概括
在部分切除术期间长时间的温暖缺血会在30分钟后显著损害功能恢复. 低温可以提供保护,但对于患有孤独脏或慢性脏疾病的患者来说,避免长期温暖缺血是至关重要的.
科学领域:
- 腎臟病學 (nephrology) 是一種醫學.
- 泌尿器科 泌尿器科 泌尿器科 泌尿器科
- 手术创新 在外科创新.
背景情况:
- 部分切除术 (PN) 是对脏瘤的标准,但缺血时间对恢复的影响还未得到充分研究.
- 了解缺血的影响对于优化手术结果和保持功能至关重要.
- 长期缺血可能导致不可逆转的损伤,需要仔细的手术规划.
研究的目的:
- 为了评估长期缺血在上部分切除术 (PN) 期间的影响.
- 评估缺血持续时间,类型 (温暖与寒冷) 和功能恢复之间的关系.
- 确定长期缺血的门值,这些门值会显著影响术后脏结果.
主要方法:
- 追溯分析759名接受上PN (2011-2014) 的患者.
- 从缺血症 (Rec缺血症) 恢复的计算使用保存的ipsilateral GFR通过保存的辅酶体积 (PPVP) 正常化.
- 皮尔森相关性和多变量线性回归用于分析Rec缺血和缺血特征之间的关联.
主要成果:
- 平均热性缺血时间为22分钟,冷性缺血时间为30分钟;Rec缺血总体为96%.
- 在大约30分钟的温暖缺血症后,REC缺血症显著下降,但没有低温.
- 长时间的热性缺血 (>30分钟) 与减少的Rec缺血有关 (每10分钟减少3.9%超过30分钟).
结论:
- 在PN期间30分钟的热性缺血后,功能恢复 (Rec缺血症) 显著下降.
- 低温表明对缺血引起的损伤有保护作用.
- 优先避免长期温暖缺血症对于患有孤独脏或先前存在的慢性脏疾病的患者至关重要.

Methods of reducing fever
1.6K
The signs and symptoms of fever include hot and dry skin, flushed face, thirst, muscle aches, anorexia, headache, tachycardia, tachypnea, and fatigue. Elevated body temperature is reduced using two methods: pharmacological and nonpharmacological. Proper identification and treatment of the root cause of a fever is of utmost importance.

Decreased Body Temperature
1.2K
A decreased body temperature can occur in patients with hypothermia and frostbite. Heat loss with extended cold exposure overpowers the body's ability to create heat, resulting in hypothermia. Core temperature readings help classify hypothermia. Mild hypothermia is temperatures between 32 °C (89.6 °F) and 35°C (95 °F) and is caused by impaired thermoregulation. Moderate hypothermia is temperatures between 28 C (82.4 °F) and 32 °C (89.6 °F) caused by...
