Aim Of The Study:
To evaluate the influence of warmed infusions on the mothers and newborns well-being after C-section.
Design:
Prospective randomized study.
Setting:
Dept. of Anaesthesiology, Resuscitation and Intensive Care Medicine, Dept. of Obstetrics and Gynaecology, Faculty of Medicine and Dentistry Palacký University and University Hospital Olomouc.
Methods:
Prospective randomized study including 29 pregnant women between 38th and 42nd week of pregnancy, that were indicated to elective caesarian section (SC) and from all of which the fetal distress was excluded. The women were randomized into four groups according to the temperature of applied infusion solution - colloids and afterwards crystalloids (pre-heated and non pre-heated), and according to the type of anaesthesia (general or SAB). These values were monitored in perioperative period: body temperature, differences of hemoglobin and hematocrit levels, tremor and pain level after the operation. In newborns the acid-base balance parameters and Apgar score were monitored.
Results:
The study is still going on, however up to now some of the results suggest that usage of pre-heated infusion solutions is effective both for mother and child in increasing of their comfort in the perioperative period. In the group of actively heated mothers we have noticed: lower perioperative blood loss - differences in haemoglobin levels were 8 g/l compared to 15 g/l in the group of non heated mothers. The umbilical cord blood of the newborns whose mothers were not actively heated and were operated in subarachnoid anaesthesia had the lowest pO2 (0.9 kPa). The lowest level of umbilical cord blood lactate was noticed in the group of newborns whose mothers underwent the surgery under general anaesthesia and were actively heated.
Conclusion:
Up to now results suggest that the heating of mothers during the SC lowers the loss of body temperature, blood loss, and perception of pain by the mother. In combination with general anaesthesia it increases pO2 and lowers the levels of lactate in umbilical arteria in the newborns.
