RESUMO

BACKGROUND: The anesthetic management of parturients with ascending aortic aneurysm for cesarean section can be particularly challenging, primarily because of increased risk for aortic dissection or aneurysm rupture. CASE PRESENTATION: We present some aspects of the anesthetic management of two parturients with ascending aortic aneurysm for cesarean sections; amongst, the use of remifentanil with its effects on patient and newborn. We emphasize the importance of a cardio-obstetric team in the context of preoperative planning of such patients. Also, we reviewed some literature on the anesthetic management with its effect on peri-operative hemodynamic stability. CONCLUSION: Maintaining hemodynamic stability is paramount in the prevention of the rupture or dissection of ascending aortic aneurysm during labor of parturient.

RESUMO

AIM: To assess the attitudes of nursing students toward artificial intelligence. BACKGROUND: Possible applications of artificial intelligence-powered systems in nursing cover all aspects of nursing care, from patient care to risk management. Although the final acceptance of artificial intelligence in practice will depend on positive 'nurses' attitudes toward artificial intelligence, those attitudes have gained little attention so far. DESIGN: A cross-sectional multicenter study. METHODS: The study was performed at nursing schools of four Croatian universities, surveying a total of 336 first-year nursing students (response rate 69.7%) enrolled in 2021. A validated instrument, the General Attitudes towards Artificial Intelligence Scale, consisting of 20 Likert-type items, was chosen for the study. Where applicable, the items were contextualized for nursing. Four sub-scales were identified based on the outcomes of the factor analysis. RESULTS: The average attitude score was (mean ± standard deviation) 64.5 ± 11.7, out of a maximum of 100, which was significantly higher than the neutral score of 60.0 (p < 0.001). The attitude towards AI did not differ across the universities and was not associated with students' age. Male students scored slightly higher than their female colleagues. Scores on subscales "Benefits of artificial intelligence in nursing", "Willingness to use artificial intelligence in nursing practice", and "Dangers of artificial intelligence" were favorable of artificial intelligence-based solutions. However, scores on the subscale "Practical advantages of artificial intelligence" were somewhat unfavorable. CONCLUSIONS: First-year nursing students had slightly positive attitudes towards artificial intelligence in nursing, which should make it easier for the new generations of nurses to embrace and implement artificial intelligence systems. Reservations about artificial intelligence in daily nursing practice indicate that nursing students might benefit from education focused specifically on applications of artificial intelligence in nursing.

RESUMO

Pulmonary arteriovenous malformations are abnormal, direct communications between the branches of the pulmonary artery and pulmonary veins, but without pulmonary capillaries between them. During pregnancy, PAVMs can enlarge and become symptomatic, causing even serious complications like haematothorax. To recognize the PAVM that becomes symptomatic in pregnancy, one must be able to distinguish the patient's symptoms caused by developing complications of PAVM, as in the case we present, from physiological changes accompanying a healthy pregnancy, including their degree in relation to the stage of pregnancy. The modified early obstetric warning score charts are a very helpful tool in the assessment of (ab)normal signs and symptoms in pregnant women, especially for physicians who rarely manage pregnant women.

RESUMO

During November to December 2020, a high rate of COVID-19-associated pneumonia with bacterial superinfections due to multidrug-resistant (MDR) pathogens was recorded in a COVID-19 hospital in Zagreb. This study analyzed the causative agents of bacterial superinfections among patients with serious forms of COVID-19. In total, 118 patients were hospitalized in the intensive care unit (ICU) of the COVID-19 hospital. Forty-six out of 118 patients (39%) developed serious bacterial infection (VAP or BSI or both) during their stay in ICU. The total mortality rate was 83/118 (70%). The mortality rate due to bacterial infection or a combination of ARDS with bacterial superinfection was 33% (40/118). Six patients had MDR organisms and 34 had XDR (extensively drug-resistant). The dominant species was Acinetobacter baumannii with all isolates (34) being carbapenem-resistant (CRAB) and positive for carbapenem-hydrolyzing oxacillinases (CHDL). One Escherichia coli causing pneumonia harboured the blaCTX-M-15 gene. It appears that the dominant resistance determinants of causative agents depend on the local epidemiology in the particular COVID center. Acinetobacter baumannii seems to easily spread in overcrowded ICUs. Croatia belongs to the 15 countries in the world with the highest mortality rate among COVID-19 patients, which could be in part attributable to the high prevalence of bacterial infections in local ICUs.

