Goats have been used as animal models in research and are increasingly kept as companion animals. However, information about effective anesthetic drugs is scarce in this species. The objective of this study was to evaluate the effect of xylazine premedication on alfaxalone induction. Twelve clinically healthy goats weighing 18.5 ± 2 kg were randomly assigned to two groups. Induction was performed with alfaxalone alone intravenously (ALF group) or with xylazine premedication before alfaxalone administration (XYL-ALF group). The quality of induction was scored, induction doses of alfaxalone were determined, and cardiorespiratory parameters and nociceptive thresholds were measured before any treatment(s) (baseline) and at 5, 15, 25 and 35 min after alfaxalone administration. The mean dose of alfaxalone required for induction in the ALF group was greater than that in the XYL-ALF group (p < 0.001). There were no significant changes in diastolic arterial pressure (DAP), mean arterial pressure (MAP) or systolic arterial pressure (SAP) compared to baseline in either group, while hemoglobin oxygen saturation (SpO2) was lower from 5 to 25 min (p < 0.5) in the XYL-ALF group. The nociceptive threshold was significantly higher at 5 min in the XYL-ALF group than in the ALF group (p = 0.0417). Xylazine premedication reduced the required dose of alfaxalone for anesthetic induction and produced better antinociception than alfaxalone alone. In addition, the combination of xylazine and alfaxalone allowed for successful induction; however, oxygen supplementation is necessary to counteract xylazine-associated hypoxemia.

The incidence rates of spinal anaesthesia-induced hypotension vary depending on the surgical procedures. This systematic review and meta-analysis evaluates the efficacy of prophylactic ondansetron in reducing the incidence of spinal anaesthesia-induced hypotension in non-caesarean delivery. Thirteen trials consisting of 1166 patients were included for analysis. Compared to placebo, there is a low quality of evidence that ondansetron was effective in reducing the incidence of spinal anaesthesia-induced hypotension (RR 0.62, 95% CI 0.44 to 0.87; p = 0.005) and bradycardia (RR 0.54, 95% CI 0.32 to 0.90; p = 0.02). We also found a moderate quality of evidence that ondansetron lowered the number of rescue ephedrine (RR 0.61, 95% CI 0.43 to 0.87; p = 0.007). Patients treated with ondansetron have higher mean arterial pressure 15 to 20 minutes after spinal anaesthesia induction and higher systolic arterial pressure 5, 10, 15 and 20 minutes after spinal anaesthesia. The evidence suggests that prophylactic administration of ondansetron results in the reduction of the incidence of spinal anaesthesia-induced hypotension, bradycardia and rescue ephedrine in patients undergoing non-caesarean delivery under spinal anaesthesia.

Total intravenous anesthesia (TIVA) is increasingly used in companion animals. The effect of electroacupuncture (EA) on alfaxalone-based TIVA has not been previously reported in goats. Therefore, the objective of this study was to determine the minimum infusion rate (MIR) of alfaxalone required to prevent purposeful movement of the extremities in response to standardized noxious stimulation during its combination with EA in goats. Twelve clinically healthy goats weighing 18.5 ± 2 kg were randomly assigned to two groups (six goats/group). Alfaxalone alone (ALF group) and alfaxalone combined with EA (EA-ALF group). In the EA-ALF, alfaxalone was administered 30 min after EA stimulation. For induction of anesthesia, a bolus of alfaxalone was given at 3 mg/kg IV, and an infusion dose of 9.6 mg/kg/h was initially set for maintenance. The MIR of alfaxalone in both groups was determined by testing for responses to stimulation (clamping on a digit with Vulsellum forceps) at 10-min intervals after induction of anesthesia till the entire period of the experiment. Cardiopulmonary parameters and nociceptive threshold were measured throughout anesthesia. The median alfaxalone MIR was significantly lower in the EA-ALF group than the ALF group [9 (4.8–9.6) and 12 (11.4–18)], respectively; p = 0.0035). In the ALF group, goats anesthetized with MIR showed a significant increase in heart rate and cardiac output (p < 0.0001 and 0.0312, respectively), and decrease in respiratory rate (p < 0.0001), hemoglobin oxygen saturation (p = 0.0081), and rectal temperature (p = 0.0046) compared with those in the EA-ALF. Additionally, goats in the EA-ALF showed a higher nociceptive threshold than those in the ALF group (p < 0.0001). EA provided analgesia, reduced the MIR of alfaxalone-based IV anesthesia and thereby alleviated the adverse cardiorespiratory effects associated with alfaxalone anesthesia in goats.

