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 />
