Special Considerations in Anesthesia for Laryngeal Cancer Surgery .. Supraglottic laryngectomy offers the advantage of cure with preservation of speech for. Therefore tracheotomy was standard part of laryngectomy (usually under local anesthesia) to establish airway with general anesthesia. The anaesthetic considerations for head and neck cancer surgery are . this is physically impossible (e.g. the post-laryngectomy patient) or because oral.

General anaesthetic considerations World Health Organization WHO checklist All theatre staff are recommended to participate laryngecotmy this initiative to ensure that teams work effectively and that the right patients get the right surgical procedure they have consented to.
Trans-nasal high-flow rapid insufflation ventilatory exchange combines apnoeic oxygenation, continuous positive airway pressure and flow-dependent deadspace flushing dor has the potential to change the nature of difficult intubations from a hurried stop—start process to a more controlled event, with an extended apnoeic window and reduced iatrogenic trauma. Perioperative management of the elective laryngectomy. Care of the tracheostomy The Intensive Care Society has produced guidelines for the management of tracheostomy and temporary tracheostomy in particular.
Laryngeal cancer patients frequently have cardiac and respiratory co-morbidities with limited scope to optimize. N Engl J Med ; A guaranteed airway from pre-operative ward care through to safe discharge must be considered as an essential duty of care for any institution undertaking surgery of this nature. This is the official guideline endorsed by the specialty associations involved in the care of head and neck cancer patients in the UK.
This is the more usual situation where the risk of airway obstruction is considered less likely. Removal for tracheal tubes is the responsibility of the anaesthetist. Early return to theatre, however, in the event of compromise, may allow the flap to be salvaged if the blood flow can be restored. Maintenance of oxygenation is fundamental to airway management and techniques that extend the apnoeic window allow more controlled, less hurried and more careful, gentle instrumentation.
This sort of haemorrhage can arise suddenly and with little warning. Cardiac output monitoring to guide fluid replacement in head and neck microvascular free flap surgery — what is current practice in the UK?
Trans-nasal high-flow rapid insufflation ventilatory exchange or THRIVE delivered through a nasal high-flow oxygen delivery system has recently been shown to increase the apnoea time in head and neck patients including those with stridor to an average of 17 minutes.
The resultant defect requires creation of a permanent tracheostomy tracheostome and repair of the pharynx. Laser surgery The risk of airway fires due to laser is low provided careful precautions including laser safe tubes are used.
Patients with pharyngolaryngeal tumours frequently larynhectomy residual food debris at laryngoscopy which abaesthesia interfere with the view obtained especially for instruments with a limited field of vision. Acute presentations with stridor require a collaborative approach to the airway that only rarely involves awake fibre-optic intubation. Airway considerations While patients presenting for head and neck surgery may have co-existent problems that could make airway management anaesthfsia e.
Firstly a biopsy will be taken for tissue diagnosis and secondly the tumour bulk will be reduced so as to minimise any likelihood of obstruction. Abstract This is the official guideline endorsed by the specialty associations involved in the care of head and neck cancer patients in the UK. Whether or not the patient presents as an emergency, there are two objectives. J Laryngol Otol ; Suppl S2: Prophylaxis for thromboembolism is discussed elsewhere in these guidelines 1.
Anaesthesia for total laryngectomy.
If a patient is already at risk of airway obstruction due to tumour bulk, then it is probable that they will be at greater risk following induction laryngetomy anaesthesia, whether intravenous or inhalational. The Royal College of Anaesthetists, Extrapolation of these concepts to patients with head and neck cancer undergoing major resections and free-flap surgery may help in improving outcomes.
Relevant pre-operative measures might include carbohydrate loading with carbohydrate drinks 1—2 days before surgery. Management of a anxesthesia patient for other procedures. These programmes have been shown to improve outcomes in patients undergoing major colorectal and gynaecological procedures, by reducing length of stay and day morbidity.
Neck haematoma, flap failures, fistulas and airway management issues e.
Anaesthesia for head and neck surgery: United Kingdom National Multidisciplinary Guidelines
Many of these cases will prove to have a laryngeal tumour, in which case surgeons generally prefer that anaestbesia is avoided. Total laryngectomy is the en bloc removal of the laryngeal structures including the epiglottis, hyoid, and a variable amount of upper trachea. Heliox mixtures may provide symptomatic relief, while further information is obtained, e. There are differences as to which patients warrant this level of airway protection and even as to suitability for delivery of such care by immediate return to the ward vs high dependency or intensive care.
Many resections and free tissue transfers will not be associated with significant bleeding, though this is not necessarily true for tongue and mandibular resections where brisk bleeding may occur. These alternatives tend to become more of a problem if the operative procedure is prolonged. Hypotensive conditions may minimise blood loss and haemodilution is practiced in some institutions with a view to improved blood flow in free flaps.
Colorectal Dis ; Induction of anaesthesia If a patient is already at risk of airway obstruction due to tumour bulk, then it is probable that they will be at greater risk following induction of anaesthesia, whether intravenous or inhalational.
Comorbidity and pre-operative assessment are considered elsewhere in the guidelines. Attempts have been made to increase the success of free-flap anastomoses by medical means but there is no general consensus as to what if anything is efficacious.
Anaesthesia for patients with laryngeal larynhectomy.
Specific operative considerations The compromised airway In the patient who presents with acute airway compromise the obvious option is to consider a tracheostomy under local anaesthesia.
