Mediastinal venolymphatic malformations (VLM) are rare tumours, with very few reported cases in the literature. Arising often from the anterior mediastinum, VLM manifests symptoms based on invaded surrounding structures. Masses from the anterior and superior mediastinum pose an anaesthetic challenge for airway and hemodynamic management. A 7-month-old male child presented with a progressively growing mass over the left anterior chest wall for one month, about 4x4 cm, with diffuse margins and now expanded to involve the root of the neck and into the axilla. The patient was free from any apparent systemic illness. The breathing difficulty worsened in the past week with noisy respiration associated with feeding difficulty and hence sought medical admission to the paediatrics emergency unit. In conclusion, such huge mediastinal masses are managed better under spontaneous ventilation with an adequate surgical depth of anaesthesia to maintain appropriate respiratory compliance and necessitate lower peak inspiratory pressure. Given rare cases reported in the literature, similar topics would help choose the modus of ventilation and their safe management.

Objective: New-onset atrial fibrillation (NOAF), an important postoperative complication, has pertinent inflammatory links. Motivated by the encouraging literature on the prognostic role of hypoalbuminemia, leukocytic indices [LIs: neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio (MLR)], systemic inflammation response index (SIRI=NLR×monocyte) and platelet-leukocytic indices [PLIs: platelet-to-lymphocyte ratio (PLR)], systemic immune inflammation index (SII=NLR×platelet), aggregate index of systemic inflammation (AISI=NLR×platelet×monocyte), we sought to investigate the NOAF-predictive value of preoperative albumin-adjusted indices (aa-LIs and aa-PLIs) in an off-pump coronary artery bypass grafting (OPCABG) setting.

Methods: Of 899 patients, 151 patients (16.79%) developed the primary outcome i.e. NOAF that was analyzed further retrospectively for its predictors instead of the highlighted text perioperative data of 899 patients undergoing elective OPCABG, were retrospectively analyzed. The study participants were categorized into non-NOAF and NOAF groups (defined as new-onset atrial arrhythmia with irregular RR interval with indistinct P wave in the first week postoperatively).

Results: One hundred and fifty-one patients (16.79%) developed NOAF. On univariate analysis: age, smoker status, The European System for Cardiac Operative Risk Evaluation (EuroSCORE) II, systemic hypertension, diabetes mellitus, prior congestive heart failure (CHF), and a higher preoperative NLR, PLR, SII, and albumin were significant predictors of NOAF. While age, CHF, and EuroSCORE II retained predictive significance in multivariate analysis, LI-PLIs and albumin did not emerge as independent NOAF predictors. Notably, aa-NLR, aa-PLR, and aa-SII independently predicted NOAF on the computation of model-estimates in the regression analysis (Odds ratio; 95% confidence interval: 31.05;15.75-70.61, 1.04;1.02-1.05, 1.12;1.10-1.14, respectively, P < 0.001). aa-NLR ≥1.32, aa-PLR ≥52.64, and aa-SII ≥344.38 predicted NOAF with the respective AUC;sensitivity;specificity of 0.66;63.6%;73.3%, 0.63;66.2%;59.0%, and 0.65;58.3%;78.2%. Preoperative aa-NLR, aa-PLR and aa-SII also positively correlated with CHA₂DS₂-VASc score (R=0.40, 0.45 and 0.42; P < 0.001).

Conclusion: The independent NOAF predictive value of aa-NLR, aa-PLR, and aa-SII reiterates the inflammatory relationship of the arrhythmic complication following OPCABG.

Objective: Intrathecal morphine is used as an effective component of multimodal analgesia in postoperative analgesia in cesarean section patients. We aimed to analyze the relationship between intrathecal morphine administration and postdural puncture headache (PDPH), pain score and analgesia consumption in the postoperative period, and maternal fetal effects.

Methods: One hundred four pregnant women aged ≥18 years (American Society of Anesthesiology physical status I or II, >36 weeks gestation) who were scheduled for elective cesarean section under spinal anaesthesia were included in this study. Spinal anesthesia consisted of bupivacaine with or without morphine (Group M: 10 mg heavy marcaine + 25 mcg fentanyl + 100 mcg morphine; Group F: 10 mg heavy marcaine + 25 mcg fentanyl). The effect of intrathecal morphine on PDPH, postoperative pain score, analgesia consumption, and maternal and fetal effects were recorded for 5 days.

Results: PDPH developed in a total of 33 patients (Group M: 18 and Group F: 15, P=0.274). When we evaluated PDPH with the VAS, there was no significant difference between the groups. The postoperative visual analogue scale (VAS) was lower in the morphine group, and no statistically significant difference was found in the VAS 1^st hr and VAS 2^nd hr, whereas the VAS 6^th hr and VAS 24^th hr were found to be statistically significant. There was no difference in terms of PDPH, the first analgesic requirement and postoperative nausea-vomiting, but meperidine consumption was lower in the morphine group.

Conclusion: Low-dose intrathecal morphine did not affect the incidence of PDPH. It is an effective method that can be used in cesarean section patients without increasing the maternal and fetal side effects from postoperative analgesia.

