Anesthesia

OBJECTIVES: Anatomical and methodological detail is lacking regarding local anesthetic peripheral nerve block techniques for distal pelvic limb surgery in cats. The aim of this study was to develop, describe and test nerve block methods based on cadaveric dissections and dye injections.

OBJECTIVES: The aim of this study was to assess retrospectively the efficacy and complication rate of hindlimb peripheral nerve blocks (PNBs) in cats.

The aim of this blinded, randomised, prospective clinical trial was to determine whether the addition of magnesium sulphate to spinally-administered ropivacaine would improve peri-operative analgesia without impairing motor function in dogs undergoing orthopaedic surgery.

This is a retrospective study evaluating femoral-sciatic nerve blocks (FSBs), epidural analgesia, and non-regional analgesia (NRA) in dogs undergoing tibia-plateau-leveling-osteotomy surgery. Thirty-five records met the criteria for each of the FSB and epidural analgesia groups. Seventeen anesthesia records met the criteria for the NRA or control group. The parameters reported were: isoflurane vaporizer setting, rescue analgesia/anesthesia drugs received, heart rate, systolic blood pressure, and recovery quality (0-4, with 0 being poor and 4 being good).

OBJECTIVES: To compare the effects of regional anaesthesia and opioid administration on adrenocortical and glycaemic responses, postoperative pain and recovery quality in dogs undergoing stifle surgery.

STUDY DESIGN: Prospective, blinded clinical study.

ANIMALS: Forty-five dogs anaesthetized for tibial tuberosity advancement or tibial plateau levelling osteotomy, and 15 healthy dogs undergoing non-invasive orthopaedic diagnostic procedures.

This is a retrospective study evaluating femoral-sciatic nerve blocks (FSBs), epidural analgesia, and non-regional analgesia (NRA) in dogs undergoing tibia-plateau-leveling-osteotomy surgery.

The analgesic efficacy of liposomal hydromorphone (LE-hydro) was tested in dogs undergoing limb amputation. The positive controls (n = 10) received subcutaneous (SQ) hydromorphone (0.2 mg/kg) and 1.5 mL of blank liposomes before surgery; fentanyl continuous rate infusion (CRI), 5-10 μg/kg/hr IV, during and for 24 hr after surgery; and a fentanyl patch at extubation. The negative controls (n = 7) received SQ hydromorphone (0.2 mg/kg) and 1.5 mLs of blank liposomes SQ before surgery, fentanyl CRI (5-10 μg/kg/hr IV) during surgery but stopped at extubation, and a fentanyl patch at extubation.

OBJECTIVE: To compare early postoperative analgesia in dogs undergoing unilateral tibial plateau leveling osteotomy (TPLO) that received bupivacaine via preoperative femoral nerve block (FNB), combination femoral-sciatic nerve block (F+SNB), or lumbosacral epidural (EPI).

STUDY DESIGN: Randomized, blinded, prospective clinical trial.

ANIMALS: Forty-five client-owned dogs undergoing unilateral TPLO.

The intra-articular administration of lidocaine is a frequent practice in human orthopaedic surgical procedures, but an eventual absorption of the drug into the bloodstream can lead to toxicity, mainly concerning the central nervous system and the cardiovascular systems. The purpose of this study was to determine the pharmacokinetic profile and the safety, in terms of cardiovascular and CNS toxicity, of lidocaine after intra-articular administration to anesthetized dogs undergoing arthroscopy.
