Abstract Objective To compare the effects of two kinds of intraspinal block anesthesia on body temperature during different periods of labor in patients with latent labor analgesia. Methods From June 2017 to July 2018, 240 eligible pregnant who was the first-time mothers in Heibei Petroleum Center Hospital were selected, according to the random number table method, they were randomly divided into continuous epidural block and analgesia group (group A), combined lumbar stiffness block and analgesia group (group B) and no labor analgesia group (group C), 80 cases in each group. Patients in group A were given continuous epidural block anesthesia when the uterine opening was 1-2 cm, and 0.1% Ropivacaine Hydrochloride was given 8 mL. After 30 min, the epidural catheter was connected with the automatic electronic analgesic pump (the electronic pump was equipped with 0.1% Ropivacaine Hydrochloride and 0.5 μg/mL mixed solution of Sufentanil 100 mL). Patients in group B were treated with lumbar hard combined block anesthesia when the uterine opening was 1-2 cm, followed by subarachnoid injection of 0.1% Ropivacaine 3 mg. After 30 minutes, the epidural catheter was connected with the automatic electronic pump. Group C was in normal delivery. Withdrawing the labor analgesia when the delivery was ending. The maternal temperature was measured at the time of delivery, the temperature at 2 cm of the uterine opening, the temperature at 4 cm of the uterine opening, the temperature at the full time of the uterine opening, and the temperature at 2 h and 24 h after the delivery in three groups. All parturients were tested for CRP and WBC by venous blood sampling before and after 24 h. Results The fever rate of ＞37.3℃ in group A and group B was significantly higher than that in group C, and the difference was statistically significant (P ＜ 0.05). Postpartum CRP levels of three groups were higher than those of prenatal women, and the levels of postpartum CRP in group A and group B were higher than those in group C, the differences were statistically significant (P ＜ 0.05). Conclusion Both kinds of intraspinal anesthesia can cause the rise of body temperature during childbirth, but it can return to normal 24 h after delivery. The increase of body temperature has little relationship with infection.
