Hemodynamic changes following injection of local anesthetics with different concentrations of epinephrine during simple tooth extraction: A prospecti…

2015

Background Presence of epinephrine in local anesthetic cartridge increases the duration of local anesthesia (LA), decreases the risk of toxicity, and provides hemostasis. However, the unfavorable effects are increasing heart rate (HR) and raising blood pressure (BP). The aim was to evaluate hemodynamic changes in the BP, HR, and oxygen saturation (SpO2) of normal patients undergoing tooth extraction using LA with various epinephrine concentrations. Material and Methods A prospective randomized clinical trial was conducted on 120 patients who were divided randomly into 3 parallel groups according to the LA received. Group 1: lidocaine 2% with epinephrine 1:80,000 (L80). Group 2: articaine 4%…

Comparison of anesthetic efficacy of 4% articaine with 1:100,000 epinephrine and 2% lidocaine with 1:80,000 epinephrine for inferior alveolar nerve b…

2014

Objectives: This study was done to compare the anesthetic efficacy of 4% articaine with 1:100,000 epinephrine with that of 2% lidocaine with 1:80,000 epinephrine during pulpectomy in patients with irreversible pulpitis for inferior alveolar nerve block in mandibular posterior teeth. Material and Methods: Patients with irreversible pulpitis referred to the Department of Conservative Dentistry and Endodontics, K.D. Dental College, randomly received a conventional inferior alveolar nerve block containing 1.8 mL of either 4% articaine with 1:100,000 epinephrine or 2% lidocaine with 1:80,000 epinephrine. After the patient's subjective assessment of lip anesthesia, the absence/presence of pulpal …

Comparation of the eutectic mixture of lidocaine/prilocain versus benzocaine gel in children

2011

Objective: To compare the anesthetic effect of a non commercial eutectic mixture of 4% lidocaine/ prilocaine (PLO 4%) and 20% benzocaine gel (Hur- ricaine®), as topical anesthetic, prior to inferior al- veolar nerve block and buccal infiltration anesthesia in 5 - 12 year old children. Study design: Infiltrative anesthesia was applied in 50 children, divided in two groups (n = 25) using PLO 4% and Hurricaine® as topical anesthesia prior to infiltration. Physical reac- tions were registered using the Sound-Eyes- Motor Scale. Physiological changes expressed by ar- terial pressure and heart rate. Subjective pain re- sponse was scored on a Facial Image Scale. Physical physiological and subjectiv…

Topical Airway Anesthesia for Awake-endoscopic Intubation Using the Spray-as-you-go Technique with High Oxygen Flow

2017

A patient's willingness to cooperate is an absolute precondition for successful awake intubation of the trachea. Whilst drug-sedation of patients can jeopardize their spontaneous breathing, topical anesthesia of the airway is a popular technique. The spray-as-you-go technique represents one of the simplest opportunities to anesthetize the airway mucosa. The application of local anesthetic through the working channel of the flexible endoscope is a widespread practice for anesthetists as well as pulmonologists. There is neither need for additional devices nor special training as a pre-requisite to perform this technique. However, a known clinical problem is the coughing and gagging reflex tha…

P-71ADOLESCENT ETHANOL EXPOSURE INDUCES LONG-TERM MEMORY DEFICITS AND POTENTIATES THE MEMORY IMPAIRMENT INDUCED BY COCAINE WITHDRAWAL IN ADULT MICE

2015

Ethanol (EtOH) heavy-binge drinking during pubertal development elicits long-lasting neurobehavioral alterations in the adulthood such as memory impairments. An early history of EtOH consumption is correlated with higher rates of cocaine addiction in the adulthood. One consequence of cocaine withdrawal is the induction of memory deficits. The aim of the present investigation was to study the consequences of adolescent exposure …

Refractory Death Rattle: Deep Aspiration Facilitates the Effects of Antisecretory Agents

2011

Anticholinergic drugs, including atropine, hyoscine butylbromide, and scopolamine, have been shown to be equally effective in the treatment of death rattle. However, anticholinergic drugs may only be effective in reducing the production of further secretions, rather than eliminating the existing ones. A case is described in which a preventive procedure was undertaken to carefully eliminate secretions before starting anticholinergic drugs. Airway aspiration under light anesthesia removed secretions before starting anticholinergic drugs. Low doses of propofol were given intravenously to make a laryngoscopy feasible, allowing the complete aspiration of large amounts of tracheal secretions. No …

Physiologie und Pathophysiologie des respiratorischen Systems

2006

Positive pressure ventilation in children is associated with problems similar to those in the adults: development of atelectasis and barotrauma. During anesthesia atelectasis develop in up to 90% of patients, requiring the use of higher inspiratory pressure to recruit the collapsed lung regions. Especially in the preterm, newborn and younger infants, prolonged ventilation disturbs the anatomical structure of the soft and vulnerable immature airways and their subsequent growth and development, leading to tracheomegaly, tracheal collapse, and bronchopulmonary dysplasia and predisposing to bronchial obstruction. On the basis of pathophysiologic knowledge and studies of ventilation in children,…

Review of difficult airway management in thoracic surgery

2018

The management of difficult airway (DA) in thoracic surgery is more difficult due to the need for lung separation or isolation and frequent presence of associated upper and lower airway problems. We performed an article review analysing 818 papers published with clinical evidence indexed in Pubmed that allowed us to develop an algorithm. The best airway management in predicted DA is tracheal intubation and independent bronchial blockers guided by fibroscopy maintaining spontaneous ventilation. For unpredicted DA, the use of videolaryngoscopes is recommended initially, and adequate neuromuscular relaxation (rocuronium/sugammadex), among other maneuvers. In both cases, double lumen tubes shou…

Hemodynamic effects of dobutamine in children with cardiovascular failure.

1982

The effect of dobutamine, a synthetic catecholamine, was studied in 12 patients aged one day to 14 years with low cardiac output syndromes. After initial stabilization of the patients dobutamine was administered by continuous infusion in a dosage of 7.5 or 10 μg/kg/min. Heart rate, cardiac output (using thermodilution technique and/or pulse contour method), mean systemic and mean pulmonary artery pressures were determined before and after the dobutamine infusion. Systemic and pulmonary vascular resistances, cardiac index and stroke volume index were calculated. Cardiac output and cardiac index increased significantly in every patient, whereas the heart rate changed only slightly, suggesting…
