We experienced a case of fulminant malignant hyperthermia during laparoscopic surgery, which is the first reported case of this kind. A 69-year-old man, weighing 69 kg, underwent laparoscopic colectomy for cecal colon cancer. He had a remarkable familial history of malignant hyperthermia (MH). ⋯ Rise in Paw and arrhythmia turned up frequently as complications of laparoscopic surgery, but they are very similar to the first symptoms of malignant hyperthermia. The decrease in BT with CO2 pneumoperitoneum can mask symptoms of MH. Awareness of this fact is important not to delay the diagnosis.

The endotracheal intubation and laryngeal mask airway confer many advantages for surgical patients. However, a number of problems and complications with airway management by endotracheal intubation and laryngeal mask airway have been documented. In this report, several problems by using endotracheal intubation (e.g. hoarseness, arytenoids dislocation) and laryngeal mask airway (e.g. aspiration, oropharyngeal leak, gastric distension) are summarized.

Maintenance of patent airway has an essential role in respiratory management. The management of difficult airway is one of problems associated with the maintenance of airway patency. "Cannot intubate, cannot ventilate (CICV)" scenario is rare, but it usually leads to serious morbidity and mortality related to anesthesia. ⋯ However, the recent practice of airway management seems to be very complex, depending on the introduction of new airway devices including laryngeal mask airway (LMA). In order to provide the reader with valuable information as to the new devices and airway-associated problems, five experts in this field contributed to this special issue of difficult airway problems.

Review Case Reports
[Cannot intubate, cannot ventilate: airway management of difficult airways in adults].
Cannot intubate, cannot ventilate (CICV) is one major cause of death associated with general anesthesia and thus proper airway management plans are necessary. To achieve safe airway management, it is necessary first to predict if the patient's trachea can be difficult to intubate or the lungs difficult to ventilate. ⋯ To make a right decision, it is necessary to know the advantages and disadvantages of each option, as well as of each airway device, and to be acquainted with these devices during routine anesthesia. In this article, I will present six typical cases of difficult airways, and will discuss appropriate options for safer airway management.

As a variety of new airway devices has been introduced, the practice of airway management has seemingly become more complex. Among them laryngeal mask airway (LMA) is the single most important development in the past 10 years. It has become a commonly accepted device for routine and rescue airway management, and is now listed in the American Society of Anesthesiologists (ASA) Difficult Airway Management Algorithm as an airway and a conduit for tracheal intubation. ⋯ Recent information about standardization work of ISO for rigid laryngoscopes, tracheal tubes and supralaryngeal airway devices are also discussed. Each airway devices has unique properties that may be advantageous in certain situations but disadvantageous in others. Choice and combination of device based on experienced clinical judgment may be crucial to their application.
