供氧气管导管在麻醉苏醒室的应用研究
Application of oxygen-supply tracheal tubes in post anesthesia care unit
摘要
Abstract
Objective To observe the effect of oxygen-supply tracheal tubes in improving ventilation quality for patients with total intravenous anesthesia. Methods Ninety patients having the limb surgery under total intravenous anesthesia were randomly divided into three groups (each including 30 cases), all of them used No. 7 tracheal tube:group A with common tracheal tubes, group B with tracheal gas insufflation, and group C with oxygen-supply tracheal tubes. After operation the patients were sent to the Post-anesthesia Care Unit (PACU) with tracheal tubes. In the PACU, basic vital signs were recorded. After the patients restored autonomous respiration, they were supplied oxygen via tracheal tubes in different methods. When TOF T4/T1 ≥ 0.9, vital signs were recorded, and breathing parameters were observed and computed by the anaesthesia machine. Results There were no obvious differences in basic vital signs among the groups when the patients entered the PACU (P > 0.05). When TOF T4/T1 ≥ 0.9, HR and MAP of the groups A and B rose obviously as compared to the group C (P < 0.05), meanwhile, Ppeak, Ppla, Pmean and Raw of the groups A and B greatly increased as compared to the group C (P < 0.05); however, there were no obvious differences between the group A and the group B (P > 0.05). For RR and TV, there were no obvious differences among the three groups (P > 0.05). Conclusions During the the anesthesia recovery process of patients with the total intravenous anesthesia, oxygen-supply tracheal tubes are able to supply oxygen without any auxiliary breathing equipment such as T-tube, which is a necessary support to common tracheal tubes. It is of great clinical significance to protect airway of patients and reduce the work of breathing.关键词
