背景:在妊娠期間使用阿斯匹林可能對於妊娠結局具有影響。 方法:使用實證醫學的步驟,搜集彙整文獻並加以評讀後挑出有品質的研究進行統合分析。所使用的資料庫包括PubMed(1966-2013)、EMBASE(1980-2013)TOXLINE (1994-2013),EB M Cochrane Database of Systematic Reviews (1991-2013),使用阿斯匹林(aspirin)和水楊酸(salicylic acid)作為關鍵字尋找符合主題的隨機對照試驗研究(randomized controlled trials)進行評讀,將評讀後的研究進行統合分析(meta-analysis)。 結果:共有44項研究納入分析,個別提取其研究的數值進行統合分析得知結果。在隨機效應模式(random effect model)觀察到阿斯匹林和安慰劑的使用對於流產的危險沒有顯著差異(9項研究;RR,0.96;95% CI, 0.76– 1.22);但在早產的危險中則具有顯著差異(23項研究;RR,0.88;95% CI, 0.81– 0.96)。此外,在週產期死亡的危險中阿斯匹林和安慰劑的使用沒有顯著差異(16項研究;RR,0.93;95% CI, 0.80– 1.07);同樣地,在胎兒小於妊娠年齡(SGA)的危險中,阿斯匹林和安慰劑的使用沒有顯著差異(16項研究;RR,0.88;95% CI, 0.74– 1.06)。 結論:在妊娠期間,使用阿斯匹林對於早產有顯著降低危險的效果;不過在流產、週產期死亡、胎兒小於妊娠年齡(SGA)、Apgar分數則沒有顯著的效果。
BACKGROUND: Assessed the effects of aspirin use on pregnant mothers, their fetuses, and on the pregnancy outcomes. METHODS: Used the keywords aspirin and salicylic acid to search for articles in PubMed (1966-2013), EMBASE (1980-2013), TOXLINE (1994-2013), EBM Cochrane Database of Systematic Reviews (1991-2013), All articles were reviewed and selected for meta-analysis. RESULTS: Data from pooled from 44 studies and analyzed. Under the random effect model, the risk of miscarriage did not show significant association to both aspirin and placebo use (9 studies; RR,0.96;95% CI, 0.76–1.22). The risk of preterm delivery showed significant association to both aspirin and placebo use (23 studies; RR,0.88;95% CI, 0.81– 0.96). The risk of perinatal mortality did not show significant difference between aspirin and placebo use (16 studies; RR,0.93;95% CI, 0.80– 1.07). The risk of small-for-gestational-age infants did not show significant association to both aspirin and placebo use (16 studies; RR, 0.88;95% CI, 0.74– 1.06) CONCLUSION: Aspirin use during gestation decrease the risk of preterm delivery, but has no effect on miscarriage, perinatal mortality and small-for-gestational-age infants.
