简要总结
Epidural analgesia for abdominal surgeries provides numerous advantages for both neonates and children. The anatomical identification of the intervertebral space to access the epidural space is not constantly easy this is due uncertainty of the direction of the needle angle and the difficulty to estimate the epidural depth in spite of the skill of the operator. This can lead to more puncture attempts, inducing more pain or discomfort and even failure of epidural access.
Pre-procedure neuraxial ultrasound (US) imaging facilities the identification of the chosen intervertebral space, the depth of the epidural space and so the selection of best point and angle for the needle insertion
详细描述
The aim of this study is to evaluate the efficacy of prepuncture ultrasonography to facilitate epidural block in pediatric patients undergoing elective urological operations compared with the conventional anatomical landmark technique

盲法说明
Patients will be randomly assigned to 2 equal groups (ultrasonography and palpation; 55 subjects in each group) using the permuted block randomization method with randomly selected block sizes of 4 and 6. The group allocation codes were concealed in sequentially numbered, opaque, sealed envelopes that were opened only after assessing the eligibility and obtaining the consent from the parents

研究组 & 干预措施
palpation group
In lateral decubitus position, the conventional palpation technique will be used to detect the epidural space. The midline will be identified by palpation of the spinous processes. Through the Tuffier's line, L5 spine then, the two intervertebral spaces (L3-4 and L2-3) will be detected and the middle of each intervertebral space will be marked with selection of the widest space.
After sterilization of the patient's skin the needle will be inserted to detect the epidural space by using loss of resistance to saline
Ultrasonography group
In lateral decubitus position, a curved array probe will be utilized to scan the sacrum in the longitudinal paramedian plane, then the probe will be moved upwards to detect the L5-S1, L4-5, L3-4 and L2-3 intervertebral spaces then turned 90º to the transverse plane and used to scan L3-4 and L2-3 spaces inside the 2 spaces, midline will be detected by noting the site of spinous processes with selection of the space with the best sonographic image quality. Then skin surface at the middle of the long and short axis of the probe will be marked horizontally. If the 2 spaces have the same image quality, L2-3 space will be chosen for the entrance of epidural needle. After sterilization of the patient's skin the needle will be inserted to detect the epidural space by using loss of resistance to saline
