OBJECTIVE: Esophago-gastro-duodenoscopy (EGD) was performed under the topical anesthesia of the pharynx. However spraying lidocaine was found to be an annoying maneuver to patients, while nebulized lidocaine appeared to efficiently suppress gags and cough reflexes in airway anesthesia. This study aimed to compare the effectiveness of spraying and nebulized lidocaine for patients undergoing EGD. MATERIAL AND METHOD: A total of 110 patients undergoing elective EGD, with a history of neither lidocaine intolerance nor irritable airways due to smoking, chronic obstructive pulmonary disease (COPD), upper respiratory infection, asthma, cardiac and pulmonary diseases and allergy to lidocaine were included...

Corneal anesthesia is a debilitating condition which can ultimately lead to blindness from repetitive corneal injury and scarring. We have developed a minimally invasive technique for corneal re-innervation that we have used with excellent results in ten eyes. This article and accompanying video describes the relevant anatomy and demonstrates the technique in detail.

OBJECTIVES: Screening decreases colorectal cancer (CRC) mortality. The national press has scrutinized colonoscopy charges. Little systematic evidence exists on colorectal testing and payments among commercially insured persons. Our aim was to characterize outpatient colorectal testing utilization and payments among commercially insured US adults. METHODS: We conducted an observational cohort study of outpatient colorectal test utilization rates, indications, and payments among 21 million 18-64-year-old employees and dependants with noncapitated group health insurance provided by 160 self-insured employers in the 2009 Truven MarketScan Databases...

Pediatric patients often undergo anesthesia for ambulatory procedures. This article discusses several common preoperative dilemmas, including whether to postpone anesthesia when a child has an upper respiratory infection, whether to test young women for pregnancy, which children require overnight admission for apnea monitoring, and the effectiveness of nonpharmacological techniques for reducing anxiety. Medication issues covered include the risks of anesthetic agents in children with undiagnosed weakness, the use of remifentanil for tracheal intubation, and perioperative dosing of rectal acetaminophen...

Infections of the upper respiratory tract ( URI) are the most common preoperative encountered comorbidity in childhood. Whether anesthesia for a child with respiratory infection should be performed or better be canceled, is still a dilemma for many anesthetists. The reasons for this are understandable: respiratory infections are associated with an increased incidence of perioperative respiratory adverse events, and there have been no evidence-based recommendations for the procedure in the individual case. The reason appears to be the asthma-like airway hyperreactivity...

We develop a particle filter algorithm to simultaneously estimate and track the instantaneous peak frequency, amplitude, and bandwidth of multiple concurrent non-stationary components of an EEG signal in the time-frequency domain. We use this method to characterize human EEG activity during anesthesia-induced unconsciousness.

Fever and upper respiratory tract infections (URI) are frequently-encountered preoperative comorbidities. Whether or not to proceed with anesthesia for a child with common cold is still a continuing dilemma for anesthesiologists. We, anesthesiologists often feel uncomfortable in making a decision whether or not to proceed because URI is associated with perioperative respiratory adverse events (PRAEs) and there are no definite rules to proceed with or postpone a case. Most of PRAEs are easily managed by experienced hands; however, laryngospasm or bronchospasm without early detection and immediate treatment would probably result in serious sequelae...

BACKGROUND: Active upper respiratory tract infection (URI), orotracheal intubation and use of inhalation anesthetics are known risk factors for perioperative respiratory adverse events (RAE). This study investigated the risk factors of perioperative RAE in children with these risk factors. METHODS: The records of 159 children who underwent general anesthesia with an orotracheal tube and inhalation were reviewed. These patients also had at least one of the following URI symptoms on the day of surgery: clear or green nasal secretion, dry or moist cough, nasal congestion, or fever...

The major adaptations of the maternal cardiovascular system that progress throughout gestation may unmask previously unrecognized heart disease and result in significant morbidity and mortality. Most of these changes are almost fully reversed in the weeks and months after delivery. Hemodynamic changes during pregnancy include increased blood volume, cardiac output (CO), and maternal heart rate; decreased arterial blood pressure; decreased systemic vascular resistance. CO increases up to 30% in the first stage of labor, primarily because of increased stroke volume; maternal pushing efforts in the second stage of labor can increase CO by as much as 50%...

Pharyngeal collapsibility during sleep is believed to increase due to a decline in dilator muscle activity. However, genioglossus electromyogram (EMG) often increases during apnoeas and hypopnoeas, often without mechanical effect. 17 patients with obstructive sleep apnoea were anaesthetised and evaluated from termination of propofol administration to awakening. Genioglossus EMG, flow and pharyngeal area (pharyngoscopy) were monitored. Prolonged hypopnoeas enabled evaluation of the relationships between genioglossus EMG and mechanical events, before and after awakening...

BACKGROUND: The use of procedural sedation and analgesia to allow painful orthopaedic manipulations in the emergency department has become a standard practice over the last decade. Both propofol and midazolam/ketamine are attractive sedative regimens for routine use in the emergency department. We hypothesized that sedation with propofol as compared with midazolam/ketamine will save time in the emergency department. The purpose of the present study was to compare the recovery time, the total sedation time, and the adverse events of procedural sedation and analgesia induced with propofol as compared with midazolam/ketamine...
