Bispectral Index Monitoring in the Nursing of Patients With Paroxysmal Sympathetic Hyperactivity

Abstract

Aim: To investigate the clinical nursing effect of bispectral index (BIS) monitoring for paroxysmal sympathetic hyperactivity (PSH) patients in the neurosurgical intensive care unit (NICU). Methods: From January 2022 to June 2023, a total of 30 patients with PSH secondary to moderate to severe craniocerebral injury in the NICU were monitored for BIS. The patients’ paroxysmal sympathetic hyperactivity-assessment measure (PSH-AM) scores were recorded. PSH patients generally appear in 3 states: calm state, seizure state, and postmedication state. Thirty PSH patients’ BIS values were recorded during the calm period, during the seizure state, and postmedication state, and these 3 different stages’ BIS values were divided into groups A, B, and C, using the Kruskal-Wallis H test to compare groups. Results: The Kruskal-Wallis H test yielded a value of H=22.599, P<0.001. H0 was rejected against the test standard of α=0.05, and the BIS values of groups A, B, and C differed. The BIS values of group A and group B differed after a pairwise comparison, and the difference was statistically significant (adjusted P=0.001). Group B and group C had different BIS values, and the difference was statistically significant (adjusted P=0.001); group A and Group C had no difference in BIS values, and the difference was not statistically significant (adjusted P=1.00). Conclusions: Taking BIS value as the nursing observation index for PSH patients can make nursing work more objective, reasonable, and accurate, reduce the inducing factors of PSH attack, further reduce the attack of PSH, save nursing resources, and help guide the safety assessment of sedative use.
