NCT06101407

Brief Summary

This observational study included consecutive MG patients who underwent thoracoscopic thymectomy with Univent tube intubation under general anesthesia without NMBAs and combined with airway topical anesthesia between January 2016 and December 2019. The investigators focus on intubation conditions, surgical conditions, intraoperative respiratory, and airway complications

Outcome Measures

Primary Outcomes (7)

  • Rate of laryngoscopy difficulty

    Laryngoscopy difficulties are categorized as: * easy * fair * difficult

    During surgery

  • Rate of vocal cord position

    Vocal cord positions are categorized as: * abducted * intermediate/moving * closed

    During surgery

  • Rate of reaction to tracheal tube insertion and cuff inflation

    Reaction to tracheal tube insertion and cuff inflation are evaluated based on diaphragmatic movement/coughing and categorized as: * none * slight * vigorous/sustained

    During surgery

  • Rate of intubation conditions

    Intubation conditions are categorized as: * excellent * good * poor

    During surgery

  • Neuromuscular transmission at intubation time.

    Neuromuscular transmission was measured using TOF value (%) at intubation time.

    During surgery

  • Rate of lung collapse

    During the surgical procedure, After opening the pleura and directly examining the quality of lung collapse as follows: 1. \- spontaneous 2. \- assisted with suction 3. \- manual

    During surgery

  • Rate of surgical conditions

    The surgical conditions, as evaluated by surgeons and categorized as: 1. \- excellent (complete collapse with perfect surgical exposure) 2. \- fair (total collapse, but the lung still has residual air) 3. \- poor (no collapse or partial collapse with interference in surgical exposure)

    During surgery

Secondary Outcomes (4)

  • Rate of vocal cord injuries

    After anesthesia emergence and up to 3-day post-surgeries or until complete resolution.

  • Rate of bronchial injuries

    After anesthesia emergence and up to 3-day post-surgeries or until complete resolution.

  • Rate of postoperative sore throat

    After anesthesia emergence and up to 3-day post-surgeries or until complete resolution.

  • Rate of postoperative hoarseness

    After anesthesia emergence and up to 3-day post-surgeries or until complete resolution.

Study Population

MG patients who underwent thoracoscopic thymectomy under general anesthesia without NMBAs using Univent tube. MG was definitively diagnosed based on clinical features, electromyography results, and/or circulating antibodies against acetylcholine receptors and classified according to the Osserman Classification

You may qualify if:

  • Myasthenia gravis patients
  • Undergoing thoracoscopic thymectomy
  • Undergoing general anesthesia
