  • Anesthetic approach in two dogs with gastric dilatation-volvulus syndrome
    Jordi Eisenhower Hernández Pinilla, John Yeiber Rengifo Herrera, Diego Alejandro Ospina-Argüelles, Ricardo Andrés Ramírez Uscategui
    Revista De Investigaciones Veterinarias Del Peru, 2026
    This case report describes the anaesthetic management of two dogs with gastric dilatation-volvulus (GDV) syndrome. Both patients received a partial intravenous anaesthesia (PIVA) protocol combined with a multimodal perioperative analgesic strategy. Patients were admitted to the emergency department due to restlessness, abdominal distension, and non-productive retching lasting two and three hours, respectively. Historytaking and clinical examination findings suggested GDV, which was confirmed via radiographic study. After initial stabilization, an exploratory laparotomy was performed to correct the condition through gastropexy, with an additional splenectomy in one patient. A PIVA protocol was implemented with infusions of propofol, fentanyl, ketamine, and lidocaine, complemented by inhalation anaesthesia with isoflurane. Cardiopulmonary parameters were monitored intraoperatively without significant alterations. Pain was assessed using the Glasgow Pain Scale in the immediate postoperative period, indicating adequate analgesic coverage. No cardiac arrhythmias were detected, and the patients were discharged after 48 hours without complications. In conclusion, the PIVA and multimodal perioperative analgesia protocols apparently resulted effectively for the GDV management and preserved the lives of patients. However, further studies are needed to confirm these findings and optimize anaesthetic protocols for these critical cases.

    Cuniculus paca, a South American wild rodent with zootechnical potential, requires anesthesia for management procedures. However, limited information is available regarding safe monitoring of this animal under anesthesia. This study aimed to compare with gold standard invasive method and validate non-invasive blood pressure measurements using an oscillometric monitor in Cuniculus paca. Eight healthy adult females undergoing general anesthesia for follicular aspiration were included. Systolic, diastolic, and mean arterial pressures were measured simultaneous using, oscillometric non-invasive monitor with its cuff placed on the radial artery and an invasive catheter placed in the dorsal metatarsal artery. Measurements were compared using the t-test, correlated by Pearson test, and analyzed using the Bland-Altman concordance test. The results indicated that only systolic pressure measured by non-invasive oscillometric methos was similar to the pressure measurement by invasive method (P=0.6372, r=0.5969, bias 0.59±20.9 mmHg); while mean and diastolic pressures were underestimated by the non-invasive method. In conclusion, non-invasive oscillometric monitor provides a valid and reliable method for systolic blood pressure measurement in Cuniculus paca under general anesthesia.
  • Transversus abdominis plane block in a canine undergoing to foreskin oncologic surgery
    Diego A. Ospina-Argüelles, Luís Vergara S., Patrícia De Aquino
    Revista De Investigaciones Veterinarias Del Peru, 2023
    Se describe el manejo analgésico realizado en un Boston Terrier macho de 4.5 años sometido a resección de carcinoma de células escamosas en el prepucio. Se efectuó el bloqueo del plano abdominal transverso con abordaje lateral, usando bupivacaína (0.25%) como anestésico local; complementando un protocolo analgésico multimodal que también incluyó acepromacina, meloxicam, dipirona, fentanilo, ketamina, propofol e isoflurano. La nocicepción transquirúrgica fue evaluada mediante el comportamiento de la presión arterial media no invasiva y la frecuencia cardiaca. La analgésica posoperatoria inmediata se valoró con la escala compuesta de dolor de Glasgow. Los parámetros cardiovasculares intraoperatorios se mantuvieron estables. La puntuación de la escala de Glasgow permaneció debajo de los limites indicativos de dolor. Se sugiere que el bloqueo locorregional asociado al protocolo analgésico empleado permitió obtener un consumo de isoflurano estable, y evitó el empleo de analgesia de rescate transquirúrgica y posoperatoria en el paciente evaluado.

    La incidencia de hipotermia perioperatoria inadvertida es una de las principales complicaciones perianestésicas en caninos. El objetivo del presente estudio fue evaluar la incidencia de hipotermia perioperatoria inadvertida en 49 perros sometidos a anestesia general inhalatoria. Al finalizar el periodo preanestésico, transanestésico y postanestésico, se registró la temperatura corporal, de acuerdo con los siguientes rangos: hipertermia (>39,5°C), normotermia (38,5-39,5°C), hipotermia leve (38,4-36,5°C), hipotermia moderada (36,4-34,0°C), hipotermia severa (<34°C). En preanestesia, el 65% de los animales mostraron hipotermia leve y 2% hipotermia moderada. En transanestesia, 55% de los animales tuvieron hipotermia leve, 37% hipotermia moderada y 6,1% hipotermia severa. En postanestesia, 59% de los animales tuvieron hipotermia leve, 29% hipotermia moderada y 6% hipotermia severa. Se encontraron diferencias al comparar la temperatura basal, con la final transanestésica y postanestésica, respectivamente (p<0,001); del mismo modo, se obtuvieron diferencias al comparar la temperatura inicial, con la final del periodo transanestésico (p<0,001). Por otra parte, no hubo relación estadística entre las diferentes clasificaciones ASA, los procedimientos realizados, el sexo y los rangos etarios evaluados, así como tampoco hubo diferencia en el tiempo de extubación frente al tipo de procedimiento realizado. Los resultados de este estudio sugieren que, bajo las condiciones aquí planteadas, la incidencia de hipotermia preanestésica es mínima, mientras la aparición de hipotermia transanestésica y postanestésica de carácter leve, moderada y severa es mayor.
  • Effect of two cyclical alveolar recruitment maneuvers on different parameters of non-invasive microcirculatory monitoring in dogs

    Revista U D C A Actualidad and Divulgacion Cientifica, 2019
    Alveolar recruitment maneuvers (ARM) are important in reversing the formation of perioperative atelectasis; however, its performance is subject to significant hemodynamic changes. The present study evaluated the effect of two cyclic alveolar recruitment protocols, by increasing positive end-expiratory pressure (PEEP), on three parameters of microcirculatory monitoring in 28 anesthetized dogs. Animals were randomly assigned to one of three groups, according to the ARM to be performed, thus: Group 1, short protocol (SP) recruited with PEEP of 10cmH2O; Group 2, long protocol (LP) recruited with PEEP of 20cmH2O; and Group 3, control protocol (CoP) ventilated with PEEP of 0cmH2O. For each maneuver, the central-peripheral temperature gradient (TG), capillary refill time (CRT) and pulse oximetry (SpO2) were evaluated, in four times namely: T1 (Pre-anesthesia), T2 (pre-recruitment), T3 (30 min post-maneuver) and T4 (60 min post-maneuver). In T2, CRT values showed a significant decrease (p<0.05), with respect to baseline time. Subsequently, in the T3, a significant statistical decrease of the TG for the SP group was evident compared to the other treatments; while in the T4 the CRT presented a significant decrease (p<0.05) for LP group versus the other treatments. It is suggested that under the conditions presented here, the protocol of ventilation with PEEP increments of up to 20cmH2O is the ARM of choice as it does not produce alterations of clinical importance in the microcirculatory parameters evaluated.
