Zombini i-cone conotoxins kunye ne-neurotoxins yenyoka yolwandle ibangela **inkqubela phambili ye-flaccid yokuphefumla ukukhubazeka ** ngelixa ixhoba lisezingqondweni ngokupheleleyo.
2. UKULUMWA KWECINE OKANYE UKULUMWA KWENYOKA YOLWANDLE: Faka iBandage yokuKhuthaza uShicilelo (PIB) kunye nokuqhina okuqinileyo kwimizuzwana engama-60, kwaye ugcine ixhoba lingashukumi ngokupheleleyo.
3. Ngaba HAYI uhlambe indawo yokulunywa yinyoka yolwandle eOstreliya (iilebhu zasesibhedlele zinokuswabha ulusu lweKit yokuFumana ubuhlungu ukuba kuyimfuneko).
4. Bopha i-10- ukuya kwi-15-centimeter ububanzi be-elastic bandage* ngokuqinileyo phezu kwendawo yokulunywa okanye yokulunywa, uze usongele phantsi uye kwiminwe okanye iinzwane kunye nokunyuka ukuya ekhwapheni okanye kwi-groin ku 40 ukuya ku-70 mmHg (ukuqina okusetyenziselwa iqatha elikrunekileyo). Bopha iqhina eliqinileyo kwilungu kwaye uthwale isigulana esisicaba nge-stretcher.
5. Bukela iinkophe zexhoba, intetho, ukuginya, kunye nokuphefumla rhoqo ngemizuzu emi-2; ukuba ukuphefumla kuba nzulu okanye kuyeka, qalisa ukuphefumla ngokukhawuleza (umlomo-to-emlonyeni, i-pocket mask, okanye i-bag-valve-mask). Ngenxa yokuba akukho **NO-antivenin ye-Cone Snail sting *, umoya wokungenisa umoya owenziweyo (ukuhlangula ukuphefumla elunxwemeni / kwisikhephe, kulandele isibhedlele sokungenisa umoya wesibhedlele kwi-12% ukuya kwiiyure ze-48) ukusindisa ubomi ukuya kwiiyure ze-10) icoca ii-cononotoxins ezibuyiselwa umva.
6. Ungaze ungayihoyi i-pinprick engenabuhlungu emva kokuphatha umnatha wokuloba okanye ukuhamba emanzini ashushu e-Indo-Pacific. Ngaphezulu kweepesenti ezingama-80 zokulunywa kweNyoka yoLwandle (Hydrophiinae) ayibuhlungu kwaphela** kwaye ayibonisi ukudumba kwendawo, ukukhokela abalobi kunye nabahlukahlukeneyo ukungayihoyi into yokuluma de kube yi-1 ukuya kwiiyure ze-4 kamva (i-eyelid i-eyelid) iintlungu zezihlunu, kunye nomchamo omnyama/omnyama (myoglobinuria)** kubonakala.
7. KWENKQATHA YENQATHA YAMEVA (Acanthaster planci) UKWENZAKALA KOMNQO: UNGAZE ufake iBandage yokuKhusela iPressure Immobilization. Endaweni yoko, rhola ngobunono naziphi na izihlunu ezinkulu ezithe tyaba ezithe tyaba ngaphandle kokuwatyumza, kwaye untywilisele isandla okanye unyawo oluhlabayo kumanzi ashushu ku-42 ukuya ku-300 ukuya kutsho kwi-1 ℃ Imizuzu engama-90 ukuvala i-heat-labile i-plastertoxins kunye neesaponins.
8. Esibhedlele: ngenxa yokulunywa kweNyoka yoLwandle, faka i-CSL Sea Snake Antivenom (okanye i-equine Tiger Snake / i-Polyvalent cross-reacting antivenin) kwaye uphathe i-hyperkalemia esongela ubomi (IV calcium gluconate, insulin + dextrose); ukwenzakala kwiCrown-of-Meva, fumana iX-reyi yezicubu ezithambileyo okanye i-ultrasound yokukhupha amacebiso omqolo otyumkileyo.

   • Zinzisa i-myocardium ngokukhawuleza: Nika 10% iCalcium Gluconate (10 ukuya ku-30 mL IV kwimizuzu emi-5) okanye 10% yeCalcium Chloride (5 ukuya kwi-10 mL IV ngomgca osembindini).
   • Shift potassium intracellularly: Infuse Regular Insulin (10 units IV) + 50 mL of 50% Dextrose (25 g glucose), plus high-dose nebulized Albuterol (Salbutamol 10 to 20 mg) kunye **Sodium Bicarbonate (50*EqIV0 acid)
   • ** Susa i-potassium kwaye ukhusele izintso: ** Ukufakela ** i-isotonic crystalloids enobudlova ** ukugcina umchamo ophuma ngaphezu kwe-200 mL / iyure, kwaye uqalise ** i-hemodialysis engxamisekileyo ** ye-refractory hyperkalemia okanye i-oliguric renal failure.

