Lub sijhawm tus kws phais neeg sawv cev rau tus neeg mob kom kaw qhov kev txiav, qhov kev txiav txim siab tseem ceeb tshwm sim hauv qhov sib cais thib ob. Nws tsis yog hais txog kev kaw qhov sib txawv xwb; nws yog hais txog kev xaiv cov cuab yeej zoo tshaj plaws los xyuas kom lub cev kho kom raug. Txawm hais tias cov ntsiab lus feem ntau raug cuam tshuam los ntawm kev sib tham, rau cov kws kho mob thiab cov neeg saib xyuas kev yuav khoom, qhov sib txawv yog qhov tseem ceeb. Peb tab tom tham txog lub phais suture. Cov khoom siv me me no yog qhov tsis zoo ntawm chav ua haujlwm. Seb nws yog ib qho kev phais mob plab sib sib zog nqus los yog kho kom zoo nkauj me me rau ntawm lub ntsej muag, lub suture tuav tus yuam sij rov qab. To taub cov hom suture, tus cov ntaub ntawv suture, thiab seb yuav siv lub absorbable los yog tsis-absorbable kev xaiv yog qhov tseem ceeb rau kev ua tiav qhov txhab kaw.
Dab tsi yog qhov txawv ntawm Suture thiab Stitch?
Nws yog ib txwm hnov cov neeg mob nug, “Puas muaj pes tsawg xaws kuv puas tau?” Txawm li cas los xij, hauv ntiaj teb kev kho mob, qhov tseeb yog txhua yam. Nws muaj qhov sib txawv ntawm a suture thiab a xawsCov. Tus suture yog lub cev tiag tiag khoom siv- xov nws tus kheej. Nws yog tus khoom siv kho mob siv kho qhov raug mob. Ntawm qhov tod tes, lub xaws yog cov txheej txheem los yog lub voj tshwj xeeb ua los ntawm tus kws phais los tuav lub nqaij ua ke.
Xav txog nws zoo li xaws. Cov suture yog tus xov thiab koob, thaum lub xaws yog lub voj uas koj pom ntawm daim ntaub. A tus kws phais plab siv a suture los tsim a xaws. Thaum lub tsev kho mob xaj khoom, lawv tab tom yuav sutures, tsis xaws. Kev nkag siab txog cov ntsiab lus no pab xaiv qhov raug cov ntaub ntawv suture Rau qhov tshwj xeeb phais qhov chaw. Seb lub hom phiaj yog mus tshem tawm stitches tom qab los yog cia lawv yaj, cov txheej txheem ib txwm pib nrog cov khoom zoo suture nws tus kheej.
Kev tshuaj xyuas tus qauv: Monofilament vs. Braided Suture
Thaum koj saib ze ntawm a suture, koj yuav pom nws cov kev tsim kho txawv. Qhov no tsis yog xwm txheej; tus qauv dictates li cas tus suture kov thiab cuam tshuam nrog nqaijCov. Ib monofilament suture yog ua los ntawm ib ib txoj hlua ntawm cov khoom. Piv txwv suav nrog nylon, polyprropylene, thiab polydioxanone tshuaj (PDS). Lub ntsiab kom zoo dua ntawm a monofilament qauv yog tias nws yog du. Nws hla dhau nqaij nrog me ntsis luag, uas txo cov ntaub so ntswg thiab raug mob. Vim hais tias nws yog ib qho yooj yim strand, nws tsis muaj crevices rau harbor cov kab mob, ho txo tus nqi. Kev pheej hmoo kis tau.
Piv txwv li, a braided suture (lossis multifilament sutures) yog tsim los ntawm ob peb txoj hlua me me braided ua ke, zoo li ib txoj hlua me me. Silk suture thiab Vicryl yog ib qho piv txwv. Cov braid ua cov suture hloov tau ntau dua thiab yooj yim tuav Rau tus kws phais plab. Nws tsim kev sib txhuam zoo heev, uas txhais tau tias nws muaj zoo knot kev ruaj ntseg-Tus knot nyob ruaj khov. Txawm li cas los xij, lub braid tuaj yeem ua tau zoo li lub wick, muaj peev xwm nqus cov kua thiab cov kab mob mus rau hauv lub qhov txhab, uas yog vim li cas monofilament feem ntau nyiam rau cov kab mob uas muaj kab mob. Qhov kev xaiv ntawm monofilament thiab a braided suture feem ntau los mus rau kev sib pauv ntawm kev yooj yim thiab kev pheej hmoo kis mob.
