Sažetak
Cilj istraživanja: Utvrditi incidenciju i definirati moguće komplikacije laringoskopije ultrabrzom kamerom te utvrditi incidenciju nemogućnosti cjelovitog prikaza glasnica tijekom pregleda. Materijali i metode: Prospektivna analiza 113 ispitanika kojima je učinjena laringoskopija ultrabrzom kamerom u dva uzastopna dana, s primjenom topikalnog anestetika i bez njega. Zabilježen je razvoj komplikacija i nemogućnost prikaza cijele duljine glasnica pri pregledu. Rezultati: Ukupno je zabilježeno 7 komplikacija (3,09% snimanja) u 6 ispitanika (5,3% ispitanika). Sve su komplikacije bile kratkotrajne i blagog oblika te nisu ostavile dugoročne posljedice. Nemogućnost prikaza cijele duljine glasnice tijekom pregleda opažena je u 3 ispitanika (2,65% ispitanika). Uslijed izraženog refleksa nadražaja na povraćanje pri pregledu u 7 ispitanika (6,19%) grkljan uopće nije bilo moguće prikazati. Primjenom topikalnog anestetika pri pregledu u navedenoj skupini u njih 4 (57,14%) uspjela se postići cjelovita vizualizacija glasnica. Zaključci: Rezultati naše studije pokazuju da je laringoskopija ultrabrzom kamerom sigurna metoda vizualizacije glasnica, uz rijetku pojavnost blagih, ograničenih komplikacija te u malom broju bolesnika nije primjenjiva zbog nemogućnosti prikazivanja cijele duljine glasnica. Potrebna su daljnja istraživanja za razvijanje preciznog algoritma pregleda, koji bi optimizirao i standardizirao laringoskopiju ultrabrzom kamerom te poboljšao toleriranje i olakšao izvođenje pretrage.
Summary
Aim of the study: To define possible complications and the incidence of complications related to highspeed digital imaging laryngoscopy, and to determine the incidence of inability of visualisation of the entire glottis during examination. Materials and methods: We prospectively collected data regarding the possible complications, incidence of the development of complications, as well as the incidence of exams on which the entire glottis was not visualised, of 113 examinees who were examined with high-speed digital imaging laryngoscopy with and without the usage of topical anaesthesia. Results: We observed seven complications (3.09% of laryngoscopies) in six patients (5.3% of examinees). All complications were mild and short-term without any long-term consequences. Inability of visualisation of the entire glottis was noted in three examinees (2.65%). Due to a severe gag reflex in seven examinees (6.19%) the entire larynx could not be visualised. In four of them (57.14%) after the application of topical anaesthesia we were able to visualise the entire glottis. Conclusion: Results of our study confirm efficiency and safety of hig speed digital imaging laryngoscopy with low incidence of mild complications and low inability of visualisation of the entire glottis during examination. Further researches are needed for the development of a precise algorithm which would optimise and standardise high-speed digital imaging, improve tolerance and facilitate examination.
