Abstract | Study objective:
To evaluate the relationship between the adequacies of effective empirical antimicrobial
therapy for severe necrotizing fasciitis involve extremities and clinical outcome among
patients required ICU admission.
Design: Retrospective Study
Setting: A medical and surgical ICU (18beds) from a government tertiary referral
hospital
Results:
Between 1 Jan 2006 to 31 December 2010, 32 patients were admitted consecutively to
intensive care unit and diagnosed suffering from necrotizing fasciitis of their
extremities. . The mean age was 63 + 11.96 year old. Most patients had documented
preexisting medical conditions(75%); the most common was diabetes mellitus in 12
patients (37.5%). 26 patients (81.25%) admitted to our unit for post operative care, while
the rest were admitted for treatment of acute organs failure. A single causative organism
was identified in 27 patients (84.4%). The most common organisms isolated were
Streptococcus Pyogenes, Vibrio Vulnificus and Aeromonas species. 75% of patients
suffered from Vibrio species and 50% of Aeromonas species associated necrotizing
fasciitis had contact history with contaminated seawater/fresh water. Ten patients
(31.25%) patients in this study received ineffective empirical antimicrobial therapy. The
prolong duration between admissions to administration of effective antibiotic (hrs)
associated with amputation of their extremities (15.79 + 17.30 hrs verses 4.93 +/-11.99
hrs; with P value = 0.005). Patients received amputation also had significantly lower
hemoglobin level (9.03 gm/dl +1.72 versus 10.46gm/dl +1.77; P value = 0.036) and
received less operations (2.0 +1.03 verses 3.25 +1.95; P value =0.026). ICU mortality
was 37.5%. ICU nonsurvivors had statistically lower hemoglobin level, received less
operation, and had higher APACHE II scores. The crude mortality rate was 43.75%. Pre
existing diabetes mellitus, acute renal failure that required renal replacement therapy,
high APACHE II scores were factors associated with increase in hospital mortality.
Conclusion:
Prompt diagnosis and early administration of effective antibiotic, reduced morbidity.
Base on the bacteriologic findings, early use of board spectrum empirical antibiotics to
cover Streptococcus, Enterobacteriaceae; Vibrio and Aeromonas species in patients with
history of seafood and fresh/seawater contacted is recommended. |
