Equipping The OR

Equipping The OR

By Arlene Maloney

This article provides a step-by-step process for choosing and placing OR equipment. Just as Van Gogh begins with a large, white canvas and Beethoven looks at an empty music sheet, operating room service managers start with a vacant operating room to begin their creation. Before the actual equipping of an operating room suite takes place, much preparation is done prior to the floors, ceiling, and walls being in place. Structural engineers calculate the strength of the overhead beams to make sure the OR lights have adequate support. Electrical engineers consider the power needs and emergency power to run all the power equipment. In today's environment, this emergency power is more important than ever--video towers, OR beds, electric cautery units, anesthesia machines, lasers, computers, and the list goes on of the equipment requiring electricity.

One can easily find themselves in a position of not having enough power left in an OR suite to run a certain piece of equipment (i.e., laser) after a new purchase is made if this is not taken into consideration in the onset of the construction.

First the walls are done with the needed electrical lines, telephone lines, water pipes, and computer lines arranged behind the wallboard. The ceiling is completed with structural beams in place under the ceiling tile and overhead, and in-room lighting is illuminating the room where one sees the new floor tile in place. Surely, it is time to begin equipping the OR.

It is difficult to suggest which piece of equipment goes in first. The sterilizer, the operating room lights, or the anesthesia gas column. It doesn't matter, but this is the first phase. If your hospital has a Group Purchasing Organization (GPO), it eliminates the need to evaluate all the vendors for this equipment. It is time consuming and costly to mount OR lights or install an autoclave, and it is also difficult to schedule an installation when you are running a heavy OR schedule. Nonetheless, evaluations need to be done, and if one is lucky, one or two vendors have been awarded contracts, and the process becomes more streamlined for doing evaluations. The anesthesia column probably would not be a piece of equipment that would be evaluated since many inspections and certifications must be met before this equipment can be used. Therefore, the anesthesia column is hung and provides 02, nitrogen, vacuum, and air, nitrous oxide to the OR suite.

Then come the OR lights, seemingly an easy project to do. However, OR lights come in many configurations. One large headlight at the head of the room with two smaller lights at the rear is an option. If one has dedicated OR suites (i.e., neuro surgery or open heart surgery), this configuration may change. If one does not properly plan for the type of surgery being performed, one may find themselves with physician dismay of not having adequate light for their procedures.

The final piece of equipment in phase one installation would be the sterilizer. This too, would have been evaluated and would have to meet required sterilization parameters before any surgery is performed. Oftentimes, one autoclave is installed in a subroom between two OR suites. Good Samaritan Regional Medical Center (Phoenix, Ariz) has an autoclave in each OR. This may sound extravagant, but this OR has a circular design and no subrooms could be constructed.

Phase two begins with the advent of an OR table, anesthesia machine, and monitor. Again, an OR table purchase seems like a simple task. This too, may cause physician disgruntledness. For instance, permanently floor mounted OR tables meet specific surgical requirements if they are working properly. If the table fails, this puts an OR suite out of service until the repairs are completed. Also, more intensive surgical procedures are requiring more radical patient positioning. Therefore, manual OR tables are not being purchased readily. Electrical OR tables are the choice table for surgeons, anesthesiologists, and OR personnel.

Another consideration for an OR table is the ability for image intensification (x-ray). An OR table with a sliding, longitudinal top makes the environment right for laparoscopy procedures. With minimally invasive surgery and laparoscopic procedures becoming the standard and not open procedures, the importance of having the correct features on an OR table is coming to the forefront.

A sensitive subject concerning an OR table is weight capacity. Frequently, nurses phone the OR service manager asking how much weight a table will bear. Unfortunately, the weight of the US population is increasing, and, therefore, the OR table needs to meet that demand. OR tables may hold 350 pounds, 500 pounds, or 850 pounds depending on vendor, make, or model. With patients coming to the operating room weighing over 600 pounds, this is a major concern that the OR table will meet the needs of the surgeon or anesthesiologist to raise, tilt, or put the patient in a trendelenburg position.

The second element of phase two is the anesthesia machine. Much discussion goes on here from the anesthesiologists. Ventilating, drug delivery, and gas delivery to the patient are important aspects of an anesthesia machine. This equipment needs to be evaluated by these physicians, and it is imperative to have written criteria for them to rate this equipment. The time from evaluation to implementation may be a lengthy period so having written documentation will prevent headaches in the end.

