Effect of High-Frequency Oscillations on Cough Peak Flows Generated by Mechanical In-Exsufflation in Medically Stable Subjects With Amyotrophic Later…
2016
BACKGROUND: Mechanically assisted coughing with mechanical in-exsufflation (MI-E) is recommended for noninvasive management of respiratory secretions in amyotrophic lateral sclerosis (ALS). To improve the effectiveness of the technique, a new device combining MI-E with high-frequency oscillations (HFO) has been developed. This work aimed to assess the effect of HFO on the cough peak flow generated by MI-E in medically stable subjects with ALS. METHODS: This was a prospective study that included subjects with ALS in a medically stable condition. Cough peak flow generated by MI-E was measured in 4 situations: without HFO, with HFO during insufflation, with HFO during exsufflation, and with HF…
Efficacy of Mechanical Insufflation-Exsufflation in Medically Stable Patients With Amyotrophic Lateral Sclerosis
2004
Objective: To determine under what circumstances the use of mechanical insufflation-exsufflation (MI-E) can generate clinically effective expiratory flows for airway clearance (> 2.7 L/s) for clinically stable patients with amyotrophic lateral sclerosis (ALS). Materials and method: Twenty-six consecutive patients with ALS were studied, 15 with severe bulbar dysfunction. Using a pneumotachograph and with the aid of an oronasal mask, we measured FVC, FEV1, peak cough flow (PCF), maximum insufflation capacity (MIC), PCF generated from a maximum insufflation MIC (PCFMIC), and PCF generated by MI-E (PCFMI-E). MI-E was delivered at 40 cm H2O. Maximum inspiratory pressure (PImax) and maximum expir…
Usefulness of Oscillations Added to Mechanical In-Exsufflation in Amyotrophic Lateral Sclerosis.
2019
BACKGROUND: Assisted coughing via mechanical in-exsufflation (MI-E) is a first-line treatment for secretion management in patients with amyotrophic lateral sclerosis (ALS) with unassisted CPF METHODS: We conducted a 12-month, prospective, randomized follow-up study of subjects with ALS for whom assisted coughing techniques were indicated. One group was treated with oscillations in addition to MI-E (MI-E+O), and the other group was treated with conventional MI-E. RESULTS: 29 subjects were included in the MI-E group and 27 subjects were included in the MI-E+O group. Five subjects (8.9%) required invasive techniques for secretion management (3 in the MI-E group and 2 in the MI-E+O group, P = .…
Predictors of need for noninvasive ventilation during respiratory tract infections in medically stable, non-ventilated subjects with amyotrophic late…
2014
BACKGROUND: Acute lower respiratory infections can impair muscle strength in patients with amyotrophic lateral sclerosis (ALS). When associated with an increase in load on the respiratory system, this situation may precipitate hypercapnic respiratory failure in non-ventilated patients with ALS. The aim of this study was to determine whether a clinical or functional parameter can predict the need for noninvasive ventilation (NIV) during an acute respiratory infection for medically stable, non-ventilated patients with ALS. METHODS: This was a prospective study involving all non-ventilated subjects with ALS admitted due to an acute respiratory infection to a respiratory care unit from a tertia…
Mechanical Insufflation-Exsufflation With Oscillations in Amyotrophic Lateral Sclerosis With Home Ventilation via Tracheostomy
2020
BACKGROUND: Mechanical insufflation-exsufflation (MI-E) applied via tracheostomy tubes in patients with amyotrophic lateral sclerosis (ALS) who are on home mechanical ventilation via tracheostomy is an effective procedure for respiratory secretion management. Nonetheless, tenacious secretions may remain and increase the risk of respiratory infections. The aim of this study was to determine whether adding oscillations to MI-E could reduce the rate of respiratory infections and the need for bronchoscopy to remove secretions in patients with ALS on home mechanical ventilation via tracheostomy. METHODS: This was a 2-y, prospective, crossover study. Subjects were treated with conventional MI-E a…
Er det sammenheng mellom oppvarmet CO2 gass, postoperative smerter og hypotermi ved laparaskopiske inngrep? : en kvantitativ undersøkelse
2016
Masteroppgave i spesialsykepleie – Universitetet i Agder 2016 Background: A common complication to laparoscopic procedures is postoperative shoulder pain. As a result of a surgical procedure, the patient is also exposed to hypothermia. There are various theories of the causes of postoperative shoulder pain and hypothermia. One of them suggest that the internal environment in the abdomen changes by insufflation of standard CO2 gas, and that this may result in peritoneal changes. Previous studies show that heated CO2 gas can reduce postoperative pain and hypothermia by laparoscopic surgery. Surgical and intensive patient is in a vulnerable situation, and the reflection on the operation and in…
OneShot-M: A New Device for Close Laparoscopy Pneumoperitoneum
2018
Introduction. The induction of pneumoperitoneum is the first and most critical phase of laparoscopy, due to the significant risk of serious vascular and visceral complications. The closed technique for the creation of pneumoperitoneum could lead to several surgical complications. The present study aimed to overcome the complications associated with the insertion of Veress needle, improving its use, and facilitating the rapid creation of pneumoperitoneum. Methods. Thirty large white female pigs were enrolled in our study. A common plunger was modified in order to allow the passage of a 15-cm long Veress needle. This method was applied to 26 laparoscopic procedures (26 pigs) of several speci…
