Lead Sponsor
Aydin Adnan Menderes University
Brief Summary

Aim: The study was carried out to examine the effect of lying positions on hemodynamic parameters in patients with mechanical ventilation (MV) and spontaneous breathing.

Material and Methods: The research was carried out semi-experimentally with a single-group posttest design, between November 2021 and May 2022 in the Internal Medicine Intensive Care (ICU) Unit a University Hospital. The study of the sample consisted of 60 patients in the ICU. Data were collected with the patient identification form and the hemodynamic parameters follow-up form. The patients were given different lying positions for 3 days. Hemodynamic parameters were measured and recorded at the 10th minute, 1st hour and 2nd hour after position changes. The measurement results obtained were compared with one-way ANOVA test.

Detailed Description

Aim: The study was carried out to examine the effect of lying positions on hemodynamic parameters in patients with mechanical ventilation (MV) and spontaneous breathing.

Material and Methods: The research was carried out semi-experimentally with a single-group posttest design, between the dates of 15.11.2021 and 15.05.2022 in the Internal Medicine Intensive Care (ICU) Unit a University Hospital. Since repeated measurements were planned in the study when determining the sample, A-priori power analysis was performed based on ANOVA repeated measures analysis and the effect size was calculated according to the etasquared value (Abd El-Aziz et al., 2021). Accordingly, the sample of the study was calculated as 34 patients to reach at least 80% power within a 95% confidence interval. The research was completed with a total of 60 patients who were spontaneously breathing (n=30) and mechanically ventilated (n=30). Data were collected with the patient identification form and the hemodynamic parameters follow-up form. Right lateral, semi Fowler's, left lateral and supine positions were applied to the patients every 2 hours between 9 am 5 pm for 3 days and then pulse rate, respiratory rate, systolic blood pressure (SBP), diastolic blood pressure (DBP) and oxygen saturation (SpO₂) were measured at 10th minute, 1st hour and 2nd hour. In data analysis, number, arithmetic mean, standard deviation, chi-square, independent groups t test and one-way ANOVA test were used.

Primary Outcome Measures
NameTimeMethod
Respiratory rateMeasurements were made 3 times a day (10th minute, 1st hour and 2nd hour) for 3 days.

The patients' respiratory rate were measured and compared separately in the supine semi-fowler's and lateral positions.

Arterial blood pressureMeasurements were made 3 times a day (10th minute, 1st hour and 2nd hour) for 3 days.

The patients' arterial blood pressure were measured and compared separately in the supine semi-fowler's and lateral positions.

oxygen saturationMeasurements were made 3 times a day (10th minute, 1st hour and 2nd hour) for 3 days.

The patients' oxygen saturation were measured and compared separately in the supine semi-fowler's and lateral positions.

pulse rateMeasurements were made 3 times a day (10th minute, 1st hour and 2nd hour) for 3 days.

The patients' pulse rate were measured and compared separately in the supine semi-fowler's and lateral positions.
