From: Recommendations for the management of MPS IVA: systematic evidence- and consensus-based guidance
Statement | Percentage consensus |
---|---|
Pre-, intra- and post-operative care (until extubation is complete) for all procedures requiring general anaesthesia, conscious or deep sedation, should be supervised by an anaesthetist with experience in treating patients with MPS and/or complex airway management. In addition, the anaesthetist should have access to Intensive Care support and be surrounded by an experienced team capable of performing emergency tracheotomy if required Evidence Grade: C (consistent level 4 studies) | 98% |
A full assessment of the risks and benefits should take place with the patient and family prior to any procedure. All pre-operative information should be made available to allow decision making Evidence Grade: C (consistent level 4 studies) | 100% |
ENT respiratory, cardiac, and radiological assessment should be performed prior to any procedure requiring anaesthesia Evidence Grade: C (consistent level 4 studies) | 93% |
It is critical to maintain a neutral neck position during all surgeries, and during intubation and extubation to avoid paralysisa. Strongly recommend the use of techniques that allow maintenance of the neutral neck position, including use of laryngeal mask airway (LMA) for shorter procedures, or intubation with a video laryngoscope or fibreoptic intubation Evidence Grade: C (consistent level 4 studies) | 87% |
Pre-operative and intra-operative measures to avoid hypotension should be adopted during all surgical procedures in patients with MPS IVA to maintain spinal cord perfusion and therefore protect spinal cord function Evidence Grade: D (limited published evidence) | 98% |
Intra-operative neurophysiological monitoring (including somatosensory evoked potential [SSEP], electromyography [EMG] and motor evoked potentials [MEP]) is strongly recommended during all spinal surgeries and other potentially lengthy or complicated procedures, including those that require manipulation of the head and neck Evidence Grade: D (limited published evidence) | 94% |
For other surgeries and procedures, neurophysiologic monitoring should be considered based on pre-existing risk for spinal cord compression and instability, need for spine manipulation, possibility of hemodynamic changes and blood loss, or extended length of time Evidence Grade: D (limited published evidence) | 94% |
Intrathecal and epidural techniques are high-risk in patients with MPS IVA and should be avoided wherever possible Evidence Grade: D (limited published evidence) | 83% |
