[Influence of acupuncture-drug compound anesthesia with different frequency electroacupuncture on immune function in patients undergoing pneumonectomy].

OBJECTIVE:
To explore different frequency electroacupuncture in acupuncture-drug compound anesthesia on analgesic effect and immune function in the pulmonary resection patients in order to recommend the best electroacupuncture frequency in acupuncture-drug compound anesthesia.
METHODS:
One hundred and sixty-three patients scheduled for pneumonectomy were randomly divided into group A (n = 31), B (n = 34), C (n = 32), D (n = 34) and E (n = 32). Houxi (SI 3), Zhigou (TE 6), Neiguan (PC 6) and Hegu (LI 4) were selected in the five groups. Group A was treated with sham acupuncture by pasting needles without needle bodies at acupoints and electroacupuncture at the needle handle, and group B with 2 Hz electroacupuncture, and group C with 2 Hz/ 100 Hz electroacupuncture, and group D with 100 Hz electroacupuncture, and group E with 2 Hz/100 Hz transcetaneous acupoints electrical stimulation, and general anesthesia was produced in all the groups followed by 30 min electrical stimulation and the stimulation was lasted till the end of operation. The dosages of the anesthetics and the changes of surface antigen of leukomonocyte (CD3+ , CD4+ , CD8+ and CD4+/CD8+) and natural killer (NK) cell were observed at 1 day before surgery, intraoperative and 1 day after surgery.
RESULTS:
In comparison with group A, the dosages of Propofol in group B and D were decreased, Fentanyl in group B, D and E were decreased. CD3+ and CD4+ in 5 groups increased at first and then decreased over time (all P < 0.01), and group E and C could inhibit the decrease of CD3+ and CD4+ in postoperation in comparison with that in the other three groups (all P < 0.05). CD8+ in 5 groups has no change in different times (all P > 0.05), and group E and D could inhibit the decrease of CD8+ in postoperation in comparison with that in the other three groups (all P < 0.05). CD4+/CD8+ in 5 groups has no change in different times (all P > 0.05), and group E and C could inhibit the decrease of CD4+/CD8+ in postoperation in comparison with that in the other three groups (all P < 0.05). NK cells of 5 groups were increased gradually in different times (all P < 0.01), with the similar regulation of NK cells (all P > 0.05).
CONCLUSION:
Acupuncture-drug compound anesthesia with 2 Hz and 100 Hz electroacupuncture together with 2 Hz/100 Hz transcetaneous acupoints electrical stimulation have the best analgesic effect, and 2 Hz/100 Hz transcetaneous acupoints electrical stimulation and 2 Hz/100 Hz electroacupuncture have the best regulation of immune function. Acupuncture-drug compound anesthesia with 2 Hz/100 Hz transcetaneous acupoints electrical stimulation is recommended for that it can not only decrease the dosages of the anesthetics, but also significantly improve the immunosuppression in patients undergoing pneumonectomy.
