    Neodymium (NdFeB) magnets have become widely available in recent years and have replaced other types of magnet in many applications in modern products that require strong permanent magnets, such as motors in cordless tools, hard disk drives and magnetic fasteners. These magnets can be used to invent a new method of energy generation by using the magnetic field of magnet and convert the magnetic energy into kinetic energy without using any kind of fuel and overcoming the energy generation problem such as building a magnetic turbine. The main objective of the study was to study about the advantage of using NdFeB magnets over other magnets, nature of different type of neodymium magnets and how it can be used to convert magnetic energy into kinetic energy

    Analgesic efficacy of the inferior alveolar nerve block for maxillofacial cancer surgery under general anaesthesia – A randomised controlled study

    Background and Aims: Mandibular resection during maxillofacial cancer surgery evokes a strong sympathetic response requiring high doses of opioids. We studied the effect of the inferior alveolar nerve block (IANB) for analgesia in maxillofacial cancer surgeries. Methods: This randomised controlled study was conducted over five months in a tertiary care cancer hospital following Institutional Ethics approval and trial registration. Fifty consenting adult patients belonging to the American Society of Anesthesiologists (ASA) physical status I and II requiring maxillofacial cancer surgery with unilateral mandibular resection were recruited. Twenty-five patients in the study arm received ipsilateral IANB; a mock injection was given to the control group. Fentanyl requirement and haemodynamic parameters during primary tumour excision were the primary and secondary endpoints. Student's t-test was applied to compare primary and secondary endpoints. Results: Forty-nine patients completed the study. Both arms were comparable with respect to age, gender distribution, ASA physical status and baseline heart rate (HR) and blood pressure (BP). The mean (standard deviation) intravenous fentanyl requirement during primary tumour excision in the IANB arm was 70(32) ÎĽg, significantly lower than 183(48) ÎĽg in the control arm, P < 0.001. The mean maximum HR during primary tumour excision was 82 and 99 per minute in the IANB and control arms, respectively (P < 0.001) whereas the maximum mean BP was 88 and 101 mm Hg, respectively (P < 0.001). Conclusion: IANB significantly reduced intraoperative fentanyl requirement and caused fewer haemodynamic changes during maxillofacial cancer surgery requiring unilateral mandibular excision

    Importance: Tracheal intubation is one of the most commonly performed and high-risk interventions in critically ill patients. Limited information is available on adverse peri-intubation events. Objective: To evaluate the incidence and nature of adverse peri-intubation events and to assess current practice of intubation in critically ill patients. Design, Setting, and Participants: The International Observational Study to Understand the Impact and Best Practices of Airway Management in Critically Ill Patients (INTUBE) study was an international, multicenter, prospective cohort study involving consecutive critically ill patients undergoing tracheal intubation in the intensive care units (ICUs), emergency departments, and wards, from October 1, 2018, to July 31, 2019 (August 28, 2019, was the final follow-up) in a convenience sample of 197 sites from 29 countries across 5 continents. Exposures: Tracheal intubation. Main Outcomes and Measures: The primary outcome was the incidence of major adverse peri-intubation events defined as at least 1 of the following events occurring within 30 minutes from the start of the intubation procedure: cardiovascular instability (either: systolic pressure &lt;65 mm Hg at least once, &lt;90 mm Hg for &gt;30 minutes, new or increase need of vasopressors or fluid bolus &gt;15 mL/kg), severe hypoxemia (peripheral oxygen saturation &lt;80%) or cardiac arrest. The secondary outcomes included intensive care unit mortality. Results: Of 3659 patients screened, 2964 (median age, 63 years; interquartile range [IQR], 49-74 years; 62.6% men) from 197 sites across 5 continents were included. The main reason for intubation was respiratory failure in 52.3% of patients, followed by neurological impairment in 30.5%, and cardiovascular instability in 9.4%. Primary outcome data were available for all patients. Among the study patients, 45.2% experienced at least 1 major adverse peri-intubation event. The predominant event was cardiovascular instability, observed in 42.6% of all patients undergoing emergency intubation, followed by severe hypoxemia (9.3%) and cardiac arrest (3.1%). Overall ICU mortality was 32.8%. Conclusions and Relevance: In this observational study of intubation practices in critically ill patients from a convenience sample of 197 sites across 29 countries, major adverse peri-intubation events - in particular cardiovascular instability - were observed frequently
