Objective: To observe the effect of wrist-ankle acupuncture on the incidence of hypertension after tracheal intubation during induction of general anesthesia.
Methods: 200 patients receiving selective surgery under tracheal intubation and general anesthesia in our Hospital were selected and divided into control group and wrist-ankle acupuncture group using the random number table method, with 100 patients in each group. Sufentanil, cisatracurium besilate, remifentanil, etomidate and lidocaine hydrochloride were used for anesthesia induction, and intravenously injected according to the onset time of drugs, successively. The wrist-ankle acupuncture group was needled in bilateral upper 1, 2 and 3 areas, while the control group was treated with false acupuncture.Blood pressure and related blood biochemical indexes were measured and observed at different stages in each group.
Result: The incidence of blood pressure exceeding 20% and 30% of basal blood pressure within 5 minutes after intubation was as follows:wrist-ankle acupuncture group 11.83% and 6.45%; control group 29.79% and 22.34%, The incidence in the study group was lower than that in the control group. Norepinephrine concentration in the wrist-ankle acupuncture group was significantly lower than that before induction (P < .05), and plasma Norepinephrine concentration in the wrist-ankle acupuncture group was significantly lower than that in the control group after intubation (P < .05). The plasma Norepinephrine concentration in the wrist-ankle acupuncture group was significantly lower than that in the control group after intubation (P < .05).
Conclusion: wrist-ankle acupuncture can prevent hypertension after intubation during anesthesia induction. Moreover, it is safe, effective, minimally invasive. Therefore, it is easy to be popularized in clinical practice.
