Effect of Transversus Abdominis Plane Block Combined With Dexmedetomidine Infusion on the Prognosis in Elderly Patients Undergoing Abdominal Surgery

August 17, 2020 updated by: Yuming Peng, Beijing Tiantan Hospital
To compare the prognosis of elderly patients undergoing radical resection of colorectal cancer treated with general anesthesia and general anesthesia combined with transversus abdominis plane block and continuous infusion of dexmedetomidine. The incidence of postoperative delirium, postoperative acute pain moderately to severely and poor postoperative recovery were composite endpoints to determine the prognosis of patients.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
EXPERIMENTAL: Dex+TAPB group
Patients in Dex+TAPB group will receive the bilateral transversus abdominis plane block with 0.25% ropivacaine 20ml each side before anesthesia and combined with continuous infusion of dexmedetomidine during operation.
Procedure: Transversus abdominis plane block using ropivacaine
Before anesthesia, the ultrasound-guided bilateral transversus abdominis plane block using 0.25% ropivacaine was perdormed by anesthesiologist who is not involved in intraoperative management and postoperative follow-up and evaluate the effect after the block completed.
Drug: Dexmedetomidine
After finished the transversus abdominis plane block, then perform tracheal intubation and start the infusion of dexmedetomidine.
PLACEBO_COMPARATOR: Control group
Patients in control group will receive the bilateral transversus abdominis plane block with saline 20ml each side before anesthesia and don't receive the infusion of dexmedetomidine during operation.
Procedure: Transversus abdominis plane block using saline
Before anesthesia, the ultrasound-guided bilateral transversus abdominis plane block using saline was perdormed by anesthesiologist who is not involved in intraoperative management and postoperative follow-up and evaluate the effect after the block completed.
Drug: Saline
After finished the transversus abdominis plane block, then perform tracheal intubation and start the infusion of saline, dosage and infusion method of saline are consistent with dexmedetomidine.
