Taser Removal 2
Taser Facts Brand name Electronic Control Weapon (ECW) Acronym from a 20 th century children s book Thomas A. Swift Electric Rifle Used to stun or incapacitate persons Provides a safer less than lethal force option 3
How Tasers Work Interferes with the ability of the brain to communicate with the muscles. Contacting the target on any body area leads to full incapacitation. Fires 2 small darts that act as electrodes Darts stay connected to the taser by thin conductive wires. When 2 darts stick a 5 second electrical charge is released. 4

How safe Extensive review of literature reveals injuries are associated with the fall and not from the electrical impulse. Do not cause cardiac arrhythmias when used appropriately and the exposure lasts for <15 seconds. High voltage with low wattage is the key to understanding the low electrical risk. Standard impulse setting is 5 seconds. Not risk free but a less lethal form of force. 8
Medical Considerations Threshold to induce ventricular fibrillation in a normal heart is 10-50 joules. Most tasers fire at 0.5 joules or less. The most popular model fires at 0.3 joules, 30 times less than the threshold. High risk populations Pregnant women Elderly persons Young children Visibly frail Heart disease Medical/mental crisis Persons under the influence of alcohol/drugs 9
Assessment Confirm taser is off and cartridge is disconnected from the device. General survey of the patient addressing any serious injury from the fall. Evaluate the anatomical location of barbs. High risk zones Head Eyes Ears Nose Mouth Neck Genital Spine Hands, feet and joints 10
Barb Removal Universal precautions Local anesthetic Stabilize the skin surrounding the barb with your dominant using hemostats firmly grasp the barb with the notch facing up, jerk in a smooth quick motion Visually examine the barb to ensure it is fully intact Taser barb is considered a sharp, take all precautions to avoid accidental needle stick 11
Barb Removal Place barb in an appropriate container and return to law enforcement officer for evidence. Cleanse wound with antiseptic and dress. Up date tetanus immunization Instruct patient on basic wound care and signs and symptoms of infection. 12
Conclusion Current medical literature does not support the need for routine laboratory studies, electrocardiograms or prolonged ED observation after electrical exposure from a Electrical Control Device in an otherwise asymptomatic awake and alert individual. 13
ANIMAL BITE WOUNDS 14
EPIDEMIOLOGY Difficult to determine actual numbers because many are not reported CDC reports that an average of 4.5 million bites per year 885,000 require medical attention In 2006, 31,000 underwent reconstructive surgery Children are the most frequent victims 15
PRINCIPLES OF DISEASE Bites are traumatic injuries that cause damage to skin, muscle, nerves, blood vessels, tendons, joints and bones Wounds can be lacerations, contusions, scratches, tear or deep punctures Contamination with oral flora makes local wound infection the principle treatment concern along with rabies and tetanus immunization status Most US cities have animal bite reporting laws 16
CLINICAL MANAGEMENT Prevention and treatment of local bacterial infection and prevention, recognition and management of subsequent systemic illness Initial assessment for life threatening injury Meticulous exam and wound cleaning Special attention to wounds that involve joint space penetration 17
CLINICAL MANAGEMENT Facial, hands, and perineum wounds can be problematic due to the close proximity of delicate structures Image wounds if there is any suspicion of a foreign body Primary closure for cosmetic and functional issues Delayed primary closure is most successful Tetanus and Rabies immunization evaluation 18
HELICOPTER ACRONYM H E L I C O P T E R History Examination Liberal cleansing Irrigation Closure & culture consideration Operative cleansing and closure Prophylactic or therapeutic antimicrobial use Tetanus immunization status Elevation Rabies risk 19
TETANUS PROPHYLAXIS 20
RABIES PROPHYLAXIS Rare disease in developed countries Significant North American reservoirs of animal rabies exists in bats, skunks, raccoons and foxes. All carnivores and omnivores are potential vectors http://www.cdc.gov for updated information 21
RABIES PROPHYLAXIS DOG AND CAT BITES Condition of animal at time of attack Treatment of exposed person Healthy and available for 10 day observation No treatment unless animal develops rabies Rabid, suspected rabid, or escaped RIG and HDCV 22
RABIES PROPHYLAXIS Animal species Wild Skunk, bat, fox, raccoon, bobcat, and other carnivores Condition of animal at time of attack Regard as rabid Treatment of exposed person RIG and HDCV Bites from squirrels, hamsters, guinea pigs, gerbils, chipmunks, rats, mice, rabbits and hares almost never call for rabies prophylaxis. Consult local public health officials. 23
RABIES IMMUNOGLOBULIN (RIG) 20 IU/kg of body weight If anatomically feasible up to half the dose should be infiltrated around the wound and the rest administered in the gluteal area RIG should not be administered in the same syringe or into the same anatomic site as the vaccine because RIG may partially suppress active production of antibody 24
RABIES VACCINE (HDCV) HDCV 1 ml IM deltoid area on Day 0 Day 3 Day 7 Day 14 25
ANTIMICROBIAL TREATMENT All puncture wounds Bites involving hands, feet, face, or genital area Moderate or severe wounds All wounds in immunocompromised patients Bite wounds with signs of infection 26
