Agents that are capable of inducing a total or partial loss of sensation, especially tactile sensation and pain. They may act to induce general ANESTHESIA, in which an unconscious state is achieved, or may act locally to induce numbness or lack of sensation at a targeted site.
Drugs that block nerve conduction when applied locally to nerve tissue in appropriate concentrations. They act on any part of the nervous system and on every type of nerve fiber. In contact with a nerve trunk, these anesthetics can cause both sensory and motor paralysis in the innervated area. Their action is completely reversible. (From Gilman AG, et. al., Goodman and Gilman's The Pharmacological Basis of Therapeutics, 8th ed) Nearly all local anesthetics act by reducing the tendency of voltage-dependent sodium channels to activate.
Gases or volatile liquids that vary in the rate at which they induce anesthesia; potency; the degree of circulation, respiratory, or neuromuscular depression they produce; and analgesic effects. Inhalation anesthetics have advantages over intravenous agents in that the depth of anesthesia can be changed rapidly by altering the inhaled concentration. Because of their rapid elimination, any postoperative respiratory depression is of relatively short duration. (From AMA Drug Evaluations Annual, 1994, p173)
Agents that induce various degrees of analgesia; depression of consciousness, circulation, and respiration; relaxation of skeletal muscle; reduction of reflex activity; and amnesia. There are two types of general anesthetics, inhalation and intravenous. With either type, the arterial concentration of drug required to induce anesthesia varies with the condition of the patient, the desired depth of anesthesia, and the concomitant use of other drugs. (From AMA Drug Evaluations Annual, 1994, p.173)
Ultrashort-acting anesthetics that are used for induction. Loss of consciousness is rapid and induction is pleasant, but there is no muscle relaxation and reflexes frequently are not reduced adequately. Repeated administration results in accumulation and prolongs the recovery time. Since these agents have little if any analgesic activity, they are seldom used alone except in brief minor procedures. (From AMA Drug Evaluations Annual, 1994, p174)
A stable, non-explosive inhalation anesthetic, relatively free from significant side effects.
A nonflammable, halogenated, hydrocarbon anesthetic that provides relatively rapid induction with little or no excitement. Analgesia may not be adequate. NITROUS OXIDE is often given concomitantly.

Electrophysiological evidence for tetrodotoxin-resistant sodium channels in slowly conducting dural sensory fibers. (1/3062)

A tetrodotoxin (TTX)-resistant sodium channel was recently identified that is expressed only in small diameter neurons of peripheral sensory ganglia. The peripheral axons of sensory neurons appear to lack this channel, but its presence has not been investigated in peripheral nerve endings, the site of sensory transduction in vivo. We investigated the effect of TTX on mechanoresponsiveness in nerve endings of sensory neurons that innervate the intracranial dura. Because the degree of TTX resistance of axonal branches could potentially be affected by factors other than channel subtype, the neurons were also tested for sensitivity to lidocaine, which blocks both TTX-sensitive and TTX-resistant sodium channels. Single-unit activity was recorded from dural afferent neurons in the trigeminal ganglion of urethan-anesthetized rats. Response thresholds to mechanical stimulation of the dura were determined with von Frey monofilaments while exposing the dura to progressively increasing concentrations of TTX or lidocaine. Neurons with slowly conducting axons were relatively resistant to TTX. Application of 1 microM TTX produced complete suppression of mechanoresponsiveness in all (11/11) fast A-delta units [conduction velocity (c.v.) 5-18 m/s] but only 50% (5/10) of slow A-delta units (1.5 +info)

RINm5f cells express inactivating BK channels whereas HIT cells express noninactivating BK channels. (2/3062)

Large-conductance Ca2+- and voltage-activated BK-type K+ channels are expressed abundantly in normal rat pancreatic islet cells and in the clonal rat insulinoma tumor (RINm5f) and hamster insulinoma tumor (HIT) beta cell lines. Previous work has suggested that the Ca2+ sensitivity of BK channels in RIN cells is substantially less than that in HIT cells, perhaps contributing to differences between the cell lines in responsiveness to glucose in mediating insulin secretion. In both RIN cells and normal pancreatic beta cells, BK channels are thought to play a limited role in responses of beta cells to secretagogues and in the electrical activity of beta cells. Here we examine in detail the properties of BK channels in RIN and HIT cells using inside-out patches and whole cell recordings. BK channels in RIN cells exhibit rapid inactivation that results in an anomalous steady-state Ca2+ dependence of activation. In contrast, BK channels in HIT cells exhibit the more usual noninactivating behavior. When BK inactivation is taken into account, the Ca2+ and voltage dependence of activation of BK channels in RIN and HIT cells is essentially indistinguishable. The properties of BK channel inactivation in RIN cells are similar to those of inactivating BK channels (termed BKi channels) previously identified in rat chromaffin cells. Inactivation involves multiple, trypsin-sensitive cytosolic domains and exhibits a dependence on Ca2+ and voltage that appears to arise from coupling to channel activation. In addition, the rates of inactivation onset and recovery are similar to that of BKi channels in chromaffin cells. The charybdotoxin (CTX) sensitivity of BKi currents is somewhat less than that of the noninactivating BK variant. Action potential voltage-clamp waveforms indicate that BK current is activated only weakly by Ca2+ influx in RIN cells but more strongly activated in HIT cells even when Ca2+ current magnitude is comparable. Concentrations of CTX sufficient to block BKi current in RIN cells have no effect on action potential activity initiated by glucose or DC injection. Despite its abundant expression in RIN cells, BKi current appears to play little role in action potential activity initiated by glucose or DC injection in RIN cells, but BK current may play an important role in action potential repolarization in HIT cells.  (+info)