I-Crown-of-Thorns Starfish (Acanthaster planci): I-Plastertoxin Spines, Amanzi ashushu, kunye nokutsalwa¶

1. I-Spine anatomy kwaye kutheni iingcebiso ezigciniweyo zibangela i-synovitis engapheliyo¶

I-Crown-of-Meva-Starfish (Acanthaster planci) yi-asteroid enkulu yasebusuku, i-corallivorous asteroid (ekhula nge-25 ukuya kwi-45 centimeters ngapha nangapha ngeengalo ezi-8 ukuya kwezi-21) egqunywe kumphezulu wayo ngamakhulu enaliti ebukhali, i-4- ukuya kwi-5-centimeter-calcareous spine. - Ihanjiswa Njani Ityhefu: Umnqonqo ngamnye ugutyungelwe kwi-sheath ebhityileyo, ebomvu-ntsundu i-sheath yesikhumba edibeneyo equlethe iiseli zamadlala ezikhupha i-plastertoxins I kunye ne-II (i-enzymes enamandla ye-phospholipase A2 eyi-hemolytic, myotoxic, kunye ne-mouse-lethal), **iseli ye-asterosatealle glycosides (iseli ye-asterosateal-like glycosides) i-membrane kwaye ibangele ukukhululwa kwe-histamine kunye ne-prostaglandin), kunye ne-histamine-like amines. - Kutheni iSpines Siqhawuke: Ngenxa yokuba umqolo womqolo unamarhashalala, i-brittle lattice ye-calcium carbonate crystal (stereom), ukunyathela okanye ukuxukuxa ngokuchasene ne-Acanthaster planci iqhuba imiqolo emininzi ngeebhuthi okanye ulusu olungenanto, apho iingcebiso ezinqabilo zikrazula zigungxulwe phantsi komqwebedu odityanisiweyo wolusu/unyawo oluyityhefu ngaphakathi/unyawo oluyityhefu ii-capsules ezidibeneyo. - I-Clinical Syndrome:** Ngephanyazo, iintlungu ezitshisayo eziqhaqhazelisa amazinyo eziphuma emlzeni, ukopha ngokukhawuleza kwimingxunya emininzi yokugqobhoza, i-edema yendawo ekhawulezayo kunye ne-ecchymosis, kunye nokwenzakala kwe-multi-spine, isicaphucaphu, ukugabha ixesha elide, isiyezi, i-paresthesias, kunye ne-lymphadenitis yengingqi. Ukuba iingcebiso ezingaphantsi kwe-calcareous spine kunye ne-epithelium enetyhefu zishiywe ngaphakathi kwesandla okanye unyawo, isigulane sikhula ** i-granulomas yangaphandle, i-secondary * Vibrio * / * I-Mycobacterium marinum * usulelo, kunye ne-tenosynovitis engapheliyo ye-granulomatous okanye i-arthritis **.

