Abstrakt:	Objective: To study the difference of the clinical manifestations between single and mixed acute organophosphate (OP) poisoning. Methods: The clinical signs and symptoms, the activity of cholinesterase (ChE) in erythrocytes, plasma and whole blood, and the level of AST, CK, LDH and ALT were compared between a single OP poisoning group (Group S) and a mixed OP poisoning group (Group C). Results: Group S and Group C compare with: (1) Symptoms and signs on arrival at hospital: Group C was found to have more cases showing, nausea and vomiting than group S with obvious difference (P < 0.05). (2) The rates of other symptoms and signs were of no significant difference between the 2 groups. The activity of cholinesterase of the 2 groups on arrival at hospital: Whole blood ChE < 0.30: 16 cases and 14 cases; > 0.30 approximately : 24 cases and 19 cases; 0.50 approximately 0.70: 14 cases and 17 cases; erythrocyte ChE < 0.30: 18 cases and 14 cases; > 0.30 approximately : 22 cases and 21 cases; 0.50 approximately 0.70: 14 cases and 15 cases; plasma ChE < 0.30: 28 cases and 25 cases; > 0.30 approximately : 10 cases and 12 cases; 0.50 approximately 0.70: 16 cases and 13 cases; chi(2) = 0.852, 1.444, 0.509. There was no obvious difference (P > 0.05). (3) Positive rates of serum biochemical parameters between the 2 groups within 72 hours after arrival at hospital: Group S AST 24 cases, ALT 18 cases, CK 42 cases, LDH 22 cases, Tbil 21 cases; Group C AST 20 cases, ALT 11 cases, CK 32 cases, LDH 18 cases, Tbil 17 cases. There was also no obvious difference (P > 0.05). (4) Positive rate of ECG: between the 2 group on arrival at hospital Group S 24 cases, Group C 19 cases. No obvious difference was shown (P > 0.05). (5) Fatality rates between the 2 groups: Group S 7.41% (4/54), Group C 6.00% (3/50), chi(2) = 0.082, P > 0.05. Conclusion: Acute mixed OP poisoning and single OP poisoning show no significant difference in clinical manifestations. The treatment measures for single OP poisoning also has good effect fo mixed OP poisoning.
