a base sheet having an upper surface, a lower surface, and at least one opening;

an absorbent sheet being positioned on the upper surface of said base sheet and having at least one opening aligned with the opening of said base sheet; and

a transparent sheet attached to said opening of said base sheet and said absorbent sheet, wherein a fenestration is formed in the transparent sheet through which a surgical procedure may be performed when the drape is covering a patient.

2. The surgical drape of claim 1 wherein said absorbent sheet comprises non-woven fabric.

3. The surgical drape of claim 1 wherein said base sheet comprises polyethylene.

4. The surgical drape of claim 1 wherein said transparent sheet is hydrophobic.

5. The surgical drape of claim 1 wherein said transparent sheet comprises a low-density polyethylene film.

6. The surgical drape of claim 1 further comprising a layer of adhesive on a lower surface of said transparent sheet substantially surrounding said fenestration.
