Objective Observation devoted to the clinical therapeutic effect of smectite enema for babies and infants with rotaviralenter and to the nursing for them.Method. 160 cases were divided at random into two groups. one (80)under abservation,and the other(80)under conrtol. Both groups were treated by correction of dehydration and phenol poisoning and replaced with electrolytes,but noantibiotics and antidiarrheals were applied. The group under observation received therapies,microecological,antiviral .Smectite per os andenema,while the group under control received all the enema while for smectite enema.As result the defervescence averaged our at 1.57 ± 0.79 days for the former and 1.71 ± 0.73 days for the latter (T = 0.345, P > 0. 50), wherein there was noable discrepancy betweenthem.The acerae periods of diarrheaceasing and stool shaping.dehydration correction,and the course of disease were 2.15 ± 1.25 days,1.55±0.61 days and 2.9±1.12days , respectively , for the group under observation and3.05±2.16 days (T=2.105,P<0.05), 2.15± 1.04 days (T=2.231, P<0.05) and 3.55± 1.23days (T= 2.251, P<0.05) for the group under control,hence there appearednotable discrepancids between them. Conclusion In the average time of diarrhea ceasing and stool shaping dehydration correction and the course of disease there were notable discrepancies between the group of infantile diarrhea under smectite enema treatment and that not .Therecovery superiority of the group under observation to the group under control has justified a marked therapeutic effect of smectite enema forrotaviral enteritis, special attention should yet be paid to the young sufferers'posture for ,the speed,amount,depth and retention time of ,enema .
