A Simple Solution to Lens Fogging during Robotic and Laparoscopic Surgery

We have routinely used FRED antifog solution (US Surgical, North Haven, CT), which consists of less than 15% isopropyl alcohol, 2% surfactant, and more than 85% water, during laparoscopic procedures.1 We also use the Insuflow (Lexion Medical, St. Paul, MN) device. Insuflow is a single-use device that attaches to the outlet port of an insufflator and is designed to warm and humidify the gas stream prior to insufflation into the abdominal cavity to prevent drying of peritoneal surfaces and to improve recovery time.2–4 The Insuflow device consists of a disposable filter heater/humidifier tubing set and a control module that houses the control and safety circuits for the system.5 Gas from the insufflator flows into the Insuflow device, through the in-line filter, continues along the tube to enter the Insuflow device cassette that contains the heating element and humidification media.
