To determine the frequency of symptoms of hunger and thirst in a group of terminally ill patients and determine whether these symptoms could be palliated without forced feeding, forced hydration, or parenteral alimentation.
Prospective evaluation of consecutively admitted terminally ill patients treated in a comfort care unit.
Ten-bed comfort care unit in a 471-bed long-term care facility.
Mentally aware, competent patients with terminal illnesses monitored from time of admission to time of death while residing in the comfort care unit.
Symptoms of hunger, thirst, and dry mouth were recorded, and the amounts and types of food and fluids necessary to relieve these symptoms were documented. The subjective level of comfort was assessed longitudinally in all patients.
Of the 32 patients monitored during the 12 months of study, 20 patients (63%) never experienced any hunger, while 11 patients (34%) had symptoms only initially. Similarly, 20 patients (62%) experienced either no thirst or thirst only initially during their terminal illness. In all patients, symptoms of hunger, thirst, and dry mouth could be alleviated, usually with small amounts of food, fluids, and/or by the application of ice chips and lubrication to the lips. Comfort care included use of narcotics for relief of pain or shortness of breath in 94% of patients.
In this series, patients terminally ill with cancer generally did not experience hunger and those who did needed only small amounts of food for alleviation. Complaints of thirst and dry mouth were relieved with mouth care and sips of liquids far less than that needed to prevent dehydration. Food and fluid administration beyond the specific requests of patients may play a minimal role in providing comfort to terminally ill patients.
确定一组晚期患者饥饿和口渴症状的发生频率,并确定在不进行强制喂食、强制水化或胃肠外营养的情况下,这些症状是否能够得到缓解。
对在舒适护理病房连续收治的晚期患者进行前瞻性评估。
一家拥有471张床位的长期护理机构中的十张床位的舒适护理病房。
入住舒适护理病房期间,从入院到死亡接受监测的神志清醒、有行为能力的晚期患者。
记录饥饿、口渴和口干症状,记录缓解这些症状所需食物和液体的量及类型。对所有患者进行纵向舒适度主观评估。
在为期12个月的研究中监测的32例患者中,20例患者(63%)从未经历过任何饥饿,11例患者(34%)仅在最初有症状。同样,20例患者(62%)在晚期疾病期间要么没有口渴,要么仅在最初感到口渴。在所有患者中,饥饿、口渴和口干症状通常通过少量食物、液体和/或使用冰屑以及唇部润滑得以缓解。94%的患者的舒适护理包括使用麻醉剂缓解疼痛或呼吸急促。
在本系列研究中,晚期癌症患者一般不会感到饥饿,而有饥饿感的患者仅需少量食物即可缓解。通过口腔护理和少量饮水缓解口渴和口干的主诉,远远少于预防脱水所需的量。超出患者具体需求给予食物和液体,在为晚期患者提供舒适方面可能作用甚微。
