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.

Anaesthesia for total laryngectomy.
Because of the need to attend to the problem, there will be limited time for radiological imaging. For example, at one end of the spectrum almost all free-flap reconstructions are managed with temporary tracheostomy whereas elsewhere, overnight ventilation followed by extubation the following morning is the expected norm.
It is essential that anyone dealing with these situations must know what surgery has been performed and whether oral intubation is a feasible alternative. The anaesthetist will usually have information about the lesion e.
Anaesthesia for total laryngectomy.
J Laryngol Otol ; Suppl S2: Analgesic requirements tend to be less than for body cavity surgery, but this will not necessarily be the case in patients on moderate doses of opiates for pre-operative pain problems. Laryngeal cancer patients frequently have cardiac and respiratory co-morbidities with limited scope to optimize. Extrapolation of these concepts to patients with head and neck cancer undergoing major resections and free-flap surgery may help in improving outcomes.
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. High dependency and intensive care Many head and neck surgery patients will be looked after in enhanced care by virtue of their comorbidity, the length of surgical procedure or the need to closely monitor the free flap.
Trans-nasal high-flow rapid insufflation ventilatory exchange combines apnoeic oxygenation, continuous positive airway pressure and flow-dependent deadspace flushing and 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.
These programmes have been shown to improve outcomes in patients undergoing major colorectal and gynaecological procedures, by reducing length of stay and day morbidity.
Enhanced recovery in colorectal resections: Tracheostomy is an intervention with its own risks including inadvertent decannulation and is also associated with increased hospital stay. The resultant defect requires creation of a permanent tracheostomy tracheostome and repair of the pharynx. 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.
This article has been cited by other articles in PMC. Whether or not the patient presents as an emergency, there are two objectives. Free flaps 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 head and neck surgery: United Kingdom National Multidisciplinary Guidelines
Anticipated complications include bleeding, tube obstruction and accidental decannulation. Contractures resulting from the previous treatment are common in patients with head and neck cancer.
Care of the tracheostomy The Intensive Care Society has produced guidelines for the management of tracheostomy and temporary tracheostomy in particular. Colorectal Dis ; One must be aware that this group of patients are prone to sepsis and multi-organ failure needing intensive care support.
It is unusual forr any patient to be ventilated post-operatively. Formal tumour assessment for treatment planning examination under anesthesia and biopsy This is the more usual situation where the risk of airway obstruction is considered less likely.
Hypotensive conditions may minimise blood loss and haemodilution is practiced in some institutions with a view to improved blood flow in free flaps. Laryngectomy is performed in specialist centres and requires a team approach to airway management.
Many of these cases will prove to have a laryngeal tumour, in which case surgeons generally prefer that tracheostomy is avoided.
anaesthesi Managing the emergency stridulous patient. Airway considerations While patients presenting for head and neck surgery may have co-existent problems that could make airway management difficult e. 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 laryngecyomy apnoea time in head and neck patients including those with stridor to an average of 17 minutes.
Airway oedema can develop rapidly and is often precipitated by venous obstruction, posture change e.
