Insights

Postoperative sore throat in children was similar between the Ambu laryngeal mask and I-gel airway devices. This study found no significant difference in sore throat frequency or severity between the two airway devices in pediatric patients.

Area of Science:

  • Anesthesiology
  • Pediatric Surgery
  • Airway Management

Background:

  • Postoperative sore throat is a common complaint in children after general anesthesia.
  • Laryngeal mask airways are frequently used for airway management in pediatric surgery.
  • Comparing different airway devices is crucial for optimizing patient outcomes.

Purpose of the Study:

  • To compare the severity and frequency of postoperative sore throat in children using Ambu laryngeal mask airway versus I-gel®.
  • To evaluate patient-reported outcomes regarding sore throat after elective surgery.

Main Methods:

  • Seventy children (6-16 years) undergoing elective surgery were randomly assigned to Ambu laryngeal mask or I-gel®.
  • Patients were interviewed postoperatively at 0, 1, 6, and 24 hours by a blinded observer.
  • Data collected included self-reported sore throat severity and frequency.

Main Results:

  • No statistically significant difference in the incidence of postoperative sore throat between the Ambu Group and I-gel Group at any time point (p > 0.28).
  • Insertion duration was shorter for the Ambu laryngeal mask, while I-gel® was easier to insert (p=0.029).
  • I-gel® demonstrated a higher oropharyngeal seal pressure than the Ambu laryngeal mask (p=0.001).

Conclusions:

  • The choice between Ambu laryngeal mask and I-gel® does not significantly impact the severity or frequency of postoperative sore throat in children.
  • Both devices are viable options for airway management in pediatric surgery, with considerations for insertion ease and seal pressure.

Suctioning the Oropharyngeal Airway

In preparing for oropharyngeal airway suctioning, a nurse must gather all necessary equipment, including a suction unit with tubing, a prepackaged suction kit, sterile gloves, water or saline for irrigation, a water-soluble lubricant, and additional personal protective equipment (such as a gown, mask, and goggles) to control infections.
After assembling the equipment, the nurse should practice hand hygiene and don appropriate PPE according to infection control guidelines to avoid the...

Suctioning the Nasopharyngeal Airway

Nasopharyngeal suctioning is a procedure to remove secretions from the upper part of the respiratory tract that the patient cannot clear independently. It helps maintain airway patency and prevents complications such as aspiration pneumonia.

Cardiopulmonary Resuscitation V: Advanced Airway Management Techniques

Airway management is essential in emergency and surgical medicine, ensuring ventilation and oxygenation in patients who cannot maintain their own airway. Clinicians use a range of techniques and devices to secure the airway, depending on the patient’s condition and the clinical context. Key methods include endotracheal intubation, rapid sequence intubation (RSI), supraglottic airway devices, and advanced visualization aids. In cases where these approaches fail, surgical airway...

Tracheostomy: Procedure and Tubes01:28

Tracheostomy: Procedure and Tubes

A tracheostomy is a surgical procedure that creates an artificial opening into the trachea, typically at the second or third cartilaginous ring level. This opening allows the insertion of a tracheostomy tube, which can replace an endotracheal tube, provide mechanical ventilation, bypass an upper airway obstruction, or remove accumulated tracheobronchial secretions.
Tracheostomy tubes can be made of semiflexible plastic (polyurethane or silicone), rigid plastic, or metal, and they come in...
