Perioperative Setting

Presented by

ALLEN LEUNG, RN, PYNEH

Objective

• The goals of the operative positioning

• Anatomic consideration for positioning

• Guidelines for safe positioning

• Various kind of positioning device

• Common positions for operation

Goals

• Provide optimum exposure and access to the

surgical site.

• Provide access for the administration of the

anaesthesia and patient’s monitioring.

• Maintain patient normal phsiological function

including breathing and circulation.

• Prevent patient from injuries and post- operative

discomfort.

Anatomic consideration for positioning

• Respiratory Consideration ▫ Hindered diaphragmatic and chest movement

• Circulatory Consideration ▫ Thrombus formation

▫ Occlusion of peripheral blood vessels

• Peripheral Nerve Consideration ▫ Common sites: brachial plexus, ulnar and radial nerves

▫ Prolonged pressure on or stretching

• Musculoskeletal Consideration ▫ Strain of muscle and hyperextend of the joint

• Soft tissue Consideration ▫ Skin pressure ulcers and deep tissue injury over bone

prominences

Pressure ulcer

• Pressure over 32mmHg reduces capillary flow predisposes the patient to pressure injury

This pictorial shows the pressure map of a 185 lb male resting on a foam OR table mattress while in the supine position

Pressure ulcer Guidelines for safe positioning

• Prepare operation table accessories and lock it securely before

positioning

• Move the patient only after the anaesthesia care team gives approval

• Guard and support the patient’s head at all times by the anaesthesia care

team during movement

• Move the patient slowly and gently

• Provide adequate numbers of personnel for the safe movement of the

patient

• Prevent hyperextension of arm (90-degree) and legs crossed

• Watch out for endotracheal tubes, IV lines, drains, urinary catheter and

etc to prevent kinking and pulling them out

• Prevent the patient to touch any exposed table parts or hang over sides

Positioning Device – operating Table

Characteristics:

•Stable

•Easily maneuverable

•Highly adjustable

•Adaptable

•Comfortable

•Radiolucent

Operating Table Accessories

Body (Hip) Restraint strap

• Place the strap over the patient’s hips to secure the patient in the lateral position

Anaesthesia Screen

• Hold the drapes from the patient’s face/IV access

• Separate the nonsterile from sterile area

Armboards • Support the arms

Operating Table Accessories

Headrest

• Hold the head securely

Skull clamp • Three-point fixing the patient’s head for neurosurgery or cervical spine operation

Operating Table Accessories

Shoulder Braces • support the shoulders to prevent the patient

from slipping, such as in the Tendelenburg’s position

Side and Lumbar supports

• Support lumbar vertebral in lateral position

Foot Support • Support the feet in reverse Trendelenburg’s position

Stirrups

• Support the legs and feet in the lithotomy position

Operating Table Accessories

Adjustable Arched Spinal Frame • Adjust the spinal frame arch for spinal surgery

Gas spring

assisted stirrups

Knee crutches

Candy cane or

sling stirrups

Perineal Post

• Prevent injury during traction against the perineal region

Traction Boot

• Secure a leg to a traction boot for applying the traction

Operating Table Accessories

Head table • Support the operative arm

Different types of padding / postioner Supine Position

Supine Position

• Patient on back with face toward ceiling

• Legs uncrossed

• Position arms at sides or on armboards, turn the palms towards the patient or turn the palms up

• Prevent to hyperextend both arms more than 90o

• Place safety belts 2” above the knees and both arms, and not so tight as to impeded circulation

• Place paddings under head and heels

• Place a small pillow under calves supporting the full length of the lower legs

• Apply anti-embolism stockings if necessary

• For the pregnant patient, a wedge should be placed under patient’s right side to shift the uterus to the left and relieve compression on the aorta and vena cava

Supine Position

Use for : • Administration of general anesthesia • Anterior Chest surgery e.g. Open heart surgery • Surgery on face, neck, or mouth • Most surgery on extremities Vulnerable Anatomy: • Occiput, Scapulae, Olecranon (elbows) , Thoracic Vertebrae, Lumbar area,

Sacrum & Coccyx, Calcaneus (Heels)

Potential Injuries: •Lumbar strains •Nerve injury: Brachial plexus Radial nerve Ulnar nerve •Skin damage

Supine Position

Trendelenburg Position

Use for:

• Lower abdominal surgery

• Insertion of central catheter

Reverse Trendelenburg Position

Use for:

• Face and Neck surgery

Lateral Position

Lateral Position • Patient begins in supine position • Turn shoulders and hips simultanously – operative side up • Place their back on the edge of the operation table • Maintain spinal alignment • Flex lower leg at knee and hip, keep upper leg straight or

slight flexed • Place pillow to separate two legs • Place and secure lower arm on an armboard, and upper arm

on an overbed arm support/gutter or pillow with elbow slightly flexed and upward, but not more than 90-degree

• Place paddings under head, ankle, knee, hip and axilla • Place safety belt across hips, and pelvic and sacral supports to

hold the patient in position • Place the short kidney rest against the back, & a large kidney

rest against the abdominal wall with padding • Place lower margin of rib cage just level with the break point

Lateral Position

Potential injuries: Nerve injury: Brachial plexus Radial nerve Ulnar nerve Peroneal nerve Use for : •Kidney surgery •Hips surgery •Thoracic surgery • Feet

Vulnerable Anatomy: • Dependent side of face and ear • Dependent shoulder • Arms • Dependent axilla • Dependent hip • Legs • Dependent knee • Ankles

Lithotomy Position Lithotomy Position

• Patient begins in supine position

• Lift both legs with knees together simultaneously into stirrups or leg holders

• Avoid forcing the legs

• Avoid hyperflexion of the hips

• Place arms on armboards or over chest

• Do not extend patient’s buttock over the break in the operation table

• Place paddings under head and stirrups

• Lower both legs slowly and simultaneously

Role of the Perioperative Nurse

• Patient Advocate

• Patient Assessment:

▫ History, Pre- existing condition, expected surgical procedure

• Planning Care:

▫ Required equipment and setting

▫ Number of person needed

• Implementation:

▫ Transportation > Transfer > Positioning > Transfer

▫ DIGNITY of patient

• Evaluation:

▫ Thorough, once- over check

• Documentation
