Medical Management
The conventional medical treatment
involves the use of broad spectrum anitbiotics, antihistamines with or
without decongestants, and mucolytic agents in patients with uncomplicated
sinusitis. The choice of medications is based on the patient's medical
condition and there are times when the choice may be severely restricted,
due to another medical condition that patient may be experiencing.
In treating adult Sinusitis,
the antibiotics are usually chosen based on culture results or prudent
medical judgement. The choice would also vary with the immunological status
of the patient. In patients with cystic fibrosis, immotile cilia syndrome,
severe allergic diathesis, antibiotic resistance from previous medical
or surgical treatments, or the severely immunosuppressed, patients may
require careful evaluation in the choice of antibiotics. This may vary
depending on the extent of the disease and the general medical condition
of the patient. Streptococcus Pneumonia, Hemophilus Influenza and Moraxella
Catarhalis are the most commonly encountered organisms at the present
time and the antibiotics are chosen accordingly. Community acquired Sinusitis
with Beta Lactamase producing organisms require a careful selection of
antibiotics. This includes the use of Augmentin (containing Potassium
Clavulunate), Aminoquinolones which include Levaquin, Tequin
and Avelox. In patients where the response to oral antibiotics are
poor, intravenous antibiotics are recommended, based on culture results.
A practical introduction to the usage of intravenous antibiotics is suggested
by the author.
What follows is an algorithm
for antibiotic therapy for chronic Sinusitis, visualized for the

Effective Utilization
of IV Antibiotic Therapy for Chronic Sinusitis
Evaluations
|
| 1.
If pre-operative evaluation (+) for: Signs &/or Symptoms c/w chronic
sinusitis, should be confirmed by nasal endoscopy
and
- Chronic Rhinologic
Conditions:
- Cystic Fibrosis
- Immotile Cilia
Disorder
- Sampter's Triad
- Patient w/high risk
co-morbid factors:
- Immune Deficiency
- Diabetic Endarteritis
- Culture positive for
oral antibiotic resistant organisms
- Mucopyocele
- CT shows unequivocal
hyperostosis
- Fungal sinusitis (IV
Abx wanted as adjunctive therapy)
|
Pre-operatively:
To start 2 weeks prior
to surgery
to continue post-operatively for 4 weeks
|
| 2.
If intra-operative evaluation (+) for:
- Culture positive for
oral antibiotic resistant organism
- Mucopyocele
- Unequivocal hyperostosis
- Fungal sinusitis (IV
Abx wanted as adjunctive therapy)
|
Post-operatively:
To start as soons as
all arrangements are made
to continue for 4 - 6 weeks
|
| 3.
If post-operative evaluation (+) for:
- Persistant signs &/or
symptoms c/w chronic sinusitis
- Recurrent signs &/or
symptoms c/w chronic sinusitis
- Culture positive for
oral antibiotic resistant organism
- CT shows unequivocal
hyperostosis
and
No signs of anatomic
obstruction
|
Post-operatively:
To start as soons as
all arrangements are made
to continue for 4 - 6 weeks
|
| 4.
If (+) for any medical contraindications for surgery |
Medical contraindications
for surgery:
To start as soon as
all arrangements are made
to continue for 4-6 weeks
|
|
Timing of IV Antibiotics
- Arrangement made for
PICC line
Position confirmed with CXR
- Choice of Antibiotics:
Culture specific, or if culture are negative,
Polymicrobial therapy including anaerobes
|
Follow-up Visits
|
- Timing: To begin
2 weeks after initiation of IV Abx
- Perform: History
& Physical exam including nasal endoscopy
- Evaluation:
- If complete
resolution (symptoms and exam), continue IV Abx for
additional 2 weeks to complete therapy; then, remove PICC
- If partial
resolution (symptoms and exam), recommend additional
2 weeks of IV Abx.
Re-evaluation after a total of 4 weeks therapy
If complete resolution, remove PICC line
If partial resolution, see below
- If no improvement
(symptoms and exam),
culture or re-culture
consider anti-fungal therapy
consider changing and/or adding other Abx
Re-evaluation after another 2 weeks of therapy
- If complete
resolution (symptoms and exam), continue IV Abx
for additional 2 weeks to complete therapy; then, remove
PICC
- If still
with partial or no improvement,
re-culture sinuses after discontinuing all Abx for 1
week
Infectious disease consultation
Re-evaluation by allergist
Re-evaluation by immunologist
- At each follow-up
visit:
Patient fills SF-36 (quality of life) form, and
SNOT-21 (chronic sinusitis) form
|
For the first
year after therapy,
follow-up evaluations every 3 months and
on as needed basis
|
After first year
of follow-up,
Follow-up yearly, and
on as needed basis
