Surgical site infection (SSI) remains a major cause of postoperative morbidity following emergency laparotomy, particularly in contaminated and dirty/infected abdominal conditions. Systemic antibiotic prophylaxis alone often fails to achieve adequate local tissue concentrations at the incision site due to impaired perfusion, contributing to persistently high SSI rates in this population.
This trial evaluates subcutaneous infiltration of levofloxacin, a broad-spectrum fluoroquinolone with favorable tissue penetration, administered along the wound edges immediately prior to skin closure, as an adjunct to standard surgical and antibiotic management.
This study is investigator-initiated and will be conducted as a single-center trial within the Department of Surgery, Sylhet MAG Osmani Medical College Hospital.

Patients undergoing emergency laparotomy for dirty/infected surgical pathology
Patients with known hypersensitivity to levofloxacin or other fluoroquinolones
Pregnant women or lactating mothers
Patients with pre-existing severe renal impairment
Patients with pre-existing skin infection at the incision site
