SafeLM Versus LMA Classic for Airway Management During Fibroadenoma Excision

2. Oktober 2026 aktualisiert von: Hanoi Medical University

Comparison of Airway Control Effectiveness of the SafeLM Video Laryngeal Mask and the LMA Classic in Patients Undergoing General Anesthesia for Fibroadenoma Excision

This randomized controlled trial compares the airway management performance of the SafeLM video laryngeal mask with the LMA Classic in adult patients undergoing elective fibroadenoma excision under general anesthesia. Participants will be randomly assigned to airway management with either the SafeLM or the LMA Classic. The primary outcome is oropharyngeal leak pressure. Secondary outcomes include insertion performance, ventilation parameters, hemodynamic responses, and airway-related adverse events.

Detaillierte Beschreibung

The SafeLM is a video-assisted laryngeal mask that allows visualization during placement, whereas the LMA Classic is a conventional supraglottic airway device. This study is designed to compare the clinical performance of these two devices under standardized conditions.

Adult patients scheduled for elective fibroadenoma excision under general anesthesia will be screened for eligibility. Only patients for whom both devices are considered clinically appropriate will be enrolled, thereby avoiding randomization when patient characteristics indicate a preference for a particular airway management technique. Eligible participants will be randomly assigned to airway management with either the SafeLM or the LMA Classic.

After standardized induction of general anesthesia, the assigned laryngeal mask will be inserted according to the study protocol. The primary outcome is oropharyngeal leak pressure after successful placement. Device insertion characteristics, ventilation parameters, hemodynamic responses, and airway-related adverse events will also be evaluated.

Beschreibung

Inclusion Criteria:

  • Female patients aged 18 years or older.
  • Scheduled for elective excision of benign breast fibroadenoma under general anesthesia.
  • Planned airway management with a laryngeal mask airway.
  • American Society of Anesthesiologists (ASA) physical status I-II.
  • Both the SafeLM and LMA Classic are considered clinically appropriate for airway management.
  • Provision of written informed consent.

Exclusion Criteria:

  • Increased risk of pulmonary aspiration, including inadequate preoperative fasting, full stomach, or gastrointestinal obstruction.
  • Known or suspected difficult airway or other airway characteristics for which random allocation between the two study devices is considered clinically inappropriate.
  • Upper airway pathology or anatomical abnormality that may interfere with laryngeal mask placement.
  • Clinical or surgical indication requiring tracheal intubation rather than a laryngeal mask airway.
  • Contraindication or known allergy to medications used in the standardized anesthesia protocol.
  • Inability to provide informed consent.

Waffen und Interventionen

Teilnehmergruppe / Arm
Intervention / Behandlung
Experimental: SafeLM Video Laryngeal Mask

Participants randomized to this arm will receive airway management with the SafeLM video laryngeal mask during general anesthesia for elective fibroadenoma excision. The device will be inserted according to the standardized study protocol.

The SafeLM is a video-assisted supraglottic airway device that allows visualization of the laryngeal structures during insertion and positioning. It will be used for airway management during general anesthesia according to the standardized study protocol.

Aktiver Komparator: LMA Classic

Participants randomized to this arm will receive airway management with the LMA Classic during general anesthesia for elective fibroadenoma excision. The device will be inserted according to the standardized study protocol.

The LMA Classic is a conventional supraglottic airway device without video guidance. It will be used for airway management during general anesthesia according to the standardized study protocol.

Was misst die Studie?

Primäre Ergebnismessungen

Ergebnis Maßnahme
Maßnahmenbeschreibung
Zeitfenster
Oropharyngeal Leak Pressure (OLP)
Zeitfenster: Immediately after successful laryngeal mask placement, before the start of surgery

Oropharyngeal leak pressure will be measured after successful placement of the assigned laryngeal mask and establishment of effective ventilation. OLP will be recorded in cmH2O as the airway pressure at which an audible oropharyngeal leak is detected during a standardized leak test.

Immediately after successful laryngeal mask placement, before the start of surgery
