Monitoring blood pressure under general anesthesia in animals is important to prevent hypotension and poor tissue perfusion. Thirteen sheep were enrolled to evaluate the accuracy of the petMAP, a portable non-invasive blood pressure (NIBP) monitor. Animals were anesthetized with midazolam, fentanyl, ketamine, propofol and maintained with isoflurane in oxygen for ovariectomy. Invasive and non-invasive (petMAP) blood pressure measurements were recorded simultaneously every 5 minutes. Agreement between IBP and NIBP was assessed by evaluation of bias and 95% limits of agreement (LOA) using the Bland-Altman method and correlation coefficient. None of the measurements met the criteria for good agreement between invasive and non-invasive readings established by the Association for the Advancement of Medical Instrumentation. Systolic blood pressure readings obtained at the left thoracic limb site and mean blood pressure at the right pelvic limb site met the bias and LOA criteria established by the American College of Veterinary Internal Medicine.
在动物全身麻醉期间监测血压对于预防低血压和组织灌注不良很重要。选取13只绵羊来评估便携式无创血压（NIBP）监测仪petMAP的准确性。动物用咪达唑仑、芬太尼、氯胺酮、丙泊酚麻醉，并用异氟醚和氧气维持麻醉以进行卵巢切除术。每5分钟同时记录有创和无创（petMAP）血压测量值。使用Bland-Altman方法和相关系数通过评估偏差和95%一致性界限（LOA）来评估有创血压（IBP）和无创血压（NIBP）之间的一致性。没有任何测量值符合医疗仪器促进协会制定的有创和无创读数之间良好一致性的标准。在左胸肢部位获得的收缩压读数以及在右后肢部位获得的平均血压读数符合美国兽医内科学会制定的偏差和LOA标准。
