Dural puncture epidural technique provides better anesthesia quality in repeat cesarean delivery than epidural technique: Randomized controlled study

Table 3 Sensory nerve and motor block levels in the two groups at each time point after drug injection

	Group	5 min	10 min	15 min	20 min	5 min after operation
Sensory block levels of cranial side	EA (n = 57)	T11 (T10-11)	T9 (T7-T9)	T6 (T5-T7)	T5 (T4-T6)	T5 (T5-T6)

Values are expressed as median (interquartile range). The data were analyzed with linear mixed model. P_time: The time effect within group, the differences between the two groups at each timepoint were tested with adjusted bonferroni correction for multiple comparisons, P < 0.05 was considered statistically significant; P_group: The main effect between the epidural anesthesia and dural puncture epidural group over time; P_interaction: The interaction effect of group-by-time; CI: Confidence interval; DPE: Dural puncture epidural; EA: Epidural anesthesia.
