sepage, and it can alleviate wound infection and wound stench, reduces the use of antibacterials.
