Hemorragia periintraventricular e porencefalia encefaloclástica em prematuros extremos submetidos à fisioterapia respiratória

Abstract

Objective: Realize a literature review about the association between chest physiotherapy and the occurrence of extensive HPIV with consequent impairment of brain parenchyma and developing encephaloclastic porencephaly in preterm infants presenting gestational age (GA) less than 30 weeks and birth weight (BW) less than 1500g. Method: Bibliographic research in the bases Medline, Cochrane, Lilacs, Scielo and Pedro. Key words: chest physiotherapy, premature, brain, haemorrage and their translations into portuguese. The study was restricted in humans, range of time 1990 to 2010, English and Portuguese languages. Results: Have been found 3 studies that investigated the association between chest physiotherapy and encephaloclastic porencephaly, which found as predisposing factors strongly associated with encephaloclastic porencephaly: prematurity or low birthweight. Two studies found an association between chest phisyotherapy, non-cephalic presentation in childbirth and severe hypotention in the first hours of life. However failed to explain the appearance of the lesion or the contribution of each variable. Conclusion: The reviewed studies were inconclusive regarding the association of chest phisyothe rapy with HPIV and encephaloclastic porencephaly. It is necessarie make new studies, that specially investigate its direct association with HPIV, predominant outcomes in neonatal intensive care units. Key Words: Phisycal therapy modalities, premature, brain hemorrhage.
