Objectives: To evaluate the security of general anesthesia for different class of elective surgery in children merger with mild to moderate tipper respiratory infection (URI). Methods: 207 cases of children who undergoing general anesthesia for elective surgery, were divided into three groups, non-URl group (unURl group, n=140), mild URI group (miURl group, n=50L moderate URI group (moURl group, n=17), according to the preoperative sylnptoms and signs of the upper respiratory tract infection. Monitoring and recording the respiratory-related complications of children through pcrioperativc and postoperative period. The article compares the differences in the incidence of various complications between groups, according to hierarchical classification of surgery. Results: (1) Compared with unURl group and miURl group, the incidence of secretions and cough in moURl group were increased (P 〈0.05), during perioperative and postoperative period in surgical Ill-IV class children. The incidence of respiratory complications between the three groups showed no significant difference in surgical Ill-IV class children during perioperative and postoperative period (P〉0.05). (2) The incidence of laryngospasm, bronchospasm, breath holding (Time≥30s) and SpO2〈90% showed no significant difference between the three groups (P〉0.05). (3) Compared with the perioperative period the incidence of complications in postoperative period overall downward, but no statistically significant difference between the groups (P〉0.05). Conclusions: It is relatively safe to implemented tracheal intubation general anesthesia for the children merger with mild URI or moderate URI in Ill-IV surgical class. But surgical IN-IV class children with moderate URI need a comprehensive assessment between the risks and benefit relationship before general anesthesia. 相似文献
