Objective To discuss oral nursing frequency of patients undergoing orally mechanical ventilation in order to ensure the oral cleanness of patients with the least oral nursing frequency and prevent the occurrence of ventilator associated pneumonia (VAP). Methods 36 patients undergoing orally me-chanical ventilation were randomly divided into groupA, B, C and D with 9 cases in each group, which all adopted 0.5% of pevidone iodine solution for oral nursing, time intervals of oral nursing were 4 hours, 6 hours, 8 hours and 12 hours. After the oral care and oral care before the next oropharyngeal samples for se-mi-quantitative bacterial colony counts, bacterial strain identification were obtained. The incidence rate of VAP was also compared and the results underwent χ2 test. Results Significant difference was seen in bacterial colony counts, especially during the time interval of 6 hours and 12 hours. No significant differ-ence was seen in incidence of VAP between the 4 groups. Conclusions The desirable frequency of oral nursing was every 6 hours on the premise of prevention of VAP.

Objective To investigate the prevention of the antelocation of nursing intervention to constipation in patients with acute myocardial infarction(AMI).Methods 70 AMI patients were divided randomly into the test group and control group with 35 patients in each group.The control group received the AMI usual care and drugs;the test group received the antelocation of nursing intervention to constipation besides the usual care and drugs.Results The death rate and the incidence of abdominal distension,abdominal pain,anxiety,and complication of the patients in the test group were lower than those of the patients in the control group(P<0.05).Conclusion The antelocation of nursing intervention to constipation can decrease the death rate of AMI patients.
