				        	Objective To analyse the clinical significance of variable deceleration and extended deceleration in non-stress test. Methods Studied the clinical characteristics of variable deceleration and extended deceleration of 200 cases who underwent non-stress test from January 2005 to December 2007, and compared corresponding clinical significance and newborn prognosis. Results Variable deceleration and extended deceleration in non-stress test dued to cord entanglement, polyhydramnios and fetal growth restriction. The occurrence of fetal distress and severe asphyxia in nowbom were less in low-grade variable deceleration (8.3%, 1.0%) than those in high-grade variable deceleration (17.7%, 4.8%)and extended deceleration (23.8%, 7.1%). Condusion Variable deceleration and extended deceleration in non-stress test due to cord entanglement mostly, low-grade variable deceleration is not always clue to fetal distress and high-grade variable deceleration and extended deceleration is often clue to fetal distress.
