CASE 1: DAVID
19 yrs old boy with Duchenne Muscular Dystrophy (DMD)
presenting with recurrent episodes of nocturnal
desaturation and hypercapnia
Personal History
• Diagnosis at 3 yrs of age, loss of deambulation at 11 yrs
• Progressive difficult oral feeding (difficulty finishing a full meal),
weight loss gastrostomy (2012)
• On-going problems: severe scoliosis, osteoporosis, dilated
cardiomyopathy, depression
• A nocturnal non-invasive ventilation (NIV) therapy was
discussed in a different hospital since 2011 but never started
Clinical presentation at visit
• Fair general conditions, severe scoliosis, normal chest auscultation
• ABG: pH 7.38, paCO2 46.5, paO2 36.2
• LFT: VC 0.27 L (6%), PCF 42.6 L/m
DMD
• is a recessive X-linked form of muscolar dystrophy, affecting around 1 in
3,600 boys, which results in muscle degeneration and eventual death
• caused by a mutation in the dystrophin gene, the largest gene located on the
human X chromosome, which codes for the protein dystrophin
Main symptoms:
- awkward manner of walking, stepping, or running, frequent falls, fatigue,
increased lumbar lordosis
- eventual loss of ability to walk (usually by the age of 12)
- skeletal deformities (including scoliosis)
- respiratory problems (hypoxemia, hypercapnia)
- higher risk of neurobehavioral disorders, learning disorders (dyslexia)
IMPACT OF NASAL VENTILATION ON SURVIVALIN HYPERCAPNIC DMD
Thorax 1998:53:949-52
Arterial Po2 and Pco2 by the time of
discharge improved significantly on NIPPV
These improvements were sustained over time
In conclusion: nasal ventilation is likely to increase survival in
hypercapnic patients with DMD and should be considered as a
treatment option when ventilatory failure develops

Preoperative training in and postoperative use of manual and assisted cough techniquesare necessary:- baseline peak cough flow is below 270 L/min- baseline maximum expiratory pressure is below 60 cmH2O
Preoperative training in and postoperative use of non-invasive ventilation is:- strongly recommended for patients with a baseline FVC < 50% predicted- necessary with a FVC < 30% predicted.

CASE 2: ARIANNA, 12 months old, F, SMA1
12 months old infant with type 1 spinal muscular atrophy presenting with
recurrent episodes of desaturation
Personal History
At the age of 2 months onset of progressive hypotonia, muscle weakness and delayed motor
development
At the age of 4 months diagnosis of Spinal Muscular Atrophy (SMA) confirmed with a DNA
blood test.
At the age of 5 months insertion of percutaneous endoscopic gastrostomy (PEG) under
local anaesthesia (progressive difficulty in oral feeding - finishing a full meal, weight loss)
SPINAL MUSCULAR ATROPHY (SMA)
Spinal cord motor neurons disease resulting in progressive muscular atropy and
weakness. (1:6.000 – 1:10.000)
Recessive autosomic inherited disease: 1/ 50 is a healthy carrier of the gene

Respiratory managementMonitoring cardio respiratory parameters, airway

SMA 1
R. Cutrera 2016 - cutrera@opbg.net
Treatment Options suggested to parents of children with SMA type 1
1. Let the Nature “take its course”: Home
discharge without mechanical ventilation but
with support for feeding and treatment for pain
and dyspnoea and education to prevent and
treat acute respiratory deterioration + MI-E
2. Home discharge with 1 + low span mechanical
IPPV + MI-E
3. Home discharge with 1 +High span IPPV MI-E
4. Tracheal ventilation

A retrospective chart review of 194 SMA 1 (103 males, 91 females) patients’ outcomes has been carried out:
1. letting nature take its course (NT) 121 (62.3%),
2. tracheostomy and invasive mechanical ventilation (TV) 42 (21.7%)

• Should be preferred a transparent model that allows the inspection of the nostrils and ensure that they are not partially or completely occluded by secretions or dislocations of the mask.
• The smaller the child is, the higher the risk is, as the size of his face fell, and even a slight displacement of the mask can interfere with the proper delivery of positive pressure to the airway.
• The masks should be positioned in order to determine the lowest possible pressure on
the skin that is compatible with an effective ventilation.
