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.

Transcranial magnetic stimulation (TCMS) causes leg muscle contractions, but the neural structures in the brain that are activated by TCMS and their relationship to these leg muscle responses are not clearly understood. To elucidate this, we concomitantly recorded leg muscle responses and thoracic spinal cord-evoked potentials (SCEPs) after TCMS for the first time in 10 awake, neurologically intact human subjects. In this report we provide evidence of direct and indirect activation of corticospinal neurons after TCMS. In three subjects, SCEP threshold (T) stimulus intensities recruited both the D wave (direct activation of corticospinal neurons) and the first I wave (I1, indirect activation of corticospinal neurons). In one subject, the D, I1, and I2 waves were recruited simultaneously, and in another subject, the I1 and I2 waves were recruited simultaneously. In the remaining five subjects, only the I1 wave was recruited first. More waves were recruited as the stimulus intensity increased. The presence of D and I waves in all subjects at low stimulus intensities verified that TCMS directly and indirectly activated corticospinal neurons supplying the lower extremities. Leg muscle responses were usually contingent on the SCEP containing at least four waves (D, I1, I2, and I3).  (+info)

Increased reading speed for stories presented during general anesthesia. (2/1145)

BACKGROUND: In the absence of explicit memories such as the recall and recognition of intraoperative events, memory of auditory information played during general anesthesia has been demonstrated with several tests of implicit memory. In contrast to explicit memory, which requires conscious recollection, implicit memory does not require recollection of previous experiences and is evidenced by a priming effect on task performance. The authors evaluated the effect of a standardized anesthetic technique on implicit memory, first using a word stem completion task, and then a reading speed task in a subsequent study. METHODS: While undergoing lumbar disc surgery, 60 patients were exposed to auditory materials via headphones in two successive experiments. A balanced intravenous technique with propofol and alfentanil infusions and a nitrous oxide-oxygen mixture was used to maintain adequate anesthesia. In the first experiment, 30 patients were exposed randomly to one of the two lists of 34 repeated German nouns; in the second experiment, 30 patients were exposed to one of two tapes containing two short stories. Thirty control patients for each experiment heard the tapes without receiving anesthesia. All patients were tested for implicit memory 6-8 h later: A word stem completion task for the words and a reading speed task for the stories were used as measures of implicit memory. RESULTS: The control group completed the word stems significantly more often with the words that they had heard previously, but no such effect was found in the anesthetized group. However, both the control and patient groups showed a decreased reading time of about 40 ms per word for the previously presented stories compared with the new stories. The patients had no explicit memory of intraoperative events. CONCLUSIONS: Implicit memory was demonstrated after anesthesia by the reading speed task but not by the word stem completion task. Some methodologic aspects, such as using low frequency words or varying study and test modalities, may account for the negative results of the word stem completion task. Another explanation is that anesthesia with propofol, alfentanil, and nitrous oxide suppressed the word priming but not the reading speed measure of implicit memory. The reading speed paradigm seems to provide a stable and reliable measurement of implicit memory.  (+info)

Description of local adaptation of national guidelines and of active feedback for rationalising preoperative screening in patients at low risk from anaesthetics in a French university hospital. (3/1145)