Background In our routine practice, we observed a reduced incidence of fetal acidosis (umbilical artery pH &lt; 7.20) at cesarean delivery during spinal anesthesia when a combination of phenylephrine and ephedrine was used as first line vasopressor therapy, compared with using ephedrine alone. Methods The study was randomized and double blind. It compared phenylephrine 100 microg/ml (phenylephrine group), ephedrine 3 mg/ml (ephedrine group), and phenylephrine 50 microg/ml combined with ephedrine 1.5 mg/ml (combination group), given by infusion, to maintain maternal systolic arterial pressure at baseline during spinal anesthesia for elective cesarean delivery. Results Fetal acidosis was less frequent in the phenylephrine group (1 of 48) (P = 0.004) and less frequent in the combination group (1 of 47) (P = 0.005) than in the ephedrine group (10 of 48). The mean systolic arterial pressure was similar for the three groups: Phenylephrine group median 98% (IQR 94-103) of baseline, ephedrine group 100% (96-106) and combination group 101% (97-108) (P = 0.11). The mean heart rate was higher in the ephedrine group (median 107% [IQR 99-118] of baseline) than in the phenylephrine group (88% [82-98]) (P &lt; 0.0001), or the combination group (96% [86-102]) (P &lt; 0.0001). Nausea and vomiting were less frequent in the phenylephrine group (nausea 17%, vomiting 0%) than in the ephedrine group (nausea 66%, vomiting 36%) (P &lt; 0.0001), or the combination group (nausea 55%, vomiting 18%) (P &lt; 0.0001). Conclusions Giving phenylephrine alone by infusion at cesarean delivery was associated with a lower incidence of fetal acidosis and maternal nausea and vomiting than giving ephedrine alone. There was no advantage to combining phenylephrine and ephedrine because it increased nausea and vomiting, and it did not further improve fetal blood gas values, compared with giving phenylephrine alone.

This study aimed to compare, first, the anesthetic and cardiopulmonary effects of propofol or isoflurane anesthetic maintenance in goats receiving a fentanyl–lidocaine–ketamine infusion undergoing abomasotomy and, secondly, to compare the quality of the recovery from anesthesia. Two groups were used: propofol (TIVA) and isoflurane (PIVA). Goats were premedicated with fentanyl (10 μg/kg intravenously [IV]), lidocaine (2 mg/kg, IV), and ketamine (1.5 mg/kg, IV). Anesthesia was induced with propofol and maintenance consisted of fentanyl (10 μg/kg/h, IV), lidocaine (50 μg/kg/min, IV), and ketamine (50 μg/kg/min, IV) as constant-rate infusions (CRIs), combined with either CRI of propofol at initial dose of 0.3 mg/kg/min, IV (TIVA), or isoflurane with initial end-tidal (FE’Iso) concentration of 1.2% partial intravenous anesthesia (PIVA). The mean effective propofol dose for maintenance was 0.44 ± 0.07 mg/kg/min, while the mean FE’Iso was 0.81 ± 0.2%. Higher systolic arterial pressure (SAP) values were observed in total intravenous anesthesia (TIVA) during some time points. Recovery was smooth in PIVA, while restlessness, vocalizations, and paddling were observed in TIVA. Both protocols produced a satisfactory quality of anesthesia during surgery, with minimal impact on cardiopulmonary function. Nevertheless, recovery after anesthesia in TIVA might be of poor quality.

