Abstract:

Objective To observe the application of the controlled respiratory persistence monitor designed based on the principle of rhythmic temperature variations in artificial airways among different populations and in various artificial airways, and to discuss the feasibility and efficacy of monitoring controlled respiration persistence, and to provide a new method for the clinical respiratory monitoring. Methods A total of 60 adult patients scheduled for general anesthesia, and 30 pediatric patients aged from 1 to 3 years old, classified as American Society of Anesthesiologists (ASA) Ⅰ-Ⅱ, were selected. A total of 60 adult patients were randomly divided into adult tracheal intubation (ATI) group and adult laryngeal mask(ALM) group, and there were 30 cases in each group. Additionally, 30 pediatric patients aged from 1 to 3 years old were regarded as pediatric tracheal intubation (CTI) group. After induction of general anesthesia, the patients in CTI and ATI groups were underwent tracheal intubation, while the patients in ALM group were given a laryngeal mask inserted and were connected to the anesthesia machine for mechanical ventilation. Whether or not the device could detect the respiratory rate (RR)of the patients in various groups was observed; the RR detected by the device and the frequency set on the anesthesia machine in various groups were compared. All the patients in three groups were simulated three common clinical scenarios of continuous respiration changes before surgery: disconnection of the breathing circuit, failure to switch from manual to mechanical control on the anesthesia machine, and slow air leakage in the breathing circuit. The ways to report the alert and start time of the atarm by the monitors were compared. Results The controlled respiratory persistence monitor was able to detect the RR of the patients in three groups, and there was no significantly difference between the RR detected by the device and the frequency set on the anesthesia machine (P>0.05). In the simulated scenarios of common respiratory persistence changes, all the patients in three groups received an artificial voice alarm signaling “Attention, breathing has stopped.”, which was acknowledged. There was no significant difference in the start time of alarm of the controlled respiratory persistence monitor between ATI group and ALM group (P>0.05). Compared with the start time of alarm of the patients in the same group across different scenarios, compared with slow air leakage in the breathing circuit, the start time to alarm for circuit disconnection and failure to switch from manual to mechanical control was shorter (P<0.05). Conclusion The clinical application of the controlled respiratory persistence monitor device designed based on the principle of detecting rhythmic temperature variations within artificial airways is feasible and effective in different populations and artificial airways. This device offers a new method for monitoring the respiratory continuity and ensuring the respiratory safety during surgery.
