OBJECTIVETo explore the effectiveness and prognosis on surgical treatment of posterior hip dislocations complicated with fractures of femoral head and acetabulum.

METHODSSeventeen patients with posterior hip dislocations complicated with fractures of femoral head and acetabulum were reviewed in the study. All the patients were treated with manual reduction within 12 hours after injury. CT location was used before operation. Absorbable screw fixation was performed for the femoral head fractures, while plate fixation or resection was performed for acetabular fractures.

RESULTSAll the patients got bony union within 6 months after operation without femoral head necrosis. Evaluate joint function according to Modifie Daobigne and Postal clinical classification criteria, 8 patients got an excellent result, 7 good and 2 fair. The excellent and good rate was 88.2%.

CONCLUSIONSurgical treatment can have a satisfactory prognosis for patient with posterior femoral head and acetabulum.

Objective:To establish the post competency evaluation index system for extracorporeal membrane oxygenation (ECMO) nurses.Methods:Based on semi-structured interviews, a preliminary post competency evaluation index system for ECMO nurses was developed. From May to June 2022, the Delphi method was used to conduct two rounds of consultation with 19 experts in critical illness field from 15 ClassⅢGrade A hospitals in 6 provinces and municipalities across the country to determine the evaluation index system. The analytic hierarchy process was used to determine the weights and consistency coefficients of indexes at all levels. The positivity of experts was expressed by the effective response rate of the questionnaire, the coordination degree of expert opinions was expressed by Kendall's W and coefficient of variation, the authority of experts was expressed by the authority coefficient of experts, and the concentration of expert opinion was expressed by the mean importance assignment and the perfect score rate. Results:In two rounds of expert consultations, the effective response rates of the questionnaires well all 100.00% (19/19), with expert authority coefficients of 0.834 and 0.879. The Kendall's W for the overall indicator in the second round of expert correspondence was 0.281 ( P<0.01), and the coefficient of variation of the indicators at all levels was 0.05 to 0.17. In the second round of consultation, the mean importance scores assigned to indicators at all levels was 4.05 to 4.95, with a perfect score of 21.05% to 94.74%. The final constructed post competency evaluation index system for ECMO nurses included 4 first-level indicators, 28 second-level indicators, and 59 third-level indicators. Conclusions:The post competency evaluation index system for ECMO nurses is scientific, reliable, and reasonable, which can provide reference for optimizing the ECMO nurse training system and improving evaluation standards.

The anastomotic vessels between the superior mesenteric artery and the inferior mesenteric artery are vital to maintain the blood supply of the anastomosis and residual colon after colectomy. However, current studies of anastomotic vessels are facing four major obstacles: confusing nomenclature, large variability in data, diversification of research methods and incomplete information records. The existence of marginal artery has been widely proved, and its significance for blood supply is well recognized by relevant studies. In contrast, the Riolan′s arch, whose connotations constantly changed over history, can not refer to a specific structure accurately. Researchers should abolish the controversial names such as Riolan′s arch, select appropriate research methods and record the anastomotic vessels in detail, so as to improve the comparability between different results. The study of anastomotic vessels can help us to identify potential vascular disease, select the appropriate surgical approach, and provide appropriate treatment of the vessels in the operating area, so as to provide a theoretical foundation and practical basis for fine surgical maneuvers.

Extracorporeal membrane oxygenation is an extracorporeal life support technique used to rescue patients with respiratory and (or) heart failure. Infection is one of the most serious complications of extracorporeal membrane oxygenation, which can affect patients' clinical outcomes. This article reviews the definition, diagnosis, incidence, site of infection, pathogenic bacteria, risk factors, prevention and treatment measures of extracorporeal membrane oxygenation associated nosocomial infection, so as to provide reference for the prevention and treatment of extracorporeal membrane oxygenation associated nosocomial infection.
