Also, low levels of vitamin D can also lead to hypocalcemia, and can be caused by a deficient diet, malabsorption, cirrhosis, a lack of sunlight, and chronic renal failure, just to name a few.

此外，维生素D含量过低也会导致低钙，可能由饮食中的维生素D不足、吸收不良、肝硬化、缺乏日照与慢性肾衰竭等所致。

In addition to general symptoms like nausea and vomiting, another distinctive sign of acute pancreatitis is hypocalcemia, particularly when there is a lot of fat necrosis because that process tends to consume calcium.

除了恶心、呕吐等一般状外，急性胰腺炎的另一个显着标志低钙，特别当有很多脂肪坏死时，为这一过程往往会消耗钙。

This is therefore called false hypocalcemia or pseudohypocalcemia, since there's less overall calcium due to less bound calcium, but the free ionized calcium levels are still the same.

这就被称作假性低钙，为总钙为结合钙，游离钙水平仍然不变。

And so even though the total levels of calcium are the same, there's less ionized calcium which is the one that's important for cellular processes and can lead to symptoms of hypocalcemia.

此，即使钙的总含量相同，游离钙了，它对细胞过程很重要，会产生低钙的状。

This can trigger tetany or the involuntary contraction of muscles, a classic symptom of hypocalcemia.

这会触发手足抽搐或肌肉非自主收缩，这低钙的典型状。

Alright, as a quick recap, hypocalcemia describes a low concentration of free ionized calcium in the blood, which most commonly results from defective production of calcium controlling hormones, like parathyroid hormone and active vitamin D.

得！快速回顾一下：低钙意味着液中游离离子钙的浓度低，最常见的原钙调控激素如甲状旁腺激素和活性维生素D的生成出现问题。

In hypocalcemia, the main goal is to normalize calcium levels using formulation like calcium gluconate, and if appropriate, vitamin D supplementation.

在低钙的治疗中，主要目标使钙水平正常化，比如使用葡萄糖酸钙这类制剂，并在适当时补充维生素D。

Acute hypocalcemia should be treated promptly with intravenous calcium.

急性低钙应及时静脉补钙治疗。

The nurse can elicit Trousseau's sign by occluding the brachial or radial artery. Hand and finger spasms that occur during occlusion indicate Trousseau's sign and suggest hypocalcemia.

护士可以通过阻断肱动脉或桡动脉来引出特鲁索(氏)征。阻断期间手和手指痉挛则为特鲁索(氏)征并提示低钙。

Other causes of hypocalcemia include low vitamin D intake or production, and excessive loss of calcium from the circulation such as in kidney diseases, tissue injuries, or gastrointestinal diseases.

低钙的其他原包括维生素D摄入或产生量低，以及循环系统中钙过度流失，如肾脏疾病、组织损伤或胃肠道疾病。

Most symptoms of acute hypocalcemia can be attributed to the effect, it has on action potential generation in neurons.

急性低钙的大多数状可归于其对神经元动作电位产生的影响。

Effects of hypocalcemia on cardiac function include long QT interval due to prolonged ST segment, congestive heart failure, and hypotension.

ST段延长引起的QT间期延长、充性心力衰竭和低压。

The most common cause of hypocalcemia is PTH deficiency, resulting from decreased function of the parathyroid glands or hypoparathyroidism.

低钙最常见的原甲状旁腺功能降低或甲状旁腺功能低下引起的PTH缺乏。

Hypocalcemia refers to abnormally low levels of calcium in the blood and is generally defined as serum calcium level lower than 2.1 millimoles per liter.

低钙指液中钙含量异常低，通常定义为清钙含量低于2。1mmol/L。

While chronic moderate hypocalcemia may be asymptomatic.

而慢性中度低钙可能无状。
