Intraoperative Surgical First Assisting Techniques
Sterile discipline and tissue handling
Intraoperative first assisting balances exposure, hemostasis, and tissue protection. Maintain the sterile field: gown and glove without contamination, keep hands above waist and below shoulders, never turn your back, and pass sharps through a neutral zone or on a tray. Anticipate the surgeon's needs by knowing the sequence: incision, exposure, hemostasis, repair, closure, dressing. Use gentle retraction, moist packs, and judicious electrosurgery to limit tissue necrosis. Know suture choices-absorbable (polyglactin, poliglecaprone, chromic) versus nonabsorbable (nylon, silk, polypropylene)-and match needle and suture to tissue. Assist with knot tying, suction, camera holding, and stapling while keeping the field clear.
Counts and specimens
Counts of sponges, sharps, and instruments are performed before the procedure, before closure of a cavity, and at skin closure. Report discrepancies immediately and do not close until resolved. Label specimens with patient identifiers, site, and orientation, and hand them off per policy. Handle drains and implants according to manufacturer instructions.
Trap: a stem may describe reaching across the sterile field or recapping a needle by hand; both are unsafe. Another trap is assuming an absorbable suture is appropriate for fascial closure-fascia generally requires slow-absorbable or nonabsorbable suture.
Rule of thumb: “expose, protect, control, close”-and when sterility is questionable, consider the item contaminated.
