NCM 112A: MEDICAL SURGICAL NURSING RLE - SL │ Prof. Mario 7:30 - 9:00 AM ThF (A504) Transes by: Christine Mae Antonio Unit 2: Intraoperative Phase Intraoperative Phase Tissue Forceps - From the time the patient is received from the operating room until admitted to the PACU Surgical Instruments - Surgical instruments can be generally divided into six classes by function: - Cutting instruments - Grasping or holding instruments - Haemostatic forceps (instruments used to stop blood flow) - Retractors - Clamps and distractors - Accessories and implants Mayo scissors and Kocher forceps Pean Forceps Richardson I. Cutting and Dissecting - Used to incise, dissect, and excise tissues - Cutting instruments have single or double razor sharp edges or blades, such as a scalpel, scissors, or osteotome. Dissecting instruments may have a cutting edge and come in a variety of designs. Examples include curettes, cone tip dissectors, and biopsy forceps. - The tips of the scissors should be pointing upwards when cutting a suture (the picture below is wrong) - Metzenbaum Scissors - Used to cut delicate tissue KNIFE HANDLES or Scalpel and blades - Deep knife - Handle 7 with blade 15 Used to cut deep, delicate tissue. - Inside knife - Handle 3 with blade 10 (used to cut superficial tissue. II. Clamping and Occluding - Skin knife - Handle 4 with blade 20 Used to cut skin. - Used to compress vessels and other tubular Blade holder #3 charged to surgical blade structures to impede or obstruct the flow of blood number 10-15-27 and other fluids. Blade holder #4 charged to surgical blade no. - These clamps are atraumatic ratcheted instruments 18-20 that are straight, curved, or angled and have a variety of inner jaw patterns. - The thumb and ring finger are inserted into the rings of the scissors with the index and middle finger used to guide the instrument. - The instrument should remain at the tip of the fingers for maximum control. SCISSORS - Straight Mayo Scissors - Used to cut suture and supplies. Also known as: Suture scissors. Mosquito - Used to clamp small blood vessels. Its jaws may be straight or curved. - Curved Mayo Scissors - Used to cut heavy tissue (fascie, muscle, uterus, and breast) Kelly Forceps - Used to clamp larger vessels and tissue Backhaus towel clip - Used to hold towels and drapes in place Right Angle / Mixter / Ninety - Used to clamp hard-to-reach vessels and to place sutures behind or around a vessel. A right angle with a suture attached is called a "tie on a passer" or stick Forester Sponge Stick / Spong or Ovum forceps - Used to grasp sponges Debakey Vascular Clamp Pickups, thumb forceps, tissue forceps - Available in various lengths, with or without teeth, and smooth or serrated jaws - Should be held like a pencil III. Grasping - Designed to grip and manipulate body tissues Used to stabilize tissue that is to be excised, dissected, repaired, or sutured - Tissue forceps are the non-ratcheted style often referred to as pickups or thumbs, have either smooth, serrated or interlocking teeth, and vary in size and shape according to use Bonney Forceps - Used to grasp tissue. Available in short and long - Used for grasping fascia during the closure of sizes. A "Judd-Allis" holds intestinal tissue; a "heavy abdominal surgery or for clusre and sutring of large allis" holds breast tissue orthopedic procedures, such as total knee and total hip replacement surgery Babock - Used to grasp delicate tissues (intestine, fallopian tube, ovary) - Available in short and long sizes Rongeur (Bone Cutter) Debakey forceps - Used to grasp delicate tissue, particularly in cardiovascular surgery Laryngoscope Single tooth forceps, many teeth forceps (top to bottom) Thumb forceps are used to grasp tough tissue (fascia, breast); either have many teeth or a single tooth. Single tooth forceps are also called "rat tooth forceps." Randall Needle Holders - Can be short, medium & long (top to bottom) Bone Hook Mayo-Hegar needle holders are used to hold needles when suturing. They may also be placed in the sewing category Oropharyngeal tube Senn Retractor Trocar Oro/ Nasopharyngeal Tube Hammer (Mallet) Endotracheal tube Bone Curette IV. Retracting and Exposing Instruments - Designed to hold back or pull aside wound edges, organs, vessels, nerves, and other tissues to gain access to the operative site - Generally referred to as retractors and are either manual (handheld) or self-retaining (stay open on their own) - Retractors have one or more blades used for holding back tissues without causing trauma and should not be confused with a cutting blade; usually curved or angled and may be blunt or have sharp or dull prongs; vary in size according to the depth of the wound and the area of placement Deaver retractor - Manual type is used to retractdeep abdominal or chest incisions; available in various widths Skin Hook Richardson Retractor - Manual type is used to retract deepabdominal or chest incisions Gelpi Retractor - Self-retaining type is used to retract shallow incisions Army Navy Retractor / USA / US Army - Manual type is used to retract shallow or superficial incisions Balfour with Bladder Blade - Self-retaining type is used to retract wound edges during deep abdominal procedures Goulet - Manual type is used to retract shallow or superficial incisions Baby Bennette Retractor Malleable or Ribbon Retractor - Elevating and retracting bone; common in the minor - Manual type is used to retract deep wounds; may be orthopedic instrument set bent to various shapes V. Suctioning `Frazier Suction Tip Weitlaner Retractor - Commonly used for orthopedic, neuro, and ENT - Self-retaining type is used to retract shallow incisions surgery Suction pole - Used to evacuate blood and debris in deep abdominal surgery and Cesarean sections Blunt - Round point with no cutting edge that is used in soft, friable tissue, liver, intestine, kidney, muscle and uterine cervix VI. Wound Closing Instruments A. Sutures - materials used to sew together tissues or to hold it together in place. 