Noradrenaline, Serotonin, GABA, and Glycine in Cerebrospinal Fluid during Labor Pain: A Cross-Sectional Prospective Study

Table 2

Concentrations of CSF neurotransmitters in pregnant women in the control and labor pain groups.

CSF neurotransmitters	Control group ()	Labor pain ()	value
Noradrenaline (ng/ml)	1.58 (1.03–1.91)	1.39 (1.13–1.62)	0.18
Serotonin (ng/ml)	5.44 (3.90–6.88)	3.76 (2.85–4.68)	<0.00
GABA (M)	0.04 (0.02–0.07)	0.03 (0.02–0.04)	0.08
Glycine (M)	19.13 (17.09–22.58)	25.22 (20.18–31.83)	<0.00

Data shown as median and interquartile range (P25–P75). value < 0.05 indicates statistical significance. GABA, gamma-aminobutyric acid.
