The Papanicolaou test, commonly known as a Pap smear, is a screening procedure designed to detect precancerous or cancerous cells on the cervix, the opening to the uterus. This examination requires a medical instrument called a speculum to gently open the vaginal walls, allowing the clinician to visualize the cervix and collect a cell sample. While this procedure is quick and routine, the use of the speculum can be a source of anxiety or discomfort for many people. Understanding the technical steps involved in the insertion process can help demystify the experience and highlight the measures taken to ensure comfort and accuracy.
Preparing for the Examination
Preparation begins with the patient being positioned appropriately, typically in the lithotomy position, where the individual lies on their back with feet supported in stirrups. This positioning helps relax the pelvic muscles and provides the clinician with optimal access to the vaginal canal and cervix. Raising the head of the bed slightly can help the patient relax the abdominal and pelvic muscles, reducing tension.
The clinician chooses the speculum type and size to match the patient’s anatomy, minimizing discomfort while allowing for clear visualization. Speculums are available in narrow, medium, and large sizes, made of metal or disposable plastic. The metal speculum is often warmed before use, since cold metal can cause muscle tension upon contact.
Applying a water-soluble lubricating gel to the outer inferior blade of the speculum is a routine step that eases insertion and reduces patient discomfort. Though traditional practice sometimes recommended using only warm water, modern studies confirm that a small amount of water-based lubricating gel does not compromise the integrity of the collected cell sample. The clinician ensures the patient’s bladder is empty before the procedure, as a full bladder can contribute to discomfort during the examination.
The Physical Insertion Technique
Insertion begins with the clinician using two fingers to gently separate the labia and apply slight downward pressure on the posterior vaginal wall. This action helps to open the vaginal entrance and relax the external muscles. With the speculum blades fully closed, the clinician inserts the instrument carefully, aiming with a gentle, downward tilt toward the patient’s sacrum or lower back.
This downward angle follows the natural curve of the vaginal canal and avoids putting pressure on the anteriorly located urethra. The speculum is inserted about two-thirds of the way into the vagina, maintaining this slight downward pressure to navigate the canal. The speculum is typically oriented with the blades vertically, or sideways, to utilize the widest part of the introitus for entry.
Once past the vaginal entrance, the speculum is rotated 90 degrees so the blades are in a horizontal position and fully inserted until the handle is near the perineum. The blades are then slowly opened, separating the vaginal walls to bring the cervix into view. The clinician opens the blades only as much as necessary for clear visualization, as excessive distension can cause pain.
The cervix is identified, appearing as a smooth, pink, round or oval structure at the end of the vaginal canal. Once the cervix is centered between the opened blades, the clinician locks the speculum into position using the thumbscrew or locking lever. This mechanical lock keeps the blades open, freeing the clinician’s hands to collect the cell sample using a small brush or spatula.
Strategies for Patient Comfort
Communication between the patient and the clinician is essential for a comfortable examination. The clinician should explain each step of the procedure beforehand, alerting the patient to sensations they may experience, such as initial pressure or the sound of the locking mechanism. Patients are encouraged to voice any discomfort immediately, and the clinician should be prepared to stop or modify the procedure.
Patients can actively participate in reducing discomfort through relaxation techniques. Deep, slow abdominal breathing, where the hands placed on the abdomen rise and fall, can help to soften the pelvic floor and reduce muscle tension. Some individuals find that consciously bearing down or gently pushing, similar to a bowel movement, as the speculum is inserted can facilitate relaxation of the muscles surrounding the vaginal opening.
Individuals can advocate for modifications to the standard procedure to suit their needs. Requesting the smallest possible speculum size, such as a pediatric or narrow blade, can be helpful, especially for those with a history of pain or those who have not had a pelvic exam before. In some cases, a patient may request to guide the speculum themselves during the initial insertion, which provides a sense of control over the depth and speed of the process, potentially easing anxiety and allowing the pelvic muscles to relax.
