[Auxiliary analgesic effect of wrist-ankle acupuncture on patients undergoing transforaminal endoscope surgery]

To observe the auxiliary analgesic effect of wrist-ankle acupuncture on patients undergoing transforaminal endoscope surgery.

A total of 64 patients with lumbar disc herniation who underwent percutaneous lateral transforaminal endoscope surgery were randomly divided into an observation group and a control group, 32 cases in each group. The patients in the control group were treated with injection of 1% lidocaine for routine local infiltration anesthesia. The patients in the observation group were treated with wrist-ankle acupuncture at lower 5 area and lower 6 area for 30 min, 5 min before routine local infiltration anesthesia; immediately, 15 min, 30 min after insertion the left-right technique, up-down technique, and rotation technique were applied for six times, respectively. The mean arterial pressure (MAP), heart rate (HR), blood oxygen saturation (SpO₂) and pain visual analogue scale (VAS) were compared between the two groups at the time points of intraoperative puncture (T₁), circular saw grinding (T₂), and placement of working channel (T₃). The intention of reoperation was recorded immediately after operation and 24 h after operation. The expectation and treatment credibility scale (ETCS) was used to evaluate the relationship between patients' expectation and efficacy 5 min before operation and immediately after operation.

At T₂ and T₃ during the operation, the MAP and HR in the obserrvation group were lower than those in the control group, while SpO₂ was higher than that in the control group (P<0.05). At T₁, there was no significant difference of MAP, HR and SpO₂ between the two groups (P>0.05). At T₂, the peak VAS and average VAS in the observation group were lower than those in the control group (P<0.05), but there was no significant difference at T₁ and T₃ (P>0.05). The intention of reoperation in the observation group was higher than that in the control group both immediately after operation and 24 h after operation (P<0.05). In the observation group, the scores of each item in ETCS immediately after operation were higher than those 5 min before operation (P<0.05), while in the control group there was no significant difference between immediately after operation and 5 min before operation (P>0.05). The scores of ETCS1, ETCS2 and ETCS3 immediately after operation in the observation group were higher than those in the control group (P<0.05).

The wrist-ankle acupuncture has positive auxiliary analgesic effect on lumbago during transforaminal endoscope surgery, and strengthens the patients' confidence on the operation effect.
