ABSTRACT
Objective To evaluate the efficacy of mid-axillary approach to transversus abdominis plane (TAP) block in each abdoninal and back region.Methods Twenty patients of both sexes,aged 18-64 yr,with body mass index of 20-27 kg/m2,of American Society of Anesthesiologists physical status Ⅰ or Ⅱ,scheduled for elective laparoscopic cholecystectomy,who had expected operation time <1 h,were enrolled in the study.Ultrasound-guided TAP block was performed on the left side via the mid-axillary line with 0.25% levobupivacaine 0.5 ml/kg.TAP block was assessed by cold stimulation (75% alcohol) and acupuncture in each abdominal and back region (the left side of the body was divided into 19 regions using the anatomical landmarks on the body surface).The positive condition in each region at 20 min after administration was recorded.Results The regions in which the positive rate ≤5% were 11,14,17 and 18 regions.The regions in which the positive rate >5%-20% were 8,15 and 19 regions.The regions in which the positive rate >20%-50% were 12,13 and 16 regions.The regions in which the positive rate >50%-70% were 1 and 4 regions.The regions in which 70% < the positive rate < 95% were 7,9 and 10 regions.The regions in which the positive rate ≥ 95% were 2,3,5 and 6 regions.Conclusion Mid-axillary approach to TAP block is effective in the left middle-lower regions of the anterior abdominal wall,however,it is ineffective in the left upper region between mid-axillary and posterior axillary lines and in the low back region.
