Analgesia transoperatória e estabilidade anestésica de gatas tratadas com eletroacuputura

Abstract

The aim of this study was to evaluate analgesia and anesthesia stability from acupoints electrostimulation IG4, C7, PC6 (G1) and BP6, E36 and VB34 (G2) on 12 healthy cats submitted to ovariohysterectomy (OH). Electroacupuncture (EA) was performed with frequencies 3 and 300 Hz, 20 min before starting surgery, remaining until the end. The parameters RR, HR, SBP and RT were measured in M0 (basal), M1 (15 min after PAM), M2 (immediately before EA), M3 (20 min after EA) and M4 on every 10 min. From M2, ETISO, ETCO2 and SpO2 were also evaluated. Times were recorded as: Anesthetic Adjustment (TAA); Total Surgery (TTC); Total Anesthesia (TTA); Extubation (TE) and Total Recovery (TTR). Acepromazine (MPA), propofol (induction) and isoflurane (maintenance) were administered. In both groups, there was a decrease from RR and HR in M3 and from SBP in M2, in relation to M0, hypotension persisted, progressive decrease from RT, ETISO mean 1.48V% in G1 and 1.56% in G2 and hypocapnia. It was concluded that the two electrostimulation protocols promoted transurgical analgesia with consequent isoflurane consumption reduction, but with hypotensive effect.
