545例新生儿窒息回顾性分析 总被引:4,自引:0,他引:4
目的 了解新生儿窒息的发生率,高危因素及其并发症发生情况,为防治新生儿窒息提供经验。方法 回顾性分析45337例活产新生儿中545例窒息新生儿的临床资料,分析新生儿窒息发生率及其影响因素。结果 从2001年至2006年,新生儿窒息发生率从2.13%(113/5298)降至0.35%(37/10466)(χ^2=97.560,P〈0.01)。男婴窒息发生率为1.43%(503/33723),明显高于女婴的0.95%(208/21834),差异有统计学意义(χ^2=22.070,P〈0.01)。产钳助产组的窒息发生率明显高于剖官产组及自然分娩组,差异有统计学意义(χ^2=114.835,P〈0.01)。早产儿窒息发生率为3.46%(70/2023),明显高于足月儿窒息发生率(1.09%,475/43314),差异有统计学意义(χ^2=90.911,P〈0.01)。自然分娩活婴中应用无痛分娩者窒息发生率为1.61%(111/6895),明显高于非无痛分娩儿的窒息发生率(1.09%,216/19749),差异有统计学意义(χ^2=11.231,P〈0.01)。在545例窒息新生儿中,引起窒息的前七位影响因素依次为胎儿窘迫、脐带异常、胎膜早破、母妊娠及内科合并症、早产、巨大儿及胎盘异常。新生儿并发症依次为肝功能受损、代谢及电解质紊乱、呼吸系统并发症、中枢神经系统损害、心肌损害、肾功能异常。结论重视新生儿窒息相关高危因素,选择合适的分娩方式,积极防治窒息后的器官功能损伤,加强新生儿窒息复苏培训及产儿合作,是降低新生儿窒息发生率和病死率的有效手段。 相似文献

Background The aim of this study was to establish the prognostic import of spontaneous fetal heart-rate deceleration, a sign of fetal distress.Methods This retrospective study enrolled 169 patients with fetal heart-rate deceleration treated at Shin-Kong Wu Ho Su Memorial Hospital from 1 January 1998 to 24 November 2000. Reviewed variables included type of fetal heart-rate irregularity (including early, variable, late, and spontaneous variants), neonatal outcome, Doppler results, gestational age and weight at birth, and amniotic fluid index.Results The spontaneous form of fetal heart-rate deceleration was determined for 11 of the 169 patients (6.5%) diagnosed with fetal heart-rate deceleration, with a 5-min Apgar score below 7 observed for 5 (45.5%) of these subjects, and neonatal complications for 9 (81.8%). Mean gestational age was 32.2±3.8 weeks; mean birth weight was 1,560±723.9 g. Spontaneous deceleration has a sensitivity of 29%, specificity of 99%, positive predictive value of 81.8%, and negative predictive value of 86.1%.Conclusion Although of the different fetal heart-rate deceleration types the spontaneous variant has the lowest incidence rate, the complication and mortality rates are highest and it is also associated with lower birth weight and higher incidence of pre-term labor. Failure of the fetus to cope with the compromised placental flow and uterine compression resulting from oligohydramnios may be fundamental to the etiology of spontaneous fetal-heart rate deceleration. Once diagnosed, Doppler ultrasound may be used to assess placental-vessel flow. Emergency treatment may be mandatory if deterioration is noted.Abbreviations AFI Amniotic fluid index - ITP Idiopathic thrombocytopenic purpura - GDM Gestational diabetes mellitus - SGA Small for gestational age restriction - PPV Positive predictive value - NPV Negative predictive value - S/D ratio Systolic/diastolic ratio - bpm Beats per minute - IUGR Intrauterine growth - IUFD Intrauterine fetal death - PPROM Pre-term premature rupture of membrane - RDS Respiratory distress syndrome 相似文献

A case of pleural effusion, diagnosed by ultrasound in the second trimester, underwent spontaneous resolution without adverse effect on lung development. Optimal management has not been defined; because the natural history of fetal pleural effusion is unknown, observation with serial ultrasound is an alternative to in utero therapy. 相似文献

In 35 two-hour recordings of fetal heart rate and fetal movements, 14 periods of fetal hiccups were present (1.2% of the recording time) with a median duration of 3.5 min (range 1 to 8 min). No specific relation to behavioural states or movement patterns could be identified. The hiccupping frequency varied from 10 to 21 per min. Within a hiccupping spell, the mean frequency decreased from 20 ± 11 to 12 ± 6.2 per min. A small but evident increase in baseline frequency was present during the hiccupping spells, independent from other movements performed by the fetus. 相似文献

A case is described in which amniocentesis caused placental injury, abruptic placenta, and fetal hemorrhage which caused fetal distress. This was primarily manifested by reduction of fetal movements and later by fetal heart rate deceleration. Emergency cesarean section was performed of monitoring the fetus after amniocentesis by assessment of fetal movements is stressed. 相似文献

Ultrasound remains the modality of choice in imaging the fetus due to its availability, safety, and low cost. With advances in technology, however, magnetic resonance imaging (MRI) has become an important adjuvant in the evaluation of the fetus. MRI is not limited by fetal lie, oligohydramnios, overlying bone, or obesity. MRI can image the fetus in any plane, providing a large field of view of the fetus and placenta with excellent soft tissue resolution of the brain, airway, lungs, and abdomen. Advanced techniques are being developed that provide volumetric data, spectroscopy, and functional images. MRI has its own set of challenges with a lack of consensus regarding its utility and safety. Artifact from the moving fetus and breathing mother limits the sequences available. While there is currently no evidence that fetal MRI produces harmful effects, long-term safety regarding radiofrequency fields and the loud acoustic environment continues to be studied. In this review, the benefits and potential risks of fetal MRI will be discussed. 相似文献

The purpose of this study was to determine the relationship between combined fetal biophysical activities, oligohydramnios, and fetal acid-base status at the time of testing. In a prospective study of 101 patients undergoing cesarean section before the onset of labor, a fetal biophysical profile was performed within 3 h before the cesarean section. Different combinations of fetal biophysical activities (fetal heart rate reactivity, fetal breathing movements, fetal body movements, and fetal tone) and oligohydramnios were correlated with umbilical cord blood gas and acid-base measurements (artery and vein). Fetal acidemia was defined as umbilical arterial blood pH <7.20. The group of fetuses with reactive nonstress test (NST) and/or fetal breathing present had significantly higher pH, pO2, bicarbonate, and base excess and significantly lower pCO2 levels compared with fetuses who had nonreactive NST, absent fetal breathing, and compromised or absent body movements and tone. These blood gas and acid-base differences were observed in both umbilical cord artery and vein. There was a significant relationship between oligohydramnios and fetal acidemia. Seven of 15 (46.6%) fetuses with oligohydramnios were acidemic and 7 of 15 (46.6%) acidemic fetuses had oligohydramnios (P = 0.0008). Fetuses with compromised or absent movements and tone had the highest incidence of acidemia (10 of 11 or 91%) and oligohydramnios (4 or 11 or 36%). The presence of oligohydramnios was associated with increased frequency of acidemia in every combination of biophysical activities. However, when all biophysical activities were absent, the frequency of acidemia was 100% regardless of the presence or absence of oligohydramnios. In conclusion, progressive loss of fetal biophysical activities is associated with increasing frequency and severity of fetal acidemia and oligohydramnios. 相似文献
