By the end of this module, learners will be able to provide effective intraoperative support to the surgeon by performing tasks such as tissue retraction and suctioning. They will understand how to anticipate surgical needs, use instruments appropriately, and contribute to a safe, efficient operative environment.

• Identify common verbal and non-verbal cues surgeons use and explain how anticipation supports operative flow.
• Describe the correct use of suction and irrigation techniques to maintain a clear operative field.
• Recognize common retractors and explain how they are positioned to optimize exposure while minimizing tissue injury.
• Explain the nurse’s ?? (surgical assistabt's role) role in supporting interrupted and continuous suturing, including maintaining proper tension.
• Identify common suture techniques and their appropriate applications.
• Explain how monitoring patient responses, tissue changes, and off-field equipment contributes to safe and efficient surgery.

Anticipating the surgeon’s needs means mapping the operative phases to the surgeon’s hand movements and rhythm, and acting before a request is made. When the surgeon begins clamping a vessel, the scrub nurse should already have a tie or a loaded needle holder positioned on the Mayo stand, ready for immediate handoff. If dissection is underway and visibility narrows, retractors should be rotated in without delay, and suction tips should be positioned at the field edge before bleeding obscures the cavity. During closure, sutures must be grouped and preloaded in the exact order of use—fascia sutures first, then subcutaneous, then skin—so the surgeon never pauses to wait for the next strand. Anticipation is not just stocking the right tool but having it oriented, clean, and immediately accessible in the surgeon’s working hand the moment it is needed.

Communication within the team is achieved through economy of words and precise response to cues. Surgeons rarely verbalize every need; instead, they signal readiness through consistent gestures or short commands. The scrub nurse should act on these signals first, and use short confirmations only when necessary (“Richardson in,” “suction ready”). Examples of common cues include:

Non-verbal cues

• Hand extended, palm up → surgeon ready to receive an instrument.
• Hand rotation with palm up → surgeon preparing to tie; scissors should be readied.
• Index finger pointing into the wound → assistant should place a retractor or suction tip at that spot.
• Brief pause with eyes fixed on a bleeding site → suction tip or hemostat should be positioned immediately.
• Lifting elbow or wrist upward while dissecting → suction is needed to clear the field.
• Shifting scalpel to non-dominant hand → surgeon is ready for scissors or forceps in the dominant hand.
• Spreading two fingers apart in the wound → replace fingers with a retractor.

Verbal cues

• “Suction here” → place suction directly at the indicated site until visualization is restored.
• “Deeper” or “More exposure” → introduce a larger retractor.
• “Ready for tie” or “Tie, please” → provide a preloaded needle holder or ligature.
• “Cut” → scissors should already be in hand to trim the suture.
• “Hold here” → take over tissue traction or stabilization where indicated.

By recognizing and acting on these cues promptly, the scrub nurse reduces unnecessary dialogue, maintains the surgeon’s focus, and ensures the procedure progresses smoothly.

Suction should be prepared in advance with two common tips:

• Yankauer for general clearance
• Frazier (sizes 8–12), a thinner instrument for precise suction in deeper or narrower cavities

Before incision, flush the line with sterile saline to ensure patency, and keep a 10 mL syringe of saline on the Mayo stand to clear clots if occlusion occurs.

The Yankauer should be positioned at the edge of the field, not resting directly on tissue. When used, it is placed at the dependent portion of the wound for three to four seconds at a time, then withdrawn to prevent continuous tissue dehydration.

The Frazier suction tip is held like a pencil, angled between 30–45 degrees, and placed adjacent to but not directly on vessels or nerves. A small sterile gauze can be interposed between the tip and delicate tissue to prevent trauma. During fine dissection, suction is advanced only far enough to clear blood or fluid without obstructing the surgeon’s instrument. After each use, the side hole should be uncovered to release suction and prevent clogging.

Irrigation is prepared in pre-filled syringes labeled “20 mL” for precise flushing and “50 mL” for bulk lavage. Irrigation begins once dissection reaches a cavity or when the surgeon requests to clear char, blood, or debris. The assistant directs irrigation streams along the wound base or cavity wall, never directly at vessels, nerve bundles, or fresh suture lines. Immediately afterward, suction is applied at the dependent edge so fluid drains away from the operative site, leaving tissue moist but not flooded.

The surgical assistant should sequence suction and irrigation in paired actions: apply irrigation, then follow within two seconds with suction. When repeated cycles are needed—for example, after cautery—the assistant alternates smoothly until visualization is restored. If pooling persists, sponges mounted on sponge sticks should be used in combination with suction to absorb and remove residual fluid.