OBJECTIVE: To describe the effect of local adaptation of national guidelines combined with active feedback and organisational analysis on the ordering of preoperative investigations for patients at low risk from anaesthetics. DESIGN: Assessment of preoperative tests ordered over one month, before and after local adaptation of guidelines and feedback of results, combined with an organisational analysis. SETTING: Motivated anaesthetists in 15 surgical wards of Bordeaux University Hospital, Region Aquitain, France. SUBJECTS: 42 anaesthetists, 60 surgeons, and their teams. MAIN OUTCOME MEASURES: Number and type of preoperative tests ordered in June 1993 and 1994, and the estimated savings. RESULTS: Of 536 patients at low risk from anaesthetics studied in 1993 before the intervention 80% had at least one preoperative test. Most (70%) tests were ordered by anaesthetists. Twice the number of preoperative tests were ordered than recommended by national guidelines. Organisational analysis indicated lack of organised consultations and communication within teams. Changes implemented included scheduling of anaesthetic consultations; regular formal multidisciplinary meetings for all staff; preoperative ordering decision charts. Of 516 low risk patients studied in 1994 after the intervention only 48% had one or more preoperative tests ordered (p < 0.05). Estimated mean (SD) saving for one year if changes were applied to all patients at low risk from anaesthesia in the hospital 3.04 (1.23) mFF. CONCLUSIONS: A sharp decrease in tests ordered in low risk patients was found. The likely cause was the package of changes that included local adaptation of national guidelines, feedback, and organisational change.  (+info)

Drug-induced heart failure. (4/1145)

Heart failure is a clinical syndrome that is predominantly caused by cardiovascular disorders such as coronary heart disease and hypertension. However, several classes of drugs may induce heart failure in patients without concurrent cardiovascular disease or may precipitate the occurrence of heart failure in patients with preexisting left ventricular impairment. We reviewed the literature on drug-induced heart failure, using the MEDLINE database and lateral references. Successively, we discuss the potential role in the occurrence of heart failure of cytostatics, immunomodulating drugs, antidepressants, calcium channel blocking agents, nonsteroidal anti-inflammatory drugs, antiarrhythmics, beta-adrenoceptor blocking agents, anesthetics and some miscellaneous agents. Drug-induced heart failure may play a role in only a minority of the patients presenting with heart failure. Nevertheless, drug-induced heart failure should be regarded as a potentially preventable cause of heart failure, although sometimes other priorities do not offer therapeutic alternatives (e.g., anthracycline-induced cardiomyopathy). The awareness of clinicians of potential adverse effects on cardiac performance by several classes of drugs, particularly in patients with preexisting ventricular dysfunction, may contribute to timely diagnosis and prevention of drug-induced heart failure.  (+info)

Characterization of the electrophysiological and pharmacological effects of 4-iodo-2,6-diisopropylphenol, a propofol analogue devoid of sedative-anaesthetic properties. (5/1145)

1. Several derivatives and analogues of the general anaesthetic 2,6-diisopropylphenol (propofol) have been recently synthesised with the aim of exploring the structure-activity relationships. 2. In the present study, the effects of one such compound, 4-iodo-2,6-diisopropylphenol (4-I-Pro), on gamma-aminobutyric acid type A (GABA(A)) receptors in vitro were compared with its in vivo effects in rodents. Human GABA(A) receptors were expressed in Xenopus oocytes, and the actions of 4-I-Pro on receptor function were compared with those of propofol by two-electrode voltage-clamp recording. 3. Similar to propofol, 4-I-Pro directly activated Cl- currents in the absence of GABA at all combinations of receptor subunits tested. However, the efficacy of 4-I-Pro in inducing direct activation of alpha1beta2gamma2S receptors was markedly less than that of propofol. 4. Similarly to propofol, 4-I-Pro potentiated in a concentration-dependent manner GABA-evoked Cl- currents measured at different GABA(A) receptor constructs. 5. As expected, intraperitoneal injection of propofol induced sedation, ataxia, and loss of the righting reflex in rats. In contrast, administration of 4-I-Pro failed to produce any of these behavioural effects. 6. Administration of 4-I-Pro to rats reduced in a dose-dependent manner the incidence of tonic-clonic seizures induced by pentylenetetrazol and induced an anticonflict effect as measured in the Vogel test. 7. Microdialysis revealed that, like propofol, administration of 4-I-Pro reduced acetylcholine release in the hippocampus of freely moving rats. 8. These results demonstrate that para-substitution of the phenol ring of propofol with iodine yields a compound that exhibits anticonvulsant and anticonflict effects, but is devoid of sedative-hypnotic and anaesthetic properties. Thus, 4-I-Pro possesses pharmacological characteristics more similar to anxiolytic and anticonvulsant drugs than to general anaesthetics.  (+info)

