A premature male infant was born at 30 weeks' gestation with a birth weight of 1,700 g in a rural hospital. He was diagnosed with respiratory distress syndrome and received continuous positive airway pressure treatment for 26 days. At 26 days after birth, the patient was transferred to our hospital for further evaluation and management. A comprehensive eye examination revealed a stage 3 retinopathy of prematurity (ROP) involving zone 2 in both eyes. The patient was recommended to a provincial-level eye hospital for emergency laser therapy...

BACKGROUND: Obstructive sleep apnea (OSA) is an increasingly prevalent clinical problem with significant effects on quality of life and cardiovascular risk. Surgical therapy represents an important treatment for those unable to use positive airway pressure. This systematic review examines the available cardiovascular risk reduction data for surgical treatment of OSA. METHODS: A comprehensive literature search was performed. Articles were included if they met the following criteria: (1) adults >18 years (2) OSA diagnosed by sleep study; (3) surgical intervention performed for OSA; (4) one or more physical or biochemical cardiovascular and/or cerebrovascular variables was measured pre-operatively and at ≥14 days postoperatively...

OBJECTIVE: The majority of adults sleep with a partner, making sleep a dyadic experience. However, interventions to improve sleep have primarily focused on individuals. This qualitative analysis used a dyadic approach to identify facilitators and barriers to successful treatment of one of the most common sleep disorders, obstructive sleep apnea, with continuous positive airway pressure (CPAP). METHODS: Twenty joint qualitative interviews were conducted with couples, one couple at a time, with a sample of 20 patients with obstructive sleep apnea and their partners to develop an understanding of couples' experiences with CPAP use...

BACKGROUND: Most preterm infants born at 29-32 weeks gestation now avoid intubation in early life, and thus lack the usual conduit through which exogenous surfactant is given if needed. OBJECTIVE: The aim of this work was to examine whether a technique of minimally invasive surfactant therapy used selectively at 29-32 weeks gestation would improve outcomes. METHODS: We studied the impact of selective administration of surfactant (poractant alfa 100-200 mg/kg) by thin catheter in infants with respiratory distress syndrome on continuous positive airway pressure (CPAP)...

Nasal obstruction is known to cause resistance to continuous positive airway pressure (CPAP) therapy in obstructive sleep apnea syndrome (OSAS). In this paper, short- and long-term nasal congestion in OSAS patients receiving CPAP treatment were evaluated with acoustic rhinometry (AR). A total of 36 patients with moderate-to-severe OSAS, diagnosed with polysomnography were included in the study. Ten healthy subjects without OSAS constituted the control group. Pre-treatment nasal patency were measured with AR in all participants...

BACKGROUND: Myasthenia gravis (MG) is an uncommon autoimmune disorder affecting the neuromuscular junction and manifesting as muscle weakness. A multitude of stressors can exacerbate MG. When symptoms are exacerbated, muscle weakness can be severe enough to result in respiratory failure, a condition known as myasthenic crisis (MC). OBJECTIVE: This review discusses risk factors, diagnosis, management, and iatrogenic avoidance of MC. DISCUSSION: MC can affect any age, ethnicity, or sex and can be precipitated with any stressor, infection being the most common...

Nasal injuries with use of nasal continuous positive airway pressure (CPAP) range from blanching of nasal tip to septal necrosis and septal drop. This analysis was done in preterm neonates of < 34-week gestation, who received nasal CPAP as primary support as part of a randomized trial comparing Jet device with Bubble device for delivery of CPAP, both through nasal prongs of different structure, make and fixation methods. Nasal injury was assessed using a validated nasal injury score. Out of 170 neonates enrolled, 103 (61%) had nasal injuries; moderate and severe injuries were observed in 18 (11%) and 8 (5%) infants, respectively...

OBJECTIVES: To systematically assess barriers delaying home respiratory equipment requisition and to evaluate for temporal correlation between delays and emergency room or hospitalization episodes. BACKGROUND: Initiation of home respiratory treatments is delayed because of delays in delivery of durable medical equipment (DME). This study assesses root causes of such delays from a system perspective. We also describe clinical consequences by measuring emergency room visits and hospitalization days for temporal correlations...

BACKGROUND AND OBJECTIVES: There is a high prevalence of undiagnosed obstructive sleep apnoea (OSA) in obese surgical patients. We investigated the extent to which anthropometric measurements can be used to identify the presence of significant OSA (Apnoea/Hypopnoea Index (AHI) ≥ 20) in adult patients. MATERIALS AND METHODS: We prospectively studied 1357 adult patients scheduled for elective laparoscopic bariatric surgery. Prior to surgery, body mass index (BMI), gender, neck circumference, STOP-Bang score, SpO2, neck and trunk fat (by dual X-ray absorptiometry) were recorded...

OBJECTIVE: Mortality rates from birth asphyxia in low-income countries remain high. Face mask ventilation (FMV) performed by midwives is the usual method of resuscitating neonates in such settings but may not always be effective. The i-gel is a cuffless laryngeal mask airway (LMA) that could enhance neonatal resuscitation performance. We aimed to compare LMA and face mask (FM) during neonatal resuscitation in a low-resource setting. SETTING: Mulago National Referral Hospital, Kampala, Uganda...

Nasal High Flow (HF) is a mode of 'non-invasive' respiratory support for preterm infants, with several potential modes of action, including generation of distending airway pressure, washout of the nasopharyngeal dead space, reduction of work of breathing, and heating and humidification of inspired gas. HF has several potential advantages over continuous positive airway pressure (CPAP), the most commonly applied form of non-invasive support, such as reduced nasal trauma, ease of use, and infant comfort, which has led to its rapid adoption into neonatal care...

Obstructive sleep apnea syndrome (OSAS) is known to be a risk factor for atherosclerosis (AS), derived from a series of chronic inflammatory reactions caused by hypoxia. However, the association between chronic inflammation and high blood pressure caused by hypoxia remains to be fully elucidated. The aim of the present study was to investigate the effect of continuous positive airway pressure (CPAP) therapy on inflammatory cytokines and AS. A total of 100 patients with OSAS and 50 healthy control subjects were enrolled...

Continuous positive airway pressure (CPAP) is the standard treatment for moderate-to-severe obstructive sleep apnoea (OSA). However, adherence to CPAP is limited and non-CPAP therapies are frequently explored. Oral appliance (OA) therapy is currently widely used for the treatment of snoring, mild, moderate and severe OSA. The most commonly used and studied OA consists of a maxillary and mandibular splint which hold the lower jaw forward during sleep. The efficacy of OA is inferior to CPAP; however, the effectiveness as measured by sleepiness, quality of life, endothelial function and blood pressure is similar likely due to higher acceptance and subjective adherence...

OBJECTIVES: Polysomnography (PSG) is the gold standard for the scoring of residual respiratory events during continuous positive airway pressure (CPAP). Studies comparing PSG scoring with automatic scoring by the built-in software of CPAP devices have reported acceptable agreements except for the hypopnea index (HI) in adult patients, but no study has yet been conducted in children. The aim of the present study was to compare the automatic scoring by CPAP device and manual scoring using the software tracings of the CPAP device integrating pulse oximetry (SpO2) with in-lab polygraphy (PG)...
