Endotracheal intubation is an airway management procedure commonly performed under general anesthesia. It is linked with postoperative voice changes. The incidence and reasons of hoarseness and vocal cord injury are not very well investigated, especially after short-term anesthesia and intubation in head and neck surgery. The aim of the study is to identify the causes of voice changes after short endotracheal anesthesia in head and neck surgery. The study will include patients scheduled for head and neck surgery under general anesthesia with endotracheal intubation up to 3 hours. There will be 3 groups of patients, as follows: thyroid surgery, non-thyroid surgery, and control group undergoing surgery outside head and neck. Videostroboscopy will be recorded before and after surgery. Further diagnostic workup will include voice status; subjective voice self-analysis; perceptive and objective acoustic voice analysis at 4 time points (preoperatively, postoperative day 2, 2 weeks and 1 month after surgery). Endotracheal intubation is a safe method of airway management although it can temporarily alter a patient's voice quality. It is not known how much of this is the result of anesthesia, general condition of the patient, or surgery. This trial is expected to shed some light on this issue. Key words: Endotracheal intubation; General anesthesia; Head and neck surgery; Voice changes Endotrahealna intubacija je dio rutinskog anestezioloskog postupka tijekom opce anestezije kojoj su svakodnevno podvrgnuti brojni bolesnici. Povezana je s poslijeoperacijskim promjenama glasa. Incidencija i tocni razlozi promuklosti i ozljeda glasnica, pogotovo nakon kratkotrajnih anestezija i intubacija, jos uvijek nisu razjasnjeni. Cilj ove studije je pronaci uzroke promjena glasa nakon kratke endotrahealne anestezije u operacijama glave i vrata. Ova prospektivna kohortna studija ce ukljuciti bolesnike predvidene za operacije u podrucju glave i vrata u opcoj endotrahealnoj anesteziji do 3 sata. Predvidene su 3 skupine bolesnika: operacija stitnjace, operacija u podrucju glave i vrata te kontrolna skupina s operacijom izvan ove regije. Svim ukljucenim bolesnicima snimit ce se videostroboskopija prije i nakon operacije. Slijedi obrada glasa koja ce ukljuciti glasovni status; subjektivnu samoprocjenu glasa; perceptivnu i objektivnu akusticku analizu glasa u 4 vremenske tocke: prije operacije, 2. poslijeoperacijski dan, 14. poslijeoperacijski dan i mjesec nakon operacije. Endotrahealna intubacija je sigurna metoda zbrinjavanja disnog puta, iako dovodi do kratkotrajne promjene kvalitete glasa bolesnika. Koliko su one posljedica iskljucivo utjecaja anestezije, opceg stanja bolesnika, a koliko samog operativnog zahvata nije poznato. Rezultati ove studije bi mogli ovo razjasniti. Kljucne rijeci: Endotrahealna intubacija; Opca anestezija; Kirurgija glave i vrata; Promjena glasa
Introduction Disorders of phonation, swallowing and breathing are possible as a result of endotracheal intubation, regardless of the type of the surgery performed. These disorders are usually caused by injuries [...]
