Thermoregulation • Heat loss occurs from: – Radiation – Convection – Conduction – Evaporation • 80% of heat loss is thru radiation and convection. Thermoregulation • Hypothermia causes problem intra and post operatively. • Vasoconstriction leading to increased blood pressure. • Shivering increases oxygen demand. • Damage to surgical repairs. • Strain on cardiovascular and respiratory systems. Thermoregulation • Reduce heat loss by: – Raising room temperature initially. – Overhead heater – Warm solutions. – Warm blankets. • Water circulating blankets • Forced air warming blankets Vital Signs • Baseline vital signs are taken before the procedure. • Temperature, pulse, respirations, and blood pressure are monitored during the procedure. Temperature • Hypothalamus controls body temp. • Several factors affect body temp. – Environment, age, health, time of day. • Can be monitored: – Orally – Rectally – Axillary Pulse • 2 phases of the heart. – Systole – Diastole • Measured by health care provider by palpating an artery. • Radial (wrist) –Most common • Apical (Apex of heart) - Stethoscope Pulse Points in the Body Bradycardia <60 BPM / Tachycardia >100 BPM Respirations • Exchange of O2 and CO2. – Internal and External • Rate, rhythm, and depth are monitored by the health care provider. • Normal adult 12-20 per minute. Blood Pressure • Pressure of the blood against the walls of the blood vessels. • Expressed as 2 numbers – Systole – Contraction of heart – Diastole – Relaxation of heart Blood Pressure • Measured by inflating a cuff around the upper arm of the patient and listening to the brachial artery. • 5 Phases • Systolic BP is recorded upon hearing first heartbeat. • Diastolic BP is recorded when the heartbeat sounds disappear. Circulator’s Sterile Tasks • Among the various non sterile duties of a circulator, some tasks require the circulator to don sterile gloves. – Urinary Catheter Insertion – Surgical Skin Prep Open Gloving • Open glove wrapper on suitable surface, touching only the outer edges. • Pinch 1st glove at the cuff and pull onto hand. • Using the 1st gloved hand, scoop the 2nd glove behind the sterile cuff and pull onto other hand. • Make adjustments only touching the sterile area of the glove with other sterile parts of the glove. Open Gloving Open Gloving Open Gloving Urinary Catheterization • Introducing a flexible tube into the bladder via the urethra, to drain the bladder of urine. • Physician’s order in needed. • Performed under sterile conditions. Urinary Catheterization • Indications: – – – – Decompression of bladder Drainage of urine Irrigation of the bladder Control bleeding Urinary Catheterization • Considerations: – Sterile technique – Size, style, and materials • Indwelling • Latex allergy – Balloon filled with sterile water – Drains by gravity – Secure to patients thigh Urinary Catheterization • Surgical techs may be called upon to insert a urinary catheter. • Sizes 8-30 French (14-16 Most common) • Various materials and types • Males in supine, Females should be “frog legged” Urinary Catheterization • Procedure: – – – – – Gather supplies Open sterile catheter kit Don sterile gloves Drape the patient Prepare catheter • Test balloon • Lubricate tip Urinary Catheterization • Procedure: – Clean urethral meatus with antiseptic • Females retract labia • Males retract foreskin if indicated – – – – Keep “contaminated” hand on genitalia Insert catheter until urine is seen flowing Inflate balloon Hang drainage bag Surgical Skin Prep • Performed to remove transient organisms, and reduce resident organisms from the patients skin. • Similar to surgical hand scrub by sterile team members. • Skin cannot be sterilized!! Surgical Skin Prep Solutions • Alcohol – Provides rapid, significant reduction in microbes. Drying effect. • Iodine - Provides rapid, significant reduction in microbes. May irritate skin. • Iodophors – Less irritating to skin. • Chlorhexidine – Reduction effect is not as rapid, but longer lasting. • Hexachlorophene – Must be used several days prior to surgery. Build up effect. Surgical Skin Prep • Considerations: – All necessary procedures are carried out prior to skin prep. – Site must be free of gross contaminates. – Do not let prep solution accumulate under the patient. – Patient allergies – Area to be prepped Surgical Skin Prep • Procedure: – – – – Check patient allergies. Gather supplies. Expose surgical