Ukuphepha kwezilwane ezifuywayo zesimo sezulu esibandayo: i-frostbite triage, i-ice melt toxicology, namazinga okukhosela ebusika¶

Iziphepho zasebusika, amakhaza ashubisa umnkantsha, neziphepho zeqhwa ziletha izingozi ezinkulu, ezisongela ukuphila ezilwaneni ezikanye nazo. Nakuba izinganekwane ezidumile zisikisela ukuthi izilwane zinamajazi oboya futhi ngokwemvelo zingakwazi ukumelana namazinga okushisa aqandayo, iqiniso lebhayoloji lihluke kakhulu. Izinja, amakati, nezilwane ezifuywayo ezincane zisengozini yokuhlaselwa yi-hypothermia, isithwathwa, ubuthi bamakhemikhali ophuma emigwaqweni yasemgwaqweni, kanye nokwehluleka kwezitho eziyingozi ngenxa yokugwinywa kwezimoto ezinqanda ukuqhwa. Njalo ebusika, izinkulungwane zezilwane ezikanye nazo ziba nokulimala okungavinjelwa, izicubu ze-necrosis, nokuchayeka okubulalayo ngenxa yokuthi abanakekeli bayehluleka ukuqaphela imingcele yokuphila kwezilwane ezifuywayo.

Ukunakekelwa kwezilwane ezifuywayo zesimo sezulu esibandayo kudinga ukuqonda ngokuqhathanisa isayensi yemvelo yezilwane ezincelisayo, izindlela ezinobuthi, nobunjiniyela obufanele bezemvelo. Lapho amazinga okushisa asendaweni ehla, imithambo yegazi ezungezile iyacinana ukuze ivikele izitho zangaphakathi, ishiya izindlebe, imisila, nezidladla zisengozini yokuba sengozini yokubanda. Imizila yokuhamba yangaphandle ingcoliswa usawoti wamakhemikhali e-caustic ashisa izidladla futhi abangele ushevu wesistimu lapho akhothwa. Khonamanjalo, amakati omphakathi angaphandle nezinja ezisebenzayo ezishiywe ezindaweni zokukhosela ezingafakwanga zivalwe noma ezingalaliswe ngendlela efanele zibhekana ne-hypothermia esheshayo lapho umswakama uphendula okombhede kube amashidi eqhwa aqinile.

Lo mhlahlandlela uhlinzeka ngezinqubo zobuchwepheshe, eziqondaniswe nodokotela wezilwane zokuphatha izilwane ezihambisana nazo esimweni sezulu esibanda. Inikeza imininingwane nge-physiology ye-canine ne-feline thermoregulation, isiteji somtholampilo kanye nezinqubo zokuvuselela kabusha zesithwathwa, izimiso eziyisisekelo zokuvuselela kabusha ukuvimbela ukushaqeka kwangemuva kwezilwane ezifuywayo ezishisayo, ubuthi obuqhathaniswayo bamakhemikhali ancibilika eqhweni kanye ne-ethylene glycol antifreeze, izindlela zokuvikela izidladla, kanye namazinga wobunjiniyela wendawo yangaphandle yasebusika. Ukuze uthole ukulungiselelwa okubanzi kwekhaya lesiphepho sasebusika, bheka ukulungela isiphepho sasebusika ekhaya futhi izilwane ezifuywayo ezimweni eziphuthumayo. Ngohlelo lokuhlinzekwa kwezokwelapha, thintana ikhithi yosizo lokuqala lwesilwane kanye nokuqeqeshwa kwekhreyithi futhi ubuthi bezilwane ezifuywayo kanye nokudla okunobuthi.

Yenza lokhu manje¶

1. Letha izinja ezifuywayo, amakati, nezilwane ezifuywayo ezincane endlini lapho amazinga okushisa e-ambient ewela ngaphansi kuka-0 °C (32 °F) noma amakhaza ehla ngaphansi -4 °C (25 °F). Khawulela amakhefu okugeza ezilwane ezifuywayo ezisengozini abe yimizuzu emi-5 ukuya kweyi-10.
2. Geza futhi womise izidladla, imilenze, nesisu ngokushesha ngemva kokuhamba ebusika. Sebenzisa amanzi afudumele nethawula ukuze ususe amadeyisi, usawoti, namabhola eqhwa ngaphambi kokuba isilwane sikhothe isikhumba saso.
3. Hlola izindlebe, amathiphu omsila, nezidladla ukuze uthole isithwathwa (umbala ophaphathekile noma oluhlaza okwesibhakabhaka, ukubanda, ukuba ndikindiki). Zifudumeze ngobumnene ngamanzi apholile (38 °C ukuya ku-40 °C / 100 °F kuya ku-104 °F); ungalokothi usebenzise amanzi ashisayo noma ukungqubuzana.
4. Uma i-antifreeze (i-ethylene glycol) noma usawoti wamakhemikhali udliwe, thintana nokulawula ubuthi obuphuthumayo bezilwane ngokushesha. I-antifreeze ibangela i-necrosis ebulalayo yezinso ngaphandle kwama-antidotes asheshayo.
5. Umphakathi wasekhaya noma izilwane ezisebenzayo ezindaweni zokukhosela eziphakeme, ezivalekile ezibekwe ngotshani obuhlanzekile. Ungalokothi usebenzise izingubo zokulala, amathawula, noma i-hay, emunca umswakama futhi ibe yiqhwa eqinile.
6. Nikeza amanzi okuphuza amasha ezitsheni ezishisayo. Izilwane azikwazi ukukhipha amanzi ngokudla iqhwa, elehlisa izinga lokushisa lomzimba.

