History of Changes
  Purpose

The purpose of this study was to see if a brief delay in cord clamping for 30 to 45 seconds would result in higher hematocrit levels, fewer transfusions, healthier lungs, and better motor function at 40 wks and 7 months of age.

Primary Outcome Measures:
  • VLBW infants in the delayed clamped group will have less chronic lung disease at 36 weeks postmenstrual age compared to VLBW infants in the immediate cord clamped grouped [ Time Frame: 36 wks postmenstrual age ] [ Designated as safety issue: No ]
  • VLBW infants in the delayed clamped group will have fewer incidences of suspected necrotizing enterocolitis during the NICU stay when compared with VLBW infants in the immediate cord clamped group [ Time Frame: Hospital discharge ] [ Designated as safety issue: No ]
  • VLBW infants in the delayed clamped group will have better motor function by 6 to corrected age when compared with VLBW infants in the immediate cord clamped group [ Time Frame: 7 months corrected age ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Infants in the delayed cord clamping group will have less IVH than infants in the immediate clamping group [ Time Frame: NICU stay ] [ Designated as safety issue: No ]
  • Infants in the delayed clamping group will hvae less late onset sepsis than infants in the immediate clamping group. [ Time Frame: NICU Stay ] [ Designated as safety issue: No ]

Arms Assigned Interventions
No Intervention: 1-ICC
infants received the routine care of immediate clamping of the umbilical cord
 Procedure: delayed cord clamping
cord clamping was delayed for 30 to 45 seconds and infant was held lower than the level of the placenta
Other Name: cord clamping time
Experimental: 2-DCC
after birth, cord clamping was delayed 30 to 45 seconds while infant was held lower than the level of the placenta.
