Suction pressure used for newborns in labour room?

Appeared in: NIMHANS Nursing Officer - 2019

Explanation

The standard suction pressure for a term newborn is 80 to 100 mm Hg.
This range effectively clears secretions from the airway while minimizing the risk of trauma to the delicate neonatal mucosa.
Pressures below this range may be insufficient for adequate clearance, while higher pressures increase the risk of complications like bradycardia and tissue damage.

Option A: This pressure range is too low for a term newborn and may not effectively clear the airway. It is typically used for more fragile, preterm infants.
Option C: This pressure is too high for a newborn and poses a significant risk of causing mucosal trauma, bleeding, and vagal-induced bradycardia.
Option D: This pressure is dangerously high for a newborn and can cause severe injury to the airway mucosa and other complications.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Neonatal Resuscitation and Airway Management as background academic context rather than a clinical decision trigger.
A core nursing responsibility in the delivery room is ensuring all resuscitation equipment is ready and correctly set. Setting the suction pressure appropriately is a critical patient safety measure.
Nurses must monitor the newborn for adverse reactions during suctioning, such as bradycardia, desaturation, or laryngospasm, and be prepared to intervene immediately.
The 'Mouth before Nose' (M before N) suctioning sequence is a vital rule to prevent aspiration. Stimulating the nares can cause a gasp, and if the mouth contains secretions, they can be inhaled into the lungs.

How to Approach the Question

Identify the key terms in the question: 'suction pressure' and 'newborns'.
This is a factual recall question that requires knowledge of standard neonatal care parameters.
Recall the specific, safe pressure range for suctioning a term newborn.
Evaluate the given options against this standard range.
Eliminate options that are too low (for preterm infants) or too high (for children/adults) to identify the correct range.
