Analysis of risk factors and language rehabilitation nursing strategies for CMS after pediatric medulloblastoma surgery

Abstract Objective To investigate the occurrence of CMS in children with medulloblastoma after surgery and analyze its risk factors. Methods The clinical data of 217 children with medulloblastoma who underwent tumor resection in pediatric neurosurgery of comprehensive first- class hospital in Beijing from April 2019 to March 2022 were retrospectively analyzed. According to the consensus of Iceland Delphi, CMS was diagnosed. According to whether CMS occurred after surgery, they were divided into CMS group and non CMS group, Logistic regression analysis was used to identify the risk factors for CMS in children with medulloblastoma after surgery. Results Out of 217 children with medulloblastoma, 36 developed CMS after surgery, with an incidence rate of 16.6%. The results of logistic regression analysis showed that tumor infiltration into the pons, supratentorial hydrocephalus, and intraoperative blood transfusion were risk factors for postoperative CMS in children with medulloblastoma. Conclusion The incidence of CMS in children with medulloblastoma after surgery is relatively high. Tumor infiltration into the pons, supratentorial hydrocephalus, and intraoperative blood transfusion can diagnose the occurrence of CMS in children with medulloblastoma after surgery. Nursing staff should pay attention to the mutism symptoms of children with medulloblastoma after surgery, and implement early language rehabilitation nursing interventions.
