Quiz 2 - Modules 5 & 6 Flashcards
How Breathing Occurs
- diaphragm contacts, moves down, makes thoracic cavity bigger
- increases volume and decreases pressure
- diaphram relaxes, moves up
- decreases volume and increases pressure
- If two areas of different pressure communicate, gas will move from area of higher pressure to area of lower pressure
Chest Tube Thoracostomy
placing a hollow plastic tube between the ribs and into the chest to drain fluid or air from around the lungs in pleural space
* reestablish intrapleural pressure
* promote lung expansion and restore adequate oxygenation
* drains for hemo/pneumothorax, pleural effusion
* want to remove air/fluid promptly
* prevent air/fluid from returning
* restore negative pressure
Pneumothorax
- Air between pleural space
- Occurs from central line placement, chest surgery, trauma to chest wall, traumatic intubation, mechanical ventilation
- Chest tube placement in upper thoracic cavity towards apex of the lungs
Hemothorax
- Blood in pleural space
- Occurs from chest surgery, central line placement, chest trauma
- Chest tube placement towards lower aspect of thoracic cavity towards base of the lung
Pleural Effusion
Transudate or exudate in pleural space
* Transudate: clear fluid from CHF, malnutrition, renal or liver failure
* Exudate: cloudy fluid with cells and proteins from TB and pneumonia
Chest Tube Placement Check-Off
- consent
- correct placement - CXR
- sutured in place
- airtight dressing
- local anesthetic
- supplemental O2
- monitor for hypotention with loss of fluids
- need thoracotomy tray: larger tubes for liquid, smaller for air
- pleural vac for drainage
- positioning dependent on air/fluid
Disposable 3 Chamber System
- Drainage collection
- Water seal
- Suction chamber: one for wet and one for dry
Water Seal Chamber
- Tube from patient in 2 cm of water
- Prevents air and fluid from coming back into pleura
- Tidals with respirations: normal fluctuations that increase with inspiration and decrease with expiration (opposite on ventilator)
- No tidals: tube may be kinked or clamped
- Bubbling: air leak, can clamp in different places to find it
Collection Chamber
- Keep upright below patient’s chest
- Assess color in drainage, report excessive
- Mark right on unit q1 hr every 24 hrs then q8 hrs - do not empty
- Encourage frequent position changes and coughing
Wet Suction
- For harder secretions that need to be drained
- Fill suction control chamber with 20 cm of water
- Degree of suction is set by water level
- Gentle bubbles: normal
Dry Suction
- No water column
- Suction monitor is below
- Dial control on side of unit
- Balances wall suction
Care Considerations with Chest Tubes
- Assess for subq emphysema: collection of air in tissues under the skin, can threaten airway
- Assess for resp status, drainage, occlusive dressing, connections are taped, tubing is free of kinks, no infection at site
Tension Pneumothorax
- S/S: trachial deviation towards pneumo, absent breath sounds on one side, JVD, resp distress, asym lung expansion, cyanosis, low BP/shock, organs get pushed
- Never clamp tube unless necessary: replacing unit or finding air leak
- Do not strip or milk tubing since it generated extreme negative pressure
Emergency Equiptment for Chest Tube
- 2 Kelly clamps
- 1 vaseline gauze
- 4x4 gauze
- New drainage system
- Sterile water: 250mL container
Dislodged Chest Tube
- Cover with sterile gauze and tape it on 3 sides to allow air to escape - can cause tension pneumo
Chest Tube Removal
- Indications: Improved resp status, symmetrical rise and fall of chest, bilateral breath sounds, decreased chest tube drainage, absence of bubbling, improved CXR findings
- Assess breath sounds, RR, O2 levels, pain before and after
- Meds 30 mins prior
- Allow patient to bare down to prevent air from entering pleural space
- Site secured with occlusive dressing and heavy weight stretch tape
- CHR placed to ensure lung is fully inflated
Respiratory Artificial Airways