Comparison of local anesthetic activities between optical isomers of cis-1-benzoyloxy-2-dimethylamino-1,2,3,4-tetrahydronaphthalene. (3/3062)

The optical isomers of cis-1-benzoyloxy-2-dimethylamino-1,2,3,4-tetrahydronaphthalene (YAU-17) were compared for their local anesthetic activity, acute toxicity, spasmolytic activity, and partition coefficient between chloroform and phosphate buffer. 1-YAU-17 was more active than d-YAU-17 in blocking the conduction of action potentials in isolated frog sciatic nerves. The difference in local anesthetic activities between the optical isomers was further substantiated by in vivo tests for corneal anesthesia, intracutaneous anesthesia and sciatic nerve block in quinea-pigs. Similarly, the i.v. injection to mice revealed a higher toxicity for 1-YAU-17 as compared to its d-isomer. In these tests, the potency ratios of the enantiomers ranged from 2 to 4, and the racemate had an intermediate potency. On the contrary, no difference among the compounds was found in their liposolubility, partition coefficient, and spasmolytic activity examined with isolated guinea-pig ileum. These results indicate that the steric factors play an important role in the production of different local anesthetic activities between the optical isomers of YAU-17, and their local anesthetic potency tends to be correlated to their intravenous acute toxicity but not to their spasmolytic activity.  (+info)

Pharmacological studies on root bark of mulberry tree (Morus alba L.) (4/3062)

Pharmacological studies were done on the root bark of mulberry tree and pharmacological effects were compared with the clinical effects of "Sohakuhi" in Chinese medicine. n-Butanol- and water-soluble fractions of mulberry root had similar effects except for those on the cadiovascular system. Both fractions showed cathartic, analgesic, diuretic, antitussive, antiedema, sedative, anticonvulsant, and hypotensive actions in mice, rats, guinea pigs and dogs. There appears to be a correlation between the experimental pharmacological results and the clinical applications of mulberry root found in the literature on Chinese medicine.  (+info)

Evaluation of lidocaine as an analgesic when added to hypertonic saline for sclerotherapy. (5/3062)

PURPOSE: The efficacy of sclerosing agents for the treatment of telangiectasias and reticular veins is well established. The injection of these agents is often associated with pain, and it is not uncommon for sclerotherapists to include lidocaine with the sclerosants in an attempt to reduce the pain associated with treatment. However, there are concerns that this may reduce the overall efficacy of the treatment because of dilution of the sclerosant. Patient comfort and overall outcome associated with treatment using HS with lidocaine (LIDO) versus that using HS alone was compared. METHODS: Forty-two patients were prospectively entered into the study and randomized blindly to sclerotherapy with 23.4% HS or 19% LIDO. Study subjects and treating physicians were blinded to the injection solution used. Injection sites were chosen for veins ranging in size from 0.1 to 3 mm. Photographs of the area to be treated were taken, and the patients rated their pain. They were then observed at regular intervals for four months, and clinical data was collected. Thirty-five subjects completed the full follow-up period, and photographs of the injected area were taken again. Three investigators blinded to the treatment assignment then evaluated the photographs and scored the treatment efficacy according to a standardized system. RESULTS: In the HS group, 61.9% (13 of 21) patients rated their pain as none or mild, whereas 90.5% (19 of 21) of patients in the LIDO group had no or mild discomfort. This difference is significant, with a P value of.034. There was no difference in the overall efficacy of treatment between the two groups. The groups had similar rates of vein thrombosis and skin necrosis. CONCLUSION: Although lidocaine is often used with sclerosing agents, there are no previous reports in the literature to evaluate its effectiveness in reducing the pain experienced by the patient. In this study, patients receiving LIDO experienced significantly less discomfort at the time of injection than patients who received HS alone. There were no differences in the effectiveness of treatment or in the incidence of complications between the two groups.  (+info)

