The effect of local anaesthesia on anaesthetic requirements for feline ovariectomy     

Zilberstein LF  Moens YP  Leterrier E 《Veterinary journal (London, England : 1997)》2008,178(2):214-218

A dose of supplementary ketamine was used to evaluate the anaesthetic sparing effect of adding local anaesthesia to general anaesthesia in cats undergoing ovariectomy. Fifty-six healthy cats were randomly assigned to receive lidocaine 2% (group L) as skin infiltration (1 mg kg(-1)), topical application (splash block) on both the ovaries (2 mg kg(-1), each) and on abdominal muscular layers (1 mg kg(-1)), or an equal volume of NaCl 0.9% at the same sites (group S). Anaesthesia was induced with a mixture of 20 microg kg(-1) medetomidine and 5 mg kg(-1) ketamine administered intramuscularly. Rectal temperature, ECG, heart rate and respiratory rate were measured continuously. Ketamine supplemental boli (1 mg kg(-1), intravenously) were administered in response to movements during surgery. Local lidocaine significantly reduced the need for supplementary ketamine. All animals were returned to their owners without complications. With this protocol, local anaesthetics reduced the need for injectable anaesthetic during feline ovariectomy.  相似文献   

Anaesthetic sparing effect of local anaesthesia of the ovarian pedicle during ovariohysterectomy in dogs

ObjectiveTo evaluate the effect of local anaesthesia of the mesovarium on end-tidal isoflurane (Fe′_iso) concentration and vital parameters during canine ovariohysterectomy.Study designProspective, randomized, blinded study.AnimalsTwenty client-owned dogs undergoing elective ovariohysterectomy. Mean age 1.7 (±0.53, SD) years and mean body weight 21 kg (±5.9, SD).MethodsPre-medication was with intravenous acepromazine (0.02 mg kg⁻¹) and methadone (0.1 mg kg⁻¹). Anaesthesia was induced with propofol and maintained with isoflurane in oxygen. One group (n = 10) received local infiltration of the mesovarium with 0.5 mL lidocaine 2% and one group (n = 10) with 0.5 mL NaCl 0.9%. Heart (HR) and respiratory rates (fr), invasive mean arterial blood pressure (MAP) and Fe′_isowere recorded. The Fe′_iso was adjusted according to changes in HR, RR and MAP. Time points used for comparison were T1 (after induction of anaesthesia before surgery), T2 (after lidocaine infiltration of the mesovarium) and T3 (surgical manipulation of the ovaries). Data were analysed using a mixed model for repeated measurement anova and the Tukey adjustment. Results are presented as mean ± SD; p < 0.05 was considered significant.ResultsIn both groups, HR and fr remained stable at the three time points. Mean values ranged from 84 to 94 beats minute⁻¹ and from 10 to 14 breaths minute⁻¹. The Fe′_iso was significantly lower at T3 compared to T1 and mean values ranged from 0.95% to 1.24%. The mean arterial blood pressure was significantly higher at T3 compared to T1 and mean values ranged from 58 to 96 mm Hg. At none of the time points were there significant differences between the two groups for HR, fr, MAP or Fe′_iso.ConclusionNeither an isoflurane sparing effect nor a difference in autonomic response to surgery was demonstrated following local anaesthesia of the mesovarium.Clinical relevanceThere appeared to be minimal benefit from local anaesthesia of the mesovarium during this study.  相似文献

Chemical Characteristics of Precipitation at an Atlantic Station     

Cabon  Jean Yves 《Water, air, and soil pollution》1999,111(1-4):399-416

Weekly or half-monthly bulk rainwater samples were collected over 3 yr (1993–1995) at Porspoder, an Atlantic station near Brest, France. They were analyzed for 0.08 M HNO3-leachable trace metals Cd, Cu, Fe, Mn, Ni, Pb and Zn by direct electrothermal atomic absorption spectrometry. Major ions and nitrogen species (NO3- and NH4+) in precipitation were determined by ion chromatography. In coastal precitation, a high correlation was observed for major ions having a seawater origin (Na+, CL- and Mg2+. Zn, Cd, Cu, Ni and Pb were well correlated indicating their anthropogenic origin. In the case of nitrogen species and nssSO42- a high correlation with Zn was observed, taken as an anthropogenic pollution tracer. Major ions and nitrogen species were determined according to wind sector direction showing clearly the impact of the pollution at this station attributed to continental air masses. A relative constancy of pH values in all wind directions was observed. Due to an important oceanic influence, trace metal concentrations and annual deposition densities were significantly lower at Porspoder than at North Sea coastal stations. In the case of nitrogen species, the relatively higher concentration levels probably indicated a significant local agricultural contribution.  相似文献   

Geosmin causes off‐flavour in arctic charr in recirculating aquaculture systems     

Stéphanie Houle  Kevin K Schrader  Nathalie R Le François  Yves Comeau  Mourad Kharoune  Steven T Summerfelt  Arianne Savoie  Grant W Vandenberg 《Aquaculture Research》2011,42(3):360-365

