RT Journal Article SR Electronic T1 Flexible fiberoptic brnchoscopy through the laryngeal mask airway in a small premature infant: It is accesible via pediatric 3.7 mm bronchoscope JF European Respiratory Journal JO Eur Respir J FD European Respiratory Society SP P1241 VO 42 IS Suppl 57 A1 Ahmet Hakan Gedik A1 Erkan Cakir A1 Ufuk Topuz YR 2013 UL http://erj.ersjournals.com/content/42/Suppl_57/P1241.abstract AB Childhood flexible bronchoscopy (FB), 0 age up to 18 years, can be used safely for wider indications in children of different weights and ages. Ultra-thin bronchoscope is used for premature or newborn infants. They are of limited diagnostic value when excessive bronchial secretions obstruct the view of the working field due to the absent of the suction channel. Besides, bronchoalveolar lavage can not be evaluated, and these bronchoscopes can not be used theurapeutically in some cases such as atelectasis. 3.5, 3.7, 3.8 mm in diameter pediatric bronchoscopes have suction channels. The use of bronchoscope with suction channel, especially in patients under 2.5 kg may lead to problems when the nasal mucosa is narrow. In addition, it may cause bronchospasm and hypoxia in small infants during procedure beacuse almost completely obstruct the airway. Laringeal mask airway (LMA) can prevent both bronchospasm and hypoxia as it does not need nasal route beside allowing positive pressure ventilation during the procedure. The FB with 3.7 mm bronchoscope through LMA of a 1910 gr and 75 day old premature baby who had atelectasis was performed succesfully in our clinic and no complication was seen. Our case was presented due to being the first performed and reported case in the literature of FB with 3.7 mm bronchoscope through LMA in a small premature baby with this weight.
