A draping system provides a continuous sterile field between a patient incision area and one or more medical practitioners. The draping system has a quick release system incorporated into the drape that enables a medical practitioner to separate from the continuous sterile field without disrupting the sterile field around the practitioner or the patient. The draping system may include an abbreviated practitioner gown, a drain and an integral patient incision area or a flap for extending the continuous sterile field around to one or more additional operating room tables. A modular drape and gown system extends the sterile field beyond the operating table allowing practitioners to couple to the extended field. A tent provides an enclosed sterile field useful in mobile or other non operating room surgical environments. Integral lighting and information displays facilitate field surgical procedures.

Medical procedure related objects (e.g., instruments, supplies) tagged with transponders may be accounted for in a medical procedure environment via a medical object accounting system using a number of antennas, and optional readers. A first set of antennas may be configured to interrogate sterile fields and/or non-sterile fields which do not encompass a body of a patient to account for the objects proximate a start and an end of a medical procedure. Sterile fields may encompass working surfaces of tables and stands, typically used by nurses. Readers (e.g., symbol, RFID) may be employed. A database may be maintained with information including a current status of each instrument or supply, for instance as checked in or checked out. On notification of a discrepancy, a handheld antenna and/or second set of antennas may interrogate a volume encompassing a body of a patient for retained instruments or supplies. The system may be automatically configured (e.g., loading appropriate software) on communicative coupling of a device (e.g., antenna, reader, peripheral device).
