Propofol Impairs Neurogenesis and Neurologic Recovery and Increases Mortality Rate in Adult Rats After Traumatic Brain Injury*

2013

Objective: Limited data are available on the influence of sedation for critical care therapy with the widely used anesthetic propofol on recovery from acute traumatic brain injury. To establish the influence of propofol on endogenous neurogenesis and functional recovery after traumatic brain injury, rats were sedated with propofol either during or 2 hours after experimental traumatic brain injury. Design: Randomized controlled animal study. Setting: University research laboratory. Subjects: One hundred sixteen male Sprague Dawley rats. Interventions: Mechanical brain lesion by controlled cortical impact. Measurements and Main Results: This study investigated the dose-dependent influence of …

Cerebral haemodynamic changes during propofol-remifentanil or sevoflurane anaesthesia: transcranial Doppler study under bispectral index monitoring

2006

Background. Sevoflurane or propofol–remifentanil-based anaesthetic regimens represent modern techniques for neurosurgical anaesthesia. Nevertheless, there are potential differences related to their activity on the cerebrovascular system. The magnitude of such difference is not completely known. Methods. In total 40 patients, treated for spinal or maxillo-facial disorders, were randomly allocated to either i.v. propofol–remifentanil or inhalational sevoflurane anaesthesia. Transcranial Doppler was used to assess changes in cerebral blood flow velocity, carbon dioxide reactivity, cerebral autoregulation and the bispectral index to assess the depth of anaesthesia. Results. Time-averaged mean f…

Sevoflurane Impairs Cerebral Blood Flow Autoregulation in Rats: Reversal by Nonselective Nitric Oxide Synthase Inhibition

2005

UNLABELLED In this study, we investigated the effects of 1.0 and 2.0 minimum alveolar anesthetic concentration (MAC) sevoflurane on cerebral blood flow (CBF) autoregulation before and after nonselective inhibition of nitric oxide (NO) synthase in rats. Rats were randomly assigned as follows: Group 1 (n = 8): 1.0 MAC sevoflurane; Groups 2 and 3 (n = 8 per group): 2.0 MAC sevoflurane. Assessment of autoregulation within a mean arterial blood pressure range of 140-60 mm Hg was performed by graded hemorrhage before and after administration of l-arginine methyl ester (l-NAME, 30 mg/kg IV, Groups 1 and 2) or during hypocapnia (Group 3). In 10 additional animals, brain tissue NO(2)(-) concentratio…

Inhalational or intravenous anesthetics for craniotomies? Pro inhalational.

2006

In neurosurgery, anesthesiologists and surgeons focus on the same target - the brain. The nature of anesthetics is to interact with brain physiology, leading to favorable and adverse effects. Research in neuroanesthesia over the last three decades has been dedicated to identifying the optimal anesthetic agent to maintain coupling between cerebral blood flow and metabolism, keep cerebrovascular autoregulation intact, and not increase cerebral blood volume and intracranial pressure.Sevoflurane is less vasoactive than halothane, enflurane, isoflurane, or desflurane. The context sensitive half-life is short and similar to that of desflurane, which translates into fast on and offset. Compared wi…

Isoflurane is associated with a similar incidence of emergence agitation/delirium as sevoflurane in young children ? a randomized controlled study

2006

Summary Background:  Children may be agitated or even delirious especially when recovering from general anesthesia using volatile anesthetics. Many trials have focused on the newer agents sevoflurane and desflurane but for the widely used isoflurane little is known about its potential to generate agitation. We investigated the emergence characteristics of small children after sevoflurane or isoflurane with caudal anesthesia for postoperative pain control. Methods:  After institutional approval and parental consent, anesthesia was randomly performed with sevoflurane (n = 30) or isoflurane (n = 29) in children at the age of 3.8 ± 1.8 years during surgical interventions on the lower part of th…

Economic Considerations of the Use of New Anesthetics

1998

UNLABELLED: Cost control in anesthesia is no longer an option; it is a necessity. New anesthetics have entered the market, but economic differences in comparison to standard anesthetic regimens are not exactly known. Eighty patients undergoing either subtotal thyroidectomy or laparoscopic cholecystectomy were randomly divided into four groups, with 20 patients in each group. Group 1 received propofol 1%/sufentanil, Group 2 received desflurane/sufentanil, Group 3 received sevoflurane/sufentanil, and Group 4 received isoflurane/sufentanil (standard anesthesia) for anesthesia. A fresh gas flow of 1.5-2 L/min and 60% N2O in oxygen was used for maintenance of anesthesia, and atracurium was given…

Aspetti etici e controllo di gestione dei farmaci antibiotici antibatterici

2010

Summary Introduction Antibacterial prescribing practices between 2004 and 2008 were investigated in the P. Giaccone University Hospital in Palermo, Italy to provide a foundation for critical analysis of the appropriateness of health-care resource usage. Materials and methods Antibiotic prescribing practices between 2004 and 2008 were analyzed in the hospital as a whole and in different specialty areas. Results were expressed as defined daily doses (DDD) as a function of bed-days, number of admissions, and Diagnosis Related Group (DRG) points. Results During the study period, increases were observed in the overall DDD per 100 bed-days (68.7 vs. 91.3) and the DDD per admission (4.53 vs. 5.54)…

Use of delamanid for M/XDR-TB treatment under programmatic conditions in Latvia

2016

Introduction. Since 2014 Delamanid (Dlm) was introduced in M/XDR-TB treatment under programmatic conditions. The aim of this study was to analyse experience of Dlm use. Methods. For all MDR-TB cases treatment regimens (Tx) are designed by MDR-TB expert committee. Dlm is prescribed for patients with risk of failure of Tx due to resistance or severe intolerance of key 2 nd line drugs. We analysed clinical and demographic data for all patients who received Dlm during the period of July 2014 to February 2016. Data were collected from patient9s medical records. Results. In total 20 MDR TB patients received Dlm: 3 female and 17 male with median age 46 years, including 2 children (11 and 13 years …