A study of local anaesthetics. Part 148. Influence of auxiliary substances on the surface tension, distribution coefficient and pharmaceutical availability from solutions of the potential drug VII. (6/3062)

The influence of auxiliary substances of the polyol group (glycerol, propylene glycol, sorbitol) and of their concentration (5, 10, 15 and 20% by weight) upon surface tension, distribution coefficient and pharmaceutical availability from solutions of the potential drug VII, viz., N-[2-(2-propoxyphenylcarbamoyloxy)-ethyl] piperidinium chloride was studied. The substances were applied as hydrogel humectants. It was found that their influence on the surface tension, distribution coefficient and pharmaceutical availability from solutions of the potential drug VII depended on the type as well as concentration of the auxiliary substance. From the viewpoints of use in formulations of the drug form, sorbitol used at 5 and 10% concentrations represented the optimum.  (+info)

Dose-response effects of spinal neostigmine added to bupivacaine spinal anesthesia in volunteers. (7/3062)

BACKGROUND: Intrathecal adjuncts often are used to enhance small-dose spinal bupivacaine for ambulatory anesthesia. Neostigmine is a novel spinal analgesic that could be a useful adjunct, but no data exist to assess the effects of neostigmine on small-dose bupivacaine spinal anesthesia. METHODS: Eighteen volunteers received two bupivacaine spinal anesthetics (7.5 mg) in a randomized, double-blinded, crossover design. Dextrose, 5% (1 ml), was added to one spinal infusion and 6.25, 12.5, or 50 microg neostigmine in dextrose, 5%, was added to the other spinal. Sensory block was assessed with pinprick; by the duration of tolerance to electric stimulation equivalent to surgical incision at the pubis, knee, and ankle; and by the duration of tolerance to thigh tourniquet. Motor block at the quadriceps was assessed with surface electromyography. Side effects (nausea, vomiting, pruritus, and sedation) were noted. Hemodynamic and respiratory parameters were recorded every 5 min. Dose-response relations were assessed with analysis of variance, paired t tests, or Spearman rank correlation. RESULTS: The addition of 50 microg neostigmine significantly increased the duration of sensory and motor block and the time until discharge criteria were achieved. The addition of neostigmine produced dose-dependent nausea (33-67%) and vomiting (17-50%). Neostigmine at these doses had no effect on hemodynamic or respiratory parameters. CONCLUSIONS: The addition of 50 microg neostigmine prolonged the duration of sensory and motor block. However, high incidences of side effects and delayed recovery from anesthesia with the addition of 6.25 to 50 microg neostigmine may limit the clinical use of these doses for outpatient spinal anesthesia.  (+info)

Comparison of three solutions of ropivacaine/fentanyl for postoperative patient-controlled epidural analgesia. (8/3062)

BACKGROUND: Ropivacaine, 0.2%, is a new local anesthetic approved for epidural analgesia. The addition of 4 microg/ml fentanyl improves analgesia from epidural ropivacaine. Use of a lower concentration of ropivacaine-fentanyl may further improve analgesia or decrease side effects. METHODS: Thirty patients undergoing lower abdominal surgery were randomized in a double-blinded manner to receive one of three solutions: 0.2% ropivacaine-4 microg fentanyl 0.1% ropivacaine-2 microg fentanyl, or 0.05% ropivacaine-1 microg fentanyl for patient-controlled epidural analgesia after standardized combined epidural and general anesthesia. Patient-controlled epidural analgesia settings and adjustments for the three solutions were standardized to deliver equivalent drug doses. Pain scores (rest, cough, and ambulation), side effects (nausea, pruritus, sedation, motor block, hypotension, and orthostasis), and patient-controlled epidural analgesia consumption were measured for 48 h. RESULTS: All three solutions produced equivalent analgesia. Motor block was significantly more common (30 vs. 0%) and more intense with the 0.2% ropivacaine-4 microg fentanyl solution. Other side effects were equivalent between solutions and mild in severity. A significantly smaller volume of 0.2% ropivacaine-4 microg fentanyl solution was used, whereas the 0.1% ropivacaine-2 microg fentanyl group used a significantly greater amount of ropivacaine and fentanyl. CONCLUSIONS: Lesser concentrations of ropivacaine and fentanyl provide comparable analgesia with less motor block despite the use of similar amounts of ropivacaine and fentanyl. This finding suggests that concentration of local anesthetic solution at low doses is a primary determinant of motor block with patient-controlled epidural analgesia after lower abdominal surgery.  (+info)