I-Veterinary physiology kanye nokubekezelelana okubandayo ezilwaneni ezihambisana nazo¶

Izilwane ezingabangane zigcina izinga lokushisa langaphakathi lomzimba ngokuzivumelanisa nezimo eziyinkimbinkimbi ze-metabolic, i-vascular, kanye nokuziphatha. Kodwa-ke, amandla abo okubekezelela amazinga okushisa angaphansi kweqhwa ayahluka kakhulu kuzo zonke izinhlobo zezilwane, izinhlobo, ukuhlangana komzimba, kanye nezimo zezempilo.

Izinga lokushisa lomzimba elijwayelekile kanye ne-thermoregulation¶

Izinga lokushisa elivamile le-canine core lisukela ku-38.3 °C kuya ku-39.2 °C (101.0 °F kuya ku-102.5 °F), kuyilapho i-feline evamile ingu-38.1 °C kuya ku-39.2 °C (100.5 °F kuya ku-102.5 °F). Izilwane ezingabangane zilawula izinga lokushisa ngokusebenzisa: - I-thermogenesis eqhaqhazelayo: Ukundindizela kwemisipha okuzenzekelayo kwandisa ukukhiqizwa kokushisa ngamaphesenti angu-200 kuya kwangu-400, kodwa kuqeda ngokushesha i-glycogen yemisipha yamathambo. - I-peripheral vasoconstriction: I-vasoconstriction enozwela ivimba igazi lisuka ezidladleni, ezindlebeni, nomsila liye enkabeni, ivikela izitho ezibalulekile kuyilapho ishiya amaphethelo esengozini yokugodola. - I-Piloerection: Imisipha ye-Arrector pili iphakamisa uboya ukuze ibambe umoya omile esikhumbeni. - Ukugoqa kokuziphatha: Ukudonsa izidladla nekhala ngaphansi komzimba kunciphisa indawo engaphezulu esobala.

Isilinganiso se-Surface-area-to-volume kanye nokuba sengozini kohlobo¶

Ukulahlekelwa ukushisa kulawulwa isilinganiso sendawo-kuya-kwivolumu. Izinhlobo zamathoyizi namakati anezilinganiso eziphezulu zendawo-to-volume, alahlekelwa ukushisa ngokushesha kakhulu kunezinhlobo ezinkulu. Ukwakheka kwejazi kuphinde kunqume ukuzivikela okushisayo: Izinhlobo zasenyakatho ezinamekwe kabili (Huskies, Malamutes) zinamajazi angaphansi aminyene ngaphansi kwezinwele ezivikela amanzi, kanti izinhlobo ezimbozwe ngombala owodwa (amaGreyhound, ama-Boxers) azinawo amajazi angaphansi futhi alahlekelwa ukushisa ngokushesha. Ngaphezu kwalokho, ngenxa yokuthi ukuguquguquka kwe-thermal yamanzi kuphindwe izikhathi ezingu-24 kunomoya, uboya obumanzi bubhidliza ukwahlukanisa, kusheshisa i-hypothermia ngokuphindwe kamashumi amabili.

Umthelela wokuphila weminyaka yobudala, isimo somzimba, nesifo esingamahlalakhona¶

Izimo zezempilo ezingaphansi zilimaza kakhulu ukuzivikela komzimba kwesilwane emakhazeni: - Imidlwane namakati: Izilwane ezisencane zinezikhungo ezingavuthiwe zokulawula ukushisa ku-hypothalamus, amafutha omzimba amancane angaphansi kwesikhumba, kanye nemithombo ye-glycogen entekenteke, ezenza zingakwazi ukugcina ukushisa komzimba okungaphakathi emoyeni obandayo. - Izilwane ezifuywayo ezindala: Izilwane ezindala zibonisa amazinga ancishisiwe we-metabolic, isinxephezelo esikhubazekile senhliziyo nemithambo yegazi, nokulahlekelwa kwemisipha ethambile. Isimo sezulu esibandayo sidala ukuqina okukhulu kanye nokuqubuka kobuhlungu ezilwaneni ezine-osteoarthritis, zizenze zingathandi ukuhamba noma ukuqeda ngaphandle. - I-Hypothyroidism kanye nokuphazamiseka kwe-endocrine: Izinja ezine-hypothyroidism zihlushwa ukuncipha kwamazinga e-basal metabolic kanye nokukhiqizwa okungekuhle kokushisa. Izilwane ezinesifo sikashukela i-mellitus, i-Cushing's disease, noma isifo sezinso esingamahlalakhona zinenkinga yokuphazamiseka kokujikeleza kwegazi emithanjeni yegazi, okwandisa kakhulu ingozi yokushaywa yiqhwa. - Isifo senhliziyo nemithambo yegazi: Ukuphefumula komoya ongaphansi kweqanda kubangela i-bronchoconstriction futhi kukhulisa ukumelana nemithambo yamaphaphu, izimpawu eziba zimbi kakhulu ezifuyweni ezifuywayo ezinokwehluleka kwenhliziyo, ukugoqeka koqhoqhoqho, noma isifuba somoya.

