Serious complications related to regional anaesthesia: Study of Greek Courts' Decisions.

BACKGROUND: Regional anaesthesia and analgesia present many advantages. Related complications are few and have been fully described. Information on regional anaesthesia malpractice is lacking in Greece. The objectives of the analysis were to highlight areas of high litigation risk and report the financial impact of claims. METHODS: Published judicial decisions of criminal, civil, administrative and disciplinary content, from 1995 to 2020, were searched in the legal information banks. The court decisions were analysed by an expert in collaboration with the lawyers of the investigation. RESULTS: A total of 26 court decisions related to complications from regional anaesthesia were found involving 10 cases, which comprised: 8 convictions, 1 referral of the case for a new expert opinion and 1 acquittal. In 6 cases the medical negligence involved complications after epidural anaesthesia and in 2 after subarachnoid anaesthesia. In 1 case there was collective liability of the anaesthesiologist and the obstetrician for negligent homicide and in 7 cases liability of the anaesthesiologist for bodily injuries. The duration of the litigation was 5-16 years. CONCLUSIONS: Analysis of court cases made it possible to identify the causes that led to complications during regional anaesthesia. Informed consent, non-traumatic technique, careful patient selection, adherence to safety rules, and early diagnosis and treatment of complications are essential to avoid permanent injury.

Medical Malpractice Among Orthopedic Surgeons in Greece: An Analysis of Court Decisions.

Introduction Medical malpractice occurs when a physician, through incorrect medical action or omission, causes the patient to suffer physical harm or loss of life. Orthopedics is a high-risk medical specialty. Orthopedic surgery encompasses a wide range of procedures, including joint replacements, fracture repairs, and spinal surgeries. While orthopedic surgeons strive to provide optimal care to their patients, medical liability claims are a reality they must face. The aim of this study is to analyze the epidemiological data of judicial decisions and cases in Greece for the Specialty of Orthopedics. Material and methods Published court decisions involving medical liabilities of orthopedic surgeons and anesthesiologists, or only orthopedic surgeons were searched, in the period between 1985 and 2021. The judicial decisions were analyzed by an experienced anesthesiologist and an orthopedic surgeon based on medical knowledge and experience. Patients' age, gender, date of operation and the causes that led to the doctors' persecution were also recorded. Results Seventy court decisions of the first, second, and third degree were found. These decisions related to 34 cases: seven convictions for manslaughter, 18 convictions for bodily harm, and nine acquittals - exempting compensation. They involved 11 men and 13 women. The claims mainly related to intraoperative and postoperative complications in 20 (83.3%) of the 24 cases. Complications in elective spinal and lower extremity surgeries represent 50% (n = 12) of cases, while postoperative complications account for 16.7% of cases (n = 4). Conclusions The present study concluded that an accumulation of experience in large orthopedic centers is needed to improve the performance of orthopedic surgeons during surgery and patient monitoring. Many legal cases are due to the mismatch between patient expectations and the limitations in medicine. Thorough preoperative control and better preoperative communication with the patient are needed, in order to improve the performance of orthopedic surgeons and prevent a significant part of the claims.

Training Requirements in Point-of-Care Ultrasonography of the Upper Airway: A Feasibility Study.

OBJECTIVES: Point-of-care ultrasonography of the upper airway can be a useful supplement to conventional pre-anesthetic clinical evaluations. However, the reliability of such examinations is highly operator-dependent and proper training in sonoanatomy and ultrasound operational skills are required. The objective of this study aims to assess the minimum training requirements for applying a predefined upper airway scanning protocol in healthy volunteers by anesthesia trainees. METHODS: Twenty-two healthy volunteer members of the Operating Room staff participated in the study. A predefined scanning protocol that included the identification of specific structures (hyoid bone, vocal cords, thyrohyoid membrane/epiglottis/pre-epiglottic space, cricothyroid membrane, and thyroid gland), as well as the performance of specific measurements (distance from the hyoid bone to skin, anterior commissure to skin, epiglottis to skin, and thyroid isthmus to skin) was taught in a single-day training course. The trainees' competence was assessed after multiple scanning repetitions performed over a week. Mixed effects regression models were applied for the trainee-instructor differences in all ultrasound measurements. RESULTS: Cricothyroid membrane visualization had the lowest success rate (88%). Trainee-instructor differences were statistically significant for hyoid bone-to-skin (P < .001) and epiglottis-to-skin distances (P = .016). Measurement of the distance from the epiglottis to the skin required more scanning repetitions to achieve minimum deviance compared with other measurements. Ten or fewer scanning repetitions were sufficient to achieve minimum deviance for all four measurements. CONCLUSIONS: At least 10 scanning repetitions of a pre-defined upper airway scanning protocol can be used as the minimum standard for training.

