Table 43-7 Fasting Guidelines for Children Requiring Elective Anesthesia184 The risk of regurgitation and aspiration in children who present for emergency surgery is far more difficult to assess 10 mg maxalt with amex. Several factors relate to this risk including the severity and nature of the trauma order maxalt on line amex, existing medical conditions, drugs that were administered, and the timing and nature of the foods ingested. The only evidence upon which to assess the risk of a full stomach relates to the interval between the last food ingested and the trauma or injury. There is no evidence in children that administration of a prokinetic drug empties the stomach after trauma. Auscultation of bowel sounds in the abdomen does not ensure gastric emptying, although passing gas does imply peristalsis of the small and large bowels is present but does not ensure return of gastric motility. We consider children who ingested solid foods within 8 hours of a trauma to be at risk for regurgitation and aspiration and take appropriate precautions for managing the airway. Although diabetes mellitus delays gastric emptying, this may require years before the gastroparesis develops. Laboratory Testing 3070 Preoperative laboratory testing is infrequently ordered in healthy children without a pre-existing medical condition. A preoperative hemoglobin is indicated in those who are at risk for massive bleeding, those with pre- existing anemia in whom bleeding is highly probable, those with chronic nutritional deficiency, and those with sickle cell disease (see later). A preoperative pregnancy test is required before anesthesia and sedation in most children of childbearing years in most jurisdictions. The reason for this test is the risk that some drugs that are administered in the perioperative period may cause a miscarriage or, less likely, teratogenicity of an unborn fetus. The former test yields more rapid results, is cheaper but has a false-negative rate early after conception. Many institutions and states require preoperative pregnancy testing in females who have reached menarche; some require testing in all females who are older than a specific age. If the pregnancy test is positive and the surgery is elective, the results must be conveyed to the patient. Due consideration should be given to the risk that anesthesia and surgery might pose to the unborn fetus if surgery proceeds. If, however, the surgery is emergent, then the risk benefit ratio of proceeding must be carefully assessed. Additional factors that increase the risk of adverse airway events include cigarette smoking in the house, atopy, asthma, prematurity, young age, and secretions. Care must be taken to use a dilute solution of neosynephrine, as concentrated solutions may cause a hypertensive crisis. We prefer to manage these children with a face mask if possible in order to minimize the risk of triggering airway reflex responses. However, if the airway must be manipulated, a supraglottic airway is less likely to trigger airway reflex responses than a tracheal tube. Asthma Up to 20% of children have asthma or an asthmatic history, but many fewer present with severe asthma that may complicate anesthesia. In the preoperative assessment, the age of onset of asthma, number and date of the most recent hospital admissions for asthma, treatment (β -agonists or steroids by2 inhalation), and current state of asthma should be recorded. Most children with asthma have never been admitted to hospital because of their asthma. If oral steroids have been prescribed recently for an acute exacerbation of asthma, careful preoperative examination of the chest must be performed to ensure that there is no lingering reactive airway component. On the morning of the surgery, the child’s lungs should be examined to check for wheezing. If wheezing is present, the child should be instructed to cough deeply to clear any airway secretions present, and bronchodilator therapy should be initiated. Preoperative bronchodilator therapy should be administered to children with mild to moderate asthma even if they are not wheezing, as this reduces airway resistance by approximately 25% during sevoflurane anesthesia and 3072 tracheal intubation. Preoperative bronchodilator therapy should be administered to children who are wheezing and present for emergency or urgent nonairway surgery. Equipment should be prepared to administer intraoperative bronchodilator therapy should the need arise. In these cases, the diagnosis is made “clinically” by the presence of loud snoring, witnessed apneas, nocturnal enuresis, attention deficit disorder and behavioral problems, and inability to