2. Ulawulo lwamanyathelo ngamanyathelo okulimala kwe-Crown-of-Thorns Starfish¶

1. UNGAZE Ufake i-Bandage ye-Pressure Immobilization (PIB): Ukusonga i-bandage eqinile phezu kwe-Acanthaster spines iqhuba i-brittle calcareous shards ibe nzulu kwi-tendon kunye namalungu kwaye igxininise i-saponins ye-cytolytic kunye ne-phospholipase A2 kwindawo.
2. Ukuntywiliselwa kwaManzi ashushu kwangoko (ama-42 ukuya kuma-45 ngokukaCelsius [108 ukuya kwi-113 ngokukaFahrenheit]):
3. Gxininisa isandla esilumayo, unyawo, okanye ilungu ku-amanzi ashushu ngokunyamezelayo (42 ukuya ku-45 C / 108 ukuya ku-113 F, avavanywe kuqala ngesandla esingenzakali) kangangemizuzu engama-30 ukuya kuma-90.
4. Iiprotheyini ze-Plastertoxins kunye nee-pain-mediting proteins zi-**-heat-labile **; Ukucwiliswa kwamanzi ashushu kunciphisa ngokukhawuleza intlungu ukusuka kwi-9/10 ukuya kumanqanaba alawulekayo ngaphakathi kwe-20 ukuya kwi-30 imizuzu.
5. Ibhloko yeNerve yeSibhedlele, iRadiographic/Ultrasound Localization, kunye nokutsalwa koCando:
6. Su***** uzame ukutyumza izingxobo ezizinzisiweyo ngamatye okanye uzibethelele ngaphakathi kwesikhumba (isenzo soluntu sase-Indo-Pacific esiyingozi esiqhekeza i-calcite ye-porous ibe ngamakhulu amaqhekeza e-micro-granuloma angenakushenxiswa), kwaye musa ukucwina kwiviniga ngethemba lokunyibilikisa i-subdermal spines ngobusuku.
7. Kwiklinikhi okanye esibhedlele, lawula i-** yendawo okanye yengingqi ye-nerve block (i-lidocaine okanye i-bupivacaine) , fumana ** i-soft-tissue plain-film X-rays kunye / okanye i-high-frequency ultrasound ** (yonke i-calcium carbonate Acanthaster spines radiopaque kwi-X-ray **), kwaye usebenzise i-surgical, i-micro-extracts ye-loop Incam yomqolo efakwe ngaphakathi kwaye ukhuhle zonke iziunu zesheath ezimnyama.
8. Ukunkcenkceshela kakhulu nge-saline eqhelekileyo eyinyumba, shiya iipunctures ezinzulu zivulekile ukukhupha, ulawule ** i-tetanus booster **, kwaye umisele **doxycycline (100 mg PO kabini ngosuku) okanye i-ciprofloxacin (500 mg PO kabini yonke imihla) kunye ne-amoxicillin-clavulanate ** iintsuku ezi-5 ukuya kwezi-7 zokugubungela i-vuvul Vibrino, iVibrino, iVibrino, iVibrino, iVibrino, iVibrino, iVibrino, IiAeromonas iintlobo.

Imibuzo edla ngokubuzwa¶

Kutheni le nto i-Geography Cone Snail (Conus geographus) ibizwa ngokuba yi "snail yecuba," kwaye usinde njani xa uhlaselwe?¶

Kwi-Indo-Pacific, i-Conus geographus yafumana igama lesiqhulo elithi "inkumba yesigarethi" ekugqithiseni ukuba emva kokuhlaba, unexesha elaneleyo lokutshaya icuba elinye ngaphambi kokuba kubanjwe ukuphefumla. Ngokwenyani yeklinikhi, i-harpoon yayo ye-radular ifaka i-cocktail ye-synchronized ye-alpha-, mu-, kunye ne-omega-conotoxins ethintela ukuhanjiswa kwe-neuromuscular kwiindawo ezintathu ezihlukeneyo, okubangela ukwehla kwe-flaccid ukukhubazeka kunye nokumisa i-diaphragm phakathi kwe-15 ukuya kwi-60 imizuzu. Nangona kungekho antivenin ekhoyo, unokusinda kwipesenti ze-100 zexesha ukuba abahlanguli basebenzise ngokukhawuleza i-Bandage Immobilization Bandage (PIB), yenza umlomo oqhubekayo emlonyeni okanye isikhwama se-valve-mask ukuphefumla ukuphefumla xa ukuphefumla kuyancipha, kwaye ubeke isigulane kwisibhedlele somatshini wokungenisa umoya we-12 kwiiyure ze-48 de umzimba ucoce ngokwemvelo i-conotoxin.

Kwenzeka njani ukuba iNyoka yoLwandle ilunywe ingabi nantlungu kwaphela ekuqaleni?¶

Ngokungafaniyo ne-rattlesnakes okanye i-cobras, iinyoka zaselwandle (i-Hydrophiinae) zavela kwi-venom ngokukodwa ukukhupha iintlanzi kunye ne-eels emanzini kwaye zingabikho i-enzymes yokuchithwa kwezicubu ezibangela intlungu evuthayo kunye nokuvuvukala kwindawo yokuluma. Ukongeza, iifangs zabo zangaphambili ezisisigxina zi-1.5 ukuya kwi-4 yeemilimitha ubude. Ukulunywa yinyoka yolwandle kuvakala ngathi kukudumba okanye ukuba bomvu, ngoko ke abalobi kunye nee-waders bahlala bengayihoyi de kube yimizuzu engama-30 ukuya kwiiyure ezi-4 kamva xa umhlathi wabo utshixa ngokuqinileyo (i-trismus), zonke izihlunu zabo zamathambo ziba buhlungu kakhulu xa zishukuma, kwaye umchamo wabo ujika ujike ukuqhekeka kwemisipha.

