鼻血警號 Nose Bleed

秋冬季節,天氣乾燥,小朋友和長者比平日更容易流鼻血。有醫生指出,臨牀上每逢天氣轉冷的時間,就會比平日多50%人因為流鼻血而求診。一般而言,流鼻血只屬正常生理反應,但如果經常發生就應該小心處理,有可能是身體出現毛病的警號。

耳鼻喉科專科醫生林建業(圖)指,每到11月至12月不少兒童和長者都會因流鼻血求診。長者與兒童流鼻血的原因都不同,小朋友因為鼻內的血管較幼,容易破損。而長者主要因為血管硬化引起,服用薄血藥等藥物者,亦會較易流鼻血。

林建業表示,多數流鼻血屬正常情況,不會影響健康,但一些情況如鼻竇癌、鼻咽癌和血管瘤等疾病,都會導致流鼻血;如果一般人在沒有受到撞擊情況下,一個月只流鼻血一次,每次數滴血就不需擔心,一旦每星期流血幾次就要注意,需要向醫生求醫。

他提醒市民,流鼻血時,不要躺下,應用拇指和食指按住鼻翼和鼻中骨,連續按住約5至10分鐘就能止血,如果非連續按住,會影響止血效果,一旦流血不停就要叫救護車。如果病人經常有流鼻血問題,醫生會使用「電烙」方法,將經常破損的血管封住。

The most common cause of anterior nosebleeds is dry air. A dry climate or heated indoor air irritates and dries out nasal membranes, causing crusts that may itch and then bleed when scratched or picked. Colds also may irritate the lining of the nose, and bleeding can occur after repeated nose-blowing. When you combine a cold with dry winter air, you have the perfect formula for nosebleeds.

What to do with nose bleeds? Keep pressure on the nose for about 10 minutes; if you stop too soon, bleeding may start again. DO NOT lean back. This may cause blood to flow down the back of the throat, which tastes bad and may cause gagging, coughing, or vomiting.

Nosebleeds are rarely cause for alarm, but frequent nosebleeds might indicate a more serious problem. If you gets nosebleeds more than once a week, you should contact your doctor.
