Comparative efficacy of hyperbaric bupivacaine vs hyperbaric ropivacaine in spinal anesthesia for cesarean section: A meta-analysis

Table 2 Results for continuous variable

Parameter	Standardized mean difference	95%CI	P value	I²	Interpretation
Onset of sensory blockade	1.07	-0.73 to 2.87	0.2	0.95	Statistically insignificant. High heterogeneity. Ropivacaine group is comparable to bupivacaine
Onset of complete motor block	0.91	0.07-1.74	< 0.05	0.92	Significant difference. High heterogeneity. Bupivacaine is faster in onset than ropivacaine
Sensory blockade regression	-0.92	-1.81 to -0.03	< 0.05	0.93	Significant difference. High heterogeneity. Regression is faster with ropivacaine
Motor blockade recovery	-1.24	-2.15 to -0.32	< 0.05	0.94	Significant difference. High heterogeneity. Recovery is faster with ropivacaine
Duration of analgesia	-0.68	-1.18 to -0.19	< 0.05	0.79	Significant difference. High heterogeneity. Duration of analgesia is longer with bupivacaine