This randomized, double-blind study was designed to compare single injection pectoral nerve block (Pecs I and Pecs II) versus local anesthetic infiltration for ambulatory breast augmentation under monitored anesthesia care (MAC). In this randomized, double-blind, prospective study, 80 patients scheduled for breast augmentation under MAC using dexmedetomidine were divided into two groups. Pecs group: Ultrasound-guided pectoral nerve block was performed on both sides of the chest. Local anesthetic (LA) group: Local anesthetic infiltration was performed in the desired plane and skin incision site of each breast. The number of patients converted to general anesthesia was calculated. Postoperative pain intensity was measured using visual analog scale (VAS), and morphine consumption in the first 24 h and patient satisfaction were measured. The success rate of the ultrasound-guided block versus local infiltration to complete surgery without conversion to general anesthesia was statistically non-significant.

This problem has been dissolved according to the present invention thereby that one local anesthetic agent in the form of its base and as such having a melting point of 30 to 50 C., preferably prilocaine or tetracaine, is provided with one other local anesthetic agent in the form of its base and as such having a melting point of above 30 C., preferably above 40 C., preferably bensocaine, lidocaine, bupivacaine, mepivacaine, etidocaine or tetracaine which agents when brought and heated together form a homogenous oil having a melting of preferably below 40 C., more preferably below 25 C.
general anesthetic. Local anesthetics do not require the circulation as an intermediate carrier, and they usually are not transported to distant organs. Therefore, the actions of local anesthetics are largely confined to the structures with which they come into direct contact. Local anesthetics may provide analgesia in various parts of the body by topical application, injection in the vicinity of peripheral nerve endings and major nerve trunks, or via instillation within the epidural or subarachnoid spaces. The various local anesthetics differ with regard to their potency, duration of action, and degree of effects on sensory and motor fibers. Toxicity may be local or systemic. With systemic toxicity, the central nervous system (CNS) and cardiovascular systems typically are affected. ...
Note the lack of local anesthetics on that list. Lidocaine? No. Hyperbaric bupivacaine? No. Good ol tetracaine? Nope. All local anesthetics in the intrathecal space are off-label. Yet these are the very drugs that serve as the cornerstone for spinal anesthesia.. With a spinal needle and a few milliliters of local anesthetic like bupivacaine or lidocaine, we can achieve an anesthetic which enables surgeons to operate on the abdomen or lower extremities pain-free without any significant cardiopulmonary drawbacks. Sure, sympathectomies are a concern, but weve become extremely good at predicting and mitigating the effects of hypotension, tachy/bradycardias, etc ...

This paper shows experimental results obtained from a T100 microturbine connected with different volume sizes. The activity was carried out with the test rig developed at the University of Genoa for hybrid system emulation. However, these results apply to all the advanced cycles where a microturbine is connected with an additional external component responsible for volume size increase. Even if the tests were performed with a microturbine, similar analyses can be extended to large size turbines. A modular vessel was used to perform and to compare the tests with different volume sizes. To highlight the volume size effect, preliminary experimental results were carried out considering the transient response due to an on/off bleed valve operation. So, the main differences between system parameters obtained for a bleed line closing operation are compared considering three different volume sizes. The main results reported in this paper are related to surge operations. To produce surge conditions in ...
We reviewed the literature and found only one case series, published as a letter, that described complications associated with the use of pump systems for direct anesthetic infusion. This case series describes plastic surgery consultations for three patients referred by the same orthopedic surgeon after knee arthroplasties. 8 Two patients needed wound débridements and gastrocnemius flaps, and the third patient underwent repeated débridements and skin grafting. The likely cause of wound ischemia and necrosis was thought to be the infusion of bupivacaine with epinephrine. Reportedly, there was adequate drainage of the wound and no apparent compartment compression. The authors of the letter speculate that the adverse events were related to continuous infusion of epinephrine and subsequent vasoconstriction of the area. In adverse event reports to the FDA, some reports described similar adverse events with use of anesthetic infusion alone. These reports did not explicitly state that epinephrine was ...

The investigators propose a prospective blinded randomized control trial (RCT) to assess the efficacy and safety of a simple method of continuous infusion of a local anesthetic, ropivacaine, via a surgical wound to control pain after ureteropelvic junction (UPJ) stenosis correction in children during the first 48 hrs after surgery. The investigators hypothesize that this technique will provide greater pain relief post-operatively and reduce the need for systemic opioid use along with a reduction in associated side effects of such analgesics ...

