Context:Real-time ultrasound guidance for internal jugular (IJ) vein cannulation enhances safety and success.Aims:This study aims to compare the long- and short-axis (LA and SA) approaches for ultrasound-guided IJ vein cannulation.Subjects and Methods:Patients undergoing surgery and in intensive care unit requiring central venous cannulation were randomized to undergo either LA or SA ultrasound-guided cannulation of the IJ vein by a skilled anesthesiologist. First pass success, the number of needle passes, time required for insertion of guidewire, and complications were documented for each procedure.Results:The IJ vein was successfully cannulated in all patients. There are no significant differences between the two groups in terms of gender, diameter of IJ vein, margin of safety, and time required for insertion of guidewire. There was also no significant difference between the two groups in terms of side of IJ vein cannulated, patient on mechanical ventilation, number of skin puncture, number of needle redirections, first pass success, and carotid puncture. However, there is a significant relationship between the diameter of IJ vein with first pass (18.18 ± 4.72 vs. 15.21 ± 4.24; P < 0.004) and margin of safety with of incidence of carotid puncture (12.15 ± 4.03 vs. 6.59 ± 3.13; P < 0.016).Conclusions:Both techniques have similar outcomes when used for IJ vein cannulation.

Background: The purpose of this study was to determine the optimal pillow height for the best laryngoscopic view in adult patients scheduled for elective surgery under general anaesthesia.Methods: 150 adult patients undergoing surgery under general anaesthesia with endotracheal intubation with no features suggestive of difficult airway were enrolled for the study. After induction of anaesthesia the assessment of direct laryngoscopic views was done at head positions without a pillow and with non-compressible pillows of heights 5cm and 10cm.Results: The laryngoscopic view with the 5cm pillow was significantly superior to other head position (p<0.01). The incidence of difficult laryngoscopy (Cormack and Lehane grade III) was 32.7% without a pillow which improved to (Cormack and Lehane grade III) 4% with 10cm pillow and there were no cases of difficult laryngoscopy with 5cm pillow.Conclusions: The use of 5cm pillow in the ‘sniffing’ position obtains the best laryngoscopic view during direct laryngoscopy.Keywords: Direct laryngoscopy; head elevation; laryngoscopicview; pillow height.

Background and Aims: Use of point-of-care ultrasound (POCUS) in acute care setting has rapidly increased and has potentials to guide patient management. This survey study aims to explore the usefulness of a one-day workshop and to elicit the perceived barriers for effective use of POCUS. Methods: A total of 169 doctors who had attended one day Acute Care Ultrasound workshop were approached through email. Online link to access the survey created using Google forms was sent. The survey contained questions related to the details about the participants, feedback about the workshop, whether the workshop has helped to change the practice of the participants, availability of ultrasound machine during the daily practice and the perceived barriers for use of POCUS. Results: A total of 41 responses were obtained. Majority of the participants had anaesthesiology as the base specialty followed by general practice. Most of them had ICU as their predominant working place, followed by emergency room and operating room. The workshop was found to be helpful by most of the participants. Majority of the participants (20 participants; 49%) had ultrasound machine sometimes available during their daily practice. Only 20% (8 participants) had ultrasound machine always available during their clinical practice. Similarly, 46% (19 participants) considered lack of access to ultrasound machine as a barrier for application of POCUS. Significant number of participants considered lack of supervision and guidance (18 participants; 44%) and lack of knowledge and skills (13 participants; 32%) as the barriers. Conclusions: Majority of the participants found the one-day workshop helpful. Doctors from various specialty, working in acute care setting had participated in the survey. Limited access to ultrasound machine, together with lack of adequate knowledge and skills were perceived as major barriers for effective use of point-of-care ultrasound.

Background: Sepsis has been one of the most important conditions for morbidity and mortality of Intensive care unit (ICU) patients. Antibiotics remain one of the major combating factors for it. Indiscriminate antimicrobial usage and poor prescription practices have contributed to the development of multidrug resistant (MDR) organisms. Therefore, the current study was designed to evaluate the spectrum, and susceptibility patterns of pathogens isolated from patients admitted to our Cardiothoracic and Vascular Intensive care unit. Materials and Methods: The study was conducted in Cardiothoracic and Vascular ICU of a tertiary care teaching hospital from February 2019 to March 2021. Samples (blood, urine, wound swab, tracheal aspirate, and central venous catheter tip) for culture were taken from all the patients in Sepsis admitted in Cardiothoracic and Vascular ICU above 18 years of age during the study period. The culture reports (microbiological profile and their susceptibility pattern) were collected and data collection of all enrolled patients was done. Results: Out of the total 128 samples studied 75 (58.5%) were culture positive. The predominant organisms isolated were Gram negative organisms (Klebsiella, Pseudomonas, Acinetobacter, followed by E. coli). The highest prevalence of microbial growth was found in tracheal aspirate (46.8%), followed by blood (21.8%). Antibiotic susceptibility results showed the highest sensitivity of those common pathogens towards higher antibiotics only (especially Polymyxin B and Colistin). Conclusion: The emergence of

Introduction European System for Cardiac Operative Risk Evaluation (EuroSCORE) is the standard tool for risk stratification of patients undergoing cardiac surgery. Its relevance has been validated in European, Asian countries and also in Nepal. Its limitations led to development of EuroSCORE II. This study was carried out to compare EuroSCORE II with EuroSCORE in Nepalese cardiac surgical patients. MethodsA retrospective analytical cohort study of 3 years duration in 972 adult cardiac surgeries was conducted. Scores obtained from EuroSCORE (Logistic and Additive) and EuroSCORE II was compared with the observed mortality. Calibration was calculated by Hosmer- Lemeshow (H-L) test (Chi Square test) and discrimination by calculating the area under the curve (AUC) of receiver operating characteristics (ROC) curve. ResultsObserved mortality was 4.11%. EuroSCORE additive, logistic and EuroSCORE II predicted mortality were 4.32%, 4.55% and 2.13% respectively. H-L chi square calculation for EuroSCORE additive model could not hold as all observed and expected frequencies match exactly. Hence it can be considered as a good fit. EuroSCORE logistic model (H-L, Chi-square 7.743, p<0.001) and EuroSCORE II (H-L, Chi-square 11.631, p = 0.168) also showed good fit i.e. both can predict mortality satisfactorily. AUC of ROC curve of EuroSCORE additive, logistic and EuroSCORE II were 0.632, 0.636 and 0.616 respectively, which showed fair discrimination power. ConclusionMortality prediction of adult cardiac surgical patients by EuroSCORE (additive and logistic) and EuroSCORE II was satisfactory.
