A critical appraisal of a systematic review: Sokol J, Jacob SE, Bohn D: Inhaled nitric oxide for acute hypoxemic respiratory failure in children and adults. Cochrane Database Syst Rev 2003 (1): CD002787.

OBJECTIVE: To review the findings and discuss the implications of the use of inhaled nitric oxide for acute hypoxemic respiratory failure in patients beyond the neonatal period. DESIGN: A critical appraisal of a systematic review. FINDINGS: The authors conducted a systematic review with meta-analysis to determine the effect of inhaled nitric oxide on clinical outcomes of patients with acute hypoxemic respiratory failure. The outcomes included mortality, changes in oxygenation, ventilator-free days, duration of intensive care and hospital stays, and adverse effects. It was a high-quality systematic review provided with strict entry criteria, an extensive literature search, and thorough critical appraisals. Only five trials (n = 623) met entry criteria. Inhaled nitric oxide had no effect on mortality in studies without crossover of treatment failures to open-label inhaled nitric oxide (relative risk, 0.98; 95% confidence interval, 0.66-1.44). A statistically significant improvement in oxygenation was observed in one study. The effect, however, was observed only in the first 4 days of treatment and was not clinically significant. The heterogeneity in study findings precluded meta-analyses of other clinical outcomes and adverse effects in the selected studies. CONCLUSIONS: There is insufficient evidence to determine whether inhaled nitric oxide is beneficial or harmful for acute hypoxemic respiratory failure in children and adults. While awaiting further studies to prove its benefit, inhaled nitric oxide should not either be recommended as a standard management or excluded for the treatment of acute hypoxemic respiratory failure.

[Rapid airway access].

OBJECTIVE: To review the steps involved in safe airway management in critically ill children. SOURCE OF DATA: Review of articles selected through Medline until April 2003 using the following key words: intubation, children, sedation. SUMMARY OF THE FINDINGS: Airway compromise is rare, but whenever it occurs, the situation depends on professionals trained to carry out safe, early, and rapid airway management, with no harm to the patient. The method currently advocated for airway management is rapid sequence intubation, which requires preparation, sedation and neuromuscular block. We observed that it is not possible to apply one single intubation protocol to all cases, since the selection of the most adequate procedure depends on indication and patient conditions. We defined the drug doses most commonly used in our setting, since little is know so far about the real effect of sedatives and analgesics. In most situations, the association of an opioid (fentanyl at 5-10 micro g/kg) with a sedative (midazolam at 0.5 mg/kg) and a neuromuscular blocking agent are sufficient for tracheal intubation. CONCLUSIONS: Training, knowledge, and skill in airway management are of fundamental importance for pediatric intensive caregivers and are vital for the adequate treatment of critically ill children. We present an objective and dynamic text aimed at offering a theoretical basis for the generation of new protocols, to be implemented according to the strengths and difficulties of each service.

[Assessment of intubation procedures at reference pediatric and neonatal intensive care units].

OBJECTIVE: To describe intubation procedures in two pediatric and two neonatal intensive care units in the city of Porto Alegre. METHODS: Cross-sectional study divided into a retrospective and a prospective phase. All intubations performed in these units during a 6-month period were considered. Data were collected by interviewing the physician responsible for the procedure and reviewing the patients' charts, including drugs administered, sedation status, number of attempts, difficulties and complications during the procedure. Data were analyzed using the t test and the Mann-Whitney test for continuous variables and the chi-square test for categorical variables, considering a p < 0.05. RESULTS: Sedatives were administered in 89.5% of the 134 pediatric procedures and 24% of the 116 neonatal procedures (p < 0.001). Muscle relaxants were prescribed for 3% of the children and 0.9% of the neonates. Only 53.7% of the children and 31.9% of the neonates were considered as adequately relaxed. The children who were inadequately relaxed had more intubations attempts (2.4-/+1.3 vs 1.7-/+1.2 p = 0.001), became more hypoxemic (20.9 vs 5.5% p = 0.015) and were more difficult to intubate (54.8 vs 25% p < 0.001). There were more urgent cases and more intubations attempts (2-/+1.2 vs 1.5-/+0.9 p = 0.036) among the inadequately relaxed neonates. Difficulties and complications occurred in 38.8 and 28.3% of the pediatric cases and 29 and 12% of the neonatal cases, respectively. CONCLUSIONS: There was no established routine for intubation procedures in the units studied, and the use of muscle relaxants was not usual. The absence of adequate muscle relaxation is associated with more intubation attempts, difficulties and hypoxemia during the intubation procedure.
