• An allergic reaction (can also reveal how severe the reaction is)
• Infection
• You develop any new symptoms.
• What drugs your child is taking
• Washing of the skin (irrigation) -- perhaps every few hours for several days
• Males age 14 and older: 150 mcg/day
• Number of filtering units (nephrons) decreases. Nephrons filter waste material from the blood.
• Two to three 8 oz. cups of brewed or drip coffee (about 200 to 300 mg of caffeine) per day and 5 servings of caffeinated soft drinks or tea is an average or moderate amount of caffeine for most people. (However, it should be noted that 5 servings of regular soft drinks is over 700 calories and can contribute to obesity.)
• Use of water pills called loop diuretics

When propofol is used for sedation in an intensive care unit, observe for lack of agitation and movement, tolerance of me- chanical ventilation, and arousability for neurologic assessment when drug dosage is reduced by slowing the IV infusion rate. When a neuromuscular blocking agent is used in an inten- sive care unit, observe for tolerance of mechanical ventilation. Observe for adverse effects Serious adverse effects are most likely to occur during and within a few hours after general anesthesia and major surgery. The nurse observes for adverse effects in the preanesthetic and postanesthetic periods. The often-used combination of an opioid analgesic and a sedative- type drug produces additive CNS depression. After general anesthesia and during propofol administration in intensive care units, observe for: (1) Excessive sedation—delayed awakening, failure to re- the early recovery period is normally marked by a progressive spond to verbal or tactile stimuli increase in alertness, responsiveness, and movement. Hypoxia and hypercarbia indicate inadequate ventilation and may result from depression of the respiratory center in the medulla oblongata, prolonged paraly- sis of respiratory muscles with muscle relaxant drugs, or retention of respiratory tract secretions due to a depressed cough reflex. Extreme changes must be balances reported to the surgeon or the anesthesiologist. These problems are most likely to occur while general anesthesia is being administered and progressively less likely as the patient recovers or awakens. Restlessness may be caused by the anesthetic, pain, or hypoxia With ketamine, unpleasant dreams or hallucinations also and should be assessed carefully before action is taken. After regional anesthesia, observe for: (1) CNS stimulation at first (hyperactivity, excitement, These symptoms are more likely to occur with large doses, high seizure activity) followed by CNS depression concentrations, injections into highly vascular areas, or accidental injection into a blood vessel. Doses used for spinal or epidural anesthesia usually have little effect on cardiovascular function. Urinary retention may occur in anyone but is more likely in older men with enlarged prostate glands. Observe for drug interactions For interactions involving preanesthetic medications, see Anti- anxiety and Sedative-Hypnotics Drugs (Chap. Drugs that increase effects of general anesthetic agents: (1) Antibiotics—aminoglycosides (gentamicin and related These antibiotics inhibit neuromuscular transmission. When they drugs) are combined with general anesthetics, additive muscle relaxation occurs with increased likelihood of respiratory paralysis and apnea. Halothane and a few norepinephrine rarely used general anesthetics sensitize the myocardium to the effects of catecholamines. If they are combined, ventricular tachy- cardia or ventricular fibrillation may occur. Some are used therapeutically for their barbiturates, opioid analgesics, sedative-hypnotics CNS depressant effects; others are used mainly for other purposes, and CNS depression is a side effect. Any combination of these drugs with each other or with general anesthetic agents produces additive CNS depression.
