Abstract:
Prospective randomized trial. Setting: Ward 17 Colombo South Teaching Hospital
population: patients who were undergoing caesarian section at term (37weeks to 42week)
from 28/12/2005 to 30/4/2006. All the patients who fulfill selection criteria were randomly
allocated to two groups. Five units of oxytocin were given intravenously once baby was
delivered completely. If the patient is selected to test group 5 iu of additional oxytocin dose
was given to umbilical vessel close to its insertion once umbilical cord was clamped. If
patient was selected to control group only 5iu of oxytocin was given intravenously once
baby was completely delivered. Placental separation time was calculated and mean
placental separation times were statistically compared. All together 87 patients are
randomized to two groups. Forty. three subjects include in test group. Forty four subjects
randomized into control group. Mean age of the test group is 28.09 years. Mean age of the
control group was 31.27.Mean gravidity were 1.9 and 2.3 in test and control groups
respectively. Mean parity was 0.88 and 1.32 in test and control groups respectively. Mean
number of children were 0.72 and 0.98 in test and control groups respectively. Mean
placental sepal'ation time of test group (Intravenous + Intra-umbilical vein) was 96.51s (SD