I-Frostbite ezifuyweni ezifuywayo: i-pathophysiology, isiteji somtholampilo, kanye nezinqubo zokuvuselela kabusha¶

I-Frostbite i-thermal tissue necrosis ebangelwa ukuchayeka isikhathi eside emazingeni okushisa aqandayo. Ngenkathi i-hypothermia ithinta wonke umzimba, i-frostbite ihlose izicubu ezizungezile ezihlushwa i-vasoconstriction eyedlulele.

I-Pathobiology yokulimala kwezicubu ezibandayo¶

Ukuqhubekela phambili kwe-frostbite kwenzeka ezigabeni ezimbili: ukuqanda okuqondile kwamaselula kanye ne-ischemia yesibili ye-vascular: 1. Ukwakheka kwekristalu yeqhwa: Uma amazinga okushisa ezicubu ewela ngaphansi kuka-0 °C (32 °F), amanzi asendaweni engaphandle kwamangqamuzana aba yiqhwa abe amakristalu eqhwa abukhali. Lokhu kwakheka kweqhwa kudonsa amanzi awuketshezi kumaseli nge-osmosis, okubangela ukuphelelwa amanzi emzimbeni okujulile kwe-intracellular kanye nokungalingani kwe-electrolyte. Uma ukuchayeka kuqhubeka, kwakheka amakristalu eqhwa angaphakathi kweseli, abhoboze ulwelwesi lwamaseli futhi abangele i-lysis yeselula. 2. I-Microvascular thrombosis: Njengoba izicubu eziqandisiwe zincibilika, amangqamuzana e-capillary endothelial awonakele akhulula abalamuli abavuvukalayo, i-prostaglandin, ne-thromboxane. Ama-platelet ahlangana ezindongeni zomkhumbi ezilimele, akhe i-microvascular thrombi evimba ukugeleza kwegazi. Ukuvaleka okuphelele kwemithambo kuholela ku-tissue hypoxia, infarction, kanye ne-gangrene eyomile.

Izindawo ze-anatomical ezinobungozi obukhulu ezilwaneni ezihambisanayo¶

I-Frostbite ezinjeni nasemakati yenzeka ngokukhethekile ezindaweni ezisezindaweni eziseduze nemithambo yegazi ezinoboya obuncane: - Amathiphu ezindlebe (pinnae): Isengozini ikakhulukazi ezihlotsheni ezinamadlebe amancane, aqondile, noma ama-penduloous (njengama-Dobermans, ama-Great Danes, ama-Whippets, namakati afuywayo anezinwele ezimfishane). - Ithiphu yomsila: Okuvame ukuthinteka ezinjeni ezinemisila emide, efana nesiswebhu (Ama-Greyhound, Izikhombi) noma amakati achayeke emoyeni oneqhwa. - Amaphedi ezinyawo kanye ne-digital webbing: Ukuthintana nomhlabathi oqandisiwe, amabhola eqhwa apakishwe phakathi kwezinzwane, nosawoti wamakhemikhali kuhluba amafutha emvelo futhi kumise isikhumba sezidladla. - I-Prepuce ne-scrotum: Ezinjeni zesilisa, ukukhululeka okuphansi phezu kweziqweqwe zeqhwa ezijulile kuveza isikhumba esithambile sangasese ukuze sithintane neqhwa neqhwa, okubangela izilonda ezinzima zesithwathwa.

Isiteji somtholampilo se-frostbite ezifuyweni¶

Ukulimala kwe-Frostbite kuvela ezinsukwini ezimbalwa; Ukuvela kokuqala kuvame ukufihla ubukhulu obugcwele be-necrosis yezicubu ezijulile: - Isigaba 1 (I-Frostnip): Isikhumba sibonakala siphaphathekile, simpunga, noma simhlophe qhwa, futhi sizizwa sibanda futhi siqinile. Isilwane singase sibonise izimpawu zobuhlungu lapho sithintwa noma sikhotha ngokweqile ezidladleni. Lapho ukufudumala, isikhumba siphenduka sibebomvu ngokugqamile futhi sivuvuke (i-erythema ne-edema), sihambisana nokulunywa okukhulu nokungakhululeki. Izicubu zihlala zisebenza ngaphandle kokulahlekelwa unomphela. - Isigaba 2 (I-Superficial Frostbite): Ukushuba okugcwele kwesikhumba kubangela ukwakheka kwamabhamuza kanye ne-exudate ecacile noma e-serous phakathi kwamahora angu-24 kuya kwangu-48. Isikhumba siphenduka purplish-blue futhi sizwakala siqinile. Njengoba amabhamuza eqhuma, kuvela izilonda zesikhumba eziluhlaza, ezikhalayo ezisengozini enkulu yokutheleleka ngegciwane lesibili. - Isigaba 3 (I-Deep Frostbite): Ukubanda kungena esikhunjeni nasemafutheni angaphansi kwesikhumba kumsipha, imisipha, noqwanga. Ithishu ethintekile iba nsomi ngokumnyama, bese iqinile, ibanda, ibe mnyama, futhi ingezwa nhlobo ukuthintwa. Emavikini amabili kuya kwamathathu, umugqa ocacile wokuhlukanisa ukwakheka phakathi kwezicubu ezipinki eziphilayo kanye nezicubu ezimnyama ezifayo (i-gangrene eyomile). Izicubu ezifile zigcina ngokuhlehla, ngokuvamile okuholela ekunqanyulweni okungokwemvelo kwamathiphu endlebe noma amasegimenti omsila.

