Guidelines for Anesthesia in Critically Ill Feline Patients

AAFP Feline Anesthesia Guidelines

“…However, if during anesthesia the heart rate increases above 220 bpm with an adequate depth of anesthesia, start a constant rate infusion (CRi) of esmolol with a loading dose of 0.1-0.5 mg/kg iV over 1 min, followed by a CRi of 100-200 µg/kg/min. 36,45,46 Renal disease 33,39 Preanesthetic fluid therapy may be of value to restore normovolemia and hydration.…”

“…At blood glucose levels between these extremes balanced electrolyte solutions with or without dextrose (2.5-5%) can be used based on results of monitoring. 49 Asthma or lower airway disease 39,50 Complications related to sedation and/or general anesthesia can be significantly increased in cats with lower airway disease. Although there are no specific anesthetic protocols in veterinary medicine for asthma, as there are in people, there are some recommendations: < Maintain the patient on its asthma management medications up to and including the morning of anesthesia.…”

“…one study found that 68.8% of cats selected for DJD studies also had concurrent chronic kidney disease. 54 Urinary obstruction 33,39,55,56 Although one of the goals of therapy in obstructed cats is to restore urine flow, simply restoring urine flow and not correcting dehydration and electrolyte abnormalities appears to be associated with poor outcomes. in addition, if there are electrocardiographic changes related to hyperkalemia or the blood potassium concentration is >7 mEq/l (mmol/l), institute immediate therapy to protect the heart and to lower the serum potassium concentration prior to sedation or anesthesia.…”

Particularidades da anestesia em felinos

“…Pacientes ansiosos geralmente requerem altas doses de sedativos ou tranquilizantes, o que pode causar depressão respiratória e cardiovascular (Grubb et al, 2020) Numerosas condições médicas e ambientais podem provocar respostas agressivas nesses pacientes (Kushner, 2010a). Dessa forma, o gato agressivo representa um desafio para a realização de tarefas não invasivas sem boa contenção química (Pypendop & Ilkiw, 2015).…”

“…Sedação leve a moderada é recomendada para facilitar exames radiográficos, ultrassonográficos ou para aplicação de curativos ou talas; sedação intensa fica recomendada para procedimentos como cateterização uretral para desobstrução uretral, punção biópsia por agulha fina, punção de medula óssea, toracocentese e etc. (Kushner, 2010a).…”