Women emerge from general anesthesia with propofol/alfentanil/nitrous oxide faster than men. (6/1145)

BACKGROUND: Recovery from general anesthesia is governed by pharmacodynamic and pharmacokinetic factors. Gender has not previously been recognized as a factor influencing the time to emergence from general anesthesia. METHODS: This multicenter study was originally designed to measure the effects of the bispectral index on intraoperative anesthetic management and patient recovery. We compared the wake-up and recovery times of 274 adults after propofol/alfentanil/nitrous oxide anesthesia. Patients were randomly assigned to have the titration of propofol performed with or without the use of bispectral index monitoring. Specific guidelines were given for the titration of drugs. The aim in all cases was to provide a safe anesthetic with the fastest possible recovery. RESULTS: There was a significant reduction in propofol dose, time to eye opening, and response to verbal command when the anesthetic was titrated using the bispectral index. Unexpectedly, gender proved to be a highly significant independent predictor for recovery time. Women woke significantly faster than men: the time from end of anesthesia to eye opening was 7.05 versus 11.22 min, P < 0.05, and response to verbal command was 8.12 versus 11.67 min, P < 0.05. These differences were significant at all four study sites and in each treatment group. Men consistently had prolonged recovery times compared to women, P < 0.001. There was no difference in the dose of anesthetic used between gender. CONCLUSIONS: Gender appears to be an important variable in recovery from general anesthesia. These findings may explain the increased reported incidence of awareness in women (three times more frequent) and support the need to include gender as a variable in pharmacokinetic and pharmacodynamic studies of anesthetic drugs.  (+info)

Ethanol directly depresses AMPA and NMDA glutamate currents in spinal cord motor neurons independent of actions on GABAA or glycine receptors. (7/1145)

Ethanol is a general anesthetic agent as defined by abolition of movement in response to noxious stimulation. This anesthetic endpoint is due to spinal anesthetic actions. This study was designed to test the hypothesis that ethanol acts directly on motor neurons to inhibit excitatory synaptic transmission at glutamate receptors. Whole cell recordings were made in visually identified motor neurons in spinal cord slices from 14- to 23-day-old rats. Currents were evoked by stimulating a dorsal root fragment or by brief pulses of glutamate. Ethanol at general anesthetic concentrations (50-200 mM) depressed both responses. Ethanol also depressed glutamate-evoked responses in the presence of tetrodotoxin (300 nM), showing that its actions are postsynaptic. Block of inhibitory gamma-aminobutyric acidA and glycine receptors by bicuculline (50 microM) and strychnine (5 microM), respectively, did not significantly reduce the effects of ethanol on glutamate currents. Ethanol also depressed glutamate-evoked currents when the inhibitory receptors were blocked and either D, L-2-amino-5-phosphonopentanoic acid (40 microM) or 6-cyano-7-nitroquinoxaline-2,3-dione disodium (10 microM) were applied to block N-methyl-D-aspartate or alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid/kainate receptors, respectively. The results show that ethanol exerts direct depressant effects on both alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid and N-methyl-D-aspartate glutamate currents in motor neurons. Enhancement of gamma-aminobutyric acidA and glycine inhibition is not required for this effect. Direct depression of glutamatergic excitatory transmission by a postsynaptic action on motor neurons thus may contribute to general anesthesia as defined by immobility in response to a noxious stimulus.  (+info)

Alphaxalone activates a Cl- conductance independent of GABAA receptors in cultured embryonic human dorsal root ganglion neurons. (8/1145)

