OBJECTIVE
The present study aimed to assess the occurrence of trigeminocardiac reflex (TCR) during Le Fort I osteotomies.
STUDY DESIGN
This case-crossover study included 25 Le Fort I osteotomy candidates without systemically compromising conditions. Mean arterial blood pressure and pulse rate values were recorded before downfracture (DF) (MABP1, PR1), during DF (MABP2, PR2), and after DF (MABP3, PR3). The data were analyzed using repeated measure ANOVA tests (alpha = 0.05).
RESULTS
PR1 and PR3 were significantly higher than PR2 (P < .001). MABP2 value was significantly lower compared with MABP1 and MABP3 values (P < .001). PR2 and MABP2 showed a mean decrease of 6.5% and 9.7% compared with PR1 and MABP1, respectively.
CONCLUSION
Different values have been suggested for TCR. Considering the limitations, the present study may suggest a revision of the values or descriptions for TCR, at least in maxillofacial Le Fort I osteotomy.
目的
本研究旨在评估勒福Ⅰ型截骨术中三叉神经心脏反射（TCR）的发生情况。
研究设计
本病例交叉研究纳入了25例无全身系统性疾病的勒福Ⅰ型截骨术候选患者。记录下颌骨切开前（DF）（平均动脉血压1、心率1）、下颌骨切开期间（平均动脉血压2、心率2）和下颌骨切开后（平均动脉血压3、心率3）的平均动脉血压和心率值。使用重复测量方差分析检验（α = 0.05）对数据进行分析。
结果
心率1和心率3显著高于心率2（P < .001）。平均动脉血压2值显著低于平均动脉血压1和平均动脉血压3值（P < .001）。与心率1和平均动脉血压1相比，心率2和平均动脉血压2平均分别下降了6.5%和9.7%。
结论
对于TCR提出了不同的值。考虑到局限性，本研究可能提示至少在颌面勒福Ⅰ型截骨术中对TCR的值或描述进行修订。
