    Efeitos da eletroacupuntura, aquapuntura e farmacopuntura em cadelas anestesiadas com isofluorano e submetidas a ovariohisterectomia

    Pain is a protective answer of the organism to harmful impulses, which results in undesirable effects when not controlled. Analgesia can be achieved by utilizing several drugs that may cause adverse effects, according to the patient’s species and physical condition. Acupuncture has been an efficient co-analgesic, as it reduces the amount of drugs utilized to control the pain, without adverse effects. Therefore, we assessed the effects of electroacupuncture, acquapuncture, and pharmacopuncture with morphine in the TA5 and VB41 acupoints, with regards to cardiorespiratory parameters, consumption of isoflurane and analgesia in the immediate postoperation of dogs undergoing ovariohysterectomy. 24 animals were utilized, equally and randomly distributed into four groups (GDest, GMorf, GElet, and GC). Those were anesthetized with acepromazine, propofol, and isoflurane. After the anesthetic plan stabilization, the GDest group animals received 0.5ml of distilled water in each acupoint, the GMorf group animals received morphine in the 0.1mg/kg dose (total dose per animal) diluted in distilled water, whenever required, until reaching the 0.5ml volume in each point, the GElet group animals received impulses by electroacupuncture, and the GC group animals received acupuncture in Sham points. Acupuncture was performed bilaterally In all groups. The GC group animals received 2.0mg/kg of tramadol after surgical procedure completion and before starting the post-operation assessment. The following variables were assessed during trans surgery: Rectal temperature, respiratory rate, heart rate, average blood pressure, blood glucose, oxyhemoglobin saturation, volume of inspired isoflurane vapor, and electrocardiography. The following physiological variables were assessed in postsurgery: Heart and respiratory rates, rectal temperature, and blood glucose. The post-surgery pain assessment was performed by three observers, utilizing the Numerical Analog Scale (Escala de Analogia Numérica (EAN)) and the Melbourne University Pain Scale (Escala de Dor da Universidade de Melbourne). The pain assessment, initiated after animal extubation, was performed during two hours, with 15-minute intervals. There was no static difference among the groups in all trans surgery studied variables, however, the reduction of inspired isoflurane vapor volume of 5.08%, 10.84%, and 25.42% was noticed for the GDest, GMorf, and GElet groups, when compared to the GC group. In the post-surgery, there was no static difference among the groups for all variables. The obtained results demonstrate that electroacupuncture at TA5 and VB41 points, is superior to acquapuncture and pharmacopuncture with morphine in the reduction of inspired isoflurane volume and heart stability, during trans surgery. In immediate post-surgery, the studied techniques result in analgesia similar to tramadol.

    Eletroacupuntura em coelhos submetidos à hipovolemia aguda : avaliação eletrocardiográfica, cardiovascular e microscópica dos sistemas nervoso central e renal

    The effects of the electroacunpuncture of the acupoint Pc6 (Neiguan) and hipertonic saline solution of 7,5% over the electrocardiographic, cardiovascular and microscopic parameters of the CNS and kidneys in rabbits subdued to anesthetics by isofluorane and severe hypovolemia have been evaluated. 24 animals, distributed equally in four groups were used (GH, GE, GS and GC). After stabilization of the anesthetic plan, hypovolemia was induced in the animals with the scope of simulating severe hemorrhage, draining blood from the carotid artery until the average blood pressure reached 35 mmHg. After 30 minutes of hypovolemia, the animals in group GH received 4,0 mL/Kg of hypertonic saline solution in 7,5%, in the infusion speed of 1,0 mL/Kg/min; the ones in the GE group, received acupuncture on the acupoint Pc6, in the frequence of 20 Hz in square wave; the ones in the GS group received acupuncture in the Sham points and the ones in the GC group have not received any treatment. The following variables have been studied: body temperature; f; FC and electrocardiographic trace; PAM; PVC; PVP and serum lactate. The registration of the variables, except for the serum lactate, has started before the production of the hypovolemia and after the anesthetic stabilization of the animals (Mbasal), immediately after the remove of blood (M0), 3 minutes after blood collection (M3), 30 minutes from blood take out and before the beginning of the treatments (M30) and every 10 minutes until 60 minutes from the withdrawal of blood (M40, M50 e M60). Serum lactate has been evaluated in the M0, M3 and M30. After the registry of the variables, euthanasia has been performed to collect from the CNS and kidneys and posterior light microscopy evaluation. For the evaluation of the CNS and kidneys, degenerated neuron count has been performed (front lobe and hippocampus) and cerebellum piriformis neurons (Purkinje cells), and the quantification of the erythrocyte in the glomeruli and in the medullary region between the collection tubules of the kidneys. The statisc evaluation has been performed by profile analysis (P<0,05) and Kolmogorov-Smirnov (P<0,05).There has been no significant difference between the groups and the monets of the studied variables. However, electrocardiographic and cardiovascular alterations have been observed between the M40, M50 and M60 moments in relation to the Mbsal, observing increase in the PAM, PVC e blood lactate variables, and compensatory responses in the variables of the electrocardiogram. In the CNS, no significant differences related to the brain region between the studied groups have been observed. In relation to the kidney microscopy, there were no significant difference in relation to the quantity of erythrocytes between the glomeruli and kidney tubules. However, in the GE group a greater quantity of erythrocytes has been noticed. Thus, as a conclusion, the electro stimulation of the Pc6 acupoint and the hypertonic 7,5% solution do not cause alterations on the electrocardiographic and cardiovascular parameters; and electroacupuncture improves perfusion in the renal of rabbits subdued to severe hemorrhage.
