The period of emergence from general anesthesia, where different elements of consciousness return at different rates.
A range of methods used to reduce pain and anxiety during dental procedures.
The act of BREATHING in.

Drugs administered before an anesthetic to decrease a patient's anxiety and control the effects of that anesthetic.
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.

John Collins Warren and his act of conscience: a brief narrative of the trial and triumph of a great surgeon. (1/916)

On examination of the correspondence among the principals involved, as well as the original patent application being prepared by Morton, it has become possible to reconstruct some of the remarkable details attending the first use of ether anesthesia at the Massachusetts General Hos pital in the autumn of 1846. At the time that Warren invited Morton to demonstrate the use of his "ethereal vapor" for anesthesia in a minor operation on Oct. 16, 1846, the exact chemical composition of the agent used was being held secret by Morton; Warren was clearly disturbed by this unethical use of a secret "nostrum." When the time arrived 3 weeks later for its possible use for a serious "capital" operation, Warren employed a simple stratagem of public confrontation to discover from Morton the true nature of the substance to be used. On being informed that it was pure unadulterated sulfuric ether, not some mysterious new discovery labeled "Letheon," Warren gave approval for its first use in a "capital" operation (low thigh amputation) on Nov. 7, 1846. Despite this revelation to the immediate participants, a veil of secrecy continued to surround the substance for many months, an anomalous situation evidently traceable to Morton's desire for personal reward from the discovery. It was this matter of secrecy, rather than priority for its discovery, that surrounded the early use of ether anesthesia with controversy and recrimination both in this country and abroad.  (+info)

Individualized feedback of volatile agent use reduces fresh gas flow rate, but fails to favorably affect agent choice. (3/916)

BACKGROUND: Cost reduction has become an important fiscal aim of many hospitals and anesthetic departments, despite its inherent limitations. Volatile anesthetic agents are some of the few drugs that are amenable to such treatment because fresh gas flow rate (FGFR) can be independent of patient volatile anesthetic agent requirement. METHODS: FGFR and drug use were recorded at the temporal midpoint of 2,031 general anesthetics during a 2-month preintervention period. Staff and residents were provided with their preintervention individual mean FGFR, their peer group mean, and educational material regarding volatile agent costs and low-flow anesthesia. FGFR and drug use were remeasured over a 2-month period (postintervention) immediately after this information (N = 2,242) and again 5 months later (delayed follow-up), for a further 2-month period (N = 2,056). RESULTS: For all cases, FGFR decreased from 2.4+/-1.1 to 1.8+/-1.0 l/min (26% reduction) after the intervention and increased to 1.9+/-1.1 l/min (5% increase of preintervention FGFR) at the time of delayed follow-up. Use of more expensive volatile agents (desflurane and sevoflurane) increased during the study period (P < 0.01). In a subgroup of 44 staff members with more than five cases in all study periods, 42 members decreased their mean FGFR after intervention. At delayed follow-up, 30 members had increased their FGFR above postintervention FGFR but below their initial FGFR. After accounting for other predictors of FGFR, the effectiveness of the intervention was significantly reduced at follow-up (28% reduction), but retained a significant effect compared to preintervention FGFR (19% reduction). CONCLUSIONS: Although individual feedback and education regarding volatile agent use was effective at reducing FGFR, effectiveness was reduced without continued feedback. Use of more expensive volatile agents was not reduced by education regarding drug cost, and actually increased.  (+info)

Effect of sevoflurane concentration on inhalation induction of anaesthesia in the elderly. (4/916)

