Yin Chang-you, who is concurrently director of Chung Shan Hospital and also head of the anesthesiology department there, says that pain-free birth is very safe, and there is no effect on the infant. The only drawback is that, because delivery is painless, the mother is less likely to push as hard, thereby drawing out the delivery process.
中山醫院院長兼麻醉科主任殷長佑指出，無痛分娩的安全性極高，對胎兒也沒有什麼影響，唯一的缺點是由於產婦不痛，不會用力，因此會使產程變長。
