Data processing and statistical analysis were performed using EPI/ PC.

Results: The results revealed that duration of third stage of labor in majority of selected women (49.6%) was 5-7 minutes. A considerable percentage of selected women had 21-30 years old. Higher percentage of women (41.9%) had primary education. Nearly 58.3% of selected women did not use analgesic and episiotomy performed in majority of selected women (67.5%). Majority of women (84.6%) of selected women had normal anthropometrics profile. Regression analysis showed no significant relation between third stage of labor with mother's parity (P> 0.05). But there are significant relation between episiotomy, usage analgesic and newborn weight with third stage of labor (P= 0.00).
