Friedman's partogram devised in 1954 was based on observations of cervical dilatation and foetal station against time elapsed in hours from onset of labour. The time onset of labour was based on the patient's subjective perception of her contractility. Plotting cervical dilatation against time yielded the typical sigmoid or 'S' shaped curve and station against time gave rise to the hyperbolic curve. Limits of normal were defined

Philpott and Castle in 1972 introduced the concept of "ALERT" and "ACTION" lines. The aim of this study was to fulfill the needs of paramedical personnel practising obstetrics in Rhodesian African primigravidae. The alert line represented the mean rate of progress of the slowest 10% of patients in the African population whom they served. Alert line was drawn at a slope of 1 centimetre/hr for nulliparous women starting at zero time i.e. time of admission . Action line drawn four hours to the right of the alert line showing that if the patient has crossed the alert line active management should be instituted within 4 hours, enabling the transfer of the patient to a specialised tertiary care centre. The action line was subsequently drawn two hours to the right of the alert line

Studd's labour stencils were introduced in 1972. These stencils predicted the expected pattern of progression of labour based on the extent of dilataton achieved by the time the patient is admitted (zero time). Curves showing the average course of cervical dilatation were constructed for various dilatation on admission. Five separate patterns representing normal labour progression were constructed. The curves were transcribed onto acrylic stencils On admission in labour, the cervical dilatation was assessed and a stencil was used to draw the relevant pencil line of expected progress on the patient's cervicograph which was then completed. Those crossing the nomogram line were found to have a three fold increase in instrumental delivery.

Hi friends! May I add something more about partogram?

It was first devised by E. A. Friedman in 1955. It is a graphical record of cervical dilatation in cm against duration of labour in hours. Zero time is time of admission. It is only applicable in vertex presentation.

It is a sigmoid curve. 1st stage of labour is devided as follows:

A. Latent phase
B. Active phase: 1. Acceleration phase- 2.5-4 cm
2. Phase of maximum slope- 4-9 cm
3. Phase of deceleration- 9-10 cm

Hugh Philpot added alert & action lines on the right of the phase of maximum slope. When graph crosses alert line- reassessment of woman's slow progress is done & when it crosses action line- decision for definite action is taken. Alert line is 2hrs right to normal slope & action line is 2 hours right to alert line.

So, I think she should be referred when the line is reaching action line.
