Events such as pregnancy and childbirth affect almost every fact of the human experience. Pregnancy alters a woman's body and mind. A partogram, also known as a partograph, is a single sheet of paper that has a composite graphical record of important labor-related data (fetal and maternal) entered against time. Statistics like cervical dilation, fetal heart rate, labor time, and vital signs are examples of pertinent metrics. The partograph is an invaluable tool for identifying indicators of maternal anxiety, irregular labor progress, and fetal distress. The partograph is intended to record the following: the mother's identity, the fetal heart rate, the color of the amniotic fluid, the fetal skull's molding, cervical dilatation, the fetal descent, the uterine contractions, and whether oxytocin was given or not. Objectives: Determine staff nurses in the experimental and control groups' degree of expertise & efficiency about using partograph during labor. Methodology: Research Design: True experimental research design used in study, Sampling technique & Population. . A basic random sample procedure was used to choose the 60 staff nurses for the study (30 in the experimental group and 30 in the control group). A study was conducted using a standardized interview schedule. . Result: In experimental group of staff nurses had 70% of adequate knowledge about partograph in post test and in control group 30 % of staff nurses only have adequate knowledge about partograph in post test . Conclusion The study helped the researcher to finalize the importance & use of partograph in labour among staff nurses in progress of labour. partograph is an invaluable tool for identifying indicators of maternal anxiety, irregular labor progress, and fetal distress.
