Deep head and neck infections: outcome following empirical therapy with early generation antibiotics.

In order to study the bacteriological profile, antibiotic sensitivity and outcome following empirical therapy with early generation antibiotics in patients with deep head and neck infection, a retrospective review of 42 patients admitted for drainage and intravenous antibiotic therapy was performed. Ludwig's angina was the commonest infection, with the most common organisms isolated being Group F ß-haemolytic (15%) and non-haemolytic (12.5%) streptococcus. All streptococci and anaerobic gram-positive cocci were susceptible to penicillin. S. aureus isolates were oxacillin-sensitive and enterococcus isolates were ampicillin-sensitive. All 42 patients received empirical therapy with either intravenous penicillin or its derivatives. In only three patients was a change of antibiotic required based on culture and sensitivity results. Early generation antibiotics appear ideal as empirical therapy for deep head and neck infection.
