Assessment of complications and surgical timing in post-COVID-19 thoracotomy patients: A single-center experience.

Background: This study aims to assess the complications in post-novel coronavirus disease 2019 (COVID-19) thoracotomy patients and to evaluate the time interval between infection and surgery and the effect of vaccine timing and vaccine type in these patients. Methods: Between May 2020 and January 2022, a total of 74 patients (34 males, 40 females; mean age: 54.5±13.7 years; range, 22 to 27 years) who had COVID-19 infection and underwent thoracic surgery were retrospectively analyzed. Data including demographic and clinical characteristics, the surgery type, length of intensive care unit and hospital stay, and postoperative complications were recorded. Complications were defined as respiratory, cardiac, thrombotic, and other complications. The time period between COVID-19 infection and surgery was noted. All patients were questioned regarding their vaccination status. Results: Having a symptomatic COVID-19 infection did not significantly affect the development of postoperative complications and length of intensive care unit or hospital stay. Thoracic involvement was the main factor which affected the length of intensive care unit and hospital stay during COVID-19 infection (p=0.004 and p=0.003, respectively). Conclusion: Our study results suggest that the length of hospital and intensive care unit stay is related to the time period between infection and surgery. The longer that the patient waits after COVID-19 infection, the less time that the patient stays in the hospital.

Retrospective Analysis of Factors Affecting Chronic Postoperative Pain After Thoracotomy: Single Center Experience.

Objective: Despite various pain management methods, chronic pain is still a challenging issue after thoracotomy. This retrospective study was designed to determine the possible factors affecting the development of chronic pain following open thoracotomy. Methods: The study included patients who underwent elective open thoracotomy at Ankara University Ibni Sina Hospital, between 01.01.2016 and 31.12.2020. The medical files and electronic records of the patients were scanned from the system. Patient history, analgesic methods, and surgical details were recorded. The need for and usage analgesic drugs after the surgery were also recorded. Results: A total of 229 patients who underwent thoracotomy were included in the study, and 83 (36.2%) patients had chronic pain. Duration of surgery, doses of remifentanil, fentanyl or NSAI drugs, duration or number of chest tubes (more than 4 days, or more than 2 tubes), diabetes, or PCEA usage were found as variables affecting pain. Logistic Regression, Multilayer Perceptron, Naive Bayes, AdaBoost, and Random Forest methods were used to evaluate the prediction performances. According to the model created with logistic regression, the rate of the correct classification was 90.8%. The duration of surgery, remifentanil administration, chest tube for more than 4 days, and diabetes were found to be risk factors for developing chronic pain. Fentanyl bolus, PCEA-bupivacaine, and NSAID bolus were determined as preventive factors. Conclusion: A careful analysis of risk factors should be performed for each patient to prevent chronic pain after thoracotomy, and preemptive effective analgesia methods should be performed.

Cost-Effectiveness and Budget Impact of Comprehensive Anemia Management, The First Pillar of Patient Blood Management, on the Turkish Healthcare System.

Purpose: Patient blood management (PBM) is a patient-centered, evidence-based, multidisciplinary approach aimed at optimizing hemoglobin concentration, ensuring the continuity of hemostasis and minimizing blood loss in patients undergoing surgery. The aims of this study were: (1) to explore the cost-effectiveness of comprehensive anemia management, the first pillar of PBM, in non-cardiac and cardiac surgery from the Turkish Social Security Institution's (SSI's) perspective; and (2) to explore the potential budget impact of PBM for coronary artery bypass grafting (CABG) and hip and knee arthroplasty to the SSI. Methods: Cost-effectiveness and budget impact models were developed based on the avoided postoperative adverse events following implementation of the first pillar of PBM for non-cardiac and cardiac surgical patients. The probabilities of adverse events (sepsis with and without pneumonia, renal failure, myocardial infarction and stroke) were taken from a recent meta-analysis and the costs of treating these adverse events to the SSI were estimated through expert views and the use of SSI guidelines. Results: The PBM arm dominated the control arm for both non-cardiac and cardiac surgeries in terms of cost-effectiveness in the simulated cohort of patients and was associated with improved outcomes and lower costs (1768 and 1244 avoided adverse events, and incremental cost reductions for non-cardiac and cardiac surgery of 7504 Turkish lira [TRY] and 6102 TRY, respectively). The budget impact analysis showed that PBM is a potential cost-saving option for the SSI, with savings of up to 196,937,705 TRY (€12,841,697) for hip and knee arthroplasty and 24,642,504 TRY (€1,606,861) for CABG surgery. Conclusion: PBM is a cost-effective option with a potential of cost-saving for cardiac and non-cardiac surgery in Turkey.

