Cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) is an extensive procedure used to treat peritoneal carcinomatosis, which is either primary or secondary to other cancers (eg, ovarian, colorectal, appendiceal) that have metastasized to the peritoneum. Morbidity, mortality, and quality of life have improved for patients selecting CRS with HIPEC as a cancer treatment. At Holy Name Medical Center in Teaneck, New Jersey, an interdisciplinary team was established to plan and coordinate performing this new procedure in the OR. The team created a written protocol for implementing CRS with HIPEC before patients were scheduled for surgery. This article explores the perioperative facets of implementing CRS with HIPEC and discusses care of the patient undergoing CRS with HIPEC, with a focus on perioperative nursing considerations.
