Use of Water Warming/Cooling Garment to Maintain a Constant Intraoperative Core Target Temperature in Patients Undergoing Cytoreductive Surgery With Hyperthermic Intraperitoneal Chemotherapy (HIPEC): A Proof-of-Concept Study

To look at the feasibility of using a water warming/cooling garment (called the ALLON system) to maintain a target body temperature during surgery and chemotherapy perfusion (a method of pouring chemotherapy throughout your abdominal cavity) without overheating or overcooling your body.

Objectives: Primary Objectives: To evaluate the feasibility of using a water warming/cooling garment (Allon system) to achieve and maintain a bladder temperature of ≥38°C for at least 30 minutes or longer during cytoreductive surgery with hyperthermic intraperitoneal chemotherapy while avoiding core (esophageal) hyperthermia (≥39.5°C). Secondary Objective: To evaluate the safety for all study participants when using of the Allon system strategy in achieving and maintaining a bladder temperature of ≥38°C for at least 30 minutes or longer during cytoreductive surgery with hyperthermic intraperitoneal chemotherapy while avoiding core hyperthermia (≥39°C)

The ALLON system water garment, is like a large apron that covers your body. There are tubes that run throughout the water garment, which allow warm liquid to flow so that the garment keeps the participant warm. The ALLON system water garment will be filled with warm water.

Water garments (Allon system) already pre-filled with warm water will be set up before induction of anesthesia. After the induction of general anesthesia, the water garment will cover the lower and upper extremities, the lateral portion of the chest, and the entire back of the patient, which accounts for 70% of the body surface. The water garment will be opened temporarily on the upper extremities for intravenous access and arterial line placement and will be continued intraoperatively until the patient is transferred from the OR table to the stretcher

Number of Patients to achieve and maintain a bladder temperature of ≥38°C for at least 30 minutes or longer.
