Effect of ultrasound monitoring of diaphragmatic function on respiratory recovery during resuscitation in patients undergoing head and neck surgery under general anesthesia
[Objective]To explore the effect of ultrasound monitoring of diaphragmatic function on respiratory recovery during resuscitation in patients undergoing general anesthesia for head and neck surgery.[Methods]A total of 120 patients who were hospitalized in Chashan Hospital of Dongguan from January 2021 to January 2023 and successfully underwent head and neck surgery were selected as the research objects.According to different monitoring schemes,the subjects were randomly divided into control group(routine monitoring,no ultrasound evaluation,n=30),experimental group 1(ultrasound evaluation of upper airway,n=340),experimental group 2(ultrasound evaluation of diaphragm,n=30),experimental group 3(ultrasound evaluation of diaphragm and upper airway,n=30).The pulse oxygen saturation(SpO2)at T0(before induction),T1(immediately after tracheal extubation),T2(2 min after tracheal extubation),T3(5 min after tracheal extubation),T4(15 min after tracheal extubation)and T5(before leaving the resuscitation room)were compared among the four groups.The oropharyngeal diameter of the experimental group 1 and the experimental group 3 was compared.The diaphragm mobility of the experimental group 2 and the experimental group 3 was compared.The number of interventions received by patients in each group at T1-T5 were compared.The PACU stay time and the time from PACU to extubation were compared among the groups.[Results]At T2-T5,SpO2 in experimental group 2 and experimental group 3 was higher than that in control group.At T3-T4,SpO2 in experimental group 1 was higher than that in control group.At T2-T3,SpO2 in experimental group 2 and experimental group 3 was higher than that in experimental group 1(P＜0.05).Compared with T0,SpO2 was significantly decreased at T1-T5 in control group and experimental group 1,and at T1-T4 in experimental group 2 and experimental group 3(P＜0.05).The intervention rate of experimental group 1 at T1 and T4 was significantly higher than that of the control group.The intervention rate of experimental group 2 and experimental group 3 at T1 and T2 was significantly higher than that of the control group.The intervention rate of experimental group 2 and experimental group 3 at T4 and T5 was significantly lower than that of the control group.The intervention rate of experimental group 2 and experimental group 3 at T1 was significantly higher than that of experimental group 1(P＜0.05).There was no significant difference in PACU residence time between group 2 and group 3(P＞0.05).The PACU stay time in the control group was significantly longer than that in the experimental group 1,experimental group 2 and experimental group 3(P＜0.05).[Conclusion]In the recovery period of general anesthesia patients undergoing head and neck surgery,ultrasound was used to monitor the diaphragm function of patients.The visualization of diaphragm movement by ultrasound can effectively show the recovery degree of diaphragm function in patients during anesthesia recovery period,and provide a reference for anesthesiologists to predict respiratory depression before clinical manifestations of patients,so as to take intervention measures,improve the respiratory function of patients undergoing head and neck surgery during general anesthesia recovery period,and reduce the stay time of monitoring treatment room after anesthesia.