We have conducted a randomized, double-blind comparison of 4% and 8% sevoflurane for induction of anaesthesia in unpremedicated patients aged more than 60 yr. Sevoflurane was inhaled in 50% nitrous oxide using a vital capacity breath technique, and mean, systolic and diastolic arterial pressures and heart rate were monitored continuously using a Finapres cuff. In the 8% sevoflurane group, time to successful laryngeal mask insertion was significantly shorter (mean 168 (SD 34) s vs 226 (62) s; P < 0.01) and achieved more often at the first attempt than in the 4% sevoflurane group. Arterial pressures were lower in the 8% group, but this was not significant. No patient had apnoea lasting longer than 1 min. A total of 69% of patients described induction as pleasant and 85% would choose to have it again. We conclude that compared with 8% sevoflurane, the use of 4% sevoflurane in the elderly resulted in greater cardiovascular stability but at the cost of prolonged and occasionally unsuccessful induction.  (+info)

The effect of pyrogen administration on sweating and vasoconstriction thresholds during desflurane anesthesia. (5/916)

BACKGROUND: General anesthetics increase the sweating-to-vasoconstriction interthreshold range (temperatures not triggering thermoregulatory defenses), whereas fever is believed to only increase the setpoint (target core temperature). However, no data characterize thresholds (temperatures triggering thermoregulatory defenses) during combined anesthesia and fever. Most likely, the combination produces an expanded interthreshold range around an elevated setpoint. The authors therefore tested the hypothesis that thermoregulatory response thresholds during the combination of fever and anesthesia are simply the linear combination of the thresholds resulting from each intervention alone. METHODS: The authors studied eight healthy male volunteers. Fever was induced on the appropriate days by intravenous injection of 30 IU/g human recombinant interleukin 2 (IL-2), followed 2 h later by an additional 70 IU/g. General anesthesia consisted of desflurane 0.6 minimum alveolar concentration (MAC). The volunteers were randomly assigned to the following groups: (1) control (no desflurane, no IL-2); (2) IL-2 alone; (3) desflurane alone; and (4) desflurane plus IL-2. During the fever plateau, volunteers were warmed until sweating was observed and then cooled to vasoconstriction. Sweating was evaluated from a ventilated capsule and vasoconstriction was quantified by volume plethysmography. The tympanic membrane temperatures triggering significant sweating and vasoconstriction identified the respective response thresholds. Data are presented as the mean +/- SD; P < 0.05 was considered significant. RESULTS: The interthreshold range was near 0.40 degrees C on both the control day and during IL-2 administration alone. On the IL-2 alone day, however, the interthreshold range was shifted to higher temperatures. The interthreshold range increased significantly during desflurane anesthesia to 1.9+/-0.6 degrees C. The interthreshold range during the combination of desflurane and IL-2 was 1.2+/-0.6 degrees C, which was significantly greater than on the control and IL-2 alone days. However, it was also significantly less than during desflurane alone. CONCLUSION: The combination of desflurane and IL-2 caused less thermoregulatory inhibition than would be expected based on the effects of either treatment alone. Fever-induced activation of the sympathetic nervous system may contribute by compensating for a fraction of the anesthetic-induced thermoregulatory impairment.  (+info)

Relative contribution of skin and core temperatures to vasoconstriction and shivering thresholds during isoflurane anesthesia. (6/916)

