Q

Chest tube bubbling normal vs abnormal

A

Gentle, continuous bubbling in suction control unit is normal

Bubbling in suction control
Intermittent = bad (suction too low, increase it)
Continuous = good (document)

Bubbling in water seal
Intermittent = good (document)
Continuous = bad (leak –needs tape)

Bubbling in leak gauge or in water seal chamber is not normal UNLESS the pt has pneumothorax in which case gentle intermittent bubbling in water seal chamber is expected until lung has fully expanded

Q

Intussusception

A

An intestinal obstruction due to bowel folds (like a telescope) causing increase in bowel pressure, vomiting due to pyloric muscle spasms (but NOT projectile vomiting). Produces blood and mucus in stool, looks like red jelly, a sausage shaped right sided mass on palpation is expected. Anticipate air enema (pneumatic enema) or hydrostatic (saline) enema to relieve obstruction/diagnose.

Q

Hirschsprung’s disease

A

Potentially fatal complication is enterocolitis which can lead to sepsis, presents as fever, lethargy, explosive foul-smelling diarrhea, and worsening distension of abdomen.

Q

Classic symptom of pyloric stenosis

A

projectile vomiting of non-bilious vomit

Hypertrophy of pyloric muscle causes postprandial projectile vomiting due to obstruction at gastric outlet. Palpate olive shaped mass to the right of the umbilicus. Vomiting is non-bilious (whatever is eaten is vomited) and leads to progressive dehydration and results in hypokalemic metabolic alkalosis. Hemoconcentration due to dehydration results in elevated hematocrit and BUN.

A

1st gen: diphenhydramine
2nd gen: loratadine, cetirizine

For allergy symptoms :runny nose, itchy/watery eyes, sneezing. Also used for Motion sickness and urticaria —hives.
Block H1 receptors which reduces effect of histamine in body.

1st gen side effects are more severe: sedation, anticholinergic, photosensitivity
Remember anticholinergic SE: can’t pee, can’t see, can’t spit, can’t shit.

207
Q

Corticosteroids (respiratory)

A

For respiratory —locally acting. Either inhalers or intranasal.
Beclomethasone, mometasone, budesonide, fluticasone. Use for asthma, rhinitis. Decrease inflammation locally.

Bronchodilator with steroid: bronchodilator administered first, wait 5 min, then corticosteroid.

208
Q

Leukotriene receptor antagonist

A

Montelukast, zafirlukast

Used in asthma and exercise induced bronchoconstriction. Decrease effect of leukotrienes which reduces airway inflammation and bronchoconstriction

Dextromethorphan: suppresses cough reflex in medulla. SE: dizziness and sedation at high doses.

210
Q

Bronchodilators

A

Beta2 Adrenergic Agonists: Albuterol and salmeterol
Used in asthma, COPD, alone or in combination with glucocorticoid or anticholinergics like iprotropium. Bind to beta2 receptors in the lungs (2 lungs) and result in bronchodilation, opening airways.

SE: nervousness, tremor, chest pain, palpitations.
