Pin-site infection

Improved pin-site care may be sufficient to treat mild inflammation (eg slight erythema, minimal exudate) at the site of orthopaedic pins and wires. Treat superficial infection (eg increased erythema, warmth, exudate or pain at the pin site) with a short course of antibiotics targeting Staphylococcus aureus, and seek expert orthopaedic advice for consideration of pin removal. Swab exudate for culture. While awaiting the results of culture and susceptibility testing, use:

1dicloxacillin 500 mg (child: 12.5 mg/kg up to 500 mg) orally, 6-hourly for 7 days. For dosage adjustment in adults with kidney impairment, see dicloxacillin dosage adjustment dicloxacillin dicloxacillin dicloxacillin

OR

1flucloxacillin 500 mg (child: 12.5 mg/kg up to 500 mg) orally, 6-hourly for 7 days. For dosage adjustment in adults with kidney impairment, see flucloxacillin oral dosage adjustment. flucloxacillin flucloxacillin flucloxacillin

Cefalexin is often preferred to dicloxacillin and flucloxacillin in children because the liquid formulation is better tolerated. It can also be used for patients who have had a nonsevere (immediate or delayed) hypersensitivity reaction to a penicillin1. Use:

1cefalexin 500 mg (child: 12.5 mg/kg up to 500 mg) orally, 6-hourly for 7 days. For dosage adjustment in adults with kidney impairment, see cefalexin dosage adjustment cefalexin cefalexin cefalexin

OR if adherence to a 6-hourly regimen is unlikely in a child

1cefalexin 20 mg/kg up to 750 mg orally, 8-hourly for 7 days2.

For patients who have had a severe (immediate or delayed)3 hypersensitivity reaction to a penicillin, use:

clindamycin 450 mg (child: 10 mg/kg up to 450 mg) orally, 8-hourly for 7 days.clindamycinclindamycinclindamycin

Modify therapy according to the results of culture and susceptibility testing.

If there are systemic symptoms or pin loosening, or if signs of infection fail to respond to a short course of oral antibiotic therapy, seek expert orthopaedic advice.

1 Cefalexin may be used in patients who have had a nonsevere (immediate or delayed) reaction to amoxicillin or ampicillin. However, because cross-reactivity between these drugs is possible, consideration should be given to the extent of the reaction, patient acceptability, and the suitability of non–beta-lactam options.Return
2 Unpublished pharmacokinetic and pharmacodynamic modelling data for cefalexin show similar levels of target attainment with the 6- and 8-hourly regimens above. It is the consensus view of the Antibiotic Expert Group that either regimen can be used for children.Return
3 Severe immediate hypersensitivity reactions include anaphylaxis, compromised airway, airway angioedema, hypotension and collapse. Severe delayed hypersensitivity reactions include cutaneous adverse drug reactions (eg drug rash with eosinophilia and systemic symptoms [DRESS], Stevens–Johnson syndrome/toxic epidermal necrolysis [SJS/TEN], severe blistering or desquamative rash), and significant internal organ involvement (eg acute interstitial nephritis).Return
