Isixazululo saline sokugqwayiza okumisiwe

Noma ubani onemfundo yezinga eliphezulu lekhemistry angakutshela ukuthi uma izinga lokushisa libanda, ukusabela kwenzeka kancane kancane. Umgomo ofanayo uyasebenza ekuphenduleni emizimbeni yethu: ukusabela kumaseli ethu kuhamba kancane uma imizimba yethu ibanda kakhulu. Lokhu kusho ukuthi amangqamuzana ethu adinga umoya-mpilo omncane uma sikwazi ukwehlisa izinga lokushisa lomzimba wethu. Ingachaza futhi ukuthi kungani abantu benza awe emifuleni eneqhwa namachibi anethuba elingcono lokuvuselelwa imizuzu engamashumi amathathu kamuva kunomuntu owela echibini maphakathi nehlobo.

Odokotela bazi kahle nge-kinetics yasesikoleni esiphakeme. Ngezinye izikhathi, ngaphambi kokuhlinzwa isikhathi eside, izinga lokushisa lomzimba liyehliswa kusetshenziswa amaphakethe eqhwa kanye nenqubo yokuzungeza igazi ngesistimu yokupholisa ukuze kuthengwe isikhathi. Nokho, le nqubo ithatha isikhathi esiningi nokuzilungiselela. Futhi uma othile engena ku-ER ngokulimala okudabukisayo futhi elahlekelwa igazi ngokushesha, ukuzipholisa kancane akuyona inketho.

Kodwa-ke, konke lokhu kungaxazululwa esikhathini esizayo esiseduze, ngoba ngoMeyi 2014 odokotela basesibhedlela i-UPMC Presbyterian ePittsburgh baqala ukuhlolwa kwabantu. "ukugqwayiza okumisiwe", kusetshenziswa izisulu zokudutshulwa okungenzeka zilimele kakhulu njengezifundo. Emzamweni wokuthenga isikhathi, odokotela bashintsha igazi leziguli ezilimele bafake ingxube ye-saline, epholisa umzimba futhi icishe imise ukusebenza kwamangqamuzana. 

Ukukhipha usawoti emithanjeni yomuntu othile kusho ukungaphefumuli futhi akukho msebenzi wobuchopho - owaziwa nangokuthi ukufa. Nokho amaseli ahlala ephila: asebenza kancane, kodwa ayasebenza noma kunjalo. Ngemva kwamahora ambalwa okuhlinzwa okusindisa ukuphila, odokotela babuyisela igazi esigulini ukuze sifudumale futhi siphile ngokoqobo. 

UDkt. Hasan Alam we-Massachusetts General Hospital e-Boston wenze le nqubo yopopayi emisiwe ezingulubeni ezine izinga lempumelelo elingamaphesenti angamashumi ayisishiyagalolunye. Unethemba mayelana nezilingo zabantu futhi utshelwe I-Sydney Morning Herald emuva ngo-2006, "Uma inhliziyo iqala ukushaya futhi igazi liqala ukumpompa, voila, unesinye isilwane esibuya ngaphesheya ... Ngobuchwepheshe, ngicabanga ukuthi singakwenza kubantu."
