Assessment of Pulmonary Mechanics and Gastric Inflation Pressure During Mask Ventilation
1995
AbstractIntroduction:Mask ventilation is a procedure routinely used in emergency medicine. Potential hazards are inadequate alveolar ventilation and inflation of the stomach with air, leading to subsequent regurgitation and aspiration. The aim of this study was to measure lung function and gastric inflation pressures during mask ventilation.Methods:For this purpose, 31 patients scheduled for routine urological procedures were studied during induction of anesthesia. Lung function was assessed by recording respiratory flow and pressure directly at the face mask. Gastric inflation was observed with a microphone taped to the epigastric area.Results:Gastric inflation occurred in 22 of the 31 pat…
Respiratory Mechanics, Gastric Insufflation Pressure, and Air Leakage of the Laryngeal Mask Airway
1997
A potential risk of the laryngeal mask airway (LMA) is incomplete mask seal, which causes air leakage or insufflation of air into the stomach. The objective of the present study was to assess respiratory mechanics, quantify air leakage, and measure gastric air insufflation in patients ventilated via the LMA. Thirty patients were studied after induction of anesthesia but prior to any surgical manipulations. After the insertion of the LMA, patients were ventilated with increasing tidal volumes until one of the three following end points were reached: 1) gastric air insufflation, 2) airway pressure > 40 cm H2O, or 3) limitation of further increase in tidal volume by air leakage. The following …
Comparison of two different techniques of fibreoptic intubation
2009
BACKGROUND AND OBJECTIVE The application of analgesics and sedatives during fibreoptic intubation (FOI) may result in a transient decrease in arterial oxygen saturation.This study evaluates two different techniques of FOI and respective effects on procedural duration, arterial oxygen saturation, and coughing by the patient. METHODS Thirty-four patients received a standardized conscious sedation with fentanyl (1.5 microg kg(-1)) and midazolam (12.5 microg kg(-1)).All patients were randomly allocated to one of the following techniques: the 'vaporization' (VAP) technique included four applications of 2 ml lidocaine 2% administered through the working channel of the fibrescope supplying an oxyg…
Alternative Beatmungstechniken: IPPV, CPAP oder O 2 -Insufflation
2003
Tierexperimentelle Untersuchungen bieten Hinweise auf Vorteile von nichtphasischen Beatmungsstrategien gegenuber konventionellen Methoden.Diese Vorteile beziehen sich auf die geringere Traumatisierung der Lunge, die bessere Ventilation mit verbesserter Oxygenierung und CO2-Elimination sowie auf Vorteile in der systemischen und pulmonalen Hamodynamik.Noch besteht hinsichtlich alternativer Beatmungsstrategien wahrend der kardiopulmonalen Reanimation wie dem kontinuierlichen positiven Atemwegsdruck und der transtrachealen Sauerstoffinsufflation jedoch noch erheblicher Forschungsbedarf. Dabei kann in Zukunft die dynamische Computertomographie helfen, die Lungenbeluftung wahrend Reanimation darz…
Technique of transanal endoscopic microsurgery.
1988
Sessile adenomas are predominantly localized in the rectum and lower sigma. Surgical removal is indicated but often implies an invasive surgical procedure. Using conventional transanal surgical techniques, only the lower rectum can be reached and there are high rates of recurrence. The new technique combines an endoscopic view of the rectum under gas insufflation via a stereoscopic telescope with conventional surgical preparation and suturing. Adenomas can be excised using the mucosectomy technique or full-thickness-excision, whereas carcinomas should be excised using full-thickness excision with a sufficient border of healthy mucosa. In carcinomas of the sacral cavity, we remove the retror…
[Respiratory muscle aids during an episode of aspiration in a patient with Duchenne muscular dystrophy].
2005
We report the case of a Duchenne muscular dystrophy patient with good bulbar function but severely decreased forced vital capacity (9%) and spontaneous peak cough flow (PCF) (2.35 L/s). The patient needed continuous noninvasive ventilation (NIV) consisting of a volumetric ventilator with a nighttime nasal mask and a daytime mouthpiece. He also required application of manually assisted coughing techniques by insufflation with a resuscitation bag and chest thrust (manually assisted PCF after maximum insufflation capacity of 4.33 L/s). An episode of serious food aspiration was resolved by his main caregiver through NIV and manually assisted coughing. Bronchoscopy under sedation using NIV with …
Laryngeal Mask Airway Position and the Risk of Gastric Insufflation
1998
A potential risk of the laryngeal mask airway (LMA) is an incomplete mask seal causing gastric insufflation or oropharyngeal air leakage.The objective of the present study was to assess the incidence of LMA malpositions by fiberoptic laryngoscopy, and to determine their influence on gastric insufflation and oropharyngeal air leakage. One hundred eight patients were studied after the induction of anesthesia, before any surgical manipulations. After clinically satisfactory LMA placement, tidal volumes were increased stepwise until air entered the stomach, airway pressure exceeded 40 cm H2 O, or air leakage from the mask seal prevented further increases in tidal volume. LMA position in relatio…
Mechanical insufflation-exsufflation vs. tracheal suctioning via tracheostomy tubes for patients with amyotrophic lateral sclerosis: a pilot study.
2003
To compare the effects of mechanical insufflation-exsufflation vs. suctioning via tracheostomy tubes on respiratory variables for six amyotrophic lateral sclerosis patients.In this prospective crossover study, six consecutive patients with amyotrophic lateral sclerosis who required continuous mechanical ventilation via tracheostomy tubes and developed chest infections underwent measurement of pulse oxyhemoglobin saturation (SpO2), peak inspiratory pressure (PIP), mean airway pressure (Pawm), and work of breathing performed by the ventilator (WOBv) at baseline and 5 and 30 min after tracheal suctioning and 5 min after mechanical insufflation-exsufflation.The baseline values were 93.50 +/- 2.…
Prospective comparison of cardiopulmonary events during minilaparoscopy and colonoscopy under conscious sedation.
2005
BACKGROUND AND STUDY AIMS Cardiorespiratory parameters were examined throughout diagnostic minilaparoscopy procedures. The same parameters were analyzed during colonoscopy, and the data were compared. PATIENTS AND METHODS Sixty-five consecutive unselected patients undergoing minilaparoscopy (group 1: ASA I, n = 34; group 2: ASA II/III, n = 31) and 61 consecutive unselected patients undergoing colonoscopy (group 3: ASA I, n = 31; group 4: ASA II/III, n = 30) were included. Oxygen saturation (Sao (2)), heart rate (HR) and mean arterial pressure (RRm) were measured continuously, and 12-lead electrocardiography (ECG) recordings were made at specific times during each procedure. RESULTS Minor di…

Patients and methods. A total number of 35 patients with neurological deficits, like cerebrovascular accident (CVA), trigeminal neuralgia, post herpetic neuralgia, meningitis, cervical myelopathy, demyelinating disease, acoustic neuroma, muscular neuropathy and parkinsonism were treated with ozone therapy in our institution. Results. Group 1) Hemorrhagic - 6 patients Group 2) Ischemic - 29 Patients Both the groups showed improvement varying from 20% to 100%: • Hemorrhagic patients took more time for improvement as compare to ischemic group. • Hemorrhagic patients showed partial recovery. • Ischemic group showed almost 90% - 100% recovery. Patients who received ozone therapy after 12 months …