The ‘earthy’ and ‘muddy’ off‐flavours in pond‐reared fish are due to the presence of geosmin or 2‐methylisoborneol in the flesh of the fish. Similar off‐flavours have been reported in fish raised in recirculating aquaculture systems (RAS); however, little information is available regarding the cause of these off‐flavours. Our hypothesis was that earthy and muddy off‐flavour compounds, found previously in pond‐raised fish, are also responsible for off‐flavours in fish raised in RAS. In this preliminary study, we examined water, biofilms in RAS and fillets from cultured arctic charr known to have off‐flavours and requiring depuration using instrumental [solid‐phase microextraction procedure and gas chromatograph‐mass spectrometry (GC‐MS)] and human sensory analyses. Geosmin was present in the samples taken from the biofilter and on the side walls of the tanks. Two‐methylisoborneol was only found in low levels in the samples. The GC‐MS results indicated the presence of geosmin in the fillets (705 ng kg^?1), but lower levels were found in the water (30.5 ng L^?1). Sensory analyses also detected an earthy flavour (i.e., geosmin presence) in the fillets, and, therefore, it appears that geosmin is the main compound responsible for the off‐flavour in RAS. Further studies are being performed to identify the microorganisms responsible for geosmin production in RAS.  相似文献   

Effects of blue shrimp Litopenaeus stylirostris and goldlined rabbitfish Siganus lineatus in mono‐ and polyculture on production and environmental conditions          下载免费PDF全文

Trung Cong Luong  Hugues Lemonnier  Sebastien Hochard  Florence Royer  Yves Letourneur 《Aquaculture Research》2017,48(4):1368-1379

This study was conducted to compare the effects of shrimp and rabbitfish in mono‐ and polyculture stocked at high biomass on production and environmental conditions in a mesocosm system. Shrimp (14 g) and/or rabbitfish (19 g) were stocked in four treatments with different density but with the same total biomass (236 g m^?2), including shrimp monoculture (SM) (17 shrimp m^?2), shrimp–fish polyculture (SF) (11 shrimp and 4 rabbitfish m^?2), fish–shrimp polyculture (FS) (6 shrimp and 8 rabbitfish m^?2) and fish monoculture (FM) (12 rabbitfish m^?2). After 10 weeks of experiment, shrimp survival and biomass were low in the treatments where shrimp were dominant (SM, SF), while rabbitfish survival and biomass were high in all the treatments. Shrimp mortality was assumed to be related to an excess of the system carrying capacity (CC). Results suggested that CC is linked to shrimp biomass/density rather than the system eutrophication level. The ecosystem became heterotrophic as daily feed supply was beyond 7 g m^?2 per day. This threshold corresponded to the environmental CC of the semi‐intensive shrimp culture system. Under these conditions, the combination of high fish biomass and low shrimp biomass appeared as the most valuable in terms of system performances.  相似文献   

Ecoviability for ecosystem‐based fisheries management          下载免费PDF全文

Reconciling food security, economic development and biodiversity conservation is a key challenge, especially in the face of the demographic transition characterizing many countries in the world. Fisheries and marine ecosystems constitute a difficult application of this bio‐economic challenge. Many experts and scientists advocate an ecosystem approach to manage marine socio‐ecosystems for their sustainability and resilience. However, the ways by which to operationalize ecosystem‐based fisheries management (EBFM) remain poorly specified. We propose a specific methodological framework—viability modelling—to do so. We show how viability modelling can be applied using four contrasted case‐studies: two small‐scale fisheries in South America and Pacific and two larger‐scale fisheries in Europe and Australia. The four fisheries are analysed using the same modelling framework, structured around a set of common methods, indicators and scenarios. The calibrated models are dynamic, multispecies and multifleet and account for various sources of uncertainty. A multicriteria evaluation is used to assess the scenarios’ outcomes over a long time horizon with different constraints based on ecological, social and economic reference points. Results show to what extent the bio‐economic and ecosystem risks associated with the adoption of status quo strategies are relatively high and challenge the implementation of EBFM. In contrast, strategies called ecoviability or co‐viability strategies, that aim at satisfying the viability constraints, reduce significantly these ecological and economic risks and promote EBFM. The gains associated with those ecoviability strategies, however, decrease with the intensity of regulations imposed on these fisheries.  相似文献   

Shoot‐produced,light‐dependent factors are partially involved in the expression of the arbuscular mycorrhizal (AM) status of AM host and non‐host plants     

Horst Vierheilig  Berta Bago  Sylvain Lerat  Yves Pich 《植物养料与土壤学杂志》2002,165(1):21-25

Arbuscular mycorrhizal (AM) colonization and hyphal attachment to the roots of a host plant, bean, and a non‐host plant, lupin, were compared when grown either with light or in the dark with the AM fungus Glomus mosseae. When grown with light, bean roots were heavily colonized whereas lupin roots showed no signs of colonization, no formation of appressoria and only scarce hyphal attachment to the roots. In contrast to roots of plants grown with light, to living roots of beans and lupins grown in the dark many hyphae were attached and appressoria were formed. The role of shoot produced, light‐dependent factors in the expression of the AM mycotrophic status of AM host and non‐host plants is discussed.<?show $6#>  相似文献
