Objective: To assess the occupational hazard of unscavenged waste anesthetic gases on reproductive health (infertility, abortions, preterm delivery and congenital anomalies) in personnel working in operating rooms. Methods: The study was conducted by a questionnaire-based survey of 99 operating room personnel and 118 non exposed personnel from the general wards in Omdurman Military Hospital, Om...

Anaerobic digestion of dairy cow manure (CM), the organic fraction of municipal solid waste (OFMSW), and cotton gin waste (CGW) was investigated with a two-phase pilot-scale anaerobic digestion (AD) system. The OFMSW and CM were digested as single wastes and as combined wastes. The single waste digestion of CM resulted in 62m3 methane/ton of CM on dry weight basis. The single waste digestion of...

Green waste is a key component of California’s solid waste stream and so is an important target for effective waste diversion. The California Integrated Waste Management Board (CIWMB) reports that about 15 million cubic yards of organics comprised largely of green waste are diverted annually in California. The diverted organics are principally used as compost and mulch in agricultural and urban...

conclusions the authors described their anesthetic experience of profound metabolic alkalosis with complex electrolyte abnormalities and provided a review of relevant literature. case presentation a 34-year-old female visited gachon university gil medical center, incheon, south korea during year 2015. she experienced aggravated renal function due to chronic hypokalemia and severe hypochloremic ...

BACKGROUND AND OBJECTIVES Occupational exposure to waste anesthetic gases in operating room (OR) without active scavenging system has been associated with adverse health effects. Thus, this study aimed to compare the trace concentrations of the inhaled anesthetics isoflurane and sevoflurane in OR with and without central scavenging system. METHOD Waste concentrations of isoflurane and sevoflu...

As an illustration, consider the following two-step adsorption cycle to purify helium diving gas. Helium diving gas is principally a mixture of oxygen and helium, when the diving chambers are depressurised, the contaminated gas will consist mainly of carbon dioxide, oxygen and helium. Traditionally this waste gas has been thrown away. The PSA cycle described below is a method of purifying this ...

In the past it was taught that local anesthetic should not be used with adrenaline for procedures in the extremities. This dogma is transmitted from generation to generation. Its truth has not been questioned, nor the source of the doubt. In many situations the benefit of use was not understood, because it was often thought that it was not necessary to prolong the anesthetic effect, since the p...

This report presents the results of a methane inventory in the solid waste sector of Ukraine. It considers the theoretical background of the methane generation process in solid waste, reviews methodologies used for methane generation assessment, and describes the methane inventory process in a transparent way. This study has been carried out with the purpose of Ukraine's compliance with the req...

At present, the main contributors to waste to energy are municipal solid waste, manufacturing waste and landfill gas. Probably we are all most familiar with the first (MSW), which involves the garbage that the garbage men pick up regularly at our homes and which goes to a landfill, a transfer station, or incinerator. Today we are going to introduce you to something relatively new on the alterna...

BACKGROUND Multiple anesthetic approaches exist for full-face laser resurfacing. The propofol-ketamine technique is reviewed as a reasonable alternative to providing adequate anesthesia for full-face laser resurfacing in the office environment. OBJECTIVE To report outcomes using propofol-ketamine opioid avoidance, room air, spontaneous ventilation monitored anesthesia care (MAC). METHOD A r...
