Objective To systematically evaluate the intervention effect of ice stimulation therapy on thirst of critically ill patients. Methods Databases including the PubMed,CINAHL, Embase, Cochrane Library, China National Knowledge Infrastructure, China Biology Medicine, Wanfang and VIP database were searched to collect the literatures on the intervention effect of ice stimulation therapy on thirst of critically ill patients with the time setting from the establishment to March 31, 2023. Two researchers screened the literature according to the literature inclusion and exclusion criteria, and extracted the data. Then RevMan 5.4 software was used for Meta-analysis. Results Ten studies involving 1 117 patients were included. Meta-analysis showed that ice stimulation therapy could alleviate thirst [MD=-2.867,95%CI(-4.102,-1.632),P<0.001] and dry mouth [SMD=-1.449,95%CI(-1.658,-1.240),P<0.001], improve the saliva pH value[MD=0.922,95%CI(0.824,1.021),P<0.001]. However, such intervention could not relieve the pain of thirst [SMD=-1.481,95%CI(-2.391,-0.571),P=0.050]. Conclusion Ice stimulation therapy can relieve the thirst and dry mouth of critically ill patients, and improve their saliva PH value. Such therapy is worthy further studying and applying.
