periop/postop Flashcards
second mc complication in surgery
nerve damage due to positioning
5 P’s of writing orders
pain (mild to severe controlled w meds or position)
pee (urination)- urinary cath q6prn; indwelling cats can lead to infx and may lead to oliguria after removal bc pt has been relying on cath
poop (BM)- constipation can cause urinary problems
puking (nausea)
pyrexia (fever)
what should there be evidence of prior to feeding following abd operations
evidence of peristalsis- bowel sounds, passing gas
what is POD1
first day after an operation
tmax
max temp w/in last 24hr
tachycardia, metabolic acidosis, hyperthermia, hypercapnia
malignant hyperthermia (postop anesthesia problem)
102.5
tx of malignant hyperthermia
IV dantrolene
goal of surgical drains
dec infx rate and dec healing time
indications for surgical drains
eliminate dead space; evacuate accum of gas, bile, pus, blood, or fluid; prevent accumulation of gas, bile, pus, blood, or fluid
penrose (passive drain)
latex and dependent on capillary action; drainage is related to surface area
adv of penrose drain
allow drainage, help obliterate dead space, soft/malleable (less painful)
disadv of penrose drain
very irritating, allow bacterial ingress, can’t be connected to suction, gravity dependent
jackson pratt (active drain)
soft w multiple perforations; bulb that can recreate low neg pressure vacuum; designed so tissues are not sucked into tube
hemovac (active drain)
needle for placement (needs to be cut out in order for suction to work); accordion like reservoir (evacuator); more volume capacity than JP; placed away from incision so wound can heal
adv of active drain
keep wound dry (efficient fluid removal), can be placed anywhere, prevent bacterial ascension, help appose skin to wound bed (quicker wound healing)
disadv of active drain
high negative pressure may injure tissue; drain clogged by tissue
why are there complications and failures of drains
poor drain selection, poor drain placement, poor post op management
breakdown of anastomotic site; erosion into hollow organs; incisional dehiscence/hernia (poor placement); premature removal (accum of fluid); dec mobility (DVT/PE, inc hospital stay)
which drain is more likely to be assoc w an infx
pinrose- ascending bacterial invasion; foreign body reaction; dec local tissue resistance; bacterial hiding places; poor placement (fluid accum, drain kinked), poor postop manag
causes of inefficient drainage
exiting in non dependent locale (passive drains); kinked tube; obstructed; poor drain selection (diameter too small to remove viscous fluid)
when should drain be removed
when drainage ceases
obligatory urine output for adult
generally 50ml/hr
the 5 W’s for postop fever
wind (24-48hr, atelectasis); water (3d, UTI); wound (5-7d, infx); walking (7-10d, DVT); wonder drugs
w/u for postop fever (>101.5)
PE (lungs,heart, site, calf tenderness, Homans); cxr; UA; blood cx (2 sep sites); cbc
