- Kufuneka usebenzise i-heparin rhoqo ngaphambi kokuba uxinzelelwe kwimithambo yegazi (ngaphandle kokuba isigulane sinembali ye-heparin induced thrombopenia (HIT))
- Ukuqonda umahluko obalulekileyo phakathi kwezixhobo 'zokubopha' (umz. i-DeBakey vascular clamp vs i-Overholt clamp)
- Ukusebenzisa ii-arteries clamps ngokuchanekileyo (qaphela indlela ezibekwe ngayo ii-calcified plaques)
- Ukwenza i-arteriotomy ngokuchanekileyo (i-scalpel engu-Nr. 11 (phezulu!) kunye nesikere sikaPotts)
- Ukuphatha ii-forceps ngokuchanekileyo ukuze ungonakalisi iindonga zemithambo yegazi (musa ukuzicinezela)
- Ukubeka inaliti ngokuchanekileyo kwindawo yokubamba inaliti (ngesiqhelo i-1/3 ukuya kwi-2/3; i-30° phambili)
- Ukwamkela izixhobo ezisebenza ngendlela echanekileyo kunye nendawo umzimba neengalo ezibekwe kuyo
- Ukuthunga ngokuchanekileyo eludongeni lwemithambo yegazi (icala elithe nkqo)
- Ukuqondisa izithungo ngokuchanekileyo: ukusukangaphandle nangaphakathikwimithambo yegazi nasekuphumeni kwayo (ukuthintela ukuqhekeka);ngaphandle ngaphakathikwiiprostheses (kwaye, ukuba kuyimfuneko, kwimithambo yegazi ekhokelela ekungeneni
- Ukungaze ubambe imithungo ngezixhobo (ingonakala okanye yaphuke)
- Ukusoloko ujikeleze udonga lwemithambo yegazi (ukuthintela ukudibana komjelo wegazi nezicubu ezidityanisiweyo)
- Ukuqonda izinto ezilungileyo nezingalunganga nge-sutures eziphazamisekileyo vs ukusebenzisa i-sutures
- Ukuqonda indawo efanelekileyo yokufakwa kwe-suture kwi-sutures ezibalekayo ukuqinisekisa ukuba i-suture iqinile (ulwalathiso oluya phambili kuyo yonke i-stitch, umgama omfutshane phakathi kokungena nokuphuma kwe-stitch)
- Njengomncedisi: apho ubambe khona umthungo ukuze ubambe umgca womthungo, phepha ukujika umthungo oseleyo kodwa nika ithuba elaneleyo lokuthungwa okulandelayo (umgaqo we-45% ukuya kwi-55%).
- Njengomncedisi: ukutsala umthungo kwicala lomthungo, kungekhona ngasemva (ukuthintela impembelelo ye-pursestring
- Njengomncedisi: ukuvumela ugqirha ukuba alungise izicubu kuqalangaphambiukutsala umthungo (ukuthintela ukopha komngxuma womthungo)
- Ukuhlanjwa rhoqo ngaphambi kokuba kuvalwe, kudityaniswe kwaye kususwe iikliphu
- Ii-arteriotomies ezinqamlezileyo ezi-2x / ezi-2x ezinde. Vala zombini ii-arteriotomies ngeendlela zombini: eziphazamisekileyo nezisebenzisa i-sutures, ngokulandelelana kwazo.
- Ukuphatha udonga lwemithambo yegazi: bamba i-adventitia kuphela nge-forceps yakho
- Ukuqiniswa ngokufanelekileyo kwemithambo yegazi: nikela ingqalelo kwi-plaque, sebenzisa i-vascular clamp, lungisa amandla e-clamp, ungalibali ukunika i-heparin ngaphambi kokuba uyiqiniswe!
- I-Arteriotomy: yisebenzise njenge-scalpel blade Nr 11, i-incision ibambe i-blade iphezulu
- Yandisa i-arteriotomy usebenzisa izikere zePotts
- Ukuphathwa kwemithambo yegazi nge-forceps: musa ukucinezela i-intima, sebenzisa i-forceps njenge-counterforce ngexesha lokuthunga, bamba i-adventitia kuphela
- Bamba isibambi senaliti ngokuchanekileyo
- Indawo yenaliti ngokuchanekileyo
- Thunga zonke iileya zodonga ngestitshi esime nkqo (akukho zistitshi ezithe nkqo)
- Indlela yokuthunga ngaphakathi nangaphandle (kwiindonga zemithambo ukuze kuthintelwe ukuqhekeka)
- Ukusebenzisana phakathi kwenaliti, isibambi senaliti kunye ne-forceps: inaliti yokuthatha, cwangcisa ukuthunga okulandelayo
Ulawulo lweethagethi zokufunda
- Uguquko
- Ukulungelelaniswa kweestiches
- Ukuqina kwe-suture
