Hammock Positioning's Influence on the Electromyographic Activity in the Flexor Muscles in Newborn Preterm

Summary

The individual who is born premature, in addition to a CNS still in accelerated training suffers early loss of intrauterine restraint, conditions that promote hypotonia characteristic of premature birth. Given this hypotonia associated with musculoskeletal immaturity when improperly positioned in the incubator for an extended period, the PN can develop joint contractures and postural imbalances that, in most cases, are transitory, however can become persistent, causing delay in their Motor development. The aim of this study is to analyze the influence of the positioning of preterm infants in the incubator hammock on the tone and the myoelectric activity of the rectus abdominis flexor muscles, biceps and hamstrings. Study type controlled, randomized, double-blind, to be carried out from November 2015 to April 2016 will be obtained two groups, control (in containment nest "U") and experimental (with hammock) to from randomized samples with premature births in Barao de Lucena Hospital or the Hospital das Clinicas, UFPE, the Intermediate Care Units (ICU) Neonatal. The sample will consist of 30 premature. To collect, pulse oximeter will be used, electromyography, neurological testing Dubowitz and recording behavioral responses. Each baby will be accompanied for about 8 hours daytime placement for two days and three evaluations performed.

Conditions

• Preterm Birth

Interventions

DEVICE

hammock

PN who will be positioned in hammock inside the incubator will be with the high trunk to about the 30th, and will be used a roll of restraint in the neck by keeping a slight lordosis to avoid suffocation risks. In two days of placement, should remain about 8 hours in the hammock, being removed during cleaning procedures, diet and medical evaluation and then immediately replaced in the hammock. The alternation of decubitus (right side, supine and left lateral) should be performed whenever the child is manipulated for these procedures.

DEVICE

containment nest

In the control group, the position will follow the routine procedure of the Hospital Barão de Lucena, consisting of the use of restraint nests "U", made with rolled sheet placed on the mattress of the incubator and covered by another sheet. The control group incubators will also be inclined at 30 ° as routine service. During the 8 position, switching the supine will also be held, side left and side right after the baby handling to cleaning procedures, diet and medical evaluation.