Whole cell and cell-attached patch-clamp techniques characterized the neurosteroid anesthetic alphaxalone's (5alpha-pregnane-3alpha-ol-11,20-dione) effects on GABAA receptors and on Cl- currents in cultured embryonic (5- to 8-wk old) human dorsal root ganglion neurons. Alphaxalone applied by pressure pulses from closely positioned micropipettes failed to potentiate the inward Cl- currents produced by application of GABA. In the absence of GABA, alphaxalone (0.1-5.0 microM) directly evoked inward currents in all dorsal root ganglion neurons voltage-clamped at negative membrane potentials. The amplitude of the current was directly proportional to the concentration of alphaxalone (Hill coefficient 1.3 +/- 0.15). The alphaxalone-induced whole cell current was carried largely by Cl- ions. Its reversal potential was close to the theoretical Cl- equilibrium potential, changing with a shift in the external Cl- concentration as predicted by the Nernst equation for Cl- ions. And because the alphaxalone-current was not suppressed by the competitive GABAA receptor antagonist bicuculline or by the channel blockers picrotoxin and t-butylbicyclophosphorothionate (TBPS; all at 100 microM), it did not appear to result from activation of GABAA receptors. In contrast to GABA-currents in the same neurons, the whole cell current-voltage curves produced in the presence of alphaxalone demonstrated strong inward rectification with nearly symmetrical bath and pipette Cl- concentrations. Fluctuation analysis of the membrane current variance produced by 1.0 microM alphaxalone showed that the power density spectra were best fitted to double Lorentzian functions. The elementary conductance for alphaxalone-activated Cl- channels determined by the relationship between mean amplitude of whole cell current and variance was 30 pS. Single-channel currents in cell-attached patches when the pipette solution contained 10 microM alphaxalone revealed a single conductance state with a chord conductance of approximately 29 pS. No subconductance states were seen. The current-voltage determinations for the single-channels activated by alphaxalone demonstrated a linear relationship. Mean open and shut times of single alphaxalone-activated channels were described by two exponential decay functions. Taken together, the results indicate that in embryonic human DRG neurons, micromolar concentrations of alphaxalone directly activate Cl- channels whose electrophysiological and pharmacological properties are distinct from those of Cl- channels associated with GABAA receptors.  (+info)

Voltage-gated Na(+) channels (Na(+) channels) mediate the rising phase of action potentials in neurons and excitable cells. Nine subtypes of the alpha subunit (Na(v)1.1-Na(v)1.9) have been shown to form functional Na(+) channels to date. Recently, anesthetic concentrations of volatile anesthetics and ethanol were reported to inhibit Na(+) channel functions, but it is not known whether all subtypes are inhibited by anesthetics. To investigate possible subtype-specific effects of anesthetics on Na(+) channels, mRNA of Na(v)1.2, Na(v)1.4, Na(v)1.6, and Na(v)1.8 alpha subunit-encoded genes were injected individually or together with a beta subunit mRNA into Xenopus oocytes. Na(+) currents were recorded using the two-electrode voltage-clamp technique. Isoflurane, at clinically relevant concentrations, inhibited the currents produced by Na(v)1.2, Na(v)1.4, and Na(v)1.6 by approximately 10% at the holding potential of -90 mV and by approximately 30% at -60 mV, but it did not affect the Na(v)1.8-mediated

Thirty-three patients with unrelenting CRPS were treated using this novel approach developed by Dr. Graeme E. Correll, BE, MBBS, in Mackay, Queensland, Australia. Pain relief and the duration of this relief appeared impressive. After only one treatment, there was complete relief in 76% (25) of the group. 54% of the patients remained free of pain for more than three months, 31% for more than six months. Although the relief of pain did not last indefinitely, it was noted that following a second treatment given to 12 of the patients, the outcome was improved. In this retreated group 58% remained pain free for more than a year and almost 33% experienced relief for over three years. The most frequent side effect was a feeling of inebriation with less frequent effects including hallucinations, dizziness, light-headedness and nausea ...
There is great concern about the possible harmful effects of exposure to volatile anesthetics. The current study aimed at evaluating, for the first time, the effects of occupational exposure to anesthetic gases on physicians who work in operating rooms, by determining several inflammatory cytokines. Plasma inflammatory cytokines (IL-1β, -6, -8, -10, -12, TNF-α) were investigated in 30 individuals who were allocated into two groups of 15: the exposed group, consisting of operating room medical personnel exposed to a mixture of anesthetic gases for 3 years, and a control group composed of medical personnel not exposed to anesthetic gases. The concentrations of volatile anesthetics were measured in the operating room by means of an infrared portable analyzer Our findings suggest an increase of the pro-inflammatory IL-8 (p , 0.05) in medical personnel exposed to high concentrations of anesthetic gases, even for a relatively short period.. ...

