Abstract

          This quasi-experimental research aimed to examine the time of lower uterine segment compression immediately after placental delivery to the amount of blood loss within a 1 hour postpartum period. The sample was collected from low risk mothers who had normal deliveries in Chiangrai. The sample of 90 cases was recruited by simple random sampling and these were divided into three groups, one group of the experimental group, one group of the comparison group and one group of the control group, with 30 cases per group. In the experimental group, the participants were assisted by lower uterine segment compression immediately after placental delivery for 20 minutes. In the comparison group, the participants were assisted by lower uterine segment compression immediately after placental delivery for 10 minutes. In the control group, the participants received standardized nursing care. Research experimental instruments included the handbook for the lower uterine segment compression, the measuring blood bag, the digital weighing scales and the blood loss record form with its inter-rater reliability of .90.  Data were analyzed by using descriptive statistics and one way analysis of variance.

          The results revealed that the experimental group had a significantly lower mean of blood loss within a 1-hour postpartum period than the control group (p<.05). The comparison group had a significantly lower mean of blood loss within the 1-hour postpartum period than the control group (p<.01) and the comparison group and the experimental group had  a mean of blood loss that did not differ with statistical significance.

          These findings suggested that the lower uterine segment compression immediately after placental delivery for 10 minutes could reduce the amount of blood loss within the 1-hour postpartum period.
