Abstract
Although there has been a reduction in the absolute number of maternal deaths caused by haemorrhage over the last 25 years , it remains the leading direct Obstetric cause of maternal deaths . Most deaths caused by haemorrhage occurr in the post partum period .
Cooling the uterus by placing an ice pack on the lower abdomen is one of the standard non pharmacological prophylactic strategies to prevent postpartum hemorrhage in Japan , the reasoning is that cold compress may help to contract the myometrium and decrease blood loss .Cold therapy causes blood vessels whithin the smooth muscles to constrict , which subsequently decrease blood flow . Furthermore , blood vessels in the skin are affected by cold , resulting in somatovisceral reflex and subsequent vasoconstriction of relevant internal organs .
So this study was aimed to use anew method( iced normal saline ) for direct cooling of the uterus to prevent bleeding and compared its efficacy with normal saline at room temperature .
In this study 220 subject were divided into two groups according to saline temperature which was used during CS to compare the efficacy of temperature on blood loss during CS .
Demographic data of the patients (age , parity , gravidity , gestational age , previous CS ) blood pressure ,AFI and INR don’t have any significant difference between cooling and non cooling group . Blood loss was compared between the two groups and there were , significant difference between the two groups as regard estimated total blood loss ،HB and HCT,as cooling decrease total blood loss and decrease incidence of atonic postpartum hemorrhage.As regard operation time , there was no statistically significant difference between the two groups.
