About

The purpose of this study is to determine the effects of Transversus Abdominis Plane Block on hemodynamic variables, anaesthetic and analgesic requirement, and quality of recovery in patients undergoing total abdominal hysterectomy

Full description

Pain is one of the main causes of the poor perioperative outcomes and pain management is the important part of perioperative period. Neuraxial blocks could provide adequate analgesia during and after abdominal surgery. However,neuraxial blocks have a lot of contraindicated situations and neuraxial anesthesia can easily induce hemodynamic abnormalities. Therefore, in most cases, the choice of anaesthetic management may be the general anesthesia. In addition to reduce the blood pressure and heart rate changes due to surgical stimulations, the large amount of opioids and anaesthetics may be required. Opioid related side effects can affect perioperative complications and postoperative quality of recovery. Transversus abdominis plane block is a new choice to reduce postoperative pain in abdominal surgery. Although its postoperative analgesic efficacy is well known, its effects on hemodynamic variables, anaesthetic and analgesic requirement is not clear. The main objective of this study is to estimate the effect of Transversus abdominis plane block on hemodynamic variables, anaesthetic and analgesic requirement and quality of recovery in patients undergoing total abdominal hysterectomy.
