Avaliação dos efeitos analgésicos intraoperatórios da eletroacupuntura perioperatória: um ensaio clínico randomizado e cego em cães

Resumo original em inglês

O que aconteceu

To evaluate the effect of perioperative electroacupuncture (EA) on intraoperative analgesic requirements in dogs undergoing tibial tuberosity advancement (TTA) surgery.

Prospective, randomised, blinded, controlled clinical study.

A group of 29 client-owned dogs diagnosed with cranial cruciate ligament rupture that underwent TTA surgery.

Dogs were treated with EA at predefined acupuncture points (LI-4, ST-36, LIV-3, SP-6 and GB-34) perioperatively as additional analgesia (group EA, n = 14) or were allocated to the control group (group C, n = 15). All dogs were anaesthetised with a standardised protocol including methadone, dexmedetomidine, propofol and ketamine. The intraoperative delivery of sevoflurane and fentanyl was guided in response to signs of nociception by a purpose-designed flowchart, by the same anaesthetist who was blinded to treatment group. A Wilcoxon rank sum test was applied for the fentanyl consumption analysis. Heart rate, mean arterial blood pressure and end-tidal sevoflurane were descriptively analysed between groups for specific time points. A p value < 0.05 was considered significant.

O que encontraram

The EA group needed significantly less fentanyl with 0.7 (0-2.7) μg kg-1 hour-1 administered versus 2.0 (1.2-5.5) μg kg-1 hour-1 in group C (p = 0.031). Fifty percent of the EA group was not administered a fentanyl bolus, whereas all dogs in group C required at least one bolus.

Por que isso importa

Perioperative EA reduced mean fentanyl consumption by more than 60% in dogs undergoing TTA surgery.
