Background: A new promising device, the Spritztube (ST), was developed combining the ability to perform both supraglottic ventilation and orotracheal fibreoptic intubation using the same device, allowing an easy passage from supraglottic ventilation to tracheal ventilation avoiding apnea. The present study aims to compare the speed and the subjective ease of insertion of the novel tracheal tube (Spritztube®) compared to the intubating laryngeal mask airway Fastrach™ (FT-LMA) in a simulation environment.
Methods: Each participant received verbal instruction and practical demonstration concerning "technique of insertion" for both devices on manikin and, in a randomized order, used both devices. Time of placement (T1), time of inflation (T2), the elapsed procedural time (T3), ease of insertion, time of exchange maneuver for intubation (T4), success rates and number of attempts were recorded for each EAD.
Results: Forty-seven participants were enrolled. The ST was judged as easier insertion than FT-LMA (P<0.001) having also a significant higher success rate than FT-LMA (P<0.001). Number of attempts for insertion was similar. Number of attempts for exchange to ETI was significantly more for FT-LMA (P<0.001). FT-LMA was applied 11 s faster than the ST (median T3 Fastrach: 13 s, ST: 24 s, P<0.001) as the exchange maneuver for ETI (median T4 FT-LMA: 13 s, ST: 24 s, P<0.001).
Conclusions: In a manikin simulation setting, insertion and intubation with and ST was performed 11 s slower than with use of a FT-LMA.

Perioperative and critical care management following penetrating thoracic trauma represents a complex challenge. Those who survive the early trauma approach and reach the hospital alive often remain in critical condition, with cardiocirculatory complications and major pulmonary injuries. Additional difficulty arises from the presence of a weapon , particularly in a dorsal location, which limits patient positioning, and the safe manipulation of both the weapon and the patient.

Background: The Gastro-Laryngeal Mask (Jcerity Endoscoper Airway) is a new airway management technique utilized in patients undergoing upper gastrointestinal endoscopy surgery under general anesthesia, but evidence of its effectiveness and safety is scarce.
Objective: To assess the success rate of insertion, cardiovascular response, airway pressure, time taken for placement, nausea or vomiting, pharyngodynia, and other complications of using the new type of back-open gastroscopy laryngeal mask.
Methods: We screened 1401 patients; 105 were ineligible, and 40 declined to participate.

Background: Ciprofol, a novel intravenous anesthetic, exhibits similar sedation mechanisms and pharmacokinetic properties to propofol. However, ciprofol demonstrates greater potency and is associated with reduced injection pain compared to propofol. Given the varying sensitivities to anesthetic agents across different age groups, this study aims to determine the median effective dose (ED) of ciprofol required to suppress the laryngeal mask airway (LMA) insertion response in both young and older adult patients, as well as to assess its potential adverse reactions.

Background And Objective: The CyberKnife® is a robotic stereotactic radiosurgery system designed for non-invasive treatment of tumor lesions. Some of these procedures are performed under sedation or general anesthesia, depending on the patient and the lesion being treated. The objective of this study is to describe the anesthetic management and postoperative outcomes of patients treated with CyberKnife® radiosurgery at a reference center for neurosurgery in the city of Medellín, Colombia.

The flow-volume loop (FVL) is a valuable yet often underutilized tool for assessing the placement of the laryngeal mask airway (LMA) during surgery. It provides real-time graphical data on airway patency and ventilation. These cases examine the role of FVL in identifying LMA misplacement.
