This study aims to comprehend the levels of dry mouth and thirst in patients after general anesthesia, and to identify the factors influencing them.
The study included all patients transferred to the Post Anesthesia Care Unit (PACU) at the Second Affiliated Hospital of Dalian Medical University between August 2021 and November 2021 after undergoing general anesthesia. A thirst numeric rating scale was utilized to conduct surveys, enabling the assessment of thirst incidence and intensity. Statistical analysis was performed to explore patient thirst levels and the associated factors.
The study revealed a thirst incidence rate of 50.8%. Among the thirst intensity ratings, 71.4% of patients experienced mild thirst, 23.0% reported moderate thirst, and 5.6% expressed severe thirst. Single-factor statistical analysis of potential risk factors among the enrolled cases indicated that gender, history of coronary heart disease, surgical duration, intraoperative fluid volume, intraoperative blood loss, intraoperative urine output, and different surgical departments were linked to post-anesthetic thirst in patients undergoing general anesthesia. Multifactorial Logistic regression analysis highlighted age, gender, history of coronary heart disease, fasting duration, and intraoperative fluid volume as independent risk factors for post-anesthetic thirst in patients undergoing general anesthesia. Moreover, age, gender, history of coronary heart disease, and intraoperative fluid volume were also identified as risk factors for varying degrees of thirst.
The incidence and intensity of post-anesthetic thirst after general anesthesia are relatively high. Their occurrence is closely associated with age, gender, history of coronary heart disease, fasting duration, and intraoperative fluid volume.
本研究旨在了解全麻后患者口干和口渴的程度，并确定影响这些症状的因素。
本研究纳入了 2021 年 8 月至 2021 年 11 月期间在大连医科大学第二附属医院麻醉后恢复室（PACU）转科的所有全麻患者。采用口渴数字评分量表进行调查，评估口渴的发生率和强度。采用统计学方法分析患者口渴程度及相关因素。
研究显示口渴发生率为 50.8%。口渴强度评分中，71.4%的患者表现为轻度口渴，23.0%的患者表现为中度口渴，5.6%的患者表现为重度口渴。对纳入病例的潜在危险因素进行单因素统计分析表明，性别、冠心病史、手术时间、术中液体量、术中出血量、术中尿量和不同手术科室与全麻患者术后口渴有关。多因素 Logistic 回归分析显示，年龄、性别、冠心病史、禁食时间和术中液体量是全麻患者术后口渴的独立危险因素。此外，年龄、性别、冠心病史和术中液体量也是不同程度口渴的危险因素。
全麻后口渴的发生率和强度相对较高。其发生与年龄、性别、冠心病史、禁食时间和术中液体量密切相关。
