A simple, accurate and sensitive method for the microdetermination of benzocaine, lignocaine and procaine hydrochlorides in pure forms and in pharmaceutical formulations is described. The procedure is based on the reaction of those drugs in an aqueous acidic medium with p-benzoquinone to form charge-transfer complexes. The method has been used for the determination of 5.0-70, 5.0-60 and 5.0-90 ...

Introduction. Topical application of local anesthetics is currently considered to be the easiest, most effective, and convenient way for treatment of patients who may be undergoing superficial dermatosurgical procedures. Materials and Methods. This study compares the anesthetic potential of 2.5% lidocaine and 2.5% prilocaine topical cream with 7% lignocaine and 7% tetracaine combination cream f...

We have investigated if alfentanil acts via peripheral opioid receptors to relieve the pain which occurs on injection of propofol. Thirty seconds before induction of anaesthesia and immediately after a tourniquet at 50 mm Hg greater than systolic pressure was inflated on the upper arm, patients were given either placebo (n = 22), alfentanil 1 mg (n = 22) or lignocaine 40 mg (n = 22) via an i.v....

This study compared the anaesthetic effects of intramuscular injection of Ketamine (K) (15 mg/kg) with intramuscular injection of Ketamine (K) (15 mg/kg) and Lignocaine (L) (4 mg/kg) infiltration for laparocaecectomy in 12 layer chickens (1.1±0.06 Kg) randomized into two groups (K, 5 chickens and KL, 7 chickens). The duration of recumbency of the K-L group (100.3±16.4 min) was significantly lon...

Two groups of patients who requested extradural analgesia were studied in a within-patient controlled trial and received either 0.5% bupivacaine with adrenaline 5 mug/ml or 0.5% bupivacaine plain as the analgesic agent (first group) or 0.5% bupivacaine or 2% lignocaine both with adrenaline 5 mug/ml (second group). Arterial pressure, central venous pressure (CVP), maternal and foetal heart rate ...

A total of 124 subjects who were undergoing routine endoscopy were randomly assigned to one of three groups. All three groups received lignocaine throat spray. The first group additionally received midazolam, the second received hypnosis, whilst the third only received lignocaine throat spray. Although hypnotized patients were deemed by an independent observer to be less agitated than the other...

Three topical anesthetic agents namely Eutectic mixture of Local anesthetic 5% cream, Produit Dentaire ( 20% benzocaine) and Lignocaine 15% spray used in pediatric patients during various dental procedures requiring local anesthesia administration were evaluated in terms of onset of action and clinical efficacy for pain perception. In this study 210 patients aged between 6-14 years were randoml...
