Bioresorbable sutures: mitundu, nthawi kuchiritsa

Nthawi zina, monga pa opaleshoni, komanso pambuyo pa kubadwa ankafuna imposition wa sutures resorbable. Pakuti nkhaniyi wapadera ntchito. Pali mitundu yosiyanasiyana ya sutures absorbable. Mawu akuti kuchiritsa mabala ngati kumatengera zifukwa zambiri. Choncho sutures monga bioresorbable kupasuka?

The mitundu waukulu stitches

Kuti tiyankhe funso limeneli, m'pofunika kuti anthu amvetse ndi mitundu chachikulu cha mafupa kumeneko. Nthawi zambiri:

1. Internal. seams oterowo superimposed pa choipa chifukwa zimakhudza makina. Pakuti polumikiza minofu pa fupa lothyoka la ntchito yonse ena a zimakhala. Izi sutures bioresorbable kuchiza msanga zokwanira. Iwo inakwaniritsidwa akazi akabereka pa khomo pachibelekeropo. Pankhaniyi, mankhwala oletsa ululu si chofunika, kuyambira gawo ili la kumaliseche wopanda tilinazo.
2. Kunja. Iwonso kuponyedwa ntchito zinthu resorbable. Pambuyo pokamba, kupanga matabwa panthawi yopuma kapena pa kung'ambika kwa perineum, komanso ngati pambuyo opaleshoni. Ngati mugwiritsa ntchito zinthu wamba, izo chofunika kuchotsa kwa masiku 5-7 pambuyo opaleshoni.

Dziwani kuti sutures bioresorbable akhoza kuchiritsa patapita masabata ochepa. Izi zidalira pa zosiyanasiyana zakuthupi ndi kapangidwe kake.

ndi absorbable sutures Kodi

sutures Bioresorbable pafupifupi nthawi zonse alipo. Iwo kawirikawiri ntchito chilonda machiritso zinthu opaleshoni yomwe kugonjetsedwa ndi hydrolysis. Akuti sutures absorbable, amene anataya mphamvu zawo kale pa maola 60. Kutha kwa filaments chifukwa cha kukhudzana:

1. Michere omwe alipo mu zimakhala m'thupi la munthu. M'mawu ena, mapuloteni omwe amalamulira ndi imathandizira zochita mankhwala a.
2. Madzi. mankhwala anachita izi amatchedwa hydrolysis. Mu ulusi adzawonongedwa ndi madzi, amene ali pano mu thupi la munthu.

Kupanga nsugwi polyglycolide ulusi "MedPGA"

Analogs, zinthu opaleshoni ndi "Safil", "Polisorb", "Vicryl".

Bioresorbable sutures pambuyo opaleshoni kapena pambuyo pobereka mwina alipo yarns "MedPGA". Nkhanizi opaleshoni wapangidwa zochokera asidi poligidroksiatsetilovoy. Mu filaments ngati lokutidwa wa polima resorbable. Izi ndi zofunikira kuchepetsa ndi chingwe capillarity, komanso kuchepetsa zotsatira kumaliza chifukwa cha onyamula zinthu kudzera minofu.

Ndi angati watsimikiza ulusi "MedPGA"

sutures Bioresorbable amene anapereka ntchito ulusi "MedPGA" kukumana hydrolytic kudzitsitsa, amene mosamalitsa ankalamulira. Dziwani kuti zinthu ndi mokwanira amphamvu. Patapita masiku 18 yarns kusunga 50% mphamvu katundu.

Complete mayamwidwe zakuthupi opaleshoni kumachitika masiku pokhapokha 60-90. Zimene zimakhala ndi thupi "MedPGA" ulusi ndi negligible.

Dziwani kuti zinthu oterowo opaleshoni chimagwiritsidwa ntchito kutsekedwa kwa zimakhala onse, koma iwo amene ali pansi nkhawa, komanso kwa nthawi yaitali kuchiza. Kawirikawiri "MedPGA" ulusi ntchito mu thoracic ndi m'mimba opaleshoni, matenda achikazi, urology opaleshoni pulasitiki ndipo zamafupa. Komabe, zilibe ntchito kwa zimakhala mantha ndi mtima.

Kupanga nsugwi polyglycolide ulusi "MedPGA-R"

Analogs, zinthu opaleshoni ndi "Safil Quick", "Vicryl Rapid".

"MedPGA-R" - ndi kupanga ulusi anapanga pamaziko a poligliglaktina-910. Chotero opaleshoni resorbable zinthu yokutidwa ndi polima a. Izi ayeziyo pa ndime ya thonje kudzera minofu thupi komanso amachepetsa chingwe ndi capillarity. Kudzera nkhaniyi opaleshoni angagwiritsidwe ntchito sutures bioresorbable.

Ndi angati absorbable suture "MedPGA-R"

"MedPGA-R" - chuma chimene chiri atengeke kuwonongeka hydrolytic. nkhosi Awa silamphamvu. Patapita masiku asanu anapitiriza 50% mphamvu zawo katundu. Complete mayamwidwe kumachitika kokha tsiku 40-50. Dziwani kuti minofu anachita nkhani opaleshoni "MedPGA-P" ndi negligible. Komanso, ulusi musati chifukwa chifuwa.

