Final answer:
The procedure performed after anesthesia likely included a plantar fasciotomy, incisions, retractor placement, and suturing, as part of the surgical management for diffused gangrenous inflammation in the patient's foot.
Step-by-step explanation:
After the administration of anesthesia, the procedure that was performed on the patient would involve various steps. Although the precise sequence of events isn't provided in the question, the procedures mentioned such as plantar fasciotomy, transverse incision, placement of a retractor, and closure with horizontal mattress sutures are all part of the typical surgical procedures involving the foot. Plantar fasciotomy is often performed to relieve tension or pressure from the plantar fascia, which could be associated with conditions such as plantar fasciitis. A transverse incision of the plantar heel may be involved in accessing the site for fasciotomy or other procedures. The use of retractors is a common part of surgeries as they help in holding back the incised skin or the tissues to expose the area needing surgery. Finally, suturing techniques like the horizontal mattress sutures are used for closing the surgical site, promoting healing while minimizing scar formation. In the context of the patient's diagnosis, the surgery aims to address the diffused gangrenous inflammation involving tissue necrosis, which may require debridement or removal of the necrotic tissue followed by reconstructive procedures like skin grafting.
