Study on the level of oral dryness and thirst of patients after cardiopulmonary bypass and its influencing factors

Objective To investigate the level and influencing factors of oral dryness and thirst in patients after cardiopulmonary bypass(CPB), so as to provide the basis for formulating measures to improve them. Methods A total of 112 patients underwent CPB in the Department of Cardiac Surgery of our hospital from July 2020 to December 2020 were investigated. Data collection included general information of patients, thirst score and disease data at 5 time points: 1 h, 6 h, 12 h, 18 h and 24 h after endotracheal intubation. Statistical analysis was carried out to obtain the levels of dry thirst and its influencing factors. Results The thirst level of patients reflected the overall slow downward trend from thirst score, subjective feeling and resting saliva flow rate. The changes of thirst score within 24 hours were affected by the patient’s blood chlorine level, blood volume per hour after extubation, blood loss per hour after extubation, dopamine pump speed after extubation, hematocrit, systolic blood pressure, and heart rate. Conclusion The change trend of patients’ thirst score was affected by changes of blood volume related indexes.