Impact of Lower Tidal Volumes During One-Lung Ventilation: A 2022 Update of the Meta-analysis of Randomized Controlled Trials.

OBJECTIVES: To clarify the influence of lower tidal volume (4-7 mL/kg) compared with higher tidal volume (8-15 mL/kg) during one-lung ventilation (OLV) on gas exchange and postoperative clinical outcome. DESIGN: Meta-analysis of randomized trials. SETTING: Thoracic surgery. PARTICIPANTS: Patients receiving OLV. INTERVENTIONS: Lower tidal volume during OLV. MEASUREMENTS AND MAIN RESULTS: Primary outcome was PaO2-to-the oxygen fraction (PaO2/FIO2) ratio at the end of the surgery, after the reinstitution of two-lung ventilation. Secondary endpoints included perioperative changes in PaO2/FIO2 ratio and carbon dioxide (PaCO2) tension, airway pressure, the incidence of postoperative pulmonary complications, arrhythmia, and length of hospital stay. Seventeen randomized controlled trials (1,463 patients) were selected. Overall analysis showed that the use of low tidal volume during OLV was associated with a significantly higher PaO2/FIO2 ratio 15 minutes after the start of OLV and at the end of surgery (mean difference 33.7 mmHg [p = 0.02] and mean difference 18.59 mmHg [p < 0.001], respectively). The low tidal volume also was associated with higher PaCO2 values 15 minutes and 60 minutes after the start of OLV and with lower airway pressure, which was maintained during two-lung ventilation after surgery. Moreover, the application of lower tidal volume was associated with fewer postoperative pulmonary complications (odds ratio 0.50; p < 0.001) and arrhythmias (odds ratio 0.58; p = 0.009), with no difference in length of hospital stay. CONCLUSIONS: The use of lower tidal volume, a component of protective OLV, increases the PaO2/FIO2 ratio, reduces the incidence of postoperative pulmonary complications, and should be considered strongly in daily practice.

Intraoperative mydriasis in left ventricular assist device patients. Do eyes never lie?

We report two cases of transient intraoperative mydriasis in left ventricular assist device (LVAD) patients with no profound underlining neurological pathology. Both cases concern females on LVAD for more than 30 months, due to dilated cardiomyopathy, as a bridge to transplant. A possible pathophysiology mechanism is suggested. As LVAD patients' life expectancy increases, more and more physiological alterations due to laminar flow will be revealed and must be taken into consideration for the better care of this patient group.

Low-Profile Altura Endograft System for Endovascular Abdominal Aorta Aneurysm Repair. Preliminary Results in Elective and Emergent Situations.

