Atypical Allergic Colitis in Preterm Infants

ABSTRACT. Two atypical cases of colitis due to cow's milk protein intolerance (CMPI) are reported, affecting preterm infants. One developed a toxic dilatation of the colon and responded well to a casein hydrolysate based feed. The second presented insidiously and failed to tolerate a casein hydrolysate, but responded well to a chicken-based modular feed.     

剖宫产术中大出血填塞纱条止血53例临床分析

目的观察宫腔填塞纱条对剖宫产术中大出血的止血效果。方法剖宫产术中大出血患者53例,常规处理方法无效后,采用宫腔填塞纱条止血,术中宫体注射缩宫素。以同期剖宫产50例为对照组,采用宫体注射缩宫素20U。结果53例经宫腔填塞纱条后,52例能迅速控制出血,有效率98.1%。与对照组比较,两组术后24h出血量、术后5d、42d子宫径线和无显著差异(P>0.05)。结论宫腔填塞纱条治疗剖宫产术中大出血有积极作用。     

Persistent right umbilical vein: incidence and significance.

OBJECTIVES: To conduct a prospective evaluation of the incidence and neonatal outcome of fetuses with persistent right umbilical vein. This condition had traditionally been considered to be extremely rare and to be associated with a very poor neonatal prognosis, but later evidence has raised some doubts about the veracity of these contentions. METHODS: Between August 1995 and November 1998, 8950 low-risk patients were prospectively evaluated at two medical centers. The sonographic diagnosis of a persistent right umbilical vein was made in a transverse section of the fetal abdomen when the portal vein was curved toward the stomach, and the fetal gall bladder was located medially to the umbilical vein. RESULTS: Persistent right umbilical vein was detected in 17 fetuses during the study. Four of them had additional malformations, of which three had been detected antenatally. CONCLUSIONS: We established that the incidence of persistent right umbilical vein in a low-risk population is 1 : 526. We believe that the sonographic finding of this anomaly is an indication for conducting targeted fetal sonography and echocardiography. When the persistent right umbilical vein is connected to the portal system and other anomalies are ruled out, the prognosis can generally be expected to be favorable.     

宫腔镜手术的麻醉处理

目的探讨宫腔镜手术麻醉方式的选择及其对患者呼吸循环的影响以及对水中毒预防的体会。方法选取416例妇科宫腔镜手术患者,根据手术种类及难易程度分别采用静脉全麻,腰-硬联合阻滞麻醉及静-吸复合全麻。术中连续监测各项生命体征,观察麻醉前后对患者呼吸循环的影响。同时为防止水中毒的发生,凡是手术时间超过1h,膨宫液超过10000ml以上的宫腔镜手术,预防性地应用呋塞米20~40mg。结果静脉麻醉诱导后,全组病人的RR(呼吸频率),HR(心率),MAP(平均动脉压)均有不同程度降低,与诱导前比较有显著性差异(P<0.01)但仍在正常范围内,无需处理,术毕即恢复正常。在正常吸氧情况下SpO2(血氧饱和度)差异无显著性(P>0.05)。联合阻滞麻醉前后各时点的HR,MAP,RR,SpO2均无明显变化。结论虽然宫腔镜手术是微创手术,但潜在的危险性依然存在,对于麻醉来说,除了选择合适的麻醉方式,为手术提供良好的镇静和肌松条件外,还要进行一系列麻醉监测,密切观察患者的各项生命体征,适当地使用呋塞米可有效预防水中毒。
