Trauma is one of the leading causes of death and disability in children and adolescents. The children with multiple injuries have complicated and varied conditions. This article reviewed the traumatic scores of multiple trauma in pediatric patients. There are many kinds of trauma scores in children,each with advantages and disadvantages,but no trauma scores can meet all clinical and scientific requirements. The current injury severity score is the most widely used in-hospital scoring system. The child trauma score is the easiest pre-hospital scoring system. The BIG score is an emerging simple and easy scoring system. It is recommended that multiple assessments of multiple injuries in children should be repeated and combination of multiple scores are used.

Infection is the most common disease in children and a major problem that plagues clinicians.Imaging examination is an important tool for the diagnosis and evaluation of infectious diseases, providing evidences for early diagnosis.Although the imaging can not identify the pathogen, it can provide important clues for the determination of the pathogen, narrow the scope of the suspected pathogens, and provide a basis for the clinician′s empirical treatment.

Objective:To summarize the experience of the precise prevention and control strategy of novel coronavirus infection in the pediatric intensive care unit(PICU)during the epidemic of the Omicron variant.Methods:A retrospective analysis was performed on the strategies and management experience of precise prevention and control of novel coronavirus infection in PICU at Pediatric Hospital of Fudan University from March 1 to May 10, 2022.Results:According to the national and Shanghai novel coronavirus infection prevention and control standards, the PICU in our hospital, in accordance with the specialty characteristics of PICU, cooperated with the hospital′s department of infection and medical department to jointly construct a precise ward management strategy for the outbreak of the omicron mutants infection.Precise prevention and control management strategies were formulated from four aspects: the admission process of critically ill children, the division of PICU ward areas and nosocomial infection protection, the reception management system for children′s family members, and the " bubble management" system for PICU staff, and run them for 3 months.During the epidemic, there was no nosocomial infection of novel coronavirus infection in children or medical staff.During the period, a total of 140 critically ill children were admitted, including 87 cases transferred from the general ward in the hospital, 48 cases from the emergency department(non-febrile, 3 cases transferred by the transfer team), four cases from fever clinic, and one case from control ward.Four of the critically ill children had no emergency nucleic acid test report when they were admitted to the PICU.Among the 140 critically ill children, 54 patients received mechanical ventilation, 18 patients received blood purification, and two patients were monitored after liver transplantation.Seventy-eight (55.7%) children had underlying diseases.Conclusion:During the current round of novel coronavirus epidemic in Shanghai, PICU in our hospital formulated the admission and ward management procedures for critically ill children, which ensured the prevention and control of nosocomial infection of novel coronavirus, and at the same time ensured the treatment of critically ill children to the greatest extent.
