Manuela Herrera reports from the 10th Emergency and Critical Care UK annual congress, hosted by Vets Now, which was held in Harrogate last November. More than 500 small animal veterinary surgeons, veterinary nurses, practice managers and receptionists attended the meeting to learn more about all aspects of emergency care.

Randomized Controlled TrialDifferent volumes of injectate using electrostimulator and blinded techniques for brachial plexus block in dogs.
To compare different volumes of injectate using electrostimulator (ES)-guided and blind brachial plexus blockade (BPB) techniques in dogs. Prospective, randomised, blinded study. Fifty-eight healthy adult purpose-bred beagle dogs. ⋯ When an ES is not available, the blind technique with 1 ml/kg is also acceptable. However, when performing an ES-guided BPB, volumes as low as 0.2 ml/kg can be used. As volume is increased, the musculocutaneous nerve becomes more likely to be targeted.

Randomized Controlled TrialThe effects of subarachnoid administration of hyperbaric solutions of bupivacaine or ropivacaine in xylazine-sedated calves undergoing surgery.
The aim of this study was to compare the effects of subarachnoid administration of hyperbaric solutions of bupivacaine or ropivacaine in xylazine-sedated calves undergoing surgery. Subarachnoid anaesthesia was performed with either 20 mg of hyperbaric bupivacaine (bupivacaine group (BG), n=10) or 30 mg of hyperbaric ropivacaine (ropivacaine group (RG), n=10) into the lumbar dural space of 20 calves in a randomised, prospective clinical trial. Systolic (SBP), diastolic (DBP) and mean (MBP) blood pressure, heart rate (HR), respiratory rate, rectal temperature were recorded after sedation (time 0), and up to 120 minutes after injection. ⋯ Onset of anaesthesia (mean±sd; BG, 5±1 minutes; RG, 7±1 minutes) and duration of anaesthesia (mean±sd; BG, 153±32 minutes; RG, 86±12 minutes) were significantly different between groups. Analgesic scores were significantly higher than baseline from 5 to 120 min, and from 7 to 85 min in BG and RG, respectively. Subarachnoid administration of hyperbaric solutions of bupivacaine produced faster onset and longer duration of anaesthesia than ropivacaine.