Kev faib loj: Absorbable vs. Non-absorbable Sutures
Tej zaum qhov tseem ceeb tshaj plaws kev faib tawm hauv suture hom yog seb lub cev puas yuav tawg. Absorbable sutures yog tsim los rhuav tshem hauv lub cev lub sijhawm. Lawv feem ntau yog siv sab hauv rau cov ntaub so ntswg kho qhov twg koj tsis tuaj yeem rov qab mus rau hauv kom tshem tawm lawv. Cov ntaub ntawv zoo li catgut (natural material) los yog hluavtaws poliglecaprone thiab polydioxanone tshuaj yog tsim los rau degrade ntawm hydrolysis los yog enzymatic digestion. Cov no yog cov neeg mob feem ntau hu dissolvable stitches.
Hloov pauv, tsis-absorbable sutures nyob twj ywm nyob rau hauv lub cev mus tas li los yog kom txog thaum lawv tawm ntawm lub cev. Nylon, polyprropylene, thiab txhob lo lo ntxhuav suture poob rau hauv qeb no. Tsis-absorbable sutures feem ntau yog siv rau daim tawv nqaij kaw qhov twg suture tuaj yeem raug tshem tawm thaum lub qhov txhab kho, lossis rau cov ntaub so ntswg uas xav tau kev txhawb nqa mus ntev, xws li hauv mob plawv phais los yog leeg kho. Cov suture ua raws li kev txhawb nqa mus tas li. Xaiv ntawm absorbable thiab tsis-absorbable sutures nyob ntawm tag nrho cov qhov chaw ntawm qhov txhab thiab ntev npaum li cas nqaij xav tau kev txhawb nqa kom rov muaj zog.
Sib sib zog nqus dhia mus rau hauv Natural thiab Synthetic Suture Materials
Keeb kwm ntawm lub suture yog fascinating, evolving los ntawm ntuj fibers mus rau advanced polymers. Sutures yog ua los ntawm ib qho natural thiab hluavtaws qhov chaw. Ntuj cov ntaub ntawv suture suav nrog txhob lo lo ntxhuav, linen, thiab catgut (muab los ntawm submucosa ntawm yaj los yog nqaij nyug hnyuv, nplua nuj nyob rau hauv collagen). Thaum catgut yog tus qauv rau ntau pua xyoo, cov ntaub ntawv ntuj feem ntau provoke siab dua cov ntaub so ntswg vim lub cev lees paub lawv li cov proteins txawv teb chaws.
Hnub no, cov khoom siv hluavtaws yog dav nyiam. Synthetic sutures, xws li nylon, polyester, thiab polypropylene sutures, yog engineered rau kev kwv yees. Lawv ua rau tsawg heev cov ntaub so ntswg thiab muaj qhov nqus tau zoo ib yam lossis lub zog ruaj khov. Synthetic kev xaiv zoo li poliglecaprone muab siab pib tensile zog thiab hla dhau nqaij yooj yim. Thaum a tus kws phais plab tej zaum tseem siv tau txhob lo lo ntxhuav suture rau nws txoj kev tuav zoo heev thiab knot kev ruaj ntseg, qhov sib txawv ntawm cov tshuaj niaj hnub no hnyav heev leaning rau hluavtaws kev xaiv los xyuas kom meej cov suture ua tau raws nraim li qhov xav tau yam tsis ua rau qhov mob tsis tsim nyog lossis cov ntaub so ntswg o.
Nkag siab Tensile Strength thiab Knot Security
Ob lub cev lub cev txhais cov kev ntseeg ntawm a suture: tensile zog thiab knot kev ruaj ntseg. Tensile zog hais txog qhov hnyav los yog rub lub suture tuaj yeem tiv taus ua ntej nws tawg. Siab tensile zog yog ib qho tseem ceeb heev rau tuav ua ke cov ntaub so ntswg uas nyob rau hauv nro, xws li ib tug plab phab ntsa kaw los yog ib qho chaw sib koom ua ke. Yog tias suture tawg, qhov txhab qhib, ua rau muaj teeb meem. Polypropylene thiab polyester paub txog kev tswj hwm lawv lub zog dhau lub sijhawm.
