这项研究研究了不同的目标导向液体治疗类型如何影响机器人辅助腹腔镜妇科手术期间的低血压和液体输注。他们使用颈动脉校正流量时间(FTc)和潮气量刺激脉压变化(VtPPV)检查患者的容量状态和反应性。研究结果表明,各种液体治疗目标显着影响术中低血压和液体需求。然而,该研究仅采用单侧颈动脉超声评估,可能忽略左右颈动脉之间血流的生理或病理变化。这种方法选择引起了人们的关注,因为指南建议进行双边测量以进行更全面的评估。缺乏双边评估可能会影响研究的可靠性和可重复性。证明单侧测量方法的合理性对于验证临床发现至关重要。未来的研究应采用双侧颈动脉超声评估或为单侧测量提供详细的基本原理,以增强临床评估的鲁棒性和准确性。
This study examined how different goal-directed fluid therapy types affected low blood pressure and fluid infusion during robot-assisted laparoscopic gynecological surgery. They used carotid corrected flow time (FTc) and tidal volume stimulation pulse pressure variation (VtPPV) to check the patient\'s volume status and responsiveness. The findings indicated that various fluid therapy targets significantly influence intraoperative hypotension and fluid requirements. However, the study exclusively employed unilateral carotid ultrasound assessments, potentially overlooking physiological or pathological variations in blood flow between the left and right carotid arteries. This methodological choice raises concerns as guidelines recommend bilateral measurements for a more comprehensive evaluation. The lack of bilateral assessments could affect the study\'s reliability and reproducibility. Justifying the unilateral measurement approach is essential for validating clinical findings. Future research should adopt bilateral carotid ultrasound assessments or provide a detailed rationale for unilateral measurements to enhance the robustness and accuracy of clinical evaluations.