PROPHYLACTIC ANTIBIOTICS Refer to the Sanford Guide to Antimicrobial Therapy or other source for specific bites Overall initial therapy for most bites and those not allergic to penicillin is Amoxicillin-Clavulanate Alternative combinations vary with specific animals 27
BATS Most recent human rabies has been caused by bats Contact with bats increases suspicion of rabies exposure Consult local health department and CDC Rabies is not transmitted by bat guano, urine or blood 28
DOG BITE 5-6 % become infected Pastaurella and anaerobes most common microorganism Capnocytophaga canimorsus rare but fulminant bacteremia following a dog bite 29
CAT BITES 60-80 % become infected Narrow sharp teeth increase the susceptibility to deliver infectious agents through puncture wounds Pastaurella Multocida most common microorganism Cat scratch disease 7-12 days after bite or scratch 30
HUMAN BITES 31
HUMAN BITE WOUNDS AND CLOSED FIST INJURIES (CFI) Associated with a high incidence of infection, approximately 60%, especially with hand injuries Polymicrobial, staph and strept species Eikenella Corrodens common bacteria If blood involved hep B and HIV prophylaxis may be warranted CDC post exposure prophylaxis 24 hour hot line, 1-888-448-4911 for consultation 32
FERRET BITES 3rd most popular pet in the US Usually attack face and neck Little is known about the bacteriology of ferret bites CDC recommends management strategy similar to that for other domestic animals, 10 day observation. 33
DOMESTIC HERBIVORES 34
HORSES AND PIGS Pigs and horses can inflict serious injury with their powerful jaws and grinding teeth Usually require careful debridement and exploration High risk of infection Polymicrobial 35
RODENT BITES Usually trivial No rabies Rat bite fever- 2 similar febrile illnesses diagnosis confirmed by blood culture for streptobacillus moniliformis or spirillum minus rare Hantavirus is also rare transmission 36

Tonopen 43
CHEMICAL BURNS Serious damage arises from strong basic and acidic compounds Severity is related to type of substance, volume, concentration, duration and mechanism Treatment goals- aggressive early management and close long term monitoring 44
Chemicals Acidic Battery acid (e.g., sulfuric acid) Bleach (e.g., sulfurous acid) Glass polish (e.g., hydrofluoric; behaves like alkali) Vinegar (e.g., acetic acid) Chromic acid (brown discoloration of conjunctiva) Nitric acid (yellow discoloration of conjunctiva Alkaline Cleaning products (e.g., ammonia) Fertilizers (e.g., ammonia) Drain cleaners (e.g., lye) Cement, plaster, mortar (e.g., lime) Airbag rupture (e.g., sodium hydroxide) Fireworks (e.g., magnesium hydroxide) Potash (e.g., potassium hydroxide) 45
MANAGEMENT Remove offending agent Irrigation Must contact ocular surface to be effective 1-2 liters Morgan lens Test ph Rx artificial tears Pain management Close ophthalmologic follow up 46

RING REMOVAL Remove all rings before edema!!!! Methods Lubrication String method Cut Consider anesthesia 51
RING CUTTER 52
STRING METHOD Wrap a Penrose drain circumferentially proximal to distal 20-25 in piece of string Pass string under ring Wrap proximal to distal not allowing any skin to protrude Grasp proximal end, turn clockwise 53
FISHHOOK REMOVAL 54
The Problem is. 55
Fishhooks Variety of shapes and sizes Barb is a projection extending backward from the point of the hook. 56
Fish Hook Removal Several methods for successful removal Strategy depends primarily on the depth of the hook Caution to be taken for removal of a hook with multiple barbs Anesthetize the area either locally or by a digital block depending on location 57
Simple Retrograde Technique Press skin over tip of hook to disengage barb while apply pressure downward on shank Back the hook out of the skin Most simple but least effective 58
String Pull Method Variation of retrograde technique String is wrapped around the bend of the hook where it enters the skin End of the shank is depressed with one hand to disengage the barb. The other hand gives a quick pull on the string 59
Needle Cover Technique Requires dexterity 18g needle is inserted into the entrance wound along side of the shank Needle follows the hook until the lumen covers the barb The hook and needle are withdrawn from the wound as a unit 60
Advance & Cut Technique Useful for deep penetration and large hooks Tip is advanced through the skin Once exposed tip and barb are cut with wire cutters The remaining part is rotated back out of the wound 61
62
Incision Technique Modified needle cover technique Used for hooks embedded in dermis or in delicate areas Enlarge of wound with a #11 scalpel, follow the bend of the hook until the barb is disengaged from the tissue Withdraw hook through the wound 63
Arthrocentesis & Joint Injection The Basics
Arthrocentesis Aspiration of fluid from a joint space May be diagnostic or therapeutic Generally presents few complications Joint injection may occur after fluid removal or may be performed as a separate procedure
Indications Diagnosis of non-traumatic joint disease Relief of pain Removal of effusion Local infiltration of medication Diagnosis of bony or ligament injury Establishment of intra-articular fracture Obtain fluid for culture & cell study
Contraindication Absolute Overlying infection Cellulitis Abscess Suspected bacteremia Steroid injection Septic joint Relative Recent fracture Osteoporosis Anticoagulants Bleeding disorders
Requirements Always ensure complete H&P before procedure X-Rays? Check for allergies Previous joint aspirations or injections? Informed consent
Decisions Aspirate? Inject? Both?
