To determine and compare reference intervals of the strong ion gap (SIG) in a group of healthy dogs determined with 2 different equations. ⋯ The 2 equations used to calculate SIG yielded significantly different results and cannot be used interchangeably. The authors believe SIG(2) to be a more accurate reflection of acid-base status in healthy dogs, and recommend that this calculation be used for future studies.

Case ReportsSudden generalized lung atelectasis during thoracotomy following thoracic lavage in 3 dogs.
To describe sudden onset of generalized pulmonary atelectasis following thoracic lavage in 3 dogs. ⋯ Generalized atelectasis should be considered a possible complication of thoracic lavage performed during thoracotomy. In the cases presented here, it is suspected that pre-existing reduction in lung volume (due to inadequate ventilation, surgical compression, absorption atelectasis) was exacerbated by the addition of the lavage fluid to the thoracic cavity. This pre-existing lung collapse is believed to have resulted in reduction of lung volume and that further reduction below the critical closing volume occurred following instillation of saline into the thorax resulting in the subsequent development of generalized atelectasis. The performance of regular arterial blood gas analyses and different ventilation protocols may have prevented the marked atelectasis that was observed in these cases.

Direct intra-abdominal pressures and abdominal perfusion pressures in unsedated normal horses.
To determine whether direct intra-abdominal pressures (IAP) and calculated direct abdominal perfusion pressures (APP) are location dependent within the abdomen of standing horses. We hypothesize that IAP will be increased and calculated APP will be decreased at a ventral abdominal location (V) when compared to values obtained from the left (LFl) or right flank (RFl). ⋯ IAP and calculated APP are location dependent. These data provide new information regarding abdominal pressure profiles in standing healthy adult horses.

Randomized Controlled TrialThe effect of using an impedance threshold device on hemodynamic parameters during cardiopulmonary resuscitation in dogs.
To investigate the hemodynamic effects following the use of an impedance threshold device (ITD) in a canine model of cardiopulmonary arrest. ⋯ Use of the ITD resulted in favorable changes in hemodynamic parameters in dogs undergoing CPR. The ITD may be a useful adjunct during CPR in dogs and warrants clinical evaluation.