The findings were extended to studies in an in vivo xenograft model. RESULTS:: Treatment of breast tumor cells with lidocaine and bupivacaine resulted in inhibition of cell ...
Adverse drug reactions (ADRs) are rare when it is administered correctly. Most ADRs relate to administration technique (resulting in systemic exposure) or pharmacological effects of anesthesia, however allergic reactions can rarely occur. Systemic exposure to excessive quantities of ropivacaine mainly result in central nervous system (CNS) and cardiovascular effects - CNS effects usually occur at lower blood plasma concentrations and additional cardiovascular effects present at higher concentrations, though cardiovascular collapse may also occur with low concentrations. CNS effects may include CNS excitation (nervousness, tingling around the mouth, tinnitus, tremor, dizziness, blurred vision, seizures followed by depression (drowsiness, loss of consciousness), respiratory depression and apnea). Cardiovascular effects include hypotension, bradycardia, arrhythmias, and/or cardiac arrest - some of which may be due to hypoxemia secondary to respiratory depression.[2] ...

Biodegradable controlled release microspheres for the prolonged administration of a local anesthetic agent, and a method for the manufacture thereof are disclosed. The microspheres are formed of a biodegradable polymer degrading significantly within a month, with at least 50% of the polymer degrading into non-toxic residues which are removed by the body within a two week period. Useful polymers include polyanhydrides, polylactic acid-glycolic acid copolymers and polyorthoesters containing a catalyst; polylactic acid-glycolic acid copolymers are preferred. Local anesthetics are incorporated into the polymer using a method that yields a uniform dispersion, preferably solvent casting. Prolonged release is obtained by incorporation of a glucocorticoid into the polymeric matrix or by co-administration of the glucocorticoid with the microspheres. The type of anesthetic and the quantity are selected based on the known pharmaceutical properties of these compounds.
Objectives: To investigate the quantitative impact of experience on competence in local anesthetic administration amongst final-year Bachelor of Dental Surgery (BDS) students.. Methods: A Longitudinal cohort study design was employed. Purposive sampling was used to enrol final year BDS students and assess their competence longitudinally over a full academic year. The assessment criteria and scoring structure were reviewed during inspection of the institution by the regulator and the external examiner.

In the following experiments, the use dependence of Na sup + current block by local anesthetics (i.e., phasic block) was studied. Na sup + currents were activated every second by voltage steps from -80 to -30 mV, first in control solution and then in the presence of local anesthetics. Control current and several consecutive currents recorded with 100-micro Meter bupivacaine are shown in Figure 4(A). The amplitudes of peak Na sup + currents as a function of pulse number for 0-(control solution), 3-, and 300-micro Meter bupivacaine (n = 8, 8, and 6, respectively) are given in Figure 4(B). Na sup + currents recorded in the presence of local anesthetic were normalized to first currents recorded in control solution. The strongest reduction in the amplitude was seen in the currents activated by the first two pulses (N1 and N2;Figure 4(B)). In the presence of 300-micro Meter bupivacaine, the Na sup + current activated by the second pulse was reduced by 40.0 +/- 4.9%(n = 6) compared with that activated ...

The major findings of this study are that infusion of clinically utilized local anesthetics after renal I/R injury significantly worsened renal function in rats. Exacerbation of renal function with local anesthetic treatment was associated with increased necrosis, apoptosis, and inflammation.. Our study is the first report to describe that local anesthetics worsen renal injury in rats after I/R in vivo. Renal I/R alone doubled Cr values 24 h after injury, with a complete return to baseline Cr values at 48 h after injury. However, chronic infusion with 5% lidocaine, 1% bupivacaine, or 2.5% tetracaine during the period of I/R caused a further doubling of Cr values at 24 h above those increases seen with I/R alone. Moreover, increases in Cr values persisted to 48 h. Thus chronic local anesthetic infusions not only augmented the initial rise in Cr values but added to the duration of renal insufficiency.. We next sought to illustrate the mechanism (necrosis, apoptosis, and/or inflammation) by which ...
ABSTRACT. Introduction: The peripheral nerve blockade produces high analgesic quality in knee surgery. Local anesthetics are used upon the base of its effectiveness and toxicity, so we decided to evaluate the postoperative analgesia through the comparison of ropivacaine (R) against bupivacaine (B) for femoral and sciatic blockade in the arthroscopic reconstruction of the anterior crossed ligament (ALC) repair. Methods: Study of cohort, randomized and comparative. There were studied patients submitted to ALC. Surgery being divided in two groups: R and B. Blockade was applied femoral and sciatic postoperative, the anesthetic place use in concentration of 0.25%, total volume of 40 mL for every nerve. VAS was evaluated at 6, 12, 18, 24 hours at rest and movement, analgesia time (ADT) and motor blockade time (MBT). Result: There were no differences in the demographic variables. The VAS, at rest and movement, was similar for both groups until 18 hours, when it significantly differed for the group R. ...
Nicolais answer is not entirely correct.. Background. The most common local anesthetics are all the -caine drugs - like novocaine, lidocaine, - and even cocaine has some of the same pharmacology, as well as other effects (in movies this is why cops might rub some white powder on their lips - if its cocaine, it will make their lips tingle; this is not standard training for non-movie police; also not advised for drug sellers or purchasers, because for exactly this reason cocaine is often cut with other -caines or other compounds that give a tingly feeling).. What all of these drugs do is to block voltage-gated sodium channels. These are the channels that propagate action potentials through axons and excitable dendrites. Other local anesthetics that arent used in the clinic, like tetrodotoxin from pufferfish, block the same types of channels. At sufficient concentrations, local anesthetics block all nervous activity: unlike @Nicolais answer, they do shut down nerves (as a brief note for ...

