A single-center, double-blinded, randomized controlled trial.
Perioperative care.
A total of 170 children undergoing otorhinolaryngologic surgery, aged 3-7 years, ASA physical status I or II were involved.
Patients were randomized to receive breathing training during the pre-operative visit (Training group) or to receive pre-operative visit only (Control group) the day before surgery.
Emergence delirium was measured by the Pediatric Anesthesia Emergence Delirium score during the anesthesia recovery time. Data regarding extubation time and post-anesthesia care unit stay time were collected.
Children who received breathing training during the pre-operative visit had a significantly lower incidence of emergence delirium than those who only underwent the pre-operative visit (10.4% vs. 35.1%, P < 0.001). The awakening time score and the maximum score in the post-anesthesia care unit were significantly lower in the training group compared with the control group [4.4 ± 3.4 vs. 6.9 ± 4.2, P < 0.001 and 5.0 (5.0) vs 7.0 (7.0), P = 0.001, respectively]. We found no differences in the extubation time and post-anesthesia care unit stay time between groups.
We concluded that breathing training based on video learning during the pre-operative visit in preschool children undergoing otorhinolaryngologic surgery could significantly decrease the incidence of emergence delirium.

单中心,双盲,随机对照试验。
围手术期护理。
共有170名儿童接受耳鼻喉手术,3-7岁,涉及ASA身体状况I或II。
患者被随机分配在术前访视期间接受呼吸训练(训练组)或仅在手术前一天接受术前访视(对照组)。
在麻醉恢复时间期间通过小儿麻醉出现谵妄评分来测量出现谵妄。收集有关拔管时间和麻醉后监护病房停留时间的数据。
术前访视期间接受呼吸训练的患儿出现谵妄的发生率明显低于仅接受术前访视的患儿(10.4%vs.35.1%,P<0.001)。训练组苏醒时间评分和麻醉后监护单元最高评分明显低于对照组[4.4±3.4vs.6.9±4.2,P<0.001和5.0(5.0)vs7.0(7.0),P=0.001,分别]。我们发现两组之间的拔管时间和麻醉后护理单元停留时间没有差异。
我们得出的结论是,在接受耳鼻喉手术的学龄前儿童的术前访视期间进行基于视频学习的呼吸训练可以显着降低出现谵妄的发生率。
