To analyze the role of passive leg raising on
cerebral oxygenation assessed with near-infrared
spectroscopy (NIRS) in sepsis patients in the ICU RSUP
H. Adam Malik using data from the mean value of
cerebral oxygenation in sepsis patients and assessing the
cerebral oxygenation difference before and after passive
leg raising (PLR).
Methods: It is a cross-sectional study conducted at H.
Adam Malik Hospital, Medan from June 2021 until the
sample is sufficient. Research subjects were taken by
consecutive sampling technique, a total of 27 samples.
Samples that met the inclusion criteria were monitored
and recorded their hemodynamics (blood pressure, heart
rate, mean arterial pressure) and rSO2using NIRS
before PLR (T0) was performed. Furthermore, PLR was
performed by raising the patient's legs 45° for 1 minute,
and then monitoring and re-recording hemodynamics
and rSO2was done (T1). Monitoring and re-recording
were carried out 5 minutes after the PLR (T2) was
performed with the NIRS pad still attached to the
patient.
Results: The results showed that there was a statistically
significant difference between the right rSO2and the left
rSO2before PLR and after 1-minute post-intervention
with a p-value <0.05. The same results were also
obtained in the comparison of right rSO2with left
rSO2before PLR and after 5 minutes post-intervention
where the p-value <0.05 showed a significant difference.
Comparison between right rSO2and left rSO2at oneminute post-intervention and after five minutes, p-value
> 0.05 showed that there was no statistically significant
difference.
Conclusion: There was a significant change in cerebral
oxygenation after passive leg raising action, while at 5
minutes there was no significant change in cerebral
oxygenation
