ABSTRACT
Introduction: As measured by a right heart catheterization, pulmonary hypertension is an increase in mean pulmonary arterial pressure of more than 25 mmHg at rest or more than 30 mmHg during exercise. Some of the cardiac heart conditions that may develop during pregnancy include severe mitral regurgitation and mild tricuspid regurgitation. Prior to delivery, pregnant patients with pulmonary hypertension and significant multivalvular heart disease need to undergo careful preoperative, multidisciplinary assessment, and anaesthetic planning to maximize cardiac function during the peripartum period and make informed decisions about the delivery mood and anaesthetic technique. Case Presentation: A 30-year-old Para two Gravid three pregnant mother presented with chronic rheumatic heart disease, severe mitral regurgitation, moderate pulmonary hypertension, severe left atrial dilatation, mild aortic regurgitation, and mild tricuspid regurgitation scheduled for elective cesarean section. She had one previous cesarean section four years ago with an indication of fetal macrosomia. Her cardiac condition, however, was moderate mitral regurgitation, mild left atrial dilatation, mild pulmonary hypertension, and no tricuspid or aortic regurgitation. She had continuous follow-ups after diagnosis until now but has not taken any medication. Conclusion: Anaesthesia management in a patient with severe mitral regurgitation, moderate pulmonary hypertension, severe left atrial dilatation, mild aortic regurgitation, and mild tricuspid regurgitation was challenging in resource limited area. Even if spontaneous delivery is recommended for the patients with cardiac findings, a cesarean delivery will need in the area where limited access to support it. Goal-directed perioperative management with multidisciplinary involvement helps the patient to have a good outcome.
ABSTRACT
Background: Blood transfusions play a great role to improve oxygen delivery to tissues for indicated surgical patients. Preoperative ordering of blood, especially in elective surgery, is often based on the worst-case assumptions, demanding large quantities of blood or overestimating the anticipated blood loss, of which little is ultimately used. This study aimed to assess the practices of blood requisite and transfusion in surgical patients. Method: An institutional-based prospective study was conducted from September to February 2021/2022, in Debre Markos comprehensive Specialized Hospital. Socio-demographic data like age, sex, ASA status, type of anesthesia, and type of surgeries were taken preoperatively. The number of cross-matched and transfused data were collected from patient charts throughout the perioperative periods. Efficacy of blood utilization was evaluated using the following indices like cross-match to transfusion ratio (C/T ratio), transfusion probability (%T), and transfusion index (TI); a ratio of 2.5 and below, A value of 30% and above, and values of 0.5 or more respectively were considered indicative of significant blood usage and this study is registered with a research unique identifying number of researchregistry7989 and reported in line with STROCSS 2021 guideline. Result: In all procedures, among cross-matched blood units 64.1% were unutilized. Depending on the urgency of the procedures about 77.7% of cross-matched blood units were not utilized in elective patients. In emergency procedures, the majority (64.3%) of cross-matched units were transfused. The overall blood transfusion indices result was C/T ratio, %T, and TI was 2.9, 33.5%, and 0.7, respectively. The overall blood transfusion indices for elective and emergency surgery are set respectively as follows C/T ratio (4.6 vs 1.5), %T (22 vs 78.8), and TI (0.4 vs 1.9). Among elective procedures, blood utilization was significant in orthopedic surgery with the value of C/T ratio 1.3, %T 66, and TI 1.4. In the rest of the elective procedures, blood transfusion indices were not significant. Conclusion: The overall blood utilization indices in emergency surgical patients were better than in elective and preoperative grouping, screening, and hold (GSH) is sufficient for elective surgical procedures to decrease wastage of valuable supplies.
ABSTRACT
Background: The diagnosis and treatment of pulmonary embolism have multi-modal approach based on specificity, sensitivity, availability of the machine, and associated risks of imaging modalities. Aim: This review aimed to provide shreds of evidence that improve perioperative diagnosis and management of suspected pulmonary embolism. Methods: The study was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline 2020. After a clear criteria has been established an electronic searching database was conducted using PubMed, Google Scholar, Cochrane library, and Cumulative Index of Nursing and Allied Health Literature (CINAHL), with Key search terms included:('pulmonary embolism' AND' anesthesia management ', 'anticoagulation' AND 'pulmonary embolism', 'thrombolysis 'AND 'pulmonary embolism', 'surgery' AND' pulmonary embolism'), were used to draw the evidence.The quality of literatures were categorized based on WHO 2011 level of evidence and degree of recommendation, in addition, the study is registered with research registry unique identifying number (UIN) of reviewregistry1318." and has high quality based on AMSTAR2 assessment criteria. Results: A totally of 27 articles were included [guidelines (n = 3), Cochrane (=5), systemic reviews (n = 7), meta-analyses (=2), RCT (n = 4), cohort studies (n = 3), and cross-sectional study (n = 3) and illegible articles identified from searches of the electronic databases were imported into the ENDNOTE software version X7.1 and duplicates were removed. Discussion: Currently divergent and contradictory approaches are implemented in diagnosis and management for patients suspected of pulmonary embolism. Conclusion: All perioperative patients, especially trauma victims, prostate or orthopedic surgery, malignancy, immobility, and obesity; smokers; and oral contraceptive users, antipsychotic medications are at increased risk of venous thromboembolism and need special caution during surgery and anesthesia.
