Laryngo spasm

Respiratory In a meta-analysis of the occurrence of all airway and respiratory adverse events, and the specific occurrence of laryn-gospasm and apnea in 8282 children who received ketamine sedation in an Emergency Department, the incidence of airway and respiratory problems was 319/8282 (3.9%), of which 22 (0.3%) were laryngo-spasm and 63 (0.8%) were apnea [25 ]. Children aged under 2 years and 13 years and over had the highest rates of overall adverse events (OR = 2.72 95% Cl = 1.97, 3.74). Adverse airway and respiratory events were less common with low doses... 

Musculoskeletal Muscle rigidity, laryngo-spasm, and respiratory compromise occurred twice in a 2-day-old full-term neonate, first after a bolus dose of morphine 100 micrograms/kg and then after a continuous infusion of 4.4 micrograms/kg/hour [112 ].
