Meta Analysis Comparative Study
ST waveform analysis versus cardiotocography alone for intrapartum fetal monitoring: a meta-analysis of randomized trials.
To estimate the effectiveness of intrapartum ST waveform analysis (STAN) versus cardiotocography (CTG) alone in prevention of metabolic acidosis. ⋯ There is no difference in perinatal outcomes between STAN with CTG compared with CTG alone, except for lower rate of OVD.
