Table 3 Maternal outcomes in three groups

From: Effects of continuous infusion of phenylephrine vs. norepinephrine on parturients and fetuses under LiDCOrapid monitoring: a randomized, double-blind, placebo-controlled study

Variables Control group (n = 78) Phenylephrine group (n = 71) Norepinephrine group (n = 74) χ2 value df P value
Bradycardia (n) 0 (0) 0.03 (2) 0.01 (1) 2.22 2 0.329
Tachycardia (n) 0.10 (8) 0 (0) * 0 (0) # 15.43 2 < 0.001

  1. Data expressed as rate (number);*0.25 μg/kg/min phenylephrine vs. control group, P < 0.05; #0.05 μg/kg/min norepinephrine vs. control group, P < 0.05; †0.25 μg/kg/min phenylephrine vs. 0.05 μg/kg/min norepinephrine group, P < 0.05 based on chi-squared test. (after Bonnfini adjust the P value < 0.0167 has the significant different for inter-group comparison)
