Permanent complications are uncommon. More scientific evidence is warranted to understand the precise mechanisms for this treatment modality. A larger organized clinical trial is desired to establish the efficacy of precentral stimulation.

We examined whether the use of real-time ultrasound guidance is superior to a landmark technique for femoral vein catheterization in children undergoing heart surgery. METHODS: Patients were prospectively randomized into 2 groups. In group LM, the femoral vein was cannulated using the traditional method of palpation of arterial pulse. In group US, cannulation was guided by real-time scanning with an ultrasound probe. The time to complete cannulation (primary outcome), success rate, number of needle passes, number of successful cannulations on first needle pass, and incidence of complications were compared between the 2 groups. RESULTS: Forty-eight pediatric patients were studied. The time to complete cannulation was significantly shorter (155 [46 -690] vs 370 [45-1620] seconds; P ϭ 0.02) in group US versus group LM. The success rate was similar in both groups (95.8%). The number of needle passes was smaller (1 [1-8] vs 3 [1-21]; P ϭ 0.001) and the number of successful cannulations on first needle pass higher (18 vs 6; P ϭ 0.001) in group US compared with group LM. The incidence of femoral artery puncture was comparable between the 2 groups. CONCLUSIONS: Ultrasound-guided cannulation of the femoral vein, in pediatric patients, when performed by senior anesthesia residents, is superior to the landmark technique in terms of speed and number of needle passes, with remarkable improvement in first attempt success.

We conducted a study to investigate this correlation between age and level of disc herniation, and to associate it with the magnitude of the Lumbar Lordotic Angle (LLA), as measured by Cobb's method. We followed retrospectively lumbosacral spine MRI's of 1419 patients with symptomatic disc herniation. Pearson's correlation was used in order to investigate the relationship between LLA, age, and level of disc herniation. Student's t-test was applied to assess gender differences. Young patients were found to have higher LLA (R = 0.44, P < 0.0001) and lower levels of disc herniation (R = 0.302, P < 0.0001), whereas older patients had higher level herniation in lower LLA group (mean LLA 28.6 • and 25.4 • ) and lower level herniation in high LLA group (mean LLA 33.2 • ). We concluded that Lumbar lordotic Cobb's angle and age can be predictors of the level of lumbar disc herniation. This did not differ among men and women (R = 0.341, P < 0.0001).
