Pharyngolaryngeale Beschwerden nach Allgemeinanästhesien

Abstract

Laryngeal and pharyngeal complaints are among the subjective problems most frequently reported by patients after general anaesthesia involving endotracheal intubation, others being pain, nausea and vomiting. Hoarseness, sore throat, and vocal cord injuries restrict patients' social lives, and in some cases also their working lives. The most frequent types of laryngeal injury are swollen mucosa and haematoma of the vocal cords. Vocal cord paralysis occurs much less frequently. Knowledge of the pathophysiological aspects and other relevant factors associated with laryngopharyngeal morbidity are essential cornerstones of quality assurance in perioperative respiratory tract management. In this review specific sections are devoted to the implications of anaesthesia involving endotracheal intubation and laryngeal masks for laryngopharyngeal morbidity, and also particular aspects of thyroid gland surgery, cardiothoracic and bariatric surgery and obstetric and paediatric anaesthesia, and medicolegal aspects.

Voice Condition Following Short-Term Endotracheal Intubation in Head and Neck Surgery: Study Protocol for Clinical Trial

“…According to the literature, appearance of hoarseness after short-term endotracheal intubation can occur in 14.4% to 50% of patients ( 1 , 16 , 17 ). These data refer to short-term endotracheal intubation regardless of the type of surgery and part of the human body that was operated on ( 18 ).…”

The Effect of Adjustment of Endotracheal Tube Cuff Pressure during Scarless Remote Access Endoscopic and Robotic Thyroidectomy on Laryngo-Pharyngeal Complications: Prospective Randomized and Controlled Trial

“…Laryngo-pharyngeal complications, such as POST, hoarseness, dysphagia, and cough, may occur after general anesthesia [14], but it is worth nothing that these laryngo-pharyngeal complications develop in most patients after thyroidectomy [7]. Since these complications are mainly associated with endotracheal intubation and cuff pressure, the cuff pressure of the endotracheal tube is monitored continuously in patients with open thyroidectomy [8].…”

Voice and Vocal Fold Condition Following Short-Term General Anesthesia: A Prospective Study

“…Laryngeal complaints are common among patients following endotracheal intubation with an incidence of dysphonia varying between 14.4% and 50%. 1,2 Even more severe findings such as glottic hematoma, laceration, and subluxation of the cricoarytenoid joint have been reported (up to 6.2%). 3 Although dysphonia is reported less frequently following a supraglottic airway (SGA), injuries, such as cricoarytenoid subluxation and recurrent laryngeal nerve palsy have been reported.…”

“…3 Although dysphonia is reported less frequently following a supraglottic airway (SGA), injuries, such as cricoarytenoid subluxation and recurrent laryngeal nerve palsy have been reported. 1,4,5 Postoperative dysphonia affects social and professional performance. 6−8 In the American Society of Anesthesiologists Closed Claims Project database 1990−2007, 7% of the 5230 claims were related to airway injury, of which 33% were of laryngeal nature.…”

“…9,10 Risk factors for laryngeal complaints after anesthesia include size of the endotracheal tube (ETT), use of an introducer or neuromuscular (NM) blocking agents, intubation and extubation conditions, type and duration of surgery, and demographic factors. 1,2,5,11,12 Compared with the consequences of prolonged intubation, sufficient knowledge of laryngeal changes following shortterm airway instrumentation is currently lacking. 6,13−16 A previous systematic review showed that dysphonia and laryngeal injuries are common findings following short-term general anesthesia.…”
