Summary
The aim of this study is to assess the efficacy of a bilateral TFP block in parturients
undergoing cesarean delivery (CD) by evaluating postoperative opioid consumption and numeric
rated pain scores in two groups (TFP block with saline (control) and TFP block with local
anesthetic (treatment)). Women (American Society of Anesthesiologists physical status Class
1-3) at term gestation with singleton pregnancies undergoing an elective CD under spinal
anesthesia at the South Health Campus will be consented to participate in the study. Patients
will be randomly assigned using a computer-generated table of random numbers to two groups.
Group allocations will be concealed. All patients will receive spinal anesthesia with spinal
Morphine according to our institutional protocol. At the end of surgery, randomized patients
will receive either ultrasound-guided bilateral TFP blocks with 0.25% bupivacaine with 2.5
mcg/ml epinephrine 40 ml total or maximum 2.5 mg/kg (Group 1) or 40 mL saline (Group 2) by 2
anesthesiologists experienced in performing this block.
