Management of the open abdomen (OA) has rapidly evolved over the last several decades due to the improved understanding of the underlying pathophysiology of patients with an OA, adoption of damage control surgery, and the use of temporary abdominal closure (TAC) techniques for this patient population. The TAC utilizing negative pressure has been successful for managing patients with an OA with improved time to closure. Recent studies have started to examine the use of TAC in conjunction with negative pressure wound therapy with instillation and dwell time (NPWTi-d) for the management of the OA. This case series illustrates the capability, safety, and clinical effectiveness of TAC/NPWTi-d with hypochlorous acid (HOCl) solution. Three successfully treated cases describe the use of NPWTi-d using HOCl solution for the management of patients with a septic OA. This initial experience suggests instillation of HOCl through the tubing set, in conjunction with the TAC device, is safe and easy to use. This technique decreased the need for more frequent OA lavages in the operating room (OR) after the index procedure, as well as the associated concomitant risks of transporting patients who are critically ill between the SICU and OR. No acute complications related to the TAC device with HOCl were noted. Based on the results of this study, the authors believe instillation through the TAC device may be the next evolution in the use of abdominal NPWT and programmed intermittent lavage of the peritoneal cavity represents an effective method in the care of patients with a septic OA.
