Simultaneous recordings of oesophageal acid exposure with conventional pH monitoring and a wireless system (Bravo).
OBJECTIVES Oesophageal pH monitoring is a useful test for the diagnosis of gastro-oesophageal reflux disease (GORD) but has some limitations related to the nasopharyngeal electrode. Recently, a telemetric catheter free system (CFS) (Bravo; Medtronic) was developed. The aim of this study was to determine the concordance of data between the conventional pH measurement system (CPHMS) and the CFS B...
متن کامل[Outpatient monitoring of oesophageal pH with a catheter-free pH-meter (Bravo System). A Study of tolerance, safety and efficacy].
BACKGROUND AND OBJECTIVE A new catheter-free outpatient oesophageal pH-meter system (Bravo) has recently been developed. The objective of this study is to test the tolerance, safety and efficacy of the system in the measurement of gastric-oesophageal reflux by comparing it with a conventional pH system. PATIENTS AND METHOD The study was performed on a control group consisting of 10 healthy vo...
متن کاملEffect of Propofol on Acid Reflux Measured with the Bravo pH Monitoring System
Background/Aim. The aim of this study was to determine the effect of propofol on acid reflux as measured with the Bravo pH monitoring system. Methods. 48-hour pH tracings of 88 children were retrospectively evaluated after placement of the Bravo capsule under propofol. Comparisons between day 1 and day 2, as well as 6-hour corresponding segments from day 1 and day 2, were made. Results. The num...
متن کاملSimultaneous tracheal and oesophageal pH monitoring during mechanical ventilation.
OBJECTIVE To simultaneously record tracheal and oesophageal pH in mechanically ventilated children to determine: (1) the feasibility and safety of the method; (2) the incidence of gastro-oesophageal reflux (GOR) and pulmonary contamination; and (3) their associated risk factors. DESIGN Prospective study. SETTING Paediatric intensive care unit in a university hospital. PATIENTS Twenty mech...
متن کاملGastro-oesophageal reflux — initial experience with a radiotelemetry system for prolonged oesophageal pH monitoring
A radiotelemetry system has been used to monitor gastro-oesophageal reflux over a prolonged period in 27 asymptomatic control subjects and in 15 patients with reflux symptoms. In control subjects, the frequency of reflux episodes (pH < 5) ranged from 0.1 - 0.7 per hour of recording (median 0.36) by day, and from 0 - 1.0 per hour (median 0.12) by night. The duration of reflux (pH < 5) per hour o...
