What are the side effects of painless childbirth?

Epidural analgesia is highly effective in relieving labor pain, but it may also be associated with some side effects, mainly including: 1. Hypotension: Some women may experience a drop in blood pressure during epidural analgesia, which requires close monitoring. 2. Headache: A puncture during spinal anesthesia may accidentally breach the dura mater, leading to headache, particularly exacerbated when sitting or standing, although it usually resolves spontaneously. 3. Nausea and vomiting: Some women may experience symptoms of nausea and vomiting after labor analgesia. 4. Prolonged labor: Analgesia may reduce the sensation of pain, thereby affecting the speed and strength of labor, leading to prolonged labor. 5. Allergic reaction: A very small number of women may develop an allergic reaction to the drugs used for labor analgesia. 6. Back pain: Spinal anesthesia may cause nerve damage, resulting in back pain, although the incidence is low.