Anesthesia before wound repair can be accomplished with one of the two classes of local anesthetics: esters (e.g., procaine) and amides (e.g., lidocaine). Anesthesia is usually accomplished by local infiltration; pain on administration of the injection can be decreased by buffering the solution with sodium bicarbonate. Warming the anesthetic solution also decreases pain with infiltration. Prior administration of topical anesthetics such as tetracaine 1 percent can ameliorate injection pain. Alternative methods for local anesthesia include topical and regional applications. A topical combination of tetracaine, adrenaline and cocaine (TAC) has been shown to be an effective anesthetic in children and patients with face or scalp lacerations; however, serious adverse events have been reported. Eutectic mixture of local anesthetic (EMLA) cream has been useful, but the onset of anesthesia is delayed. Local anesthetics can be administered regionally by infiltrating around a regional sensory nerve. This ...

Whereas I support continued study of paravertebral catheter placement with continuous local anesthetic infusion, I caution against advocacy for a therapeutic intervention with associated risk and expense based on clinical experience in a series of patients without adequate study in a randomized, double-blind, placebo-controlled clinical trial. Before our trial, I was enthusiastic about the technique and was of the opinion that the results of the study would be unequivocally positive. I had observed that patients seemed to wake up with less pain and required less narcotic administration in the recovery area. Although these observations proved to be correct, patients were less comfortable after leaving the recovery room. From 6 to 12 h after nerve blockade, the treatment group used more patient-controlled morphine than the control group, making the cumulative morphine dose indistinguishable between groups by the 12th h. Although morphine usage may be an imperfect endpoint, we were unable to ...

PURPOSE: To assess aqueous humor lidocaine concentrations in 2 common regimens of topical anesthesia and after intracameral injection of the anesthetic agent. SETTING: University hospital eye clinic. METHODS: Twenty patients having routine cataract surgery were randomized into 3 groups: 1 given 3 drops of lidocaine 4% before surgery; 1 given 6 drops; 1 given 3 drops plus an intracameral injection of 0.1 mL lidocaine 1%. Lidocaine concentration was measured in aqueous humor samples taken before surgery. RESULTS: With 3 drops, aqueous lidocaine concentration was 1.4 micrograms/mL +/- 0.5 (SD) and with 6 drops, 4.3 +/- 1.5 micrograms/mL (P = .0015). With an intracameral injection, it was 341.8 +/- 152.6 micrograms/mL. CONCLUSION: Measurable amounts of lidocaine entered the anterior chamber in topical anesthesia, and more entered when more drops were given. It is likely that concentrations in this range could anesthetize the iris, but they are far lower than concentrations after an intracameral ...

Blockade of voltage-gated sodium (Na+) channels by local anesthetics represents the main mechanism for inhibition of impulse propagation. Local anesthetic-induced potassium (K+) channel inhibition is also known to influence transmission of sensory impulses and to potentiate inhibition. K+ channels involved in this mechanism may belong to the emerging family of background tandem pore domain K+ channels (2P K+ channels). To determine more precisely the effects of local anesthetics on members of this ion channel family, we heterologously expressed the 2P K+ channels TASK-2 (KCNK5), TASK-1 (KCNK3), and chimeric TASK-1/TASK-2 channels in oocytes of Xenopus laevis. TASK-2 cDNA-transfected HEK 293 cells were used for single-channel recordings. Local anesthetic inhibition of TASK-2 was dose-dependent, agent-specific, and stereoselective. The IC50 values for R-(+)-bupivacaine and S-(-)-bupivacaine were 17 and 43 μM and for R-(+)-ropivacaine and S-(-)-ropivacaine, 85 and 236 μM. Lidocaine (1 mM) inhibited TASK
INTRODUCTION. The narrow therapeutic index of 5% hyperbaric lidocaine on neuroaxis has been shown since the early 1990, when Cauda Equina syndrome was associated to its spinal administration via microcatheter in continuous infusion 1,2, after single pencil point needle injection 3,4 and repeated injections due to blockade failure 5.. Lidocaine concentration potentially able to determine nervous tissue injury is still not well established. Experimental studies in rats, in which the anesthetic was administered via spinal catheter, have shown neurotoxicity in concentrations varying from 2.5% 6 to 7.5% 7,8. The criticism to this model is that it does not reproduce the anesthetic technique used in the clinical practice 6.. This study aimed at investigating the effect on spinal cord and meninges of increasing spinal lidocaine concentrations in single injection through Quincke needle.. METHODS. After the Animal Experiment Ethical Committee approval, 40 adult mixed-breed dogs of both genders, weighing 7 ...
Intraneural introduction of local anesthetic belongs to the existing complications of peripheral nerves blockades. The damage of peripheral nerves is associated with the damaging effect of the injection needle and with the pressure caused by the introduction of local anesthetic. Purpose: Determine the pressure of the local anesthetic in fascial compartment of the sciatic nerve during his administration in the blockade of the sciatic nerve subgluteal access. Materials and Methods: Submitted blockade of the sciatic nerve subgluteal access in 22 patients with peripheral nerve electrostimulation under ultrasound guidance. To measure interstitial pressure system was used with the inclusion of a probe invasive blood pressure. Results: During the introduction of 1 ml in the fascial compartment of the sciatic nerve, the pressure of 0.77 psi (40 mmHg) was registered. In the course of the further introduction of local anesthetic up to 13 ml, the pressure did not alter validly (p > 0.05) and its average was 40 (35

