Important Documents (Protocol, Consent Forms, Data collection form)

Procedure for LUS step-by-step at CHOP

• Place order on EPIC: NICU-Performed Research Ultrasound

• Bring up the patient on the worklist on the Ultrasound machine-choose patient

• No need to put patient ID on first clip 

• Use LUNG preset: Marker top left, loop time: 5 secs, depth 3 cm. XRES off.

• Specify marker on image: Right lung - Upper; Right lung - Lower; Right lung-Lateral

• Specify marker on image: Left lung - Upper; Left lung - Lower; Left lung-Lateral

• Machine: Philips CX50

• Probe: L15-7 (Hockey Stick)

• For LUS in delivery room and at 12 hours: only scan the contralateral lung to the CDH

• For pre-extubation LUS: Scan both lungs

• End exam.

Scanning

• Scanning: We scan in the longitudinal axis. 
Tip of Hockey stick pointing 12 o’clock (towards the head; tail of probe towards the lower body). 

• We divide the chest and indicate on each clip the corresponding position of scanning: Only one clip and one M-mode acquisition per quadrant (no need for repeated clips):

Right Lung:

A)   
Right Upper Anterior (along mid-clavicular line) – Clip sliding from clavicula to nipple line, followed by one M-Mode acquisition.

B)   Right Lower Anterior (along mid-clavicular line) - Clip sliding from nipple line to costal margin, followed by one M-Mode acquisition.

C)   Right Lateral (along mid-axillary line) - Clip sliding from axilla to costal margin (where you visualize the lung-diaphragm interface), followed by one M-Mode acquisition.

Left lung:

A)   Left Upper Anterior (along mid-clavicular line) - Clip sliding from clavicula to nipple line, followed by one M-Mode acquisition.

B)   Left Lower Anterior (along mid-clavicular line) - Clip sliding from nipple line to costal margin, followed by one M-Mode acquisition.

C)   Left Lateral (along mid-axillary line) - Clip sliding from axilla to costal margin (where you visualize the lung-diaphragm interface), followed by one M-Mode acquisition.

If Left CDH: 

• LUS 1 and 2: Right chest scanning (3 right zones clips + 3 right zones M-Modes)

• LUS 3 (pre-extubation): Both chest scanning (6 zones clips + 6 zones M-Modes)

If Right CDH: 

• LUS 1 and 2: Left chest scanning (3 left zones clips + 3 left zones M-Modes)

• LUS 3 (pre-extubation): Both chest scanning (6 zones clips + 6 zones M-Modes)