BACKGROUND: The objective of this study was to assess the Altura endoprosthesis outcomes up to 12 months for patients affected by infrarenal abdominal aortic aneurysms (AAA) either in elective or emergent situations. METHODS: This was a single-center retrospective study identifying all patients undergoing endovascular aneurysm repair (EVAR) with the Altura endoprosthesis from January 2021 to August 2022. Outcomes evaluated included mortality, technical and clinical success (freedom from procedure-related death, endoleak, migration, thrombosis, and reintervention), and the freedom from reintervention rate. RESULTS: A total of 34 (25 elective and 8 emergent) patients who underwent AAA with Altura endoprosthesis were retrospectively reviewed. The technical success of the Altura endograft either in elective or emergent situations was 100%. There was no inhospital mortality, but 1 (3%) patient who underwent AAA repair emergently, died unexpectedly 7 days after the discharge due to massive pulmonary embolism. The clinical success and the freedom from reintervention during the median follow-up of 12 months (interquartile range [IQR] 12-18), were 97%. One patient presented with disabling intermittent claudication at third month postoperatively, and the computed tomographic angiography (CTA) revealed thrombosis of one of the iliac endografts (3%). The patient underwent femorofemoral bypass with an uneventful postoperative course and immediate relief of the symptoms. One type II endoleak was spontaneously resolved on the sixth month. Sac shrinkage (>3 mm) was registered in 12 patients (35%), but the sac size was stable in the remaining 22 (65%) patients. CONCLUSIONS: The preliminary outcomes of the Altura endograft seem to be promising, suggesting that the endograft could be safely used either in elective or emergent situations. Further studies with a major number of participants are needed to document its technical and clinical performance, especially in emergency situations that could be amenable to improvement.

Medical Liability in Obstetrics/Gynecology and Co-liability With Anesthesiology in Greece: A Retrospective Study.

Objective To evaluate the current landscape regarding medical liability in obstetric-gynecology (OB/GYN) physicians in Greece. Materials and methods Published court decisions of criminal, civil, administrative, and disciplinary content were searched in legal information banks for the years 1988-2021. The causes that led to the adverse outcome and the decisions were analyzed. Results A total of 184 decisions were directed against OB/GYNs. One hundred seventeen records concerned criminal cases and 67 civil cases. Thirty-four decisions concerned criminal cases of negligent homicide, 35 criminal cases of bodily harm, and 19 were acquittals. The most common causes of bodily injuries were neonatal encephalopathy, obstetric paralysis - quadriplegia and brachial plexus paralysis, and obstetric bleeding. Conclusion According to our results, there is a great need and challenge to maintain high standards in daily practice with continuous training and the use of international protocols. Furthermore, for each case, continuous monitoring of parturients and newborns and coordinated cooperation are necessary to reduce mortality and morbidity.

Medical Liability in Neurosurgery: Greek Courts Decisions Analysis.

AIM: The purpose of the research was to assess the current situation regarding medical liability in Neurosurgery in Greece, the involvement of Anesthesiologists in court decisions, the impact of court cases and decisions, the time until the final decision, and the relationship between these issues and judicial results. MATERIAL AND METHODS: Published court decisions of criminal, civil, administrative and disciplinary content were searched in legal information banks, from 1985 to 2021. RESULTS: A total of 52 court decisions were retrieved, 11 criminal court cases and 10 civil cases, involving 7 cases of negligent homicide and 14 bodily injuries were retrieved. The duration of litigation in 17 cases was 5.5 years, while in 4 cases the duration was 14.5 years. The average compensation paid was € 101,701. CONCLUSION: Neurosurgery has a relatively small number of reported complaints of medical negligence compared to other surgical specialties in Greece. Complications of spinal surgeries represent the majority of court cases. There is a need for immediate judicial - legislative reform of the framework for seeking medical liability of doctors.

The Effect of Cell Salvage on Bleeding and Transfusion Needs in Cardiac Surgery.

