The aim of this pragmatic approach to retrospective observational study was to identify the end-tidal concentration of sevoflurane which was associated with optimal surgical conditions (i.e., absence of any movement, coughing and straining) in 127 pregnant sheep. Optimal surgical conditions were observed in 90% of the ewes with an end-tidal concentration of sevoflurane of 2.4 Vol-% [95% CI: 2.2; 2.8] during minimal-mild nociceptive stimuli (placement of arterial catheter, bladder catheter, shaving), with 4.4 Vol-% [95% CI: 4.0; 5.2] during maternal laparotomy and hysterotomy and with 4.4 Vol-% [95% CI: 3.9; 5.8] during subsequent manipulation of the uterus and fetal surgery.
本回顾性观察研究采用实用方法，旨在确定 127 只妊娠绵羊的呼气末七氟醚浓度，使其与最佳手术条件（即无任何运动、咳嗽和紧张）相关。在最小轻度伤害性刺激（放置动脉导管、膀胱导管、剃毛）时，呼气末七氟醚浓度为 2.4 体积%[95%CI：2.2；2.8]时，90%的母羊观察到最佳手术条件，在母体剖腹术和子宫切开术时为 4.4 体积%[95%CI：4.0；5.2]，在随后的子宫和胎儿手术操作时为 4.4 体积%[95%CI：3.9；5.8]。