site and place chux pads. Aseptically open prep kit on appropriate surface. • Mayo stand or Prep stand Surgical Skin Prep • Procedure: – Ask permission from anesthesia to begin prep. – Don sterile gloves using open glove technique. – Check expiration dates on solution and pour onto appropriate sponges. • Scrub solution on scrub sponges • Prep solution on paint brushes sponges Surgical Skin Prep • Procedure: – If abdominal prep, begin with cleansing the umbilicus with cotton tipped applicator. – Take scrub sponge with scrub solution and begin washing at the surgical site moving outward in a circular pattern. • Moving from clean to dirty • Ensure that soiled sponges are not brought back over an area already prepped. Surgical Skin Prep • Procedure: – After all scrub sponges have been used, pat the area dry with sterile towels provided. • Be sure not to contaminate. – Take a paint brush sponge, and begin applying prep solution to the surgical site moving outward in a circular pattern, using the same rules as the scrub sponges. • Continue with all paint brush sponges. Surgical Skin Prep • Procedure: – Without contaminating remove chux pads, and allow the prepped area to air dry. • Tips: – Do not allow prep solution to pool. – If a sponge becomes contaminated, discard and start with a new sponge. Surgical Skin Prep • Abdominal Prep Surgical Skin Prep • Left Chest/Breast Prep Surgical Skin Prep • Lower Extremity Prep – May have a tourniquet applied. Surgical Skin Prep • Upper Extremity Preps – May have a tourniquet applied. Surgical Skin Prep • Perineum/Vaginal Preps – May include internal vaginal prep. Hemostatis • Hemostatis is the arrest of the loss of blood or hemorrhage. • Occurs: – – – – Naturally Mechanical methods Thermal methods Pharmacological methods Natural Hemostatis • Hemostatis is produced naturally by clot formation (Coagulation) and vessel spasm (Vasoconstriction). • Injured blood vessels releases a Prothrombin activator. • Thrombin, calcium, and fibrinogen work together to form a clot. – Platelet plug Factors Affecting Hemostatis • Congenital preexisting disorder – Hemophilia • Acquired disorders – Liver disease – Anticoagulant therapy • Heparin – Aplastic anemia – Aspirin therapy • Discontinue 1 week prior to surgery Mechanical Hemostatis • Clamps – Hemostats – Vascular Clamps • Ligature – Using suture to tie off a blood vessel – Stick tie • Clips – Small stainless steel or titanium used to occlude the vessel Mechanical Hemostatis • Sponges – Laps, Raytex, Cottonoids – Used to absorb blood and apply direct pressure to bleeding areas • Pledgets – Small squares of Teflon felt – Used as suture buttresses exerting pressure on needle holes to promote clotting Mechanical Hemostatis • Bone Wax – Refined and sterilized bee’s wax. – Mechanical barrier to seal off oozing blood from bone. • Suction – Used during surgery to clear the surgical site of blood and body fluids. – Variety of sterile tips for different surgeries. Mechanical Hemostatis • Drains – Used post operatively to remove blood and fluid from wound. • Tourniquets – Often used during extremity surgery to keep the operative site “blood free”. – Careful application is needed. – Must be periodically deflated for longer surgeries. Thermal Hemostatis • Electrosurgery • Monopolar – Active electrode (Sterile) – Dispersive electrode (Grounding Pad) (Unsterile) • Bipolar – Forcep like tip – Does not require placing a grounding pad Thermal Hemostatis • Laser – Intense concentrated beam of light. – Able to cut and coagulate tissue with very little surrounding damage. – Follow all safety protocols when working with a laser. Pharmacological Hemostatis • Absorbable gelatin (Gelfoam) – Composed of collagen in pad or powder form. – Deposits fibrin over bleeding area. • Collagen (Avitene) – Absorbable powdery substance of 100% collagen. – Forms sticky fibrin material. Pharmacological Hemostatis • Oxidized Cellulose (Surgi-Cel) – Creates a rapid forming blood clot applied directly to the bleeding surface. • Silver Nitrate – Used to control cervical or nasal bleeding. • Epinephrine – Vasoconstrictor – Used with local anesthetics and Gelfoam. Pharmacological Hemostatis • Thrombin – Bovine origin blood clotting enzyme – May be used directly onto bleeding area, or used in combination with Gelfoam. Blood Loss • Blood loss intraoperatively is monitored by several methods: – Suction containers • STSR must keep track of amount of irrigation fluid used. – Weigh soiled sponges • If blood loss is determined to be significant, a transfusion may be ordered. Blood Transfusions • Blood typing and cross matching are needed to ensure proper match. • 4 types – A, B, AB, and O – RH + or RH – • Careful checks are completed before blood is given to patient to avoid hemolytic reaction. Blood Transfusions • Whole blood or blood products may be indicated. – Plasma – Packed Red Blood Cells – Platelets • Homologous (Donated) • Autologous (Stored patient blood) – Cell Saver machine Emergency Situations • The STSR must be able to anticipate emergency situations and prepare in advance. • This skill comes with time, but entry level techs must be able to recognize basic signs. • The STSR must be able to react in a quick and calm fashion. Emergency Situations • Indicators of emergency situations: – – – – – – Rapidly dropping blood pressure Cardiac dysrhythmia Changes in vital signs Chest pain/difficulty in breathing Changes in skin color/temperature Confusion/Disorientation Emergency Situations • Treatment includes – Ensure a patent airway and restore breathing. – Maintain or restore cardiovascular status. – Treat injuries: • Chest • Shock • Wound closure • Fractures • Vital sign monitoring • Reassurance and comfort for patient Emergency Situations • CPR – All healthcare providers must be familiar with this lifesaving technique. – Certification by AHA or Red Cross • Recert every 2 years – – – – A = Airway open B = Breathing C = Circulation D = Definitive treatment Emergency Situations • CPR in the O.R. – Primary responsibility of the STSR is to remain sterile and protect the sterile field. – Keep track of instruments and needles. – May be asked to do open chest massage. – Sterility may become secondary. Emergency Situations • Malignant Hyperthermia – Life-threatening, acute pharmagogenetic disorder, triggered by an anesthetic agent. – Rapid increase in body temperature – Unexplained tachycardia – Unstable BP – Muscle rigidity – May lead to renal failure, heart failure, or death. Emergency Situations • Malignant Hyperthermia Prevention – When patients have a predisposition to MH, nontriggering anesthetic agents are used. • Propofol • Vecuronium – Vaporizer, filter, circuit hoses are changed and/or flushed with oxygen to ensure removal. – Careful monitoring by anesthesia provider. Emergency Situations • Malignant Hyperthermia Treatment – Stop the triggering agent immediately – Surgery may be stopped ASAP • STSR must be ready for quick closure – Various cooling methods may be used. • Chilled peritoneal lavage • Packing patient in ice • Dantrolene is administered. Emergency Situations • Syncope – Sudden loss of consciousness – Caused by several factors: • Disorders of arterioventricular conduction • Ventricular asystole or fibrillation • Bradycardia – Notify physician – Protect from aspiration – Treat injuries Emergency Situations • Seizures – Grand Mal (Most common) • • • • • Loss of consciousness Convulsions Incontinence Pre seizure warning signs May have no memory afterwards – Petit Mal • Shorter in duration Emergency Situations • Seizures – Focal • Arise from motor and sensory nerves in brain. • Occur in patients with brain tumors and arteriovenous malformations. • Following all seizures patients may feel fatigued and may have no memory of the event. Emergency Situations • Seizure management – Primary duty of STSR is to protect the patient. – Maintain an airway • Aspiration risk • Mouth clenching – After seizure calm and reassure the patient. – Document Emergency Situations • Anaphylactic reaction – Exaggerated allergic reaction to a substance. • Local anesthetics • Contrast media • Latex – First signs are usually mild itching and swelling. – Leads to difficulty breathing due to bronchospasm and laryngeal edema. Emergency Situations • Anaphylactic treatment – Maintain airway and provide oxygen. – Myocardial infarction is possible. – Treat for possible shock. – Give epinephrine to reduce spasm and raise blood pressure. – Levophed to increase blood pressure • Key is to act quickly and be sure to check for any allergies before giving medications, etc. Review and Summary • • • • • • • • Preoperative routines / Consent Patient transportation and positioning Vital signs Open gloving Urinary catheterization Surgical skin prep Hemostatis Emergency situations
