The use of gamification in healthcare has been gaining popularity. This prospective, randomized, clinical trial was designed to evaluate whether gamification of the preoperative process—via virtual reality (VR) gaming that provides a vivid, immersive and realistic experience—could reduce preoperative anxiety in children. Seventy children scheduled for elective surgery under general anesthesia were randomly divided into either the control or gamification group. Children in the control group recei

The prophylactic use of 0.2 mg/kg of dexamethasone significantly decreases the incidence and severity of sore throat and hoarseness 1 h and 24 h after tracheal extubation of a DLT.

BACKGROUND AND AIMS: An immersive virtual reality tour of the operating theater could reduce preoperative anxiety. This study was designed to determine whether a preoperative immersive virtual reality tour demonstrates a reduction in emergence delirium through reducing the preoperative anxiety in children undergoing general anesthesia. METHODS: Eighty-six children were randomly allocated into either the control or virtual reality group. The control group received conventional education regarding

Virtual reality (VR), a technology that provides a stimulated sensory experience, has recently been implemented in various fields of medicine. Several studies have investigated the efficacy of VR on preoperative anxiety. The purpose of this meta-analysis was to validate whether VR could relieve preoperative anxiety in patients undergoing surgery. Electronic databases were searched to identify all randomized controlled trials (RCTs) investigating the effect of VR on preoperative anxiety. The prim

The PLMA showed significantly lower oropharyngeal leak pressures than did the LTS or CobraPLA in the neck extension and rotation positions. Caution is warranted when changing the position of the head and neck when using the Cobra-PLA or LTS as gastric insufflation or ventilatory difficulty may occur.

The present study could be used for the establishment of a database for genetic counseling. The discovery of an abnormality provides the option of termination or continuation in the pregnancy, a more suitable obstetric management in Korea.

BACKGROUND: Ischemia and the following reperfusion damage are critical mechanisms of spinal cord injury. Statins have been reported to decrease ischemia-reperfusion injury in many organs including the spinal cord. Anti-oxidative effect is one of the main protective mechanisms of statin against neuronal death and cytotoxicity. We hypothesized that statins' anti-oxidative property would yield neuroprotective effects on spinal cord ischemia-reperfusion injury METHODS: Primary cultured spinal cord m

BACKGROUND: During laparoscopic gynecologic surgery, pneumoperitoneum combined with the Trendelenburg position moves the carina towards the tip of the endotracheal tube (ETT), decreasing the margin of safety for the ETT position and increasing accidental endobronchial intubation. However, it remains to be established whether the tracheal length itself is actually changed. We conducted a prospective observational study to measure the change in the length of the trachea and the distance between th

Positioning the ETT by auscultation places the ETT more deeply than the midtrachea, which can increase the risk of endobronchial intubation during neck flexion.

본 연구는 TV 프로그램 속의 PPL에 대한 소비자들의 인식 및 태도와 PPL이 소비자들에게 미치는 영향력을 분석하고자 한다. 이를 위해 PPL의 부정적ㆍ긍정적 측면에 대한 소비자들의 인식과 태도를 알아보았고, PPL이 소비자에게 미치는 영향력을 인지도, 선호도, 구매의도로 나누어 분석하였다. 연구 결과 소비자들의 PPL에 대한 인식수준은 부정적인 면 뿐만 아니라 긍정적인 면에 대해서도 높은 인식 수준을 보이는 것으로 나타났다. 그리고 약간의 차이지만 소비자들은 PPL의 부정적 측면에 대해 보다 높게 인식하고 있었다. 또한 드라마 내에서 PPL로 인한 간접광고는 소비자에게 분명한 영향력을 행사하고 있었으며, 집단 간에 유의한 차이가 나타남을 알 수 있었다. TV 방송의 공공성과 공익성을 생각할 때 PPL은 특정업체가 광고시간이 아닌 프로그램 내에서 자사의 제품을 광고함으로써 불공정한 이익을 취하는 것이라 할 수 있다. 이러한 간접광고는 소비자의 시청권을 침해하고 바람직하지 못한 소비

During fibreoptic intubation, it is often difficult to advance a tracheal tube over the fibreoptic bronchoscope. We performed a prospective randomised study to investigate the effect of the jaw-thrust manoeuvre on the ability to advance a tracheal tube during oral fibreoptic intubation. After placing the bronchoscope in the trachea, an assistant randomly applied a jaw-thrust manoeuvre (jaw-thrust group) or sham manoeuvre (control group) in 82 patients during tube advancement. The jaw-thrust grou

Neurotoxic effects of local anesthetics (LAs) on developing motor neurons have not been documented. We investigated the neurotoxic effects of LAs on developing motor neurons in terms of cell viability, cytotoxicity, reactive oxygen species (ROS), and apoptosis. Embryonic spinal cord motor neurons were isolated from Sprague-Dawley rat fetuses and exposed to one of the three LAs-lidocaine, bupivacaine, or ropivacaine-at concentrations of 1, 10, 100, or 1000 µM. The exposure duration was set to 1 o

BACKGROUND: During induction of general anesthesia, proper mask ventilation is crucial for supplying sufficient oxygen to unconscious patients. Midazolam has a relaxing effect on airway muscles. We hypothesized that sedative premedication with midazolam would facilitate mask ventilation during anesthetic induction. METHODS: Patients undergoing elective surgery under general anesthesia were randomized into 2 groups. The midazolam group received midazolam premedication at the reception area, 3 min
