    A 67-year-old woman suffering from hoarseness or dysphagia was diagnosed with motor neuron disease. She was scheduled for laparoscopic cholecystectomy under general anesthesia for suspected gallbladder cancer. She was concerned about the exacerbation of her hoarseness or dysphagia from tracheal intubation. We therefore decided to perform airway management by using supraglottic device air-Q blocker, through which a gastric tube could be inserted. We first passed the gastric tube through the outer blocker hole and inserted it into the esophagus using Magill forceps. The air-Q blocker was placed position under the guidance of a McGrath videolaryngoscope. Sealing pressure was over 20 cmH2O and mechanical ventilation was performed uneventfully during artificial pneumoperitoneum. We were able to deflate the stomach and perform tracheal suction via the inner hole of the air-Q. Following the operation, the patient developed neither hoarseness nor pharyngeal pain.

    Cardiopulmonary Resuscitation II: ACLS Airway Management

    Airway management is a key skill in emergency and critical care settings, as maintaining a clear airway is essential for adequate oxygenation and ventilation.Head Tilt-Chin Lift TechniqueThe head tilt-chin lift maneuver is an essential technique primarily used in patients without suspected cervical spine injuries. To perform this maneuver, one hand is placed on the patient’s forehead, and gentle pressure is applied backward to tilt the head. The fingertips of the other hand are positioned...

    Skeletal Muscle Relaxants: Therapeutic Uses

    Skeletal muscle relaxants are used to relax muscle tone and alleviate painful muscle contractions. However, the choice of skeletal muscle relaxants depends on the duration of the surgical procedure in order to minimize potential side effects. Skeletal muscle relaxants like neuromuscular blocking agents [NMBAs] are commonly employed as adjuvants alongside general anesthetics in clinical settings. NMBAs are also used to maintain controlled ventilation during surgery of the larynx or pharynx...

    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...

    Nondepolarizing (Competitive) Neuromuscular Blockers: Pharmacological Actions

    Nondepolarizing neuromuscular blockers prevent the membrane depolarization of muscle cells and inhibit muscle contraction. These are usually administered with anesthetics to achieve complete muscle relaxation. Upon administration, these drugs first block the small, rapidly contracting muscles of the face and hands, followed by the larger muscles of the trunk and the intercostal muscles. The diaphragm is the last muscle to be affected.
    Although all competitive neuromuscular blockers are designed...

    Depolarizing Blockers: Pharmocokinetics

    Depolarizing blockers are administered through intravenous injection. Succinylcholine is the most common choice of depolarizing blockers in emergency clinical practices. Although they have a rapid onset, they readily diffuse away from the motor end plate into the extracellular fluid. They are metabolized by enzymes such as liver butyrylcholinesterase and plasma pseudocholinesterases. This produces a short duration of action, typically 5-10 minutes long, unlike nondepolarizing blockers, which...

    Suctioning the Nasopharyngeal Airway01:29

    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.