Objective: The Coronavirus disease-2019 (COVID-19) outbreak has deprived simulation-based medical education for health care workers. Attendees are strictly prohibited to converge at a simulation training venue because of the COVID-19 outbreaks. To address this issue, we developed a web-conference-style remote simulation program using demonstration video clips. This report introduced the method and described participants' satisfaction.

Methods: This preliminary survey study evaluated learners' satisfaction in multiple institutions. The Satisfaction Scale Questionnaire with High-Fidelity Clinical Simulation (SSHF) by a 5-degree scale was used to evaluate participants' satisfaction. The survey was conducted immediately after completing the simulation sessions.

Results: Ten (100%) participants (7 anaesthesia individuals, 2 anaesthesia residents and 1 nurse anaesthetist) from nine institutions responded to the survey. All median values of the satisfaction scores were ≥4.0, whereas the median values of scores for environmental fidelity and psychological insecurity were 3.5 and 3.0, respectively (P=0.005).

Conclusion: A web-conference-style remote simulation using demonstration video clips is a feasible method for conducting simulation-based medical education under COVID-19 that showed high satisfaction scores. Further, additional studies are required to explore the internal and external validity and the effectiveness of mastery learning.

Objective: The aim of this study is to assess the factors affecting the preference for the Pain Medicine subspecialty and the fellowship training programs by the pain specialists who have completed or continued the Pain Medicine fellowship training program from 2014 to 2021 in Turkey.

Methods: The study was conducted in October 2020 and March 2021. By reaching out to the pain specialists who completed their fellowship or had been continuing their training by getting the right to receive a Pain Medicine fellowship. Via e-mail or WhatsApp application, an e-questionnaire link was sent to the participants, and data were collected on demographics, factors affecting the choice of Pain Medicine subspecialty, level of realization of the expectations during the training course and the level of proficiency in the field of pain specialization. Data analysis was performed using IBM SPSS Statistics 20.0 software, and tests were considered statistically significant if P < 0.05.

Results: Participants reported that the factors that most affected their preferences were personal interest (55.1%), more comfortable working conditions (43.6%), and interest in an academic career (38.5%). Seventy-six participants answered the level of realization of expectations about performing interventional pain procedures using ultrasound imaging, and 31.6% reported that their expectations were not met, and 25% reported that their expectations were partially realised.

Conclusion: We hope that our findings will lead to improving Pain Medicine subspecialty training programs, upgrading standards, and more comprehensive studies on these issues.

Objective: Dural puncture epidural technique is refinement of standard epidural technique. Its goal is to overcome drawbacks of standard epidural. We assessed whether dural puncture epidural technique performed by 27-gauge spinal needle would provide higher quality of labour epidural analgesia by using 10 mL epidural bolus of 0.125% bupivacaine. Additionally, the impact of dural puncture epidural on epidural analgesia onset, course of labour and occurrence of maternal side effects was examined.

Methods: We designed prospective, randomized, single-blind study. A total of 76 healthy nulliparous parturients were randomly allocated to dural puncture or standard epidural group. After identification of epidural space, spinal Whitacre needle was used for dural puncture. Intrathecal drug administration was omitted at that point. Both groups received a bolus of local anaesthetic mixture, followed by a continuous infusion of diluted local anaesthetic via epidural catheter. Pain was assessed by numeric pain rating scale. The number of top-ups and mode of delivery were recorded in both groups.

Results: After 10 minutes, there was a statistically significant difference in numeric pain rating scale ≤3 reported (P=0.028), with 97.4% subjects in dural puncture epidural group achieving adequate analgesia after 10 minutes. There was no statistically significant difference in the number of additional boluses, time to delivery, Bromage scale achieved or maternal outcomes between groups.

Conclusion: Dural puncture epidural technique appears to be effective in providing faster onset of epidural analgesia. However, the need for additional boluses remains unchanged. It can be safely used in obstetrics, without deleterious effect on the course of labour.

Objective: Red blood cell (RBC) transfusion in cardiac surgery is associated with increased morbidity and mortality. Even when using patient blood management methods, blood transfusions may still be needed in cardiac surgery. This study examined the risk factors for blood transfusion in isolated coronary artery bypass graft (CABG) surgery with a restrictive transfusion strategy, along with individualized patient blood management.

Methods: We enrolled 198 patients (age, 61.8 ± 9.9 years; 28 females and 170 males) who underwent isolated CABG surgery in a single private hospital using a restrictive transfusion strategy between April 2015 and October 2020. Pre-, intra-, and postoperative parameters were compared between patients with and without RBC transfusions. The risk factors for transfusion and transfusion probability were analyzed.

Results: Patients who received RBC transfusions had higher European System for Cardiac Operative Risk Evaluation values (13.60 ± 18.27%). Preoperative hematocrit (Hct) [odds ratio (OR)=0.752; 95% confidence interval (CI) 0.639-0.884; P=0.001] and female gender (OR=7.874; 95% CI 1.678-36.950; P=0.009) were significant independent risk factors for RBC transfusion in logistic regression analysis. When the preoperative Hct was 30%, the RBC transfusion probability was 61.08% in females and 16.6% in males. Patients who received RBC transfusions had longer intensive care unit (31.40 ± 25.42 hours) and hospital (11.18 ± 6.75 days) stays.

Conclusion: Risk factors for RBC transfusion in isolated CABG surgery with a restrictive blood transfusion strategy were preoperative anemia and female gender.
