APPENDIX G n Skills<br />
STEP 6. Observe the epiglottis and then the vocal<br />
cords. External laryngeal manipulation<br />
with backward, upward, and rightward<br />
pressure (BURP) may be helpful for<br />
better visualization.<br />
STEP 7.<br />
Insert the endotracheal tube not more than<br />
2 cm (1 inch) past the cords.<br />
STEP 8. Carefully check placement of the tube by bag<br />
ventilation, observing lung inflations, and<br />
auscultating the chest and abdomen with<br />
a stethoscope. Confirm correct placement<br />
of the tube by the presence of CO 2<br />
. A chest<br />
x-ray exam is helpful to assess the depth<br />
of insertion of the tube (i.e., mainstem<br />
intubation), but it does not exclude<br />
esophageal intubation.<br />
STEP 9. If endotracheal intubation is not accomplished<br />
within 30 seconds or in the same<br />
time required to hold your breath before<br />
exhaling, discontinue attempts, ventilate<br />
the patient with a bag-mask device, and<br />
try again.<br />
STEP 10. Secure the tube. If the patient is moved, tube<br />
placement should be reassessed.<br />
STEP 11. Attach a CO 2<br />
detector to the secured<br />
endotracheal tube between the adapter and<br />
the ventilating device to confirm the position<br />
of the endotracheal tube in the trachea.<br />
STEP 12. If not already done, attach a pulse oximeter<br />
to one of the patient’s fingers (intact<br />
peripheral perfusion must exist) to measure<br />
and monitor the patient’s oxygen saturation<br />
levels and provide an immediate assessment<br />
of therapeutic interventions.<br />
Needle Cricothyrotomy<br />
STEP 1. Assemble and prepare oxygen tubing by<br />
cutting a hole toward one end of the tubing.<br />
Connect the other end of the oxygen tubing<br />
to an oxygen source capable of delivering<br />
50 psi or greater at the nipple, and ensure<br />
the free flow of oxygen through the<br />
tubing. Alternatively, connect a bag mask<br />
by introducing a 7.5 mm endotracheal<br />
tube connector to a 3 cc syringe wtih the<br />
plunger removed.<br />
STEP 2. Place the patient in a supine position.<br />
Have an assistant restrict the patient’s<br />
cervical motion.<br />
STEP 3. Attach a 12- or 14-gauge over-the-needle<br />
cannula to a 5-ml syringe (16-18 gauge for<br />
infants and young children).<br />
STEP 4. Surgically prepare the neck, using antiseptic<br />
swabs.<br />
STEP 5. Palpate the cricothyroid membrane anteriorly<br />
between the thyroid cartilage and<br />
the cricoid cartilage. Stabilize the trachea<br />
with the thumb and forefinger of the nondominant<br />
hand to prevent lateral movement<br />
of the trachea during the procedure.<br />
STEP 6. Puncture the skin in the midline with the<br />
cannula attached to a syringe, directly over<br />
the cricothyroid membrane.<br />
STEP 7. Direct the cannula at a 45-degree angle<br />
caudally, while applying negative pressure<br />
to the syringe.<br />
STEP 8. Carefully insert the cannula through the<br />
lower half of the cricothyroid membrane,<br />
aspirating as the needle is advanced. The<br />
addition of 2-3 cc of saline to the syringe<br />
will aid in detecting air.<br />
STEP 9. Note the aspiration of air, which signifies<br />
entry into the tracheal lumen.<br />
STEP 10. Remove the syringe and withdraw the<br />
needle while gently advancing the cannula<br />
downward into position, taking care not to<br />
perforate the posterior wall of the trachea.<br />
STEP 11. Attach the jet insufflation equipment to the<br />
cannula, or attach the oxygen tubing or 3 mL<br />
syringe (7.5) endotracheal tube connector<br />
combination over the catheter needle hub,<br />
and secure the catheter to the patient’s neck.<br />
STEP 12. Apply intermittent ventilation either by<br />
using the jet insufflation equipment, or<br />
using your thumb to cover the open hole<br />
cut into the oxygen tubing or inflating with<br />
an ambu bag. Deliver oxygen for 1 second<br />
and allow passive expiration for 4 seconds.<br />
Note: Adequate PaO 2<br />
can be maintained for only<br />
around 30 to 45 minutes, and CO 2<br />
accumulation<br />
can occur more rapidly.<br />