Neurologic risks from needle placement, toxic anesthetic medications, and hematomas -- Houston, Texas Lawyer, Lawyer, Attorney at Law, Robert Painter, Taunya Painter
The patient is positioned as in a conventional axillary block. One 21 size hypodermic needle is inserted into the axillary sheath on each side of the axillary artery. Total 20ml (10ml through each needle) of local anaesthetic solution is injected and the needles are withdrawn. The ring is applied over the skin encircling the injection sites and pressure is applied on the ring by vertically pressing on the collars, which distributes the force on the ring. This pressure on the ring is transmitted to the axillary sheath sealing it on all sides which prevents escape of anaesthetic solution on all sides and confines it to the area inside the ring. The skin inside the ring is massaged to allow fast passage of anaesthetic solution around the nerves within the confines of the ring ...

The number of ambulatory surgical procedures is growing and local anesthesia represents the technique of choice for outpatients undergoing minor surgery. The aim of this study was to verify whether differences exist in postoperative pain relief using equipotent doses of two long-acting local anesthetics, ropivacaine and levobupivacaine, in patients who underwent minor breast surgery. A series of 86 consecutive women (median age=55, range=39-75 years) with small (,2 cm in size) breast masses requiring surgical excision were prospectively enrolled in the study. Patients were randomly selected to receive 75 mg/ml ropivacaine (group A, 42 patients) or 5 mg/ml levobupivacaine (group B, 44 patient). For post-surgical measurement of pain intensity a visual analog scale (VAS) was used. The age of the patients (56.4±9.6 vs. 56.7 ±9.5 years; p=0.88) and operative time (38.4 ± vs. 39.8 ±5.0 min; p=0.16), did not differ significantly between the groups (A vs. B).

