The Effect of Intravenous Tranexamic Acid on Perioperative Blood Loss, Transfusion Requirements, Verticalization, and Ambulation in Total Knee Arthroplasty: A Randomized Double-Blind Study.

Total knee arthroplasty (TKA) is sometimes associated with significant perioperative bleeding. The aim of this study was to determine the efficacy of tranexamic acid (TXA) in reducing perioperative blood loss in patients undergoing primary TKA. The secondary objectives were to assess the efficacy of TXA in reducing the need for blood transfusion in these patients and to determine its effect on verticalization and ambulation after TKA.

The Effect of Recruitment Maneuver on Static Lung Compliance in Patients Undergoing General Anesthesia for Laparoscopic Cholecystectomy: A Single-Centre Prospective Clinical Intervention Study.

: The aim of this study was to examine whether the use of an alveolar recruitment maneuver (RM) leads to a significant increase in static lung compliance (Cstat) and an improvement in gas exchange in patients undergoing laparoscopic cholecystectomy. : A clinical prospective intervention study was conducted. Patients were divided into two groups according to their body mass index (BMI): normal-weight (group I) and pre-obese and obese grade I (group II).

Erector spinae plane block reduces pain after laparoscopic cholecystectomy.

Purpose: After laparoscopic cholecystectomy patients have moderate pain in the early postoperative period. According to several studies an erector spinae plane (ESP) block can be a valuable part of multimodal analgesia. Our intention was to evaluate how ESP block influences postoperative pain scores and opioid consumption after laparoscopic cholecystectomy.

[Subcostal transversus abdominis plane block can improve analgesia after laparoscopic cholecystectomy].

Background And Goal Of Study: After laparoscopic cholecystectomy, patients have moderate pain in the early postoperative period. Some studies shown beneficial effects of subcostal transversus abdominis plane block on reducing this pain. Our goal was to investigate influence of subcostal transversus abdominis plane block on postoperative pain scores and opioid consumption.

Magnesium Sulfate as an Adjuvant to Anesthesia in Patients with Arterial Hypertension.

There is limited evidence showing that elevated arterial blood pressure in surgical patients may be associated with increased perioperative risk; however, cardiovascular instability frequently occurs during anesthesia. The most commonly used anesthetic agents, both intravenous and inhalation ones, produce a decrease in arterial blood pressure. Magnesium, acting as a natural calcium-channel blocker, induces direct and indirect vasodilatation, thus playing a role in the treatment of arterial hypertension.

Cardiovascular effects of methadone and concomitant use of diazepam during methadone maintenance treatment induction: low concentration risk.

Background: The aim is to evaluate the role of diazepam concentrations in development of low-concentration-methadone-associated QTc prolongation in patients with opioid use disorder during methadone maintenance treatment (MMT) induction.

Research Design And Methods: Individuals with addiction disorder on MMT were studied before the beginning of MMT and after one and six months of MMT. Serum concentrations of methadone, diazepam, electrolytes and ECG were analyzed.

Use of presepsin and procalcitonin for prediction of SeptiFast results in critically ill patients.

Purpose: There is a need for identification of marker that could lead physicians to take the right step towards laboratory techniques for documentation of infection. The aim of this study was to investigate whether presepsin and procalcitonin (PCT) levels in patients with suspected sepsis could predict blood culture (BC) and SeptiFast (SF) results.

Material And Methods: 100 patients were included in our study.

Acquired prolongation of QT interval as a risk factor for torsade de pointes ventricular tachycardia: a narrative review for the anesthesiologist and intensivist.

More than 70% of intensive care unit (ICU) patients experience heart rhythm disturbances, and these patients have correspondingly higher mortality rates. Consequently, one of the standards of care in ICUs is continuous electrocardiography monitoring. One of the potentially preventable dysrhythmic events is the occurrence of torsade de pointes ventricular tachycardia in the setting of acquired prolonged QT interval.

A case of recurrent arrhythmia in an acute pancreatitis patient--pathophysiological explanation using shortage of 'repolarization reserve'.

We report a case of a patient with acute pancreatitis who developed serious heart rhythm abnormalities on three occasions, two of which were associated with administration of the first generation antihistamine chloropyramine, and the third one with hypomagnesemia and hypokalemia. Dysrhythmic events consisted of bigeminy, multifocal ventricular extrasystoles and torsades de pointes-like ventricular tachycardia. Electrocardiographic changes in acute pancreatitis in the absence of previous heart disease can occur in more than half of the cases.

Clinical and predictive significance of hyponatremia after aneurysmal subarachnoid hemorrhage.

Objective: Hyponatremia after SAH was the object of several studies with conflicting results. The aim of this study was to determine a predictive correlation of hyponatremia with delayed cerebral ischemia (DCI) and poor clinical outcome.

Material And Methods: We have used a retrospective hospital chart review of 82 patients with SAH treated from August 2008 to August 2010.
