I-Therother hypothermia yindlela yokwelashwa esetshenziswe ngemuva kokuboshwa kwenhliziyo, okuqukethe ukupholisa umzimba ukunciphisa ubungozi bokulimala kwemizwa nokwakheka kwamahlule, okwandisa amathuba okusinda nokuvimbela i-sequelae. Ngaphezu kwalokho, le ndlela ingasetshenziswa ezimeni ezinjengokulimala kwengqondo ebuhlungu kubantu abadala, isifo sokushaywa yischemic kanye ne-hepatic encephalopathy.

Le ndlela kufanele iqalwe ngokushesha okukhulu ngemuva kokuboshwa kwenhliziyo, ngoba igazi liyema ngokushesha ukuhambisa inani elidingekayo lomoya-mpilo ukuze ubuchopho busebenze, kepha lungabambezeleka kuze kufike emahoreni ayisithupha ngemuva kokuba inhliziyo ishaye futhi. Kodwa-ke, kulezi zimo ubungozi bokusungula ama-sequelae bukhulu kakhulu.

Kwenziwa kanjani

Le nqubo iqukethe izigaba ezi-3:

• Isigaba sokungeniswa: izinga lokushisa lomzimba liyancipha lize lifinyelele emazingeni okushisa aphakathi kuka-32 no-36ºC;
• Isigaba sesondlo: kubhekwa izinga lokushisa, umfutho wegazi, ukushaya kwenhliziyo kanye nesilinganiso sokuphefumula;
• Phinda isigaba: izinga lokushisa lomuntu lenyuka kancane futhi ngendlela elawulwayo ukuze kufinyelele amazinga okushisa aphakathi kuka-36 no-37.5º.

Ngokupholisa umzimba, odokotela bangasebenzisa amasu amaningi, kepha, okusetshenziswa kakhulu kufaka ukusetshenziswa kwamaphakethe e-ice, omatilasi abashisayo, isigqoko sokuvikela ice noma u-ayisikhilimu ngqo emthanjeni weziguli, kuze kube yilapho izinga lokushisa lifinyelela amanani aphakathi kuka-32 no 36 ° C. Ngaphezu kwalokho, iqembu lezokwelapha libuye lisebenzise amakhambi okuphumula ukuqinisekisa induduzo yomuntu nokuvikela ukubukeka kokuthuthumela

Ngokuvamile, i-hypothermia igcinwa amahora angama-24 futhi, ngaleso sikhathi, izinga lokushaya kwenhliziyo, umfutho wegazi nezinye izimpawu ezibalulekile zihlale ziqashwe ngumhlengikazi ukuze kugwenywe izinkinga ezinkulu. Ngemuva kwalesi sikhathi, umzimba ufudunyezwa kancane uze ufike ezingeni lokushisa lika-37ºC.

Kungani kusebenza

Indlela yokusebenza yale nqubo ayikaziwa ngokugcwele, kepha, kukholelwa ukuthi ukwehla kwezinga lokushisa komzimba kunciphisa ukusebenza kukagesi ebuchosheni, kunciphise ukusetshenziswa komoya-mpilo. Ngaleyo ndlela, noma ngabe inhliziyo ayimpompi inani legazi elidingekayo, ubuchopho buqhubeka nokuba ne-oxygen eyidingayo ukuze isebenze.

Ngaphezu kwalokho, ukwehlisa ukushisa komzimba kusiza futhi ukuvimbela ukukhula kokuvuvukala kwezicubu zobuchopho, okwandisa ubungozi bokulimala kuma-neurons.

Izinkinga ezingenzeka

Yize kuyindlela ephephe kakhulu, lapho yenziwa esibhedlela, i-hypothermia yokwelapha nayo inezingozi ezithile, njenge:

• Shintsha ekushayeni kwenhliziyo, ngenxa yokwehla okuphawulekayo kokushaya kwenhliziyo;
• Ukwehla kwe-coagulation, okwandisa ingozi yokuphuma kwegazi;
• Ingozi yokwanda kwezifo;
• Inani elinyukile likashukela egazini.

Ngenxa yalezi zinkinga, le nqubo ingenziwa kuphela e-Intensive Care Unit kanye nethimba lezokwelapha eliqeqeshiwe, ngoba kuyadingeka ukwenza ukuhlolwa okuningi emahoreni angama-24, ukunciphisa amathuba okuthuthukisa noma yiluphi uhlobo lwenkinga.
