OBJECTIVE To assess the outcome of a policy of emergency coronary angiography with or without rescue angioplasty in patients with acute myocardial infarction and ECG evidence of failed reperfusion after thrombolysis. DESIGN A cohort study. SETTING Regional cardiothoracic unit. PATIENTS 197 patients with acute myocardial infarction fulfilling a simple ECG criterion of failed reperfusion. ...

Objectives:The aim of the present study was to assess the analgesic efficacy of IV ketamine injection inaddition to nephrostomy tract infiltration of ketamine – bupivacaine on postoperative pain relief after tubeless percutaneous nephrolithotomy (PCNL). Patients and Methods: Patients (n = 100), with renal stone who were candidates for PCNL were randomized to five groups with 20 cases in each: G...

This paper describes MRESim, a multi-robot exploration simulator which aims to provide a middle ground between the RoboCup Agent and Virtual Robot competitions. A detailed description of this new infrastructure is provided, followed by examples and case studies of successful research outcomes arising from the use of MRESim. Our work on MRESim won the 2014 Infrastructure competition of the RoboC...

In natural disaster, quick rescue is required. However, quick rescue is very difficult because victims are most likely to be left at the place where the rescue team are hard to find, such as under debris of broken house. The necessity for the rescue robot, which assists the rescue team by searching and finding victims of a disaster, is increasing. Nowadays many researchers and facilities are fo...

The summary consists of six sections: 1. Executive summary 2. Importance of location information: lessons learned from three recent rescue operations 3. Why conventional wireless techniques are difficult for underground mines? 4. Potential pitfalls of unconventional wireless techniques 5. Advantages of the microseismic technique 6. Future work on microseismic based trapped miner location technique

Results Findings revealed six themes: Knowticing; Getting a doctor; Trans‐action; Taleoring care; Experiencing vulnerability and Transporting: facilitating comfort and control. Three narrative aspects representing advanced practice were described: Rescue; Recognition and Responsibility; and Respect. The stories were of complex care situations relating to diverse areas of work highlighting criti...

Researchers from the National Institute for Occupational Safety and Health (NIOSH), in cooperation with mine operators, conducted a study of heat-stress exposures among mine rescue workers in underground mines. Mine rescue workers face extreme heat loads as they enter hot and poorly ventilated environments, particularly when they are wearing breathing apparatus. The burden of wearing a closed-c...
