Objective: To evaluate the efficacy of a simple method to minimize gastric inflation in unprotected airways during resuscitation procedures. Methods: Ventilation of an airway simulator by use of a hose extended mask with leak and without leak and with or without additional oxygen (15 litres per minute). Experimental settings with artificial lung at a compliance = 300ml/ kPa and resistance = 0,5...

BACKGROUND The aim of this study was to analyze our experience with management of intrathoracic anastomotic leak after esophagectomy. METHODS Clinical data from 33 patients who developed intrathoracic anastomotic leak were evaluated retrospectively. These patients were selected from 1867 patients undergoing resection carcinoma of the esophagus and reconstruction between January 2003 and Decem...

BACKGROUND Results of studies to predict prolonged air leak (PAL; air leak longer than 5 days) after pulmonary lobectomy have been inconsistent and are of limited use. We developed a new scale representing the amount of early postoperative air leak and determined its correlation with air leak duration and its potential as a predictor of PAL. METHODS We grade postoperative air leak using a 5-g...

transcatheter aortic valve replacement (tavr) is a novel therapeutic intervention for the replacement of severely stenotic aortic valves in high-risk patients for standard surgical procedures. since the initial partner trial results, use of tavr has been on the rise each year. new delivery methods and different valves have been developed and modified in order to promote the minimally invasive p...

BACKGROUND Recently, endoscopic interventions (eg, esophageal stenting) have been successfully used for the management of intrathoracic leak. The purpose of this systematic review was to assess the safety and efficacy of techniques used in the management of intrathoracic anastomotic leak. DATA SOURCES We performed a systematic review of MEDLINE, EMBASE, and PubMed to identify eligible studies...

All manned spacecraft are vulnerable to leaks generated by micrometeorite or debris impacts. Methods for locating such leaks using leak-generated, structure-borne ultrasonic noise are discussed and demonstrated. Cross-correlations of ultrasonic noise waveforms from a leak into vacuum are used to find the location of the leak. Four methods for sensing and processing leak noise have been develope...

OBJECTIVE To determine pre-/intraoperative risk factors for anastomotic leak after colon resection for cancer and to create a practical instrument for predicting anastomotic leak risk. BACKGROUND Anastomotic leak is still the most dreaded complication in colorectal surgery. Many risk factors have been identified to date, but multicentric prospective studies on anastomotic leak after colon res...

AIM To investigate the contribution of fluorescein angiographic leaking microaneurysms (leak-MA) versus non-leaking microaneurysms (non-leak-MA) to retinal thickening in diabetic retinopathy. METHODS A consecutive series of 38 eyes from 24 patients with diabetic retinopathy was included. Leak-MA and non-leak-MA in each eye were selected in pairs at corresponding topographic location. Leaking ...

This paper will give an introduction to the leak detection of vacuum systems. Various methods to detect leaks as well as the most widely used helium leak detectors and their different applications are presented. Practical examples in the context of accelerator vacuum systems will illustrate the topic.
