Ultrasound Guided Arterial Line Placement in Long Axis Versus Short Axis in Pediatric Patients

No results posted yet for this study

Summary

The use of ultrasound is becoming widespread to guide the placement of arterial lines for both vascular access and regional anesthesia in the field of anesthesia. Arterial line placement can be challenging, especially in the pediatric population. Frequently multiple attempts are required with relatively high failure rates. This can result in excessive needle punctures and extended OR times. A few studies have looked at the use of ultrasound to decrease OR time and increase success rates both in adult and pediatric populations. These studies compared the traditional palpation method with either short axis or long axis views of the vessel using ultrasound guidance. No study to date has compared short axis and long axis views for arterial line placement in either the pediatric or adult population. Our study compares success rates and OR times when long and short axis methods of arterial line insertion are employed in the pediatric population.

Conditions

  • General Anesthesia

Interventions

PROCEDURE

Arterial line placement

The following measures will be collected and compared. 1. Time (in seconds) required for successful placement of the arterial line. This is the time elapsed between either palpation or placement of ultrasound probe on the patient's wrist and the successful demonstration of arterial waveform on the anesthesia monitor. 2. number of attempts, defined as forward advancements of needle, required to cannulate the artery. 3. number of separate skin punctures. 4. number of arteries into which entry is attempted.
