Caudal analgesia is a very popular route to provide intraoperative and postoperative analgesia in children because of its simple technique, predictable level of blockade, high success rate and smooth recovery. It can be used mainly for perineal and sub umbilical procedures. Ropivacaine, the S-enantiomer of the amide local anesthetic, produces differential neural blockade, with lesser motor bloc...

Abstract Objective: To evaluate and compare the analgesic effects of caudal epidural administration of lidocaine (LIDO), caudal laser radiation and epidural lidocaine plus laser radiation in horses. Study design: A blinded, randomized, prospective, experimental cross-over study. Animals: Five healthy horses, 15.7 +/- 4.9 years of age, weighing 240 +/- 37 kg. Methods: The...

Acetylcholine (ACh) plays important roles in the modulation of activity and plasticity of primary sensory cortices, thus influencing sensory detection and integration. We examined this in urethane-anesthetized rats, comparing cholinergic modulation of short latency, large amplitude field postsynaptic potentials (fPSPs) in the visual cortex (V1) evoked by stimulation of the ipsilateral lateral g...

Background TRPV1 (transient receptor potential vanilloid subfamily member 1) is a pain signaling channel highly expressed in primary sensory neurons. Attempts for analgesia by systemic TRPV1 blockade produce undesirable side effects, such as hyperthermia and impaired heat pain sensation. One approach for TRPV1 analgesia is to target TRPV1 along the peripheral sensory pathway. Results For func...

INTRODUCTION Brachial plexus blockade is a time-tested technique for upper limb surgeries. The classical approach using paresthesia technique is a blind technique and may be associated with a higher failure rate and injury to the nerves and surrounding structures. To avoid some of these problems, use of peripheral nerve stimulator and ultrasound techniques were started which allowed better loca...

Previous studies have demonstrated that volatile anesthetics could produce local anesthesia. Emulsified isoflurane at 8% has been reported to produce epidural anesthetic effect in rabbits. This study was designed to investigate the long-term epidural anesthetic effect of emulsified halothane in rabbits. In this study, 40 healthy adult rabbits (weighting 2.0-2.5 kg) with an epidural catheter wer...

Epidural blockade is becoming one of the most useful and versatile procedures in modern anesthesiology. Bupivacaine is a long acting amide local anaesthetic which is widely used since many years. However, it is associated with a number of side effects like Central Nervous System (CNS) toxicity and cardiotoxicity. Ropivacaine is a newly introduced long acting amide local anaesthetic drug in Indi...

To evaluate the hypothesis that adding dexmedetomidine to ropivacaine prolongs axillary brachial plexus block. Forty-five patients of ASA I~II and aged 25-60 yr who were scheduled for elective forearm and hand surgery were randomly divided into 3 equal groups and received 40 ml of 0.33% ropivacaine + 1 ml dexmedetomidine (50 μg) (Group DR1), 40 ml of 0.33% ropivacaine + 1 ml dexmedetomidine (10...

INTRODUCTION The present study compared the effect of bupivacaine and bupivacaine + sufentanil on hemodynamic parameters and characteristics of spinal anesthesia in elderly patients undergoing transurethral resection of the prostate (TURP) under spinal anesthesia. TECHNICAL CONSIDERATIONS The study included 40 American Society of Anesthesiologists (ASA) I-III patients scheduled to undergo TUR...

BACKGROUND Long-lasting forms of synaptic plasticity have been shown to depend on changes in gene expression. Although many studies have focused on the regulation of transcription and translation during learning-related synaptic plasticity, regulated protein degradation provides another common means of altering the macromolecular composition of cells. RESULTS We have investigated the role of ...
