Nguvu ya sumu

Kuumwa

Sumu hutoka kupitia meno yake ya sumu au meno anapouma.

Sumu yake hufanya nini?

This snake is highly venomous. Its venom causes pain, swelling, bruising and necrosis (death of body tissue), and it can also lead to abscesses. The venom disturbs blood clotting: the venom has thrombin-like proteases, which slow the clotting of fibrinogen, a protein needed to form clots. Bites can also cause high blood pressure and collapse.1

Ana hatari gani kwa watu?

Hatari kwa watu: Hatari sanaAnaweza kumuua mtu asiyepata matibabu.

This species is one of the main causes of snakebite in Argentina. Between 1960 and 1975, about 500 cases were reported there each year, and 80% of them were attributed to one subspecies, B. n. diporus. In a study of 18 bite cases admitted to a hospital in São Paulo from 1975 to 1992, all patients had pain, 83% had swelling, 50% had bruising, 17% had necrosis and 12% developed coagulopathy (a clotting disorder).1

Habari njema: madaktari wana dawa (ya kuzuia sumu) au matibabu ya hili.1

Akiuma

  • Three antivenins made by the Instituto Butantan in Brazil can be used to treat bites from this species. Treatment with heparin might help the clotting problems caused by the venom.1
  • Mweke mtu bila kutikisika na mtulivu, weka kiungo kilichoumwa usawa wa moyo, ondoa pete na vitu vinavyobana, na umpeleke hospitali haraka.

Daima piga namba ya dharura kwanza (112, 000, 911). Huu ni mwongozo wa jumla wa huduma ya kwanza, si ushauri wa kitabibu. Misingi ya huduma ya kwanza

Kaa salama

  • Kamwe usimguse, kumkamata wala kumchokoza mnyama wa porini, hata akiwa mdogo, na hata akionekana amelala au amekufa.
  • Mpe nafasi. Ukikutana naye, tulia, rudi nyuma polepole na umwache aende zake.
  • Akikuuma: tulia, usitikisike, piga namba yako ya dharura (112, 000, 911) au nenda hospitali haraka. Kumbuka alivyoonekana, picha husaidia.

Hakuwindi wewe. Hutumia sumu yake kukamata chakula au kujilinda, na hupendelea zaidi kujificha. Zaidi kuhusu kukaa salama
