Application of transversus abdominis plane block combined with rectus sheath block for peritoneal dialysis catheter placement / 中华肾脏病杂志

ABSTRACT

Objective To discuss the efficacy and safety of transversus abdominis plane block (TAPB) combined with rectus sheath block (RSB) for peritoneal dialysis catheter placement.Methods Thirty patients,ASA Ⅰ or Ⅱ,body mass index (BMI) 18-30 kg/m2,were scheduled for elective peritoneal dialysis catheter placement.They were randomly divided into three groupslocal anesthesia group (group L),ultrasound-guided TAPB group (group T),ultrasound-guided TAPB combined with RSB group (group TR).Mean arterial blood pressure (MAP) and heart rate (HR) were recorded before (T0) and after (T1) anaesthesia,the beginning of operation (T2) and abdomen-closing (T3),6 h (T4),12 h (T5),24 h (T6) after surgery.The consumption of local anesthetic during the surgery,dezocine after the surgery,the score of visual analogue scale (VAS) during rest and movement at T2-T6 and the adverse reactions were recorded.Results At T3,MAP and HR in group L and group T were higher than those in group TR (P ＜ 0.05).At T4 and T5,MAP and HR in group L were higher than those in group T and group TR (P ＜ 0.05);the consumption of local anesthetic ropivacaine in group L and group T were more than that in group TR (P ＜ 0.05);the consumption of local anesthetic ropivacaine and dezocine in group L were more than that in group T (P ＜ 0.05).The VAS score was significantly lower in group T and group TR at T3,T4,T5 compared with that in group L (P ＜ 0.05).There were no adverse reactions.Conclusion Ultrasound-guided TAPB combined with RSB is safe and efficacious in patients undergoing peritoneal dialysis catheter placement.
