Rarely, negative pressure pulmonary edema may occur and requires specific treatment.37The high chest wall to lung compliance ratio observed during infancy, which disappears by the second year of life because of increased chest wall stiffness, may explain why negative pressure pulmonary edema is less frequent in infants than in older children or adults. Experimental evidences and anecdotal reports indicate that intraosseous and IV injection behave similarly, resulting in adequate intubating conditions within 45 s (1 mg/kg).57In children in whom succinylcholine is contraindicated, rocuronium administered at a dose of two to three times the ED95(0.9 to 1.2 mg/kg) may represent a reasonable substitute when rapid onset is needed.58,,60In addition, there is a possibility to quickly reverse the neuromuscular blockade induced by rocuronium using sugammadex if necessary.61.