Anesthetics are a group of drugs used for both induction and maintenance of anesthesia as well as for pre-operative sedation. These drugs possess a high potential for addiction and physical dependence and abuse of anesthetics such as propofol and lidocaine is a major issue also among health professionals. Recreational abuse of anesthetic drugs and related designer analogs including ketamine, ?-hydroxybutyrate (GHB) and lidocaine have steadily increased around the world. The rise is attributed to their wide availability through online clandestine drug markets and their popularity as
There is no published experience with desflurane during breastfeeding. Because the serum half-life of desflurane in the mother is short and the drug is not expected to be absorbed by the infant, no waiting period or discarding of milk is required. Breastfeeding can be resumed as soon as the mother has recovered sufficiently from general anesthesia to nurse.[1] When a combination of anesthetic agents is used for a procedure, follow the recommendations for the most problematic medication used during the procedure. In one study, breastfeeding before general anesthesia induction reduced requirements of sevoflurane and propofol compared to those of nursing mothers whose breastfeeding was withheld or nonnursing women.[2] It is possible that requirements for other anesthetic agents would be affected similarly.

Wilhelmina Childrens Hospital, UMC Utrecht, Utrecht, Netherlands. Background:. An increasing number of animal- and human studies indicate a potential harmful effects of general anesthesia during critical stage of neurodevelopment. Experimental and clinical studies emphasize that younger age (, 3 yr), higher dose (,1 MAC) and longer duration (,1 hr) of anesthesia are potential risk factors for anesthetic neurotoxicity. However, the translation of these risk factor to procedures potentially at risk has not been performed yet. Therefore, we tried to identify number and type of procedures potentially at risk for the anesthetic neurotoxicity.. Objective:. To quantify and to identify the type of procedures potentially at risk for the anesthetic neurotoxicity. From experimental studies we defined that the children younger than 3 years receiving 300%min sevoflurane are at risk.. Design:. We analyzed a retrospective cohort study of all patients between 0 and 18 years of age anesthetized between January ...

The possibility of anesthetic neurotoxicity was first suggested more than 15 years ago with findings of apoptosis in the brains of rodents after ethanol exposure during critical periods of neurodevelopment. A similar neuroapoptotic effect was soon identified in anesthetic agents and linked to long-term functional consequences. Since then, nearly all commonly used N-methyl-D-aspartate (NMDA) antagonists and γ-amino butyric acid (GABA) agonists have been evaluated and were found to result in neurotoxic effects in a variety of animal species, including non-human primates.1 Hundreds of preclinical studies have now been published demonstrating effects with anesthetic doses relevant to humans and using monitoring standards similar to those used for clinical care in children. Despite the presence of this robust body of preclinical data, however, the clinical evidence is much sparser ...

BACKGROUND: Improving operating room safety and efficiency has received much attention over the past decade. This however has been relatively minimally translated into labor and delivery operating suites. In our academic practice, we have noted that prolonged delays in surgical start times may significantly contribute to sooner anesthetic ware and subsequent maternal exposure to supplemental anesthetics/analgesics. Within the context of improving both safety and efficiency, we sought to evaluate the average time interval between intrathecal anesthetic placement and surgical start. OBJECTIVE: Evaluate the average time between placement of intrathecal anesthetic to surgical incision during routine cesarean section. Secondary objectives included: (1) the frequency of supplemental anesthetic adjuncts utilized, in reference to both anesthetic technique as well as intra-operative times, and (2) the evaluation of neonatal outcomes based upon Apgar scoring at 1 and 5 minutes.

