Gender-related plasma levels of progesterone, interleukin-8 and interleukin-10 during and after cardiopulmonary bypass in infants and children

Table 2 Physical characteristics of the patients, and operative and outcome measures

Parameter	Male (n = 10)	Female (n = 8)	P
Age (months)	17 (2–185)	27 (8–55)	0.21
Body weight (kg)	9.6 (4.0–68)	10.4 (5.7–16)	0.72
Body length (cm)	80 (54–169)	81 (65–102)	0.76
Body surface area (m²)	0.45 (0.23–1.78)	0.46 (0.30–0.68)	0.72
Cardiopulmonary bypass time (min)	103 (79–218)^*	89 (27–131)	0.08
Cross-clamping (min)	71 (31–129)^*	46 (13–93)	0.10
Mechanical ventilation (h)	17 (2–111)	4.8 (2–18)	0.20
Intensive care unit (days)	2 (1–20)	2 (1–5)	0.51
Multiple organ dysfunction (n)	6	0	0.01

Median (minimum, maximum) age, body weight and length, body surface area at operation and duration of cardiopulmonary bypass, aortic cross-clamping time, duration of mechanical ventilation, and days on the intensive care unit for male and female patients (Mann–Whitney U-test). The incidence of multiple organ dysfunction is also shown (Fisher's exact test). ^*Times for the patient who underwent a second cardiopulmonary bypass run because of a residual shunt are cumulative.
