[Effect of acupoint application therapy at different timing points on gastrointestinal function recovery and heart rate variability after laparoscopic resection of colorectal cancer].

Objective: To observe the effect of acupoint application therapy at different timing points on the gastrointestinal function recovery and heart rate variability (HRV) after laparoscopic resection of colorectal cancer under the instruction of enhanced recovery after surgery (ERAS).

Methods: A total of 105 patients for the selective laparoscopic resection of colorectal cancer were selected and randomized into a preoperative acupoint application group (35 cases, 3 cases dropped off), a postoperative acupoint application group (35 cases, 1 case dropped out) and a control group (35 cases, 2 cases dropped off). In the control group, ERAS interventions were provided, such as health education, fluid supplementation and multi-mode analgesia.
