Page "Cholecystitis" Paragraph 47

Supportive measures are usually instituted prior to surgery.

These measures include fluid resuscitation and antibiotics.

Antibiotic regimens usually consist of a broad spectrum antibiotic such as piperacillin-tazobactam ( Zosyn ), ampicillin-sulbactam ( Unasyn ), ticarcillin-clavulanate ( Timentin ), or a cephalosporin ( e. g. ceftriaxone ) and an antibacterial with good coverage ( fluoroquinolone such as ciprofloxacin ) and anaerobic bacteria coverage, such as metronidazole.

For penicillin allergic patients, aztreonam and clindamycin may be used.
