Abstract

Objective: To determine the effect of electrolyte disturbances (ED) and asphyxia on infant hearing and hearing outcomes. Study design: We conducted newborn hearing screening with transient evoked otoacoustic emission (TEOAE) test on a large scale (>5000 infants). The effects of ED and asphyxia on infant hearing and hearing outcomes were evaluated. Result: The pass rate of TEOAE test was significantly reduced in preterm infants with ED (83.1%, multiple logistic regression analysis: P<. 0.01) but not in full-term infants with ED (93.6%, P=. 0.41). However, there was no significant reduction in the pass rate in infants with asphyxia (. P=. 0.85). We further found that hypocalcaemia significantly reduced the pass rate of TEOAE test (86.8%, P<. 0.01). In the follow-up recheck at 3 months of age, the pass rate remained low (44.4%, P<. 0.01). Conclusion: ED is a high-risk factor for preterm infant hearing. Hypocalcaemia can produce more significant impairment with a low recovery rate.