Amaphrothokholi aphephile okufudumala nokuqiniswa kwenkundla¶

Uma kusolwa i-frostbite: 1. Hambisa isilwane endaweni efudumele neyomile ngokushesha. 2. Gxilisa izidladla ezithintekile, izindlebe, noma umsila emanzini apholile aphakathi kuka-38 °C no-40 °C (100 °F kuya ku-104 °F) imizuzu engu-15 ukuya kwangu-20 kuze kube yilapho isikhumba sithambisa futhi siphenduka pink. Ezindlebeni noma umsila, sebenzisa ukucindezela okumanzi okufudumele okuvuselelwe ngokuqhubekayo. 3. Ome kancane ngamathawula ahlanzekile. Ungalokothi uhlikihle, usihlikihle, noma ubhuqe izicubu eziqandisiwe, ezishayela amakristalu eqhwa abukhali ezindongeni zamaseli. 4. Goqa ngokukhululekile nge-gauze oyinyumba engabambeleli bese ufaka ikhola ye-e ukuze uvimbele ukuzilimaza. 5. Ukuthutha kudokotela wezilwane ukuze uthole i-multimodal pain pain kanye nokwelashwa ngama-antibiotic.

Ungalokothi usebenzise amanzi ashisayo (ngaphezu kuka-42 °C / 108 °F), okomisa izinwele, noma amaphedi okushisisa, abangela ukushisa okukhulu. Ungalokothi ufudumale isicubu uma singase siphinde sibe yiqhwa ngesikhathi sokuthutha.

I-Hypothermia ezifuyweni ezifuywayo: ukuhlukaniswa kwemitholampilo kanye nemigomo eyisisekelo yokuvuselela kabusha¶

I-Hypothermia yenzeka lapho ukwehla kokushisa okuhleliwe kudlula umthamo wokukhiqiza ukushisa kwesilwane, kuqhuba izinga lokushisa elingumgogodla we-rectal libe ngaphansi komkhawulo ovamile ongu-38.0 °C (100.4 °F).

Ukuhlukaniswa komtholampilo kwe-hypothermia¶

Umuthi ophuthumayo wezilwane uhlukanisa i-hypothermia ibe izigaba ezintathu ezihlukene zomtholampilo ngokusekelwe ekushiseni kwe-rectal:

I-afterdrop phenomenon kanye nokushaqeka kokuvuselela kabusha okuyisisekelo¶

Umgodi oyingozi kakhulu ekufudumaliseni kabusha isilwane esishisa kakhulu ukushisa izinga lokushisa eliphakathi nendawo.

Ku-hypothermia, amachibi egazi abandayo, ane-acidic emilenzeni ene-vasoconstricted. Ukufaka ukushisa ngqo ezidladleni noma emilenzeni kubangela ukuvaleka kwemithambo kungazelelwe, kubangele ukushaqeka okuvuselelayo (i-systemic hypotension enzima) kanye ne-core afterdrop (igazi elibandayo eline-acidotic eligeleza libuyela enhliziyweni, elidala ukufa kwe-ventricular arrhythmias).

