Abstract:
Objective:To investigate the current status of maximum tongue pressure (MTP) in cardiac surgery inpatients and analyze its influencing factors, providing a basis for developing personalized nursing measures for high-risk groups.Methods:This cross-sectional study used a convenience sampling method to select cardiac surgery inpatients at Zhongshan Hospital, Fudan University, from January 2022 to April 2023. General and clinical data questionnaires, a swallowing tongue muscle evaluation training device, and a hand dynamometer were used for data collection. The random forest model and Lasso regression were employed to identify key influencing factors, and multiple linear regression was used to analyze the factors affecting MTP.Results:A total of 501 cardiac surgery inpatients meeting the inclusion and exclusion criteria were enrolled, including 308 males and 193 females, with a mean age of (56.94 ± 14.02) years. The mean MTP was (45.92 ± 9.57) kPa. When the lambda (λ) value was 0.181, the model achieved the best fit, identifying 10 key influencing factors in descending order of importance: age, handgrip strength, gender, BMI, N-terminal pro-B-type natriuretic peptide (NT-proBNP), glomerular filtration rate, cardiac function grade, hemoglobin, history of stroke, and history of atrial fibrillation. Age, handgrip strength, low-level BMI, NT-proBNP, and history of stroke were determined as significant factors influencing MTP in cardiac surgery inpatients ( R2 = 0.324, F = 24.92, P<0.05). Conclusions:Nurses should pay close attention to the tongue muscle strength of cardiac surgery inpatients. Early assessment of MTP is essential for older patients, those with low handgrip strength, low BMI, elevated NT-proBNP, or a history of stroke. Targeted early identification and pre-rehabilitation measures should be implemented for patients with weakened tongue muscle strength.
