Most members of the general public find it difficult to identify poisonous wild mushrooms, resulting in family food poisoning. Toxic mushroom poisoning can produce nausea, vomiting, abdominal pain, and other severe symptoms 30 minutes or more after ingestion that can even lead to death. Using a "four-in-one" optimized emergency nursing procedure to treat mushroom poisoning can reduce the rescue time and improve the survival rate of patients. This study aimed to analyze the influence of a "four-in-one" optimized emergency nursing procedure to treat patients with toadstool poisoning. A prospective randomized study was conducted. Sixteen cases of toadstool poisoning, corresponding to 78 patients admitted to our hospital from January 2017 to July 2020, were selected and divided into a study group and a control group of 39 cases each using a random number table. The control group was provided with routine emergency care, and the study group was given a "four-in-one" treatment that optimized the emergency care process; both groups were subjected to basic treatment + blood purification and other treatment measures, and the treatment time in the rescue room and the first blood purification time of the two groups were compared. Differences in routine blood tests, liver and kidney function indices, hospitalization time, coma time, treatment outcome, and nursing satisfaction before and after treatment were found. The treatment time and the first blood purification time of the study group were lower than those of the control group, and the difference was statistically significant ( P < 0.05); ALT, AST, TBIL, TBA, and ALB were measured upon admission for the study and the control groups. The measured values of PT, APTT, CK, CK-MB, and BUN were compared for the two groups, but the difference in the values between the two groups was not statistically significant ( P > 0.05); after 7 days of treatment, the ALT, TBA, and APTT indicators of the study group were lower than those of the control group, and the difference was statistically significant ( P < 0.05); the measured values of ALT, AST, TBIL, TBA, ALB, PT, APTT, CK, CK-MB, BUN, and Scr after 7 days of treatment were significantly lower than those before treatment for both groups ( P < 0.05). The length of stay for the study group was lower than that for the control group, and the difference was statistically significant ( P < 0.05); the treatment efficiency was 87.18% for the study group, compared with 82.05% for the control group, but the difference was not statistically significant ( P > 0.05). The study group rated nursing care as follows: very satisfactory, 79.49%; relatively satisfactory, 15.38%; and acceptable, 5.13%; the control group rated nursing care as follows: very satisfactory, 51.28%; relatively satisfactory, 30.77%; and acceptable, 12.82%; the results were statistically significant ( P < 0.05). Using a "four-in-one" optimized emergency care process to treat patients with mushroom poisoning can significantly reduce the rescue room treatment time and the first blood purification time and improve nursing satisfaction, but has a limited effect on improving the treatment efficiency., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2022 Suling Li et al.)