concentrate in school or poor school performance. In contrast to general anesthesia, regional anesthesia does not increase the risk of perioperative apnea and does not require perioperative monitoring, unless the infant also received sedation, has multisystem disease, or has a history of perioperative apneas. If the parents have an apnea monitor at home and have been trained to manage apnea, the child may be discharged home in the parents’ care. If the child is anxious, he/she should be premedicated with oral midazolam (see later) in a dose appropriate for the child’s age. A trigger-free anesthetic includes propofol, opioids, benzodiazepines, nondepolarizing muscle relaxants, nitrous oxide, and regional anesthesia. The initial dose should maintain blood concentrations of dantrolene (>3 μg/mL) for 6 hours, after which its elimination half-life is 10 hours (Fig. This is sufficient dantrolene in a single vial for a loading dose in a 100 kg patient, far more dantrolene than is needed to treat the initial reaction in a child. If dantrolene is administered, a urinary catheter may be indicated depending on the dantrolene formulation used. There is a host of additional strategies that may be used to stabilize the child including cooling strategies, and antiarrhythmics. Becker dystrophy is a milder form of the disease with an onset in the second decade of life. Emery–Dreifuss syndrome is also a milder form of the disease often presenting with cardiac conduction defects, with syncope as the presenting finding. The dystrophin protein complex is essential for the stability of the cytoskeleton of muscles. The administration of an inhalational anesthetic (halothane > sevoflurane > isoflurane) as well as succinylcholine may cause skeletal muscle contractions, damaging membranes and releasing intracellular contents. Mitochondrial myopathies are a complex group of disorders that result from defects in the protein complexes of the respiratory chain in mitochondria. Vaso-occlusive crises may involve a number of areas including bone, chest, and brain. Some children suffer from repeated vaso-occlusive crises whereas others never experience them. These crises are not related to hypoxia, hypovolemia, or hypothermia, but rather to a systemic inflammatory response, the nature of which remains unclear. This disorder presents few problems during routine general and regional anesthesia and surgery provided extreme conditions, such as hypothermia and cardiopulmonary bypass, are not employed. Preoperatively, a history of the frequency, severity, and precipitating triggers of sickle and vaso-occlusive crises in the child should be elicited. Consultation with the treating hematologist should provide insight into the current local strategies for managing this patient. The sickledex test is unreliable in infants under 6 months of age because Hb F interferes with the sickling process and renders the test nonconfirmatory. Infants under 6 months of age rarely sickle because of the presence of Hb F, which gradually wanes in concentration beyond 3 months of age. If the test is positive or if the child is suspected of having sickle hemoglobin from history, then a hemoglobin electrophoresis should be performed to identify the particular hemoglobinopathy that is present. Optimal management of these children includes maintaining neutral thermoregulation and adequate hydration and oxygenation throughout the perioperative period. Understanding the pathophysiology of the disease enables the clinician to anticipate complications and prepare the anesthetic to avoid them. In children, anesthesia is usually required to delimit the extent of and tumor effects on mediastinal structures in radiology as well as for tissue biopsy and chronic chemotherapy access in the operating room. The decision to proceed with local, regional, or general anesthesia depends on the age and level of cooperation of the child, the extent of mediastinal organ compromise, and the accessibility of the node or tumor being biopsied. A multidisciplinary team that includes the surgeon, anesthesiologist, and oncologist should review all radiologic and preoperative data before embarking on the surgery. Older children often can tolerate the surgery under local anesthesia and sedation. Younger children and those whose tumor severely compromises the airway and/or pulmonary artery may require general anesthesia. However, these alternatives should not be used without first a multidisciplinary discussion with the oncologists216 because there is a risk of widespread tumor necrosis that may both render the diagnosis of the cell type difficult and/or induce tumor lysis syndrome.

