Cold injury is a condition that causes reversible and irreversible damage when tissues are exposed to cold. This injury occurs due to various etiologies, and the most commonly observed ones include contact with liquefied petroleum gas (LPG) used in households, vehicles, and industry. LPG is a type of gas stored in liquid state under high pressure within cylinders. LPG contains a mixture of propane and butane gases. Direct contact of these gases with the tissues has the potential to cause metabolic, toxic, and respiratory damage. In this study, we present the cases of four patients with cold injury in the face and upper extremity caused by a pressurized jet stream of liquid gas that escaped out of the valves of the LPG cylinders. The patients had bullous lesions in the upper extremities and the face and second- and third-degree cold injuries with fibrotic and necrotic areas. The superficial defects secondarily healed with minimal scarring, while the necrotic finger had to be amputated. Cold injury on the skin caused by high-pressure jet streams of liquid gas as in our study is a rare occurrence. Our patients are important cases due to the rare etiology of cold injury.
冷损伤是一种当组织暴露于寒冷环境时会导致可逆和不可逆损伤的病症。这种损伤由多种病因引起，最常见的病因包括接触家用、车辆和工业中使用的液化石油气（LPG）。LPG是一种在气瓶内高压下以液态储存的气体。LPG包含丙烷和丁烷气体的混合物。这些气体与组织的直接接触有可能导致代谢、毒性和呼吸损伤。在本研究中，我们报告了4例因液化石油气瓶阀门逸出的液态气体加压喷射流导致面部和上肢冷损伤的病例。患者上肢和面部出现水疱性病变，伴有纤维化和坏死区域的二度和三度冷损伤。浅表缺损继发愈合，瘢痕 minimal，而坏死手指不得不截肢。如我们研究中所述，由液态气体高压喷射流引起的皮肤冷损伤很少见。由于冷损伤的病因罕见，我们的患者是重要病例。
