Draining Fluids through a Peritoneal Catheter in Newborns after Cardiac Surgery Helps to Control Fluid Balance

Table 1

Effect of the peritoneal drain on fluid balance after cardiac surgery. During the week preceding and following peritoneal drain removal we report the clinical severity data (PELOD score), diuretic therapy, parameters of the fluid balance, and renal function. Data were compared with the bilateral student 𝑇 test. P-value <  .05 was considered statistically significant.

	Peritoneal drain	No peritoneal drain	𝑃 value
PELOD score	8 ± 5	7 ± 5	.63
Furosemide (mg/kg/day)	4.5 ± 0	4.5 ± 1.5	.50
In/out Fluid balance (mL/day)	+53 (−309, +174)	+131 (−150, +339)	.06
Urine output (mL/kg/hr)	2.6 ± 0.7	3.1 ± 0.5	.19
Drain output (mL/kg/hr)	1 (0.3, 2.3)	0
FENa*	<10	<10
Serum creatinine (𝜇mol/L)	40 ± 6	45 ± 9	.22

*FENa: fractional excretion of sodium. (Results are expressed as median and range for fluid balance, drain and urine output and as mean and SD for Pelod score, furosemide therapy and renal function).
