Pre-hospital and Community Hospital use of antibiotics for treatment of sepsis in adults (Antimicrobial)
Administration of intravenous antibiotics in the community to patients with suspected sepsis is challenging. Many of the recommended antibiotic combinations in the current Management of Infection Guidance are not suitable for administration in the community setting as they include infusions and complex dose calculations according to renal function. The following information is designed for use by practitioners assessing and providing initial management of patients with suspected sepsis in the community. The agents chosen can all be given by bolus intravenous injection and some by intramuscular injection. A number of oral or per rectum options are also given.
Alternative option (if only have stock drugs in GP bag or OOHs centre)
Please note a change of dose for cefotaxime for sepsis - this is a consensus recommendation from Scottish Antimicrobial Prescribing Group. For further information on reconstitution see:
Indication | First line | Beta-lactam anaphylaxis |
Notes |
Meningitis | Benzyl penicillin 1·2g IV/IM OR ceftriaxone OR cefotaxime 2g IV/IM (for IM administration: administer as 2 separate 1g injections at separate sites and reconstitute with 1% lidocaine to reduce pain at the injection site) | Chloramphenicol* 25mg/kg IV | Doses as per existing guidelines |
Sepsis of unknown origin | Ceftriaxone OR cefotaxime 2g IV/IM (for IM administration: administer as 2 separate 1g injections at separate sites and reconstitute with 1% lidocaine to reduce pain at the injection site) | Chloramphenicol* 25mg/kg IV |
* Chloramphenicol injection should be held as stock in rural areas for use in patients with confirmed anaphylaxis to penicillin as use of cephalosporin not advised in these patients.
Preferred option (ONLY if a range of antibiotic injections are available)
Administer the most appropriate antibiotic available, preferably intravenously (IV), depending on likely sepsis source. This guidance applies in a community hospital setting where a greater range of medications are available. If intravenous access not available, administer intramuscularly (IM) (if drug suitable) or high dose oral if patient can take.