IntroductionThe electroconvulsive therapy (ECT) is an effective treatment used for several psychiatric disorders. However, there are multiple enigmas about the mechanisms of action and factors that improve its results. Some frequent questions are if the anesthetic drug makes a difference in the time of convulsion and blood pressure.AimsOur principal aim is to describe the utilization of anesthetic drugs among the patients that are being treated with ECT in hospital del Mar. We also want to know the differences in the time of convulsion and systolic arterial pressure for every anesthetic drug (propofol, thiopental and etomidate).Material and methodsWe have used the database of ECT in hospital del Mar. It contains information like age, principal diagnosis, medical background and pharmacological treatment at the moment of starting ECTs; it also contains information of each individual ECT session as basal, 2 and 5 minutes arterial pressure; the anesthetic drug used, and convulsion duration.We made an analysis of general conditions of the population, the differences of convulsion time and arterial pressure between the three anesthetic drugs.ResultsPropofol was used in 1140 sessions, thiopental in 61 sessions and etomidate in 54 sessions. The differences in the means of convulsion times between propofol and etomidate are statistically significant (“P” value < 0.05). Etomidate or thiopental increases the difference of arterial pressure more than propofol.ConclusionsFurther research about the factors that improve convulsion duration and minimize adverse effects on blood pressure is needed.Disclosure of interestThe authors have not supplied their declaration of competing interest.

ABSTRACT: This study evaluated the quality of anesthesyc recovery of horses using a three-point assisted method. Sixty-eight horses (37 females and 31 males) of different breeds, age and weight submitted to general anesthesia for abdominal - ABD (n=15), arthroscopy - ART (n=17), other orthopedic - ORT (n=18) and miscellaneous - MIX (n=18) surgical procedures. Isoflurane resulted in shorter recovery time (67.4±25.7min) compared to halothane (88.0±37.8min). The mean duration (±SD) of anesthesia for ABD, ORT, ART and MIXgroups was 166.7 (±14), 54.9 (±5.9), 86.5 (±7.3) and 76.4 (±32.5) minutes (min) respectively. Quality of recovery wasn’t influenced by duration of anesthesia or by use of analgesic, sedative and/or anesthetic drugs or not (p>0.05). Mean standing time (TEst) during anesthetic recovery was 67.5 (±29.9) min in ABD, 44.4 (±27) min in ORT, 42.2 (±23.2) min in ART and 39 (±14.7) min in MIX group. Average number of attempts (Ast) to stand was 1.8 (±0.8) in ABD group, 3.1 (±4.7) in ORT, 1.8 (±1.2) in ART and 1.8 (±1.2) in MIX. Recovery time (TRec) in ABD group was 102.2 (±36.5) min, ORT 70.1 (±36.5) min, ART 72.2 (±24.8) min and MIX group 66.6 (±19.1) min. TRec differed (p<0.05) between ABDand other groups. Three-point assisted recoveryfrom anesthesia showed to be a safe procedure during horses’ recovery. This method is easy to apply and well tolerated by horses regardless of the surgical procedure.