The phrase anesthesia identifies any temporary, medically-induced condition which brings about any combination of amnesia, incapacity to experience pain, lack of muscle reactions, lack of responsiveness, and decreased stress response. Anesthetics may include more than one forms of medication, based on the wanted effect.. Anesthesia is frequently employed prior to medical procedures, like surgery. Therefore, patients dont feel the suffering or stress which they might well feel as if they were conscious or able to feel.

LASERSOHN, L.. Anaesthetic considerations for paediatric laparoscopy. S. Afr. j. surg. [online]. 2011, vol.49, n.1, pp.22-26. ISSN 2078-5151.. Children, infants and neonates represent an anaesthetic challenge because of age-specific anatomical and physiological issues.

There are a number of factors related to the animal that impact on the quality of anesthesia. These factors should be considered when the type of anesthetic agent is being chosen.. Species: Different species require different doses of anesthetic agents. This applies particularly to the injectable anesthetics. In general, the smaller animals require a higher dose in mg/kg of a given anesthetic than larger animals. Familiarity with the effects of an anesthetic agent in one species should not be assumed in another species. The volatile anesthetics are more consistent in their application between species. The mean alveolar concentration of the anesthetic agent required for anesthesia is similar among species and this is controlled by the concentration of the agent in the inspired gases. Differences in the respiratory tract in birds (fixed lungs, air sacs) and other non-mammalian species must be considered when administering inhalation anesthetics.. Strain: Strain differences have been noted even ...
My project investigates the mechanism of action of the anesthetic, dexmedetomidine. One model proposes that the drug binds exclusively to receptors in the locus coeruleus, preventing norepinephrine release. Previous studies showed that absence of norepinephrine alone was sufficient for increased sensitivity to volatile anesthetics. We test the hypothesis that dexmedetomidine does not act solely at this nucleus, using transgenic mice lacking norephinephrine. With EEG recordings as a measure of anesthetic sensitivity, we compare the signals during wakefulness with those following intravenous anesthetic injection. We expect dexmedetomidine to produce no effect in the genetically-modified mice given the absence of norepinephrine.. ...
A novel catheter apparatus for use in delivering an anesthetic agent or other fluid medicament to the portion of subcutaneous tissue through which a catheter device has been inserted into a patient, thereby allowing the catheter device to be retracted without causing pain or discomfort to the patient. The catheter device has an indwelling cannula adapted for insertion through subcutaneous tissue into a patients body. A sheath is selectively disposed about the cannula so as to be positioned within the subcutaneous tissue once the cannula has been inserted into the body. The sheath may include a plurality of longitudinal bores which act as a lumen to provide fluid medicament to delivery holes on the outside of the sheath. The delivery holes permit the anesthetic agent or fluid medicament to be delivered to the subcutaneous tissue. A light permeable hub means may be used to maintain a fluid tight connection between the sheath means and a storage container for anesthetic agent or fluid medicament.
For most of the 1900s, it was widely believed that ethanol and the volatile anesthetics exerted their effects in vivo in a nonspecific manner, through the disordering of cell membrane lipids. The Meyer-Overton correlation of anesthetic potency with lipophilicity and the observation that agents with markedly dissimilar structures could all produce the same behavioral end point made it appear unlikely that volatile anesthetic agents had discrete protein binding sites. By analogy, inhaled drugs of abuse, which also vary greatly in their chemical structures, were also thought to nonspecifically influence neuronal function (Balster, 1998). The demonstration that pharmacologically relevant concentrations of volatile anesthetic agents and alcohols affect the functioning of lipid-free proteins such as firefly luciferase (Franks and Lieb, 1984) promoted a shift in research focus toward protein sites of anesthetic action. Among these protein sites, the ligand-gated ion channels, particularly the GABAA, ...

