Abstract

CHILDREN ARE NOT SMALL ADULTS. In this chapter, we will discuss the resources and standards that must be in place, in order for community-based programs to be in a position to deliver quality anesthetic care to children. Patient and procedural selection policies, appropriate equipment, dedicated physical space, and knowledgeable and experienced providers are just some of what is required. Caring for children in a large children’s hospital, where the entire system is geared toward pediatrics, can test the most experienced pediatric anesthesiologist. Children have unique physiologic, pharmacologic, pathophysiology, and behavioral characteristics which change and develop throughout their lives. We will examine the pre-operative, intra-operative, and post-operative aspects that make pediatric anesthesia different from the perioperative care of adults.

INTRODUCTION

Children are not small adults. Pediatric patients greatly vary from 1000 gram premature infants to the morbidly obese adolescents, and each one presents a special set of challenges to the anesthesiologists who care for them.

These patients have unique physiologic, pharmacologic, pathophysiology, and behavioral characteristics which change and develop throughout their lives. Caring for children in a large children’s hospital, where the entire system is geared toward pediatrics, can test the most experienced pediatric anesthesiologist. When these patients present to community based centers, with fewer resources and personnel focused on children, these challenges can be overwhelming and possibly compromise safe, quality pediatric anesthesia.

In this chapter, we will discuss the resources and standards that must be in place, in order for community-based programs to be in a position to deliver quality anesthetic care to children. Patient and procedural selection policies, appropriate equipment, dedicated physical space, and knowledgeable and experienced providers, are just some of what is required of institutions which desire to care for pediatric anesthesia patients. We will examine the pre-operative, intra-operative, and post-operative aspects that make pediatric anesthesia different from the perioperative care of adults. Additionally, we will provide an overview of the anesthetic management of some of the more common ambulatory pediatric procedures which may be encountered in the community based practice.

PATIENT AND PROCEDURE SELECTION

Current evidence has established that some children have a higher risk of perioperative morbidity and mortality. Specifically, neonates, critically ill children, and children with complex comorbidities may benefit from care delivered in specialized hospitals. However, historically, American Society of Anesthesiologists (ASA) classification 1 and 2 children have been safely cared for in community based hospitals and surgical centers. Community-based centers caring for children must develop, administer, and maintain a system that allows for the “correct” pediatric patients to be anesthetized by a dedicated group of anesthesia and surgical providers focused on providing safe and effective care for pediatric patients.

Routine pediatric surgeries are performed in several types of institutions (i.e. children’s hospitals, adult hospitals, ambulatory surgery centers, etc.). The vast majority of pediatric surgical procedures are completed in an outpatient setting with an increasing number occurring in freestanding locations [1, 2]. Table 1 lists the most common Ambulatory procedures on patients younger than 15 years of age.

Despite the establishment and maturation of pediatric surgery as a subspecialty, approximately 40% of the most common pediatric inpatient surgical procedures are performed in non-pediatric hospitals [4]. However, complex pediatric surgeries are 6-16 times more common in a pediatric hospital than any other institution [5]. Table 2 lists the most common inpatient pediatric surgery procedures.

In 2014, a Task Force for Children’s Surgical Care established guidelines for providing a “surgical and anesthetizing” level of care to pediatric patients undergoing surgical procedures. The purpose of center classification was to assure optimal resources to care for infants and children undergoing surgical intervention and to define the procedures and patients that are within the typical scope of practice of each level [6]. A summary of the Children’s Surgical Center Standard and Scope of Practice are reviewed in Table 3.

These recommendations have been endorsed by the board of the Society for Pediatric Anesthesia (SPA) and the American College of Surgeons (ACS). How these standards will impact pediatric care remains to be seen. Suffice it to say, that the needs to anesthetize children in community-based settings is only increasing and will require greater cooperative planning to facilitate safe and effective regional care.

Resources Necessary for the Perioperative Care of Children

Equipment

Prior to anesthetizing an infant or child, a comprehensive selection of pediatric equipment that is regularly stocked and maintained must be readily available to the anesthesiology care team (Table 4). Airway equipment and intravenous catheters are manufactured in various sizes to meet the needs of children of all ages. In addition, emergency drugs and equipment including, a code cart with pediatric defibrillator pads and medications for resuscitation and malignant hyperthermia, and a difficult airway cart all need to be immediately accessible [7, 8]. Resuscitation drugs should be stocked in appropriate infant/pediatric concentrations. Furthermore, even if the entire perioperative staff is well educated on pediatric emergency drug dosing and administration, it is prudent to have a clearly written pediatric dose schedule for these drugs easily accessible [8, 9].

Monitors

Vigilant monitoring of patients under anesthesia significantly improves perioperative morbidity and mortality. While properly trained, expe...
