The effect of body position on intraocular pressure in anesthetized horses.

Objective: To evaluate the effect of four recumbent body positions on intraocular pressure (IOP) in anesthetized normal horses.

Animals Studied: Ten nonglaucomatous adult horses.

Procedures: Intraocular pressure was measured with a rebound tonometer in both eyes of standing sedated horses (baseline), then under general anesthesia during four randomized recumbent body positions, including Trendelenburg (Tr; 15-degree head down), reverse Trendelenburg (RTr; 15-degree head up), dorsal, and lateral; only the superior eye was measured in lateral positions.

Effects of inspired oxygen concentration on ventilation, ventilatory rhythm, and gas exchange in isoflurane-anesthetized horses.

Objective: To compare the effects of 2 fractions of inspired oxygen, 50% and > 95%, on ventilation, ventilatory rhythm, and gas exchange in isoflurane-anesthetized horses.

Animals: 8 healthy adult horses.

Procedures: In a crossover study design, horses were assigned to undergo each of 2 anesthetic sessions in random order, with 1 week separating the sessions.

Effect of anesthetic breathing circuit type on thermal loss in cats during inhalation anesthesia for ovariohysterectomy.

Objective: To compare the effects of a nonrebreathing circuit versus a reduced volume circle anesthetic breathing circuit on body temperature change in cats during inhalation anesthesia for ovariohysterectomy.

Design: Randomized, controlled clinical trial.

Animals: 141 female domestic cats hospitalized for routine ovariohysterectomy.

Evaluation of a real-time, continuous monitor of glucose concentration in healthy dogs during anesthesia.

Objective: To evaluate the accuracy of a real-time, continuous glucose monitoring system (CGMS) in healthy dogs undergoing anesthesia for elective ovariohysterectomy or orchiectomy.

Animals: 10 healthy dogs undergoing routine elective surgery.

Procedures: A CGMS was placed and used to obtain calculated glucose measurements before, during, and after anesthesia in each dog.

Comparison of anesthetic induction in cats by use of isoflurane in an anesthetic chamber with a conventional vapor or liquid injection technique.

Objective: To compare 2 techniques for induction of cats by use of isoflurane in an anesthetic chamber.

Design: Prospective, randomized study.

Animals: 51 healthy cats.

Accuracy of an oscillometric blood pressure monitor during phenylephrine-induced hypertension in dogs.

Objective: To examine the agreement between direct arterial blood pressure measurements obtained from 2 arteries and indirect blood pressure measurements obtained with an oscillometric blood pressure monitor (OBPM) during normotension and phenylephrine-induced hypertension in dogs.

Animals: 16 male Beagles.

Procedures: In anesthetized dogs, arterial catheters were placed in the lingual and dorsal pedal arteries for measurement of arterial blood pressure.

Comparison of recoveries from anesthesia of horses placed on a rapidly inflating-deflating air pillow or the floor of a padded stall.

Objective: To compare recoveries from anesthesia of horses placed on a conventional padded stall floor or on a specially designed air pillow.

Design: Prospective study.

Animals: 409 horses (> 1 year old) that were anesthetized for surgical procedures during a 37-month period.

Effects of atracurium on intraocular pressure, eye position, and blood pressure in eucapnic and hypocapnic isoflurane-anesthetized dogs.

Objective: To determine effects of atracurium on intraocular pressure (IOP), eye position, and arterial blood pressure in eucapnic and hypocapnic dogs anesthetized with isoflurane.

Animals: 16 dogs.

Procedure: Ventilation during anesthesia was controlled to maintain Paco2 at 38 to 44 mm Hg in group- I dogs (n = 8) and 26 to 32 mm Hg in group-II dogs (8).

Comparison of the cardiopulmonary effects of anesthesia maintained by continuous infusion of romifidine, guaifenesin, and ketamine with anesthesia maintained by inhalation of halothane in horses.

Objective: To compare cardiopulmonary responses during anesthesia maintained with halothane and responses during anesthesia maintained by use of a total intravenous anesthetic (TIVA) regimen in horses.

Animals: 7 healthy adult horses (1 female, 6 geldings).

Procedure: Each horse was anesthetized twice.