1. Absorbable Sutures Examples: Surgical gut, Collagen sutures, Synthetic absorbable sutures Skin staples Usually used on fast healing tissues since it - Alternative to suturing absorbs quickly such as stomach, colon, bladder - Frequently used for large skin closure and 2. Nonabsorbable Sutures. Examples: Silk, Cotton, anastomosis of hollow organs Nylon Used for tissues that are slow healing skin, - Does not involve stitching - time saving fascia, tendons - Staples are removed using a special extractor B. Surgical needles - Allows the suture to pass through the tissue. Skin Preparation before Surgery 1. Regular Cutting Cutting edge is in the INNER - Skin preparation is the removal of as many bacteria curvature and is used in skin closure, plastic as possible from the patient's skin, through shaving, surgery, subcutaneous tissue mechanical washing and chemical disinfection. 2. Reverse Cutting Cutting edge is in the OUTER - The purpose of topical skin antiseptic preparation is curvature and it is use for retention sutures skin to reduce the number of microorganisms in the closure fibrous tissue and ligaments field of operation - Prevent infection (SSI) - Skin prep aids in preventing SSIs by removing debris Regular Cutting from, and cleansing, the skin, bringing the resident and transient microbes to an irreducible minimum, and hindering the growth of microbes - Skin is our first line of defense against infection, but surgical incisions leave us vulnerable to microorganisms. That's why pre-operative skin preparation is essential to infection prevention efforts. - Surgical site infections (SSls) are a common and costly complication of surgery. - The goal of surgical site preparation is to remove Reverse Suctioning Cutting bacteria from the skin at the surgical site. - The first use of an antiseptic skin agent in surgery is credited to the English surgeon Joseph Lister (1827-1912). Prior to the mid-19th century, limb amputation was associated with an alarming 50% postoperative mortality from sepsis. (infection/contamination) - The most common skin preparation agents used today include products containing iodophors or chlorhexidine gluconate (CHG). Taper Point - There is recent evidence to suggest that - Pointed needle with no cutting edge and it is used combination alcohol-based antiseptic solutions are for soft tissue closure, GI suture, and fascia more effective than aqueous solutions at reducing - Rubber sheet the risk of SSls. - Gloves - Head and neck surgery presents a unique challenge for surgical site preparation.

The patient's arms should be tucked at the patient's sides with a bedsheet, secured with arm guards to sleds. Lithotomy Position - Used during vaginal repair, D&C, rectal surgeries and deliveries - The arms may be flexed and secured across the body or extended and secured on padded arm boards Fowler’s Position - Fowler's position is used for patients who have difficulty breathing because, in this position, gravity pulls the diaphragm downward, allowing greater chest and lung expansion. The head of the bed is angled between 45 and 60 degrees. Reverse Trendelenburg Position - A variation of the supine position in which the patient's head is tilted upward so that their feet are positioned down. Reverse Trendelenburg may be Modified Lateral Position used for stomach, gallbladder, and biliary tract - The patient lies on an unaffected side for kidney surgeries. surgery.

RNFA responsibilities may include handling tissue, providing exposure at the operative field, suturing, and providing hemostasis. - The entire process requires a thorough understanding of anatomy and physiology, tissue handling, and the principles of surgical asepsis. - The competent RNFA needs to be aware of the objectives of the surgery, needs to have the knowledge and ability to anticipate needs and to work as a skilled member of a team, and needs to be able to handle any emergency situation in the operating room (Fortunato, 2000; Rothrock, 1999). 4. Surgeon - The surgeon performs the surgical procedure and heads the surgical team. - He or she is a licensed physician (MD), osteopath (DO), oral surgeon (DDS or DMD), or podiatrist (DPM) who is specially trained and qualified. - Qualifications may include certification by a specialty board, adherence to Joint Commission on Accreditation of Healthcare Organizations (JCAHO) Roles and Responsibilities standards, and adherence to hospital standards and of the Scrub and Circulating Nurse admitting practices and procedures. 1. Scrub Nurse - Activities of the scrub role include performing a surgical hand scrub; setting up the sterile tables; preparing sutures, ligatures, and special equipment (such as a laparoscope); and assisting the surgeon and the surgical assistants during the procedure by anticipating the instruments that will be required, such as sponges, drains, and other equipment (Phippen & Wells, 2000). - As the surgical incision is closed, the scrub person and the circulator count all needles, sponges, and instruments to be sure they are accounted for and not retained as a foreign body in the patient. - Tissue specimens obtained during surgery must also be labeled by the scrub person and sent to the laboratory by the circulator. 2. Circulating Nurse - The main responsibilities include verifying consent, coordinating the team, and ensuring cleanliness, proper temperature, humidity, and lighting; the safe functioning of equipment; and the availability of supplies and materials. - The circulating nurse monitors aseptic practices to avoid breaks in technique while coordinating the movement of related personnel (medical, radiography, and laboratory) as well as implementing fire safety precautions (Phippen & Wells, 2000). - Nursing activities directly relate to preventing complications and achieving optimal patient outcomes. 3. Registered Nurse First Assistant (RNFA) - The registered nurse first assistant (RNFA) is another member of the operating room staff. Although the
