頭痛是脊髓麻醉術後常見的併發症之，並影響病人術後的舒適感。臨床上醫護人員均常規性衛教病人術後臥床平躺6至8小時，以預防發生頭痛。然而，術後臥床真的能預防頭痛嗎？本文之目的係以實證醫學關點探討脊髓麻醉術後病人常規性臥床對預防頭痛的效果。搜尋的資料庫有PubMed，Cochrane Library，中文電子期刊服務網，利用布林邏輯、醫學主題詞表及關鍵字進行文獻搜尋。最後選入篇符合臨床情境之系統性文獻回顧，其收錄11篇隨機對照試驗研究，共納入1723位病人。研究分析結果發現脊髓麻醉術後臥床或早期活動對病人頭痛的發生無顯著差異。病人接受脊髓麻醉後常規性臥床未能降低姿勢性頭痛的發生，對病人而言無顯著之益處。

The objective of this article was to explored the efficacy of routine bed rest to prevent post-dural puncture headache. A systemic literature search of PubMed, The Cochrane Library, and the Chinese Electronic Periodical Service.

It included eleven trails among 1723 patients compared either bed rest with immediate mobilization. Routine bed rest after dural puncture does not prevent headache.
