Abstract:

Objective　To investigate the thirst current situation and influencing factors after cardiopulmonary bypass. Methods　This study was a retrospective analysis. Clinical data of 65 patients with cardiopulmonary bypass admitted to Fuwai Central China Cardiovascular Hospital from March 2021 to April 2023 were collected, including 32 males and 33 females, aged (53.25±2.35) years, with a body mass index of (22.65±1.05) kg/m². The Thirst Distress Scale (TDS) was used to evaluate postoperative thirst in patients with cardiopulmonary bypass (CPB) after the removal of tracheal intubation (usually 2 ~ 3 days after surgery). The patients' gender (male/female), age (≥60 years old /<60 years old), education level (high school and below/college and above), underlying diseases (yes/no), duration of cardiopulmonary bypass (≤30 min/>30 min) disease type (coronary artery bypass surgery/tetralogy of Fallot/others), diuretic type (<2 types/≥2 types), serum sodium ion, mechanical ventilation time (≤3 h/>3 h), disease perception (good/poor), Self-Rating Anxiety Scale (SAS) score (≥50 points /<50 points), Self-Rating Depression Scale (SDS) score (≥53 points/<53 points), and attitude and behavior towards sodium restricted diet (good/poor) were collected and compared. Logistic regression analysis was used to examine the influencing factors of postoperative thirst in patients with cardiopulmonary bypass. t test was used for statistical analysis. Results　The TDS score of the 65 patients with cardiopulmonary bypass was (34.62±1.35) points. The TDS scores of the patients with age <60 years old, SAS score ≥50 points, SDS score ≥53 points, poor disease perception, and poor attitude and behavior towards sodium restricted diet were higher than those of the patients with age ≥60 years old, SAS score <50 points, SDS score <53 points, good disease perception, and good attitude and behavior towards sodium restricted diet [(35.71±1.25) points vs. (16.22±1.05) points, (34.88±1.75) points vs. (22.73±1.50) points, (35.56±1.67) points vs.(30.50±1.22) points, (37.50±1.85) points vs. (28.80±1.50) points, (37.67±1.88) points vs. (28.18±1.53) points], with statistically significant differences (t=68.253, 31.885, 14.653, 19.782, and 20.442, all P<0.001). Multiple linear regression analysis showed that age, SAS score, SDS score, disease perception, and attitude and behavior towards sodium restricted diet were all influencing factors of postoperative thirst in patients with cardiopulmonary bypass (all P<0.05). Conclusion　The patients with cardiopulmonary bypass have a higher TDS score after operation. Patients' age, SAS and SDS scores, disease perception, and attitude and behavior towards sodium restricted diet are all important factors affecting the TDS score in patients with cardiopulmonary bypass.
