  Purpose

This study should evaluate whether newborns during cesarean section are endangered to get hypothermic while bonding on the mothers chest.

Therefore, the investigators want to investigate the effects of active cutaneous warming of the mothers and babies during intraoperative bonding. The investigators plan to enroll 40 parturients scheduled for elective caesarean section to receive passive insulation or forced-air skin surface warming. The investigators will measure core temperature of the newborns and their mothers. The investigators hypothesize that newborns became most often hypothermic without active warming during the bonding procedure and that active warming will be able to decrease the number of hypothermic newborns significantly.

Primary Outcome Measures:
  • Body core temperature of the newborn [ Time Frame: 20 min after birth ] [ Designated as safety issue: Yes ]
    Core temperature of the infants will be measured with specific probes 20 min after birth (end of bonding period)by a rectal temperature probe.


Secondary Outcome Measures:
  • Skin temperature of the newborn [ Time Frame: 20 min after child birth ] [ Designated as safety issue: Yes ]
    Skin temperature of the infants will be measured with specific probes 20 min after birth (end of bonding period) at chest, arm, thigh, and calf. Mean-skin temperature will be calculated from these measurements.


Other Outcome Measures:
  • Shivering incidence of the mothers [ Time Frame: 20 min after child birth ] [ Designated as safety issue: No ]
    Shivering of the mothers will be graded by a four-point scale.

  • Thermal comfort of the mothers [ Time Frame: 20 min after child birth ] [ Designated as safety issue: No ]
    Thermal comfort of the mother will be evaluated with a 100-mm visual analogue scale.

  • Mean arterial blood pressure of the mothers. [ Time Frame: 20 min after child birth ] [ Designated as safety issue: Yes ]
    Mean arterial blood pressure of the mothers will be assessed by non-invasive measurement.

  • Core temperature of the mothers [ Time Frame: 20 min after child birth ] [ Designated as safety issue: No ]
    Core temperature will be measured by a sublingual temperature probe.

  • Skin temperature of the mothers. [ Time Frame: 20 min after child birth ] [ Designated as safety issue: No ]
    Skin temperature of the mothers will be assessed at the chest.

Arms Assigned Interventions
No Intervention: Control; passive insulation
The mothers will receive passive temperature insulation by a cotton blanket (standard procedure) after start of the spinal anaesthesia for cesarean section. The newborn will be bonded on the mothers chest under the cotton blanket (also passive insulation without active warming) for 20 min after birth (bonding period).
Experimental: Active Warming
The mothers will receive active warming by a forced-air warming blanket after start of the spinal anaesthesia for cesarean section. The newborn will be bonded on the mothers chest under the warming blanket for 20 min after birth (bonding period).
Procedure: Forced-air warming
In the intervention group a forced-air cover (Level 1 Snuggle Warm Upper Body Blanket, Smiths Medicals) will be positioned over the upper body of the patients laying on the operating table just beginning after the spinal block.
Other Names:
  • Level 1 Snuggle Warm Upper Body Blanket
  • Forced-air warming blower

Detailed Description:

Little is known about the thermoregulatory effects on babies when bonding on the chest of the mother during caesarian section. The aim of our study is to evaluate whether newborns during cesarean section are endangered to get hypothermic while bonding on the mothers chest. The investigators want to investigate the effects of active cutaneous warming of the mothers and babies during a 20 min intraoperative bonding period. The investigators plan to enroll 40 parturients scheduled for elective caesarean section under spinal anaesthesia to receive passive insulation or forced-air skin surface warming. The investigators will measure core temperature of the newborns and their mothers. The investigators hypothesize that newborns became most often hypothermic without active warming during the bonding procedure and that active warming will be able to decrease the number of hypothermic newborns significantly.
