Perioperative management issues in pediatric patients

Pediatric Ambulatory Anesthesia Challenges

Ambulatory surgery in the pediatric population can be similar to adult ambulatory with a few different challenges. Success is best determined by appropriate preoperative screening. Issues common in pediatrics are the respiratory infection, asthma, congenital heart disease and syndromes, as well as sleep apnea. Risk factors for adverse respiratory events and patient transfer differ from adults as do data for rapid discharge.

Pediatric Review and Perioperative Considerations

Perioperative management of pediatric patients demands knowledge of the relevant ways in which pediatric physiology and physiological regulation differs from the adult. This article will outline some of these most pertinent differences, and also present current recommendations for perioperative management.

Pediatric sedation and anesthesia for the oral surgeon

Even simple oral and maxillofacial surgical procedures can become challenging when the child patient has a high degree of fear and anxiety. This article reviews differences in anatomy and physiology between the adult and pediatric patient, preanesthetic assessment, fasting guidelines, and choices of sedation routes, and discusses equipment options for the management of pediatric anesthesia. After reflection on these topics and based on training and experience, oral and maxillofacial surgeons can decide the ages of patients, medical comorbidities, and techniques with which they are comfortable in performing surgery in their offices in a safe and effective manner.

The perioperative management of pain from intracranial surgery

Analgesic therapy following intracranial procedures remains a source of concern and controversy. Although opioids are the mainstay of the "balanced" general anesthetic techniques frequently used during intracranial procedures, neurosurgeons and others have been reluctant to administer opioid analgesics to patients following such procedures. This practice is supported by the concern that the sedation and miosis associated with opioid administration could mask the early signs of intracranial catastrophe, or even exacerbate it through decreased ventilatory drive, elevated arterial carbon dioxide levels, and increased cerebral blood flow. This reluctance to use opioids following intracranial surgery is enabled by decades of training and anecdote emphasizing that pain is minimal following these procedures. However, recent data suggests otherwise, and raises the question of how to provide safe and effective analgesia for these patients. Here, this data is reviewed along with the relevant pain pathways, analgesic drugs and techniques, and the available data on their use following intracranial surgery. Although pain following intracranial surgery appears to be more intense than initially believed, it is readily treated safely and effectively with techniques that have proven useful following other types of surgery, including patient-controlled administration of opioids. The use of multimodal analgesic therapy is emphasized not only for its effectiveness, but to reduce dosages and, therefore, side effects, primarily of the opioids, that could be of legitimate concern to physicians and affect the comfort of their patients.

Evaluation of satisfaction level by parents and children following pediatric anesthesia

BACKGROUND

Research in the field of patient satisfaction first took place in the 1980s in the USA, and later in Europe, aimed at meeting competitive requirements in the field of health care. Very few studies of this type exist in regard to pediatric anesthesia. Our aim was to develop a rapidly interpretable questionnaire to measure the level of parental satisfaction when their children undergo surgery and provide information on those factors triggering anxiety in these children.

METHODS

Over a period of 18 months 179 parents of children in pediatric surgery responded to 214 questionnaires designed to investigate principally the emotional/behavioral spheres as well as the comfort provided.

RESULTS AND CONCLUSIONS

We found that parents generally expressed a high degree of satisfaction which was good and correlated significantly with environmental comfort and postoperative observations performed by anesthetists and nursing staff. In the children, lack of fear at the moment of being anesthetized, and lack of anxiety on the day preceding surgery, were attributed to the serenity transmitted by the anesthetist and nurses. Significant anxiety resulted from the fear of an unpleasant impact with the operating room.

Prevention and treatment of postoperative pain with particular reference to children

Pain therapy is an important aspect of medical practice for patients of all ages, to optimize care, to obtain an adequate quality of life and to improve their general conditions. Pain is among the most prevalent symptoms experienced by patients undergoing surgery. The success of postoperative pain therapy depends on the ability of the clinician to assess the presenting problems, identify and evaluate pain syndromes and formulate a plan for comprehensive continuing care. The prevalence of acute pain has led to the need to develop techniques for the assessment and management of this symptom in order to focus the attention on an interdisciplinary therapeutic approach (including pharmacologic, cognitive-behavioral, psychologic and physical treatment) and on the timing of different interventions (pre and postoperative). In this chapter we describe the principal therapeutic approaches to control pain in post-operative patients, such as non-opioid, opioid and adjuvant analgesics with particular attention in paediatric age. Moreover we report the principal scales to assess the pain intensity in the post-operative period. The need of a multidisciplinatory team and of a pre and postoperative pain management program represents an important goal in order to obtain effective pain relief and optimize pediatric care and rapid recovery. The introduction of a perioperative team service will improve the approach to pain management programs and it is considered the most important challenge for future.

