Objective To investigate the incidence and influencing factors of hyponatremia in patients with traumatic cervical spi-nal cord injury(TCSCI).Methods The clinical data of TCSCI patients in our hospital from January2019 to December2021 were an-alyzed retrospectively.The patients'age,gender,cause of injury,severity(complete or incomplete SCI)and SCI level,serum sodi-um level,treatment strategy and days of injury hyponatremia were recorded.Whether the difference existed in the clinical data of pa-tients with hyponatremia was observed.Results There were 54 cases of hyponatremia in this study,and the incidence rate was 58.06%.Univariate analysis showed that there was no significant difference in gender,injury cause and albumin between hyponatremia and non hyponatremia patients(P＞0.05).There were significant differences in age,injury level,Asia grade,methylprednisolone shock,neurogenic shock,body temperature,coinfection and daily urine volume between the two groups(P＜0.05).Multivariate lo-gistic analysis showed that complete spinal cord injury and neurogenic shock were the risk factors for TCSCI patients(P＜0.05).Con-clusion The incidence of hyponatremia after TCSCI is 58.06%.Complete spinal cord injury and neurogenic shock are the risk factors for hyponatremia in patients with TCSCI.The level of sodium ion after TCSCI should be monitored early,as well as the early detection of hyponatremia and early intervention.
