Introduction: The study’s objective was to validate a Malay language translated questionnaire on end-of-life care to be used among nurses practicing in critical care areas. Methods: The English language questionnaire underwent forward and backward translations by four experts. The translated Malay language questionnaire was pilot tested on 30 subjects and revised accordingly. The validation of the revised questionnaire was carried out on 250 nurses. The reliability of the translated questionnaire was checked. Cronbach alpha value of at least 0.70 suggests adequate internal consistency. The validity of the questionnaire was explored using Confirmatory Factor Analysis (CFA) and model fit tests were run to achieve fit test specific cut off values. The CFAs were run repeatedly with iterative item reductions until acceptable goodness of fit for the model was achieved. Results: All domains of the translated questionnaire showed reasonable to excellent reliability (Cronbach Alpha 0.687 to 0.922). Multiple CFAs were run and 13 out of 46 items were excluded, and the final model fit improved substantially with the indices were within the acceptable threshold of good or reasonably fit, cut off values are in brackets [Chi-Square statistics 1.635 (≤ 2.0), Root Mean Square Error of Approximation 0.050 (< 0.05), Standardised Root Mean Square Residual 0.059 (≤ 0.08), Comparative Fit Index 0.911 (0.90-0.94), Tucker Lewis Index 0.900 (0.90-0.94), Akaike Information Criteria 13024, Bayesian Information Criteria 13334]. Conclusion: The psychometric properties of the final model indicated the Malay language translated questionnaire is reliable and valid to investigate nurses’ perspective and involvement in end-of-life care.

Pharmacotherapeutics are being repurposed and used as off-label at various stages of COVID-19 infection. Clinical trials are being initiated or are ongoing to investigate the effectiveness and safety of these pharmacotherapeutics. This review article outlines the current pharmacotherapeutics and the controversies surrounding their use. The pharmacotherapeutics that were discussed are hydroxychloroquine, favipiravir, lopinavir/ritonavir, remdesivir, interferons, tocilizumab, and steroids. We also discussed the special consideration for pharmacotherapeutics in COVID-19 infection. No pharmacotherapeutics have been found to be effective and approved for the treatment of COVID-19 infection. However, there are clinical trials that have eliminated the possibilities of use of some pharmacotherapeutics while others had shown promising preliminary results of its use

Comparing the Effectiveness of Oral Celecoxib with Oral Tramadol as Pre-Emptive Analgesia in Ambulatory Surgery Nociception pathway is thought to be pre-emptively inhibited in hope to reduce acute pain in an anticipated procedural related tissue injury intraoperatively or postoperatively when pre-emptive analgesics are administered preoperatively. High intensity of pain is expected after surgical removal of the third molar which is associated with jaw swelling and limited opening of the jaw. We compare the pre-emptive analgesia effect of oral celecoxib and oral tramadol in elective ambulatory dental surgery under general anaesthesia. Informed consents were obtained from 84 patients with American Society of Anesthesiologists (ASA) physical status I or II and aged between 18 to 56 years. They were randomised to receive either oral celecoxib 200 mg (Group A) or oral tramadol 50 mg (Group B) one hour before induction of anaesthesia. Intraoperative and postoperative fentanyl consumption were compared. Numeric Rating Scale (NRS), ranging from 1 to 10, was used to assess postoperative pain scores. Group A showed a significant reduction in fentanyl consumption intraoperatively compared to Group B (p=0.047). Both groups of patients experienced mild pain at various times assessed postoperatively ranging between 0-2 NRS scores. Comparison between the groups did not detect significant reduction in pain scores and postoperative fentanyl consumption. We concluded that neither medication was found to be effective as pre-emptive analgesia, however, intraoperative fentanyl consumption was reduced by pre-emptive administration of oral celecoxib.

Estimating Surgical Duration for Surgeries: Towards an Efficient Schedule of Operating Theatre Poor operation theatre (OT) scheduling is a common cause of case cancellation on the day of surgery. We analysed the accuracy of anaesthetists and surgeons in estimating the surgical time to complete an operation and investigated whether the estimated times was correlated with the actual surgical time. It was a prospective observational study with 369 elective cases from various surgical subspecialties which were performed within three months in a tertiary university hospital. Anaesthetists and surgeons were required to estimate the surgical time of the elective cases before the day of surgery. Their estimations were compared with the recorded actual surgical time. The primary outcome was the median time difference from the estimated surgical time. Anaesthetists accurately estimated surgical times of 82 cases (22%) and surgeons 59 cases (16%). Overall, anaesthetists overestimated the surgical time by 11 minutes of actual surgical times [interquartile range (IQR) -15 to 40 minutes]. Surgeons underestimated their surgical time by 15 minutes [IQR -60 to 20 minutes]. The median estimated surgical time difference between anaesthetists and surgeons was significantly different (p<0.0001). Among the surgical subspecialties, the longest overestimation by anaesthetists was up to 48 minutes in colorectal surgeries. The most underestimated median time difference by surgeons was 65 minutes, seen in upper gastrointestinal surgeries. A significant strong positive correlation existed between overall anaesthetists' estimated and actual surgical times (rs = 0.735, p<0.0001). At the same time, there was a weak correlation between surgeons’ overall estimation time upon booking and actual surgical times (rs = 0.492, p<0.0001). In conclusion, both the anaesthetists and surgeons were significantly inaccurate in estimating the duration of surgical procedures. Although the anaesthetists tended to overestimate it while surgeons underestimated it, their estimations correlated strongly with the actual surgical times, whereas surgeons’ estimations were weakly correlated

Introduction: Pulmonary aspiration of gastric contents is a potentially life threatening complication of general anaesthesia especially in high risk patients undergoing emergency anaesthesia. Classically,ranitidine has been used to reduce gastric pH and volume. Esomeprazole, the S-isomer of omeprazole, is a newer generation proton pump inhibitor whose effect on gastric pH and volume in emergency surgeries has not been determined. Materials and Methods: This was a prospective, randomised, double blind study to compare the effect of intravenous esomeprazole and ranitidine on gastric pH and volume in patients undergoing emergency appendicectomy. Following induction of anaesthesia, seventy patients of American Society of Anesthesiologists physical status I or II had their gastric contents aspirated via a nasogastric tube. They were then randomised to receive either intravenous esomeprazole 40 mg or intravenous ranitidine 50 mg. A second aspiration of gastric contents was done three hours later. The pH and volume of gastric contents of both aspirations were recorded. Results: Both intravenous esomeprazole and ranitidine significantly reduced the gastric fluid acidity (p=0.001) and volume (p=0.001). There were no significant differences measured between the two groups in terms of gastric fluid pH (p=0.86) and gastric fluid volume (p=0.14) after administration of study drugs. Conclusion Esomeprazole and ranitidine given intravenously were both comparable in reducing the volume and acidity of gastric secretions in patients undergoing emergency appendicectomy.
