Objective To observe the effectiveness and safety of ultrasound-guided subcostal transverses abdominis plane block with dexmedetomidine and low-concentration ropivacaine in elder vaginal hysterectomy. Methods Forty scheduled for vaginal hysterectomy (ASAⅠ～Ⅱ)were randomly assigned to 2 groups. All patients received spinal anesthesia, and ultrasound-guided subcostal transverses abdominis plane block then, Group Ⅰ: 0.5 μg/kg dexmedetomidine and 0.2% ropivacaine 20 mL for each side, and saline was used for Group Ⅱ. HR、MAP SpO₂ and NTI scale were recorded at the time points of pre-anesthesia(T₀), confirmation of anesthesia plane (T₁), beginning of surgery (T₂), pulling uterus (T₃), surgery end(T₄). Effect of dragging reaction, POCD and delirious and degree of comfort and degree of satisfaction of patients were valuated. Results The general condition did not differ between the two groups(P>0.05). Compared to Group Ⅰ, HR of Group Ⅱ at the time point of T3 was significant lower(P<0.05), number of patients with excellent dragging reaction of Group Ⅰ was significant higher (P<0.05)and patients of Group Ⅰ were more comfortable and satisfied than patinents of Group Ⅱ(P<0.05). Conclusion Ultrasound-guided subcostal transverses abdominis plane block with dexmedetomidine and low-concentration ropivacaine is effective and safe for vaginal hysterectomy in elderly female.
