| Objective To analyze the constitute and clinical meaning of CTG,to investigate the correlation between CTG and Apgar,to analyze the changes of the incidence of fetal distress and the incidence of undergoing cesarean section with the use of CTG ,to direct the clinical use,to decrease the incidence of the perinatal mortality and morbidity,improves the quality of perinatal care.Methods 1536 cases with singleton pregnancy were analyzed,who were treated in the first hospital of Jilin University from January 1998 to December 2003,3278 CTG examination in third trimester pregnancy were performed.Every case have the NST test conventionally ,in total,there were 2440 NST test data,368 OCT test data and 470 CST test data.Results (1) In NST test,the group of 2086 cases reactive NST ,2025 cases (97.08%) neonatal Apgar scores ＞7, 61 cases (2.92%) neonatal Apgar scores ≤7；the group of 29 cases combined NST ,19 cases (65.52%) neonatal Apgar scores ＞7, 10 cases (34.48%) neonatal Apgar scores ≤7；the group of 325 cases non-reactive NST ,179 cases (55.08%) neonatal Apgar scores ＞7, 146 cases (44.92%) neonatal Apgar scores ≤7. Combined group compared with reactive one,the incidence of neonatal Apgar scores ≤7 increased significantly(P<0.01). Non-reactive group compared with reactive one,the incidence of neonatal Apgar scores ≤7 increased significantly(P<0.01).(2) In OCT test, the group of 321 cases negative OCT, 289 cases (90.03%) neonatal Apgar scores ＞7, 32 cases (9.97%) neonatal Apgar scores ≤7；the group of 17 cases suspicious OCT, 12 cases (70.59%) neonatal Apgar scores ＞7, 5 cases (29.41%) neonatal Apgar scores ≤7；the group of 30 cases positive OCT, 19 cases (63.33%) neonatal Apgar scores ＞7,11 cases (36.67%) neonatal Apgar scores ≤7.Suspicious group compared with negative one,the incidence of neonatal Apgar scores ≤7 increased significantly(P<0.05).Positive group compared with negative one,the incidence of neonatal Apgar scores ≤7 increased significantly(P<0.01).(3) In CST test,the group of 258 cases negative CST, 237 cases neonatal Apgar scores ＞7, 21 cases neonatal Apgar scores ≤7；the group of 187 cases suspicious CST, 152 cases neonatal Apgar scores ＞7,35 cases neonatal Apgar scores ≤7；the group of 25 cases positive CST, 17 cases neonatal Apgar scores ＞7,8 cases neonatal Apgar scores ≤7.Suspicious group and positive one compared with negative one respectively,the incidence of neonatal Apgar scores ≤7 increased significantly(P<0.01).(4) The constitute of abnormal FHR pattern,constituent ratio of VD pattern is 38.96%, constituent ratio of FHR-baseline without variability pattern is 2.60%, constituent ratio of bradycardia pattern is 20.78%, constituent ratio of tachycardia pattern is 16.88%, constituent ratio of LD pattern is 12.99%, constituent ratio of ED pattern is 7.79%.(5) The comparison of groups,the group of 2665 cases normal FHR pattern, 2551 cases neonatal Apgar scores ＞7, 114 cases neonatal Apgar scores ≤7；the group of 50 cases LD pattern, 8 cases neonatal Apgar scores ＞7, 42 cases neonatal Apgar scores ≤7；the group of 48 cases severe VD pattern,16 cases neonatal Apgar scores ＞7, 32 cases neonatal Apgar scores ≤7；the group of 10 FHR-baseline without variability pattern cases pattern, 3 cases neonatal Apgar scores ＞7, 7 cases neonatal Apgar scores ≤7. The group of LD pattern, the group of severe VD pattern and the group of FHR-baseline without variability pattern compared with the group of normal FHR pattern respectively,the incidence of neonatal Apgar scores ≤7 increased significantly(P<0.01).(6) The changes of the rate of fetal distress and the rate of cesarean section.The rate of fetal distress of our hospital in 1987 is 17.3%, the rate of fetal distress of our hospital in 1990 is 23.7%, the rate of fetal distress of our hospital in 1994 is 26.3%,the data of our test showing, the rate of fetal distress of our hospital in 1998 is 27.8%, the rate of fetal distress of our hospital in 1999 is 29.7%, the rate of fetal distress of our... |
