Using Surgical Asepsis Urinary Care and Catheterization Lesa McArdle, RN Week 8 day 2 Asepsis Microorganisms These are tiny, usually microscopic, entities capable of carrying on living processes. They are naturally present on and in the human body, as well as in the environment. Many are harmless (nonpathogenic) and do not produce disease in most individuals. If an individual is highly susceptible to infection, the nonpathogenic microorganisms could be dangerous. There are also known microorganisms (pathogens) that do cause specific diseases or infections. Asepsis Infection Control This consists of the policies and procedures of a health care facility to minimize the risk of the spread of nosocomial or community-acquired infections to patients and other staff members. Control of infection is an important part of every action the nurse performs. Asepsis Asepsis Free of Pathogenic Microorganisms Medical Asepsis Inhibits growth and spread of pathogenic microorganisms Clean technique Surgical Asepsis Destroys all microorganisms and their spores Sterile technique Infection Process The chain of infection. Nosocomial Infections Exogenous Infection Endogenous Infection Infection caused by microorganisms from another person Infection caused by the patient’s own normal microorganisms becoming altered and overgrowing or being transferred from one body site to another Nosocomial infections are most commonly transmitted by direct contact between health personnel and patients or from patient to patient. Handwashing Performing a 2-minute handwashing. This is the most important and basic preventive technique for interrupting the infectious process. Handwashing Performing a 2-minute handwashing. Wash hands before patient care; after touching blood, body fluids, secretions, excretions, and contaminated items; immediately after gloves are removed; between patient contacts; and when otherwise indicated. Surgical Asepsis This requires the absence of all microorganisms, pathogens, and spores from an object. The nurse working with a sterile field or with sterile equipment must understand that the slightest break in technique results in contamination. This is practiced in the operating room, labor and delivery area, and major diagnostic areas, as well as at the patient’s bedside, when inserting IV lines or urinary catheters, or when reapplying sterile dressings. Surgical Asepsis Explain what the patient can do to avoid contaminating sterile items. Avoid sudden movements of body parts covered by sterile drapes. Refrain from touching sterile supplies, drapes, or the nurse’s gloves and gown. Avoid coughing, sneezing, or talking over a sterile area. Surgical Asepsis Principles of Sterile Technique A sterile object remains sterile only when touched by another sterile object. Only sterile objects may be placed on a sterile field. A sterile object or field out of vision or an object held below the waist is contaminated. A sterile object or field becomes contaminated by prolonged exposure to air. When a sterile surface comes in contact with a wet, contaminated surface, the sterile object or field becomes contaminated. Fluids flow in the direction of gravity. The edge of the sterile field or container is considered contaminated. Surgical Asepsis Opening Sterile Packages Sterile items are placed in plastic or paper containers that are impervious to microorganisms as long as they are dry and intact. Reusable supplies may be wrapped in a double thickness or in linen or muslin. Sterile supplies have dated labels or chemical tapes that indicate the date when the sterilization expires. If the integrity of the sterile package is questionable, the item should not be used. Surgical Asepsis Opening Sterile Packages Nurse performs a thorough handwashing. The supplies are assembled at the work area. Commercially packaged items are usually designed so that the nurse only has to tear away or separate the paper or plastic cover. The item is held in one hand while the wrapper is pulled away with the other. Care is taken to keep the inner contents sterile before use. Surgical Asepsis Preparing a Sterile Field When performing sterile procedures, the nurse needs a sterile work area that provides room for handling and placing of sterile items. A sterile field is an area that is free of microorganisms and is prepared to receive sterile items. The field may be prepared by using the inner surface of a sterile wrapper or by using a sterile drape. Creating a sterile field Placing items on a sterile field (From Potter, P.A., Perry, A.G. [2005]. Fundamentals of nursing. [6th ed.]. St. Louis: Mosby.) Surgical Asepsis Pouring Sterile Solutions A bottle containing a sterile solution is sterile on the inside and contaminated on the outside; the bottle’s neck is also contaminated, but the inside of the bottle cap is considered sterile. Before pouring the solution into the container, the nurse pours a small amount (1 to 2 ml) into a disposable cap or waste receptacle. This cleans the lip of the bottle and is referred to as “lipping.” Pour the solution slowly to avoid splashing. The bottle should be held outside the edge of the sterile field. Pouring Sterile Solutions A, Nurse stands well back from solution being poured into sterile receptacle. B, Receptacle receiving fluids is placed near edge of sterile table. Surgical Asepsis Donning Sterile Gloves Two Methods Open Used on general nursing divisions before procedures such as dressing changes or urinary catheter insertions Closed Performed when the nurses wear sterile gowns and is practiced in operating rooms and special treatment areas Surgical Handwashing Surgical Handwashing Closed gloving (From Potter, P.A., Perry, A.G. [2005]. Fundamentals of nursing. [6th ed.]