The relevance of dorsalis pedis artery blood pressure and brachial artery blood pressure in supine position has been studied, in the state of epidural anesthesia and shock recovery, in different age groups, to investigate the clinical value of perioperative monitoring dorsalis pedis artery blood pressure.100 orthopedic and obstetrics patients undergoing epidural anesthesia, and 80 hypovolemic shock (trauma, hemorrhagic shock) with recovery, were collected. The left dorsalis pedis artery and brachial Blood pressure were monitored by the multi-function monitor in all patients, during the period of pre-anesthesia, anesthesia satisfaction and post-surgery, and the shock and the recovery process in supine position; 150 selected-surgery patients, included 50 children, 50 young and middleaged cases and 50 old age cases, also were collected. The left dorsalis pedis artery blood pressure and brachial blood pressure has beenmonitored in all cases. There was no significant difference between the SBP and DBP of the left arteria dorsalis pedis and the SBP and DBP of brachial artery, during the time of pre-anesthesia and anesthesia satisfaction. But compared to the brachial artery, SBP and DBP of the left arteria dorsalis pedis were higher, in 9mmHg and 7mmHg each (P <0.01), and the blood pressure of the two parts was linear correlation in these three time point. There was high relevance between the dorsalis pedis artery blood pressure and brachial Blood pressure during the period of shock and the recovery using of vasoactive drugs. There was no significant difference between the dorsalis pedis artery blood pressure and the brachial blood pressure in the childrenÂ’s group; but SBP and DBP of the left arteria dorsalis pedis were higher than the brachial artery, in 20mmHg and 5mmHg in the young and middle-aged group (P <0.01, P <0.05), and in 21 mmHg and 6 mmHg in the old aged group (P <0.01). The circumference of distal lower leg and upper arm were almost equal in different ages patients, and the dorsalis pedis artery blood pressure and brachial Blood pressure were significantly correlated (P <0.01). The results showed that there was a high positive correlation between the dorsalis pedis artery blood pressure and the brachial blood pressure in the state of spinal anesthesia, recovery and in different ages.Monitoring the dorsalis pedis artery blood pressure can reflect the hemodynamic changes timely and objectively. This method can substitute monitoring the brachial blood pressure when necessary, and has an important clinical value.