Fluid Analysis Observation Chemical Analysis Microscopic Study Bacterial Culture Serologic Study Polarized Light Microscope
Synovial Fluid Analysis Fluid grossly assessed as clear, turbid or bloody Most important to distinguish between inflammatory and infectious causes Normal synovial fluid is Straw, clear enough to read newspaper Flows freely consistency of motor oil Gives positive string test
String Test Simple test for fluid viscosity Viscosity correlates with hyaluronate Inflammation degrades hyaluronate which becomes lowers viscosity Measure fluid string from falling drop of gloved finger Normal fluid = 5-10cm string Inflammation = short string or multiple drops
Specimen Collection Cell count and cytology lavender top tube (EDTA) Chemistries, serology and viscosity red top tube ( no additive) Crystals green top tube(sodium heparin) or immediate visualization under microscope
Specimen Collection GC culture medium, low oxygen level Culture appropriate medium
Synovial Fluid Analysis Indicator Normal Inflammatory Infectious Gross Appearance Clear Transparent Yellow Clear-slightly turbid Yellow Cloudy String Sign Normal Diminished Diminished WBC/mm3 <200 <200 >2000 Culture Negative Negative >50% positive Crystals Negative Positive Negative
Common Joint Injection Sites Knee* Hip Ankle Shoulder* Glenohumeral joint Acromioclavicular joint Elbow* Lateral epicondyle Medial epicondyle Hand and Wrist Thumb* Trigger finger* wrist

Stop Cock
Procedure Thorough H & P Position patient optimally Knee fully extended with relaxed quadriceps Elbow flexed 90 degrees, forearm pronated, palm flat on table Spend time to find anatomical landmarks!!!!!!
Procedure Aseptic technique Clip thick hair Area thoroughly scrubbed Bactericidal agent x 3 Medial to lateral aspect in circular motion Allow to dry between scrubs Clean area with alcohol Sterile gloves and equipment
Procedure Anesthesia for Site Vapor coolant 1% or 2% Lidocaine (rapid onset; 1-2 hrs) OR Bupivacaine (5 minutes; 2-4 hrs) OR Diphenhydramine OR Ice
Procedure Identify Landmarks!! Use larges practical needle 18 gauge aspiration 25 gauge for injection Use appropriate syringe 30cc or 60cc for aspiration Insert needle, pull back on plunger, enter joint space
Procedure Withdraw all fluid Use hemostat or stopcock to change syringe Assess fluid and transfer into container Cell count, culture, slide, string test If injecting change syringe and inject Withdraw needle and apply dressing
Potential Complications Infection Introduction Masking with steroid Steroid arthropathy Post injection inflammation (steroid flare 12-48 hours)
Potential Complications Bleeding and blood vessel trauma Peri-articular complications Tendon rupture Soft tissue atrophy Systemic responses Elevated BS Peripheral flushing
Follow-Up Band-Aid Rest, Ice, Elevation, Compression Limited weight bearing for 48 hours Consider knee immobilizer NSAID or other analgesic Instructions for signs of infection
Conclusions When performed correctly, arthrocentesis is a relatively safe procedure that is used to obtain valuable diagnostic information and provide therapy for acute joint disease. The key to success is strict adherence to sterile technique, observance of anatomic landmarks and proper preparation of synovial fluid for examination.