Background: Balanced anesthesia achieved with combinations of inhaled and injectable drugs administered systemically or in loco-regional anesthetic blocks, is widely used in veterinary medicine. The use of anesthesia and/or local analgesia has already demonstrated benefits in the performance of elective orchiectomy in different species, there is no literature that evaluates the use of the maropitant intratesticular route. The present study evaluated the cardiorespiratory variables and analgesia produced by intratesticular blockade with maropitant, lidocaine, or dextroketamine during the trans-operative period along with the discharge and anesthetic recovery of dogs that underwent elective orchiectomy. Materials, Methods & Results: Used twenty-four dogs from routine elective orchiectomy, considered healthy based on the results of clinical and hematological tests. The animals were randomly divided into three groups and was applied intratesticularly 2% lidocaine at a dose of 1 mg/kg (GL), 5% dextrocetamina at a dose of 2.5 mg/kg (GC), or 1% maropitant  at a dose of 1 mg/kg (GM). Anesthesia induction was performed with propofol (to effect), and stabilization of inhalational anesthesia was achieved with 1.7 V% of sevoflurane diluted in 100% oxygen administered through a calibrated vaporizer and appropriate anesthetic system based on the animal's weight, being kept under spontaneous ventilation, After induction, we waited 10 min for stabilization of exhaled anesthetic concentration and then administered one of the treatments intratesticularly. After five min from the local block the surgical procedure was started during up to 15 min. Heart rate (HR), respiratory rate (RR), systolic arterial pressure (SAP), diastolic arterial pressure (DAP), mean arterial pressure (MAP), oxygen saturation of hemoglobin (SatO2), end-tidal carbon dioxide partial pressure (EtCO2), end-tidal sevoflurane concentration (EtSevo) in exhaled air, and body temperature (T°C) were measured before intratesticular administration of the agent and at specific time points during surgery, in addition to assessments of analgesia and evaluation of discharge and anesthetic recovery. Statistical analysis was performed using the Kolmogorov-Smirnov test (P > 0.10). The parameters HR, RR, SAP, DAP, MAP, T, EtCO2, and SatO2 were evaluated by analysis of variance (ANOVA), followed by the Scott-Knott test (Software R® 3.2.0 - 2013), considering a significance level of P < 0.05. The results did not show inter-drug differences for the evaluated variables.Discussion: It was decided not to use premedication (MPA), so that we could accurately assess the analgesic effect of drugs, lidocaine, dextroketamine and maropitant, on intratesticular block during elective orchiectomy. In this study we demonstrated that these drugs promoted analgesia, because the trans-surgical values were relatively lower compared to baseline and within physiological limits for the species. In addition, it was noted that local analgesia used was efficient since even at the time of ligature and the incision spermatic cord which is described in the literature as the most painful part of the surgical procedure. The post-anesthetic recovery and discharge were quick in the absence of MPA, local analgesia without residual effects and the use of sevoflurane. The sevoflurane has a very low blood gas coefficient solubility, resulting in a recovery fast. Therefore, we can conclude that all of the drugs promoted analgesia and cardiorespiratory stability as well as rapid anesthetic recovery for elective orchiectomy in this species.

Semen was collected from four rams, using artificial vagina and viability%, motility% and plasma membrane integrity% were measured. Fresh ejaculates (n = 32) were separated by modified swim-up separation using modified human tubal fluid medium. Four fractions of supernatant were collected at 15-minute intervals. The mean volume, mass activity, concentration, motility%, viability%, normal morphology and membrane integrity% (HOST +ve) of fresh semen were 1.0 ± 0.14, 4.1 ± 0.1 × 109 spermatozoa/ml, 85.0 ± 1.3, 89.4 ± 1.0, 85.5 ± 0.7, 84.7 ± 0.5 respectively. There was no significant (P>0.05) difference in fresh semen quality parameters between rams. The motility%, viability% and HOST +ve % of first, second, third and fourth fractions were 53.4 ± 0.5, 68.2 ± 0.3, 74.8 ± 0.3 and 65.5 ± 0.4; 55.5 ± 0.4, 66.2 ± 0.4, 74.5 ± 0.3 and 73.6 ± 0.3 and 66.7 ± 0.5, 66.8 ± 0.5, 65.2 ± 0.4 and 74.7 ± 0.5 respectively. The motility%, viability% and membrane integrity% of separated semen samples differed significantly (P<0.05) between four fractions. The mean motility% and viability% were significantly higher (P<0.05) in third fraction (74.8 ± 0.3%), whereas the mean HOST +ve% was significantly higher (P<0.05) in fourth fraction (74.7 ± 0.5). All quality parameters of separated spermatozoa were significantly (P<0.05) lower than that of fresh semen. The pregnancy rates were higher with fresh semen (71%) in comparison to that of separated sample (57%).Bangl. vet. 2016. Vol. 33, No. 2, 62-70
