PORTABLE OR applications and Considerations Week 13 RTEC 124

CAUTION: SOME IMAGES MAY BE DISTURBING BUT AS HEALTHCARE PROFESSIONALS THIS IS WHAT YOU MAY EXPERIENCE

Who are these people?

Importance of maintaining a sterile field…. Your role as an RT

STERILE IN OR Must change clothing Must change clothing Wear a “cover gown” when leaving Wear a “cover gown” when leaving Masks, hair cover, and shoe covers Masks, hair cover, and shoe covers Change when you leave the OR room Change when you leave the OR room DO NOT TAKE HOSP SCRUBS HOME!! DO NOT TAKE HOSP SCRUBS HOME!!

The Operating Room Team…you are part of it!

What to expect…

From your point of view do not touch sterile field

Surgical Radiography Imaging is commonly used in surgical procedures Imaging is commonly used in surgical procedures But the surgeon already has the patient’s body open, right? But the surgeon already has the patient’s body open, right? Sometimes it is used as a guide Sometimes it is used as a guide

Must cover equipment in sterile drapes when it may come into contact with patient, instruments, or surgeons hands Must cover equipment in sterile drapes when it may come into contact with patient, instruments, or surgeons hands

Sterile trays

The sterile incision covered for portable Instruments away from portable Never use portable over sterile field USE CAUTION!

Exchange the IR into the sterile drape

SURGERY Sterile procedures must be followed Sterile procedures must be followed –Not to contaminate surgical site –Don’t touch anything BLUE or GREEN –Be careful not to run into trays, etc

IMAGING IN THE OR Moblie Radiographic Moblie Radiographic Mobile C-arm – fluoroscopic Mobile C-arm – fluoroscopic Dedicated room Dedicated room –Cystography –Radiography room

Equipment in the OR must be covered Equipment in the OR must be covered –Must be cleaned before bringing into room Protects patient Protects patient –Prevents contamination of sterile field and instruments UNLIKE PORTABLE EXAMS ON THE UNITS

Set up room in advance if possible

Fluoroscan

Hand surgery table Never use IR as a table Never use IR as a table –Blood –Fluids –Water

Some tables have a gap Some tables have a gap –Allows for cassette placement without contaminating sterile field

Tables without gap Slide cassette at top with help of anesthesiologist Slide cassette at top with help of anesthesiologist

Considerations before procedure Find out where surgeon wants you to go Find out where surgeon wants you to go Be careful not to contaminate Be careful not to contaminate Plug in C-arm and test it Plug in C-arm and test it –Marker check on II if possible –Guard FOOT Switch Park portable equipment in corner –out of the way Park portable equipment in corner –out of the way

Orient anatomy using markers

Mobile Radiography Considerations If surgery is already in progress If surgery is already in progress –Before entering, park machine outside of room –Survey room to get lay-out –Rearrange equipment/furniture if necessary Place cassette in a STERILE WRAP Place cassette in a STERILE WRAP

PATIENT CONSIDERATIONS DURING SURGERY Patient may not always be “unconscious” Patient may not always be “unconscious” –Pain management –Twilight state Always treat patient with respect and courtesy Always treat patient with respect and courtesy –They may be hearing everything

USING C-ARM vs PORTABLE C-ARM Faster- instant image Faster- instant image More radiation More radiation Smaller field of view Smaller field of viewPortable Must have accurate technique Must have accurate technique Processing needed Processing needed –Longer Larger field of view Larger field of view

Various Imaging Procedure in Operating Room

SURGERY - Common Procedures Ortho (Bone) Work Pinning/ Rod / Screw placement Pinning/ Rod / Screw placement Fracture realignment Fracture realignment Organs / Vessels with contrast Arteries / Veins in the extremities Arteries / Veins in the extremities Cholangiograms = ducts Cholangiograms = ducts Urography Urography Pacemaker and Line Placements etc

TECHNIQUE CONSIDERATIONS Same principles of ALARA Same principles of ALARA Change techniques if using grid Change techniques if using grid –3-5 times more if using grid –Body parts larger than 12cm SID – SID – – VERY IMPORTANT TO MEASURE –Chest usually done at 63-72” –All others done at 40”

USE OF PORTABLE CROSS TABLE LATERAL C.SPINE Lateral projection of the cervical spine with patient supine. Done to verify the correct position of instruments before continuing surgery. Often a spinal needle is placed in the disc space to show position.

Discectomy

Lateral Lumbar Drape C-arm with sterile plastic conver to protect patient and equipment

PA Lumbar AP or PA to lateral AP or PA to lateral –Caution not to hit patient or equipment –KEEP STERILE Familiarize yourself with locks Familiarize yourself with locks –PRACTICE WITH CI, RT’S

RAD PROTECTION in the O.R. It’s your duty to protect the patient, yourself and others (healthcare professional) It’s your duty to protect the patient, yourself and others (healthcare professional) Politely ask whoever can, to move back from the area Politely ask whoever can, to move back from the area Provide aprons to those who cannot leave Provide aprons to those who cannot leave Announce your intent to make an exposure and give time for others to move back Announce your intent to make an exposure and give time for others to move back IF personnel are in sterile drape – may not be able to put on apron IF personnel are in sterile drape – may not be able to put on apron

RAD PROTECTION RULES OF GOOD PRACTICE Never place your hand or other body part in primary beam Never place your hand or other body part in primary beam Provide gonadal protection for the patient if possible Provide gonadal protection for the patient if possible FOR C-ARM – IF BEAM FROM BELOW – PLACE APRON ON TABLE BEFORE PATIENT IS ON TABLE FOR C-ARM – IF BEAM FROM BELOW – PLACE APRON ON TABLE BEFORE PATIENT IS ON TABLE Achieve maximum distance from the patient and tube (stand 90° from the patient) Achieve maximum distance from the patient and tube (stand 90° from the patient) Minimum 6 foot exposure cord for radiography Minimum 6 foot exposure cord for radiography Label and handle cassettes carefully Label and handle cassettes carefully

Portable and Mobile Competencies YOU MUST ALWAYS HAVE SUPERVISION YOU MUST ALWAYS HAVE SUPERVISION EVEN AFTER COMPETENCY IS DONE per JRCERT EVEN AFTER COMPETENCY IS DONE per JRCERT DO NOT PUT YOURSELF IN A SITUATION WHERE YOU DO NOT HAVE APPROIATE SUPERVISION !

OR / PORT COMPS Still need direct supervision- even after you have a competency Still need direct supervision- even after you have a competency Must have “DIRECT” supervision for portables and C-arm at ALL times Must have “DIRECT” supervision for portables and C-arm at ALL times

PORTABLE & C- ARM COMPETENCIES Must do a Pre-Portable check –off first Must do a Pre-Portable check –off first C- Arm check off C- Arm check off Must do more than 3 exams of each area – portable – before attempting competency Must do more than 3 exams of each area – portable – before attempting competency
