Abstract

Insights

This study found no significant difference in postoperative sore throat incidence between trainee anesthetists using video laryngoscopes (VDL) and conventional Macintosh laryngoscopes (CL). Laryngoscope technique and training may influence postoperative sore throat (POST) outcomes.

Area of Science:

  • Anesthesiology
  • Surgical Complications
  • Airway Management

Background:

  • Postoperative sore throat (POST) is a frequent complication following endotracheal intubation.
  • The choice of laryngoscope may influence the incidence of POST.

Purpose of the Study:

  • To compare the incidence of POST in patients intubated by trainee anesthetists using a Video Laryngoscope (VDL) versus a Conventional Macintosh Laryngoscope (CL).

Main Methods:

  • 110 patients undergoing elective laparoscopic cholecystectomy were randomized into CL or VDL groups.
  • Postoperative sore throat was assessed using a visual analogue scale at 1, 12, and 24 hours.
  • Standardized anesthetic protocols were applied to all participants.

Main Results:

  • No significant difference in POST incidence was observed between the CL and VDL groups at 1, 12, or 24 hours post-intubation.
  • Demographics, intubation time, and complications were similar across both groups.
  • At 24 hours, POST incidence was 25% for CL and 16% for VDL (p=0.669).

Conclusions:

  • Trainee anesthetists using VDL or CL did not show a significant difference in POST incidence.
  • Objective evidence suggests laryngoscope technique and training impact POST outcomes.

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 Suctioning II: Procedure

Tracheostomy suctioning is a vital nursing procedure that involves removing secretions from the tracheostomy tube to maintain airway patency and prevent respiratory complications. Nurses need to understand the proper technique for tracheostomy suctioning to ensure patient safety and comfort. In this guide, we will outline the step-by-step process for performing tracheostomy suctioning, including preparing the sterile field, donning personal protective equipment (PPE), lubricating and connecting...

Tracheostomy Care II: Procedure

Tracheostomy care is an essential nursing skill that involves cleaning and maintaining a tracheostomy tube to prevent infection and other complications. Here's a step-by-step guide explaining each procedure with its rationale. Note that disposable gloves are to be worn at all times and changed as often as needed to maintain a sterile work environment, and to protect both patient and healthcare worker.
Step 1: Perform hand hygiene, and put on personal protective equipment: gown, gloves, mask...

Endotracheal Intubation II: Nursing Management

Endotracheal intubation is a critical procedure that can be lifesaving for many patients with respiratory distress or failure. The role of nursing in managing endotracheal tubes is pivotal, as it involves pre-intubation preparation, assisting during the procedure, and post-extubation care.
1. Nursing Care of Patients Before Intubation
Before the endotracheal intubation procedure, nurses play an essential role in ensuring the process goes smoothly. The nurses must be familiar with intubation...

Endotracheal Intubation I: Procedure

Endotracheal or ET intubation is a critical medical procedure used to secure a patient's airway, often in acute respiratory distress, apnea, upper airway obstruction, ineffective clearance of secretions, high risk for aspiration, or during general anesthesia.
The ET tube comprises various components, including a standard adaptor to attach a bag-valve-mask (BVM) or ventilator, a cuff, a pilot balloon, and radiopaque markings along its length to measure the insertion distance. The tube sizes...

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...
