290EXPLORING THE HYPOXIA INDEX AS A NUMERIC INDICATOR FOR FETAL HEART RATE DECELERATION IN THE PREVENTION OF CEREBRAL PALSY AND BRAIN DAMAGEThe goal is to prevent cerebral palsy and fetal brain damage. There was a study conducted to solve the vague late deceleration (LD) phenomenon by studying the hypoxia index. When a fetal brain is hypoxic, there is a loss of variability. In order to prevent cerebral palsy, the author sought a numerical indicator of the loss of variability in repeated FHR deceleration, but he could not find any. To calculate the hypoxia index (HI), the FHR deceleration durations were divided by the lowest FHR (bpm) and multiplied by 100 (perhaps using a computer). As of 2008, there were 25 and 26 cases with cerebral palsy and severe brain damage, whereas there were 20-24 cases with abnormal FHRs but no brain damage or cerebral palsy. Cerebral palsy must occur at 25 numeric thresholds, and 24 HI levels are considered safe. The baby will not develop CP if it is delivered before the HI reaches 25. In 3 connected LDs, HI was 6, whereas after 50 min's repetition, HI was 26, giving the indication that it does not depend on pattern, but on repetition. An HI is used to evaluate non-invasive fetal bradycardias, such as early, late, variable, and continuous forms, as well as digital fetal bradycardias, which are evaluated by a numeric HI. The HI incorporates all decelerations, while a computerized FHR diagnosis discards all decelerationsDr. Punam Kumari@gmail.comResearch1322023Cerebral Palsy,Hypoxia Index, Fetal BradycardiasDr. Punam KumariAssistant Professor, Department of Obstetrics and gynaecology, Lord Buddha Koshi Medical College and Hospital, Sahrasa, Bihar, India