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. ...

Whats the difference between local and general anaesthetic, If you are having an operation then you will most probably be having either a local anaesthetic or a general anaesthetic before having the operation.
Induction of anesthesia is facilitated by diffusion of an inhaled anesthetic drug into the brain and spinal cord. Diffusion throughout the body proceeds until the drugs partial pressure within the various tissues is equivalent to the partial pressure of the drug within the lungs.[3] Healthcare providers can control the rate of anesthesia induction and final tissue concentrations of the anesthetic by varying the partial pressure of the inspired anesthetic. A higher drug partial pressure in the lungs will drive diffusion more rapidly throughout the body and yield a higher maximum tissue concentration. Respiratory rate and inspiratory volume will also effect the promptness of anesthesia onset, as will the extent of pulmonary blood flow.[4] The partition coefficient of a gaseous drug is indicative of its relative solubility in various tissues. This metric is the relative drug concentration between two tissues, when their partial pressures are equal (gas:blood, fat:blood, etc.). Inhalational ...
The role of extra-synaptic receptors in the regulation of excitation and inhibition in the brainhas attracted increasing attention. Because activity in the extra-synaptic receptors plays a role inregulating the level of excitation and inhibition in the brain, they may be important in determiningthe level of consciousness. This paper reviews briefly the literature on extra-synaptic GABAand NMDA receptors and their affinity to anesthetic drugs. We propose a neural populationmodel that illustrates how the effect of the anesthetic drug propofol on GABAergic extra-synapticreceptors results in changes in neural population activity and the electroencephalogram (EEG). Our results show that increased tonic inhibition in inhibitory cortical neurons cause a dramaticincrease in the power of both delta and alpha bands. Conversely, the effects of increased tonicinhibition in cortical excitatory neurons and thalamic relay neurons have the opposite effect anddecrease the power in these bands. The increased delta
The morphology of the electroencephalogram (EEG), has long been known to change in response to anaesthetic agents. Recently, Fourier analysis has allowed these changes to be quantified in terms of the frequency composition of the EEG. This has allowed sophisticated pharmacokinetic/pharmacodynamic investigation of centrally acting agents as well as comparison of the effects of different classes of drugs on central nervous system function. Despite this, the application of the EEG as an aid to the monitoring of adequacy of anaesthesia has been disappointing. This may be due to the pharmacological complexity of modern clinical anaesthetic practice as well as to the many other variables which can affect the EEG in the clinical environment. The horse is unusual because of the high mortality rate associated with anaesthesia as well as the relative pharmacological simplicity of the anaesthetic techniques used in this species. There are few published reports of the effects of anaesthetic agents on the ...
Alfred Einhorn (27 February 1856 - 21 March 1917) was a Jewish German chemist most notable for first synthesizing procaine in 1905 which he patented under the name Novocain .[citation needed] Until that time the primary anesthetic in use was cocaine, however its undesirable side effects (including toxicity and addiction) led scientists to seek out newer anesthetic drugs. Novocain was found to be comparatively safe and effective, although its anesthetic effects were weaker than cocaine and some patients proved highly allergic. However, none of the other anesthetics developed during this period proved more effective and Novocain quickly became the standard local anesthesia. Although its use has largely been replaced by lidocaine, it is still in use today, most frequently in dentistry. Einhorn was born in Hamburg, and due to the death of his parents his education took place in Leipzig with his relatives. He studied chemistry at the University of Leipzig and later at the University of Tübingen ...
In recent years our understanding of molecular mechanisms of drug action and interindividual variability in drug response has grown enormously. Meanwhile, the practice of anesthesiology has expanded to the preoperative environment and numerous locations outside the OR.

