Objective:To provide clinical data for early identification and diagnosis of vascular embolism in children.Methods:We collected and analyzed the clinical data of children with vascular embolism diagnosed at the Children Medical Center of the First Affiliated Hospital of Hunan Normal University from January 2017 to January 2020.Results:A total of 29 children with vascular embolism were included.The male to female ratio was 2.2∶1(20/9); the age range was 1 month to 13 years, and the median age(IQR) was 16 (6-41)months.Among them, 22 cases were diagnosed with venous thrombosis, including 13 children with lower limb venous thrombosis(13/29, 44.8%), and six children with intracranial venous thrombosis(6/29, 20.7%). Arterial embolism was found in six cases, and left atrial appendage thrombosis was found in one case.Severe pneumonia was the most common primary disease(19/29, 65.5%), followed by cardiopulmonary resuscitation(3/29, 10.3%), and Kawasaki disease(3/29, 10.3%). Analysis on the risk factors of vascular embolization diseases, including catheter-related, long-term bed rest, elevated D-dimer, mechanical ventilation, and intravenous hormone administration, showed that 89.2%(25/29)had ≥3 risk factors at the same time, and 82.8%(24/29)had ≥5 risk factors at the same time.Conclusion:In children with vascular thrombotic diseases, deep venous thrombosis, especially lower extremity venous thrombosis, are common.The severe pneumonia is more common in primary disease.Children with multiple risk factors have a higher risk of developing vascular embolism.In clinic, coagulation function should be monitored and local symptoms should be observed for early identification.

Objective To observe analgesia effect of morphine hydrochloride and hydromorphone hydrochloride in patients after transurethral resection of prostate. Methods Patients after transurethral resection of the prostate (TURP) were randomly divided into 2 groups, morphine hydrochloride group (n=45) and hydromorphone hydrochloride group (n=47). Analgesia, sedation efficacy and adverse reactions were evaluated at 6 and 24 h after they received epidural postoperative analgesia by using VAS score and Ramsay score. Results In 6 h, hydromorphone hydrochloride group had a better pain tolerance and feeling than morphine hydrochloride group (P<0.05) [(2.9±0.3) score vs.(1.3±0.2) score, (2.4±0.3) score vs. (0.9±0.2) score].However, in 6-12 h, the results were on the contrary (P<0.05) [(3.4±0.3) score vs.(5.4±0.3) score, (3.3±0.2) score vs. (5.7±0.4) score].After 24 h, there was no difference between the two groups (P>0.05).There were no differences in adverse reactions between the two groups ( P>0. 05 ) . Conclusion Hydromorphone has a better effect than morphine in epidural analgesia in 6 h.

Objective To analyze the clinical characteristics of fatal cases with confirmed severe ad﹣enovirus pneumonia in children in order to improve the diagnosis and treatment. Methods The fatal cases of severe adenovirus pneumonia admitted to Pediatric Intensive Care Unit of Hunan Provincial People′s Hospital from January 2019 to July 2019 were collected,whose clinical features,diagnosis,treatment,and the causes of death were analyzed retrospectively. Results A total of eight children were enrolled, and the age ranged from 3 months to 3 years old,and five cases were between 6 months to 2 years old. Three cases had underly﹣ing diseases. Adenovirus genotype identification was performed on six patients,and the results showed that all patients were infected with adenovirus type 7. All patients presented persistent high fever,with a peak temper﹣ature between 39. 8℃ to 41. 0℃,which persisted 10 to 37 days. Blood routine test before admission PICU showed that four cases had the decrease in white blood count and hemoglobin concentration,accompanied by﹣increased serum ferritin levels. Seven cases complicated with infection. Four cases had parainfluenza virus type 3 infection. Six cases had bacterial infection,and Gram﹣negative bacilli were predominant. One had fun﹣gal septicemia. Conventional mechanical ventilation were performed in all patients in this group. Four cases in this group died of severe acute respiratory distress syndrome. The other four cases died of disseminated intra﹣vascular coagulation associated with massive gastrointestinal bleeding, pulmonary hemorrhage, heart failure and septic shock combined with multiple organ failure. Conclusion Fatal adenoviruspneumonia mostly app﹣pears in children between 6 months to 2 years old or with underlying diseases. Adenovirus type 7 was the main serotype. The occurrence of reactive hemophagocytic phenomenon should be worsen progression of the disease. Co﹣infection may be an important cause of death.
