BACKGROUND Reperfusion ventricular fibrillation after aortic cross clamp is one of the important complications of open cardiac surgery and its prevention could reduce myocardial injuries. This study aimed to evaluate the efficacy of single dose of amiodarone or lidocaine by the way of pump circuit three minutes before aortic cross clamp release and compare the results with normal saline as plac...

BACKGROUND Many infectious diseases that cause significant morbidity and mortality, especially in the developing world, could be preventable through vaccination. The effort to produce safe, thermally stable, and needle-free mucosal vaccines has become increasingly important for global health considerations. We have previously demonstrated that a thermally stable nanoemulsion, a mucosal adjuvant...

The serum and urine levels of lidocaine and two active dealkylated metabolites, monoethylglycinexylidide (MEGX) and glycinexylidide (GX), were determined by HPLC in 33 cardiac patients receiving lidocaine for more than 1 day. Clinical assessment of nervous system toxicity was carried out at the time of blood drawing. The ratios in serum of MEGX to lidocaine and of GX to lidocaine were 0.36 +/- ...

Off-pump coronary artery bypass grafting (OPCABG) has recently gained popularity. During OPCABG, patients remain vulnerable to ischemic-reperfusion injury due to a temporary coronary occlusion without any active cardioprotection. Some strategies such as ischemic preconditioning (IP) and an intracoronary shunt have been applied with a view to minimizing the effects of ischemia, but the effects o...

In vitro and in vivo testing was performed to establish the feasibility of a totally implantable pump system to deliver antiarrhythmic agents. In vitro flow characteristics suggested predictable day to day delivery with acceptably small variations in flow with changes in reservoir volume or temperature. During 3 months of in vitro testing, procainamide and bretylium were found suitable for long...

Topical anesthesia of the airway is a necessary for awake intubation and is usually achieved using lidocaine delivered by various means. Although some experts favor the use of airway blocks, a more common approach is to use pure topical methods in combination with "spray as you go" techniques. Once the topicalization is complete, the patient should be able to easily tolerate the use of an oral ...

In a double-blind group sequential trial the efficiency of an oxytocin nasal spray in enhancing lactation was studied during the first five days after delivery in women who had given birth prematurely. The cumulative volume of breast milk obtained between the second and fifth days after delivery was 3.5 times greater in primiparas given oxytocin than in primiparas given placebo. There was no si...
