Laminar flow enclosure-a possible risk to the patient.

A retrospective comparison was made between two groups of 50 adult patients who underwent open-heart surgery in an operating suite with two adjacent rooms, one of which was equipped with a laminar flow enclosure. Core and body surface temperatures were measured at 15-min intervals for the 1st h after commencement of surgery. Patients in a laminar flow enclosure showed a significantly greater decrease in core temperature with time. Possible means of counteracting this are suggested.
