Other narcotics antiviral genes discount zovirax 400 mg on-line, such as meperidine and levorphanol typical timeline hiv infection discount zovirax master card, are effective for the treatment of moderate to hiv infection rates by continent order zovirax with a visa severe pain. For mild to moderate pain, the primary health care provider may order a narcotic such as codeine or pentazocine. In addition to the relief or management of moderate to severe acute and chronic pain, the narcotic analgesics may be used for the following reasons: · To lessen anxiety and sedate the patient before surgery. It is a mu opioid agonist with rapid onset, peak effect, and short duration of action. The mixed agonist-antagonist drugs act on the mu receptors by competing with other substances at the mu receptor (antagonist activity) and are agonists at other receptors. The actions of the narcotic analgesics on the various organs and structures of the body (also called secondary pharmacological effects) are shown in Display 19-1. Levomethadyl is given in an opiate dependency clinic to maintain control over the delivery of the drug. Because of its potential for serious and life-threatening proarrhythmic effects, levomethadyl is reserved for use in the treatment of addicted patients who have no response to other treatments. Levomethadyl is not taken daily; the drug is administered three times a week (Monday/Wednesday/Thursday or Tuesday/Thursday/ Saturday). The ability of a narcotic analgesic to relieve pain depends on several factors, such as the drug, the dose, the route of administration, the type of pain, the patient, and the length of time the drug has been administered. Morphine is the most widely used opioid and an effective drug for Nursing Alert If transferring from levomethadyl to methadone, the nurse should wait 48 hours after the last dose of levomethadyl before administering the first dose of methadone or other narcotic. Detoxification involves withdrawing the patient from the narcotic while preventing withdrawal symptoms. The dosages used vary with the patient, the length of time the individual has been addicted, and the average amount of drug used each day. Patients enrolled in an outpatient methadone program for detoxification or maintenance therapy on methadone must continue to receive methadone when hospitalized. All narcotic analgesics are contraindicated in patients with known hypersensitivity to the drugs. These drugs are contraindicated in patients with acute bronchial asthma, emphysema, or upper airway obstruction and in patients with head injury or increased intracranial pressure. The drugs are also contraindicated in patients with convulsive disorders, severe renal or hepatic dysfunction, acute ulcerative colitis, and increased intracranial pressure. The narcotic analgesics are Pregnancy Category C drugs (oxycodone, Category B) and are not recommended for use during pregnancy or labor (may prolong labor or cause respiration depression of the neonate). The use of narcotic analgesics is recommended during pregnancy only if the benefit to the mother outweighs the potential harm to the fetus. Agonists One of the major hazards of narcotic administration is respiratory depression, with a decrease in the respiratory rate and depth. The most common adverse reactions include light-headedness, dizziness, sedation, constipation, anorexia, nausea, vomiting, and sweating. When these effects occur, the primary health care provider may lower the dose in an effort to eliminate or decrease the intensity of the adverse reaction. The obese must be monitored closely for respiratory depression while taking the narcotic analgesics. The drug is used cautiously during lactation (wait at least 4 to 6 hours after taking the drug to breastfeed the infant). The narcotics are used cautiously in patients undergoing biliary surgery because the drug may cause spasm of the sphincter of Oddi. Patients taking the agonist-antagonist narcotic analgesics may experience withdrawal symptoms if the patient has been abusing or using narcotics. The agonist-antagonists drugs can cause opioid withdrawal symptoms in those who are physically dependent on the opioids. Passion flower is often used in combination with other herbs, such a valerian, chamomile, and hops, for promoting relaxation, rest, and sleep. Passion flower contains coumarin, and the risk of bleeding may be increased when used in patients taking warfarin and passion flower. This is especially important when a narcotic is given for the first time because data may be obtained during the initial history and physical assessment that require the nurse to contact the primary health care provider. For example, the patient may state that nausea and vomiting occurred when he or she was given a drug for pain several years ago. Further questioning of the patient is necessary because this information may influence the primary health care provider regarding administration of a specific narcotic drug.