RESUMO

Late obstetric ethylene glycol intoxication represents a diagnostic challenge for acute care physicians and an impending life threat with life-long implications for both the mother and the fetus. The metabolism of ethylene glycol to its toxic metabolites during late pregnancy is unpredictable due to maternal physiological changes. Namely, the hallmark signs and symptoms of ethylene glycol intoxication can mimic those of late pregnancy-related high blood pressure disorders, which makes it difficult to correctly diagnose the condition. Therefore, it is crucial to promptly recognize late obstetric ethylene glycol intoxication and initiate specific treatment, but evidence-based recommendations are not available to guide its most effective emergent treatment. We present our department's emergent management of late-obstetric ethylene glycol intoxication. The parturient was stabilized by inhibiting ethylene glycol metabolism, alongside general supportive care measures. The enhancement of its toxic metabolites was eliminated by administering ethanol via the enteral route, which progressively improved the parturient's clinical course and led to the on-term delivery of a healthy child. Our case shows the importance of a meticulous emergent assessment, prompt diagnosis, and carefully planned multidisciplinary treatment in the emergency department in improving outcomes after ethylene glycol intoxication in late pregnancy.

RESUMO

Extra-adrenal myelolipomas are rare, asymptomatic entities, although large tumors may cause local symptoms or hemorrhage. When these lesions occur outside the adrenals in the retroperitoneum, they are radiographically easily confused with both primary and secondary retroperitoneal tumors, which tend to be aggressive. Although myelolipomas are benign and can be managed conservatively, if malignancy is suspected, a surgical procedure is an option. We report a case of a 68-year-old patient with multiple perirenal extra-adrenal myelolipomas. Initial abdominal ultrasound reviled an inhomogeneous mass surrounding the left kidney. Subsequent CT examination of the abdomen showed four separate, extrarenal, well-circumscribed, round-shaped, fat-containing retroperitoneal tumors. Given the significant size of the masses, that compressed major abdominal vessels and the suspicion of liposarcoma, a surgical excision of the lesions was performed. The tumors were easily separated, all surrounding structures were spared, and they were removed completely. Histologically, all masses consisted of hematopoietic and mature fat tissue and the final diagnosis was extra-adrenal myelolipoma. The patient was released from the hospital 7th day after surgery in good condition and at his baseline. Since myelolipomas are, by definition, nonfunctional benign tumors, there was no need for further follow-up. The radiological evaluation and fine needle biopsy are usually sufficient to establish the diagnosis, but in some cases of well-differentiated liposarcoma, the differentiation between myelolipoma and liposarcoma can be challenging. Therefore, considering that myelolipomas and liposarcomas have opposite prognoses, which affects the surgeon's decision on the extent of surgical procedure and further treatment, we also emphasize the importance of intraoperative assessment of the tumor, both by the surgeon and by intraoperative pathology consultation.