The item needing evaluation for the final element of phase two is the anestheisa monitor. Blood pressure, heart rate, EKG, and EEG are all clinical requirements needing to be monitored by the anesthesiologist. This equipment may take months before final implementation; therefore, written evaluation forms would be necessary here. It is not uncommon to have a 12-14 week delivery schedule after a purchase order has been given. Taken into account that the evaluation had been done 6-8 months prior to the purchase, written evaluation forms will refresh everyone's memory on the standards and criteria upon which they had agreed.

With the large pieces of equipment (and the most costly) already installed in the OR suite, now the stainless steel purchases must be made. Ring stands, back tables, mayo stands, kick buckets, prep tables, IV poles, step stools, and case lockers are all necessary to complete an OR suite. Some of this equipment is obvious in its use. IV poles hang IV fluids, and kick buckets house bloody sponges. A ring stand houses a basin for irrigation. Mayo stands and back tables house instruments, sutures, needles, blades, and other sterile material to the operative field. Step stools or stands allow the OR personnel (technician or RN) to stand at the same height as the surgeon and to pass instruments or any piece of material to facilitate the operation. The case locker houses the OR pack, drapes, dressings, etc. according to the procedure being performed and to the doctor's preference items, i.e. silicone versus PVC drain, type of suture needed to close the incision, what dressing is requested, and what gloves are needed. The back tables are first stacked with the instrument trays, power equipment, or telescopes before the surgery begins. When the surgery case is "opened" in the OR suite, the back table and mayo stand are covered with sterile drapes and towels. Quite quickly, this stainless steel phase has added color rapidly with the draping material having many green or blue hues. We are well on the way to completing a masterpiece OR suite.

Finally, the finishing touches are added. In this finale, anesthesia chairs and stools are purchased. In days gone by, this furniture could only be found in black. Now, there are choices of colors and certainly the color helps offset a stark environment. Also at this stage, some hospital environments are allowing border prints if they are washable. A homier, healing environment helps the patient as well as the staff to feel relaxed and have a better mental attitude. The masterpiece is not quite done. Certainly the basic core equipment has been addressed. Now all the specialty implements come forward. Warming units are needed both for the patient and for fluids. Microscopes are needed and often times cannot be configured for more than one specialty. Neuro, ENT, eyes, and hand microscopes are the typical specialties requiring different optics and observor arms. Lasers are purchased or rented according to specialty, also. Holmium lasers, YAG, diode, or CO2 lasers all have different wave lengths and mediums to meet the specific tissue, tumor, or stone removal needs.

Fiber optic headlights and light sources are needed by the surgeon to help illuminate the cavity or portal that has been made. (Halogen light sources are quickly becoming the top choice due to their brighter light.) Light sources are also needed for illumination of telescopes. Arthroscopes, sinus scopes, laparoscopes, cystoscopes, flexible laryngoscopes, and ureteroscopes are just a few of the different ranges of optical instruments required in today's environment. The telescope is used in conjunction with a light cable that is then plugged into the light source.

More often than not, video equipment is required with all the aforementioned telescopes. Video equipment entails a camera, monitor, and usually a VCR and video printer. The camera takes the image from the telescope and projects it to the TV monitor. It is a spectacular view to see an operation being performed on the monitor. Still pictures or a video tape can be recorded if this equipment is available at the time. General OR tables were mentioned previously. However, specialty tables are needed, and it is a challenge to schedule procedures when one considers a fractured hip requires an orthographic table or that a back procedure may need a Jackson or Andrew's table or that a portable cystoscopy table may be required during a gynecological surgery. The other challenge for these OR tables is storage since the tables are not needed for every surgery.

Positioning aids are also a must. Gel rolls or pads help prevent decubitus ulcers. This is extremely important on lengthy procedures. Bean bags, sand bags, and specifically named positions (Montreal or Stahlberg) secure the patient to the OR table while allowing for freedom of movement for the operative site.

In the neuro area, various headrests and skull clamps are required for positioning the patient. Again, the patient must be positioned securely before an operation begins. Finally, the last equipment needed is the instrumentation. This phase never ends. New techniques warrant new instrumentation. Various retractors, specialty power equipment, and general instrumentation needs are an every day juggling act in an OR. One plans for the needs of the day before emergency procedures are added or before the surgeon finds something totally unexpected when an incision is made. Instrumentation is the basic staple of an OR and all the specialty equipment is added after the general instrumentation has been pulled.

Now, this OR is equipped. Van Gogh nor Beethoven might not be impressed by this masterpiece, but any OR personnel would be.
