Parental Presence during Induction of Anesthesia and Emergence Delirium Influence the Incidence of Postoperative Maladaptive Behavioral Changes.

OBJECTIVE: Surgical intervention in pediatric patients can cause variable degrees of psychological stress with potential consequences in the perioperative period and even in the long term, after hospital discharge in the form of behavioral changes days and months later. The aim of our study was to determine which preoperative preparation strategy reduces postoperative maladaptive behavioral changes in children undergoing ambulatory pediatric surgery. MATERIALS AND METHODS: This prospective observational study included 638 pediatric American Society of Anesthesiologists physical status I or II patients who underwent ambulatory pediatric surgery. They were grouped into four preoperative preparation groups: not premedicated (NADA), premedicated with midazolam (MDZ), parental presence during induction of anesthesia (PPIA), and parental presence during induction of anesthesia and premedicated with midazolam (PPIA + MDZ). All patients included in the study were contacted by telephone during 1 year posthospital discharge to assess the postoperative maladaptive behavioral changes using the Posthospitalization Behavior Questionnaire (PHBQ). We performed a multivariate analysis to evaluate the influence of type of preparation and behavioral changes. RESULTS: Patients in the PPIA and PPIA + MDZ preparation groups presented less postoperative maladaptive behavioral changes compared to patients in the NADA and MDZ groups (odds ratio [OR]: 1.8 [1.1-2.8] and OR 2.2 [1.03-4.49]) during the first week and first month. The intensity of emergence delirium measured by the Pediatric Anesthesia Emergence Delirium (PAED) scale increases the probability of postoperative maladaptive behavioral changes (OR: 1.05 [1.006-1.103]). CONCLUSION: The presence of parents during induction of anesthesia (PPIA and PPIA + MDZ) is a very effective strategy in reducing postoperative behavioral changes. These benefits are more significant in children under 5 years of age.

Parental Presence during Induction of Anesthesia Improves Compliance of the Child and Reduces Emergence Delirium.

INTRODUCTION: Preoperative stress and anxiety in pediatric patients are associated with poor compliance during induction of anesthesia and a higher incidence of postoperative maladaptive behaviors. The aim of our study was to determine which preoperative preparation strategy improves compliance of the child during induction and decreases the incidence and intensity of emergence delirium (ED) in children undergoing ambulatory pediatric surgery. MATERIALS AND METHODS: This prospective observational study included 638 pediatric American Society of Anesthesiologists I-II patients who underwent ambulatory pediatric surgery, grouped into four preoperative preparation groups: NADA (not premedicated), MDZ (premedicated with midazolam), PPIA (parental presence during induction of anesthesia), and PPIA + MDZ. The results were subsequently analyzed in four age subgroups: Group 1 (0-12 months), Group 2 (13-60 months), Group 3 (61-96 months), and Group 4 (> 96 months). Preoperative anxiety (modified Yale Preoperative Anxiety Scale [m-YPAS]), compliance of the child during induction (Induction Compliance Checklist [: ICC]), and ED (Pediatric Anesthesia Emergence Delirium scale) were analyzed in each group. RESULTS: Eighty-one percent of patients in the PPIA + MDZ preparation group presented a perfect compliance during the induction of anesthesia (ICC = 0), less preoperative anxiety (mean score m-YPAS = 26), less probability of ED (odds ratio: 10, 5 [3-37.5]; p < 0.05), and less ED intensity compared with the NADA group (1.2 vs. 5.8; p = 0.001). CONCLUSION: PPIA associated with midazolam premedication improves compliance during induction and decreases the incidence and intensity of ED.

Successful systemic fibrinolysis in a patient with Covid-19: Case report / Fibrinólisis sistémica exitosa en un paciente con Covid- 19: Reporte de Caso

Abstract The new coronavirus 2019-nCov or SARS-Cov-2 is responsible for the most important pandemic in the 21st century: the coronavirus disease (COVID-19). The 2019-nCov infection elicits a hyper-coagulable state, conditioning a worse outcome in these patients. The pathophysiology of the exaggerated coagulation activation in these patients is still unknown, and probably involves several mechanisms, different from those involved in sepsis-associated coagulopathy. This article discusses the case of a patient with no remarkable medical history, who after 7 days of fever, diarrhea and epigastric pain was diagnosed with COVID-19 bilateral pneumonia, further aggravated by severe Acute Respiratory Distress Syndrome. In this context, the patient experienced a massive acute pulmonary thromboembolism accompanied by an acute thrombus in the heart's right ventricle, leading to hemodynamic instability. For the first time in our center in these patients, systemic fibrinolysis was successfully performed, with resolution of the intracavitary thrombus and the acute hemodynamic shock.

