側睡可以降低孕婦死產的機率 (轉自紐約時報)

在菩提格訓練課程中,我們除了要求在睡眠中嘴巴要閉起來以外,另外強調的就是側睡。除了因為側睡可以幫助減緩我們呼吸的幅度,讓我們身心更放鬆,側睡其實還有許多其他的好處。以下這篇摘自紐約時報的報導就是講解側睡對於懷孕婦女的幫助。

一個新的研究指出,在落後國家的婦女在經過指導側著身子睡覺以後,許多的死產是可以避免的。

一位碩士生的研究中,訪問了220位在迦南一家醫院剛生產完的孕婦,有關他們懷孕期間睡覺的習慣。

美國密西根州立大學睡眠中心的 O’Brien教授指出,由於迦南的死產率很高,這項研究對於較貧窮的國家意義甚大,單單靠著在懷孕時盡量的側睡,就可以減少百分之25的死產率。

這項研究在上個月被刊登於國際婦產科醫學會期刊,研究同時也發現,睡覺時鼾聲大的孕婦 (通常是因為仰臥而造成的),很容易會有高血壓 (妊娠型高血壓),進而造成妊娠毒血症 (又稱產前子癇症),如果疏忽的話很有可能會讓母親及胎兒一同死亡。

這篇迦南的研究結果與許多其他的來自美國、紐西蘭的研究結果不謀而合。O’Brien教授指出,孕婦如果患有睡眠呼吸中止症的話會造成血壓升高並對胎兒造成危險。

The leading theory, she said, is that when a heavily pregnant woman sleeps on her back, the uterus compresses the vena cava, the blood vessel going up the spine that returns blood to the heart. That starves the fetus, leading to smaller babies and more stillbirths. Supine sleeping also closes the airways, leading to oxygen deprivation, which raises blood pressure. Closed airways lead to snoring.

“In the delivery room, when an obstetrician sees a baby in distress, they often flip the woman on to her side,” Dr. O’Brien said. “But people haven’t thought through the connection to the months prior to delivery.”

In wealthy countries, blood pressure is lowered with drugs and apnea is prevented with breathing machines. But the drugs are little used in Africa and the machines are too costly.

In the days before breathing machines, people with apnea sometimes sewed tennis balls to the back of their pajamas to prevent supine sleeping, Dr. O’Brien said, so some sort of similar low-tech treatment might be useful in poor countries.
