ABSTRACT
Objective:To summarize the treatment process of rapid decrease in blood flow due to centrifugal pump dysfunction during extracorporeal membrane oxygenation (ECMO) and its related thinking.Methods:On September 25, 2021, the ECMO treatment of a 14-year-old boy with severe mycoplasma pneumonia, severe viral pneumonia and acute respiratory distress syndrome (ARDS) admitted to the department of critical care medicine of the First Affiliated Hospital of Wannan Medical College was analyzed.Results:Oxygenation of the child was difficult to maintain under invasive mechanical ventilation, and lung consolidation progressed seriously. After evaluation, venous-venous ECMO (VV-ECMO) was implemented, then oxygenation was improved. In the 120th hour after VV-ECMO establishment, the blood flow sudden decreased, the speed was 3 822 r/min, while the flow was only 0.2 L/min, more over there was no change in the flow when the speed was increased. Before that, the ECMO speed was 3 530 r/min, and the flow was up to 3.4 L/min and stable. After rapid screening, it was determined that the centrifugal pump was dysfunction. ECMO was successfully replaced and the flow was satisfactory.Conclusions:At present, most ECMO centers do not routinely monitor the pressure before and after the pump. There is a lack of visual and quantitative techniques or indicators to judge the pump's function, and there is also a lack of corresponding clinical experience in treatment. This paper summarizes the investigation and treatment process of ECMO pump dysfunction of this case to provide reference.
ABSTRACT
Objective@#To discuss one double-eyelid surgery which is conformed to the anatomy characteristics of the asian upper eyelid.@*Methods@#A total of 162 cases were performed blepharoplasty for double eyelids, who aged 19 to 33 years with average 24.22±3.05 years, including 28 men and 134 women. Double eyelid line was designed according to the overall characteristics of eyebrows and eyes of beauty seekers combined with aesthetic standards. The surgery was performed to restore the anatomical characteristics of natural double eyelids as far as possible.@*Results@#The double eyelid surgery was designed and performed in 162 cases based on this method. All the patients underwent suture removal 7 days after operation, none of them had postoperative infection, and 15 patients had the bruising during the first week. After symptomatic treatment, the bruising had gone in 1 month. All the cases were followed up for more than six months postoperatively, and eight cases presented shallow double eyelid and the satisfactory results were achieved after the second operation of small incision.@*Conclusions@#The double-eyelid line should be designed individually before operation and the surgery done according to the natural characteristics of Asian upper eyelid. It will get coherent double eyelid without obvious scar or depression at resection margin, with high satisfactory rate.
