Pediatric airway issues

Guidelines for Monitoring and Management of Pediatric Patients Before, During, and After Sedation for Diagnostic and Therapeutic Procedures

The safe sedation of children for procedures requires a systematic approach that includes the following: no administration of sedating medication without the safety net of medical/dental supervision, careful presedation evaluation for underlying medical or surgical conditions that would place the child at increased risk from sedating medications, appropriate fasting for elective procedures and a balance between the depth of sedation and risk for those who are unable to fast because of the urgent nature of the procedure, a focused airway examination for large (kissing) tonsils or anatomic airway abnormalities that might increase the potential for airway obstruction, a clear understanding of the medication's pharmacokinetic and pharmacodynamic effects and drug interactions, appropriate training and skills in airway management to allow rescue of the patient, age- and size-appropriate equipment for airway management and venous access, appropriate medications and reversal agents, sufficient numbers of appropriately trained staff to both carry out the procedure and monitor the patient, appropriate physiologic monitoring during and after the procedure, a properly equipped and staffed recovery area, recovery to the presedation level of consciousness before discharge from medical/dental supervision, and appropriate discharge instructions.

Comparison of the GlideScope Cobalt® and Storz DCI® Video Laryngoscopes in Children Younger Than 2 Years of Age During Manual In-Line Stabilization: A Randomized Trainee Evaluation Study

OBJECTIVES

Video laryngoscopy facilitates tracheal intubation during manual in-line stabilization in adults, but it is not clear whether these findings translate to children. We compared trainee intubation times obtained using the GlideScope Cobalt® and Storz DCI® video laryngoscopes versus direct laryngoscopy in young children with immobilized cervical spines.

METHODS

Ninety-three children younger than 2 years underwent laryngoscopy with manual in-line stabilization using direct laryngoscopy, GlideScope Cobalt® video laryngoscopy, or Storz DCI® video laryngoscopy. Laryngoscopists were anesthesiology trainees in postgraduate training year of 3 or more. Total time to successful intubation (TTSI), best glottic view, and maximum degrees of neck deviation were recorded. An intubation time difference longer than 10 seconds was defined as clinically significant.

RESULTS

Data are reported as median; 95% confidence interval. The TTSI was similar among groups although Storz times were longer (median, 33.3 seconds; 95% confidence interval, 26.2-43.3 seconds) when compared to direct laryngoscopy (median, 23.3 seconds; 95% confidence interval, 20.7-26.5 seconds; P = 0.02). Obtaining a grade 1 Cormack-Lehane glottic view was less likely with direct laryngoscopy (P = 0.002). Maximum degrees of neck deviation were: Storz (median, 2.0; 95% confidence interval, 1.2-2.8), GlideScope (median, 2.0; 95% confidence interval, 1.4-2.6), and direct laryngoscopy (median, 1.9; 95% confidence interval, 1.2-2.1; P = 0.48).

CONCLUSIONS

Trainees were able to safely perform tracheal intubation in children younger than 2 years using any of the studied laryngoscopes, although Storz use resulted in a longer TTSI when compared to direct laryngoscopy. Video laryngoscopy may enhance best Cormack-Lehane glottic view during manual in-line cervical spine immobilization, but additional technical skills are needed to successfully complete tracheal intubation.

Perioperative management of pediatric trauma patients

Pediatric trauma presents significant challenges to the anesthesia provider.

This review describes the current trends in perioperative anesthetic management, including airway management, choice of anesthesia agents, and fluid administration.

The review is based on the PubMed search of literature on perioperative care of severely injured children.

Pediatric trauma anesthesia

Trauma has a significant impact on pediatric morbidity and mortality. Depending on the emergency medical services and health care system, anesthesiologists may be involved in pediatric trauma care at the scene, in the emergency department, in the operating room, or in the intensive care unit. Familiarity with the pathophysiology of pediatric trauma and age-dependent anatomical and physiological features is, therefore, essential to every anesthesiologist. Fast and appropriate interventions with respect to the clinical status and the suspected injuries are the key to successful treatment. Due to the high incidence of head injury, airway management and hemodynamic stabilization are of utmost importance. For preclinical trauma care, however, evidence-based data showing a gold standard for pediatric trauma care are still lacking.

Canadian pediatric anesthesiologists prefer inhalational anesthesia to manage difficult airways: A survey

PURPOSE

To survey Canadian pediatric anesthesiologists to assess practice patterns in managing pediatric patients with difficult airways.

METHODS

Canadian pediatric anesthesiologists were invited to complete a web survey. Respondents selected their preferred anesthetic and airway management techniques in six clinical scenarios. The clinical scenarios involved airway management for cases where the difficulty was in visualizing the airway, sharing the airway and accessing a compromised airway.

RESULTS

General inhalational anesthesia with spontaneous respiration was the preferred technique for managing difficult intubation especially in infants (90%) and younger children (97%), however, iv anesthesia was chosen for the management of the shared airway in the older child (51%) where there was little concern regarding difficulty of intubation. Most respondents would initially attempt direct laryngoscopy for the two scenarios of anticipated difficult airway (73% and 98%). The laryngeal mask airway is commonly used to guide fibreoptic endoscopy. The potential for complete airway obstruction would encourage respondents to employ a rigid bronchoscope as an alternate technique (17% and 44%).

CONCLUSION

Inhalational anesthesia remains the preferred technique for management of the difficult pediatric airway amongst Canadian pediatric anesthesiologists. Intravenous techniques are relatively more commonly chosen in cases where there is a shared airway but little concern regarding difficulty of intubation. In cases of anticipated difficult intubation, direct laryngoscopy remains the technique of choice and fibreoptic laryngoscopy makes a good alternate technique. The use of the laryngeal mask airway was preferred to facilitate fibreoptic intubation.

Airway management in the obese child

Airway management in severely obese children requires familiarity with the equipment and techniques used for establishing a patent airway. Normal anatomic landmarks are obscured in these patients, making assessment a challenge. Therapy should be individualized, and because the airway is marginal in many of these patients, small insults, such as respiratory tract infection or loss of muscle tone during sleep, can result in a perilous airway. Pediatric airway charts should be maintained and reviewed frequently in emergency departments and clinics caring for these patients. Currently, the body of literature devoted to airway management in obese children is small. Inconsistencies in parameters make comparison of studies difficult. Continued, consistent reporting of airway-management issues in these patients is needed.
