RESUMO
The EXIT (Ex utero intrapartum treatment) procedures have been, with a high degree of success, employed to treat a myriad types of fetal airway obstruction most commonly neck masses such as cystic hygroma and lymphangioma with ample plan including prenatal diagnosis by ultrasound scan or MRI. Before the advent of EXIT, formal documentations had been published with descriptions of intubation during intrapartum period and fetal airway protection either during normal or operative delivery. We report a 28-year-old gravida 2 para 1 who was referred to our Maternal Fetal Medicine (MFM) unit at 26 weeks and 3 days gestation with a foetal neck mass. We present a case of an successful EXIT procedure performed in the Lloyd Davies position with the hips abducted and flexed at 15 degrees as is employed during gynecologic laparoscopy surgery minus the Trendelenburg tilt. Both mother and baby are well. The benefits of this position are discussed.
RESUMO
Measurement of peak expiratory fow (PEF) by using the mini Wright meter is widely used for assessing patients with airway obstruction in the clinical practice. This document -written by the Pulmonary Function Commission of Chilean Respiratory Disease Society- provides a basic guideline for using this measurement in adult patients. Indications, technique and evaluation of the airway obstruction by measuring PEF through a mini Wrigth meter are briefy described.
La medición del fujo espiratorio máximo (FEM) con el mini-fujómetro de Wright se usa ampliamente en la práctica clínica para evaluar pacientes con obstrucción de las vías aéreas. Este documento redactado por la Comisión de Función Pulmonar de la Sociedad Chilena de Enfermedades Respiratorias, proporciona una guía práctica para efectuar esta medición en pacientes adultos. En este artículo se describen resumidamente las indicaciones, la técnica y la evaluación de la obstrucción de las vías aéreas a través de la medición del FEM con el mini-fujómetro de Wright.

Objetivos: mostrar los resultados de los primeros pacientes con síndrome de apnea obstructiva del sueño (SAOS) de tipo periférico esqueletal tratados en nuestro país con osteogénesis por distracción mandibular. Métodos: se trataron 9 pacientes con distracción osteogénica mandibular bilateral, con distractores marca Leibinger y Synthes. El periodo de latencia fue de 72 horas. La tasa de distracción mandibular, a razón de 1,0 mm cada 12 horas y la contención fue de 8 semanas. Luego se inició el tratamiento ortodóncico posquirúrgico. Se evaluaron los resultados a través de polisomnografía y estudios cefalométricos antes de la intervención, luego y al año del tratamiento. Resultados: el 89 por ciento de los casos fueron curados, el 11 por ciento tuvo mejoría. Dentro de las complicaciones encontradas, el 55 por ciento de los pacientes presentaron limitación temporal de la apertura bucal, que remitió con fisioterapia, y dos pacientes necesitaron traqueostomía con fines anestésicos. Conclusiones: la osteogénesis por distracción mandibular resultó ser un método terapéutico eficaz para el tratamiento del SAOS de tipo periférico, esqueletal(AU)
Objectives: to show the results from the first patients presenting with sleep obstructive apnea syndrome (SOAS) of skeletal peripheral type treated in our country with osteogenesis by mandibular distraction. Methods: Nine patients were treated with bilateral mandibular osteogenic distraction using Leibinger and Synthes distraction devices. Latency period was of 72 hours. Mandibular distraction rate at 1,0 mm each 12 hours and restraint was of 8 weeks. Then, postsurgical orthodontics treatment was started. Results were assessed by polysomnography and cephalometry studies before intervention, after it and at a year of treatment. Results: The 89 percent of cases had a good recovery, the 11 percent showed an improvement. Complications included: a temporary limitation of mouth opening in 55 percent disappearing with physiotherapy and two patients needed tracheostomy for anesthetic purposes. Conclusions: Osteogenesis by mandibular distraction was an effective therapeutical method for treatment of peripheral skeletal SOAS(AU)
