RESUMO
Objective:To explore the effect of intraspinal labor analgesia on labor progress, maternal and infant outcomes.Methods:Two hundred cases of full-term singleton primiparous women in head position admitted to the Second Affiliated Hospital of Shantou University Medical College from March 2019 to March 2020 were selected as the research subjects. According to the random number table method, they were divided into the control group (100 cases, natural delivery) and the analgesia group (100 cases, analgesia delivery). The visual analoguescore (VAS), progress of labor, and the outcome of delivery between the two groups werecompared.Results:The VAS scores of the analgesic group at 10, 30 and 60 min after analgesia were lower than those in the control group: (1.30 ± 0.17) scores vs. (9.50 ± 0.53) scores, (0.50 ± 0.22) scores vs. (9.50 ± 0.16) scores, (0.40 ± 0.28) scores vs. (9.50 ± 0.34) scores, the differences were statistically significant ( P<0.05). The first stage of labor in the analgesia group was longer than that in the control group: (347.6 ± 54.4) min vs. (325.8 ± 58.5) min; but the active stage, the second stage of labor, the third stage of labor and the total duration of labor in the analgesia group were shorter than those in the control group: (184.3 ± 39.5) min vs. (202.9 ± 42.7) min, (57.8 ± 17.9) min vs. (85.3 ± 16.9) min, (7.7 ± 5.0) min vs. (16.3 ± 5.2) min, (503.6 ± 131.4) min vs. (596.5 ± 175.7) min, the differences were statistically significant ( P<0.05). The 2 h and 24 h postpartum hemorrhage in the analgesia group were significantly lower than those in the control group: (223.64 ± 80.34) ml vs. (276.97 ± 82.35) ml, (331.57 ± 92.47) ml vs. (384.59 ± 94.25) ml, the differences were statistically significant ( P<0.05). The rate of normal delivery and the use of oxytocin in the analgesia group were higher than those in the control group: 91.0%(91/100) vs. 75.0%(75/100), 83.0%(83/100) vs. 49.0% (49/100), the differences were statistically significant ( P<0.05). In the newborn Apgar scores, the muscle tension, pulse, reflex response, respiration score and total score in the analgesia group were significantly higher than those in the control group ( P<0.05). The neonatal distress in the analgesia group was lower than that in the control group: 4.0%(4/100) vs. 15.0%(15/100), the difference was statistically significant ( P<0.05). Conclusions:Intravertebral labor analgesia can shorten the time of parturient delivery, reduce postpartum hemorrhage, improve the Apgar score of newborns, increase the pregnancy rate, and improve maternal and infant outcome.
