BACKGROUND Spinal anesthesia is the most common regional anesthesia conducted for many surgical procedures. Multiple factors can affect the success, the side effects, and patient satisfaction with the procedure. This study was undertaken prospectively to discover factors affecting dissatisfaction and refusal of spinal anesthesia. METHODS Starting in December 2007, patients who underwent spina...

Introduction: there is no consensus on the ideal anesthesia for hemorrhoidectomy in ambulatory facilities. spinal anesthesia and venous propofol associated with local perianal block (combined anesthesia) are frequently used, and their direct costs may be crucial for the anesthesia type selection. the objective of this study was to compare the direct costs of anesthesia-related materials in hemo...

BACKGROUND AND OBJECTIVE To determine whether patients prefer topical anesthesia or subconjunctival anesthesia for intravitreal injection. PATIENTS AND METHODS Consecutive patients receiving bilateral simultaneous injections of anti-vascular endothelial growth factor agents were asked to participate in this within-patient, prospective, single-blinded, randomized, factorial study. Fifty-seven ...

Anesthesia is frequently used to facilitate physiological monitoring during interventional animal studies. However, its use may induce cardiovascular (central and peripheral), respiratory, thermoregulatory depression, confounding results in anesthetized animals. Despite the wide utility of guinea pigs as a translational platform, anesthetic protocols remain unstandardized for extended studies t...