RESUMO

BACKGROUND: Although it was previously shown that prolonged prophylactic antibiotic exposure and multiple inadequate antibiotic therapies are independent risk factors for multidrug-resistant ventilator associated pneumonia there were no studies investigating whether pre-operative prophylactic dose of antibiotics changes oral microbiome and increases the risk of ventilator associated pneumonia. The aim of the study was to determine if pre-operative prophylactic dose of antibiotics affects the oral microbiome, increases the colonization with Gram-negative bacteria and subsequent risk of ventilator associated pneumonia. SUBJECTS AND METHODS: Mechanically ventilated adult patients receiving surgical antibiotic prophylaxis were included in the study. The presence of Gram negative microorganisms in the pre-prophylactic and post-prophylactic oral swabs and tracheal aspirates, as well as the occurrence of ventilator associated pneumonia, were analyzed. RESULTS: Number of patients colonized with Gram negative bacteria in post- prophylactic oral swab was significantly higher compared to oral swab taken before prophylactic antibiotic. On the other hand, the number of patients with Gram- negative bacteria in tracheal aspirates remained similar as in post- prophylactic oral swabs. Moreover, we found that presence of Gram- negative bacteria in both pre- and post- prophylactic oral swabs was in the positive correlation with the presence of Gram- negative bacteria in tracheal aspirates. CONCLUSIONS: This study showed increased colonization of oral cavity with Gram- negative bacteria after preoperative prophylactic antibiotics. Furthermore, receiving two prophylactic antibiotics from WHO Watch list increased the incidence of Gram- negative bacteria in oral swabs and tracheal aspirates, and the risk of ventilator associated pneumonia development.

RESUMO

The expertise to recognize and manage the difficult airway is essential in anesthesiology. Conventionally, this refers to anatomical concerns causing difficulties with facemask ventilation and/or with tracheal intubation. Severe derangements in patients' physiology can make induction and intubation likewise difficult, and approximately 30% of critically ill patients had cardiovascular collapse subsequently to intubation. We present the case of a 58-year-old male with a past medical history of type II diabetes and hypertension who presented with altered mental status due to severe metabolic acidosis with a pH of 6.8 on admission to the intensive care unit. The anesthesia team was called to urgently intubate the patient. Upon arrival, the patient was localizing to pain and was hypocapnic, tachycardic, and hypotensive despite ongoing therapy with norepinephrine, vasopressin, and bicarbonate drips. Bedside point-of-care ultrasound showed hyperdynamic left ventricle with no other abnormalities. The patient was induced with IV ketamine, and dissociation occurred with maintenance of spontaneous respirations, which was followed by laryngoscopy and intubation causing only minimal hemodynamic changes. The patient was subsequently dialyzed and treated supportively. He was discharged from the hospital two weeks later-neurologically intact and at his baseline. Combination of hypotension and severe metabolic acidosis is particularly a challenging setting for airway management and a major risk factor for adverse events, including cardiopulmonary arrest. Hemodynamically stable induction agents should be preferred. In addition, sustaining spontaneous ventilation and avoiding periods of apnea in the peri-intubation period is paramount-any buildup of CO2 could push a critically low pH even lower and cause cardiovascular collapse. Sympathomimetic properties of ketamine make this induction agent a particularly appealing choice in this setting. This case report further supports the concept that severe physiologic perturbations-in which conventional induction techniques are not feasible-should be included in the current definition of a difficult airway.

RESUMO

BACKGROUND: There are no data on the difference between the impact of ropivacaine and levobupivacaine on sympathetic nerve fibers during central neuraxial blocks. We hypothesized that there is no difference in the degree of sympathectomy between the two drugs during lumbar epidural analgesia for labor pain. METHODS: Sixty healthy parturients were randomized to the type of local anesthetic-opiod solution administered in the epidural space: 10 mL of 0.125% ropivacaine + 100 mcg of fentanyl or 10 mL of 0.125% levobupivacaine + 100 mcg of fentanyl. After the baseline measurement, photoplethysmography signal from the first toe of the leg was recorded 5, 10 and 20 minutes after administration of epidural analgesia. RESULTS: Area under the curve and the pulse transit time of the toe photoplethysmography increased in both groups during the first 20 minutes after administration of epidural analgesia (P < 0.001 for both parameters in both groups). No difference in the degree of sympathectomy was found between the groups for the area under the curve. The difference in the change of the pulse transit time suggests that the two local anesthetics might differ in the degree of sympathectomy (P = 0.024). CONCLUSION: 0.125% ropivacaine and 0.125% levobupivacaine do not differ in the terms of sympathectomy-mediated side effects of the epidural block for labor analgesia. However, the photoplethysmography findings suggest a certain difference in the degree of sympathectomy between the two local anesthetics.

