introduction: although patients do not experience sever pain after laparoscopic surgery, most of them experience acute or chronic pain afterward. while conventional pain killers including nsaid and narcotics in laparoscopic surgery have specific side effects, their application is inevitable. this study compares the efficacy of local anesthetic drugs and conventional pain killers in post-operati...

intrathecal administration of midazolam has been reported to have antinociceptive action, and to be an effective analgesic agent. in this prospective double-blind study we aimed to evaluate the postoperative effects of intrathecal midazolam with lidocaine following perineal operation. forty patients were randomly allocated to two groups: 20 patients in the control group received 2 ml of 5% heav...

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...

BACKGROUND AND OBJECTIVES Leigh syndrome (LS) is a rare disease caused by abnormalities of mitochondrial energy generation. The central nervous system is most frequently affected, with psychomotor underdevelopment, seizures, nystagmus, ophthalmoparesis, optic atrophy, ataxia, dystonia, or respiratory failure. Surgical and anesthetic procedures stimulate the tracheal irritability, and could exac...

Diastolic Dysfunction (DD) is a well-described component of coronary artery disease (CAD), and is common among cardiac surgery patients.Managed care pressures have intensified recent trends of “fast-tracking” coronary artery bypass grafting (CABG) patients, leading to more reliance on volatile anesthetic gases such as isoflurane. However, volatile anesthetics are known to have the side-effect o...

BACKGROUND Previous cross-sectional studies have shown that job change due to breathing problems at the workplace (respiratory work disability) is common among adults of working age. That research indicated that occupational exposure to gases, dust and fumes was associated with job change due to breathing problems, although causal inferences have been tempered by the cross-sectional nature of p...

BACKGROUND Exposure of the OR staff to inhalational anesthetics has been proven by numerous investigators, but its potential adverse effect under the present technical circumstances is a debated issue. The aim of the present work was to test whether using a laminar flow air conditioning system exposure of the team to anesthetic gases is different if the anesthetist works in the sitting as compa...

Vasopressin increases the permeability of the total urinary bladder, an analogue of the mammalian renal collecting duct, to water and small solutes, especially the amide urea. We have observed that three general anesthetic agents of clinical importance, the gases methoxyflurane and halothane and the ultrashortacting barbiturate methohexital, reversibly inhibit vasopressin-stimulated water flow,...
