The Pleth Variability Index as a Guide to Fluid Therapy in Dogs Undergoing General Anesthesia: A Preliminary Study.

The aim of this prospective, randomized clinical trial was to evaluate the use of the pleth variability index (PVi) to guide the rate of intraoperative fluid therapy compared to a traditional fixed-fluid-rate approach in ASA 1-2 dogs undergoing surgery. Twenty-seven dogs met the inclusion criteria and were randomly assigned to the conventional fluid management group (CFM, = 12) or the PVi-guided group (PVi, = 15). The CFM group received a fixed rate of 5 mL kg h of crystalloid solution, while in the PVi group the rate was continuously adjusted based on the PVi: PVi < 14% = 3 mL kg h; 14% ≤ PVi ≥ 20% = 10 mL kg h; and PVi > 20% = 15 mL kg h.

Total Laparoscopic Colopexy for the Treatment of Recurrent Rectal Prolapses in Three Cats.

The use of minimally invasive methods has grown in popularity due to decreased postoperative morbidity and a quicker recovery. Colopexy is a surgical method that includes the permanent adhesion of the colonic seromuscular layer to the abdominal wall to avoid rectal prolapses in cats and dogs with viable prolapsed tissues. In this case series, we describe the treatment of three cats with total laparoscopic colopexy (TLC) for recurrent rectal prolapses.

The incidence of hypoxemia in dogs recovering from general anesthesia detected with pulse-oximetry and related risk factors.

The postoperative period is critical for the development of complications, including hypoxemia. To detect hypoxemia early and provide appropriate care, continuous monitoring of saturation is necessary: pulse oximetry is an easily accessible and simple method for this purpose. However, a SpO cut-off value to detect hypoxemia in dogs recovering from general anesthesia is lacking in the veterinary literature.

Respiratory Effects of Continuous Positive Airway Pressure Administered during Recovery from General Anesthesia in Brachycephalic Dogs.

This study aimed to evaluate the benefits of applying 5 cmHO of CPAP using a pediatric helmet during the recovery phase from general anesthesia in brachycephalic dogs. Brachycephalic dogs undergoing various surgical procedures were included in this study, and a total of 64 subjects were randomly assigned to receive either standard oxygen supplementation (NO-CPAP group) or oxygen supplementation combined with CPAP (CPAP group). This study evaluated arterial blood pH, blood gas partial pressures of O and CO, arterial blood O saturation, and related parameters during recovery.

Temporal association between drops in thoracic impedance and malignant ventricular arrhythmia: A longitudinal analysis of remote monitoring trends.

Introduction: Thoracic impedance (TI) drops measured by implantable cardioverter-defibrillators (ICDs) have been reported to correlate with ventricular tachycardia/fibrillation (VT/VF). The aim of our study was to assess the temporal association of decreasing TI trends with VT/VF episodes through a longitudinal analysis of daily remote monitoring data from ICDs and cardiac resynchronization therapy defibrillators (CRT-Ds).

Methods And Results: Retrospective data from 2384 patients were randomized 1:1 into a derivation or validation cohort.

Use and Prescription of Direct Oral Anticoagulants in Older and Frail Patients with Atrial Fibrillation: A Multidisciplinary Consensus Document.

In the last twelve years the clinical management of patients with atrial fibrillation has been revolutionised by the introduction of direct oral anticoagulants. Despite the large amount of evidence produced, some populations remain relatively poorly explored regarding the effectiveness and safety of direct oral anticoagulants, such as the oldest and/or frailest individuals. Frailty is clinical syndrome characterized by a reduction of functions and physiological reserves which results in individuals having higher vulnerability.

Rhythm-control vs rate-control in the elderly: When to do it and which drug to prefer?

Atrial fibrillation (AF) is a relevant cardiovascular condition that is more prevalent in the elderly patients aged over 65 years. AF, with abnormal rate and rhythm can cause symptoms directly or indirectly by exacerbating other frequently coexisting cardiac conditions such as valvular heart disease, hypertension, ischemic cardiomyopathy, dilated cardiomyopathy, and hypertrophic cardiomyopathy. Evidence suggests that aging-related cardiovascular changes predispose to the elderly to AF.
