Several methods to reduce surgical site infections include inserting a surgical access device into an incision, retracting tissue, and introducing fluid into the surgical access device such that the fluid exits the surgical access device and irrigates a surgical site. Other methods do not include introducing fluid into a surgical access device but include suctioning a fluid into the surgical access device and removing the fluid from the body.

The method of claim 1, further comprising expanding the second retention member whereby expanding the second retention member causes the pliable membrane to retract tissue around the incision. 3. The method of claim 1, wherein a first group of one or more perforations are fluidly isolated from a second group of one or more perforations. 4. The method of claim 1, wherein the plurality of joined locations form a plurality of chambers, the method further comprising passing the fluid through some of the chambers without passing the fluid through other chambers. 5. The method of claim 1, further comprising supplying the fluid to the pliable membrane by passing the fluid through an inlet conduit fluidly coupled to the pliable membrane. 6. The method of claim 1, further comprising maintaining patency between the inner and the outer layers by providing a porous or non-porous material disposed therebetween, wherein the porous or non-porous material maintains patency when a compressive force is applied to the inner and the outer layers. 7. The method of claim 6, further comprising retaining the fluid in the porous or non-porous material. 8. The method of claim 6, wherein the porous material or the non-porous material facilitates fluid flow between the inner and the outer layers. 9. The method of claim 1, further comprising maintaining patency between the inner and the outer layers by providing a compressible or an incompressible material disposed therebetween, wherein the compressible or incompressible material maintains patency when a compressive force is applied to the inner and the outer layers. 10. The method of claim 1, wherein irrigating comprises selectively delivering the fluid to one or more perforations. 11. The method of claim 1, further comprising controlling fluid flow from the perforations with one or more valves fluidly coupled thereto. 12. The method of claim 1, further comprising applying suction to the surgical site to remove fluid therefrom through the plurality of perforations. 13.

The method of claim 13, further comprising expanding the second retention member whereby expanding the second retention member causes the pliable membrane to retract tissue around the incision. 15. The method of claim 13, wherein the plurality of joined locations form a quilted pattern. 16. The method of claim 13, wherein the plurality of joined locations form a plurality of chambers, the method further comprising passing the fluid through some of the chambers without passing the fluid through other chambers. 17. The method of claim 13, further comprising supplying the fluid to the pliable membrane by passing the fluid through an inlet conduit fluidly coupled to the pliable membrane. 18. The method of claim 13, further comprising maintaining patency between the inner and the outer layers by providing a porous or non-porous material disposed therebetween, wherein the porous or non-porous material maintains patency when a compressive force is applied to the inner and the outer layers. 19. The method of claim 18, further comprising retaining the fluid in the porous or non-porous material. 20. The method of claim 18, wherein the porous material or the non-porous material facilitates fluid flow between the inner and the outer layers. 21. The method of claim 13, further comprising maintaining patency between the inner and the outer layers by providing a compressible or an incompressible material disposed therebetween, wherein the compressible or incompressible material maintains patency when a compressive force is applied to the inner and the outer layers. 22. The method of claim 13, wherein irrigating comprises selectively delivering the fluid to one or more perforations. 23. The method of claim 13, further comprising controlling fluid flow from the perforations with one or more valves fluidly coupled thereto. 24. The method of claim 13, further comprising applying suction to the surgical site to remove fluid therefrom through the plurality of perforations. 25. A method for irrigating a surgical site in patient's body, said method comprising: providing a surgical access device, wherein the surgical access device comprises a first retention member, a second retention member, and a pliable membrane coupled to the first and second retention members, wherein the pliable membrane comprises an inner layer and an outer layer joined together at a plurality of locations, and wherein the outer layer comprises a plurality of perforations;maintaining patency between the inner and the outer layers by providing a porous or non-porous material disposed therebetween, wherein the porous or non-porous material maintains patency when a compressive force is applied to the inner and the outer layers;advancing the first retention member into the body through an incision;disposing the second retention member outside the body;irrigating the surgical site with fluid delivered from the plurality of perforations. 26. The method of claim 25, further comprising expanding the second retention member whereby expanding the second retention member causes the pliable membrane to retract tissue around the incision. 27. The method of claim 25, wherein the plurality of joined locations form a quilted pattern. 28.
