Brief Summary

The aim of this study was to examine the effect of positioning on respiratory functions of preterm infants after extubation.

Hypothesis 0a (H0a): There is no difference between the oxygen saturation (SpO2) levels of preterm infants in supine and prone positions after extubation.

Hypothesis 0b (H0b): There is no difference between the respiratory rate of preterm infants in supine and prone positions after extubation.

Hypothesis 0c (H0c): There is no difference between the respiratory rhythms of preterm infants in supine and prone positions after extubation.

Hypothesis 0d (H0d): There is no difference between respiratory distress in preterm infants in supine and prone positions after extubation.

Detailed Description

Among infants in the neonatal intensive care unit (NICU), the ones in the high and medium risk group are premature infants. Respiratory distress is the most important problem in infants with a history of preterm birth due to undeveloped systems and organs. Especially premature infants need respiratory support in the NICU. The most important stage of supportive treatment is the application of mechanical ventilation with endotracheal intubation. Newborns receiving mechanical ventilation support should be checked constantly Considering that endotracheal intubation may cause extreme stress and traumatic effects on premature babies, it should be ensured that premature babies get through the ventilation process and afterward with minimal trauma. This will positively affect the adaptation process after the termination of intubation. The neonatal nurse continuously monitors the changes in heart rate, body temperature, blood pressure, SpO2, respiratory characteristics and number of infants receiving mechanical ventilation and records them in the patient follow-up form. The nurse tries to provide the most ideal respiratory form in infants with mechanical ventilation. For this reason, neonatal nurses should provide individualized developmental nursing care by considering all the physiological needs of premature babies in order to provide the most ideal respiratory form. The use of individualized care models in premature babies increases the health quality and social cohesion of preterm babies. It fastens the physiological recovery, shortens the hospital stay and increases neurodevelopmental functions. Positionig is one of the most important developmental supportive activities. It is important in nursing care to position the preterm babies appropriately and to ensure its continuity according to their needs. It is recommended that preterm infants with respiratory distress in the NICU should be placed in the supine position after extubation when respiratory patterns are stabilized. It has been observed that the prone position increases oxygen saturation in premature babies, shortens the duration of mechanical ventilator therapy, decreases re-intubation after extubation, decreases neonatal apnea, and contributes to the development of respiratory muscles and positively affects respiratory functions. In addition, the prone position increases the lung capacity of preterm infants. Studies show that the prone position improves diaphragmatic function, increases lung perfusion, and has positive effects on respiratory functions. In another study, it was stated that the prone position is a safe and healthy process according to the order of separation from mechanical ventilation and may contribute to the success of separation from mechanical ventilation in preterm infants [4]. The neonatal nurse should be aware of the importance of positioning and should be able to position the newborn baby when needed in routine care practices. During the respiratory system intubation period and after extubation, the effects of the positioning on the respiratory functions of the preterm should be observed and the position with the highest benefit should be taken into consideration when performing individualized nursing care. Therefore, the aim of this study was to examine the effect of positioning on respiratory functions of preterm infants after extubation.

Study Groups

Supine position group

Supine position group Before starting the study, parents of preterm infants were informed about the study, and the infants of parents who agreed to participate in the study were divided into two groups as prone and supine positions. In the study, preterm babies positioned after extubation by the researcher. Before extubation, SpO2, respiratory rate (to be counted for one minute), blood pressure, blood gas values were checked and recorded from the bedside monitor of the babies planned for extubation. Before leaving the mechanical ventilator for preterm newborns who were decided for extubation and met the research criteria, vibration and percussion were performed to premature babies over 1500 g with a mouth mask or palm dome. Oral, nasal and oranazopharynx were aspirated for 3-5 seconds with an appropriate aspiration catheter (6-8 Fr) at a pressure not exceeding 100 mmHg.

Group Type: EXPERIMENTAL

The effect of positioning on respiratory functions of preterm infants after extubation.

Intervention Type: OTHER

Position changes and the direction of the position (supine, prone, side lying) are recorded in the nurse observation form.

Prone position group

Prone position group Before starting the study, parents of preterm infants were informed about the study, and the infants of parents who agreed to participate in the study were divided into two groups as prone and supine positions. In the study, preterm babies positioned after extubation by the researcher. Before extubation, SpO2, respiratory rate (to be counted for one minute), blood pressure, blood gas values obtained from the heel blood of the Preterm baby were checked on the bedside monitor and recorded before extubation. Before leaving the mechanical ventilator for preterm newborns who were decided for extubation and met the research criteria, vibration and percussion were performed to premature babies over 1500 g with a mouth mask or palm dome. Oral, nasal and oranazopharynx were aspirated for 3-5 seconds with an appropriate aspiration catheter (6-8 Fr) at a pressure not exceeding 100 mmHg.