BACKGROUND: Thermoregulatory control is based on both skin and core temperatures. Skin temperature contributes approximately 20% to control of vasoconstriction and shivering in unanesthetized humans. However, this value has been used to arithmetically compensate for the cutaneous contribution to thermoregulatory control during anesthesia--although there was little basis for assuming that the relation was unchanged by anesthesia. It even remains unknown whether the relation between skin and core temperatures remains linear during anesthesia. We therefore tested the hypothesis that mean skin temperature contributes approximately 20% to control of vasoconstriction and shivering, and that the contribution is linear during general anesthesia. METHODS: Eight healthy male volunteers each participated on 3 separate days. On each day, they were anesthetized with 0.6 minimum alveolar concentrations of isoflurane. They then were assigned in random order to a mean skin temperature of 29, 31.5, or 34 degrees C. Their cores were subsequently cooled by central-venous administration of fluid at approximately 3 degrees C until vasoconstriction and shivering were detected. The relation between skin and core temperatures at the threshold for each response in each volunteer was determined by linear regression. The proportionality constant was then determined from the slope of this regression. These values were compared with those reported previously in similar but unanesthetized subjects. RESULTS: There was a linear relation between mean skin and core temperatures at the vasoconstriction and shivering thresholds in each volunteer: r2 = 0.98+/-0.02 for vasoconstriction, and 0.96+/-0.04 for shivering. The cutaneous contribution to thermoregulatory control, however, differed among the volunteers and was not necessarily the same for vasoconstriction and shivering in individual subjects. Overall, skin temperature contributed 21+/-8% to vasoconstriction, and 18+/-10% to shivering. These values did not differ significantly from those identified previously in unanesthetized volunteers: 20+/-6% and 19+/-8%, respectively. CONCLUSIONS: The results in anesthetized volunteers were virtually identical to those reported previously in unanesthetized subjects. In both cases, the cutaneous contribution to control of vasoconstriction and shivering was linear and near 20%. These data indicate that a proportionality constant of approximately 20% can be used to compensate for experimentally induced skin-temperature manipulations in anesthetized as well as unanesthetized subjects.  (+info)

Nasal sensory receptors responding to capsaicin, water and tactile stimuli in sevoflurane-anesthetized dogs. (7/916)

Responses of nasal receptors to capsaicin and water were studied from afferent recordings of the posterior nasal nerve (PNN) in 12 anesthetized dogs. Out of 12 non-respiration-modulated nasal receptors, 7 responded only to capsaicin, 3 responded to both water and capsaicin, and 2 to neither of them. All the fibers showed a rapid adaptation to mechanical probing of the nasal mucosa. These results indicate that the presence of sensory receptors responding to capsaicin and water are involved in PNN afferents of the dog.  (+info)

I.v. clonidine: does it work as a hypotensive agent with inhalation anaesthesia? (8/916)

In a double-blind, randomized, placebo-controlled study, 41 patients received clonidine 3 micrograms kg-1 or placebo at induction of isoflurane and nitrous oxide in oxygen anaesthesia. Metoprolol was also given to achieve a systolic arterial pressure of 80 mm Hg. Requirements for metoprolol were significantly less in the clonidine group (P < 0.00035), with no significant difference in mean arterial pressures over time. It would appear that clonidine is an i.v. hypotensive agent worthy of consideration, but data during the recovery period are required to comment further on the safety of this technique.  (+info)

Background As in inhaled isoflurane anesthesia, when isoflurane lipid emulsion (ILE; 8%, vol/vol) is intravenously administered, the primary elimination route is through the lungs. This study was designed to determine the minimum alveolar concentration (MAC) and the time course of washout of isoflurane for intravenously infused ILE by monitoring end-tidal isoflurane concentration. Methods Twelve healthy adult mongrel dogs were assigned randomly to an intravenous anesthesia group with 8% ILE or to an inhalation anesthesia group with isoflurane vapor. An up-and-down method and stimulation of tail clamping were used to determine MAC of 8% ILE by intravenous injection in the intravenous anesthesia group and MAC by the inhaled approach in the inhalation anesthesia group, respectively. Isoflurane concentration and partial pressure in end-tidal gas, femoral arterial blood, and jugular venous blood were measured simultaneously just before each tail clamping and during washout. Results The induction time ...

