To estimate the incidence of unwanted spontaneous responsiveness and burst suppression (BSupp) in patients undergoing state entropy (SE) and surgical pleth index (SPI)-guided total intravenous anesthesia (TIVA) with target-controlled infusion (TCI).
Observational, prospective, single-center study.
Operating room.
107 adult (<65 years) and elderly (≥65 years) women undergoing breast surgery.
Propofol-remifentanil TIVA-TCI-guided by SE for depth of anesthesia monitoring (target value 40-60) and SPI for antinociception monitoring (target value 20-50) without neuromuscular blockade.
Age; body mass index; American Society of Anesthesiologists physical status classification; concentration at the effect site of propofol (CeP) and remifentanil (CeR) at loss of responsiveness (LoR), median during anesthesia maintenance (MdM), and at return of responsiveness (RoR); propofol infusion duration; incidence of postoperative delirium (POD) with Confusing Assessment Method for the Intensive Care Unit.
During SE-SPI-guided TIVA-TCI, 13.1% of patients showed unwanted spontaneous responsiveness, whereas 45.8% showed BSupp. Unwanted spontaneous responsiveness was observed mainly in adults (p < 0.05), and higher CeP RoR (p < 0.05) was registered. BSupp was observed mainly in patients showing a lower CeP MdM (p < 0.01) and CeP RoR (p < 0.05). Unwanted spontaneous responsiveness and BSupp were not associated with significant differences in CeRs. An age-related hysteresis effect was observed, resulting in higher CeP LoR than CeP RoR (p < 0.001). 12.2% of patients showed POD. Only preoperative serum albumin was associated with increased likelihood of POD (p = 0.046).
The SE-SPI-guided TIVA-TCI did not prevent unwanted spontaneous responsiveness and BSupp. CeP RoR may be used as a proxy for anesthetic sensitivity.
评估在接受状态熵（SE）和手术容积指数（SPI）引导下的靶控输注（TCI）全静脉麻醉（TIVA）的患者中，非预期的自主反应性和爆发抑制（BSupp）的发生率。
观察性、前瞻性、单中心研究。
手术室。
107例接受乳房手术的成年（<65岁）和老年（≥65岁）女性。
丙泊酚-瑞芬太尼TIVA-TCI，以SE指导麻醉深度监测（目标值40-60），以SPI指导抗伤害感受监测（目标值20-50），不使用神经肌肉阻滞剂。
年龄；体重指数；美国麻醉医师协会身体状况分级；丙泊酚（CeP）和瑞芬太尼（CeR）在意识消失（LoR）时、麻醉维持期中位数（MdM）以及意识恢复（RoR）时效应部位的浓度；丙泊酚输注持续时间；采用重症监护病房谵妄评估方法评估的术后谵妄（POD）发生率。
在SE-SPI引导的TIVA-TCI期间，13.1%的患者出现非预期的自主反应性，而45.8%的患者出现BSupp。非预期的自主反应性主要在成年人中观察到（p<0.05），且记录到较高的CeP RoR（p<0.05）。BSupp主要在CeP MdM较低（p<0.01）和CeP RoR较低（p<0.05）的患者中观察到。非预期的自主反应性和BSupp与CeRs的显著差异无关。观察到与年龄相关的滞后效应，导致CeP LoR高于CeP RoR（p<0.001）。12.2%的患者出现POD。只有术前血清白蛋白与POD发生可能性增加相关（p=0.046）。
SE-SPI引导的TIVA-TCI未能预防非预期的自主反应性和BSupp。CeP RoR可作为麻醉敏感性的替代指标。
