Brief summary
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.
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.
Interventions
PROCEDUREForced-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.

Exclusion criteria
* mothers younger than 18 years * mothers classified as American Society of Anaesthesiologists (ASA) status III or higher * caesarean section planned under general anaesthesia. * any expected problems with the newborn such as: * gestation date \< 36 or \> 42 week * placenta previa, abruption of placenta, green amniotic fluid, amnion infection syndrome or any abnormalities in cardiotocography (CTG)
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Body core temperature of the newborn | 20 min after birth | 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
| Measure | Time frame | Description |
|---|---|---|
| Skin temperature of the newborn | 20 min after child birth | 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
| Measure | Time frame | Description |
|---|---|---|
| Thermal comfort of the mothers | 20 min after child birth | Thermal comfort of the mother will be evaluated with a 100-mm visual analogue scale. |
| Mean arterial blood pressure of the mothers. | 20 min after child birth | Mean arterial blood pressure of the mothers will be assessed by non-invasive measurement. |
| Skin temperature of the mothers. | 20 min after child birth | Skin temperature of the mothers will be assessed at the chest. |
| Core temperature of the mothers | 20 min after child birth | Core temperature will be measured by a sublingual temperature probe. |
| Shivering incidence of the mothers | 20 min after child birth | Shivering of the mothers will be graded by a four-point scale. |
