Sauvalle M, et al. - Experts evaluated the impact of temperature in nasal lavages to estimate mucociliary clearance rates. Saccharin test-applying it in the inferior turbinate and timing the detection of its taste was used, to estimate mucociliary clearance rates before and after nasal lavages with saline solution at room (20 °C) or body (37 °C) temperatures. They studied 78 healthy subjects, with a mean saccharin test time of 13.88 min. Mucociliary clearance was improved by nasal lavages with saline solution as measured by saccharin test. Seemingly, temperature mattered, which should be taken into account when indicating nasal lavages to our patients.
