Clinical studies

The study clearly shows that NoseFrida, used in accordance with manufacturer recommendations is safe with respect to the risk of transmitting bacterial infection from the child’s nose to the user. There are no objections from a bacteriological or environmental hygiene aspect to the use of the nasal aspirator for children with increased nasal secretion production in connection with an upper respiratory tract infection.

Developed by ear nose and throat doctors

NoseFrida has been developed by doctors at the Ear, Nose & Throat Clinic at University Hospital MAS in Malmö and satisfies all the requirements for a good children’s nasal aspirator for multiple use. NoseFrida has been presented as a scientific contribution at the Swedish Medical Society’s national conference.

Clinical studies

Two clinical studies have been conducted by the Ear, Nose & Throat Clinic, University Hospital MAS Malmö, with paediatrician Dr Mette Veje in charge. The study was conducted at the Child Care Centre Södertull in Lund and at the Paediatrician’s Office, Slottsstaden’s Medical Team in Malmö. The study included 43 children; 17 girls and 26 boys.

42 of the children in the study had secretion stagnation and pronounced nasal congestion. The majority of the children (34) used NoseFrida more than 3 times a day, including before each meal, before the child was put to bed and if it awoke in the middle of the night. 37 of 40 parents thought using the aspirator was very positive. No complications were noted. The study has been published in the Swedish ÖNH journal 3/97.

Sleep improved for 80 % (32 of 40) children with sleeping difficulties

The effects of saline drops improved for 88 % (21 of 24) children

The effects of the saline drops and nasal spray improved

It was evident from the study that the effects of the saline drops and nasal spray improved significantly after the child’s nose had been cleaned using NoseFrida. The reason for this is that the medicine, after the use of NoseFrida, is able to exercise its effect more directly on the mucous membrane.

The hygiene filter effectively prevents the transmission of bacteria

A microbiological evaluation of NoseFrida has been conducted to investigate if there is any risk of spreading the bacteria from the child’s nasal flora to the person using the nasal aspirator. The bacteriological test was conducted at the Clinical Microbiological Laboratory in cooperation with the Children’s Clinic, both at University Hospital MAS in Malmö.

The survey used NoseFrida modified with a sterile filter inserted in the tube 7 cm from the suction opening. None of the patients tested had been under antibiotic treatment at the time of testing.

Cultivation has taken place at the Bacteriological laboratory UMAS. The sample has been immediately taken care of by the laboratory after the test and a separate cultivation has been made on the secretion in the tip of NoseFrida and on the sterile filter.

The study was conducted on 12 patients, all from the Children’s Clinic, and have in no cases shown any growth on sterile filters despite the growth of pathogens in the tip of the nasal aspirator in 10 cases. Cultivations from the tip of the nasal aspirator have in 10 cases shown to have bacteria that might cause other types of inflammation and pneumonia in the children. In two cases no growth was obtained from the tip or sterile filter.
