: To investigate whether ultrasound (US)-guided femoral vein (FV) and inferior vena cava (IVC) measurements obtained before spinal anesthesia (SA) can be utilized to predict SA-induced hypotension (SAIH) and to identify risk factors associated with SAIH in patients undergoing non-obstetric surgery under SA. : This was a prospective observational study conducted between November 2021 and April 2022. The study included 95 patients over the age of 18 with an American Society of Anesthesiologists (ASA) physical status score of 1 or 2. The maximum and minimum diameters of FV and IVC were measured under US guidance before SA initiation, and the collapsibility index values of FV and IVC were calculated. Patients with and without SAIH were compared. : SAIH was observed in 12 patients (12.6%). Patients with and without SAIH were similar in terms of age [58 (IQR: 19-70) vs. 48 (IQR: 21-71; = 0.081) and sex (males comprised 63.9% of the SAIH and 75.0% of the non-SAIH groups) ( = 0.533). According to univariate analysis, no significant relationship was found between SAIH and any of the FV or IVC measurements. Multiple logistic regression analysis revealed that having an ASA class of 2 was the only independent risk factor for SAIH development ( = 0.014), after adjusting for age, sex, and all other relevant parameters. : There is not enough evidence to accept the feasibility of utilizing US-guided FV or IVC measurements to screen for SAIH development in patients undergoing non-obstetric surgery under SA. For this, multicenter studies with more participants are needed.
: 目的：探讨椎管内麻醉（SA）前超声（US）引导下股静脉（FV）和下腔静脉（IVC）测量值是否可用于预测 SA 引起的低血压（SAIH），并确定接受非产科手术 SA 患者中与 SAIH 相关的危险因素。: 这是一项于 2021 年 11 月至 2022 年 4 月期间进行的前瞻性观察性研究。研究纳入了 95 名年龄在 18 岁以上、ASA 身体状况评分为 1 或 2 的患者。在开始 SA 前，采用 US 引导测量 FV 和 IVC 的最大和最小直径，并计算 FV 和 IVC 的塌陷指数值。比较发生和未发生 SAIH 的患者。: 12 例（12.6%）患者出现 SAIH。发生和未发生 SAIH 的患者在年龄[58（IQR：19-70）比 48（IQR：21-71； = 0.081）和性别（男性分别占 SAIH 组和非 SAIH 组的 63.9%和 75.0%）（ = 0.533）]方面无显著差异。单因素分析显示，SAIH 与 FV 或 IVC 的任何测量值均无显著相关性。多变量逻辑回归分析显示，ASA 分级 2 是 SAIH 发生的唯一独立危险因素（ = 0.014），校正年龄、性别和所有其他相关参数后仍如此。: 尚无足够证据支持接受 US 引导的 FV 或 IVC 测量值用于筛查接受非产科手术 SA 的患者中 SAIH 的发生。为此，需要开展更多参与者的多中心研究。
