Abstract:
One hundred and fifty ASA Ⅰ-Ⅱ infants scheduled to undergo surgery on unilateral inguinal region,were randomly assigned to 3 groups with 50 in each group.In groups Ⅰ and Ⅱ puncture was performed at traversus abdominis plane under ultrasound-guidance,0.4 or 0.5/kg of 0.25％ ropivacaine was injected respectively.In group Ⅲ the triangle of Petit was positioned through palpating and then 0.5 ml/kg of 0.25％ ropivacaine was injected.HR,RR,SpO2,PETCO2,expired sevoflurane concentration and BIS value at the time of entering the operation room (T1),incision of skin (T2),pulling hernia sac (T3),ending the surgery (T4),waking (T5),the number of pressing the analgesia pump after operation were recorded.The results showed that HR at T2 and T3 of groups Ⅰ and Ⅱ was lower than group Ⅲ (P ＜ 0.05).The were significant differences in case numbers of insufficient intraoperative analgesia among 3 groups(x2 =10.500,P =0.005).The CHEOPS scores and the number of pressing analgesia pump after operation in groups Ⅰ and Ⅱ were lower than those in group Ⅲ (x2 =7.230,P =0.027).Results indicate that ultrasound-guided transversus abdominis plane block is safer and more effective than conventional method for operations of inguinal region in infants; it may reduce dose of local anesthetics and postoperative use of analgesics.
