Identify the maneuver shown in the diagram, which is used in assisted vaginal breech delivery for the aftercoming head.

Appeared in: NORCERT 8 Mains-2025

Explanation

  • The image clearly depicts the Mauriceau-Smellie-Veit maneuver, a classic technique for delivering the aftercoming head in a breech birth.
  • The operator's forearm supports the fetal body, while the index and middle fingers are placed on the fetal maxilla (cheekbones) to maintain head flexion.
  • Simultaneously, the other hand is placed over the fetal shoulders, applying gentle downward and outward traction to guide the head through the birth canal.
  • This combination of jaw flexion and shoulder traction is the defining characteristic of the Mauriceau-Smellie-Veit maneuver.

Why Other Options Were Wrong

  • Option A: This maneuver is used to deliver the legs in a frank breech presentation, not the aftercoming head.
  • Option B: This technique involves allowing the fetal body to hang passively to use gravity for head flexion, which is contrary to the active manual support shown in the image.
  • Option D: This is used to manage shoulder dystocia in a cephalic (head-first) presentation, not for a breech delivery.

Visual explanation — Related Visual
  • Visual 1: Diagram Series - A set of four diagrams, one for each maneuver (Mauriceau-Smellie-Veit, Pinard, Burn-Marshall, McRoberts), to visually contrast their specific applications and techniques.
  • Visual 2: Animation - A short animation demonstrating the step-by-step process of the Mauriceau-Smellie-Veit maneuver, emphasizing the correct hand placements and direction of traction.
Clinical Relevance
  • Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Obstetric maneuvers for assisted breech delivery as background academic context rather than a clinical decision trigger.
  • Proper execution of maneuvers for the aftercoming head is critical to prevent head entrapment, a major cause of neonatal morbidity (e.g., brachial plexus injury, hypoxia) and mortality in breech births.
  • Nurses must anticipate the need for such maneuvers in a planned breech delivery, ensure specialized equipment like Piper forceps is readily available, and be prepared to assist the provider.
  • A key nursing assistance role may include applying suprapubic pressure (not fundal pressure) as directed by the obstetrician to help keep the fetal head flexed during delivery.
How to Approach the Question
  • First, analyze the image to identify the key actions being performed by the healthcare provider and the position of the fetus. Note the hands on the baby's face and shoulders.
  • Read the stem carefully to understand the clinical context. Key phrases are 'assisted vaginal breech delivery' and 'aftercoming head'.
  • Evaluate each option by recalling the definition and primary purpose of the specific obstetric maneuver.
  • Compare the actions in the image (hand on maxilla, hand on shoulders, supporting forearm) with the definition of each maneuver.
  • Eliminate options used for different purposes (like Pinard for legs) or different presentations (like McRoberts for cephalic shoulder dystocia).
  • Select the option that perfectly matches the visual evidence and the clinical scenario described in the question.
Concept Tested & Keywords
  • Concept Tested: Obstetric maneuvers for assisted breech delivery
  • Stem keywords: assisted vaginal breech delivery, aftercoming head, maneuver, diagram
  • Lead-in keywords: Identify
  • Clinical cues: The image shows a breech presentation, which requires specific delivery techniques.
  • Clinical cues: The focus on the 'aftercoming head' is a key clue to the stage of delivery and the purpose of the maneuver.