- For patients with decreased level of consciousness and airway is at risk for obstruction or become obstructed
- Maintains airway patency
- Aids in removal of secretions
- Risk for infection and airway injury
- Clean technique for oral airway, sterile for endotrach and trach
- Need to stay in correct position
Oropharyngeal Airway
- Used to keep upper airway patent when at risk of being obstructed by tongue or secretions
- Extends from teeth to oropharynx - maintains tongue in normal position
- Measuring: corner of patient’s mouth to angle or jaw below the ear
- If too small: tongue will not stay positioned in anterior part of mouth
- Too large: push tongue towards epiglottis and obstruct airway
- Triggers gag reflex
- To insert: curved part goes upwards until reaches back of the mouth, then is rotated 180 degrees
Nasopharyngeal Airway
- Keeps upper airway patent
- Inserted through nares and extend to pharynx
- Measured from nose to angle of jaw
- No gag reflex, for patients that are alert
Endotrachial Tube
- Used to administer mechanical ventilation, relieve upper airway obstruction, protect against aspiration, or clear copious amounts of secretions
- Short term, not more than 14 days, put risk of infection and airway injury
- Placed either through nose or mouth past epiglottis and vocal cords into the trachea and down when it bifurcates into bronchi
- Use Laryngoscope to visualize patient anatomy, has light in it
- Size determined by age and size of patient
- Adults will have cuff that is inflated with air after insertion to prevent air from leaking around the tube and prevent oral and gastric secretions from being aspirated
Laryngeal Mask Airway
- Used for paramedics or other less experienced providers, fast and accurate placement regardless of circumstances
- Less gastric distention, not induce aspiration
- Good for when patient does not need to be intubated for long time or placement of ET tube not feasible
Tracheostomy Tube
- Used to establish a surgical airway via tracheotomy
- Placed below level of larynx – unable to speak
- May be permanent or temporary
- indications: replace ET tube, mechanical vent, acute or chronic airway obstruction, copious secretions
Nurse’s Role in Intubation
- Check and assemble equipment
- Hand equiptment to provider
- Check pulse ox
- Secure tape or ET holder to prevent deviation
- CXR and ABG
- Confirm tube position via auscultation, bilateral chest rise, tube locator at teeth (20-25cm), CO2 detector - pH sensitive and will turn purple to yellow
- False positives whenwhen gastric contents, mucus, epi come in contact – will permanently change to yellow and not fluctuate
Stabilizing ETT
- Use tape or prepackaged ET tube holder with Velcro
- Assess resp status every 2 hrs
- Assess nasal and oral mucosa for redness or irritation
- Place patient in semi fowlers or side lying - reposition every 2 hours
- Monitor cuff pressure: 20-25mm to minimalize risk of necrosis
- Oral care every 4 hours using antibacterial solution and use bite block to avoid biting down on tube
- Communicate frequently with patient and give them means to communicate with like a white board
Metal Trach Tube
Temp sensitive, must be protected from heat and cold to prevent tissue injury
Double Cannula
- Contains outer and inner cannula
- Permanent inner cannula: take out, clean, put back in
- Disposable inner cannula: can dispose and get new one
Parts of Trach Tube
- Outer cannula: outer tube that holds trach open
- Obturator: inserted into the main body of the tracheostomy tube and acts as a guide to help place the trach tube into the airway
- Inner cannula: held in place by twist lock or pressure clip at base of flange
- Flange: Have holes to hold trach in place with tape or Velcro
- Cuff: Balloon around distal end of cannula, forms seal
Cuffed Trach Tubes
- Decreases risk of aspiration
- Seal between upper and lower airway
- Necessary for ventilated patients
- Not inflated for purpose of anchoring the trach in throat but used to direct flow of air
- Cannot talk