RESUMO

Ischemic stroke related to tandem internal carotid and middle cerebral artery (TIM) occlusion is a challenging condition where endovascular treatment (EVT) is an emerging revascularization option. The identification of factors influencing clinical outcomes can assist in creating appropriate therapeutic algorithms for such patients. This study aimed to evaluate prognostic factors in the context of EVT for TIM occlusion. We performed a retrospective study of consecutive patients with TIM occlusion admitted within 6 h from symptom onset to two tertiary stroke centers. We recorded the etiology of stroke, clinical deficits at stroke onset and discharge, details of EVT, final infarct volume (FIV), in-hospital mortality, and outcome at three months. Among 73 patients with TIM occlusion, 53 were treated with EVT. The median age was 75.9 years (interquartile range (IQR) 64.6⁻82.6), with the most common etiology of cardioembolism (51.9%). Intravenous thrombolysis with tissue-plasminogen activator (t-PA) was performed in the majority (69.8%) of cases. EVT achieved successful recanalization with a thrombolysis in cerebral infarction (TICI) grade of 2b or 3 in 67.9%. A good outcome (modified Rankin score of 0⁻2 at three months) was observed in 37.7%. After adjustment for age, the National Institutes of Health Stroke Scale (NIHSS) at admission, and success of recanalization, smaller final infarct volume (odds ratio (OR) 0.021 for FIV above 25th percentile (95% CI 0.001⁻0.332, p = 0.005)) and administration of intravenous t-PA (OR 12.04 (95% CI 1.004⁻144.392, p = 0.049)) were associated with a good outcome at three months. Our study demonstrates that bridging with t-PA is associated with improved outcomes in the setting of tandem ICA and MCA occlusions treated with EVT and should therefore not be withheld in eligible patients.

RESUMO

A patient presented with a stab injury caused by a knife penetrating the orbital floor and maxillary sinus along the skull base with the tip situated adjacent to the left internal carotid artery. A flexible fiberoptic bronchoscope loaded with an endotracheal tube was initially positioned superior to the vocal cords and advanced into the trachea immediately following induction. The blade was removed after occluding endovascular balloons were positioned distal and proximal to the potential internal carotid artery injury site. Therefore, contralateral nasal fiberoptic intubation might be safely performed in patients with unilateral maxillofacial trauma, no intracranial penetration, and minimal bleeding.

RESUMO

BACKGROUND/OBJECTIVE: Incisional hernias (IHs) are a major problem following abdominal surgery. In an effort to resolve large IHs adequately, we herein present our own modified "open intraperitoneal mesh" technique, termed the Garestin technique. METHODS: We analyzed early postoperative complications (EPCs; wound infection, hematoma, and seroma) and late postoperative complications (recurrence) in 124 patients operated for IHs and recurrent IHs (RIHs) using our new technique. Our technique involved repairing hernias by preserving the hernia sac, which was later used to conceal the mesh that replaced the abdominal wall defect, thus dividing the mesh from subcutaneous tissue. RESULTS: We operated 66 patients with IH and 58 patients with RIH. In the 4-week postoperative follow-up, 29 patients had EPC; 9 of them had wound infections that healed upon antibiotic therapy, without the need for any surgical procedure. Of the 10 patients with recurrent herniation in the long-term follow-up, 6 previously had EPC. Recurrences occurred 4-25 months after the operation. CONCLUSION: Our method is reliable and safe for large ventral hernia disposal, but the final conclusion requires a larger number of patients and a longer follow-up period.

