Objectives To explore the clinical diagnosis and treatment of Dieulafoy disease in children. Method The clinical features, endoscopic features and treatment of Dieulafoy disease in a child were reviewed. Results The 2-year-5-month old girl was admitted due to hematemesis for 7 hours. She was diagnosed of Dieulafoy disease by the typical endoscopic appearance. Gastroscopy showed that the lesion was located in gastric angle which was the predilection position of Dieulafoy disease. The small red blood vessels in the central part of the erosion area was exposed on the mucosal surface. The high frequency electrocoagulation under gastroscope was performed and effect was definite. Conclusion Dieulafoy disease is rare in children and lacks obvious clinical features. Endoscopic treatment has definite effect with little trauma and is the first choice of treatment.

Objective:To determine the potency of epidural ropivacaine in inhibiting breakthrough pain in primiparae undergoing labor analgesia with programmed intermittent epidural bolus (PIEB).Methods:American Society of Anesthesiologists Physical Status classification Ⅰ or Ⅱ primiparae of full-termpregnancy, with a singleton fetus in vertex presentation, aged ≥18 yr, with body mass index < 30 kg/m 2, presenting with breakthrough pain during labor analgesia with PIEB, were enrolled in this study. Ropivacaine 10 ml was epidurally administered, and the concentration was determined by up-and-down sequential allocation. The initial concentration was set at 0.15% in the first patient in each group. Each time the concentration increased/decreased in the next patient depending on whether the patients showed breakthrough pain relief, and the ratio between the two successive doses was 0.9. The criterion of breakthrough pain relief was defined as numerical rating scale score < 4 points within 30 min after epidural injection of ropivacaine. The median effective concentration (EC 50) and 95% confidence interval of ropivacaine in inhibiting breakthrough pain were calculated by Dixon-Massey′s method. Results:Twenty-six patients were finally included in this study.The EC 50 (95% confidence interval)of ropivacaine in inhibiting breakthrough pain was 0.102% (0.088%-0.117%). Conclusions:The EC 50(95% confidence interval) of epidurally administered ropivacaine 10 ml is 0.102%(0.088%-0.117%) when used for inhibiting breakthrough pain during labor analgesia with PIEB in primiparae.

【Objective】 To explore the effect of recovery autologous blood transfusion combined with bilateral internal iliac artery presetting in high-risk patients with hemorrhage during cesarean section. 【Methods】 A total of 162 high-risk patients with hemorrhage who underwent cesarean section from January 2021 to May 2023 in our hospital were prospectively selected and divided into in Groups A, B, and C with 54 cases in each group according to the indications for the method of transfusion. Group A received allogeneic blood transfusion, Group B received autologous blood transfusion, Group C received autologous blood transfusion combined with bilateral internal iliac artery balloon presetting. 【Results】 Intraoperative blood loss (mL) (1 600 vs 1 500 vs 800), postoperative hospital stay(d) (7 vs 7 vs 6) and operative time(min) (107 vs 104.50 vs 77) in group C were all lower than those in group A and B (P<0.05), with no difference between group A and B (P>0.05); The autologous blood transfusion volume(mL) in group C was lower than that in group B (525.5 vs 261, P<0.05). The proportion of allogeneic erythrocytes in group C was lower than that in group A (22.22% vs 100.00%, P<0.016 7). The proportion of plasma in group C was lower than that in groups A and B (18.50% vs 66.70%/18.50% vs 44.40%, P<0.016 7). The incidence of coagulating dysfunction in group C was lower than that in group A (7.41% vs 25.93%, P<0.016 7). The incidence of hysterectomy in group C was lower than that in group A (1.85% vs 16.67%, P<0.016 7), and there was no difference between group A and B (16.67% vs 11.11%, P>0.016 7). 【Conclusion】 Recovery autologous blood transfusion combined with bilateral internal iliac artery balloon presetting in cesarean section for high-risk patients with hemorrhage achieved ideal effects, which can significantly reduce intraoperative blood loss, intraoperative autologous blood transfusion, allogeneic red blood cells and plasma transfusion, as well as the operation time and postoperative hospital stay. In addition, it can improve the coagulation function and hysterectomy, which is conducive to ensuring the safety of maternal and promoting early rehabilitation, and preserving the fertility of patients to a certain extent, which is worthy of further clinical promotion.