Txawm li cas los xij, muaj zog suture tsis muaj nuj nqis yog tias cov knot daim tiab. Knot kev ruaj ntseg yog lub peev xwm ntawm cov ntaub ntawv suture los tuav a knot tsis muaj nws unraveling. Braided sutures feem ntau muab zoo heev knot kev ruaj ntseg vim cov braid muab kev sib txhuam. Monofilament sutures, ua du, tuaj yeem ua tau nplua thiab tuaj yeem muaj tsis zoo pob txha ruaj ntseg yog tias tsis khi nrog pov ntxiv (loops). A tus kws phais plab yuav tsum sib npaug cov yam ntxwv no. Piv txwv li, nylon muaj zog tab sis yuav tsum tau ceev faj txheej txheem siv kom ntseeg tau tias knot nyob ruaj ntseg. Yog tias knot poob, cov kaw ua tsis tiav.
Xaiv txoj cai koob thiab xov rau txoj hauj lwm
A suture tsis tshua muaj siv tsis muaj a koob. Qhov tseeb, nyob rau hauv niaj hnub sterile suture nrog rab koob ntim, cov suture yog swaged (txuas) ncaj qha mus rau lub koobCov. Tus koob yuav tsum tau xaiv kom zoo zoo li cov xov. Koob tuaj nyob rau hauv ntau yam duab (kov los yog ncaj) thiab cov ntsiab lus (tapered rau mos nqaij, txiav rau tawv tawv).
Tus txoj kab uas hla ntawm suture kuj tseem ceeb. Suture qhov ntau thiab tsawg yog txhais los ntawm U.S.P. (United States Pharmacopeia) cov qauv, feem ntau txhais los ntawm cov lej xws li 2-0, 3-0, lossis 4-0. Qhov loj dua tus lej ua ntej xoom, qhov thinner lub suture. A 6-0 suture yog zoo heev, siv rau tshuaj pleev ib ce phais ntawm lub ntsej muag los yog kho qhov muag cov txheej txheem los txo cov caws pliav. 1-0 lossis 2-0 suture yog tuab thiab hnyav, siv rau high-tension qhov chaw zoo li lub plab fascia. Siv tuab suture ntawm qhov muag heev laceration yuav ua rau tsis tsim nyog raug mob, thaum siv nyias suture ntawm cov leeg hnyav yuav ua rau tawg. Cov koob thiab suture yuav tsum ua hauj lwm sib haum xeeb nrog cov nqaij.
Daim ntawv thov tshwj xeeb: Los ntawm kev kaw lub plab mus rau kev kho kom zoo nkauj
Txawv kev kho mob scenarios xav tau ntau hom sutures. Hauv mob plawv phais, polypropylene sutures feem ntau yog cov qauv kub vim tias lawv tsis yog thrombogenic (tsis ua rau txhaws) thiab kav mus ib txhis. Rau ib plab phais, qhov twg lub fascia yuav tsum tuav tiv thaiv lub siab ntawm kev ua pa thiab txav, muaj zog, maj mam absorbable lub voj voog lossis ib qho chaw ruaj khov tsis-absorbable suture yog yuav tsum tau.
Hauv tshuaj pleev ib ce phais, lub hom phiaj yog tawm me ntsis kom tsis muaj kab. Ntawm no, zoo monofilament nyiam nylon lossis poliglecaprone yog feem ntau siv vim nws tsim tsawg cov ntaub so ntswg thiab yog li me me caws pliavCov. Rau mucosal cov ntaub so ntswg, zoo li hauv lub qhov ncauj, ceev-absorbing plab lossis Vicryl yog nyiam ces tus neeg mob tsis tas yuav rov qab los tshem tawm suture. Sutures muab tso rau tswv yim raws li lub sijhawm kho ntawm qhov tshwj xeeb nqaijCov. Ib leeg yuav siv sij hawm ntau lub hlis los kho, yog li nws yuav tsum tau siv sijhawm ntev suture. Daim tawv nqaij kho nyob rau hauv hnub, yog li cov suture tuaj yeem raug tshem tawm sai.
