Answer

Because of the large surface area of the peritoneum, peritoneal lavage is highly effective as a cooling technique. This technique can produce core body temperature reductions of 0.5°C per minute or up to 5-10°C per hour. [5] An advantage of peritoneal lavage over gastric lavage is that patients do not need to be endotracheally intubated. However, peritoneal lavage does require equipment and skilled personnel to surgically place the peritoneal catheter.

While preparing for the placement of the peritoneal catheter, prepare the lavage by placing 2-8 L of normal saline into an ice bath.

Place a standard peritoneal catheter.

Instill and withdraw ice cold saline in 500-1000 mL increments until the patient’s core body temperature reaches 39°C.