Reflexes hiv infection needle stick cheap 200 mg zovirax visa, such as the swallowing and gag reflexes anti viral conjunctivitis generic zovirax 400 mg visa, are lost during deep general anesthesia antiviral spray zovirax 200mg visa. An anesthesiologist is a physician with special training in administering anesthesia. A nurse anesthetist is a nurse with special training who is qualified to administer anesthetics. A Topical Anesthesia Topical anesthesia involves the application of the anesthetic to the surface of the skin, open area, or mucous membrane. This type of anesthesia may be used to desensitize the skin or mucous membrane to the injection of a deeper local anesthetic. Local Infiltration Anesthesia Local infiltration anesthesia is the injection of a local anesthetic drug into tissues. This type of anesthesia may be used for dental procedures, the suturing of small wounds, or making an incision into a small area, such as that required for removing a superficial piece of tissue for biopsy. The anesthetized area is usually larger than the area affected by 317 the various methods of administering a local anesthetic include topical application, local infiltration, or regional anesthesia. Preparing the Patient for Local Anesthesia Depending on the procedure performed, preparing the patient for local anesthesia may or may not be similar to preparing the patient for general anesthesia. Other local anesthetic procedures may require the patient to be in a fasting state because a sedative may also be administered. The nurse may administer an intravenous sedative such as the antianxiety drug diazepam (Valium) (see Chap. Spinal Anesthesia Spinal anesthesia is a type of regional anesthesia that involves the injection of a local anesthetic drug into the subarachnoid space of the spinal cord, usually at the level of the second lumbar vertebra. There is a loss of feeling (anesthesia) and movement in the lower extremities, lower abdomen, and perineum. Conduction Blocks A conduction block is a type of regional anesthesia produced by injection of a local anesthetic drug into or near a nerve trunk. Examples of a conduction block include an epidural block (injection of a local anesthetic into the space surrounding the dura of the spinal cord); a transsacral (caudal) block (injection of a local anesthetic into the epidural space at the level of the sacrococcygeal notch); and brachial plexus block (injection of a local anesthetic into the brachial plexus). Administering Local Anesthesia the physician or dentist administers a local injectable anesthetic. Gerontologic Alert Preanesthetic drugs may be omitted in those 60 years or older because many of the medical disorders for which these drugs are contraindicated are seen in older individuals. For example, atropine and glycopyrrolate, drugs that can be used to decrease secretions of the upper respiratory tract, are contraindicated in certain medical disorders, such as prostatic hypertrophy, glaucoma, and myocardial ischemia. Nursing Responsibilities When Caring for a Patient Receiving Local Anesthesia When applicable, the nurse may be responsible for applying a dressing to the area. Depending on the reason for using local anesthesia, the nurse also may be responsible for observing the area for bleeding, oozing, or other problems after the administration of the anesthetic. Selection of Preanesthetic Drugs the preanesthetic drug is usually selected by the anesthesiologist and may consist of one or more drugs (Table 35-2). The nurse usually gives a preanesthetic drug before the administration of general anesthesia but on occasion may give it before injection of the local anesthetic to sedate the patient. The more specific purposes of these drugs include the following: Narcotics droperidol fentanyl meperidine hydrochloride morphine sulfate Barbiturates pentobarbital secobarbital Cholinergic-Blocking Drugs atropine sulfate glycopyrrolate scopolamine Inapsine Sublimaze, generic Demerol, generic Duramorph, generic Nembutal Sodium, generic generic generic Robinul, generic generic · Narcotic or antianxiety drug-to decrease anxiety and apprehension immediately before surgery. The patient who is calm and relaxed can be anesthetized more quickly, usually requires a smaller dose of an induction drug, may require less anesthesia during surgery, and may have a smoother anesthesia recovery period (awakening from anesthesia). Some anesthetic gases and volatile liquids are irritating to the lining of the respiratory tract and thereby increase mucous secretions. The cough and swallowing reflexes are lost during general anesthesia, and excessive secretions can pool in the lungs, resulting in pneumonia or atelectasis during the postoperative period. The Antianxiety Drugs With Antiemetic Properties hydroxyzine Atarax, Vistaril, generic Antianxiety Drugs chlordiazepoxide diazepam midazolam Librium, generic Valium, generic Versed *The term generic indicates the drug is available in generic form. Barbiturates are used only occasionally; narcotics are usually preferred for sedation. Scopolamine and glycopyrrolate also have mild sedative properties, and atropine may or may not produce some sedation.

The pronator quadratus is more active regardless of forearm position antiviral compounds buy cheap zovirax 200 mg, whether the activity is slow or fast or working against a resistance or not hiv infection among youth generic 200 mg zovirax. The pronator teres is called on to hiv infection through blood transfusion 200 mg zovirax with amex become more active when the pronation action becomes rapid or against a high load. The final muscle group at the elbow is the extensor supinator muscles originating on the lateral epicondyle, which includes the supinator and three wrist muscles (extensor carpi ulnaris, extensor carpi radialis longus, and extensor carpi radialis brevis). Supination is produced by the supinator muscle and by the biceps brachii under special circumstances. The supinator is the only muscle that contributes to a slow, unresisted supination action in all forearm positions. The biceps brachii can supinate during rapid or rested movements when the elbow is flexed. The flexion action of the biceps brachii is neutralized by actions from the triceps brachii, allowing contribution to the supination action. Many of the muscles acting at the elbow joint create multiple movements, and a large number of two-joint muscles also generate movements at two joints. Where an isolated movement is desired, synergistic actions are required to neutralize the unwanted action. For example, the biceps brachii flexes the elbow and supinates the radioulnar joint. To provide a supination movement without flexion, synergistic action from an elbow extensor must occur. Likewise, if flexion is the desired movement, a supination synergist must be recruited. Another example is the biceps brachii action at the shoulder joint where it generates shoulder flexion. To eliminate a shoulder movement during elbow flexion, there must be action from the shoulder extensors. A final example is the triceps brachii action at the shoulder where it creates shoulder extension. If a strong extension is required at the elbow in pushing and throwing actions, shoulder flexors must be engaged to eliminate the shoulder extension movement. If an adjacent joint is to remain stationary, appropriate changes in muscle activity must occur and are usually proportional to the velocity of the movement (26). The joint forces created by a maximum isometric flexion in an extended position that is equal to approximately two times body weight. The semiprone elbow position is the position at which maximum strength in flexion can be developed, followed by the supine position, and finally, the pronated position (62). The supine position generates about 20% to 25% more strength than the pronation position. Semiprone flexion exercises should be included in a conditioning routine to take advantage of the strong position of the forearm. This is a common forearm position for daily living activities and for power positions in upper extremity sport skills. Finally, pronation and supination strength is greatest in the semiprone position, with the torque dropping off considerably at the fully pronated or fully supinated position. In stretching the muscles, the only positions putting any form of stretch on the flexors and extensors must incorporate some hyperextension and flexion at the shoulder joints. Stretching these muscles while the arm is in the neutral position is almost impossible because of the bony restrictions to the range of motion. The forearm position in which the flexors and extensors are the strongest is semiprone. For the flexors specifically, the biceps brachii can be brought more or less into the exercise by supinating or pronating, respectively. Numerous exercises are available for both the flexors and extensors; examples of which are provided in Figure 5-22.