Hours of after-visit numbness may now be history!. Its here! For years, Dr. Brodil and I have talked about how great it would be if, after completing a procedure, we could make the numbness disappear. Well, we are now using a product that can indeed reverse the effects of a local anesthetic!. OraVerseTM is now available at our office. This is an agent that accelerates the return to normal sensation and function for patients who want to avoid the unwanted and unnecessary lingering soft tissue anesthesia (numbness) after routine dental procedures. The anesthetic we typically use contains vasoconstrictors (epinephrine). This part of the anesthetic produces prolonged loss of oral sensation and function. On average, it takes 3-5 hours to recover from soft tissue anesthesia, thus the hours of post-procedure numbness. With the administration of OraVerseTM, patients can return to normal sensation and function in about half that time.. There are no contraindications for OraVerseTM. In nationwide ...
You normally wont be allowed to eat or drink anything before having a general anaesthetic. This is because when you are under anaesthetic your bodys reflexes are temporarily stopped.

Johns notes that there has been a great deal of concern in recent years that anesthesia in infants and newborns may cause neurotoxicity leading to long-term cognitive problems and impaired learning. The data in rodents, primates and humans all point in this direction, and the Food and Drug Administration has just elevated its level of concern about this issue, he says. His research team is currently studying whether anesthetic interactions with PSD95 and other scaffolding proteins play a role. We hypothesized that because PSD95 is also involved in neuronal synapse formation - or making the proper connections between neurons as the brain is forming - during fetal and infant brain development, the ability of anesthetics to block the action of PSD scaffolding proteins, as shown in our new study, could also be preventing correct neuronal synapse development, leading to the long-term learning and memory deficits observed ...
The research team at the University of Rochester School of Medicine and Dentistry, led by Paul S. Brookes, Ph.D., and Keith Nehrke, Ph.D. found that a gene dubbed Slick (the technical name is KCNT2 or Slo 2.1) is required for anesthetic preconditioning to occur in mice. This gene is also found in humans and the team hypothesizes that it is necessary for the effective use of anesthetic preconditioning in people, too.. According to the National Center for Health Statistics, 395,000 CABG surgeries are performed every year. To initiate anesthetic preconditioning, a physician administers a specific type of anesthetic, called a volatile anesthetic, prior to the surgery. Some research suggests that volatile anesthetics help limit damage to the heart while it is temporarily stopped so the surgeon can perform the delicate bypass operation. But, the molecular mechanisms that underlie this process were previously unknown. Brookes, a professor of Anesthesiology, and Nehrke, a professor of Medicine, ...

1. Two homologous series of alkyl ureas, the n-alkyl and iso-alkyl homologs, have been tested on mice for the presence of anesthetic properties.. 2. All of these ureas, with the exception of the n-heptyl compound, which was too insoluble, were found to have anesthetic activity in varying degree.. 3. The anesthetic effects and toxicities increased with the molecular weight. The increase of the anesthetic effects was more rapid than that of the toxicities, thus the compounds of 4, 5 and 6 carbon atoms had the more favorable physiological indices.. ...

Chloroform was once a widely used anesthetic. On 4 November 1847, the Scottish obstetrician James Young Simpson first used the anaesthetic qualities of chloroform on a human,[12] two guests at his dinner party. This was done as an entertainment and not as a medical procedure. This was followed, only three days later, by the first use of chloroform on an actual patient, for a dental procedure, by Francis Brodie Imlach (1819-1891), also in Edinburgh, who, under other circumstances, may have gained the same fame as Simpson.[13] The use of chloroform during surgery expanded rapidly thereafter in Europe. In the 1850s, chloroform was used during the birth of Queen Victorias last two children.[14] In the United States, chloroform began to replace ether as an anesthetic at the beginning of the 20th century; however, it was quickly abandoned in favor of ether upon discovery of its toxicity, especially its tendency to cause fatal cardiac arrhythmia analogous to what is now termed sudden sniffers ...
