Abstract:

Objective: To explore the adjuvant effect of intradermal needle combined with wristankle acupuncture under the concept of preemptive analgesia in patients undergoing fiberoptic bronchoscopy. Methods: A total of 120 patients undergoing fiberoptic bronchoscopy in the Department of Respiratory and Critical Care Medicine, Foshan Second People’s Hospital from January to July 2023 were enrolled. They were randomly divided into treatment group, control group, and sham acupuncture group, with 40 cases in each group. Vital signs, Selfrating Anxiety Scale (SAS) scores, patient comfort (Visual Analogue Scale 1, VAS1), physician satisfaction (Visual Analogue Scale 2, VAS2), and postoperative adverse reactions were compared at four time points: before examination (T1), passing the glottis (T2), 5 minutes after passing the glottis (T3), and after completion of examination (T4). Results: Repeatedmeasures analysis of variance showed significant differences in systolic blood pressure among the three groups (F=4.130, P=0.019). Systolic blood pressure in the treatment group at T3 and T4 ((132.51±15.47) mmHg and (131.20±17.69) mmHg; 1 mmHg=0.133 kPa) was more stable than that in the control group ((135.05±18.57) mmHg and (136.88±19.33) mmHg) and sham group ((141.73±16.82) mmHg and (145.45±21.02) mmHg). Heart rate also differed significantly among groups at all time points (F=3.850, P=0.024). SAS scores decreased significantly in the treatment group after examination (42.61±8.49 vs. 40.95±6.42; t=2.010, P=0.050), but increased markedly in the control and sham groups. VAS1 and VAS2 scores remained stable in the treatment group but decreased significantly in the other two groups. The incidence of adverse reactions in the treatment group was 10.0% (4/40), significantly lower than 42.5% (17/40) in the control group and 32.5% (13/40) in the sham group (χ²=10.917, P=0.004). Conclusion: Intradermal needle combined with wristankle acupuncture can stabilize vital signs, relieve anxiety, improve patient comfort and physician satisfaction, and reduce adverse reactions in patients undergoing fiberoptic bronchoscopy.
