Pulse examination, which reveals information about bodily qi and blood circulation, is an essential diagnostic tool in traditional Chinese medicine. Capillary refill time (CRT) is a simple test parameter for assessing circulation status. Examining the root of pulse and measuring CRT are extremely similar procedures. The objective of this study was to evaluate the effect of acupuncture on CRT.
Three acupoints were selected to evaluate the effects of CRT. CRT, quantitative CRT, heart rate, core body temperature, and blood pressure were measured before acupuncture and immediately after removal of needles and 30 min after removal of needles. A total of 15 healthy adults representing both sexes were prospectively included in the study. The acupoints selected were bilateral Taixi (KI3), Hegu (LI4), and Zusanli (ST36). Each participant received acupuncture three times, interventions were separated by at least 2 days, and acupuncture was performed on only one acupoint at each intervention.
CRT decreased significantly after acupuncture on only KI3. Quantitative CRT decreased significantly after acupuncture on KI3 and LI4. Heart rate changed significantly after acupuncture on KI3 and ST36.
Acupuncture on KI3 can reduce CRT in health adults.
脉象反映了人体气血运行的信息，是中医重要的诊断工具。毛细血管再充盈时间（CRT）是评估循环状态的简单测试参数。切脉和测量 CRT 非常相似。本研究旨在评估针刺对 CRT 的影响。
选择三个穴位来评估 CRT 的影响。在针刺前、针刺后立即和针刺后 30 分钟测量 CRT、定量 CRT、心率、核心体温和血压。共有 15 名健康成年人（男女各半）前瞻性纳入研究。所选穴位为双侧太溪（KI3）、合谷（LI4）和足三里（ST36）。每个参与者接受 3 次针刺，干预措施至少间隔 2 天，每次干预仅针刺一个穴位。
仅针刺 KI3 后 CRT 明显降低。针刺 KI3 和 LI4 后定量 CRT 明显降低。针刺 KI3 和 ST36 后心率明显改变。
针刺 KI3 可降低健康成年人的 CRT。
