一项最新研究发现，较低的维生素D水平可能导致分娩更加疼痛。本周四在美国新奥尔良举行的美国麻醉医师学会年会上，作者进行了相关报告。
据美国妇产科医师学会介绍，妊娠期间的维生素D缺乏是较为常见的，特别是以下高危孕妇：素食者、较少晒太阳和少数族裔。
这项研究共纳入93名孕妇，生产前均接受维生素D水平测定，且分娩过程中均接受了硬膜外麻醉。随后，研究人员对分娩过程中的麻醉药物总用量进行了记录。他们发现，对于维生素D水平较低的产妇，术中的麻醉药物用量明显更多。
本研究的作者，来自美国洛杉矶西德斯西奈医学中心的Dr.AndrewGeller说：“怀孕期间的维生素D水平下降是非常常见的。我们发现，这些产妇所经历的分娩疼痛明显更多。因此，如果对维生素D缺乏的孕妇进行全面预防和治疗，有望显著缓解分娩期间的剧烈疼痛。”
Geller补充道：“我们仍需要进行更多的研究，以积极改善分娩过程中的方方面面。”

Low vitamin D levels could make childbirth more painful, according to a new study.
Vitamin D deficiency is common during pregnancy, especially among high-risk women, including vegetarians, those with little sun exposure, and members of ethnic minorities, the American College of Obstetricians and Gynecologists says.
The new study included 93 pregnant women whose vitamin D levels were checked before childbirth and who received an epidural for pain during labor. The researchers measured how much pain medication each of the women required during delivery.
Women with lower vitamin D levels required more pain medication than those with higher vitamin D levels, according to the study scheduled for presentation Tuesday at the annual meeting of the American Society of Anesthesiologists in New Orleans.
"Women often experience lower than normal levels of vitamin D during pregnancy. We found that patients with low levels of vitamin D experienced an increase in pain during childbirth," senior author Dr. Andrew Geller, an anesthesiologist at Cedars-Sinai Medical Center in Los Angeles, said in a society news release.
"Given the research results, prevention and treatment of low vitamin D levels in pregnant women may have a significant impact on decreasing labor pain in millions of women every year," he added.
"This topic needs to be revisited and additional research should be conducted to determine how we can improve the labor experience for women everywhere," Geller concluded.
Studies presented at meetings are usually considered preliminary until published in a peer-reviewed medical journal.