The restricted spaces in the airway of the child require an understanding and cooperative relationship between surgeon and anesthesiologist order generic maxalt pills, and the use of specially adapted equipment suitable to these cramped areas purchase 10mg maxalt free shipping. Tonsillectomy and Adenoidectomy Untreated adenoidal hyperplasia may lead to nasopharyngeal obstruction purchase genuine maxalt line, causing failure to thrive generic 10 mg maxalt free shipping, speech disorders, obligate mouth breathing, sleep disturbances, orofacial abnormalities with a narrowing of the upper airway, and dental abnormalities. Surgical removal of the adenoids is usually accompanied by tonsillectomy; however, purulent adenoiditis, despite adequate medical therapy, and recurrent otitis media with effusion secondary to adenoidal hyperplasia are improved with adenoidectomy alone. Tonsillectomy is one of the more commonly performed pediatric surgical procedures. In addition, patients with cardiac valvar disease are at risk for endocarditis from recurrent streptococcal bacteremia secondary to infected tonsils. Obstruction of the oropharyngeal airway by hypertrophied tonsils leading to apnea during sleep is an important clinical entity referred to as obstructive sleep apnea syndrome. Despite only mild-to-moderate tonsillar enlargement on physical examination, these patients have upper airway obstruction while awake and apnea during sleep. The goals of treatment are to relieve airway obstruction and increase the cross-sectional area of the pharynx. Some2 patients require the use of nasal continuous positive airway pressure during sleep, whereas others may require a tracheostomy to bypass the chronic upper airway obstruction that is present. The two most frequent levels of obstruction during sleep are at the soft palate and the base of the tongue. Patients may have electrocardiographic evidence of right ventricular hypertrophy and radiographic evidence consistent with cardiomegaly. Each apneic episode causes progressively increased pulmonary artery pressure with significant systemic and pulmonary artery hypertension, leading to ventricular dysfunction and cardiac dysrhythmias. The increased pulmonary vascular resistance and myocardial depression in response to hypoxia, hypercarbia, and acidosis are far greater than what is expected for that degree of physiologic alteration in the normal population. Cardiac enlargement is frequently reversible with surgical removal of the tonsils and adenoids. Preoperative Evaluation A thorough history is the basis for the preoperative evaluation. The presence of audible respirations, mouth breathing, nasal quality of the speech, and chest retractions should be noted. An elongated face, a retrognathic mandible, and a high-arched palate may be present. The oropharynx should be inspected for evaluation of tonsillar size to determine the ease of mask ventilation and tracheal intubation (Fig. The presence of wheezing or rales on auscultation of the chest may be a lower respiratory component of upper airway infection. The presence of inspiratory stridor or prolonged expiration may indicate partial airway obstruction from hypertrophied tonsils or adenoids. Because patients requiring tonsillectomy and adenoidectomy have frequent infections, the parent should be questioned for current use of antibiotics, antihistamines, or other medicines. Many nonprescription cold medications and antihistamines contain aspirin, which may affect platelet function, and this potential anticoagulation should be taken into consideration. In those children with a history of cardiac abnormalities, an echocardiogram may be indicated. It evaluates Snoring, Trouble Breathing, and Un-Refreshed after sleep and has 3396 the potential to be a reliable predictor of children at risk for perioperative respiratory events. Repetitive arousal from sleep to restore airway patency is a common feature, as are episodic sleep-associated oxygen desaturation, hypercarbia, and cardiac dysfunction as a result of airway obstruction. Individuals who experience obstruction during sleep may have snoring loud enough to be heard through closed doors or observed pauses in breathing during sleep. Parents report restless sleep in affected children and frequent somnolence or fatigue while awake despite adequate sleep hours. These children fall asleep easily in nonstimulating environments and are difficult to arouse at usual awakening time. Many of these children have syndromes that are associated 3397 with additional comorbidities. Anatomic nasal obstruction and class 4 touching tonsils reduce oropharyngeal cross-sectional area, which constitutes an additional