Filter by:The aim of the study was to compare the efficacy and safety of single injection peribulbar anaesthesia against the classic double injection technique. This was a double blind randomized controlled trial involving two groups of consenting, adult Nigerian subjects with operable age-related cataract. An anaesthetic nurse who allocated the subjects to the two groups administered all the injections. The same surgeon operated on all the subjects while the principal investigator and a research assistant measured the outcome variables. All others were blinded as to subject allocation.
Endotracheal Tube (ETT) is still preferred for laparoscopic surgeries because of the fear of pulmonary aspiration and inadequate ventilation. Laryngeal mask Supreme (LM-S) is a single use device and the presence of a drain tube allows to separate the gastrointestinal and respiratory tracts. We planned to compare ventilation parameters and gastric distension scores of with LM-S vs ETT during laparoscopic gynecological surgery.
This study evaluates three different neuromuscular monitoring devices (acceleromyography, one- or three-dimensional, and electromyography) with regard to their precision to detect residual paralysis after injection of neuromuscular blocking agents and recurrence of paralysis after administration of reversal agents in a clinical setting.
Laryngeal mask (LM) use in gynecological laparoscopy, contrary to widespread opinion, does not increase the incidence of gastric aspiration, the failure of ventilation or the risk of pulmonary aspiration . LM is presented as an alternative to endo tracheal tube (ETT) in spontaneous or positive pressure ventilation (PPV) . LM has gained widespread popularity in England for gynecological laparoscopic procedures. In addition in many previous studies LM has been successfully shown to provide appropriate lung ventilation in laparoscopic surgical interventions .Miller et al. compared the use of ETT, LM-P laparoscopic gynecological interventions and identified advantages to LM use. The most important of these advantages was that, contrary to tracheal tube techniques for laparoscopic surgeries, use of supraglottic laryngeal devices or neuromuscular blocker agents (NBA) were not required during placement. Thus for laparoscopic surgeries, compared with the ETT technique, without the need for supraglottic laryngeal devices or muscular relaxants, it is easily placed and reduces the time spent in the operating room. Our aim; to compare the use of LM-S and ETT without neuromuscular agents for laparoscopic gynecological intervention with positive pressure ventilation from a surgical viewpoint and in terms of effect on ventilation parameters. Secondary aim, comparison of airway morbidity with endotracheal intubation and supraglottic.
To determine whether central sensitization is a mechanism of CPSP (chronic postsurgical pain) in women who will develop CPSP compared to women with no CPSP after hysterectomy. This mechanism is illustrated by a higher pain score in experimental pain models such as tonic heat stimulation, increased evoked mechanical temporal summation and increased wound hyperalgesia.
The aim of this study is to compare the combined ultrasound-guided supraclavicular brachial plexus block and distal median, radial, and ulnar nerve blocks, with supraclavicular block alone. Sixty two patients undergoing upper extremity surgery will be randomized to supraclavicular only (Group S, n=31) or supraclavicular + distal (Group SD, n=31) group. Patients in group S will receive 32 mL of lidocaine 1.5% + epinephrine 5µg/mL and in group SD receive 20 mL of lidocaine 1.5% + epinephrine 5µg/mL followed by a distal median, radial, and ulnar nerve blocks using 50:50 mixture of lidocaine 2% + levobupivacaine 0.5% (4 mL/nerve). Sensory and motor block of the ulnar, median, radial and musculocutaneous nerves will be assessed every 5 minutes starting at the 10th minutes. The imaging, needling and performance times will be recorded. Also the onset and anesthesia related times, need for analgesic and first analgesic time will be noted.
During general anaesthesia, to ensure sufficient oxygen supply to the brain, the NIRS technology can be used. It consist of two sensors placed on the forehead, and measures the oxygen saturation of the tissue underneath the sensor. For patients undergoing back surgery placed in the prone position, the NIRS measurement will be affected, because the weight of the head will produce a pressure on the sensors. We wish to investigate how much the measurement is affected. Furthermore we plan to lift the head to remove the pressure, and record the time needed for the measurements to return to baseline.
The aims of the APRICOT study are: - To establish the incidence of severe critical events in children undergoing anesthesia in Europe. - To describe the differences in paediatric anaesthesia practice throughout Europe. - To study the potential impact of this variability on the occurrence of severe critical events (Laryngospasm, Bronchospasm, Pulmonary aspiration, Drug error, Anaphylaxis, Cardiovascular instability, Neurological damage, Perianaesthetic cardiac arrest and postanaesthetic Stridor).
International multicenter observational study of a random-sample cohort of patients undergoing any in-hospital surgical procedure under general or regional anaesthesia during a continued 14-day period of recruitment. Primary hypothesis of this study is that the use of muscle relaxants, their reversal agents, or neuromuscular monitoring increases the incidence of postoperative pulmonary complications. The secondary hypothesis is that the use of muscle relaxants increases in-hospital mortality.
The purpose of this study is to determine whether continuouse positive airway pressure (CPAP), during induction of anaesthesia in morbidly obese patients, result in higher levels of oxygen in the blood.
