An osteotomy is performed with a curved chisel at the docrinological, cardiovascular, or pulmonary comorbidi- base of the spinous processes of the vertebrae above and below the ties [7, 20, 22]. We third of the upper laminae and the upper third of the lower laminae describe two less invasive techniques which appear inter- are resected using Kerrison rongeurs of varying widths and lengths. With the other hand, the Kerrison rongeurs are used to remove larly in the elderly.

The facet and lamina roof decompressions create a portal tendency towards less invasive decompressive surgery has by which the neural foramina can be decompressed by means of an extralong (30-cm) Kerrison rongeur. The adequacy of decompres- emerged as a logical surgical treatment alternative, spar- sion is checked with foraminal probes. Stenosis in the elderly is due mainly teotomized spinous processes regain their initial positions by rest- to a combination of facet hypertrophy and soft tissue buck- ing on the remainder of the neural arches. Both the lumbar fascia and the subcutaneous tissue and skin are closed in a standard fash- ling. One such procedure, laminarthrectomy, refers to a surgi- cal decompression involving a partial laminectomy of the logical finding or diagnosis.

CHAPTER 4 NURSING PROCESS IN DRUG THERAPY 61 Neonates, Infants, and Children: Physiologic Characteristics and TABLE 4–2 Pharmacokinetic Consequences Physiologic Characteristics Pharmacokinetic Consequences Increased thinness and permeability of skin in Increased absorption of topical drugs (eg, corticosteroids may be absorbed sufﬁciently to neonates and infants suppress adrenocortical function) Immature blood–brain barrier in neonates Increased distribution of drugs into the central nervous system because myelinization and infants (which creates the blood–brain barrier to the passage of drugs) is not mature until approximately 2 years of age Increased percentage of body water (70% Usually increased volume of distribution in infants and young children, compared with to 80% in neonates and infants, compared with adults. However, prolonged drug 50% to 60% in children older than 2 years of half-life and decreased rate of drug clearance may offset. Altered protein binding until approximately 1 year the amount and binding capacity of plasma proteins may be reduced. This may result in of age, when it reaches adult levels a greater proportion of unbound or pharmacologically active drug and greater risks of adverse drug effects. Drugs with decreased protein binding in neonates, compared with older children and adults, include ampicillin (Omnipen, others), diazepam (Valium), digoxin (Lanoxin), Iidocaine (Xylocaine), nafcillin (Unipen), phenobarbital, phenytoin (Dilantin), salicylates (eg, aspirin), and theophylline (Theolair). Decreased glomerular ﬁltration rate in neonates In neonates and infants, slowed excretion of drugs eliminated by the kidneys. Decreased activity of liver drug-metabolizing Decreased capacity for biotransformation of drugs. This results in slowed metabolism and enzyme systems in neonates and infants elimination, with increased risks of drug accumulation and adverse effects. Increased activity of liver drug-metabolizing Increased capacity for biotransformation of some drugs. This results in a rapid rate of enzyme systems in children metabolism and elimination. For example, theophylline is cleared about 30% faster in a 7-year-old child than in an adult and approximately four times faster than in a neonate. In addition, adverse effects are likely because of physiologic changes associated with aging (Table 4–3), patho- Body surface area (in square meters) logic changes due to disease processes, multiple drug therapy 1.