risk. Pharyngeal size is determined by the soft tissue volume inside the bony enclosure of the mandible; an anatomic imbalance between the upper airway soft tissue volume and craniofacial size will result in obstruction. The magnitude of pharyngeal muscle contraction is controlled by neural mechanisms, and the interaction between the anatomic balance and neural mechanisms determines pharyngeal airway size. Increased neural mechanisms can compensate for the anatomic imbalance in obstructive sleep apnea patients during wakefulness. When these neural mechanisms are suppressed during sleep or anesthesia, pharyngeal dilator muscles do not contract maximally, and therefore the pharyngeal airway severely narrows because of the anatomic imbalance. Increasing the distance between the mentum and the cervical column by positioning will transiently relieve the obstruction so long as the sniffing position is maintained. Similarly, the sitting position displaces excessive soft tissue outside the bony enclosure through the submandibular space. Increased body mass index and obesity may lead to increased cognitive vulnerability, as illustrated by the increased frequency of hyperactivity and increased levels of C-reactive protein. Metabolic syndrome consists of insulin resistance, dyslipidemia, and hypertension. These consist of altered regulation of blood pressure as well as alterations in sympathetic activity and reactivity. Also present are endothelial dysfunction and initiation and propagation of inflammatory response facilitated by increases in levels of C-reactive protein. One of the goals of sedation is maintenance of spontaneous respiration, and, because these patients are at high risk of obstruction, timely emergence is important for safe recovery and discharge. Coincident with these goals, agents with rapid offset such as propofol and dexmedetomidine infusion with or without ketamine bolus are typically used. Once the patient is sedated, nasal endoscopic evaluation is performed to evaluate the upper airway for specific areas of obstruction that would be potentially corrected by surgical intervention. Anesthetic Management The goals of the anesthetic management for tonsillectomy and adenoidectomy are to render the child unconscious, to provide the surgeon with optimal operating conditions, to establish intravenous access to provide a route for volume expansion and medications when necessary, and to provide rapid emergence so that the patient is awake and able to protect the recently instrumented airway. Premedication may be used sparingly; sedative premedication should be avoided in children with obstructive sleep apnea, intermittent obstruction, or very large tonsils. Anesthesia is commonly induced with a volatile anesthetic agent, oxygen, and nitrous oxide (N O) by mask. Tracheal intubation is best accomplished under deep inhalation anesthesia or aided by a short-acting nondepolarizing muscle relaxant. Many 3399 clinicians may choose to eliminate the neuromuscular blocking agent in favor of enhancing the depth of anesthesia with the use of propofol. One study demonstrated that patients undergoing adenotonsillectomy who received fentanyl, 1 to 2 μg/kg, and acetaminophen, 15 mg/kg intravenously or 40 mg/kg rectally, had a median time to postoperative rescue analgesia of 7 and 10 hours, respectively. Codeine should be avoided because of the possibility of rapid metabolism and conversion. For this reason, the supraglottic area may be packed with petroleum gauze, or a cuffed endotracheal tube may be used. If a cuffed endotracheal tube is selected, careful attention to the inflation pressure of the cuff is essential if postextubation croup is to be avoided. Emergence from anesthesia should be rapid, and the child should be alert before transfer to the recovery area. The child should be awake and able to clear blood or secretions from the oropharynx as efficiently as possible before removal of the endotracheal tube. Maintenance of airway and pharyngeal reflexes is essential in the prevention of aspiration, laryngospasm, and airway obstruction. There is no difference in the incidence of airway complications on emergence between patients who are extubated awake and those who are deeply anesthetized. The flexible model has a soft, reinforced shaft that easily fits under the mouth gag without becoming dislodged or compressed. Adequate surgical access can be achieved, and the lower airway is protected from exposure to blood during the procedure. Insertion is possible either after the intravenous administration of 3 mg/kg of propofol or when sufficient depth of anesthesia is achieved using a volatile agent administered by face mask.

