Abstract:
Objective:To analyze the effects of different mask ventilation modes on hemodynamics and gastric air intake in children with tonsillectomy and adenoid resection under general anesthesia.Methods:Eight-six children with tonsillectomy from January 2020 to December 2022 treatment in the Children′s Hospital Affiliated to Capital Institute of Pediatrics were enrolled and they were divided into the control group and the test group by random numbers table, 43 cases in each group. When inducing mask ventilation under general anesthesia, the control group used manual control ventilation mode, while the experimental group used pressure control volume assurance ventilation mode. The hemodynamics, respiratory parameters, antral area, and gastric air intake in the two groups at before mask ventilation (T 0), 60 s (T 1), 120 s (T 2), 180 s (T 3), and at the end of surgery (T 4) were compared between the two groups. Results:Compared with T 0, the heart rate (HR) and mean arterial pressure (MAP) of the two groups at T 1 and T 4 were reduced, but there were no statistical differences between the groups ( P>0.05). At T 1, T 2, and T 3, the peak airway pressure and average airway pressure in the experimental group were lower than those in the control group, T 1: (11.09 ± 2.36) cmH 2O (1 cmH 2O = 0.098 kPa) vs. (13.42 ± 2.15) cmH 2O, (4.98 ± 1.26) cmH 2O vs. (6.52 ± 1.73) cmH 2O; T 2: (11.32 ± 2.04) cmH 2O vs. (13.16 ± 2.37) cmH 2O, (5.11 ± 1.37) cmH 2O vs. (6.20 ± 1.55) cmH 2O; T 3: (11.25 ± 2.17) cmH 2O vs. (13.08 ± 2.29) cmH 2O, (4.93 ± 1.29) cmH 2O vs. (6.17 ± 1.48) cmH 2O, there were statistical differences ( P<0.05). After face mask ventilation, the area of the gastric antrum in the test group was smaller than that in the control group, and the incidence of gastric intake was lower than that in the control group: (2.17 ± 0.63) cm 2 vs. (2.51 ± 0.85) cm 2, 9.30% (4/43) vs. 34.88% (15/43), there were statistical differences ( P<0.05). Conclusions:Tonsillectomy and adenoid resection under general anesthesia in children, the use of pressure control volume to ensure ventilation mode during mask ventilation induced by anesthesia can maintain low respiratory parameters and reduce the incidence of gastric intake.
