brachial plexus block using lidocaine/ epinephrine or lidocaine/ xylazine in fat-tailed sheep

چکیده
this blinded, randomized experimental study was designed to evaluate the analgesic effects of adding epinephrine or xylazine to lidocaine solution for brachial plexus block (bpb) in sheep. nine healthy, fat-tailed female lambs (26.6 ± 1.5 kg) were randomly allocated into three groups: lidocaine 2%, 5 mg kg-1 (lid, n = 6), lidocaine (5 mg kg-1) with epinephrine 5 µg ml-1 (lidep, n = 6) or lidocaine (5 mg kg-1) with xylazine 0.05 mg kg-1 (lidxy, n = 6). each animal was tested twice. the sheep received a total volume of 0.25 ml kg-1 for bpb. a nerve stimulator was used to locate the nerves of the brachial plexus. onset and duration of analgesia of the forelimb were evaluated using superficial and deep pin prick and pinching of skin with a hemostat clamp. heart and respiratory rates, and rectal temperature were recorded before and at predetermined intervals following the completion of the block. brachial administration of lid, lidep or lidxy produced forelimb analgesia within 11.3, 11.0 and 7.0 minutes, respectively. the mean duration of analgesia was 100.0 min in lid and 133.2 min in lidep group. the mean duration of analgesia in lidxy group (186.8 min) was significantly longer compared with lid group. in lidep group a significant increase in heart rate occurred 5 min after drug administration. heart rate decreased from 35 to 80 minin sheep received lidxy. in conclusion, the addition of xylazine to lidocaine solution for bbp provided a prolonged duration of action without any adverse effects in fat-tailed sheep.

This blinded, randomised experimental study was designed to compare the analgesic effects of lumbosacral epidural administration of lidocaine-epinephrine or lidocaine-xylazine combinations in fat-tailed sheep. Nine healthy fat-tailed male lambs (mean ± s.d. age, 4.6 ± 0.4 months; weight, 24.6 kg ± 2.5 kg) were randomly allocated into four groups of six sheep: lidocaine 2% (LID), lidocaine-e...
متن کاملDexamethasone added to lidocaine prolongs axillary brachial plexus blockade.
Different additives have been used to prolong regional blockade. We designed a prospective, randomized, double-blind study to evaluate the effect of dexamethasone added to lidocaine on the onset and duration of axillary brachial plexus block. Sixty patients scheduled for elective hand and forearm surgery under axillary brachial plexus block were randomly allocated to receive either 34 mL lidoca...
متن کاملEvaluation of lidocaine and tetracaine mixture in axillary brachial plexus block.
The mixture of 1% lidocaine and 0.2% tetracaine with 1:200,000 epinephrine, so-called "supercaine," has been used extensively for axillary brachial plexus blockade for several decades. Since the advent of bupivacaine, the supercaine mixture has fallen into relative disuse despite its record of effectiveness and safety. No studies have been done recently to evaluate quality of anesthesia, durati...
متن کاملPharmacokinetics of Lidocaine Hydrochloride Administered with or without Adrenaline for the Paravertebral Brachial Plexus Block in Dogs
Adrenaline is known to prolong the duration of local anesthesia but its effects on the pharmacokinetic processes of local anesthetic drugs are not fully understood. Our objective was to develop a compartmental model for quantification of adrenaline's impact on the pharmacokinetics of perineurally-injected lidocaine in the dog. Dogs were subjected to paravertebral brachial plexus block using lid...