This is accomplished by restoring cerebral blood flow, maintaining adequate cerebral perfusion pressure, reducing intracranial pressure, evacuating space occupying lesions, and avoiding fever, hyperglycemia, and hypoxia. Instead, maintenance of euvolemia and a controlled stepwise trial of blood pressure augmentation in patients with suspected vasospasm is recommended. Treatment should not be delayed pending diagnostic evaluation; rather treatment should be started after culture specimens are sent, and antibiotics then “de-escalated” after 48 to 72 hours to ensure adequate initial antibiotic treatment, but avoid long-term overuse of antibiotics. Patients at high risk of death or severely impaired functional recovery should be offered care focused on comfort and not just curative treatment. However, in contrast to other countries, in the United States anesthesiologists have played a smaller role in the specialty, and today comprise a minority of the intensivist workforce. Early on, however, the concept of “intensivists” did not exist, and patients were often managed by their primary physician (be it a surgeon or an internist) and nurses, with formal or informal consultation given by specialists, including anesthesiologists. Safar, the qualities and qualifications of such an individual should include inquisitiveness, thoughtfulness, and a high level of motivation, action orientation, diplomacy, and scientific training. In addition, the aging population is increasing the demand for critical care services. However, the supply of physician intensivists is not expected to keep pace, and instead is projected to decrease through 2025, leading to a worsening shortage of physician providers. Anesthesiologists are hospital-based, have sound fundamental training in physiology, pharmacology, invasive procedures, and monitoring, and have excellent historical and contemporary role models for the anesthesiologist as intensivist. However, evolving reimbursement and staffing models are eliminating these disincentives in many practices. It is clearly beyond the scope of a single chapter to provide detailed coverage of all aspects of critical illness, including physiology, pathophysiology, and management of disease. In addition, many critical care issues are commonly encountered by anesthesiologists who practice solely in the operating room and are covered in detail elsewhere in this text. The entire chapter focuses on evidence-based practices that may improve both patient outcomes and health-care system performance in the perioperative setting. Grading of levels of evidence and practice guidelines in an effort to improve clinical care has become standard practice. Several different grading systems exist, with no clear evidence that one is superior to another. Furthermore, given uncertainty about the methodology of grading systems and their effects on patient outcomes, we have chosen not to include7 “grades” or levels of evidence in this chapter. Processes of care are evidence-based organizational and individual practices that seek to improve the quality of care delivered by standardizing some aspects of health-care delivery. Although the number of potential process targets is nearly limitless, there are only a few that are widely agreed to improve the quality of care. Staffing As advances in medical and surgical therapeutics have increased the complexity of care for an aging and increasingly ill population of patients, it has become increasingly clear that the involvement of intensivists in the management of the critically ill patient is desirable. Patient outcomes appear to be further improved by the addition of multidisciplinary providers to intensivist-led teams. Examples include pharmacist participation in daily rounds, as well as the inclusion of nurses, dieticians, and respiratory therapists. These practices significantly reduce costs and medication-related adverse events, and are also associated with decreased patient mortality. Considering these potential19 benefits and the minimal economic investment required for checklist implementation, their use is strongly recommended. In fact, many of the care processes in this chapter commonly appear on checklists and should be considered with every patient, every day. For example, implementing a standardized order set for patients with septic shock may 4088 lower 28-day mortality. The campaign is designed to reduce unnecessary interventions that lack cost-effectiveness, and has been supported by many medical specialties. Compared with a practice of ordering tests only to answer clinical questions, or when doing so will affect management, the routine ordering of tests increases costs, does not benefit patients and may in fact harm them. Additional recommendations including restrictive23 transfusion thresholds, avoiding oversedation and parenteral nutrition unless clearly indicated, and discussing end-of-life issues are addressed in other sections of this chapter. This type of effort to minimize unnecessary interventions recognizes both the financial impact such practice decisions have on individual patients and the health-care system overall, as well as the physician’s role in providing not just effective, but efficient care. These techniques are discussed in Chapters 26, 37, and 53, and will not be discussed in detail here. In addition, early hyperglycemia (>200 mg/dL) is a reliable independent predictor of poor outcome. The advantages of this scale are that it provides an objective method of measuring consciousness, it has high intra- and inter-rater reliability across observers with a wide variety of experience, and it has an excellent correlation with outcome. After 7 days these figures approximate 80% for both favorable and unfavorable outcome. When both pupils are dilated and unreactive the likelihood of poor neurologic outcome or death is as high as 90% to 95%. When both pupils are reactive, the likelihood of poor neurologic outcome is approximately 30% to 40%, and the probability of good outcome is 50% to 70%. In one report, there was a 15-fold increased risk of mortality in patients with early hypotension and an 11-fold increase in mortality in patients with late hypotension.
