An Anesthesia Resident’s Prayer

Now I lay me down to sleep

I pray this pager does not beep

Please no risky extubations

Please no lengthy explanations

Please no 4AM calls for c/section

Please no swallowed razors in corrections

In this county, please no riots

Keep all the guns locked up and quiet

Keep the drunks out of their cars

Keep rabble-rousers behind bars

Keep all jigsaws out of hands

Keep all the Nattys in their cans

Keep all the rusty knives in blocks

Let all the crack stay formed in rocks

Let all the brains stay mass effectless

Give all the semi-urgents breakfast

Let every epidural work

Let no vascular disasters lurk

Let nobody’s water break

Let nobody’s RLQ ache

Let me not hear that timeout bell

Let not one fetus have decels

Let no heart failure be end stage —

Beep beep beep...

“This is anesthesia, returning a page...”

Anaphylaxis updates part 2- Empty Ventricle Syndrome

Patients with anaphylaxis should not suddenly sit, stand, or be placed in the upright position. Instead, they should be placed on the back with their lower extremities elevated or, if they are experiencing respiratory distress or vomiting, they should be placed in a position of comfort with their lower extremities elevated. This accomplishes 2 therapeutic goals: 1) preservation of fluid in the circulation (the central vascular compartment), an important step in managing distributive shock; and 2) prevention of the empty vena cava/empty ventricle syndrome, which can occur within seconds when patients with anaphylaxis suddenly assume or are placed in an upright position. Patients with this syndrome are at high risk for sudden death. They are unlikely to respond to epinephrine regardless of route of administration, because it does not reach the heart and therefore cannot be circulated throughout the body

Lumbar and thoracic epidural in Pediatrics-Technical aspect

The midline approach is most commonly used. The ligamentum flavum is considerably thinner and less dense in infants than in older children and adults. This makes recognition of engagement in the ligament more difficult and requires both extra care and slower, more deliberate passage of the needle to avoid subarachnoid puncture. The angle of approach to the epidural space is slightly more perpendicular to the plane of the back than in older children and adults, owing to the orientation of the spinous processes in infants and small children. The loss of resistance technique should be used, but only with saline, not air. There are several reports of venous air embolism in infants and children when air was used to test for loss of resistance Use a short (5 cm) 18-gauge Tuohy needle and a 20- or 21-gauge catheter in infants and children. Epidural kits specifically for infants and children are available Maximum of 0.4 mg/kg/hr of bupivacaine after the initial block is estab...
