PMID 39073065WHAT IT FOUND
In 51 preterm infants, suctioning longer than 13 seconds was linked to lower brain oxygen, slower recovery, higher pain, and lower blood oxygen.
Nurses should monitor oxygen and pain.
Key findings
01Longer suctioning duration was associated with lower cerebral oxygenation during suctioning.
02A 13-second suctioning duration was identified as a threshold for cerebral oxygenation falling below 60%, with 89% sensitivity and 61% specificity.
03Infants suctioned longer than 13 seconds had higher pain scores, larger drops in cerebral oxygenation, longer recovery times, and lower SpO2 before and during suctioning than infants suctioned for 13 seconds or less.

What it does not show
Single centre, third-level NICU, so practice and patient mix may not generalise. Only cerebral oxygenation was monitored, not oxygenation of other tissues. Infants had different diagnoses, which could affect cerebral oxygenation. The study observed suctioning duration rather than assigning it, so it cannot show that longer suctioning caused the changes. The 13-second threshold was derived from the data and then used to create comparison groups. All suctioning was performed by one experienced nurse, which may limit applicability to other clinicians.
Declared interests
No specific grant funding was received, and the authors declared no conflicts of interest.
The easy way to misread this
Do not treat 13 seconds as a proven safe maximum. The study observed natural suctioning durations and found associations with lower cerebral oxygenation, pain, and slower recovery; it did not test different suctioning durations, and the threshold was chosen after looking at the data.
