  • 30-day mortality risk and risk factors of patients with carbapenem resistant Acinetobacter baumannii in intensive care unit

    Objective To analyze the clinical characteristics, mortality risk and risk factors of patients with carbapenem resistant Acinetobacter baumannii (CRAB), so as to provide references for the prevention and control of CRAB. Methods Inpatients with Acinetobacter baumannii were selected from the clinical samples in the intensive care unit of Sichuan Academy of Medical Sciences and Sichuan Provincial People’s Hospital between January 2018 and December 2021. The patients were divided into CRAB infection group, carbapenem-sensitive Acinetobacter baumannii (CSAB) infection group and CRAB colonization group. Survival analysis was used to analyze the mortality risk and its influencing factors in patients with CRAB infection. Results A total of 696 patients were included. Among them, there were 392 cases of CRAB infection, 267 cases of CRAB colonization, and 37 cases of CSAB infection. The factors that increased the 30-day mortality risk of CRAB mainly included blood transfusion or use of blood products, mechanical ventilation, respiratory failure, maximum procalcitonin and age. Kaplan-Meier analysis showed that the 30-day mortality risk of CRAB infection group was higher than that of CSAB infection group(χ2=4.837, P=0.028), there was no significant difference between CRAB infection group and CRAB colonization group in 30-day mortality risk(χ2=0.219, P=0.640). Conclusions The mortality risk of CRAB infected patients is higher. Compared with the infection status, the 30-day mortality risk of patients is more attributed to drug resistance status. The effective method to control the mortality rate of CRAB should focus on reducing the hospital acquisition rate of CRAB.

  • Application of annular ligament reposition and repair via Henry’s approach for Monteggia fracture in children

    ObjectiveTo explore the effectiveness of annular ligament reposition and repair via Henry’s approach for Monteggia fracture in children.MethodsA clinical data of 21 children with Monteggia fractures was retrospectively analysed, who underwent open reduction of the radial head and annular ligament reposition and repair via Henry’s approach between May 2015 and July 2019. There were 11 boys and 10 girls with an average age of 8 years and 1 month (range, 4 years and 5 months to 14 years and 4 months). The fracture was caused by falling in 17 cases and by falling from height in 4 cases. There were 16 fresh fractures and 5 old fractures. The Monteggia fractures were rated as Bado typeⅠin 14 cases and Bado type Ⅲ in 7 cases. Preoperative MRI examination and intraoperative observation confirmed that the annular ligament was intact. After operation, the fracture healing, elbow range of motion (ROM), and complications were recorded, and the effectiveness was evaluated according to the Mackay’s function scoring system.ResultsThe incisions healed by first intention after operation, and there was no complication such as radial nerve injury. All children were followed up 12-25 months, with an average of 15 months. No dislocation or subluxation of the radial head occurred after operation. At last follow-up, the ROM of elbow flexion and extension of the children with old fractures increased from (92.6±11.2)° before operation to (123.6±11.6)°, and the ROM of forearm rotation from (96.8±11.8)° to (129.8±5.9)°; the differences between pre- and post-operation were significant (t=7.672, P=0.002; t=9.487, P=0.001); the ROM of elbow flexion and extension of the children with fresh fractures was 139°-156° (mean, 145°); the ROM of forearm rotation was 158°-168° (mean, 162°). According to Mackay’s criteria, 17 cases were excellent and 4 cases were good, with an excellent and good rate of 100%. X-ray film examination showed no nonunion, heterotopic ossification, or loosening of internal fixation after operation. The ulnar fracture and the ulnar osteotomy healed in all cases.ConclusionThe annular ligament in Monteggia fractures in children is intact. Compared with the reconstruction of the annular ligament, the reposition and repair of the annular ligament via Henry’s approach is closer to the original anatomical state of the annular ligament and has the advantages of less trauma and fewer complications.
