Analysis of nasopharyngeal bacterial culture in children with adenoid hypertrophy

Objective To study the nasopharyngeal bacteria in children with adenoid hypertrophy. Methods Nasopharyngeal bacterial culture was conducted in 127 children( 3-14 years old from March 2013 to March 2014)with adenoid hypertrophy,hospitalized for surgery. They were divided into two groups,with the first group including 34 cases of simple adenoid hypertrophy with OSAHS( obstructive sleep apnea hypo-ventilation syndrome),and the second group consisting of 93 cases of adenoid hypertrophy and OSAHS merged with sinusitis and otitis media,the results were compared. Results The detection rate of bacteria from nasopharyngeal swabs in 127 cases of adenoid hypertrophy was 84. 3%,among which the first group accounted for 76. 5%,and the second group was87. 1%. Correlation existed between the detection rate of bacteria and patients' clinical symptoms,with much higher detection rate of bacteria found in children with otitis media and chronic sinusitis. Through χ2rest,significant difference of positive rates was revealed in bacterial culture of nasopharyngeal adenoids in both groups( χ2= 127,P 0. 05). Conclusion Nasopharyngeal pathogenic bacterial carrying rate is higher in children aged 3-14 with adenoid hypertrophy,particularly in children with chronic sinusitis or otitis media. The research results may provide etiological basis for late treatment course of children,and play a positive role in prevention and control of adenoid hypertrophy as well as infectious diseases at adjacent organs.
