INTRODUCTION: Infant crying is a major expression of distress and can occur without any exogenous stimulation. Little is known, however, about the effects of crying on physiological homeostasis in very preterm infants (VPIs). METHODS: Environmental, behavioral (video and audio recording) and physiologic (heart rate [HR], respiratory rate [RR], and systemic [SaO(2)] and regional cerebral oxygenation [rSO(2)]) parameters were prospectively evaluated over 10h in 18 VPIs (median gestational age, 28 [27-31] weeks). Only episodes of "spontaneous" and isolated cries were analyzed. Changes in parameters were compared over 5-second periods between baselines and 40s following the onset of crying. Two periods were distinguished: 0-20s (a) and 20-40s (b). Minimal and/or maximal values in these periods were also compared to the baseline. RESULTS: Of the 18 VPIs initially studied, 13 (72%) presented crying episodes (CE). They experienced 210 "spontaneous" and isolated CE, with a median of 9 [range, 1-63] CEs per child. Physiological values varied significantly from the baseline with mainly a mean decrease in HR of -4.8±5.3beats/min (b) after an initial mean increase of +2.6±2.0beats/min (a); a mean decrease in RR of -3.8±4.8cycles/min (a), followed by a mean increase of +5.6±7.3cycles/min (b) and mean unidirectional decreases in SaO(2) and rSO(2) (minimal values) of -1.8±2.3% and -2.5±3.0%, respectively. CONCLUSION: Spontaneous cries can alter the homeostasis of VPIs. Their possible adverse consequences and high occurrence emphasize the need for better prevention and response to them.
