  1. Antibiotic indications for OS Tara Renton

  2. Antibiotic indications for OSPeri-operative Elective • Pre operative (A,C,D +E) • Amoxycillin Oral 2g • OR • Erythromycin Oral 1g • + Post operative (A,B, D and E) • 3 days Pen V or Amoxycillin 250mg TDS • Or 3 days Metronidazole 200mg TDS • Additional if recent Abs included above • Clindimycin600 mg TDS for 7 days warn pt pseudo membraneouscollitis

  3. Patients at risk post op infection due to immuno-compromise (A) Immature immunity infants Malnutrition older population Disease Diabetes Mellitis (type 1 and 2) Alcoholism Cirrhosis Renal failure Splenectomy Malignant tumours Leukaemia Lymphoma Myeloma Collagen disease HIV AIDS Pagets Medication Steroids Immunosuppressants/ chemotherapy organ transplant Bisphosphonates Radiation therapy • Remember • Kids may be prone to rapid spreading infections due to elevated metabolic rate • Dry sockets do not occur in kids • Multiple dry sockets may be a sign of pathology OR osteomyelitis

  4. Situations when the use ofAntibiotics is NOT necessary • For the prevention of infective endocarditis BSAC/NICE 2010 • When identification and removal of source with local infection is possible Ellis et al BDJ 2011 • Chronic well-localized abscess Ellis et al BDJ 2011 • Minor vestibular abscess Ellis et al BDJ 2011 • Dry socket RCS Eng Guidelines 1996 • Mild pericoronitis RCS Eng Guidelines 1996

  5. Antibiotics in OS are indicated for infections when; • For acute local infection where you are unable to remove the cause immediately • For rapidly spreading infection with systemic signs • For persistent, recurrent on responsive infection

  6. Principles of infection management • Identify patients at risk and prevent post op infections where possible • Removal of source (extirpation of pulp / extraction) • Incision and drainage (I+D) if not all pus drained @ extn or cellulitic spread with no obvious pus • Medical support if indicated • Antibiotics • Analgesics Culture + sensitivity (C+S) if indicated Recurrent / Non responsive infection Compromised host defenses Rapidly spreading local infection Evidence systemic infection Suspected Actinomycosis • Re-evaluation identify patient in trouble EARLY on for referral

  7. Patient in trouble • Systemic signs • Fever > 36.8c • Lymphadenopathy • Trismus • Rash • Raised WBC/ CrP • Systemic symptoms • Malaise • Dehydration • Difficulty swallowing,speaking or breathing

  8. Indications for Culture andAntibiotics Sensitivity Recurrent / Non responsive infection Compromised host defenses Rapidly spreading local infection Evidence systemic infection Suspected Actinomycosis

  10. Suggested protocol for PREVENTION of BONJ/ORN Pre administration of BPS Complete invasive procedures prior to IV bisphosphonates /radiation (? Short arch therapy, OHI, Fluoride RS, Corsodyl gel) AVOID extractions use RCT/extrusion where possible Remove dentures Regular dental check up If routine extn required after BPs taken Corsodyl 10 mls QDS pre and post operatively for all cases Low risk Oral BPs < 3 years no added risk factors (medical probs/steroids) Primary care extn with minimal trauma. Preop 2g Amoxycillin Mod risk BP /ORN Pt > 3 yrs Oral BPs in patients on steroids /smoker / concomittent immuno compromise. Preop 2g Oral Amoxycillin / post op Oral Amoxycilin or metronidazole 7 days High risk IV BPs previously 2 week preop Pentoxyfiline 400mg BD Vitamin E 1000IU / 4 weeks post op plus clindamycin Refs Marks et al 2007 NHS Evidence - oral health formerly a Specialist Library of the National Library for Health MHRA: Bisphosphonates and osteonecrosis of the jaw (2007) [view] Osteonecrosis of the jaw with bisphosphonates (2006) [view] FDA: Osteonecrosis of the jaw: important drug precaution (2005) [view] Bandolier: Bisphosphonates and jaw necrosis (2006)

  11. Suggested protocol for Management of BONJ/ORN Refer If more complex surgical treatment is required OR The patient presents with painful separated bone sequestrum Stage 2 case Attain CBCT of region Mx Corsodyl 10 mls QDS pre and post operatively for all cases IV BPs previously 2 week preopPentoxyfiline 400mg BD Vitamin E 1000IU / 4 weeks post op plus Clindamycin LA surgery should be undertaken with minimal trauma lifting sequestrum away with irrigation with corsodyl and minimal debridement and loose sutures. Review

  12. Suggested protocol for Management of OM • Multiple dry socket??? • CBCT of area (usually mandibular region) • Bone sequestrae not present • 6 weeks Clindamycin • Bone sequestrae present • LA removal and debridement of sequestrae • Preoperative Abs and Post op Abs • Review

A retrospective review of the medical records of adult patients with jaw OM was carried out. Among 46 cases of jaw OM, the cause was odontogenic in 32 (seven had recent dental implants and four bisphosphonate osteonecrosis), postoperative/post-traumatic in eight, and secondary to osteoradionecrosis in six. Clinical features were chronic in 91.3%. The infection was polymicrobial in 24/41 (65.9%). Viridans streptococci were the most commonly isolated agents. Among 26 viridans streptococci tested, 81% were susceptible to penicillin and 96% to fluorquinolones, but only 11.5% to clindamycin. Overall, 35/38 (92.1%) had at least one clindamycin-resistant isolate. Appropriate antibiotics were administered for a mean of 5.8 +/- 3.2 months. Beta-lactams were used in 19 cases and fluorquinolones in 14. Among 39 cases with long-term follow-up, only two relapsed. Currently, jaw OM is commonly related to osteoradionecrosis, dental implants, and bisphosphonates. In patients with prior antibiotics exposure, a high percentage of infections were caused by clindamycin-resistant microorganisms, thus, beta-lactams should be the antibiotic of choice. In penicillin-allergic cases, the new fluorquinolones, probably in combination with rifampin and/or clindamycin, could be a promising alternative

Antimicrob Agents Chemother 40(6):1403–1407, 1996. • clindamycin for the treatment of osteomyelitis because it shows a good penetration into the bone tissue • Oropharyngeal anaerobic infections may not respond to penicillin and thus require a drug effective against penicillin-resistant anaerobes (see below). Oropharyngeal infections and lung abscesses should be treated with clindamycin  or a β-lactam/β-lactamase combination such as amoxicillin/clavulanate In patients allergic to penicillin, clindamycin or metronidazole (plus a drug active against aerobes) is useful.
