Positioning (Exam 2) Flashcards
What is part of standard 8: Patient positioning
- collaborate with team, assess, monitor proper body alignment
- use protective measures to mainain perfusion and protect pressure points and nerve plexus
What effects does supine positioning have on CV/respiratory physiology?
- Increase VR, increase preload, stroke volume and CO
- Decreased Vt and FRC
What complications can occur due to supine positioning
- backache
- pressure alopecia
- brachial plexus or axillary nerve injury if arms abducted >90
- ulnar nerve injury if palms are pronated (facing down)
- stretch injury when neck is simultaneously extended and turned to the side (brachial plexus)
When positioning patient with tucked arms (adduction) palms should face what directions?
Neutral (towards body) or prone
Where is your head during Trendelenburgh
DOWNNNNNN
What positioning devices/considerations should you consider with T-burg?
- Non-sliding mattress
- avoid should braces/bean bags
- Mark patients head position at beginning to help monitor any sliding
Shoulder braces during T-burg pose what risk to the patient?
compression injury of the brachial plexus
How much can cardiac output increase 1 minute into Tburg positioning?
~ 9%
T-burg positioning is contraindicated for what patients?
Patients with increased ICP
What negative post-op complications arise due to t-burg positioning
- post-op vision loss
- edema of face, conjunctiva, larynx, tongue
- increased intrabdominal pressure (aspiration)
- decreased FRC /compliance
- main stem intubation d/t shifting of everything cephalad
- brachial plexus and ulnar nerve injury also possible d/t supine position
Patients with kyphosis, scoliosis, or a hx of back pain may benefit from what positioning inverentions
extra padding/ slight flexion at the hip and knee.
What’s more common ulnar nueropathy or brachial plexus injuries?
Brachial plexus is more common in recent claims data
A patient in reverse T-burg’s head will be above or below the feet
Head ABOVE feet
Safety considerations for reverse trendelenburg
pad feet, foot rest, non-sliding mattress
Pathophysiology of reverse trendelenburg
hypotension, venous pooling, decreased brain perfusion