Iphrothokholi ephephile esebenzayo yokuvuselela kabusha¶

Ukuze ugweme ukushaqeka okuvuselelayo, ukushisa kufanele kusetshenziswe kuphela emzimbeni ophakathi (isifuba nesisu) kuyilapho ushiya amaphethelo wodwa: 1. Hlola izinga lokushisa elingunxande usebenzisa ithemometha yezilwane yedijithali enejeli yokugcoba. 2. Susa lonke iqhwa elimanzi, iqhwa, nomswakama ejazini usebenzisa amathawula omile, noma ushaye umoya ofudumele (hhayi oshisayo) kuwo wonke umzimba. 3. Goqa amabhodlela amanzi afudumele (agcwele amanzi cishe ku-39 °C kuya ku-40 °C / 102 °F kuya ku-104 °F) ngamathawula endwangu aminyene. Beka lezi zingubo ezifudumele ngokumelene ne-groin yesilwane, emakhwapheni (i-axillae), nesifuba. Ungalokothi ubeke amabhodlela amanzi ashisayo angenalutho noma izinto zokushisisa zikagesi esikhumbeni sesilwane, okubangela ukusha okubi kakhulu. 4. Goqa sonke isilwane, okuhlanganisa namabhodlela amanzi asongwe, ngezingqimba eziningi zezingubo zoboya ezomile noma ingubo yokulala ekhanyayo ye-mylar ukuze ubambe ukushisa okubambayo. 5. Uma isilwane esifuywayo siqaphela, siqaphile, futhi sikwazi ukugwinya ngokuvamile, nikeza amanani amancane omhluzi wenkukhu efudumele ene-sodium ephansi noma unamathisele wezakhi ezinekhalori ephezulu ukuze unikeze i-glucose ekukhiqizeni ukushisa kwe-metabolic. Ungalokothi uphoqe uketshezi noma ukudla kusilwane esifuywayo esiqulekile noma esiqulekile. 6. Hambisa isilwane ngokushesha esibhedlela esiphuthumayo samahora angama-24 ukuze sihlolwe njalo nge-electrocardiogram, ukwelapha ngoketshezi olufudumalayo olufakwa emthanjeni, kanye nokusekelwa komoyampilo oswakeme.

Chemical ice liyancibilika kanye nobuthi ebusika¶

Ama-deicers amakhemikhali asetshenziswa emigwaqweni, emigwaqweni, nasezindleleni zokushayela aletha izingozi ezimbi kakhulu zokushiswa kwamakhemikhali ezidladleni kanye nobuthi besistimu obusongela ukuphila lapho budliwe.

Ukuqhathanisa kwamakhemikhali amakhemikhali kanye ne-toxicology¶

Ithebula elingezansi liqhathanisa ama-ejenti avamile wokuhuqa ebusika, izindlela zawo zemvelo zobuthi, kanye namaphrofayili azo ezingozi zomtholampilo ezilwaneni ezihambisana nazo:

Ubuthi be-Ethylene glycol (antifreeze): isimo esiphuthumayo sezilwane¶

I-antifreeze yezimoto (i-ethylene glycol) iphakathi kobuthi bezilwane obuyingozi kakhulu. Ukunambitheka kwayo okumnandi kuheha izilwane ezifuywayo, nokho isilinganiso esincane esibulalayo singaphansi kwethisipuni (1.4 mL/kg) kumakati kanye nezipuni ezi-3 (4.4 mL/kg) ezinjeni eziphakathi nendawo.

Ubuthi buqhubeka ngezigaba ezintathu: - Isigaba 1 (amahora angu-0.5 kuye kwayi-12): I-inebriation, i-ataxia, i-drooling, ukuhlanza, i-polyuria, i-polydipsia. - Isigaba sesi-2 (amahora ayi-12 kuye kwangama-24): Ukululama okungamanga ngenkathi i-acidosis enamandla ye-metabolic, i-tachycardia, kanye ne-pulmonary edema ikhula. - Isiteji sesi-3 (amahora angu-12 kuya kwangu-24 emakatini; amahora angu-36 kuya kwangu-72 ezinjeni): Ukuhluleka okukhulu kwezinso. I-glycolic enobuthi ne-oxalic acid akha amakristalu e-calcium oxalate avimbela futhi acekele phansi amashubhu ezinso, abangele i-anuria, uremia, ukuquleka, nokufa.

Ukwelashwa kufanele kuqale phakathi nehora elingu-1 kuye kwayi-3 emakatini namahora ama-4 kuye kwayi-8 ezinjeni. I-Fomepizole (4-MP) noma infusions ye-ethanol yezemithi ivimbela i-alcohol dehydrogenase, ivimbele ukwakheka kwe-metabolite enobuthi.

Amaphrothokholi okuvikela iphedi¶

Ama-Chemical Deicers nosawoti we-crystalline rock abangela ukusha kwamakhemikhali e-caustic, i-dermatitis, nokuqhekeka okubuhlungu phakathi kwezinzwane: 1. Faka izithiyo ze-wax ezivikelayo: Ngaphambi kokuhamba ngezinyawo ngaphandle, sebenzisa i-wax eminyene ye-paw wax (njenge-Musher's Secret noma i-petroleum jelly emhlophe yezinga lokudla) kuwo wonke ama-paw pads naphakathi kwewebhu yedijithali. I-wax idala isihlangu somzimba se-hydrophobic esivimbela amakristalu kasawoti namabhola eqhwa ukuthi anganamatheli esikhumbeni. 2. Zijwayeze izilwane ezifuywayo kumabhuzu okuzivikela: Amabhuzu ezinja ekhwalithi ephezulu afaka amasoli erabha amagebhugebhu, angasheleli kanye namabhande e-hook-and-loop avikelekile ahlinzeka ngokuvikeleka okuphelele ku-ice crusts, usawoti we-rock, nokubanda okukhulu. Faka izinja ezindlini kancane kancane usebenzisa ukuqeqeshwa kokuqinisa ngaphambi kokuba kufike iziphepho zasebusika. 3. Impoqo yokususwa kwezidladla zangemva kokuhamba: Gcina indishi engashoni yamanzi afudumele namathawula e-microfiber ahlanzekile endleleni yakho yokungena. Ngokushesha lapho ubuya kuzo zonke izindawo zokuhamba zangaphandle, cwilisa udladla ngalunye ukuze uncibilikise izinsalela zamakhemikhali, geza kahle phakathi kwawo wonke amawebhu edijithali, futhi wome kancane. Ungalokothi uvumele isilwane sakho esifuywayo sikhothe izidladla zaso kuze kuqedwe lolu chungechunge lokuwasha.