Uncuffed Trach Tubes
- Minimal/no risk for aspiration
- No foreseeable need for mech vent
- Peds patients
Cuff Considerations
- Deflation: slow, suction first, deflate during peak inspiration, before oral feeding
Fenestrated Trach Tube
- Has an opening in the tube above the cuff, which allows air to enter so that the patient is able to speak with the tube in place
- Opening plugged to force air upwards to larynx
- Outer cannula has openings on posterior wall
- For vent weaning
Trach Care Considerations
- Humidification: Keeps secretions thin and avoid mucus plugs
- Stoma care: Stoma and dressing clean and dry, Pre-cut non-raveling dressing under face plate
- Secure with 2 people
Emergency Equiptment
- Tube dislodgement and decannulation are problems during first 72 hours
- Have obturator, suction, O2, 2 new tubes - one same size and one smaller, bag valve mask
Accidental Decannulation
- Immediately call for assistance and stay with patient
- Replace with new spare tube or use obturator to keep stoma open
- Prepare for vent if resp distress occurs
Suctioning
- PRN procedure, only when needed
- Removed from nose and mouth for patient airway and block gas exchange
- Lost control to swallow like stroke or unconscious
- Frequent suctioning can cause trauma to mucosa and cause hemorrhage and edema
- Oro: clean tech
- Naso, ET, Trach: sterile
- Nasotracheal suctioning can cause hypoxemia, infections in lungs, atelestasis, and cardiac arrest – vasovagal reaction
- Have patient manage own secretions with turning and coughing/deep breathing every 2 hrs after surgery
Closed System Suction Methods
- Use reusable suction catheter in plastic sheath, does not disconnect system
- Patients attached to vent – reduces risk of hypoxia and infection
- Use for 24 hours
- Use PPE - do not need sterile gloves
Open System Suctioning
- Disconnecting the patient from the ventilator and introducing a single‐use suction catheter into the patient’s endotracheal tube.
- Increased risk for hypoxia because not providing oxygen – sucking it out
- Can stim Vagus nerve - HR could drop
- Sterile cath for every suction session
- Use sterile gloves
Suctioning Pre-Assessment
- Baseline
- Look for signs of hypoxia: restlessness, adventitious breath sounds, decreased O2 sat, tachypnea/cardia
- Effectiveness of coughing
- History of deviated septum, nasal polyps, epistaxis, nasal injury, or swelling
- Need for meds prior
Suctioning Guidelines
- Pre and post assessment after each suction
- Test suction prior
- Hyperoxygenate them with deep breaths or supplemental
- 3 passes only, 10-15 sec per pass, 30 sec-1 min b/w passess
- Suction at 100-125mmHg
Lavage
- Cleaning and removing stomach contents
- Used in drug overdose
- Activated charcoal to absorb poisons, limits toxins entering the bloodstream; alcohol, iron, lithium, metals – not very well absorbed – need an anecdote or polyethylene solution
- Contra: injesting poison, hydrocarbon, corrosive substances or someone has absent protective airway reflexes
- Therapy for hyper or hypothermia to stabilize body temperature
Decompression
- Removes gas and fluids
- Tube connected to suction and removes stomach contents
- Remains in place until normal bowel movements resume
- Indications: rest GI tract from severe V and D, bowel obstruction, paralytic ileus, surgery on stomach or intestine OR clear GI tract - promote healing and allow peristalsis to resume
- Patient is NPO, oral meds can be given but suction must be turned off until absorbed
Compression
- An emergency procedure used to stop bleeding from the upper digestive tract
NG Tubes
- Long, thin, polyurethane, silicon tube, many holes at the end of tube
- Inserted in nasally or orally to administer or remove substances from stomach
- Sizes 4-18 French, broken down by age group
Single Lumen - Levin
- 14-18 French and 125 cm long
- Used for stomach decompression, withdrawing specimens, washing the stomach free of toxic substances, and irrigating stomach and treat upper GI bleeds
