Congenital or acquired disorders of the pediatric airway can affect the upper, lower, or entire airway. There are fundamental differences between the anatomy and physiology of the neonate, pediatric, and adult airways. Infants are not merely small adults in this respect and size, surface area, proportion, resistance, and compliance vary greatly between the age groups. A clear understanding of these significant differences and how they affect patients dependent on age is key to appropriate management.

NCBI Bookshelf. The pediatric population often responds to drugs and other therapeutics differently than adults do. Generally, the guidelines that practitioners use when they prescribe drugs have not been based on biologic or pharmacologic principles when they extrapolate the drug doses used for adults to infants and children. Not only have the guidelines tended to be simplistic in that they assume a linear relationship between children and adults, but they have also not made allowances for the complex changes in growth and development that take place during childhood. A number of quantitative and qualitative differences in the anatomy and physiology of the infant and developing child can affect the absorption, distribution, metabolism, and excretion of various drugs and other xenobiotic compounds. Additionally, children differ from adults not only in anatomical and physiological ways but also in the types of diseases from which they suffer and in the manifestations of those diseases that they do have in common with adults. These factors can determine the types of therapies developed for children as well as the design of studies that evaluate new therapeutic agents.

Basics pp Cite as. Pediatric anesthesia involves patients ranging from preterm infants to teenagers, and these groups require different anesthetic equipment and techniques. Successful and safe anesthetic management in pediatric patients depends on an appreciation and clear understanding of the physiological, anatomic, pharmacological and psychological differences among the pediatric age groups and between pediatric and adult patients. Changes in the airways, cardiovascular system, renal function, central and autonomic nervous system, gastrointestinal system and thermoregulation that take place during development make anesthetic management different and extremely challenging. Pediatric anesthesia management requires an understanding and knowledge of the differences and characteristics unique to the child and infant. Infants and children have unique anatomic, physiological, pharmacological, and psychological issues relating to perioperative management [1].

As the lungs expand and contract, oxygen rich air is inhaled and carbon dioxide is removed. Breathing begins at the mouth and nose where air is inhaled. The air travels to the back of the throat, into the trachea and then divides into the passages known as the bronchial tubes. The bronchial tubes continue to divide as the go deeper into the lungs and the air is carried to the alveoli. Oxygen passes through the walls of the alveoli and into the blood vessels that surround these tiny sacs. Once oxygen enters the blood vessels, it is carried out of the lungs and to the heart where it can be pumped throughout the body to other organs and tissue.

The second in a series of four volumes dealing with the question of growth and development concerns itself with the anatomy and physiology of the whole body. The authors are leaders in their respective branches, and this fact bespeaks the scientific thoroughness with which the book is written. The nervous system is dealt with as follows: the general development; the histogenesis of the cerebral cortex; cranial topography in childhood; the spinal cord; myelinization of the nerve fibers and their functions; the development of reflex behavior; the development of the centers in the spinal cord and the brain; the nerve centers; the visual mechanism; the internal and the middle ear, and the glands of internal secretion.

Anatomy and Physiology in Neonates and Children

General and central nervous system anatomy and physiology in children is different to that of adults and this is relevant to traumatic brain injury TBI and spinal cord injury. The controversies and uncertainties in adult neurotrauma are magnified by these differences, the lack of normative data for children, the scarcity of pediatric studies, and inappropriate generalization from adult studies. Cerebral metabolism develops rapidly in the early years, driven by cortical development, synaptogenesis, and rapid myelination, followed by equally dramatic changes in baseline and stimulated cerebral blood flow.

The infant and child differ structurally from the adult in a number of ways which are critical to the design for protection against impact forces and for adequate occupant restraint systems. The purpose of this paper is to bring together a profile of the anatomy, anthropometry, growth and development of the infant and child. Age differences related to the proper design of child restraint systems are emphasized. Problems discussed include child--adult structural differences, center of gravity of the body, the head mass in relation to the neck and general body proportions, positions of key organs, and biomechanical properties of tissues. Infants and children are not miniature adults.

The American Academy of Pediatrics recommends people be under pediatric care through the age of 21 [1] [2] though usually only minors are required to be under pediatric care. In the United Kingdom , pediatrics covers patients until age Pediatricians work in hospitals and children's hospitals particularly those working in its subspecialties e.

Except where otherwise stated, drug dosages and recommendations are for the non-pregnant adult who is not breastfeeding. We develop from a small mass of undifferentiated cells to a highly complex organism that is the adult human. Various systems develop and mature at different rates and these differences affect anaesthesia care. The neonate undergoes a rapid period of growth and development continuing into the first few years of life.
