#1
Cristina Caldararu, Serban Balanescu
Echocardiography is the cornerstone in the diagnosis of any valvular heart disease. The accurate diagnosis of aortic stenosis, the left ventricle function and the other heart valves evaluation are currently done by ultrasound alone. Prosthetic valve choice and dimensions prior to implantation can be done solely by proper use of echocardiography. The emergence of new methods to cure aortic stenosis such as trans-catheter aortic valve replacement (TAVR) emphasized the diagnostic value of cardiac ultrasound. The usefulness of echocardiography in TAVR can be divided in the baseline assessment (common to patients treated by conventional surgery), intra-procedural guidance of valve deployment and post-procedural follow-up...

A 40-year-old female patient was admitted to the authors' oral and maxillofacial clinic for removal of her lower left second molar under local anesthesia. The patient's medical history revealed that she had cardiac arhythmia and hypertension. Inferior alveolar nerve block was achieved using 2 mL of sefacaine (%3 mepivacaine HCL, without epinephrine). The patient complained of loss of vision in her left eye. All procedures were stopped immediately. Within 2 minutes the patient reported diplopia. All of the symptoms disappeared about 5 minutes after initial observation...

BACKGROUND: Pneumoperitoneum during laparoscopic cholecystectomy (LC) can cause hypercapnia, hypoxemia, hemodynamic changes and shoulder pain. General anesthesia (GA) enables the control of intraoperative pain and ventilation. The need for GA has been questioned by studies suggesting that neuraxial anesthesia (NA) is adequate for LC. STUDY OBJECTIVE: To quantify the prevalence of intraoperative pain and to verify whether evidence on the maintenance of ventilation, circulation and surgical anesthesia during NA compared with GA is consistent...

The choice of inodilator drug in the acute management of patients with pulmonary hypertension (PH) having right ventricular (RV) failure remains unsettled and challenging. Comprehensive experimental evaluations may provide further insight and fundamental translational research clues to support inodilator selection and clinical trial design. Our aim was to compare acute dose-response hemodynamic effects of inodilators dobutamine (DOB), milrinone (MIL), and levosimendan (LEV) in chronic experimental PH. Seven-week-old male Wistar rats were randomly injected with 60 mg·kg(-1) monocrotaline (MCT) or vehicle (Ctrl, n = 7) and underwent systemic and pulmonary artery (PA) pressure and RV pressure-volume (PV) hemodynamic evaluation under halogenate anesthesia 24 to 30 days after injection...

BACKGROUND: Passive regurgitation may occur throughout the perioperative period, increasing the risk for pulmonary aspiration and postoperative pulmonary complications. Hypnotics and opioids, especially remifentanil, that are used during anesthesia have been shown to decrease the pressure in the esophagogastric junction (EGJ), that otherwise acts as a barrier against passive regurgitation of gastric contents. Esmolol, usually used to counteract tachycardia and hypertension, has been shown to possess properties useful during general anesthesia...

Perioperative hypertension is a phenomenon in which a surgical patient's blood pressure temporarily increases throughout the preoperative and postoperative periods and remains high until the patient's condition stabilizes. This phenomenon requires immediate treatment not only because it is observed in a majority of patients who are not diagnosed with high blood pressure, but also because occurs in patients with underlying essential hypertension who show a sharp increase in their blood pressure. The most common complication following facelift surgery is hematoma, and the most critical risk factor that causes hematoma is elevated systolic blood pressure...

Reversible cerebrovascular vasoconstriction syndrome is an uncommon condition that presents as severe headache and hypertension. Recent literature suggests a 1% incidence in postpartum headache cases. It can cause subarachnoid hemorrhages, cerebral ischemia, and seizures. It is often misdiagnosed as postdural puncture headache or preeclampsia. In this case, a postpartum woman, who had received epidural anesthesia for labor, presented 5 days postpartum with severe headache that did not resolve with an epidural blood patch...

Maternal mortality is increasing in the United States and remains unacceptably high in many parts of the world. Pre-existing conditions and social determinants of health frequently contribute to maternal death. General solutions to enhance maternal safety focus on systems to identify women at high risk and to tailor the management before, during, and after pregnancy. This review highlights condition-specific solutions for the leading etiologies of maternal death, including cardiac disease, sepsis, hemorrhage, venous thromboembolism, hypertensive disorders of pregnancy, and amniotic fluid embolism...
