Title of Thesis:

Quantitative assessment of haemodynamic changes following ultrasound guided regional anesthesia

Outline of the Thesis:

Background:

Ultrasound guided regional anesthesia has gained great popularity in clinical practice in the last several decades. The merits of ultrasound guided regional anesthesia, noninvasive, no radiation, direct visualization of the target nerve and surrounding structures, pre-determination of needle depth and angle, real time visualization of accurate needle insertion and local anesthetic spread, improved quality of block and higher success rates etc, have been widely acknowledged. Nowadays, varied techniques for both peripheral and neuraxial nerve blockades with the guidance of ultrasound are being explored and developed. However, blood flow assessment following ultrasound guided regional anesthesia, in which area, we did not find related reference article. This study is designed to utilize pulsed Doppler ultrasound to quantify the blood flow variations after ultrasound guided regional anesthesia.
