Worldwide, the cesarean section (c-section) rate is rising. Globally, regional anesthesia in the form of spinal anesthesia (SA) is considered the first choice in uncomplicated c-section cases for safe maternal and neonatal outcomes. This study aimed to ascertain knowledge, acceptance, and fears of SA among patients scheduled for c-section in a tertiary care hospital. ⋯ Not applicable.

Hypotension after induction of general anesthesia may lead to severe complications in elderly patients. This study investigated whether the respiratory variation of velocity time integral (ΔVTI) and peak velocity (ΔVpeak) of left ventricular outflow tract (LVOT) could predict hypotension after induction of general anesthesia in elderly patients. ⋯ ΔVTI of LVOT was a reliable predictor of hypotension after the induction of general anesthesia in elderly patients. ΔVpeak of LVOT should be used cautiously to predict hypotension after induction of general anesthesia due to nearly half of elderly patients in the gray zone.Trial registrationThis study was registered in the Chinese Clinical Trial Registry (registration number: ChiCTR2300077117).

High spinal block is a serious complication of spinal anesthesia. However, findings regarding its associated risk factors are inconsistent, and no studies have reported a relevant risk prediction score. We aimed to determine the risk prediction score for high spinal block in patients who were induced spinal anesthesia for cesarean delivery. ⋯ The combination of patient- and anesthesia-related predictors played an important role in the intermediate- and high-risk groups for high sensory spinal block. Addressing the modifiable risk factors-a GA < 35 weeks, an optimal dose of bupivacaine, and the experience level of the spinal block performer-could minimize the risk of high spinal block during cesarean delivery.

Observational Study
Application of ultrasound-guided inferior vena cava collapsibility measurement in volume assessment for patients undergoing single-shot spinal anesthesia in total hip arthroplasty.
To explore the value of ultrasound in volume assessment during the perioperative period of single-shot spinal anesthesia for total hip arthroplasty. A total of 100 patients undergoing elective surgery under spinal anesthesia at our hospital from January 2022 to January 2024 were selected. Transthoracic echocardiography was used to measure the diameter of the abdominal aorta (Ao) before anesthesia (T1), 10 minutes after anesthesia (T2), and 30 minutes after anesthesia (T3). ⋯ IVCe, IVCi, IVC-CI, and IVCe/Ao can predict volume reactivity before anesthesia. IVCi, IVC-CI, and IVCe/Ao predicted persistent hypotension in patients with spinal anesthesia after anesthesia, and IVCe/Ao showed the best predictive effect. Thus, IVCe/Ao is a reliable parameter for predicting persistent hypotension and assessing volumetric reactivity.
