BACKGROUND This report presents results from four preclinical studies evaluating safety and pharmacokinetics (PKs) of liposome bupivacaine following intravascular (intravenous [IV], intra-arterial [IA]), epidural, and intrathecal administration in dogs. METHODS Intravascular administration was initially tested in a pilot study to determine maximum tolerated doses, and then in an expanded stud...

objective: this study investigated the efficacy of bupivacaine wound infusion for pain control and opioid sparing effect after cesarean delivery. materials and methods: we conducted a randomized double blind, placebo controlled clinical trial on 60 parturients undergoing cesarean section at a university hospital in tehran. patients were randomized to receive a pump infusion system that was fill...

conclusions considering that tonsillectomy is one of the most common surgeries in children and produces a lot of pain, using a low risk medicine such as bupivacaine to recover child as soon as possible seems reasonable. results patients aged 4 to 13 years. the amount of postoperative pain was obviously less in the bupivacaine group than the other group. the mean time of postoperative fluid inta...

 Introduction: shorter hospital stay and less pain in comparison to open surgery considered to be major benefits for laparoscopic cholecystectomy. We compared the effect of intraperitoneal hydrocortisone plus bupivacaine with bupivacaine alone on pain relief following laparoscopic cholecystectomy.  Methods: Sixty two patients participated in this double-blind, randomized clinical trial. Pati...

Gaseous microemboli (GME) are an abnormal physiological occurrence during cardiopulmonary bypass and extracorporeal membrane oxygenation (ECMO). Several studies have correlated negative sequelae with exposure to increased amounts of GME. Hypobaric oxygenation is effective at eliminating GME in hollow-fiber microporous membrane oxygenators. However, hollow-fiber diffusion membrane oxygenators, w...

This work attempts to evaluate the cognitive aspects of the acclimatization ability of mice submitted to simulated altitude. Critical altitudes were detected by evaluating open field activity, combined or not with object recognition tasks, at different acute simulated altitudes. Results showed impaired cognitive abilities at approximately 3,733 m and above. To evaluate acclimatization capabilit...

BACKGROUND The Chinese bayberry (Myrica rubra Sieb. and Zucc.) is a subtropical fruit native to China, with unique flavor, sweet and sour taste, and high nutrition and health values. The fruit is highly perishable and susceptible to mechanical injury, physiological deterioration and fungal decay once harvested. This study was to investigate the effect of hypobaric storage on the quality of Chin...

Aeromedical evacuation, an important component in the care of many patients with traumatic brain injury (TBI), particularly in war zones, exposes them to prolonged periods of hypobaria. The effects of such exposure on pathophysiological changes and outcome after TBI are largely unexplored. The objective of this study was to investigate whether prolonged hypobaria in rats subjected to TBI alters...

BACKGROUND The inadvertent systemic administration of bupivacaine has been associated with fatal cardiovascular collapse. Systemic bupivacaine may affect neural control of the cardiovascular system in addition to having toxic actions on the heart. The study tested the hypothesis that systemic bupivacaine has toxic effects on brainstem cardiorespiratory control. METHODS The working heart-brain...

INTRODUCTION DepoFoam bupivacaine is a novel liposomal formulation of bupivacaine designed to provide prolonged postsurgical analgesia. This dose-ranging study evaluated extent and duration of analgesia following administration of DepoFoam bupivacaine in patients undergoing total knee arthroplasty (TKA). METHODS Efficacy, safety, and pharmacokinetics of DepoFoam bupivacaine doses of 133, 266,...
