Abstract

                 During labor not only labor pain but also vaginal examinations cause adverse effects on a woman and her fetus. Thus, it is essential to develop a method to monitor labor progress besides vaginal examinations. This applied research aimed to develop the Prince of Songkla University Pain Curve instrument and test its sensitivity in predicting labor progress during the first stage of labor. Primiparous women were recruited by convenient sampling in a labor room at a central hospital in southern Thailand. In phase I (n = 350), pain (using the 100 mm Visual Analogue Scale) and duration of time from each cervical dilation were recorded and then the Pain Curve was developed. In phase II (n = 350), the instrument was examined for its sensitivity in prediction of labor progress.
                Results indicated that it had a slightly moderate sensitivity in predicting progress of labor from latent to maximum slope phases, but had a high sensitivity in the deceleration phase. The implication is that to monitor labor progress, it might be beneficial to use this instrument additional to standard curve instruments. Using the Prince of Songkla Pain Curve could also lower a number of vaginal examinations in assessment cervical dilations for predicting labor progress. Further testing and refinement of this instrument is required in the future with different samples including Thai women in larger sample size.