What About Compressing the Oesophagus with an Ultrasound Probe for a Modified Sellick Maneuver?

OBJECTIVE: Debates continue about the cricoid pressure, which has been used for many years to prevent gastric aspiration during intubation. Using ultrasound, the effects of this maneuver and alternatives like paralaryngeal pressure are revealed. The aim of this observational study was to determine the effect of paralaryngeal pressure with an ultrasound probe on the esophageal diameter in patients with different body mass indexes and neck circumferences. METHODS: After measuring the neck circumference at the level of the cricoid cartilage, the esophagus was visualized by ultrasonography. Compression was applied medially at a 45° angle toward the vertebral column by the ultrasound probe and esophageal anteroposterior outer diameters were measured. Correlations between body mass index, neck circumference, esophageal diameter, and esophageal diameter change ratio were evaluated with Pearson's r value. RESULTS: One hundred ten volunteers (52 women and 58 men) with mean age 33.7 ± 8.02 years and mean body mass index 25.6 ± 4.65 kg m-2 were recruited. The esophagus was located 78.18% partially to the left, 4.54% completely to the left, 1.81% to the right of the cricoid ring. In 15.45%, esophagus could not be displayed. The mean diameter of the esophagus was 7.6 ± 1.1 mm before pressure and 5.6 ± 0.09 mm after pressure (P < .001). There was no significant correlation between diameter change percentage and body mass index (r=-0.22; P > .05). However, weak correlation was found between diameter change percentage and neck circumference (r=-0.33; P=.016). CONCLUSIONS: Paralaryngeal pressure with an ultrasound probe has the potential to occlude the esophagus and may be effective in all patient groups.

Comparison of the C-MAC D-Blade videolaryngoscope and direct laryngoscope in pediatric patients: Randomized controlled trial.

BACKGROUND: Endotracheal intubation is a key skill for clinicians and may be challenging in some patients due to various reasons. Nowadays, various kinds of videolaryngoscopes are available and usually used as a rescue device when direct laryngoscopy failed. Pediatric airway has some differences when compared with adults and may be challenging. This study aims to compare and evaluate C Mac D-Blade and commonly used Macintosh laryngoscope in pediatric patients. METHODS: In this study, 56 pediatric patients, 5-10 years old (10-40 kgs) who had undergone elective surgery and need endotracheal intubation were included after obtaining ethical board approval and informed consent from parents. The patients were randomized into two equal groups for laryngoscopy and intubation by either with Macintosh laryngoscope or C Mac D-Blade videolaryngoscope. Glottic view, number of attempts, intubation time, any complications and hemodynamic variables were recorded. A value of p<0.05 was considered significant. RESULTS: In pediatric patients with unanticipated difficult airway, the mean intubation time was significantly shorter with C Mac D-Blade (21±9 and 41±7 seconds, respectively (p<0.001). The results of the two groups were similar concerning the remaining parameters. CONCLUSION: C Mac D-Blade videolaryngoscope shortened intubation time about twice when compared to Macintosh blade C Mac D-Blade videolaryngoscope, Videolaryngoscopes may be a good alternative for routine intubation, education and a rescue device for difficult intubation.

Does Type of Pharyngeal Packing during Sinonasal Surgery Have an Effect on PONV and Throat Pain?

OBJECTIVE: Postoperative nausea and vomiting (PONV) is a common problem that affects up to 30% of all surgical patients after general anaesthesia, which increases in sinonasal surgery due the very potent emetic effect of ingested blood that is swallowed during the procedures. Therefore, a hypo/oropharyngeal packing is commonly placed in an effort to prevent blood ingestion. The primary aim of this study was to compare the efficacy of 3 packing types in preventing PONV and to compare the results with patients who received no packing. The secondary aim was to compare the postoperative throat pain in all 4 groups. STUDY DESIGN: A prospective double-blind randomized controlled study. SETTING: A university hospital. SUBJECTS AND METHODS: After Institutional Review Board approval and informed consent, 201 adult patients scheduled for sinonasal surgery were randomized to 4 groups to have dry packing (n = 52), packing soaked with water (n = 48), packing soaked with chlorhexidine gluconate and benzydamine hydrochloride (n = 51), or no packing (n = 50). Postoperative PONV and throat pain were assessed. RESULTS: Demographic data, procedural characteristics, and PONV risk scores were similar among groups. The PONV incidences, throat pain scores, and analgesic use were comparable in all 4 groups. CONCLUSION: Despite commonly used practices, usage of different types of pharyngeal packing did not affect incidence of PONV and throat pain, nor did usage of no packing.