Resumen El nuevo coronavirus 2019-nCov o SARS-Cov-2 es responsable de la pandemia más importante del siglo XXI: la enfermedad del coronavirus (COVID-19). La infección por 2019-nCov produce un estado de hipercoagulabilidad, que promueve peores desenlaces en estos pacientes. La fisiopatología de la exagerada activación de la coagulación en estos pacientes aún se desconoce y posiblemente involucre varios mecanismos, diferentes a los participan en la coagulopatía asociada a sepsis. El presente artículo presenta el caso de un paciente sin antecedentes médicos y quien luego de 7 días de fiebre, diarrea y dolor epigástrico, fue diagnosticado con neumonía bilateral por COVID-19, agravada por la presencia de Síndrome de Dificultad Respiratoria Aguda. En este contexto, el paciente desarrolla un tromboembolismo pulmonar agudo masivo, acompañado de un trombo agudo en el ventrículo derecho, produciéndole inestabilidad hemodinámica. Por primera vez en nuestro centro, se realizó exitosamente una fibrinólisis sistémica, con resolución del trombo intracavitario y del shock hemodinámico agudo.

Infratrochlear neuralgia: A prospective series of seven patients treated with infratrochlear nerve blocks.

Background Infratrochlear neuralgia is a recently described painful cranial neuropathy that causes pain in the internal angle of the orbit and the medial upper eyelid, the upper bridge of the nose and/or the lacrimal caruncle. We aim to present seven new cases of infratrochlear neuralgia treated with anaesthetic nerve blocks. Methods Over an 18-month period, we prospectively identified seven cases of infratrochlear neuralgia among the patients attending the Headache Unit in a tertiary hospital. Anaesthetic blocks were performed by injecting 0.5 cc of bupivacaine 0.5% at the emergence of the nerve above the internal canthus. Results All patients were women, and the mean age was 49.1 years (standard deviation, 17.9). The pain appeared at the internal angle of the orbit and/or the medial upper eyelid in six cases, and the whole territory of the infratrochlear nerve in one case. Six patients had continuous pain and one had episodes lasting 8-24 hours. All patients showed sensory disturbances within the painful area and tenderness upon palpation of the infratrochlear nerve. Nerve blocks resulted in complete and long-lasting relief in four patients and short-lasting relief in the other three patients. Conclusions Infratrochlear neuralgia should be considered among the neuralgic causes of orbital and periorbital pain. Anaesthetic blocks may assist clinicians in the diagnosis and may also be an effective therapy.

Supratrochlear Neuralgia: A Prospective Case Series of 15 Patients.

OBJECTIVE: The aim of this study was to describe clinical features unique to supratrochlear neuralgia. BACKGROUND: The supratrochlear nerve supplies the medial aspect of the forehead. Due to the intricate relationship between supraorbital and supratrochlear nerves, neuralgic pain in this region has been traditionally attributed to supraorbital neuralgia. No cases of supratrochlear neuralgia have been reported so far. METHODS: From 2009 through 2016, we prospectively recruited patients with pain confined to the territory of the supratrochlear nerve. RESULTS: Fifteen patients (13 women, 2 men; mean age 51.4 years, standard deviation 14.9) presented with pain in the lower paramedian forehead, extending to the eyebrow in two patients and to the internal angle of the orbit in another. Pain was unilateral in 11 patients (six on the right, five on the left), and bilateral in four. Six patients had continuous pain and nine described intermittent pain. Palpation of the supratrochlear nerve at the medial third of the supraorbital rim resulted in hypersensitivity in all cases. All but one patient exhibited sensory disturbances within the painful area. Fourteen patients underwent anesthetic blockades of the supratrochlear nerve, with immediate relief in all cases and long-term remission in three. Six of them had received unsuccessful anesthetic blocks of the supraorbital nerve. Five patients were treated successfully with oral drugs and one patient was treated with radiofrequency. CONCLUSIONS: Supratrochlear neuralgia is an uncommon disorder causing pain in the medial region of the forehead. It may be differentiated from supraorbital neuralgia and other similar headaches and neuralgias based on the topography of the pain and the response to anesthetic blockade.

Amyloid- and FDG-PET in sporadic Creutzfeldt-Jakob disease: Correlation with pathological prion protein in neuropathology.

INTRODUCTION: The role of positron emission tomography (PET) in Creutzfeldt-Jakob disease is less defined than in other neurodegenerative diseases. We studied the correlation between the uptake of 18F-florbetaben and 18F-fluorodeoxyglucose with pathological prion protein deposition in histopathology in a case. METHODS: A patient with 80 y old with a rapid neurological deterioration with a confirmed diagnosis of CJD was studied. PET and MRI studies were performed between 13-20 d before the death. A region of interest analysis was performed using Statistical Parametric Mapping. RESULTS: MRI showed atrophy with no other alterations. FDG-PET showed extensive areas of hypometabolism including left frontoparietal lobes as well as bilateral thalamus. Correlation between uptake of 18F-florbetaben and pathological prion protein deposition was r = 0.786 (p < 0.05). Otherwise, correlation between uptake of 18F-FDG and pathological prion protein was r = 0.357 (p = 0.385). Immunohistochemistry with ß-amyloid did not show amyloid deposition or neuritic plaques. CONCLUSIONS: Our study supports the use of FDG-PET in the assessment of CJD. FDG-PET may be especially useful in cases of suspected CJD and negative MRI. Furthermore, this case report provides more evidence about the behavioral of amyloid tracers, and the possibility of a low-affinity binding to other non-amyloid proteins, such as the pathological prion protein, is discussed.