- Connected to low-intermittent suction, could cause erosion or tearing of stomach lining if any higher
- Can be used to administer meds or feedings
Double Lumen - Salem Sump
- Most common, 14-18 Fr
- Used for irrigation and tube feeding, preferred for gastric decompression
- Can be used for continuous suction since it is double lumen tube
- Blue vent is always open to air for continuous atmospheric irrigation
- Prevent reflux by having blue vent port above patient’s waist
- Lumens have openings at both ends for air flow
- Irrigating large lumen – inject 20mL of air into blue vent to reestablish buffer of air between gastric contents and vent
- Never clamp off air vent or connect to suction or irrigation
Dobhoff Tube
- Used for enteral nutrition or med administration
- Inserted using guide wire
- Go into jejunum or duodenal areas
Tubes for Upper GI Bleeding for Varices – Sengstaken-Blakemore
- Two lumens inflate gastric and esophageal balloons: one inflates in stomach, one inflates as tamponade to reduce gastoint hemorrhage
- 3rd lumen reserved for gastric suction or drainage
- Can be inserted orally or nasally
- Compresses esophageal varices or reduce gastrointestinal hemorrhage
- ET intubation is strongly advised to secure intubation before insertion
- Only for emergencies
NG Suction
- Prepare for gastric decompression – have suction device in and collection container
- Use lowest suction setting possible, check suction gauges every 2-4 hrs to make sure GI contents are being suctioned up
- Pigtail must be above level of stomach - pin to patient’s gown
- Intermittent suction: Provides alternating periods of gastric tube suction force followed by release, reduces risk of mucosal erosion; in Salem Sump and Levin
- Continous suction: only in Salem sump tube – with air vent that prevents excessive neg pressure from dev in stomach, double lumen
Inserting NG Tube
- Pre-Assessment: inspect nares and patency, have pt occlude one nostril and breathe to see which one is best, test gag reflex, have suction available incase of vom
- Measuring tip of nose to tip of the ear down to xiphoid process
- Can use topical anesthetic or use lubricant
- Position into high-fowlers
- Encourage deep breathing through their mouth
- Advance tube towards posterior pharynx, go up first a little bit, have them tilt head forward and drink water slowly
- Secure with tape
- Experiences resp distress, cannot speak – stop tube and withdraw
Caring for NG Tubes
- Proper placement: aspirate and test pH - 3-5 in stomach, x-ray, air insertion with ausc (really for babies), CO2 detector
- Assess I&O every 8 hrs: lose too much - FVD, report excessive output
- Assess abdomen and gastric output
- Assess adequacy of suction pressure
- Secured on patient’s gown
- Oral hygiene
- Maintain tube patency with intermittent irrigation
NG Irrigation
- Every 4 hours
- Before: ensure placement, check aspiration, measure amount of irrigate in 60mL syringe and instill 20-30mL
- Disconnect proximal end of NG tube from distal end of the suction and slowly instill irrigate into tube
- Irrigate air vent with 20mL of air afterwards
- Document amount of irrigate in intake to subtract from the output
Documentation of Placement
- Type and size of tube
- Nare used
- Stomach contents: characteristics and pH
- Care done
- Patient response
- Teaching that was done
Removing NG Tube
- Try to do trial run with intermittent clamping
- Placement, flushing, positioning
- Tissues and emesis basin
- Inject with 10mL of air before
- Take deep breath in and hold it – closes glottis and reduces risk of aspiration
- Pinch tube at nares and withdraw slowly , do not force
Documentation of Removal
- Condition of nare skin
- I and O
- Tolerance of procedure
- Teaching: Abdominal pain, N or V, Bloating
Ostomies
- Process whereby an opening is created in the abdominal wall for elimination of feces or urine
- Stoma: visible part of temporary or permanent opening created in the abdominal wall during surgical procedure
