Relationship between Abdominal Circumference and Incidence of Hypotension during Cesarean Section under Spinal Anesthesia

Table 2

Hemodynamic outcomes according to the study group.

		Smaller AC group (n = 49)	Larger AC group (n = 51)	value
^aIncidence of hypotension		35 (71.40%)	40 (78.40%)	0.41
^bMaximal MAP decrease from baseline (mmHg)		28.33 (18.66–33.67)	36.67 (23.33–43.34)	<0.01
^bMaximal MAP percentage decrease from baseline (percent)		31.41 (22.74–39.22)	38.47 (28.00–44.81)	0.02
^aIncidence of bradycardia		9 (18.36%)	5 (9.80%)	0.21
^aIncidence of tachycardia		10 (20.40%)	10 (19.60%)	0.92
^bTotal ephedrine dosage (mg)		18 (6.75–30.00)	21 (15.00–30.00)	0.41

Data are presented as ^anumber (%) and ^bmedian (interquartile range). Data were analyzed using chi-square test and Mann–Whitney U test. All variables were evaluated 10 minutes after induction of spinal anesthesia. AC: abdominal circumference; MAP: mean arterial pressure.
