Abstract Background Knowledge of risk factors for postoperative urinary retention may guide appropriate and timely catheterization. We aimed to determine independent catheterization in general surgical patients. In addition, we calculated bladder filling rate assessed the time spontaneous voiding or used patients previously determined individual maximum capacity as threshold Methods Risk were p...

BACKGROUND Local anaesthetics are known to induce apoptosis in clinically relevant concentrations. Hitherto, it is unknown what determines the apoptotic potency of local anaesthetics. Therefore, we compared apoptosis induction by local anaesthetics related to their physicochemical properties in human neuronal cells. METHODS Neuroblastoma cells (SHEP) were incubated with eight local anaestheti...

BACKGROUND Several studies have suggested that the likelihood of paresthesia may depend on the local anesthetic used. The purpose of this study was to determine if the type of local anesthetic administered had any effect on reports of paresthesia in dentistry in the United States. METHODS The authors obtained reports of paresthesia involving dental local anesthetics during the period from Nov...

OBJECTIVE Paresthesia is an adverse event that may be associated with the administration of local anesthetics in dentistry. The purpose of this retrospective study was to analyze cases of paresthesia associated with local anesthetic injection that were voluntarily reported to Ontario"s Professional Liability Program (PLP) from 1999 to 2008 inclusive, to see if the findings were consistent with ...

INTRODUCTION True allergy to local anesthetics, especially lidocaine, is uncommon. Most adverse reactions to this group of medications are classified as psychomotor, autonomic or toxic. In the case of suspected hypersensitivity to local anesthetics, skin testing is considered to be a useful tool - patch tests and intradermal tests for delayed hypersensitivity and skin prick tests and intraderma...

INTRODUCTION Previous studies have reported high levels of success with intraseptal injection for various dental procedures but provide limited information on the use of the injection during endodontic treatment. Therefore, the purpose of this prospective study was to determine the anesthetic efficacy of the supplemental intraseptal technique in mandibular posterior teeth diagnosed with symptom...

AIMS This pilot prospective, randomised, crossover study of positive aspiration frequency in intra-ligamental anaesthesia (ILA) was conducted with the following aims: (1) to determine the frequency of positive aspiration of blood after the administration of ILA at lower first molars, and (2) to evaluate the depth of the pulpal anaesthesia of lower first molars after positive or negative aspirat...
