Identify, which of the following retractor is used in abdominal surgery?

Doyens Retractor Surgical Instrument ...

Appeared in: AIIMS Delhi NO- 2019

Explanation

  • The instrument shown is a Doyen retractor, identified by its wide, curved, saddle-shaped blade and fenestrated handle.
  • It is a handheld abdominal retractor used in various abdominal and pelvic surgeries.
  • Its most classic application is in Cesarean sections, where it is used to retract the urinary bladder inferiorly to protect it from injury during uterine incision.
  • The shape of the blade is specifically designed to cup and hold the bladder safely out of the surgical field.

Why Other Options Were Wrong

  • Option A: Vaginal surgeries use different types of retractors, such as speculums (e.g., Auvard's weighted speculum, Sims' speculum), which are designed to open the vaginal canal. A Doyen retractor is too large and shaped for abdominal, not vaginal, retraction.
  • Option B: A thoracotomy involves opening the chest cavity. This requires robust instruments capable of spreading the ribs, such as a Finochietto rib spreader. A Doyen retractor lacks the strength and design for this function.
  • Option D: This option is incorrect because 'Cesarean section' is a valid and primary use for the Doyen retractor.

Clinical Relevance
  • Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Identification and application of surgical instruments as background academic context rather than a clinical decision trigger.
  • A crucial nursing responsibility in the operating room is to anticipate the surgeon's needs and ensure the correct instruments are ready. For a Cesarean section, the scrub nurse must have the Doyen retractor available immediately after the abdominal cavity is opened to facilitate bladder protection.
  • Proper instrument identification is a key competency for patient safety. Handing the wrong instrument can cause delays, increase surgical time, and potentially lead to tissue damage.
  • What if the Doyen retractor is unavailable? The surgeon might use a malleable or a Deaver retractor as a substitute, but these may not provide the same optimal, gentle, and stable retraction of the bladder, slightly increasing the risk of injury.
How to Approach the Question
  • First, carefully examine the image to identify the key features of the surgical instrument. Note the wide, curved, saddle-like blade and the long handle with a hole.
  • Based on these features, identify the instrument. This is a Doyen retractor.
  • Next, recall or deduce the function of the instrument based on its design. The wide, curved blade is designed to hold back a large, soft organ without causing damage.
  • Evaluate the given options, which are types of surgeries. Consider in which of these procedures such retraction would be necessary.
  • A Cesarean section is an abdominal surgery involving an incision near the bladder. Retracting the bladder is a critical step, making the Doyen retractor a perfect fit.
  • Eliminate the other options. Thoracotomy requires rib spreading, and vaginal surgery uses different types of speculums. Therefore, Cesarean section is the most appropriate answer.
