Correlation Between Dorsalis Pedis and Radial Arterial Invasive Blood Pressures During Anesthesia Induction in Neurosurgical Patients

Anesthesiologists need to understand the specific difference between dorsalis pedis arterial(DPA) pressure and the more commonly used radial arterial(RA) pressure When blood pressure monitoring at DPA. Generally, the systolic blood pressure measured in DPA is significantly higher than that in RA, with little difference of diastolic blood pressure and mean artery pressure in two sites. However, there is no specific study on the difference between them, and it is not clear how the diagnosis and treatment threshold should be adjusted when relying on DPA blood pressure measurement to guide treatment. The intraoperative blood pressure of patients is in the normal range in most cases. The purpose of this study is to analyze the correlation of different blood pressure stratification (RASBP90-109mmHg,110-129mmHg,130-149mmHg) of DPA-RA in the normal range to understand the correlation of DPA-RA in different blood pressure ranges, to provide a reference for clinical decision-making and hemodynamic management.

invasive blood pressure monitoring

Diagnostic Test

radial artery and dorsalis pedis artery intubated with BD Insyte-W 22G artery puncture needle under local anaesthesia

Primary outcomes

  1. DPA-RA invasive blood pressure

    Time frame: During anesthesia induction

    All DPA-RA blood pressure dates are Separate analyzed in the following three intervals: Group1 (RASBP 90-109mmHg), Group1 (RASBP 110-129mmHg), Group1 (RASBP 130-149mmHg).The correlation and consistency of each group were analyzed
