|Time Needed to Achieve a Successful Cannulation of the Femoral Artery in Pediatric Cardiac Surgery||Device: Ultrasound Other: Landmark||Not Applicable|
The insertion of percutaneous femoral catheter is the method of choice for arterial monitoring in pediatric patients undergoing cardiac surgery at American University of Beirut Medical Center. It is easier to access since it is a bigger vessel and matches better the aortic pressure immediately post initiation of bypass than the radial artery. Utilizing ultrasound in radial artery cannulation has been well described (1). A meta-analysis of 4 trials showed that, ultrasound guidance for radial artery catheterization improved first-pass success rate compared to the palpation method (2). Two of these trials were for pediatric patients where in one study ultrasound-guided radial arterial cannulation in 30 small children improved success rate with fewer attempts required with the ultrasound technique than with the traditional technique (3). However, in another study of 152 children under 12 years of age requiring radial artery cannulation, there were no statistically significant differences between the groups in time to successful cannulation, total number of attempts, number of successful cannulations during the first attempt, or in the number of cannulae used for catheterization (4). No previous study compared the use of ultrasound guidance vs landmark for femoral artery cannulation in the pediatric age group in particular for the teaching of anesthesia residents.
The hypothesis is that the use of ultrasound guidance by senior residents learning the technique of femoral artery catheterization is superior to the landmark technique.
The investigators will design a prospective randomized trial to compare the use of ultrasound guidance versus landmark technique in 110 children undergoing cardiac surgery. The inclusion criteria are ASA III or IV children under 12 years of age. Exclusion criteria are hematoma or infections at the potential site of insertion, need for emergency surgery, and hemodynamic instability.
The risks to subjects include no more than the usual risks of arterial cannulation (infection and hematoma formation). Adverse events will be monitored, reported and treated appropriately.
Privacy and confidentiality will be respected. Data will be kept under lock with the primary investigator.

Patients in group Ultrasound will have their femoral arterial lines inserted under the guidance of US. The Ultrasound equipment used is a SonoSite 180 PLUS with an L25/10- to 5-MHz linear array transducer (SonoSite, Inc., Bothell, WA)
Other Name: SonoSite 180 PLUS
No Device is used. Patients in group Landmark will have their femoral line inserted using the blinded, external landmark-guided technique. After localization of the femoral artery by identifying the pulse in the femoral triangle immediately distal to the inguinal ligament.
- the time needed to achieve a successful cannulation of the femoral artery. [ Time Frame: The time to successful cannula insertion will be calculated from the time of skin penetration until proper placement of the catheter is confirmed by an arterial waveform seen on the monitor after connecting the catheter to a transducer ]
