Objective: Intraoperative hypothermia is commonly encountered in anesthetic practice. It is related to several risk factors and can lead to various adverse events. It is important to detect it early and prevent the complications related to it. This study was done to identify incidence and perioperative risk factors of intraoperative hypothermia at a national referral hospital in Bhutan.Material and Methods: A prospective observational study was conducted in adult patients who underwent elective surgery lasting more than 30 minutes. Patient characteristics, incidence of hypothermia, and any interventions for treatment of hypothermia during the operation were recorded. Intraoperative hypothermia was defined as a core body temperature less than 36 °C measured with an esophageal probe.Results: Data were obtained from 91 patients with a mean (±standard deviation; S.D.) age of 42.3 (17.2) and American Society of Anesthesiologists (ASA) scores of 1 and 2 in 62.6% and 37.4% of the patients, respectively The patients underwent elective surgery with a mean (S.D.) duration of 73.24 (48.1) minutes and a mean (S.D.) duration of anaesthesia of 80.9 (49.2) minutes. The incidence of intraoperative hypothermia was 61.5% (56/91). Preoperative heart rate more than 80 beats per minute [hazard ratio (HR) 0.45, 95% confidence interval (CI), 0.26-0.77] was a protective factor and duration of anesthesia more than 60 minutes (HR 1.82, 95% CI, 0.98–3.38) was a risk factor for intraoperative hypothermia.Conclusion: Patients with a preoperative heart rate less than 80 beats per minute and undergoing duration of anesthesia more than 60 minutes should be assessed from the preoperative period and continuously monitored throughout the intraoperative period.

Background:In the idividuals with genetic and enviromental risk factors, immune events at mucosal surfaces occur and may precede systemic autoimmunity. Anti-citrullinated protein antibodies (ACPA) are present in the serum for an average of 3-5 years prior to the onset of rheumatoid arthritis (RA) during an asymptomatic period. In ACPA-positivite individuals, the additional presence of RA-related risk factors appears to add significant power for the development of RA. To date, there have been few reports in which clinical courses of ACPA-positive asymptomatic individuals were investigated prospectively.Objectives:To observe the clinical time course of ACPA-positive healthy population for the development of RA.Methods:Healthy volunteers without joint pain or stiffness, who attended the comprehensive health screening of our hospital, were enrolled in this prospective observational study. The serum ACPA levels were quantified by Ig-G anti-cyclic citrullinated peptide enzyme-linked immunosorbent assay with levels > 4.4 U/mL considered positive. ACPA-positive subjects were followed by rheumatologists of our department clinically or a questionnaire sent by mail for screening to detect arthritis.Results:5,971 healthy individuals without joint symptons were included. Ninty-two (1.5%) were positive for ACPA. Of these, 19 (20.7%) developed RA and two were suspected as RA by mail questionnaire. Their average age were 58-years, and women were 68%. The average duration between the date of serum sampling and diagnosis was 10.7 months. ACPA-positive individuals who developed to RA had higher serum ACPA and Ig-M rheumatoid factor levels than ACPA-positive individuals who did not (P value by Mann-Whitney U test: 0.002, 0.005, respectively).Conclusion:Among ACPA-positive asymptomatic individuals, 20% developed RA. The higher titer of ACPA and Ig-M rheumatoid factor levels are risk factors for devoloping RA.Disclosure of Interests:None declared

This prospective observational study was designed to assess the incidence of, risk factors for, and outcome of catheter-related bloodstream infection in children undergoing cardiac surgery. A staff specifically trained to handle the central venous catheters with proper aseptic techniques and an appropriate patient to medical staff ratio remain the most effective measures to prevent this infection.
