Rescue high-frequency jet ventilation versus conventional ventilation for severe pulmonary dysfunction in preterm...

Area of Science:

• Neonatal Medicine
• Respiratory Physiology
• Critical Care

Background:

• Chronic lung disease (CLD) is a significant cause of mortality in very low birth weight infants.
• Mechanical ventilation, while life-saving, can contribute to lung injury.
• High-frequency jet ventilation (HFJV) is explored as a method to mitigate ventilator-induced lung injury.

Purpose of the Study:

• To compare the efficacy of HFJV versus conventional ventilation (CV) in preterm infants with severe pulmonary dysfunction.
• To conduct subgroup analyses based on surfactant therapy, lung volume maintenance, gestational age, birth weight, and humidification.

Main Methods:

• Systematic review including randomized and quasi-randomized controlled trials.
• Included preterm infants (<35 weeks gestation or <2000g) in respiratory distress.
• Data analyzed using risk ratios (RRs) and risk differences (RDs).

Main Results:

• Only one trial (144 infants) was included in the review.
• No statistically significant difference in overall mortality between HFJV and CV.
• No significant differences in CLD, intraventricular hemorrhage, air leaks, airway obstruction, or necrotizing tracheobronchitis.

Conclusions:

• Current evidence does not support HFJV as a rescue therapy for preterm infants due to imprecise results and limitations in trial design.
• The single included study had insufficient power to assess important adverse effects.
• Further high-quality trials with adequate power, focusing on high-risk populations and long-term outcomes, are necessary.
