Randomized Controlled Trial Comparative StudyThe efficacy of ultrasound-guided transversus abdominis plane block in patients undergoing hysterectomy.
The study objective of this prospective, double-blind randomised controlled study was to evaluate the efficacy of ultrasound guided transversus abdominis plane (TAP) block and bupivacaine infiltration of the skin and subcutaneous tissue of the wound in patients undergoing hysterectomy. Patients were randomly allocated to three groups: a control group (n = 18) and TAP block group (n = 18) received bilateral TAP blocks with saline and bupivacaine respectively, and an infiltration group (n = 19) received skin and subcutaneous wound tissue infiltration with bupivacaine at the end of surgery. ⋯ Total tramadol consumption was significantly lower in the TAP group than in the other groups at all time points. We concluded that ultrasound-guided TAP block reduced rest and movement pain after total abdominal hysterectomy and was more effective than superficial wound infiltration for postoperative pain management.
