Background and Objective: Manual hyperinflation (MH) technique enhances gas exchange, increase lung compliance, reduce airway resistance, improve lung atelectasis and secretion clearance. However, there is no study about the effects of MH with suction on the circulatory system parameters in paediatric patients with mechanical ventilation. The aims of this study were to compare the effect of MH with suction on the heart rate (HR) and blood pressure (BP) in paediatric patients with mechanical ventilator.
Methods: Twelve pediatric patients with mechanical ventilator admitted at the Pediatric Intensive Care Unit (PICU), Lampang Hospital were studied. Eligible patients randomly received intervention with either (1) MH and suction in morning followed by suction in afternoon, or (2) suction in morning followed by the MH and suction in afternoon, separated by 4 hours for wash-out period. The parameters (HR and BP) were recorded from the patient's bedside monitor display during before and the end of intervention and immediately at 5, 10, 15, 20, 25 and 30 minutes, respectively. Repeated ANOVA with Bonferroni post hoc analysis were used to analysis the parameters. Statistical significance was p<0.05.
Result: The results demonstrated that the HR and BP prior to intervention and at the various time points after the intervention were similar for both interventions (p>0.05). No adverse events during or after MH were noted for any of the patients during this study.
Conclusion: MH with suction had no effect to HR and BP in pediatric patients.
