New Ringer's lactate gel formulation on nasal comfort and humidification.
Brazilian Journal of Otorhinolaryngology 2018 August 9
INTRODUCTION: The use of saline irrigation for nasal washes is a well established procedure in the treatment of sinonasal inflammation and infection. In addition to saline solutions, Ringer's lactate is also an efficient option for nasal washes and humidification.
OBJECTIVE: To assess the comfort, humidification and tolerance regarding stinging sensation, provided by sodium chloride nasal gel at the concentrations of 4.5mg/g and 6.0mg/g through questionnaires answered by the patients.
METHODS: A total of 60 patients, 56 females, aged between 22 and 66 years old (mean age of 47) and 4 males, aged between 36 and 66 years (mean age of 49), were included in the study for a period of 17 days (±2 days) treatment. The patients were monitored by a general practitioner throughout the study period. They were instructed to apply each product in both nostrils twice a day during a 7-day period (±2 days). The patients were evaluated prior to the use of the first product at visit 0 (V0), after 7 days of treatment (±2 days) at visit 1 (V1), after 3 days of product discontinuation at visit 2 (V2) and after 7 days (±2 days) of treatment with the second product, in visit 3 (V3).
RESULTS: A significant difference (5% significance) was observed regarding comfort and stinging sensation between the two different concentrations; comfort was higher and stinging was lower with the 6.0mg/g concentration gel. No difference in humidification was observed between the two treatments.
CONCLUSION: Ringer's lactate at the concentration of 6.0mg/g was superior to that at 4.5mg/g for parameters comfort and stinging sensation. No statistical difference was observed between the two products regarding nasal humidification.