Ubunjiniyela bezindawo zokukhosela zasebusika zangaphandle namazinga omthetho¶

Nakuba izilwane ezihambisana nazo zingaphakathi endlini ngesikhathi sezulu esibandayo, amakati omphakathi azulazulayo, abagadi bemfuyo abasebenzayo, nezinja eziyisihlibhi ngokuvamile zithembele ezakhiweni zangaphandle. Ukwakha indawo yokuhlala yangaphandle yasebusika kudinga ukubambelela ngokuqinile ku-thermal physics kanye nokuphathwa kwe-microclimate.

I-physics ye-outdoor microclimate engineering¶

Indawo yokukhosela yezilwane yangaphandle kufanele isebenze njenge-microclimate eshisayo efudunyezwa kuphela ukushisa komzimba wesilwane: - Usayizi: Ingaphakathi kufanele liminyene ukuze ukushisa komzimba kungalahleki emoyeni ongenalutho. Isilwane kufanele sibe nendawo eyanele nje yokungena, ukuphenduka, nokugoqa (45 by 60 cm / 18 by 24 amayintshi indawo yonyawo lwamakati noma izinja ezincane). - Ukuphakama: Phakamisa iphansi ngo-10 kuya ku-15 cm (ama-intshi angu-4 kuya kwangu-6) kumapulangwe okhuni noma ama-pavers ukuvimbela ukushisa komhlabathi. - I-insulation: Layisha zonke izindawo eziyisithupha ngamabhodi egwebu enziwe nge-polystyrene (XPS) angu-2.5 ukuya ku-5 cm (1 kuya ku-2 amayintshi) awugqinsi. Ungalokothi usebenzise i-fiberglass batt insulation, iziphi izilwane ezihlafunwayo futhi ehlulekayo uma imanzi. - Indlela yokungena: Sika umnyango ophakathi nendawo (15 x 15 cm / 6 x 6 amayintshi wamakati) nge-vinyl flap, udale iphakethe elingaphakathi elingenasici elibheke eningizimu noma empumalanga kude nomoya okhona.

Izinto zokulala: umehluko wempilo noma wokufa phakathi kotshani notshani¶

Ukusebenzisa impahla yokulala engalungile kuyimbangela eyinhloko yokufa kwe-hypothermia ezindaweni zokukhosela zezilwane zangaphandle:

Iziqu zotshani zingamashubhu angenalutho abamba umoya ngaphakathi, asebenza njengamabhodlela e-thermos amancane. Izilwane zimba otshanini obuxegayo, zenza iphakethe elifudumele, elomile lokuzalela elibonisa ukushisa kwemizimba yazo. Ngokuphambene, izingubo zokulala zendwangu notshani kudonsa umswakama wokuphefumula kwezilwane, ukujiya nokuncibilika kweqhwa ezidladleni. Ngemva kwamahora ambalwa, izingubo zokulala ziba yiqhwa zibe yiqhwa eliqinile elidonsa ukushisa emzimbeni wesilwane ngokushesha okuphindwe izikhathi ezingamashumi amabili kunomoya, okubangela i-hypothermia ebulalayo. Pakisha izindawo zokukhosela ezingaphandle zibe maphakathi nophahla ngotshani obusha, bese ubuyisela utshani obungcolile noma obumanzi nyanga zonke.

Amasistimu wamanzi kanye namanzi ashisayo¶

I-hydration ibalulekile ekusindeni kwasebusika. Ukuphelelwa amanzi emzimbeni kuphazamisa ukujikeleza kwegazi, ukusheshisa i-hypothermia kanye ne-frostbite. Izilwane azikwazi ukuhlangabezana nezidingo ze-hydration ngokudla iqhwa: ukudla iqhwa elingaphansi kweqhwa kudinga amandla amakhulu okuncibilika nokufudumala, kuphonsa kakhulu izinga lokushisa lomzimba futhi kubangele i-hypothermia esheshayo.

Faka isitsha samanzi ashisisayo esiqinisekisiwe, esindayo, esilawulwa nge-thermostatically. Bheka izitsha ezifaka insimbi engagqwali nezintambo zikagesi ezigoqwe ngensimbi ezinzima, ezingahlafuni. Uma amandla kagesi engatholakali, sebenzisa izitsha zemfuyo zenjoloba eziwugqinsi, eziguquguqukayo; Irabha eguquguqukayo ivumela abanakekeli ukuthi bakhiphe kalula amabhlogo eqhwa futhi baphinde bagcwalise ngamanzi afudumele izikhathi eziningi nsuku zonke ngaphandle kokuhlehla isiqukathi.

