mechanical ventilation which terms “apneic oxygenation”. Preoxygenation Preoxygenation is the administration of oxygen before the induction of general anesthesia and airway management. In 2003 guidelines from the American Society of Anesthesiologists Task Force on the Management of the Difficult Airway recommended “face mask preoxygenation

Induction of anesthesia and MV evaluation. An anesthesiologist with more than 3 years of experience was assigned to airway management. During induction of anesthesia the patient’s head and neck were placed in a sniffing position. Preoxygenation of each patient was performed for 4 min by mask with 100% O 2.

Mask or supraglottic airway ventilation — After induction of anesthesia in the patient with a difficult airway mask ventilation should be established with 100 percent oxygen. Successful facemask ventilation depends on both patient factors and the skill of the clinician.

Accordingly an increase in pressure from gastric insufflation during face mask ventilation may translate to an increased aspiration risk by reflex relaxation of the UES and LES. Many pieces of information regarding the response of the gastroesophageal conduit to gastric insufflation during anesthesia induction are currently missing and further

Jul 30 2020· Effective mask ventilation (MV) is essential for safe airway management during general anesthesia (GA). MV is a fundamental airway management skill for providing oxygen to a conscious obtunded or unconscious patient and can be lifesaving in situations where the placement of a secure airway device proves challenging.

Methods: In this prospective randomized double-blind study patients were allocated to one of the two groups (P10 P15) defined by the inspiratory pressure applied during controlled-pressure ventilation: 10 and 15 cm H 2 O. Anesthesia was induced using propofol and sufentanil; no neuromuscular-blocking agent was administered. Once loss of eyelash reflex …

Mask ventilation (MV) is a pivotal procedure used to deliver oxygen during the induction of general anesthesia before a secure airway with a tracheal tube or supraglottic airway device can be established. Difficult mask ventilation (DMV) may cause hypoxic tissue injury resulting in morbidity and mortality related to anesthesia.

tic pressure-controlled ventilation versus manual circle system face-mask ventilation regarding ventilatory variables in an unprotected airway. We studied 41 adults (ASA status I–II) in a prospective randomized crossover design with both devices during the induction of anesthesia. Respiratory variables were measured with a pulmonary monitor (CP-100). …

Langeron et al reported that in 17% of cases. Asai et al reported that in 57% of patients in whom ventilation through a face mask was difficult no airway problems had been anticipated before induction of anesthesia. In our study muscle relaxant was used in all the patients involved in study as previously reported by Rose and Cohen.

Background: Face mask ventilation (FMV) during induction of anaesthesia is associated with risk of gastric insufflation that may lead to gastric regurgitation and pulmonary aspiration. A continuous positive airway pressure (CPAP) has been shown to reduce gastric regurgitation. We therefore hypothesised that CPAP followed by FMV with positive end-expiratory pressure …
