Pregnancy &Low Platelets

血小板減少症、または低血小板数は、妊娠または妊娠中に発生する既存の状態になる可能性があります。英国の助産アーカイブによると、妊婦の5〜7％が血小板数が少ないことに苦しんでいます。 Often the condition is mild, and normal platelet counts return after birth.

1. 識別

   • 血小板数が妊娠中にわずかに低下するのは正常ですが、血小板数が血液1マイクロリットルあたり150,000血小板を下回ると、妊娠中の女性が血小板減少症と診断される可能性があります。 Sometimes symptoms aren't even noticed until the platelet count falls below 50,000. Normal platelet counts are 150,000 to 400,000 platelets per microliter.血小板障害支援協会は、妊娠中は10％の血小板が正常であり、この小さな減少は血小板減少症につながっていないと述べています。

   重要性

   • Formed in the bone marrow, platelets are small, sticky components of blood. According to the Platelet Disorder Support Association, platelets maintain the integrity of blood vessels. These platelets help to seal cuts and help to heal wounds by forming clots. Without a normal number of platelets, wounds cannot clot as quickly, and excessive bleeding could result.

   症状

   • For mild cases of low platelet counts in pregnancy, the UK Midwifery Archives states that often an affected pregnant woman won't experience any symptoms.しかし、より深刻な症例については、血小板障害支援協会は、症状には自発的な打撲傷または植物が含まれていると述べています。

     Low platelet counts can cause excessive bleeding. Bleeding such as blood blisters on the inside of cheeks, or even blood in urine or stool can occur with low counts. The Platelet Disorder Support Association says that extremely low platelet counts can lead to cerebral hemorrhage, bleeding on the brain.

   原因

   • The causes for thrombocytopenia aren't thoroughly understood. Pregnancy-induced thrombocytopenia may be linked to hypertension or preeclampsia in pregnancy when platelet levels fall below 100,000.

     一部の女性にとっては、通常妊娠に伴う低血小板は、女性が以前は気づいていなかった慢性的な問題を明らかにするかもしれません。 Immune thrombocytopenic pupura (ITP) is an auto-immune disease and causes the body to attack one or more of its organ systems. Platelets can become a target, and the body eliminates them through the spleen or liver.

   治療

   • For mild cases, no treatment is necessary, and platelets should return to normal levels after birth. For severe symptoms, the Merck Manuals Online Medical Library recommends bed rest to avoid accidental injury and excessive bleeding.また、出血が重度である場合、血小板を輸送できると書かれています。
