Case ReportsAnesthetic breathing circuit obstruction mimicking severe bronchospasm: an unusual manufacturing defect.
We report an unexpected ventilation difficulty with an anesthetic breathing circuit in a pediatric patient receiving left herniorrhaphy. A manufacturing defect in a limb of the anesthetic breathing circuit caused this problem. This defect induced a high-pitched, wheezing-like sound, which was difficult to differentiate from a hyper-reactive airway, commonly seen in pediatric patients with recent upper respiratory tract infection. We recommend that the patency of the anesthetic breathing circuit should routinely be examined before connecting it to the anesthesia machine.

Direct endotracheal intubation using a novel detachable optic probe (Sunscope) by emergency medical technicians with various training backgrounds.
Effective airway management requires both proper technique and the appropriate devices. With the widespread implementation of advanced life-support techniques in emergency medical services (EMS), orotracheal intubation is now performed not only by professional practitioners but, in many occasions, nonprofessionals. With extensively diversified skill equipped, we tested whether the Sunscope, a patented tracheal intubation device with a digital display, is able to facilitate tracheal intubation by naïve EMS personnel with various training backgrounds. ⋯ Our research demonstrates that professional practitioners are able to use the Sunscope on their first attempt. Despite a lack of training in conventional endotracheal intubation, emergency medical technicians (EMT-I and -II) were able to complete intubation on their first attempt; a significant reduction in the time required to intubate was noted after repeated practice. All levels of naïve EMTs were able to readily visualize the vocal cords through Sunscope and, thereby, reliably insert the endotracheal tube in less than 1 minute, regardless of their skills before testing.

Preoperative anxiety in surgical patients - experience of a single unit.
Preoperative anxiety has a significant effect on the outcome of anesthesia and surgery. At present, there is no published data on the preoperative anxiety levels in Sri Lankan patients. In the West, several validated questionnaires such as The Amsterdam Preoperative Anxiety and Information Scale (APAIS) and State Trait Anxiety Inventory (STAI) are used. To measure the preoperative anxiety levels in patients using APAIS and to analyze the factors affecting anxiety and the role played by the anesthetist in allaying anxiety. ⋯ The prevalence of anxiety is high among Sri Lankan patients. Females are more anxious than males and those who have never had surgery are more anxious than those who have had surgery. The anesthetist's visit could reduce anxiety. Sinhala version of the APAIS is highly reliable in assessing the preoperative anxiety levels.

ReviewReview of interscalene block for postoperative analgesia after shoulder surgery in obese patients.
In recent years, the prevalence of obesity has significantly increased in developed countries, a trend that has been just as apparent in France as elsewhere. Obesity may predispose to osteoarthritis, which may subject a high percentage of patients to shoulder surgery. Interscalene block remains one of the most efficient technique for postoperative analgesia after shoulder surgery. ⋯ In obese patients undergoing shoulder surgery, the goal of postoperative pain management is to provide comfort, early mobilization, and improved respiratory function without the worry of inadequate sedation and respiratory compromise. The ongoing debate on the relevance of obesity, for example in terms of obstructive sleep apnea syndrome, obesity hypoventilation syndrome, and other related respiratory disturbances, in relation to the choice of analgesic techniques, especially interscalene block, patient-controlled intravenous analgesia and patient monitoring, demands large-scale, well-designed studies to resolve it. Nevertheless, obesity per se should not dissuade patients from undergoing shoulder surgery under interscalene block.

Case ReportsDevelopment of acute ischemic stroke in a patient with acute respiratory distress syndrome (ARDS) resulting from H1N1 pneumonia.
Pneumonia due to H1N1 infection is now very common. We report a case of ischemic stroke which arose subsequently to H1N1 influenza. The patient was a female who developed acute respiratory distress syndrome (ARDS) after H1N1 influenza, was ventilated as per standard protocol and started treatment with oseltamivir. ⋯ In the course of time, she had acceptable neurological recovery following treatment with aspirin and neuro-rehabilitation. This case report provides evidence that a rare, debilitating complication like stroke can occur in H1N1 infection. A high index of suspicion of the probability of a cerebrovascular event should be borne in mind and regular neurological assessment should be done in such cases.
