Q

what cardiovascular changes occur with positioning from erect to supine?

A

increases — CO, SV, End organ perfusion, venous return

decreases — MAP, HR, SVR (systemic vascular resistance)

Q

what are logistic concerns of prone position?

A

risks are

accidental extubation,

loss of vascular access lines, catheters, & monitors;

& accentuation of multiple trauma.

Q

How should the trunk of the body be supported in prone position?

A

The chest is supported on long cushions or on a longitudinal support frame, allowing as much diaphragmatic & abdominal movement with ventilation as possible

Q

How are the legs positioned in lateral decubitus position?

A

bottom leg flexed

top leg straight

pillow between

17
Q

what is used to prevent brachial plexus injury and ensure perfusion of decubitus side when in the lateral decubitus position?

A

axillary roll

18
Q

What is the position in which the patient is on their back with the hips extened 90o & knees flexed & the thighs apart

19
Q

True or False. When positioning for lithotomy position the patient’s legs should be put into the stirrups one at atime.

A

False. shoud place then simultaneously

20
Q

What are complications of lithotomy position?

A

increase pressure in abdomen and thoraci areas

lower limb nerve injuries (sciatic and common fibular (peronal)

….

21
Q

what is purpose of trendelenburg position?

A

increase venous return during hypotension

improve exposure during abdominal and laproscopic surgery

prevent air emboli & facilitate cannulation during central line placement

22
Q

what are cardiovascular effects of trendelenburg position?

A

Increases CVP

Increases ICP

Increases IOP

Swelling of face, conjunctiva, trachea, and tongue (prolonged head down)

23
Q

what are pulmonary effects of trendelenburg?

A

decrease FRC

decrease compliance

increase work of breathing (spont. breathing)

increase intrathoracic pressure (harder to ventilate)

24
Q

what are some cautions of using reverse trendelenburg (head up)?

A

possible to slide off the table

decrease venous return (hypotension)

more frequent arterial pressure readings to ensure perfusion of brain (level of circle of willis)

25
what are common nerve injuries related to positioning
1 ulnar nerver injury brachial plexus injury radial nerve injury common peroneal nerve injury
26
most nerve injury is caused by what?
Excessive pressure: compression stretch ischemia
27
What is Slight or partial paralysis called?
paresis
28
what is Loss or impairment of the ability to move a body part, usually as a result of damage to its nerve supply
paralysis
29
what is abnormal sensation, typically tingling or pricking (“pins and needles”),
paresthesia
30
what is usually temporary failure of nerve conduction due to injury
neurapraxia
31
At what anatomic location is the ulnar nerve most often injured?
at the medial epicondyle of the humerus near the olecranon process (elbow)
32
Describe arm positioning employed to minimize ulnar nerve injury.
supinated neutral (with thump up when tucked) pad the elbows
33
List three possible causes of brachial plexus injury
abducted more than 90 when supine (stretch) compression in the lateral ducubitus position
34
For a supine patient, what role does head position play in potential brachial plexus injury? What type of injury?
avoid head rotation away from abducted arm (stretch)