Kutheni iNyoka yoLwandle ilunywa ijike umchamo wakho ubemnyama kwaye imise intliziyo yakho?¶

Ityhefu yenyoka yolwandle iqulethe i-systemic phospholipase A2 myotoxins ejikeleza egazini kwaye inyibilikise iinwebu zangaphandle zemicu yemisipha emzimbeni wonke. Njengoko iiseli zezihlunu zigqabhuka zivuleka, zilahla izixa ezikhulu zeprotheyini ye-myoglobin emnyama-emdaka egazini, ethi ihluze ezintso kwaye ijike umchamo ube mnyama bubomvu-mdaka okanye amalahle-mnyama (myoglobinuria). Kwangaxeshanye, iiseli ze-muscle ezigqabhukileyo zilahla inani elikhulu le-potassium ye-intracellular egazini (hyperkalemia), enokubangela ukubanjwa kwentliziyo ebulalayo (i-fibrillation ye-ventricular) ngaphakathi kweeyure ngaphandle kokuba iphathwe nge-CSL Sea Snake Antivenom, i-intravenous calcium gluconate, kunye ne-insulin ene-glucose.

Ngaba kufuneka ndisebenzise i-Bandage ye-Pressure Immobilization okanye amanzi ashushu kwi-Crown-of-Meva Starfish sting?¶

Sebenzisa ukuntywiliselwa emanzini ashushu (ama-42 ukuya kuma-45 ngokukaCelsius [i-108 ukuya kwi-113 ngokukaCelsius] kangangemizuzu engama-30 ukuya kwengama-90), kwaye UNGAZE ufake iBandage lokuKhusela iPressure Immobilization (PIB) kukwenzakala kwiCrown-of-Thorns Starfish (Acanthaster planci). Ukusonga ibhandeji eliqinileyo phezu kwenxeba le-starfish kutyhala i-brittle calcium carbonate spines ingene nzulu kumalungu akho kunye nemisipha kwaye ibambe i-saponins kunye ne-plastertoxins kwindawo enye. Ukucwina unyawo okanye isandla emanzini ashushu kuchaza i-plastertoxins evakalelwa ngubushushu kwaye ithomalalisa iintlungu ezivuthayo de ugqirha angathatha i-X-reyi kwaye asuse ngotyando iingcebiso zomnqonqo.

Kutheni ungenako ukushiya nje i-Crown-of-Meva ye-Starfish esaphukileyo esandleni sakho okanye unyawo lwakho ukuze inyibilike?¶

Nangona imiqolo ye-Crown-of-Meva ye-Starfish yenziwe nge-porous calcium carbonate, umqolo ngamnye uqatywe kwi-sheath yesikhumba esinetyhefu egcwele i-plastertoxins kunye ne-saponins, kunye neebhaktheriya zaselwandle ezifana ne-Vibrio kunye ne-Mycobacterium marinum. Ukuba iingcebiso zomnqonqo ezaphukileyo kunye ne-shreds yesikhumba esinetyhefu zihlala zifakwe phantsi kwedermis okanye ngaphakathi komnwe okanye inzwane edibeneyo, umzimba wenza i-granulomas ebuhlungu yangaphandle kunye ne-granulomatous synovitis engapheliyo enokuthi iqinise idibeneyo. Yonke i-spine shard efakwe ngaphakathi ibonakala kwi-X-reyi yezicubu ezithambileyo okanye kwi-ultrasound kwaye kufuneka isuswe ngotyando phantsi kwe-nerve block.

Ngaba inkumba yekhowuni ingakuhlaba kwiiglavu okanye xa ungaphakathi kwingxowa yokuqokelela umnatha?¶

Ewe. Ungaze uthabathe iqokobhe lekhowuni ephilayo ngezandla ezingenanto okanye iiglavu, kwaye ungaze ubeke iqokobhe lekhowuni ephilayo kwipokotho ye-wetsuit okanye ibhegi yemesh ejinga emlenzeni okanye esinqeni sakho. I-piscivorous cone inkumba efana ne-Conus geographus okanye i-Conus striatus inokwandisa i-proboscis yayo eguquguqukayo ukuya ekupheleni kweqokobhe layo kwaye itshise inaliti yayo ebukhali ebukhali kwingxowa yelaphu, iiglavu zokuntywila, kunye neempahla ezimanzi ezibhityileyo.
