Abstract：Objective To investigate the current situation and influencing factors of hypersomnia in convalescent patients during the recovery period after cerebral infarction.Methods A total of 98 patients in the rehabilitation period after cerebral infarction admitted to the Third People's Hospital of Nanyang from May 2022 to April 2024 were selected as the study objects.Data of these patients were collected,and Epworth Sleepiness Scale(ESS),Self-rating Depression Scale(SDS),Self-rating Anxiety Scale(SAS),National Institutes of Health Stroke Scale(NIHSS)and Pittsburgh Sleep Quality Index(PSQI)were used to evaluate sleepiness,depression,anxiety,neurological impairment and sleep quality of patients in the rehabilitation period after cerebral infarction.Pearson correlation analysis was used to investigate the correlation between excessive sleepiness and negative mood,neurological impairment and sleep quality in patients recovering from cerebral infarction.t test and one-way analysis of variance were used to compare the differences of hypersomnolence in patients with different characteristics after cerebral infarction.Multiple linear regression was used to analyze the influencing factors of excessive sleepiness in patients convalescing after cerebral infarction.Results The incidence of excessive sleepiness was 42.86%(42/98)in 98 patients after cerebral infarction,with ESS score(8.47±1.55),SDS score(58.39±6.37),SAS score(53.44±6.12),National Institutes of Health Stroke Scale(NIHSS)score(13.61±2.05),Pittsburgh Sleep Quality Index Scale(PSQI)score(5.06±1.12).Pearson correlation analysis showed that ESS scores were positively correlated with SDS,SAS,NIHSS and PSQI scores in patients recovering from cerebral infarction(P<0.05).ESS scores of females,age≥60 years old,family per capita income≥4 000 RMB,site of cerebral infarction(thalamus),number of complications≥2 kinds of patients after cerebral infarction were higher than those of males,age<60 years old,family per capita income<4 000 RMB,site of cerebral infarction(cerebral cortex/brain stem/other),number of complications<2 kinds of patients(P<0.05).Multiple linear regression analysis showed that age≥60 years old,location of cerebral infarction(thalamus),number of complications≥2,high SDS score,high SAS score,high NIHSS score and high PSQI score were independent risk factors for excessive sleepiness in patients recovering from cerebral infarction(P<0.05).Conclusions The incidence of excessive sleepiness is higher in patients recovering from cerebral infarction,and it is related to age,location of cerebral infarction,number of complications,negative emotion,degree of neurological impairment and sleep quality.Medical staff should pay more attention to excessive sleepiness in patients recovering from cerebral infarction,evaluate the sleepiness regularly,and implement preventive intervention as soon as possible for high-risk groups,so as to reduce the occurrence of excessive sleepiness.
