Abstract：Objective To investigate the effect of intraspinal anesthesia for labor analgesia at different puncture points on delivery process and maternal and neonatal outcomes.Methods A total of 120 parturients who underwent intraspi-nal anesthesia for labor analgesia and vaginal delivery from January 2022 to February 2024 were selected,and divided into high spinal anesthesia group(n=60)and low spinal anesthesia group(n=60)by random number table method.All parturi-ents in both groups received program-controlled epidural intermittent pulse injection+patient-controlled epidural analgesia.The high spinal anesthesia group received L1-2 intraspinal anesthesia,and the low spinal anesthesia group received L3-4 intraspi-nal anesthesia.Maternal blood loss,total duration of labor,anesthesia indexes,maternal delivery,neonatal outcomes and ad-verse reactions were compared between the two groups.Results There was no significant difference in maternal blood loss be-tween the two groups(P＞0.05).The total duration of labor in high spinal anesthesia group was shorter than that in low spi-nal anesthesia group(P＜0.05).The onset time of motor block,sensory block and sensory recovery time in high spinal anes-thesia group were shorter than those in low spinal anesthesia group,and the number of anesthesia block ganglia was significant-ly reduced,as compared with low spinal anesthesia group(P＜0.05).The first and second stages of labor in high spinal an-esthesia group were shorter than those in low spinal anesthesia group(P＜0.05).There was no significant difference in cesar-ean section rate,vaginal midwifery rate and vaginal delivery rate between the two groups(P＞0.05).The Apgar score at 1 and 5 min after birth in the high spinal anesthesia group was higher than that in the low spinal anesthesia group(P＜0.05).The total incidence of adverse reactions was 8.33%(5/60)in the high spinal anesthesia group and 10.00%(6/60)in the low spinal anesthesia group,and there was no significant difference between the two groups(P＞0.05).Conclusion L1-2 in-traspinal anesthesia has a good effect on labor analgesia,which can shorten delivery process,improve neonatal Apgar score,and does not significantly increase adverse reactions.
