A meta-analysis of cognitive and functional outcomes in severe brain trauma cases.

Background: Severe traumatic brain injuries (TBIs) are an important health issue worldwide, which are associated with harmful side effects. This meta-analysis investigates the cognitive and functional outcomes in severe brain trauma cases. It assesses the impact on memory, verbal and visual abilities, attention, learning, and the presence of depression.

Clinical Effect of Modified Ultrasound-Guided Subclavian Vein Puncture.

Objective: This study compared the effect of ultrasound-guided subclavian vein puncture with traditional blind puncture and the double-screen control method by evaluating the one-time puncture success and total success rates, the completion time for puncture and catheterization, and short-term complications.

Methods: From January 2020 to January 2021, 72 patients with right subclavian venipuncture catheterization were collected, 12 of whom were excluded (including 3 cases of pneumothorax, 2 cases of hemothorax, 1 case of difficult positioning of thoracic deformity, 1 case of severe drug eruption, 3 cases of clavicle fracture, and 1 case of severe coagulation dysfunction). The remaining 60 cases were randomly divided into the traditional group ( = 30) and the improved group ( = 30).

Application of the ultrasound-guided double-screen contrast method in the standardized teaching and training of resident doctors in femoral vein puncture.

Objective: The aim of this study was to investigate the advantages of the double-screen contrast method compared with the short-axis ultrasound display method for teaching ultrasound-guided femoral vein puncture during the standardized training of resident doctors.

Methods: Sixty resident doctors undergoing standardized training were randomly divided into a test group (short-long axis switching double-screen contrast, = 30) and a control group ( = 30). These two groups of physicians underwent teaching and training of ultrasound-guided femoral vein puncture, and the success rate of the first puncture attempt, the total catheterization time, and any accidental femoral artery punctures were recorded and compared between the two groups.