Introduction: Cell salvaging is well established in the blood management of cardiac patients, but there remain some concerns about its effects on perioperative bleeding and transfusion variables. This randomized controlled study investigated the potential effects of the centrifuged end-product on bleeding, transfusion rates, and other transfusion-related variables in adult cardiac surgery patients submitted to extracorporeal circulation. Materials and Methods: Patients were randomly chosen to receive (cell-salvage group, 99 patients) or not to receive (control group, 110 patients) the centrifuged product of a cell salvage apparatus. Bleeding and transfusion rates according to the universal definition of perioperative bleeding (UDPB) classification, postoperative hemoglobin, coagulation, and oxygenation indices were recorded and compared between the groups. Results: Both groups had almost identical bleeding and transfusion rates (median value: 2 units of red blood cells (RBC) and no units of fresh frozen plasma (FFP) and platelets (PLT) for both groups, p > 0.05). Patients in the cell-salvage group presented slightly higher hemoglobin concentrations (10.6 ± 1.1 vs. 10.1 ± 1.7 g/dL, p < 0.05, respectively) and a tendency towards better oxygenation indices (PaO2/FiO2: 241 ± 94 vs. 207 ± 84, p=0.013) in the postoperative period albeit with a tendency for prolongation of prothrombin time (INR: 1.31 ± 0.18 vs. 1.26 ± 0.12, p=0.008). Conclusion: Within the study's constraints, the perioperative use of the cell salvage concentrate does not seem to affect bleeding or transfusion variables, although it could probably ameliorate postoperative oxygenation in adult cardiac surgery patients. A tendency to promote coagulation disturbances was detected.

Globally altered sleep patterns and physical activity levels by confinement in 5056 individuals: ECLB COVID-19 international online survey.

Symptoms of psychological distress and disorder have been widely reported in people under quarantine during the COVID-19 pandemic; in addition to severe disruption of peoples' daily activity and sleep patterns. This study investigates the association between physical-activity levels and sleep patterns in quarantined individuals. An international Google online survey was launched in April 6th, 2020 for 12-weeks. Forty-one research organizations from Europe, North-Africa, Western-Asia, and the Americas promoted the survey through their networks to the general society, which was made available in 14 languages. The survey was presented in a differential format with questions related to responses "before" and "during" the confinement period. Participants responded to the Pittsburgh Sleep Quality Index (PSQI) questionnaire and the short form of the International Physical Activity Questionnaire. 5056 replies (59.4% female), from Europe (46.4%), Western-Asia (25.4%), America (14.8%) and North-Africa (13.3%) were analysed. The COVID-19 home confinement led to impaired sleep quality, as evidenced by the increase in the global PSQI score (4.37 ± 2.71 before home confinement vs. 5.32 ± 3.23 during home confinement) (p < 0.001). The frequency of individuals experiencing a good sleep decreased from 61% (n = 3063) before home confinement to 48% (n = 2405) during home confinement with highly active individuals experienced better sleep quality (p < 0.001) in both conditions. Time spent engaged in all physical-activity and the metabolic equivalent of task in each physical-activity category (i.e., vigorous, moderate, walking) decreased significantly during COVID-19 home confinement (p < 0.001). The number of hours of daily-sitting increased by ~2 hours/days during home confinement (p < 0.001). COVID-19 home confinement resulted in significantly negative alterations in sleep patterns and physical-activity levels. To maintain health during home confinement, physical-activity promotion and sleep hygiene education and support are strongly warranted.

Clinical Validation of the Greek Version of the Acute Cystitis Symptom Score (ACSS)-Part II.

The Acute Cystitis Symptom Score (ACSS) is a patient self-reporting questionnaire for the clinical diagnosis and patient-reported outcome (PRO) in women with acute uncomplicated cystitis (AC). The aim of the current study (part II) is the clinical validation of the Greek ACSS questionnaire. After linguistic validation according to internationally accepted guidelines and cognitive assessment (part I), the clinical validation was performed by using the Greek ACSS study version in 92 evaluable female participants including 53 patients with symptoms suspicious of AC and 39 controls. The clinical outcome using the ACSS questionnaire at different points in time after the start of treatment was demonstrated as well. The age (mean ± SD) of the 53 patients (44.7 ± 17.0 years) and 39 controls (49.3 ± 15.9 years) and their additional conditions at baseline visits, such as menstruation, premenstrual syndrome, pregnancy, menopause, diabetes mellitus, were comparable. There was, however, a significant difference (p < 0.001) between patients and controls at baseline visit regarding sum score of the ACSS domains, such as typical symptoms and quality of life. The clinical outcome of up to 7 days showed a fast reduction of the symptom scores and improvement of quality of life. The optimal thresholds for the patient-reported outcome of successful therapy could be established. The linguistically and clinically validated Greek ACSS questionnaire can now be used for clinical or epidemiological studies and also for patients' self-diagnosis of AC and as a PRO measure tool.