Agwiritsidwa chuma cha suture wa nembanemba wa mucous, khungu, zofewa minofu, komanso zinthu pamene muyenera yochepa thandizo la pabalapo. Komabe, pali kuchotserapo. yarns amenewa ntchito pa mantha ndi mtima minofu.

Kupanga nsugwi polyglycolide ulusi "MedPGA-910"

Analogues wa zinthu opaleshoni ndi "Safil", "Polisorb", "Vicryl".

"MedPGA-910" ndi suture absorbable Kuzipeka ku poligliglaktina-910. Mabukuwa opaleshoni ali nawo kuchipatala ndi ❖ kuyanika wapadera amene amachepetsa "kumaliza" Zotsatirapo pa ndime ya chuma kudzera minofu, ndi kuchepetsa capillarity ndi chingwe.

Masiku resorption "MedPGA-910"

Choncho pamene odzipereka sutures bioresorbable, "MedPGA-910" superimposed ndi chuma opaleshoni? yarns oterowo mphamvu yapamwamba. Komabe iwo imvera kudzitsitsa hydrolytic. Patapita masiku 18 nkhaniyo opaleshoni angatipulumutse ku 75% mphamvu katundu patapita masiku 21 - 50% patapita masiku 30 - mpaka 25%, ndipo pakutha masiku 70 pali resorption wathunthu wa filaments lapansi.

mankhwala ntchito kutsekedwa kwa zimakhala zofewa womwe si ali mu mavuto, komanso kuti kuchiza msanga, mu pulasitiki, thoracic ndi opaleshoni m'mimba, matenda achikazi, urology ndi zamafupa. Inu simungakhoze ntchito "MedPGA-910" chifukwa suturing mitsempha ndi minofu mtima.

Monononit "PDO"

Analogues, zinthu opaleshoni si kwambiri. Izi "Biosyns" komanso PDS II. filaments amenewa yodziwika ndi mkulu kwachilengedwenso chizindikiro inetrtnosti, nefitilny ndi noncapillary, hydrophobic, kodi sakutaya minofu pa ndime therethrough, ndinapirira, wamphamvu ndithu bwino osokedwa ndi kugwira mfundo.

Ndi angati kutsimikiza monofilament

Monofilament "PDO" atengeke hydrolysis. Chifukwa cha ndondomeko iyi inatulutsa asidi digidroksietoksiuksusnaya, kwathunthu excretes. 2 masabata pambuyo opaleshoni suture zinthu akuzisunga kuti mphamvu 75%. Complete kuvunda amapezeka mkati yarns masiku 180-210.

Pankhani ntchito, ulusi opaleshoni "PDO" ntchito suturing ndi minofu zofewa kugwirizana kwa mtundu uliwonse, kuphatikizapo mtanda yolumikiza thupi mtima mwanayo zimakhala, amene ali mutu kukula zina. Komabe, pali kuchotserapo. Monofilaments sali oyenera suturing minofu, mabala zofuna thandizo kwa milungu 6, komanso iwo amene ali pansi katundu mkulu. Inu simungakhoze ntchito ya suture pamene khazikitsa amadzala, mavavu yokumba mtima, komanso kupanga mtima ziwalo.

Choncho zimene adzakhala absorbable sutures?

Chotsatira, kuyang'ana pa zonse zimene tingachite sutures bioresorbable pambuyo pa kubadwa, pamene odzipereka, ngati kusamalira. Musaiwale kuti zinthu zambiri zimakhudza nthawi ya machiritso chilonda ndi mofulumira wathunthu wa filaments lapansi. Choyamba muyenera kudziwa, kodi chuma chuma opaleshoni. Nthawi zambiri, ulusi anayamba kupasuka masiku 7-14 pambuyo suturing. Kuti athandize kumbali ya ndondomekoyi, pambuyo machiritso a WOPEREKA mabala achotse tinatake tozungulira. Kudziwa nthawi mayamwidwe ulusi ayenera zikhulupiriro ndi dokotala:

1. Kodi stitches anali.
2. Kodi ndi zinthu zinalembedwa thonje.
3. Chitsanzo kuvunda nthawi ya suture lapansi.

Kumapeto kwa

yarns Bioresorbable nthawi zambiri ntchito suturing mabala pa opaleshoni, zomwe zili mu zigawo zakuya minofu, komanso padziko khungu. Mwachitsanzo, mu kuziika ziwalo.

Nkhani yofanana opaleshoni ntchito suturing mabala ndi fractures analandira pobereka. Pankhaniyi, zambiri maphunziro akhala akufufuza. Zotsatira awo anasonyeza kuti suture anapanga asidi polyglycolic, kwathunthu Mwamsanga mu miyezi inayi yokha, ndi chuma pamaziko a polyglactin - atatu. Choncho sutures bioresorbable adzakangamira bala m'mbali isanafike kumaliza machiritso, ndi Kenako amayamba kutha. Ngati ulusi kwa nthawi yaitali adzapulumutsidwa kupulumutsa kusapeza, muyenera kufunafuna thandizo kwa dokotala kapena kupezeka dokotala.
