REVIEW
Robert C Bosack
Parenteral medications are titrated in the oral and maxillofacial surgery office to achieve moderate sedation, deep sedation, or general anesthesia while continuously maintaining spontaneous ventilation with an open airway. After initial drug administration, the provider assesses and interprets both the level of anesthesia and the presence/severity of adverse side effects, both of which guide further drug titration, cessation, reversal, or medical management. This assessment is called monitoring, which guides the conduct of anesthesia delivery and becomes the essence of this art...

BACKGROUND: Difficult or impossible face mask ventilation complicated with difficult tracheal intubation during anesthesia induction occurs in 0.4% of adult anesthesia cases, possibly leading to life-threatening complications. Because of such catastrophes, muscle relaxants have been recommended to be administered after confirming adequate face mask ventilation without a solid scientific validation of this principal. METHODS: In this observational study, the ease of ventilation and the scores of direct laryngoscopy views before and after administration of cisatracurium were assessed in ninety young healthy adults, without anesthetic risks and without foreseen difficult intubation and who were scheduled for general elective surgeries...

Obstructive sleep apnea (OSA) is the leading sleep disordered breathing condition, with a prevalence rate of moderate to severe OSA of approximately 10 - 17% in the general population. Its prevalence in the surgical population seems to be higher. However, a proportion of up to 60% of patients may not have a formal diagnosis at the moment of preoperative visit. OSA is associated with a number of comorbidities and increased perioperative risks. However, most interventions for the perioperative management of OSA patients lack high quality evidence...

OBJECTIVE: Poor sleep quality is emerging as high prevalence among the patients suffering from cardiometabolic disturbances. The vascular polypeptide endothelin 1 (ET-1) is involved in many of the health disorders. However, its potential involvement in patients having poor sleep quality along with cardiovascular problem is limited. The present study was formulated to conduct a prospective analysis of the relationship between ET-1 and in hospital outcome in sleep disorder patients undergoing routine coronary artery bypass grafting (CABG)...

BACKGROUND: Transnasal Humidified Rapid-Insufflation Ventilatory Exchange has been shown to safely prolong the safe apnea time in well children post induction of anesthesia and is rapidly becoming a new standard for apneic oxygenation in adults. The same oxygenation technique is described as nasal high flow and can be used in infants and children at risk of apnea during anesthesia. AIM: We investigated the use of nasal high flow oxygen delivery during anesthesia in children with abnormal airways requiring tubeless airway assessment or surgery...

Neostigmine has been traditionally used as the agent of choice to reverse Neuromuscular Blockade (NMB) after muscle paralysis during general anesthesia. However, the use of neostigmine has not been without untoward events. Sugammadex is a novel drug that selectively binds to aminosteroid nondepolarizing muscle relaxants and reverses even a deep level of NMB. Controversy exists regarding the optimal dose of sugammadex that is effective in reversing the NMB after the incomplete reversal with neostigmine and glycopyrrolate...

BACKGROUND: Clinicians frequently assume that during arterial puncture for measuring arterial blood gases patients hyperventilate from pain and anxiety. This assumption leads clinicians to falsely interpret a PaCO2 and pH near the upper limit of normal as a chronic respiratory acidosis corrected by an acute respiratory alkalosis. OBJECTIVE: Determine if participants hyperventilate during arterial puncture from pain and anxiety. METHODS: We recruited participants from a pulmonary function laboratory referred for arterial blood gas measurement...

BACKGROUND: Traditionally, mechanical ventilation is achieved via active lung inflation during inspiration and passive lung emptying during expiration. By contrast, the novel FLEX (FLow-controlled EXpiration) ventilator mode actively decreases the rate of lung emptying. We investigated whether FLEX can be used during intraoperative mechanical ventilation of lung-healthy patients. METHODS: In 30 adult patients scheduled for neurosurgical procedures, we studied respiratory system mechanics, regional ventilation, oxygenation, and hemodynamics during ventilation with and without FLEX at positive end-expiratory pressure (PEEP) of 5 and 7 cm H2O...

BACKGROUND: In the last year there has been an increasing interest for using frailty scales for risk stratification of elderly patients undergoing major surgery. We planned to compare two frailty scales with risk scales already used in cardiac surgery, to study which of these scores have better prognostic value predicting postoperative outcome in open heart surgery. METHODS: We conducted a prospective clinical trial, including 57 patients over 65 years. We calculated Cardiac Anesthesia Risk Evaluation score, EuroScore II, Clinical Frailty Scale, Edmonton Frail Scale for each patient and followed the postoperative complications, length of mechanical ventilation, length of stay in the intensive care unit and hospital, and in-hospital death related to these risk and frailty scores...

Gastroschisis is a congenital anomaly characterized by a defect in the anterior abdominal wall with protrusion of abdominal viscera. Perioperative mortality is very high in these patients. Traditionally gastroschisis repair has been performed under general anesthesia with endotracheal intubation, requiring postoperative intensive care admission and mechanical ventilation. Caudal block is an attractive alternative to general anesthesia. We present a series of three neonates with gastroschisis, repaired solely under caudal anesthesia...

Inhalants are commonly used to anesthetize reptiles, but volatile anesthetics have been associated with prolonged recovery times. The objective of this study was to determine the effects of intramuscular (IM) epinephrine on anesthetic recovery times following isoflurane anesthesia in a population of subadult American alligators ( Alligator mississippiensis ). In this prospective randomized crossover study, five clinically healthy alligators were anesthetized for 90 min with the use of isoflurane. Alligators were randomly assigned into one of two treatment groups: Group E received IM epinephrine (0...

BACKGROUND: Mask ventilation is routinely performed during anesthesia. Under some circumstances, it might be difficult to perform, such as in edentulous patients, due to inadequate mask seal. We developed a new device called NIPARA and studied its use For ventilation optimization in edentulous patients. METHODS: This randomized controlled trial included edentulous adults who had no other predictors of difficult airway, scheduled to undergo general anesthesia. Patients were assigned either to the NIPARA device group or to the control group (oral airway only)...
