Isishwankathelo seNkqubo zokuFudumeza ulwelo
Injongo ephambili yezifudumezi ze-IV fluid kukufudumala ulwelo olufikelela kubushushu bomzimba okanye ngaphezulu kancinci ukuthintela i-hypothermia ngenxa yokufakwa kwezifudumezi ezibandayo. Iingozi ezinxulumene nokusetyenziswa kwezifudumezi ze-fluid ziquka i-air embolism, i-hemolysis ebangelwa bubushushu kunye nokulimala kwemithambo yegazi, ukuvuza kombane kwindlela yolwelo, usulelo, kunye nokungena koxinzelelo.42
Isixhobo sokufudumala esinolwelo sikwasetyenziswa ngokupheleleyo ekufakweni ngokukhawuleza kweemveliso zegazi elibandayo, ngenxa yemingcipheko yokuma kwentliziyo kunye nokuphazamiseka kwentliziyo (ingakumbi xa i-node ye-sinoatrial ipholisiwe ukuya ngaphantsi kwama-30° C). Ukuma kwentliziyo kuye kwabonakala xa abantu abadala befumana igazi okanye i-plasma ngamanani angaphezu kwe-100 mL/min imizuzu engama-30.40 Umlinganiselo wokubangela ukuma kwentliziyo uphantsi kakhulu ukuba utofelo-gazi lunikezelwa phakathi kwabantwana.
Izifudumezi zolwelo zingahlulwahlulwa ngokubanzi zibe zizixhobo ezenzelwe ukufudumeza ulwelo kwiindawo eziqhelekileyo kunye nezixhobo ezintsonkothileyo ezenzelwe ukuvuselela ngomthamo omkhulu. Ngelixa zonke izifudumezi zolwelo ziqulethe isifudumezi, ulawulo lwe-thermostatic, kwaye, kwiimeko ezininzi, ukufunda ubushushu, izifudumezi zolwelo lokuvuselela zilungiselelwe ukuhamba okuphezulu, kwaye ziyeke ukuhamba komguli xa umoya obalulekileyo ufunyenwe kwityhubhu. Izifudumezi zolwelo ezilula zihambisa ulwelo olufudumeleyo ngamanani afikelela kwi-150 mL/min (kwaye ngamanye amaxesha ngamanani aphezulu, ngeeseti ezikhethekileyo ezilahlwayo kunye nokufakwa koxinzelelo), ngokungafaniyo nezifudumezi zolwelo lokuvuselela ezifudumeza ngempumelelo ulwelo ngamanani okuhamba ukuya kuthi ga kwi-750 ukuya kwi-1000 mL/min (isifudumezi esinye sokuvuselela ulwelo sisusa nesidingo soxinzelelo).
Ukufudumeza ulwelo lwe-IV kunokwenziwa ngokutshintshiselana kobushushu okomileyo, izitshintshi zobushushu ezichasene nombane, ukuntywiliselwa kolwelo, okanye (ngokungasebenzi kakuhle) ngokubeka inxalenye yesekethe yolwelo kufutshane neheater eyahlukileyo (njengesixhobo somoya ophoqelelweyo okanye umatrasi wamanzi ashushu).
