Brief Summary

Sciatic nerve blocks are frequently used for anesthesia or analgesia for surgery of the lower legs. Currently, if ultrasound is used to find the sciatic nerve, the leg must be raised to locate the nerve with the ultrasound probe on the back of the thigh. In pediatric surgery, the patients are anesthetized (asleep) before the block is given. It is difficult for one person to administer the sciatic nerve block using this method. We would like to identify the sciatic nerve using ultrasound on the side of the thigh and its location to the adjacent structures.

Conditions

Sciatic Nerve AH; Peripheral Nerves US

Keywords

Sciatic Nerve; Peripheral Nerve Block; Lower extremity surgery; Local Anesthesia; Ultrasound guided nerve blocks

Outcome Measures

Primary Outcomes (1)

• The primary objective is to describe the appearance of the sciatic nerve and its location in relation to adjacent anatomic structures using ultrasound from the lateral mid-thigh position.

  10 minutes

Secondary Outcomes (1)

• A secondary objective is to describe correlations between any of the measured variables and the patient's mid-thigh circumference or weight.

  10 minutes

Study Arms (1)

1

Pediatric Patients of ages 11-17

Other: Observation of the Sciatic Nerve

Interventions

Observation of the Sciatic Nerve OTHER

Ultrasound will be used to determine the location of the Sciatic Nerve using a lateral mid-thigh approach.

Also known as: Sciatic Nerve location, Peripheral Nerve Blocks

Study Population

Pediatric patients

You may qualify if:

• Males or females 11 to 17 years old.
• Patients undergoing lower extremity surgery who are scheduled to have a sciatic nerve block as part of the anesthetic.
• Parental/guardian permission (verbal consent) and child assent. Note: if you record ANY PHI, you will need to obtain written consent since HIPAA requires written authorization for use of PHI.

You may not qualify if:

• None
