Condições de Assistência ao Recém-Nascido na Sala de Partos. Inquérito Nacional (2009)

Introdução: Desde 1989 que em Portugal as taxas de mortalidade materna, perinatal e neonatal apresentam uma diminuição significativa, em parte devido à rede perinatal implementada. Auditorias às condições existentes nos diferentes níveis de cuidados constituem um instrumento fundamental para identificar desvios da normalidade definida e podem ser um contributo para a melhoria de cuidados. Objectivos: Conhecer as condições e práticas de assistência nas salas de parto nacionais e, quando se justificar, propôr medidas de melhoria dos cuidados neonatais. Material e métodos: Foi enviado, por via electrónica, um questionário a 35 centros hospitalares com maternidade. O inquérito incluía questões relacionadas com os recursos humanos, equipamento disponível, características das salas de partos, práticas usadas na estabilização/ reanimação do recém-nascido, número de partos e número de recém-nascidos transferidos após o nascimento por ano, bem como questões relacionadas com a articulação com as equipas de obstetrícia. Resultados: Responderam 30 (86%) centros, 16 de apoio perinatal diferenciado. Oito (27%) centros têm pediatra presente em todos os partos, os restantes centros têm pediatra disponível para as situações de maior risco. Entre o material não disponível em alguns centros salienta-se o equipamento de monitorização cardio-respiratória, dispositivo de apoio ventilatório com pressão controlada, misturador de oxigénio, ventilador, CPAP (continuous positive airway pressure), incubadora de transporte e material para toracocentese e paracentese. Os critérios usados para oxigenoterapia e uso de surfactante “profiláctico” não são os mesmos entre os diversos centros. Todos os centros referiram a necessidade transferir recém-nascidos após o nascimento, quer por falta de diferenciação de cuidados quer por falta de vagas para internamento. Os centros de apoio perinatal referiram pior colaboração por parte das equipas de obstetrícia. Conclusâo: Os cuidados prestados ao recém-nascido nas salas de partos nacionais podem e devem ser melhorados. É necessário adequar o equipamento e recursos humanos às necessidades de cada centro. É necessário actualizar protocolos de práticas como oxigenoterapia e uso de surfactante “profiláctico”, reduzir o transporte após o nascimento e melhorar a comunicação com as equipas de obstetrícia.

Use of CPAP to Reduce Arterial Stiffness in Moderate-to-Severe Obstructive Sleep Apnoea, Without Excessive Daytime Sleepiness (STIFFSLEEP): an Observational Cohort Study Protocol

INTRODUCTION: Sleepiness is a cardinal symptom in obstructive sleep apnoea (OSA) but most patients have unspecific symptoms. Arterial stiffness, evaluated by pulse wave velocity (PWV), is related to atherosclerosis and cardiovascular (CV) risk. Arterial stiffness was reported to be higher in patients with OSA, improving after treatment with continuous positive airway pressure (CPAP). This study aims to assess whether the same effect occurs in patients with OSA and without sleepiness. METHODS AND ANALYSIS: This observational study assesses the CV effect of CPAP therapy on a cohort of patients with moderate-to-severe OSA; the effect on the subcohorts of sleepy and non-sleepy patients will be compared. A systematic and consecutive sample of patients advised CPAP therapy will be recruited from a single outpatient sleep clinic (Centro Hospitalar de Lisboa Central-CHLC, Portugal). Eligible patients are male, younger than 65 years, with confirmed moderate-to-severe OSA and apnoea-hypopnea index (AHI) above 15/hour. Other sleep disorders, diabetes or any CV disease other than hypertension are exclusion criteria. Clinical evaluation at baseline includes Epworth Sleepiness Scale (ESS), and sleepiness is defined as ESS above 10. OSA will be confirmed by polygraphic study (cardiorespiratory, level 3). Participants are advised to undertake an assessment of carotid-femoral PWV (cf-PWV) and 24 hours evaluation of ambulatory blood pressure monitoring (ABPM), at baseline and after 4 months of CPAP therapy. Compliance and effectiveness of CPAP will be assessed. The main outcome is the variation of cf-PWV over time.

Temporomandibular Joint Ankylosis in an Infant: A Rare Cause of Difficult Airway

1.Pre-assessment data of the patient A 2-year-old boy, weighing 15 kg was admitted with a history of limited mouth opening(inter-incisor distance of 6 mm), hypoplastic and retrognathic mandible (bird face deformity) and facial asymmetry from left temporomandibular joint ankylosis (TMJA). He was born at term, after an uneventful pregnancy, and there was no report of trauma during caesarean section. No other possible aetiologies were identified. He was scheduled for mandibular osteotomy. Preoperative ENT examination revealed adenotonsillar hypertrophy. 2. Anaesthetic Plan A fiberoptic nasal intubation was performed under deep inhalation anaesthesia with sevoflurane, with the patient breathing spontaneously. Midazolam (0.05 mg.kg-1) and alfentanil (0.03 mg.kg-1) were given and anaesthesia was maintained with O2/air and sevoflurane. No neuromuscular blocking agent was administered since the surgical team needed facial nerve monitoring. 3. Description of incident During surgery an accidental extubation occurred and an attempt was made to reintubate the trachea by direct laryngoscopy. Although the osteotomy was nearly completed, the vocal cords could not be visualized (Cormack-Lehane grade IV laryngoscopic view). 4. Solving the problem Re-intubation was finally accomplished with the flexible fiberscope and the procedure was concluded without any more incidents. Extubation was performed 24 hours postoperatively with the patient fully awake. After surgery mouth opening improved to inter-incisor gap of 15 mm. 5. Lessons learned and take home message Two airways issues present in this case can lead to difficultventilation and intubation: TMJA and adenotonsillar hypertrophy. These difficulties were anticipated and managed accordingly. The accidental extubation brought to our attention the fact that, even after surgical correction, this airway remains challenging. Even with intensive jaw stretchingexercises there is a high incidence of re-ankylosis, especially in younger patients. One should bear that in mind when anaesthetizing patients with TMJA.