Urological Manifestations of Down Syndrome

PURPOSE

We identified the urological anomalies seen in patients with Down syndrome.

MATERIALS AND METHODS

We reviewed the literature on Down syndrome and its associated genitourinary pathology.

RESULTS

Associated defects have been reported throughout the genitourinary tract. The most common renal anomalies seen are renal hypoplasia, obstructive uropathy and glomerular microcysts. Decreased creatinine clearance has also been noted. Developmental anomalies, such as megaureter and vesicoureteral reflux, have been reported. Dysfunctional voiding and urinary retention have been found in these patients. Posterior urethral valves and hypospadias have also been seen. The testicular abnormalities most frequently reported are cryptorchidism, testicular cancer and infertility.

CONCLUSIONS

Improved understanding and identification of the various urological anomalies associated with Down syndrome will aid in the care of these patients. In addition, an awareness of perioperative issues will further facilitate a smooth clinical course.

Extubation of pediatric patients by PACU nurses

Traditionally, the role of the PACU nurse has been to evaluate patient readiness for extubation, with the responsibility of tracheal extubation performed by the anesthesiologist or Certified Registered Nurse Anesthetist (CRNA). In our PACU, registered nurses routinely evaluate and extubate the majority of surgical cases. Our experience has shown that extubation by the PACU nursing staff improves airway management skills without compromising patient safety and facilitates OR turnover time. In this article, tracheal extubation performed by PACU nurses is detailed and a case study is presented.

Risk factors prolonging ventilation in young children after cardiac surgery: Impact of noninfectious pulmonary complications

OBJECTIVE: To determine risk factors for prolonged ventilation after cardiac surgery in young children and assess the impact of noninfectious pulmonary complications on ventilatory duration. DESIGN: Retrospective case series analysis. SETTING: A tertiary pediatric cardiac center. PATIENTS: Clinical records of 222 consecutive children aged </=3 yrs undergoing cardiac surgery for congenital heart disease were reviewed. Fifteen patients, consisting of six premature babies and nine who died within 72 hrs of surgery, were excluded. MEASUREMENTS AND MAIN RESULTS: The demographic data, preoperative risk factors, surgical procedures performed, intraoperative variables, and postoperative complications of the remaining 207 children were reviewed. Univariate analysis was performed to compare patients who required prolonged ventilation (>72 hrs) to those who could be extubated at </=72 hrs, and multivariate analyses were performed to identify significant determinants on ventilatory duration and impact of noninfectious complications. Of the 182 patients undergoing open heart surgery, 45 (25%) required prolonged ventilation for a median of 8 days. The latter were significantly younger in age and lighter in weight and were more likely to have Down syndrome, preoperative pulmonary hypertension and ventilatory support, undergone more complex surgery requiring longer bypass and circulatory arrest time, postoperative cardiovascular and pulmonary complications, and extubation failure (all p values <.01). Of the 25 patients who had closed heart surgery, five (20%) required prolonged ventilation for a median of 14 days. The latter were more likely to require preoperative ventilation, have undergone more complex surgery, had postoperative cardiovascular and pulmonary complications, and had extubation failure (all p values <.05). Cox proportional hazard regression identified body weight (p <.001), Down syndrome (p =.02), need for preoperative ventilation (p <.001), complexity of surgery (p <.001), cardiovascular complications (p <.001), and infective (p <.001) and noninfective (p <.001) pulmonary complications to be significant factors that determined the ventilatory duration. Noninfectious pulmonary complications occurred in 31.9% (58/182) and 20% (5/25) of patients after open and closed heart surgery, respectively. In the absence of other risk factors, the median time to extubation was similar between patients with and without noninfectious complications (1 vs. 0.8 day). However, in the presence of other risk factors, noninfectious pulmonary complications prolonged the median time to extubation from 8 to 18 days. Logistic regression identified Down syndrome (p =.005), preoperative ventilation (p =.001), complexity of surgery (p =.006), and bypass time (p =.005) as risk factors for development of noninfectious pulmonary complications. CONCLUSIONS: Noninfectious pulmonary complications that occurred commonly after cardiac surgery in young children prolong ventilatory duration only in the presence of other risk factors, with which it acts in a synergistic fashion.
