Atelectasis is derived from the Greek words ateles and ektasis, meaning incomplete expansion. It is also referred to as collapse of the lung. Atelectasis is the loss of lung volume, either a part or all of a lung with or without mediastinal shift.
Technological advancements in imaging and intervention have allowed many disease processes to be treated outside of the operating room (OR). These advancements have provided alternative treatments to patients who are considered too high a risk or too unstable for traditional surgical procedures. As a result, there has been considerable increase in use of various levels of procedural sedation, i…
Appropriate supervision has been shown to reduce medical errors in anesthesiology residents and other trainees across various specialties. Nonetheless, supervision of pediatric anesthesiology fellows has yet to be evaluated. The main objective of this survey investigation was to evaluate supervision of pediatric anesthesiology fellows in the United States. We hypothesized that there was an in…
Procedural sedation and analgesia (PSA) has become a widespread practice given the increasing demand to relieve anxiety, discomfort and pain during invasive diagnostic and therapeutic procedures. The role of, and credentialing required by, anaesthesiologists and practitioners performing PSA has been debated for years in different guidelines. For this reason, the European Society of Anaesthesiol…
Surgery is an important component of treatment in cancer patients. However, surgical stress, anesthesia, and perioperative analgesia interfere with the host immune defense mechanisms and may contribute to metastatic dissemination of malignant tumors and cancer progression. Little is known about the effects of anesthesia on tumor recurrence. In vivo studies and clinical data show some evidence t…
A scalp block is a good perioperative and postoperative anesthesia/rnanalgesia method that has become widespread and preferred by many anesthesiologists.rnMaterial and Method: The present report presented sevenrnpatients, who underwent scalp block due to the evacuation of a subduralrnhematoma. The demographic features of the patients, sedative agents administered,rnand local anesthetic agents a…
A variety of related impurities, including starting materials, process impurities, and degradation products, can be detected in propofol. In this article, a sensitive and selective GC-MS/MS method using pulsed splitless injection technique for the determination of 11 main related impurities in propofol in one chromatogram is investigated. This method is extensively validated for its linearity, …
Nitrous oxide (N2O) has been suggested to contribute to bowel distension, resulting in worsened operating conditions for laparoscopic surgery, and to increase incidence of postoperative nausea and vomiting. Therefore, our objective was to assess the feasibility of two remifentanil-based anaesthetic regimens free from N2O with special regard to recovery profile, postoperative analgesic demand an…
Because free propofol is thought to be responsible for pain on injection, we investigated the changes in concentrations of free propofol by modifying two kinds of propofol products in a medium- and long-chain triglyceride (MCT/LCT) emulsion and in an LCT emulsion. The techniques used in this study were 1) mixing 2% lidocaine (10:1), 2) mixing 5% dextrose in acetated Ringer’s solution to r…
Pain on injection limits the use of propofol in children. The combination of lidocaine and propofol is widely used to reduce pain. A new solvent [medium-chain triglyceride (mct)/long-chain triglyceride (lct)] has been advocated to be less painful than standard (lct) propofol in adults, but no information is available of its usefulness in pre-school children. We designed a prospective, randomiz…
