Abstract:
Objective To evaluate the efficacy of ultrasound?guided transversus abdominis plane ( TAP) block with different concentrations of ropivacaine for analgesia after cesarean section. Methods A total of 120 parturients, aged 24-31 yr, of American Society of Anesthesiologists physical statusⅠ or Ⅱ, weighing 64-73 kg, at 35 to 41 week gestation, scheduled for elective cesarean section, were randomly di?vided into 3 groups ( n= 40 each) using a random number table: 0?25% ropivacaine group ( group Ⅰ) , 0?20% ropivacaine group ( groupⅡ) , and 0?15% ropivacaine group ( groupⅢ) . A patient?controlled an?algesia pump was connected at the end of surgery, and the corresponding concentration of ropivacaine 1?5 mg∕kg was injected into the bilateral TAP under the guidance of ultrasound in each group. Visual analogue scale score was maintained ≤3. The number of attempt and the number of patients requiring rescue analge?sic were recorded at 48 h after surgery. The occurrence of TAP block?related complications was observed and recorded. Results Compared with groupⅢ, the number of attempt and the number of patients requi?ring rescue analgesic were significantly decreased in Ⅰ and Ⅱ groups ( P<0?05 ) . Compared with groupⅡ, the number of attempt and the number of patients requiring rescue analgesic were significantly de?creased in group Ⅰ (P<0?05). No TAP block?related complications were detected in the three groups. Conclusion Ultrasound?guided TAP block with 0?25% ropivacaine is helpful in improving the analgesic efficacy after cesarean section without serious complications.
