研究通讯作者、多伦多大学的 Mariana Bueno 指出，住院新生儿经常需要接受多次针刺，但并非每一次都会配套止痛或安抚措施，而年长儿童和成人几乎不会在没有任何镇痛的情况下接受类似处置。“证据表明，只需在操作前给予少量蔗糖，就能快速、有效地减轻疼痛，我们希望这份综述能让临床人员在使用这一方法时更有信心，也更愿意在实践中保持一致性。”她说。

A Riemannian metric on a smooth manifold \(M\) is a family of inner products \[g_p : T_pM \times T_pM \;\longrightarrow\; \mathbb{R}, \qquad p \in M,\] varying smoothly in \(p\), such that each \(g_p\) is symmetric and positive-definite. In local coordinates the metric is completely determined by its values on basis tangent vectors: \[g_{ij}(p) \;:=\; g_p\!\left(\frac{\partial}{\partial x^i}\bigg|_p,\; \frac{\partial}{\partial x^j}\bigg|_p\right), \qquad g_{ij} = g_{ji},\] with the matrix \((g_{ij}(p))\) positive-definite at every point. The length of a tangent vector \(v = \sum_i v^i \frac{\partial}{\partial x^i}\in T_pM\) is then \(\|v\|_g = \sqrt{\sum_{i,j} g_{ij}(p)\, v^i v^j}\).
