ABSTRACT
Objective To compare the analgesic effect of the ultrasound-guided modified-fascia iliaca compartment block with ultrasound-guided fascia iliaca compartment block injection in the treat-ment of elderly patients with hip fracture.Methods Sixty elderly patients with hip fracture,17 males and 43 females,falling into ASA physical status Ⅱ or Ⅲ,were randomly divide into two groups (n=30 each):ultrasound-guided modified fascial iliaca compartment block group (group M)and ultra-sound-guided fascial iliaca compartment block group (group F).The patients in group M received M-FICB using ultrasound-guided injection of 0.4% ropivacaine 5 ml in obturator nerve,15 ml in the fas-cial iliac space.The patients in group F received ultrasound-guided injection of 0.4% ropivacaine 20 ml in the fascial iliac space.FICB or MFICB was performed 20 min before epidural anesthesia in group F or group M respectively.The time of ultrasound-guided nerve block was recorded,and the onset time of femoral nerve,lateral femoral cutaneous nerve and obturator nerve block were recorded in the two groups.Visual analogue pain scores (VAS)were recorded before nerve block (T0 ),after nerve block,10 min (T1 ),20 min (T2 ),placing spinal anesthesia position (T3 ),and postoperative 24 h (T4 ).Results The onset time of obturator nerve block in group M was significantly shorter than that in group F [(4.1±1.4)min vs (10.1 ±3.9)min,P <0.05].The time of ultrasound-guided nerve block has no difference between the two groups [(2.2 ± 0.5 )min vs (2.1 ± 0.5 )min].Compared with group F,the VAS scoress at T1-T3 were lower in group M (P <0.05).Compared with T0 ,the VAS scores at T1-T4 decreased in both groups (P < 0.05 ).Conclusion Ultrasound-guided fascia iliaca compartment block is more effective in reducing the VAS scores during the supine position and reducing postoperative pain.
ABSTRACT
Objective To evaluate the safety and efficacy of super mini-percutaneous nephrolithotomy (SMP) by ultrasound-guided renal access in pediatric with renal calculus.Methods From May to August 2015, 20 pediatric patients with upper tract stones underwent the SMP by ultrasound guidance.The patients aged 11-144 months , median age 31.5 months, The stone size ranged 0.8-2.5 cm, mean(1.48 ±0.59) cm.Among the 20 children, single pelvis stones were in 8, multiple stones in 10 and upper ureter stones in 2.All patients had no previous surgery treatment.The SMP system consists of a F6.0 -7.5 nephroscope and a modified F12-14 access sheath with suction-evacuation function.Nephrostomy tract dilation was performed up to F12-14 and lithotripsy procedure was performed by using pneumatic lithotripter.Nephrostomy tube or double J stent was placed only if clinically indicated.Results The stone size was 0.8-2.5 cm ,mean (1.48 ± 0.59)cm.Among the 20 children, there were 8 patients with single pelvis stone, 10 with multiple stones and 2 with upper ureter stones.All the patients were completed successfully without surgery conversion.Mean operative time ranged 6-40 minutes ,mean(17.6 ± 11.6) minutes.The stone free rate was 100％ after the evaluation in the postoperative day.The hemoglobin drop was 2-16 g/L,mean (7.6-± 4.1) g/L.No major complications occurred, neither patient required transfusion.The tubeless PCNL without double J stents and nephrostomy tubes placed were achieved in all patients.Only 14 patients had a ureter catheter placement for one day.The average hospital stay ranged 1-4 days, mean (2.4 ± 0.8) days.Conclusions SMP could be a safe and effective treatment for kidney stone up to 2.0 cm in pediatric cases with advantages of short recovery time, high stone free rate and no catheter placement.SMP could be the ideal procedure for children with upper urinary tract calculus.