. St. Louis: Mosby.) A, Grasp back of glove cuff with non-dominant hand, pull on with dominant hand B, Glove dominant hand in same manner C, Keep hand in sleeve and pull on glove Cleaning, Disinfection, and Sterilization Cleaning This is the removal of all foreign materials, such as soil and organic material, from objects. It generally involves the use of water and mechanical action with or without detergents. Contaminated disposable objects are usually discarded; reusable objects must be cleaned thoroughly and then either disinfected or sterilized. When cleaning equipment that is contaminated by organic material, the nurse applies a mask and protective eyewear and waterproof gloves. Cleaning, Disinfection, and Sterilization Disinfection It is used to destroy microorganisms, but it does not destroy spores. Solutions used are called disinfectants or bactericidal solutions. They are too strong for human skin and are used only on inanimate objects. The nurse should use clean gloves to protect the skin. Sterilization Method used to kill all microorganisms, including spores Two types Physical (uses heat or radiation) Steam under pressure, boiling water, radiation, or dry heat Chemical Gas Chemical solutions Iodine, alcohol, and chlorine bleach Urinary Catheter Insertion Standard Steps in Selected Skills All nursing skills must include basic steps for the safety and well-being of the patient and the nurse. See Handout in your Skills Portfolio Urinary care and catheterization Urinary Elimination This is a natural process that individuals take for granted until it is altered by some uncontrollable physiological factor. Patients may require physiological and psychological assistance from the nurse. Physiological support may require the use of an invasive procedure, such as insertion of a urinary catheter into the bladder. Psychological assistance may be needed to help the patient adjust to a visible urine collection drainage bag. Urinary care and catheterization Catheter This is a flexible tube that can be inserted into a vessel or cavity of the body to withdraw or instill fluids. Most catheters are made of soft plastic or rubber. Catheters may be used for treatment or diagnosis. Catheterization of the bladder involves introducing a urinary catheter through the meatus and urethra and into the urinary bladder. Maintaining adequate urinary drainage Urinary catheters are used to Maintain urine flow Divert urine flow to facilitate healing postoperatively Introduce medications via irrigation Dilate or prevent narrowing of some portions of the urinary tract May be used for intermittent or continuous drainage Urinary care and catheterization Maintaining adequate urinary drainage Urinary catheters may be introduced into the bladder, ureter, or kidney. The type and size of urinary catheter used are determined by the location and cause of the urinary tract problem. Catheters are measured by the French system (Fr). Urethral catheters range in size from 14 to 24 Fr for adult patients. Most commonly used size is 16 Fr Ureteral catheters are usually 4 to 6 Fr and are must be inserted by a physician.

Urinary care and catheterization (From Potter, P.A., Perry, A.G. [2003]. Basic nursing: essentials for practice. [5th ed.]. St. Louis: Mosby.) Drainage system must be below the level of the bladder. Urinary care and catheterization Self-Catheterization This is used for the patient who experiences spinal cord injuries or other neurological disorders that interfere with urinary elimination. Intermittent self-catheterization promotes independent function for the patient. Urinary care and catheterization Routine Catheter Care Perineal care and the cleansing of the first 2 inches of the catheter every 8 hours are expected at minimum. The use of powders or lotions on perineum is contraindicated. Assess the urethral meatus and surrounding tissues for inflammation, swelling, and discharge. Note amount, color, odor, and consistency of discharge. The urinary tubing and collection bag should be changed only if there are signs of leakage, odor, or sediment buildup. Check the drainage tubing and bag to ensure that no tubing loops hang below the level of the bladder, that the tube is coiled and secured onto the bed linen, and that the tube is not kinked or clamped. Urinary care and catheterization (From Elkin, M.K., Perry, A.G., Potter, P.A. [2004]. Nursing interventions and clinical skills. [3rd ed.]. St. Louis: Mosby.) Empty and record urine output from urinary catheter into clean graduated container. Urinary care and catheterization Discontinuing an Indwelling Catheter An indwelling catheter must be removed or changed after a certain period of time. Urinary catheters are monitored for necessity on a daily basis. Need for catheter must be documented daily. It may be removed and replaced by a new catheter or removed and the patient allowed to excrete urine via the normal route. Urinary care Bladder Training Involves developing the use of the muscles of the perineum to improve voluntary control over voiding; may be modified for different problems. In preparation for the removal of a urethral catheter, the physician may order a clamp/unclamp routine to improve bladder tone. For the patient with stress incontinence, instruct to perform Kegel exercises. For habit training, a voiding schedule is established. Managing Incontinence Urinary incontinence occurs because pressure in the bladder is too great or because the sphincters are too weak. Kegel exercises Bladder training Disposable adult undergarments or underpads
