Ta main poser sur mon genoux et moi la recouvre avec la mienne me fait dire que malgré l’épreuve difficile j’ai la chance de t’avoir rencontré, nous n’avons aucun lien de sang ni rien mise à part celui de l’amour. Je remercie Dieu de m’avoir offert ce que j’ai toujours voulu avoir une famille , un père. Je serais toujours là ou tu seras , je ne t’abandonnerais pas. Qu’est ce que j’ai pu pleurer mais tu es ma force et tu redresses ma tête quand je commence à la baisser. Je t’es enfin trouver et crois moi je te lâcherai plus ❤️ #family#familygoals#hospital#maladie#force#merci#thegiftoflife#thefatherofgod#nevergiveup#loveyou#somuchlove#thanksgod#thankslife
Whoops, frostbite in a 21-year-old patient resulting in amputation!
Frostbite is still a problem on the rising. Many alcoholics are victims, having fallen asleep in a snowbank, a car, or an abandoned garage.
This patient sustained grade IV frostbite injuries to both feet after sleeping out in sub-zero temperatures.
Gangrene denotes the death of tissue, which results from the gradual loss of blood supply to a part of the body. The tissue slowly dies because it receives little or no oxygen and nutrients from the blood, but it does not become infected (i.e. In cases of wet gangrene).
The nature of frostbite has been highly controversial. Until recently, it was believed that it was a direct thermal injury to the tissue. Others believed the indirect injury resulted from changes in the microcirculation. Now it appears that both mechanisms are important. Cold can destroy tissue directly by forming intracellular ice crystals or more commonly by interstitial freezing with consequent extraction of water from the cells. But the blood supply to the frozen area also undergoes profound changes.
Frostbite causes tortuous dilatation of the small vessels, as well as occlusions and intravascular tubular filling defects. Vascular stasis follows, causing ischemia and subsequent tissue necrosis and gangrene.
The very first symptoms experienced are numbness and tingling sensation in the affected area.
In cases such as the one shown, the severity of tissue damage depends upon the degree and the duration of cold. Thus, wind, wetness, contact with metal, or anything that speeds heat loss increases the danger to exposed parts of the body.
The frostbitten limb undergoes acute changes within hours and in situations like this, amputation is done to prevent progression.