Imithetho yesifunda yokuvikela izilwane ezifuywayo kanye neziyalezo zendawo yokukhosela¶

Ukwehluleka ukuhlinzeka ngokuvikeleka okwanele kwezilwane ezingabangane ngesikhathi sezulu esibi sasebusika kuyicala elishushiswayo ngaphansi kwezimiso zonya lwezilwane kanye nenhlalakahle ezindaweni eziningi:

• I-United States: Ibuswa imithetho yezwe neyendawo. Izifundazwe ezisenyakatho (ePennsylvania ngaphansi kwe-Libre's Law, New York, Illinois) ziphoqelela imithetho eqinile yokusebenzisa ifoni njengemodemu yesimo sezulu esibandayo, okwenza ukusebenzisa ifoni njengemodemu ngaphandle kwemizuzu engama-30 ngaphansi kuka-0 °C (32 °F) kube icala elinonya. Izindawo zokukhosela zangaphandle ezigunyaziwe kufanele ziphakanyiswe, zifakwe i-insulation, futhi zibekwe ngotshani.
• I-Canada: Ilawulwa ngaphansi kwemithetho yesifundazwe (Umthetho we-Ontario PAWS, BC SPCA). Amakhodi alandela izindinganiso ze-Canadian Veterinary Medical Association ezidinga indawo yokukhosela evalekile, enemibhede eyomile egcina ukufudumala okwamukelekayo kanye nokufinyelela kwamanzi angafriziwe.
• E-United Kingdom: Ngaphansi koMthetho Wezenhlalakahle Yezilwane 2006, abanikazi banomsebenzi osemthethweni wokunakekela ukuze bavikele izilwane ezifuywayo ekuhluphekeni. Ukushiya izilwane ezifuywayo emvuleni eqandayo noma emakhazeni ngaphandle kwendawo yokukhosela eshisayo kwephula Isigaba 9, okuholela ekushushisweni nezinhlawulo ze-RSPCA.
• I-European Union: Isekelwe kuNgqungquthela YaseYurophu Yokuvikelwa Kwezilwane Ezifuywayo kanye nemithetho kazwelonke (TierSchG eJalimane, I-Code Rural e-France). Imithetho yase-Germany igunyaza ukuthi kufakwe izindlu zangaphandle ezinotshani futhi ivimbele ukusebenzisa ifoni njengemodemu ngesikhathi esibandayo.
• I-Australia: Ezifundeni ezisezintabeni zaseNew South Wales, e-Victoria, nase-Tasmania, isifunda Sokuvinjelwa Kokuhlukunyezwa Kwezilwane (i-POCTA) sigunyaza indawo yokukhosela eshisayo kanye nokuhlolwa kwezenhlalakahle kwansuku zonke kwezilwane ezisebenzayo nezihambisanayo.

Imibuzo evame ukubuzwa¶

Ingabe izinja zingathola isithwathwa ngokusebenzisa izidladla zazo?¶

Yebo. Nakuba izidladla ze-canine ziqukethe i-epithelium ewugqinsi, ene-keratinized kanye nesistimu yemithambo yegazi ekhethekile ephikisana nokushisa yamanje lapho igazi elifudumele le-arterial lifudumeza igazi elibandayo elibuyayo le-venous, izidladla zihlala zisengozini yokuqandisa indawo. Ukuthintana isikhathi eside nezingqimba zeqhwa ezingaphansi kwezinga-ziro, ukhonkolo oqandisiwe, nosawoti wamakhemikhali we-deicing kususa amafutha emvelo avikelayo, okuholela ekubeni nesithwathwa esinamandla, imifantu ebuhlungu yamaphedi, kanye nezilonda zezicubu. Izidladla kufanele zihlale zivikelekile ngezithiyo ze-wax noma amabhuzu afakiwe ngesikhathi sezulu esibanda.

Iyiphi impahla yokulala ephephe kunazo zonke ongayisebenzisa ngaphakathi kwendawo yokukhosela yamakati ebusika yangaphandle?¶

Utshani obuhlanzekile, obomile bezolimo (i-oat, ibhali, noma utshani lukakolweni) ukuphela kwempahla yokulala ephephile yezindawo zokukhosela izilwane zasebusika zangaphandle. Iziqu zotshani zingamashubhu angenalutho abamba amaphakethe omoya, ahlinzeke ngokufakwa okushisayo okukhethekile kuyilapho exosha umswakama. Akumelwe neze usebenzise izingubo zokulala, amathawula, noma utshani; izindwangu ezilukiwe notshani bumunca umswakama nomswakama ophuma emlonyeni wesilwane, bubanda ngokushesha bube yiqhwa eliqinile, eliqinile elidonsa ukushisa emzimbeni wesilwane futhi libangele i-hypothermia ebulalayo.

