An observational study in Airway Complication of Anesthesia, sponsored by Aga Khan University. Recruiting at 1 site in Pakistan. Open to participants aged 2 Years to 10 Years. Per ClinicalTrials.gov, last updated 2024-03-18.
Sponsored by Aga Khan University · Observational
Laryngeal Mask Airway has been used in paediatric anaesthesia since the 1990's. Clinical practice in paedeatric anaesthesia for Laryngeal Mask Airway removal varies and there is no standard of care.
In children removing the Laryngeal Mask Airway under deep inhalational anaesthesia has some advantages compared to awake, but may be associated with higher rate of complications when Laryngeal Mask Airway is removed in supine compared to lateral position. On the other hand deep anaesthesia may cause airway obstruction due to reduction in tone of upper airway muscles in some patients. An oropharangeal airway may prevent this. This aspect had not been studied before and represent a gap in literature.
Study Hypothesis:
Airway complications associated with Laryngeal Mask Airway removal under deep anaesthesia are same with or without insertion of an oral airway. Alternate hypothesis is that airway complications be less if an air way is inserted at the end of anaesthesia.
Objective:
The present study was designed to observe any difference in immediate complication after removal of LMA in supine head down position under deep anaesthesia with or without insertion of an oro-pharyngeal airway. Airway complications that we will observe are desaturation \<92%, stridor, excessive secretions, laryngospasm, retching, vomiting, coughing, trauma to the soft tissues and damage to the teeth.
Aga Khan University is the lead sponsor of 290 studies on the registry; 44 are open to participants now.
Counted across the registry records on this site, refreshed daily.
Children aged 2-10 years undergoing surgery where anaesthesia with Laryngeal Mask Airway insertion.
Exclusion Criteria:
An appropriate size oropharyngeal airway (GUEDEL) will be inserted immediately after removal of LMA and time will be noted. (Size will be chosen by placing the flange at the corner of the mouth and tip at the angle of the jaw).
Other: GUEDEL Airway
In Group B No oropharyngeal airway (GUEDEL) will be inserted.
GUEDEL Airway of size '000,00,0,' and '1' will be used.
Oxygen saturation
Oxygen saturation \<92% will be considered as complication
Time frame: Day 1
Stridor
The presence of noisy breathing occurring through obstructed airflow. We clinically measure it by auscultation of the nose, oropharynx, neck and chest.
Time frame: Day 1
laryngospasm
The occurrence of a transient and reversible spasm of the vocal cords. We will evaluate laryngospasm by observing a high pitch inspiratory stridor followed by partial or complete airway obstruction.
Time frame: Day 1
