心脏体外循环术后患者口干口渴水平及影响因素研究

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

目的了解心脏体外循环术后患者口干口渴水平及影响因素,为制定改善患者口干口渴程度的措施提供依据。方法选取2020年7月至2020年12月在本院心外科行体外循环手术的112例患者进行调查研究,数据采集内容包括患者一般资料,拔除气管插管后1 h、6 h、12 h、18 h、24 h共5个时间点的口渴评分及疾病学资料,进行统计学分析,得出患者口干口渴水平及其影响因素。结果患者的口渴水平从口渴评分、主观感受、静息唾液流率三个方面反映出整体缓慢下降的趋势,患者血氯值、拔管后每小时入血量、拔管后每小时出血量、拔管后多巴胺泵速、红细胞压积、收缩压、心率对患者24 h内口渴评分的变化有影响。结论患者口渴评分的变化趋势受血容量相关指标变化的影响。

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.
