Ann Emerg Med 1994;24:1065-1073. As this agent is metabolized in the liver and its metabolites also have paralyzing properties, albeit to a lesser extent if not excreted by the kidneys, these metabolites can accumulate and sustain prolonged paralysis.49 In contrast to atracurium, vecuronium has less cardiovascular effects in asthmatic patients.56 In myasthenia gravis patients, the effects of both intermediate agents are similar, although slightly shorter recovery times occur with vecuronium.57, Atracurium is a bisquaternary ammonium benzyliso-quinilone.49 Hypotension secondary to histamine release occurs with this agent and can be avoided with slow infusion.49 Ester hydrolysis/atracurium is metabolized to non-active metabolites in the bloodstream and, therefore, is independent of end organ function (such as liver or kidney) for excretion of the metabolites.49 As a result, this drug is useful in patients with liver and kidney disease who require paralysis.

But you may receive extra oxygen through a mask or IV fluids through a catheter (tube) into a vein. It can diffuse into the lungs and may even displace oxygen, causing alveolar hypoxia.2,4 This is termed "diffusion hypoxia," which is rarely observed in clinical situations.4,8 In one study, using a 40% concentration of nitrous oxide in children with a nasal mask and monitored with pulse oximetry,8 it was concluded that 02 saturation never dropped significantly while using this mixture and returned to 100% post-treatment. Conscious sedation policy development and review. These rules are not only applicable to ED physicians but to medical support personnel.

If a patient’s level of consciousness is likely to improve after paralysis and intubation, concomitant use of sedation is imperative prior to paralyzing the patient. Only certain qualified health professionals can provide conscious sedation. ), In this regard, many scales are available to measure the degree of sedation, including the Ramsey Sedation scale, which ranks from 1-6 (anxious and agitated to no response to loud noise). Ann Emerg Med 1994;24:646-651.

Most agents used for reversal are competitive antagonists and can lull one into a false sense of security. Spontaneous recovery or evoked reversal of neuromuscular block. Most still do. 28. (d) For purposes of moderate sedation, drugs that are anesthetic agents (e.g., propofol, thiopental, methohexital, ketamine, etomidate, etc.) Patients suitable to undergo conscious sedation (CS) include those with moderate-severe anxiety, a swallow/gag reflex or a mild learning/physical disability such as cerebral palsy. In addition, oral ketamine, in doses up to 10 mg/kg is also effective for minor procedures.15 Nasal ketamine, 6 mg/kg for children 1-5 years of age also seems to provide adequate sedation.14 Ketamine is effective for sedation in asthmatic/COPD patients needing intubation, with or without paralyzing agents.9 The beneficial effects of ketamine on airway resistance permit its use in status asthmaticus even in the presence of acute myocardial infarction.9,16 It is usually administered in a IV drip form, 20 mg/h, after an initial bolus of 10 mg IV in adults. Conscious Sedation is a part of the dental treatment process which helps to establish a relaxed, easy and calm environment through the utilisation of sedative drugs.

The patient maintains the ability to respond purposely to verbal direction or verbal direction either alone or accompanied by light tactile stimulation. Deepika K, Bikhazi GB, Mikati HMJ, et al. Nitrous oxide is colorless and diffuses across membranes extremely rapidly.2,4 It is best given at a fixed ratio of 1:1 with 02 (50% concentration), although lower percentages are used in some prehospital protocols and dental offices.4,7 At higher altitudes (greater than 5280 ft.), its effectiveness decreases unless 70% nitrous oxide concentrations are used, which also increases its adverse effects. This provider will stay with you at all times during the procedure. These guidelines specifically apply to the level of sedation corresponding to moderate sedation/analgesia (previously called conscious sedation), which is defined as a drug-induced depression of consciousness during which patients respond purposefully † to verbal commands, either alone or accompanied by light tactile stimulation.
