Abstract:
Objective: To explore relation of pain threshold and effect of labor analgesia with Anxiety in Nulliparous. Methods: The psychosis according to Hamilton Anxiety Scale(HAS) and Hamihon Depression Scale(HDS) were evaluated in 50 primiparae requiring epidural labor analgesia. The cases were divided into two groups the experiment group subdivided into exp I(24 cases with mild anxiety) and exp H(9 cases with moderate to severe anxiety) and the control group(19 cases without anxiety) There was no Nulliparous with depression(HDS, scores<8) The effect of analgesia the labor course the mod e of delivery the plasma concentrations of epinephrine (E), norepinephrine(NE) and β-EP in the two groups were observed Results: The rate of anxiety in 50 nulliparous was 66 In the experimental group the epidural labor analgesia was weak the degree of nulliparous anxiety was less the latent time prolonged the E level elevated and NE levels lowered as compared with the control(P<0 01), the changes of PPT was significantly negatively correlated to the HAS score(P<0 005) Conclusion: The degree of nulliparous anxiety descrease the pain threshold and influences the effect of the epidural labor analgesia Therefore it is necessary to estimate fully the degree of nulliparous anxiety before delivery and to take individual and to improve the obstetrics quality.