Mastering Suture Techniques: Nruam vs. cuam tshuam
Tus cov ntaub ntawv suture tsuas yog ib nrab ntawm qhov sib npaug; tus cov txheej txheem suture ua hauj lwm los ntawm cov tus kws phais plab yog lwm ib nrab. Muaj txawv suture qauv. A nruam suture (khiav plooj) yog qhov ceev rau qhov chaw thiab faib qhov nro sib npaug ntawm tag nrho qhov txhab kaw. Nws siv ib daim ntawm cov ntaub ntawv suture. Txawm li cas los xij, yog tias ib qho strand tawg ntawm ib qho twg, tag nrho kaw tuaj yeem rov los.
Xwb, cuam tshuam sutures muaj ntawm tus kheej stitches, txhua tus khi nrog ib qho sib cais knot. Yog ib xaws so, lwm tus nyob twj ywm, tuav lub kaw. Cov txheej txheem no siv sijhawm ntev dua tab sis muaj kev ruaj ntseg ntau dua. Cov txheej txheem siv nyob ntawm qhov ntev ntawm qhov kev txiav thiab kev pheej hmoo ntawm kev kis kab mob. Piv txwv li, nyob rau hauv lub xub ntiag ntawm ib tug abscess los yog kis kab mob, cuam tshuam sutures muaj kev nyab xeeb dua vim tias lawv tso cai rau cov kua dej yog tias tsim nyog. Cov tus kws phais plab xaiv cov txheej txheem uas zoo tshaj plaws suits cov neeg kho tshuab xav tau ntawm lub nqaij thiab kev nyab xeeb ntawm tus neeg mob.
Cov txheej txheem tseem ceeb ntawm Suture tshem tawm
Rau tsis-absorbable sutures, txheej txheem xaus nrog tshem tawm suture. Paub thaum twg tshem tawm stitches yog art. Yog tias nyob rau hauv ntev heev, lub suture tuaj yeem tawm "kev tsheb ciav hlau khiav" nti los yog ua rau hauv lub cov ntaub so ntswg o. Yog tias tshem tawm ntxov dhau, qhov txhab yuav dehisc (qhib).
Feem ntau, sutures ntawm lub ntsej muag raug tshem tawm hauv 3-5 hnub kom tsis txhob muaj caws pliav. Sutures ntawm tawv taub hau lossis pob tw yuav nyob twj ywm rau 7-10 hnub, thaum cov ceg tawv lossis pob qij txha yuav nyob twj ywm rau 14 hnub. Cov txheej txheem yuav tsum tau huv txiab thiab forceps. Cov knot yog lifted, suture yog txiav nyob ze ntawm daim tawv nqaij, thiab rub los ntawm. Nws yog ib qho tseem ceeb kom tsis txhob rub cov kab mob sab nraud ntawm qhov chaw suture los ntawm qhov huv ntawm qhov txhab. Tsim nyog tshem tawm suture kom huv si, cosmetic tag rau lub phais incisions.
Vim li cas Sourcing Correct Suture Material Matters for Hospitals
Rau cov neeg yuav khoom ntim cov txee, nkag siab Ntau Hom ntawm sutures yog ib qho teeb meem ntawm tus neeg mob kev nyab xeeb thiab kev siv nyiaj txiag. Lub tsev kho mob tsis tuaj yeem ua haujlwm yam tsis muaj cov khoom muag sib txawv. Koj xav tau catgut rau OBGYN pawg ntseeg, hnyav nylon rau ER laceration kho, thiab zoo monofilament rau kev phais yas.
Sutures yog siv yuav luag txhua lub tsev kho mob. Ntau hom sutures daws teeb meem sib txawv. Siv a braided suture ntawm qhov txhab mob tuaj yeem ua rau muaj teeb meem, ib yam li siv lub zog tsis muaj zog suture ntawm lub qhov txhab mob hnyav tuaj yeem ua rau tawg. Txawm nws yog natural thiab hluavtaws, lossis absorbable thiab tsis-absorbable sutures, qhov zoo sib xws yog qhov tseem ceeb. Peb xyuas kom meej tias txhua suture peb manufacture, los ntawm cov koob sharpness rau lub tensile zog ntawm cov xov, ua tau raws li cov qauv nruj. Yog vim li cas a suture muab tso rau, nws muaj ib txoj hauj lwm: tuav txhua yam ua ke kom txog thaum lub cev kho nws tus kheej.