Ngingabona kanjani uma inja yami ibanda kakhulu phakathi nohambo lwasebusika?¶

Bheka izinkomba zokuziphatha nezokuma kwendawo: ukuqhaqhazela njalo, ukwehla ijubane, ukukhala, ukungabaza ukuhamba, ukuphakamisa umlenze owodwa noma ngaphezulu endaweni eqandisiwe, ukugoqa uqine ube yibhola lapho umisiwe, kanye nokufuna indawo yokukhosela ngaphansi kwezihlahla noma izimoto ezimile. Uma inja yakho iphakamisa izidladla zayo noma iqhaqhazela ngokuqhubekayo, izinga lokushisa eliyisisekelo liyehla; thatha isilwane esifuywayo noma uhambe uye ngqo ekhaya, ugeze izidladla zaso emanzini afudumele, bese ugoqa inja ngezingubo zokulala ezomile.

Ingabe usawoti we-rock unobuthi uma inja yami noma ikati liwukhotha ezidladleni?¶

Yebo. Usawoti we-Rock uqukethe ngokuyinhloko i-sodium chloride egxilile. Lapho izilwane ezifuywayo zihamba emigwaqweni ephathwayo, amakristalu kasawoti ahlala phakathi kwezinzwane futhi acasule isikhumba. Lapho isilwane sikhotha izidladla zaso endlini ukuze sizihlanze, sidla usawoti ogxilile. Lokhu kubangela ukucasuka okukhulu ngomlomo, ukuvuvukala kwesisu, ukuhlanza, nesifo sohudo. Ngemithamo ephezulu, i-sodium imuncwa ngokushesha egazini, ibangele i-hypernatremia esongela ukuphila, i-cerebral edema, isithuthwane, nokwehluleka kwezinso. Njalo geza izidladla zakho ezifuywayo kahle emanzini afudumele ngokushesha lapho ubuya ohambweni.

Kuthatha isikhathi esingakanani ukuthi isilwane esifuywayo sibe ne-hypothermia esimweni sezulu esibanda kakhulu?¶

Ezifuyweni ezincane, ezimboze kafushane, ezincane, noma ezindala, i-hypothermia ethambile ingakhula emizuzwini eyi-10 kuye kweyi-15 emazingeni okushisa angaphansi kuka -6 °C (20 °F), ikakhulukazi uma izimo zinomoya noma zimanzi. Izinhlobo ezinkulu zasenyakatho ezimbozwe kabili zibekezelela amazinga okushisa angaphansi kukaziro isikhathi eside, kodwa noma isiphi isilwane esinoboya obugcwele udaka oluncibilikayo noma imvula eqandayo singangenwa yi-hypothermia enzima ngaphansi kwemizuzu engama-30. Amakhefu okukhipha ngaphandle kufanele ngaso sonke isikhathi abe mafushane futhi agadwe esimweni sezulu esibi kakhulu sasebusika.

Isitifiketi sosizo lokuqala¶

Ukusabela ngokuphumelelayo ezimweni eziphuthumayo zezilwane ezifuywayo zasebusika, i-toxicosis yamakhemikhali ngengozi, kanye nokulimala okubandayo kwemvelo kudinga amakhono asebenzayo okusebenza. Ukubhalisa kusizo lokuqala lwesilwane esifuywayo esigunyaziwe kanye nesifundo se-CPR nge-American Red Cross, i-St. John Ambulance, i-British Red Cross, noma izinhlangano zokuqeqesha eziphuthumayo zezilwane eziqinisekisiwe kunikeza ukuqeqeshwa okubalulekile. Uzofunda ukukala izimpawu ezibalulekile zesilwane esifuywayo ngokunembile, ukwenza i-canine kanye ne-feline cardiopulmonary resuscitation ngempumelelo, ukufudumala ngokuphepha izilwane ezishisayo ngaphandle kokubangela ukushaqeka okubulalayo kwangemuva kwe-afterdrop, futhi uqondise ukugqokiswa kwenxeba eliphuthumayo elifanele emaphethelweni ayisithwathwa. Isitifiketi esisebenzayo siqinisekisa ukuthi ungathatha isinyathelo esiwujuqu futhi uvikele izilwane zakho lapho iziphepho ezinamandla zasebusika zibambezela usizo lukadokotela wezilwane.

Imithombo ihloliwe¶

Lo mhlahlandlela uhlolwe ngokumelene nezincwadi zomtholampilo wezilwane kanye nezinhlangano ezisemthethweni zenhlalakahle yezilwane: - I-American Veterinary Medical Association (AVMA) imihlahlandlela yezilwane ezifuywayo zesimo sezulu esibandayo - I-ASPCA Animal Poison Control Center (APCC) i-chemical deicer nedatha ye-antifreeze toxicology - I-Pet Poison Helpline yezilwane ze-antidote protocols ze-ethylene glycol toxicosis - I-American Animal Hospital Association (AAHA) imihlahlandlela yokunakekelwa okubucayi kwe-hypothermia - I-Canadian Veterinary Medical Association (CVMA) amakhodi ekheneli wokusebenza - I-Royal Society for the Prevention of Cruelty to Animals (RSPCA) amazinga asebusika ngaphansi kwe-Animal Welfare Act 2006 - Amazinga ase-Australia amakhodi ahambisana nawo kanye nenhlalakahle yezilwane esebenzayo
