ABSTRACT
Objective:The purpose of this paper is based on the concept of enhanced recovery after surgery, to discuss the timing of taking food and water in knee arthroplasty patients, as well as its feasibility and safety, so as to improve the quality of quality nursing services.Methods:The 226 knee arthroplasty patients in Luoyang Orthopedic-Traumatological Hospital (Henan Provincial Orthopedic Hospital) from September 2020 to November 2021 were selected and divided into a control group and a experimental group using the random number table method, with 113 cases in each group. The control group adopted a conventional postoperative feeding management method; the experimental group adopted the early and timely feeding management method after comprehensive assessment. The data were compared between the two groups, including the incidence and severity of postoperative nausea and vomiting within 6 h and from 6 to 24 h after surgery , the incidence of thirst and hunger at 2 h, 4 h and 6 h postoperatively, and the comfort level.Results:The incidence of postoperative nausea and vomiting was lower in the experimental group [19.5%(22/113), 13.3%(15/113)] than in the control group [32.7%(37/113), 23.9%(27/113)] within 6 h and from 6 to 24 h after surgery, and the severity (21 cases of gradeⅠ, 10 cases of gradeⅡand 6 cases of grade Ⅲ) was also lower than in the control group (17 cases of gradeⅠ, 29 cases of gradeⅡand 18 cases of grade Ⅲ), and the differences were all statistically significant ( χ2 = 5.16,4.21, Z = -2.72, P<0.05). The incidence of thirst were lower in the experimental group [14.2%(16/113), 8.0%(9/113), 2.7%(3/113)] than in the control group [26.5%(30/113), 29.2%(33/113), 40.0%(35/113) at 2 h, 4 h and 6 h postoperatively, and the incidence of hunger at 4 h and 6 h postoperatively [11.5%(13/113), 8.0%(9/113)] were lower than in the control group [32.7%(37/113), 34.5%(39/113)], with statistically significant differences ( χ2 values were 5.35 to 32.39, all P<0.05). The postoperative comfort scale scores of physiological (31.04 ± 1.00) and psychological (33.50 ± 1.45) were higher in the experimental group than in the control group (27.46 ± 1.78) and (31.37 ± 1.29), and the differences were statistically significant ( t values were -102.36 to -66.26, all P<0.05). Conclusions:Early postoperative feeding management at the right time reduces the incidence and severity of postoperative nausea and vomiting inknee arthroplasty patients. In addition, it can also reduce the incidence of thirst and hunger, and improve patients′ postoperative physiological and psychological comfort, which has a facilitating effect on achieving rapid recovery of patients.