AU - Ueda, Issaku. PY - 2004/10/10. Y1 - 2004/10/10. N2 - The surface tension and pH of aqueous solutions of three hydrochloric acid (HCl) - uncharged anesthetic (mepivacaine (MC), bupibacaine (BC) and dibucaine (DC)) mixtures were measured as a function of total molality and composition of local anesthetic in order to investigate the competitive surface-adsorption of uncharged and charged local anesthetics. The behavior of the surface tension versus total molality and pH versus total molality curves remarkably changed at the composition corresponding to an equimolar mixture. The pH measurements showed that uncharged and charged forms coexisted only at compositions more than the equimolar mixture. The partitioning quantities of respective uncharged and charged anesthetics into the surface-adsorbed film ...
1. This study was devised to test the hypothesis that dyspnoea could be mediated by unmyelinated vagal sensory nerve endings (type J receptors) situated at alveolar level in the lung.. 2. A modified jet nebulizer was used to generate an aerosol of local anaesthetic in particles small enough to allow alveolar deposition. Lignocaine (2% and 5%) produced aerosols with an arithmetic mean diameter (+sd) of 1.5+0.3 and 1.2+0.6 μm respectively, the mass median diameters being 1.7 (geometric standard deviation = 1.2) and 2.5 (geometric standard deviation = 1.7) μm respectively.. 3. In experimental animal models a vagally mediated tachypnoea may be induced acutely by pulmonary microembolism. This response is known to be mediated by unmyelinated pulmonary afferent nerves in the vagus. Local anaesthetic agents administered as small particles, but not as large particles, obtunded this response, which suggests that the aerosol was capable of penetration to alveolar level.. 4. Upon this background, a ...
Background Ropivacaine is a new amide local anesthetic, having therapeutic properties similar to those of bupivacaine but with a wider margin of safety. Bupivacaine is probably the most commonly used drug in obstetric epidural analgesia, even though laboratory studies have suggested that pregnancy increases the cardiotoxicity of bupivacaine but not of other local anesthetics. The current study was designed to reevaluate, in a random and blinded fashion, the systemic toxicity of bupivacaine and ropivacaine in nonpregnant and pregnant sheep. Methods Chronically prepared nonpregnant and pregnant ewes were randomized to receive an intravenous infusion of ropivacaine or bupivacaine at a constant rate of 0.5 mg.kg-1.min-1 until circulatory collapse. The investigators were blinded to the identity of local anesthetic. Heart rate, arterial blood pressure, and cardiac rhythm were monitored throughout the study. Arterial blood samples were obtained before infusion and at the onset of toxic manifestations, ...
This study reports an investigation of the pharmacological activity, cytotoxicity, and local effects of a liposomal formulation of the novel local anaesthetic ropivacaine (RVC) compared with its plain solution. RVC was encapsulated into large unilamellar vesicles (LUVs) composed of egg phosphatidylcholine, cholesterol and a-tocopherol (4:3:0.07, mole %). Particle size, partition coefficient determination and in-vitro release studies were used to characterize the encapsulation process. Cytotoxicity was evaluated by the tetrazolium reduction test using sciatic nerve Schwann cells in culture. Local anaesthetic activity was assessed by mouse sciatic and rat infraorbital nerve blockades. Histological analysis was performed to verify the myotoxic effects evoked by RVC formulations. Plain (RVCPLAIN) and liposomal RVC (RVCLUV) samples were tested at 0.125%, 0.25% and 0.5% concentrations. Vesicle size distribution showed liposomal populations of 370 and 130 nm (85 and 15%, respectively), without changes ...
Is regional anesthesia indicated?. 1. Should you avoid using local anesthetics?. No. His allergic reaction could have been an intravascular injection, a reaction to epinephrine added to the solution, or a reaction to a derivative of para-aminobenzoic acid, from Novacaines ester local anesthetic.. 2. What determines potency of local anesthetics?. Lipid solubility determines potency. The higher the solubility, the more potent the agent is.. 3. What determines duration of action of local anesthetics?. Protein binding determines duration of action. The more the protein binding, the longer the duration of action.. 4. What determines onset of action of local anesthetics?. pKa determines onset of action. The closer the pKa is to the tissue pH, the faster the onset. All local anesthetics are weak bases, so those with a pKa near 7.4 have more molecules that are lipid-soluble and unionized.. ...

Update on the clinical utility and practical use of ropivacaine in Chinese patients Man Li, Li Wan, Wei Mei, Yuke Tian Department of Anesthesiology, Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology, Wuhan, People's Republic of China Abstract: We reviewed the Chinese and English literature for efficacy and tolerability data as well as pharmacological properties of ropivacaine in Chinese patients. Ropivacaine is a long-acting amide local anesthetic agent that elicits nerve block via reversible inhibition of sodium ion influx in nerve fibers. The available evidence in the literature on anesthesia practice indicates that ropivacaine produces equally surgical sensory block and postoperative and obstetrics analgesia with good maternal and fetal outcome to those of bupivacaine or levobupivacaine. It appears to be associated with comparable onset, quality, and duration of sensory block, but with a lower incidence or grade of motor block, compared to bupivacaine. The
Local anaesthetics. Local anaesthetics are drugs which act on nerves to stop or block transmission of information. We often use local anaesthetics to block sensory nerves. This means that the painful stimulus cannot pass up to the brain and the animal does not feel the pain. Local anaesthetics will also affect motor nerves which cause the muscles to move. It can therefore cause temporary inhibition of muscle movement. Some drugs last a number of hours so also provide effective pain relief for the first evening after surgery.. Benefits of local anaesthetic use. Using local anaesthetics have been shown to have a number of benefits when used in people including:. ...
We assessed the effect of local anesthetics (LA) from different families such as esters (benzocaine), linear aminoamides (lidocaine) and cyclic aminoamides (bupivacaine) on the platelet aggregation induced by ADP. Liposomal formulations of the three LA, prepared with egg phosphatidylcholine: cholesterol a-tocopherol, were also tested. The three LA were able to inhibit platelet aggregation induced by ADP, in the following order: bupivacaine , lidocaine , benzocaine. After encapsulation into liposomes the inhibitory effect increased for all anesthetics studied, showing that aggregation tests could be used to assess the toxicity of new drug formulations ...