- 3 Types: colostomy, ileostomy, urostomy
Reasons for Stomas
- Carcinoma – bowel and bladder
- Diverticulitis
- IBD – Crohn’s, UC
- Familial polyposis
- Trauma – gun shots, stabbings
- Neurological damage – MS
- Congenital disorders
Stoma Creation
- Location dependent on waistline, skin folds, scars, type of ostomy performed
- Should look shiny, wet, and red
- Can be protruding, with the skin, or retracted
Colostomy
- Portion of diseased large intestine is removed or bypassed
- Remaining portion is brought through abdominal wall to form stoma
- May be temporary or permanent
- Effluent from colostomies is thicker and more formed the further down the large intestine the stoma is placed
End Colostomy
Damaged section of bowel is removed and working end is brought through the abdomen to skin surface – usually permanent
Loop Colostomy
Loop of bowel is brought to the abdomen to the skin surface and supported by plastic ridge rod, transverse: relieve perforation or obstruction, wall with proximal and distal bowel, two openings to the one stoma
* Proximal end drains stool, distal drains mucus
* Bridge can be removed in 7-10 days
Double Barrel Colostomy
Two separate stomas, two ends of bowel
* Distal colon not removed but bypassed, expels mucus
* Proximal: diverts feces to abdominal wall
Placements of Colostomies
- Ascending colon: to the right, liquid/semi liquid, very irritating to skin
- Transverse colon: top left/middle, usually for temporary ostomies, stoma usually loop, liquid/semi formed
- Descending colon: top left, semi-formed
- Sigmoid Colon: lower left, permanent - cancer of rectum, formed output
Ileostomy
- Created from terminal ileum and stoma is usually on right side of the abdomen
- Bypasses entire large intestine
- Usually done to treat colon cancer, UC, surgical removal of colon
- Stoma has smaller diameter than colostomies
- Effluent from ileostomies is usually very thin and watery at first
- Provide extra care to the skin
- Output: 1-2L per day - dehydration, need skin barriers, Dark green, loose, odorless, then thickens up from yellow to brown, empty when half or third full
- Loose residue diet, avoid high fiber or corn, popcorn, nuts (hard to digest)
Food Blockage in Ileostomies
- Abdominal cramping, N/V
- Swelling of stoma
- Note output for 6 hrs
- Put warm towels on abdomen, drink tea, assume knee-chest position, massage area
- May need to replace pouch with bigger opening if stoma gets bigger
Incontinent Diversion
- Stoma and external appliance to collect drainage
- Entire bladder removed: put in ileal conduit
- Small piece of terminal end of small intestine (ilium) to create drainage port from both ureters that are surgically attached
- Piece of intestine is separated from rest of intestine
- Still has blood supply
- One end is surgically closed
- Ureterostomy: Both ureters are brought to abdominal wall, two stomas
- Transureterouterostomy: one ureter connected to other, one stoma, more complications
Stoma Management
- Assess: color (no dusky/brown/black/pale), moisture, size
- Skin around: keep dry for adhesive to reduce risk of yeast infection, use mild soap when cleaning
- Monitor peristalsis, mucous shreds in urine, I&O
- Measure stoma weekly 8 weeks after surgery
- Contact provider if having stool changes, breakdown of skin, skin irritation, not getting a good seal, see hernia, narrowing, separation of stoma from abdomen, cuts in stoma
Ostomy Pouch
- May be disposable or reusable, one piece or two pieces
- What has best adhesive, best skin protection, stoma location, consistency of drainage, abdominal shape, coordination of patient
- Closed End: one time use, for Sigmoid, have filter for odor
- Open End: multi use for ascending or transverse
- Two Piece: Wafer and then bag clips on for frequent pouch changes, minimizes skin breakdown
Changing Ostomy Bag
- Begin on one corner and slowly pull off
- Can use adhesive removal wipe
- Always do patch test
- Remove if feeling itching and drainage, skin breakdown, rash
- Cut 1/8 inch wider
