BACKGROUND The increase in remifentanil concentration during haemorrhagic shock and the difference between this effect and that for propofol are not fully understood. We investigated the influence of haemorrhage on the pseudo-steady-state remifentanil concentration in a porcine model and compared the changes with those for propofol. METHODS After infusion of remifentanil (0.5 µg kg⁻¹ min⁻¹) a...

remifentanil is an ultra short acting opioid that is suitable for many operations and is wildly used for induction and maintenance of anesthesia. in this article we have reported the incidence of abdominal pain after cataract surgery in patients with remifentanil based anesthesia. this study is a randomized single blind clinical trial on 300 patients who were candidates for elective cataract su...

We measured the blood concentration of propofol in a patient with delayed emergence from propofol-nitrous oxide anesthesia. A 78-year-old man underwent subtotal gastrectomy under both epidural and propofol-nitrous oxide anesthesia and did not regain consciousness soon after termination of propofol infusion. Preoperative laboratory examination revealed anemia and a low blood total protein concen...

We describe a system for monitoring and controlling i.v. anaesthesia in rats using burst suppression ratio (BSR) detection in the extradural EEG. After bolus injection, peak BSR values of 95% were achieved with propofol 8 mg kg-1, etomidate 3.5 mg kg-1 and alphaxalone 4.5 mg kg-1. Thiopental 32 mg kg-1 produced a peak BSR of 70% (larger doses were not tolerated). Recovery was fastest with propo...

----------------------------------------------------------------------------------------------------- Abstract: Paediatric bronchoscopy requires a deep level of anaesthesia of relatively short duration. This prospective randomized study compared the effectiveness of a low-dose infusion of propofol in combination with either dexmedetomidine, or midazolam for intravenous anaesthesia in paediatric...

Urolithiasis is a common clinical condition of almost all domestic animals but higher incidence has been recorded in bovine and caprine [1]. Several anaesthetic techniques with different drugs have been used for the management of urolithiasis. Total intravenous anaesthesia (TIVA) for short procedures seems to carry a lower risk of intraanaesthetic death than volatile agents [2]. In veterinary p...