RESUMO

We explored whether clot density in middle cerebral artery (MCA) occlusion is related to clinical variables, stroke etiology, blood constituents, and prestroke medication. We performed a retrospective chart review of patients with acute ischemic stroke of the anterior circulation admitted to two Central European stroke centers. The acquisition of non-contrast enhanced CT (NECT) and CT angiography (CTA) within 4.5 h of symptom onset was obligatory. We assessed the site of MCA occlusion as well as density, area, and length of the clot in 150 patients. The Hounsfield unit values for the clot were divided with contralateral MCA segment to yield relative Hounsfield Unit ratio (rHU). The site of the vessel occlusion (M1 vs. M2) and antiplatelet usage, but not stroke etiology, significantly influenced rHU. We found an inverse correlation of rHU with erythrocyte count (p < 0.001). The multivariate analysis revealed that a higher rHU (i.e., clot being more hyperdense) was more likely with the use of antiplatelets (OR 4.24, CI 1.10-16.31, p = 0.036). Erythrocyte (OR 0.18, CI 0.05-0.55, p = 0.003), and thrombocyte counts (OR 0.99, CI 0.98-0.99, p = 0.029) were associated with odds for more hypodense clots (lower rHU). Our study disclosed that antiplatelet therapy impacts the composition of intracranial clots of the anterior circulation.

RESUMO

Despite decades of experience in tracheotomy, there still exists a controversy over its ideal timing. The aim of our study was to compare the impact of early and late percutaneous tracheotomy in terms of their ability to reduce mechanical ventilation duration and length of stay in Intensive Care Unit, as well as the frequency of ventilator-associated pneumonia and mortality rates in tracheotomized patients. This retrospective observational study indicated that early tracheotomy in surgical and neurosurgical patients was associated with a reduced duration of mechanical ventilation and reduced length of stay in Intensive Care Unit, but was unable to reduce the frequency of ventilator-associated pneumonia and mortality. The reason behind the shorter duration of mechanical ventilation and shorter length of stay in Intensive Care Unit in the early tracheotomy arm was shorter duration of mechanical ventilation carried out prior to tracheotomy, while the duration of mechanical ventilation and the length of stay in Intensive Care Unit after tracheotomy were similar in both groups, suggesting that the procedure itself and not its timing influenced the duration of mechanical ventilation and the length of stay in Intensive Care Unit of tracheotomized patients.

RESUMO

Ventilator-associated pneumonia (VAP) is the most common infection among intensive care unit (ICU) patients. The aim of the present study was to evaluate the impact of tracheotomy on VAP clinical course. The study was conducted in a 15-bed Surgical and Neurosurgical ICU, Department of Anesthesiology and Intensive Care, Sestre milosrdnice University Hospital Center in Zagreb, Croatia. All patients developing VAP during ICU stay were eligible for the study. In VAP patients not tracheotomized during ICU stay, the mortality rate was approximately two times higher as compared with patients tracheotomized either before or after VAP onset (crude risk ratio 1.83, 95% confidence interval (95% CI) 1.15-2.91, p = 0.01; crude odds ratio 3.47, 95% CI 1.52-7.94; p = 0.003). In the surviving VAP patients, the duration of mechanical ventilation before VAP onset was higher in the "T before VAP" group as compared with the "no T before VAP" group (8, 6-10 vs. 3, 2-5; p < 0.001), but the number of post-VAP days on mechanical ventilation was shorter in "T before VAP" patients than in "no T before VAP" patients (0, 0-1 vs. 4, 3-9; p < 0.001). The duration of mechanical ventilation after VAP onset in the "T after VAP" group was longer as compared with the "T before VAP" group (4, 3-12 vs. 0, 0-1; p < 0.001). The present study indicated tracheotomy to be associated with a reduced duration of mechanical ventilation after VAP onset, but only if patients were tracheotomized at the moment of VAP onset.
