Abstract:
Objective:To observe the application effect of dexmedetomidine combined with esketamine nasal drops in pediatric flexible bronchoscopy (referred to as bronchoscopy) surgery with spontaneous respiration retained.Methods:A total of 96 children undergoing bronchoscopy in the Changsha Hospital for Maternal & Child Health Care from May 2022 to December 2023 were selected and divided into the dexmedetomidine nasal drop group (group D, 47 cases) and the dexmedetomidine combined with esketamine nasal drop group (group DE, 49 cases) by random number table method. The mean arterial pressure (MAP), heart rate (HR), blood oxygen saturation (SpO 2) and respiratory rate (RR) of the two groups were observed before nasal drops (T 0), 30 minutes after nasal drops (T 1), 5 minutes after surgery started (T 2), and 10 minutes (T 3), 30 minutes (T 4), 60 minutes (T 5) and 120 minutes (T 6) after surgery. The separation anxiety and mask cooperation scores at T 1, modified Aldrete scores and Pediatric Anesthesia Emergence Delirium Scale (PEAD) scores at T 3-T 6 were evaluated; the number of children with PEAD score>10 was recorded, as well as the time to postoperatively take food and clear water. Results:There was no statistically significant difference in MAP and HR at T 0 between the two groups (all P>0.05); the MAP and HR of Group DE at T 1-T 6 were significantly higher than those of group D (all P<0.05). There was no statistically significant difference in SpO 2 and RR between the two groups within the group or between the groups at each time point (all P>0.05), while the incidence of hypoxemia (SpO 2≤92%) in group D at T 2 was significantly higher than that in group DE ( P<0.05). The separation anxiety and mask cooperation scores of group DE at T 1 were significantly better than those of group D ( P<0.05). The modified Aldrete scores of group DE at T 3, T 4 and T 5 were significantly higher than those of group D (all P<0.05). The PEAD score of group DE at T 3 was significantly lower than that of group D ( P=0.001); there was no statistically significant difference in PEAD scores between the two groups at T 4, T 5 and T 6 (all P>0.05), and no child in either group had PEAD scores>10 at T 4, T 5 and T 6. The time to take clear water and food in group DE was significantly earlier than that in group D (all P<0.05). Conclusions:In pediatric bronchoscopy surgery with spontaneous respiration retained, dexmedetomidine combined with esketamine nasal drops can more effectively relieve children′s separation anxiety, meet surgical needs, improve recovery quality, shorten the postoperative time to take food, and better implement the concept of enhanced recovery after surgery (ERAS) compared with dexmedetomidine alone.