One, No One and One Hundred Thousand: Patterns of chronic prostatic inflammation and infection.

Chronic prostatic inflammation may be classified into three types that share similar symptoms and are distinguished on the basis of microbiological findings. In the present study, consecutive cases of chronic prostatic inflammation and infection were retrospectively reviewed in order to explore the clinical course and long-term outcomes. The cohort consisted of patients with symptoms of prostatitis who visited the Urology Clinic of the Tzaneion Hospital (Piraeus, Greece) between March 2009 and March 2019. The patients were subjected to the Meares and Stamey '4-glass' test and patients with febrile prostatitis were evaluated with a single mid-stream 'clean' urine sample culture. Bacterial identification was performed using the Vitek 2 Compact system and the sensitivity test with the disc and the Vitek 2 system. A total of 656 patients with prostatitis-like symptoms with 1,783 visits for investigation and follow-up were reviewed and patients were divided into two major groups. Group 1 consisted of 549 cases with a single set of chronic prostatitis (CP)-like symptoms assessed in up to three visits. National Institutes of Health (NIH) category II CP (NIH-II) was most frequently diagnosed in those patients (37,6%). At the follow-up, 125 patients were identified as having a type of CP different from that determined initially. Group 2 (107 cases) had recurring episodes of prostatitis-like symptoms assessed or confirmed over the course of 4-18 visits. Most patients (54.2%) were initially diagnosed with NIH-II followed by disease-free periods and recurrence/reinfection or by shifts to NHI-IIIB. In conclusion, CP remains a poorly understood n medical condition characterized by a variety of clinical manifestations and by transitions between different CP classes during its course.

Medico-Legal Analysis of General Surgery Cases in Greece: A 48 Year Study.

Introduction Surgery can be dangerous not only for patients, but it also carries a risk for the surgeon in case of medical error, which can affect their future medical career. The purpose of our research is to assess the current situation regarding medical liability in General Surgery in Greece, the reasons for the allegations of medical malpractice as well as the relationship between these issues and the court results. Methods Published court decisions of criminal, civil, administrative and disciplinary content were searched in legal information banks, between year 1973 and 2020. Court decisions were analyzed by an expert, a specialist general surgeon and an anesthesiologist, for the causes of death and the correctness of the court decision in collaboration with the lawyers of the investigation. Results  588 court decisions were retrieved, out if which 103 (17.751%) criminal (n = 81), or civil and administrative decisions (n ​​= 22) for surgeons. Out of a total of 81 first and second instance criminal cases and appellate court decisions of the Supreme Court, 27 cases concerned negligent homicide, 16 cases concerned negligent bodily harm and seven were acquittals. Out of 22 civil cases decisions, awarding or not awarding compensation, three cases concerned negligent homicide, seven bodily harm and two were acquittals. 11 cases of negligent homicide concerned laparoscopic and bariatric surgical procedures. Conclusions Laparoscopic surgery represents one of the most important surgical developments in the last 30 years. However, they represent a great proportion of the cases concerning medical malpractice in the greek legal system. It is important to have a national center for reporting misdiagnosis and complications and a medical liability system that will facilitate improved diagnosis, learning from diagnostic errors and delays in diagnosis, in order to avoid similar cases of malpractice in the future.

The Effect of Sugammadex on Prothrombin and Activated Partial Thromboplastin Time.

Sugammadex is routinely used as an effective neuromuscular blockade reversal agent. Several studies have indicated that it may prolong the prothrombin time (PT) and the activated partial thromboplastin time (aPTT). This review gathers the relevant in vivo studies to accumulate knowledge on the subject. Nine studies were included. According to the results, sugammadex seems to lead to a transient increase in aPTT and PT values, compared to standard care. However, the clinical impact seems to be trivial. Nevertheless, the trials' findings reveal great heterogeneity, preventing a meta-analysis. Therefore, more well-designed studies are needed to lead to prudent conclusions.
