N/V
-definitions of N/V
-nausea: vague, intensely disagreeable sensation of sickness or "queasiness" and is distinguished from anorexia
-vomiting: often follows nausea, as does retching (spasmodic respiratory and abdominal movements); distinguish from regurgitation (effortless reflux of liquid, food, or stomach contents) and rumination (chewing and swallowing of food that's regurgitated voluntarily after meals)
168
what is the sensation of emesis controlled by?
-brainstem vomiting center within medulla
-stimulated by 4 afferent inputs:
*afferent vagal fibers from the GI viscera: rich in serotonin 5-HT3 receptors stimulated by biliary or GI distention, mucosal or peritoneal irritation or infections
*fibers of the vestibular system: increase concentration of histamine H1
*increase CNS center (amygdala): certain sights, or emotional experiences may induce vomiting (pts w/chemo
169
where is the chemoreceptor trigger zone associated with N/V?
-what type of receptors are rich in this area?
-what is this area stimulated by?
-located outside the BBB (area postrema of the medulla)
-rich in opioid, serotonin 5HT3, neurokinin 1 (NK1), & Dopamine D2 receptors
-stimulated by drugs & chemotherapeutic agents, toxins, hypoxia, uremia, acidosis, & radiation therapy
170
N/V
-s/s (6)

2. acute onset of severe pain and vomiting: peritoneal irritation, acute gastric or intestinal obstruction, or pancreaticobiliary disease
3. persistent vomiting: pregnancy, gastric outlet obstruction, gastroparesis, intestinal dysmotility, psychogenic disorders, and CNS or systemic disorders
4. vomiting that occurs in the morning before breakfast: pregnancy (common), uremia, ETOH intake, and increased ICP
5. vomiting immediately after meals: bulimia or psychogenic causes
6. vomiting of undigested food one to several hours after meals: gastroparesis or a gastric outlet obstruction
171

N/V
-antiemetic meds (6)
1. serotonin 5-HT-receptor antagonists
2. corticosteroids
3. neurokinin receptor antagonists
4. dopamine antagonists
5. antihistamines and anticholinergics
6. cannabinoids
183
N/V
-antiemetic meds: serotonin 5-HT-receptor antagonists
ondansetron, granisetron, dolasetron, and palonosetron are effective in preventing chemotherapy, and radiation-induced emesis when initiated prior to treatment
-due to its prolonged halflife and internalization of the 5-HT3-receptor, palonosetron is superior to other 5-HT2-receptor antagonists for the prevention of acute and delayed chemotherapy-induced emesis from moderately or highly emetogenic chemotherapeutic regimens
-although 5-HT3-receptor antagonists are effective as single agents for the prevention of chemotherapy-induced nausea and vomiting, their efficacy is enhanced by combination therapy w/ a corticosteroid (dexamethasone) and NK1-receptor antagonist
-serotonin antagonists increasingly are used for the prevention of postoperative N/V because of increased restrictions on the use of other antiemetic agents (such as droperidol)
184
N/V
-antiemetic meds: corticosteroids
-(dexamethasone) have antiemetic properties, but the basis for these effects is unknown
-these agents enhance the efficacy of serotonin receptor antagonists for preventing acute and delayed N/V in patients receiving moderately to highly emetogenic chemotherapy regimens
185
N/V
-antiemetic meds: neurokinin receptor antagonists
-aprepitant, fosaprepitant, and rolapitant are highly selective antagonists for NK1-receptors in the area postrema
-used in combination w/ corticosteroids and serotonin antagonists for the prevention of acute and delayed N/V w/ highly emetogenic chemotherapy regimens
-netupitant is another oral NK1-receptor antagonist that is administered in a fixed-dose combination w/ palonosetron
0combined therapy w/ a neurokinin-1 receptor antagonist prevents acute emesis in 80-90% and delayed emesis in more than 70% of patients treated w/ highly emetogenic regimens
186
N/V
-antiemetic meds: dopamine antagonists
-phenothiazines, butyrophenones, and substituted benzamides (prochlorperazine, promethzaine) have antiemetic properties that are d/t dopaminergic blockage as well as their sedative effects
-high doses of these agents are associated w/ antidopaminergic side effects, including extrapyramidal reactions and depression
-w/ the advent of more effective and safe antiemetics, these agents are infrequently used, mainly in outpatients w/ minor, self-limited sx
-the chemotherapy were already being given dexamethasone, an NK1-receptor antagonist, and a 5-HT3 antagonist, olanzapine was superior to placebo for the prevention of acute and delayed nausea
187
N/V
-antiemetics meds: antihistamines and anticholinergics (meclizine, dimenhydrinate, transdermal scopolamine)
-may be valuable in the prevention of vomiting arising from stimulation of the labyrinth (motion sickness, vertigo, and migraines)
-they may induce drowsiness
-a combination of oral vitamin B6 and doxylamine is recommended by the American College of Obstetricians and Gynecologists as first-line therapy for nausea and vomiting during pregnancy
188
N/V
-antiemetic meds: cannabinoids
-marijuana has been used widely as an appetite stimulant and antiemetic
-pure delta-9-tetrahydrocannabinol (THC) is the major active ingredient in marijuana and the most psychoactive and is available by prescription as dronabinol
-in doses of 5-15 mg/m2, oral dronabinol is effective in treating nausea associated w/ chemotherapy, but is associated with CNS SE in most patients
-some states allow the use of medical marijuana w/ a clinician's certification
-strains of medical marijuana w/ different proportions of various naturally occurring cannabinoids (primarily THC and cannabidiol (CBD)) can be chosen to minimize its psychoactive effects
189
Hiccupping
-clinical findings (evaluation of the patient w/ persistent hiccups should include):
-what to do if cause remains unclear?
detailed neurologic exam, serum creatinine, liver chemistry tests, and a chest radiograph
-CT or MRI of the head, chest, and abd, echocardiography, and upper endoscopy
190
Hiccupping
-essentials of dx (what benign or not; what do persistent hiccups indicate; how hiccups can impact mechanical vent pts)
-usually benign and self-limiting annoyance
-persistent hiccups: sign of serious underlying illness
-pt w/ mechanical ventilation: hiccups can trigger a full respiratory cycle --> respiratory alkalosis
191
Hiccupping
-causes of benign, self-limiting hiccups
-gastric distension (carbonated beverage, air swallowing, overeating), sudden temp changes (hot then cold liquids, hot then cold shower), ETOH ingestion, & states of heightened emotion (excitement, stress, laughing)
192
Hiccupping
-causes of recurrent/persistent hiccups
over 100 causes including GI, CNS, CV, and thoracic disorders
193
Hiccupping
-simple remedies for acute benign hiccups
-irritation of nasopharynx: tongue traction, lifting the uvula w/ a spoon, catheter stimulation of the nasopharynx, or eating 1 teaspoon of dry granulated sugar
-interruption of the respiratory cycle: breath holding, Valsalva maneuver, sneezing, gasping (fright stimulus), or rebreathing into a bag
-Stimulation of the vagus: carotid massage
-Irritation of the diaphragm: holding knees to chest or by continuous positive airway pressure during mechanical ventilation
-relief of gastric distention: belching or insertion of NG tube
194
Hiccupping
-several drugs have been promoted as being useful in tx of hiccups
-chlorpromazine, 25-30mg orally or IM (most commonly used)
-anticonvulsants (phenytoin, carbamazepine), benzodiazepines (lorazepam, diazepam), metoclopramide, baclofen, gabapentin, and occasionally general anesthesia
195
