Q

how to assess for subcut emphysema

A

inspect and palpate skin around insertion site and along arm. this may reveal edema where air is located, and air may travel if skin is loose. palpation reveals a crackling sensation such as popping plastic bubble wrap

Q

interventions pneumothorax, hemothorax, air emboli, hydrothorax
ssessment

what to do if air emboli is suspected

A
  • give 02 as nec
  • elevate feet
  • aspirate air, fluid
  • if air emboli is suspected, PLACE PT ON LEFT SIDE WITH HEAD DOWN. remove catheter as ordered
  • help w insertion of chest tube
26
Q

incorrect placement assess

A 
-cardiac dysrhythmias
HoTN
neck distension
narrow pulse pressure
retrograde flow of blood (fow of blood back into tubing usually cused by decreased pressure gradient between venous system and access device unit eg IV infusion, heparin lock)
27
Q

incorrect placement prevention

A
  • obtain xray film xm after placement

- reposition catheter as warranted

28
Q

incorrect placement intervention

A

stop all fluid admin until placement is confirmed

  • d/c catheter
  • xray and ECG for CVADS and PICCS. admin support meds as nec
29
Q

Infiltration

definition

A

Infiltration

• The unintentiojnal admin of a nonvesicant soln or med into surrounding tissue

30
Q

med surgs suggestion of how infiltration might present

A

• characterized by edema around insertion site
o discomfort
o coolness
o significant dec in rate

31
Q

how is infiltration usually easiy recog

A

• usually recog by bilateral comparison (look for swelling)

32
Q

does backflow of blood into tubing prove anything

A

nope. doesnt means its still in vein

33
Q

what is more reliable than backflow of blood fr det if peri0ph IV is in vein

A

• it is more reliable (than testing for backflow of blood) to put a tourniquet above infusion site and tighten it enough to restrict venous flow. If continues to drip despite obstruction of venous return then infiltration is present

34
Q

what do if infiltration is suspected

A

• if infiltration is detected, the infusion should be stopped, IV d/c, sterile drsg applied to site after careful inspection to det the extent of infiltration

35
Q

infiltration scale

A
  • 0=no symptoms
  • 1=skin blanched, edema less than 1 inch in any direction, cool to touch, with or without pain
  • 2=skin blanched, edema 1-6 inches in any direction, cool to touch, with or without pain
  • 3=skin blanched, translucent, gross edema greater than 6 inches in any direction, cool to touc, mild to moderate pain, possible numbness
  • 4=skin blanched, translucent, skin tight, leaking, skin discoloured bruised, swollen, gross edema greater than 6 inches in any direction, deep pitting tissue edema, circ impairment, moderate to severe pain, infiltration of any amount of blood products, irritant, or vesicant
36
Q

not sure if useful as our coursepack may contradict but when to use hot and cold for infiltration

A
  • may apply warm compress to site if small volumes of noncaustic soln have infiltrated over long period or if the soln was isotonic w normal ph
  • if infiltration was recent and soln was hypertonic or had inc ph, can apply cold compress to area
37
Q

can you use same arm as there was infiltration for IV

A

yes but it must be proximal and in new site

38
Q

extravasation is

A

• similar to infiltration w inadvertent admin of vesicant or med into surrounding tissue that can cause blistering, inflm, necrosis of tissue

39
Q

extravasation how do you determine the extent of damage

A

• extent of amage determined by conc of med, quanitity that extravasated, the location of the infusion site, the tissue response, and the duration of the process of extravasation

40
Q

extravasation interventions

A

• stop the infusion and notify dr, dr often says to give antidote, remove the cannula an apply warm compress to site

41
Q

can you use same arm for IV after extravasation

A

no

42
Q

what type of assessments to do after extravasation

A

thorough neurovascular assessments

43
Q

extravasation on the phlebitis scale

A

• extravasation is rated as 4 on phlebitis scale

44
Q

diff kinds of phlebitis

A

• can be chemical, mechanical, bacterial but often two or more occur at once

45
Q

would a fast infusion rate result in chemical or mechanical phlebitis

A

chemical

46
Q

phlebitis scale

A

• phlebitis scale
 0-no symptoms
 1-erythema at access site w or wout pain
 2pain at access site w erythema and or edema
 3-pain at access site w erythema and or edema. Streak formation. Venous cord.
 4-pain at access site w erythema and or edema. Streak formation. Palpable venous cord >1 inch in length. Purulent drainage.

47
Q

phlebitis tx

A

d/c the line
restart in another site
apply warm, moist compress to affected site

48
Q

thrombophlebitis is

A

• The presence of a clot and inflm of the vein

49
Q

s/s of thrombophlebitis

A

s local pain, rdness, warmth, swelling around insertion site or the path of the vein, immobility of the extremity d/t discomfort an swelling, sluggish flow rate, fever, malaise, leukocytosis

50
Q

tx of thrombophlebitis

A

• tx: d/c IV old compress to dec blood flow and inc platelet aggregation and the a warm compress; elevate the extremity and restart the line in opposite extremity

51
Q

thrombophlebitis has mnfts

A

if pt has s/s of thrombophlebitis don’t flush

52
Q

should you flush pt IV if they have thrombophlebitis

A

• culture the catheter after cleaning the skin around the catheter with alcohol

53
Q

thrombophlebitis prevention

A

• can be prevented with avoiding trauma to the vein at the time the line is inserted, observing site q1h, checking med additives for compatability

54
Q

extravasation prevention

A

• prevention: monitor often, don’t insert in area of flexion, secure, use smallest cathteter possible

55
Q

what can cause hematoma

A

• can happen when the opposite vein wall is punctured, needle slips out of vein, insufficient P is applied to the site after removal of the needle or cannula

56
Q

s/s hematoma

A

• s/s=eccymosis, immed swelling at site, leak of blood

57
Q

tx of heamtoma

A

• tx: removing the needle or cannula and applying light pressure w sterile, dry drsg; apply ice for 24hrs to avoid extension; elevating the extremity; assessing the extremity for any circulatory, neuro, motor dysfx and restart the line in other limb if nec

58
Q

when does clotiing or obstr occur in periph IV

A

• may form d/t kinked line, slow rate, empty IV bag, fail to flush the line after intermittent med or soln admin

59
Q

what to do and not do if clot in line

A

• if clot occurs d/c and start in new site. don’t irrigate or milk tubing don’t raise infusion rate or soln container and don’t aspirate the clot

60
Q

prevention of clot in periph IV

A

• prevention: don’t let bag run dry, taping in tubing to prevent kinking and maint patency, maint adequate flow rate, flush line after intermittent med admin or soln admin