Retractor use progresses with incision depth. After skin entry, two-prong or small skin hooks are used to elevate wound edges. As dissection continues, Army-Navy retractors are introduced on either side, blades downward, to expose subcutaneous tissue. Once fascia is opened, Richardson retractors are placed deeper, with the blade resting against muscle or fascia, never directly on vessels or nerves.

For broad cavity exposure, a Deaver retractor is selected. Its curved blade should be cushioned with a moist lap pad where it rests on bowel, liver, or other viscera. The assistant maintains steady pressure directed opposite the surgeon’s line of dissection. If self-retaining exposure is required, a Weitlaner retractor is opened incrementally, with ratchets engaged only as far as needed to prevent tissue tearing. In large abdominal cases, a Balfour retractor may be assembled with side and center blades, adjusted gradually as the cavity deepens.

The assistant must monitor tissue under retraction every 15–20 minutes. If skin or muscle appears blanched, pressure should be eased or the retractor repositioned. Blades must not slip or ride on nerves; placement should be checked against anatomic landmarks. When retractors are switched, the outgoing instrument is wiped clean of fat or clot before being returned to the stand.

Retractors are always passed handle-first, blade pointing down, directly into the surgeon’s palm. Removed retractors are placed in a defined group on the Mayo stand so the same instrument can be redeployed without confusion. If multiple retractors are in use, the assistant should mentally track which tissues each one supports, so adjustments can be made quickly when exposure needs to change.

A more thorough description of suturing is described in Suturing and Suture Removal - ECSACONM.

During continuous suturing, the assistant’s primary responsibility is to maintain smooth strand control, ensuring consistent tension and a clear operative field as the surgeon works. The strand should advance freely without slack or drag, allowing uninterrupted rhythm. The assistant gently feeds the suture forward with each pass, keeping it straight and untwisted to prevent tangling. Any loops or kinks should be corrected immediately by lifting and straightening the strand.

Tension must remain steady and balanced—firm enough to support tissue approximation but not so tight as to cause blanching or distortion. The assistant anticipates the surgeon’s next move by preloading the following needle holder before the current layer is completed, ensuring seamless workflow between closure steps.

As knots are tied, the assistant maintains gentle counter-tension until the surgeon signals release. For fascia, upward traction helps the knot lay flat in the tissue plane; for skin, lighter tension prevents “railroad track” marks. Once the knot is secured, scissors are passed immediately—tips directed toward the suture—for precise trimming. Absorbable sutures are typically trimmed to 3–5 mm tails, and non-absorbable sutures to 5–7 mm, unless directed otherwise.

When interrupted suturing is used, each stitch is tied individually for secure closure. The assistant maintains steady counter-tension on the free end, angled 30–45 degrees away from the wound edge, ensuring even approximation without crushing or lifting tissue.

All suture materials and sharps must be managed within the sterile field using neutral zone principles. Needles and loaded needle holders are never handed directly but placed safely for retrieval. Used or trailing strands are secured with hemostats and organized on the Mayo stand or sterile instrument tray to maintain a safe, uncluttered field.

The assistant’s responsibility extends beyond the incision itself. Patient responses should be observed continuously: for example, noting pallor of exposed skin, diaphoresis, or a sudden increase in bleeding into suction canisters. These changes should be communicated directly to anesthesia with a short, precise report (“500 mL in suction canister,” “skin color pale”).

Within the operative field, the assistant monitors tissue integrity at retraction sites. Every 15–20 minutes, check for color changes, swelling, or tearing. If the cautery pencil is active, ensure no damp sponges or drapes are touching the tip. Smoke accumulation should be cleared with suction immediately to restore visibility and prevent burns.

Instrument and supply organization outside the wound must also be controlled. Used sponges should be placed directly into the kick bucket or counting system, never left on drapes. Instruments no longer in use are moved back to the secondary table, leaving the Mayo stand limited to current-phase items. Tubing and cords must be positioned along the drape edge, secured with clamps if necessary, so they do not obstruct movement or compromise sterility.

Finally, the assistant should maintain awareness of the entire sterile field’s workflow. If suction tubing kinks, cautery cords loosen, or retractor handles slip, these should be corrected before the surgeon resumes dissection. By preventing avoidable disruptions, the assistant ensures operative efficiency and patient safety remain uninterrupted.

• Suction/Irrigation: If only one suction tip is available, prioritize the Yankauer for general clearance and supplement with bulb syringes for fine irrigation. Flush the tip with saline every 10–15 minutes to prevent blockage. If suction fails, sponges mounted on sponge sticks can substitute for fluid removal until the device is functional.
• Retraction: With limited retractors, rotate staff for manual retraction in 10–15 minute intervals to prevent fatigue. Gauze-wrapped forceps or towel clips can temporarily elevate wound edges. When self-retaining retractors are unavailable, two assistants may coordinate with opposing Army-Navy retractors for sustained exposure.