BACKGROUND: Ambulatory or outpatient anaesthesia is performed in patients who are discharged on the same day as their surgery. Perioperative complications such as postoperative nausea and vomiting (PONV), postoperative behavioural disturbances and cardiorespiratory complications should be minimized in ambulatory anaesthesia. The choice of anaesthetic agents and techniques can influence the occurrence of these complications and thus delay in discharge.. OBJECTIVES: The objective of this review was to evaluate the risk of complications (the risk of postoperative nausea and vomiting (PONV), admission or readmission to hospital, postoperative behavioural disturbances and perioperative respiratory and cardiovascular complications) and recovery times (time to discharge from recovery ward and time to discharge from hospital) comparing the use of intravenous to inhalational anaesthesia for paediatric outpatient surgery.. SEARCH METHODS: We searched the Cochrane Central Register of Controlled Trials ...
Approximately 25% of patients undergoing major surgery have known coronary artery disease (CAD) or risk factors for CAD.. N2O interferes with vitamin B12 and folate metabolism. This impairs production of methionine (from homocysteine), used to form tetrahydrofolate and thymidine during DNA synthesis. It has been repeatedly demonstrated that N2O anaesthesia increases postoperative homocysteine levels. Chronic hyperhomocysteinaemia is associated with cardiovascular disease, and acute hyperhomocysteinaemia is known to cause endothelial dysfunction. One small trial has demonstrated an increased incidence of postoperative myocardial ischaemia in patients receiving N2O anaesthesia. Reducing postoperative myocardial infarction and death are important aims for those with CAD undergoing major surgery.. Our previous trial (ENIGMA) studied 2050 patients and identified some serious adverse effects, but most patients were not at risk of CAD and so we could not reliably assess serious cardiac complications. ...

Propofol in exhaled breath can be measured and may provide a real-time estimate of plasma concentration. However, propofol is absorbed in plastic tubing, thus estimates may fail to reflect lung/blood concentration if expired gas is not extracted directly from the endotracheal tube.We evaluated exhaled propofol in five ventilated ICU patients who were sedated with propofol. Exhaled propofol was measured once per minute using ion mobility spectrometry. Exhaled air was sampled directly from the endotracheal tube and at the ventilator end of the expiratory side of the anesthetic circuit. The circuit was disconnected from the patient and propofol was washed out with a separate clean ventilator. Propofol molecules, which discharged from the expiratory portion of the breathing circuit, were measured for up to 60 h.We also determined whether propofol passes through the plastic of breathing circuits. A total of 984 data pairs (presented as median values, with 95% confidence interval), consisting of both ...

Author summary Currently we do not understand how anesthesia leads to loss of consciousness (LOC). One popular idea is that we loose consciousness when brain areas lose their ability to communicate with each other-as anesthetics might interrupt transmission on nerve fibers coupling them. This idea has been tested by measuring the amount of information transferred between brain areas, and taking this transfer to reflect the coupling itself. Yet, information that isnt available in the source area cant be transferred to a target. Hence, the decreases in information transfer could be related to less information being available in the source, rather than to a decoupling. We tested this possibility measuring the information available in source brain areas and found that it decreased under isoflurane anesthesia. In addition, a stronger decrease in source information lead to a stronger decrease of the information transfered. Thus, the input to the connection between brain areas determined the communicated

Every test offered in a pulmonary lab depends in one way or another on one simple measurement - volume. Whether it is expressed in liters or as ventilation, a pulmonary diagnostic system must first get volume measurements correct. The Stead-Wells Spirometer has long been recognized as the Gold Standard for volumetric measurements. It also provides a near zero resistant breathing circuit for FRC and DLCO measurements. It eliminates the need for high resistance demand valves found on flow based systems. MICRO GA ...

Many people think that Vaporizers will be the identical to mods, but theyre not. They are different because rather than changing your ordinary batteries to a robust vaporizer, you put in a tang to it. Vapers use tanks to be able to breathe and inhale pure nicotine while keeping their hands off the flames and smoke. Theyre also different for the reason that instead of changing batteries or connecting the two pieces of equipment together, the paper uses his tongue to suck in the liquid like a straw. Both these Vaporizer mods utilize the same components: the coil, the post that holds the wick, and a regulated box mod. One has a temperature control, another includes a battery life indicator and the ability to adjust the wattage and the voltage. The only real difference is that the regulated box mod has the ability to change the temperature at which the wick burns. Thats what gives it the ability to regulate your temperature and give you the kind of vaporized flavor you need. There are a number of ...
