Abstract
Heparin is widely used as an anticoagulant solution for maintaining arterial catheter patency. In humans, increasing evidence suggests that heparinized saline solution (HS) has no advantages over a saline (0.9% sodium chloride) solution (SS) in maintaining arterial catheter patency. To date, no studies have been conducted on the effectiveness of these solutions at maintaining arterial catheter patency in veterinary medicine. The objective of this pilot study was to determine the feasibility of a study and to report the treatment efficacy comparing HS and SS for the maintenance of the dorsal pedal arterial catheter patency during direct arterial blood pressure measurements in anesthetized dogs. Client-owned dogs undergoing abdominal surgery were allocated to two groups to receive either a continuous infusion of HS or SS through the dorsal pedal artery, and the arterial pressure waveform was monitored during general anesthesia. Our feasibility outcomes included the proportion of the screened veterinary patients that completed the study and the success rate of arterial catheter placement. The clinical outcomes were assessed by the number of catheter-flushing procedures, occlusion rate, the duration of the initial catheter-flushing procedures, and the duration of catheter occlusion. Of the 51 dogs screened, 41 (80.4%) completed the study. The success rate of arterial catheter placement in the HS and SS groups were 87.5 and 80.0%, respectively. There were no differences in the number of catheter-flushing procedures and occlusion rate between groups (28.6 vs. 20.0%, relative risk [RR]: 1.429, 95% confidence interval [CI]: 0.472–4.323, P = 0.719 and 14.3 vs. 15.0%, RR: 0.952, 95% CI: 0.217–4.179, P = 1.000, respectively). No differences were found in the probability of time to the initial catheter-flushing procedure and occlusion between groups assessed by the Kaplan-Meier method (P = 0.546 and P = 0.867, respectively). This study revealed the feasibility of a study comparing HS and SS for dorsal pedal arterial catheter patency during direct arterial blood pressure measurements in anesthetized dogs. Clinical outcome analyses were underpowered and thus, could not determine the meaningful differences in treatment efficacy between the groups. However, the information gained from this study provides insight for future study designs.

Izer J, Wilson R. Comparison of invasive and non-invasive blood pressure measurements in anesthetized female Dorset cross-bred lambs (Ovis aries). Res Vet Sci 2020; 132:257-261. [PMID: 32688102 DOI: 10.1016/j.rvsc.2020.07.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2020] [Revised: 07/02/2020] [Accepted: 07/09/2020] [Indexed: 10/23/2022]
Abstract
The purpose of this study was to determine the level of agreement between invasive and noninvasive blood pressure measurements in anesthetized, non-surgically manipulated Dorset cross-bred lambs. Twelve healthy female Dorset cross-bred lambs, weighing 37.3 ± 7.4 kg (mean ± SD) underwent isoflurane anesthesia for simultaneous measurement of systolic arterial pressure (SAP), mean arterial pressure (MAP) and diastolic arterial pressure (DAP) from an invasive blood pressure source and a noninvasive oscillometric source (O-NIBP). The femoral artery was catheterized for invasive blood pressure measurements, while noninvasive blood pressure was measured from a cuff placed on the antebrachium. The Bland-Altman method was used to calculate agreement between SAP, MAP and DAP measurements. The bias ± SD between SAP, MAP and DAP measurements was 3.6 ± 12.0, 4.9 ± 9.1 mmHg and 4.1 ± 8.0, respectively. The 95% limits of agreement for SAP, MAP and DAP were - 19.9 to 27.1, -13.0 to 22.8 mmHg, and - 11.7 to 19.9, respectively. Overall, agreement was poor between femoral IBP and O-NIBP monitoring techniques in anesthetized Dorset cross-bred lambs, with O-NIBP underestimating the femoral IBP. Arterial blood pressure should be most accurately measured using an invasive blood pressure monitoring technique in lambs undergoing isoflurane anesthesia.

Abstract
BACKGROUND The purpose of this study was to identify the consistency of invasive dynamic blood pressure (BP) monitoring between the superior mesenteric artery (SMA) and the common carotid artery (CCA). METHODS Eight male Sprague-Dawley rats were cannulated in SMA and CCA simultaneously for BP monitoring, respectively. The abdominal aorta was prepared for the induction of BP change through clamping/de-clamping by a microvascular clip. The dynamic BP monitoring was performed by a polygraph system. Systolic blood pressure (SBP), diastolic blood pressure (DBP), and mean arterial pressure (MAP) values would be recorded during different time periods: the baseline (T1), the increasing period after clamping (T2), the platform period during clamping (T3), the decreasing period after de-clamping (T4), and the final platform period (T5). Three trials were performed on each rat with 15-minute intervals between consecutive monitoring. RESULTS Systolic BP showed no significant differences between SMA and CCA. However, significant difference was found in diastolic blood pressure except at T5 (P=0.534). Mean arterial pressure of two arteries were significantly different only at T1 (P=0.015). The strength of association was significantly high between BP measurements through SMA and CCA (P<0.001). The Bland-Altman analyses showed that mean bias of MAP changed no more than 5 mmHg and standard deviation less than 8 mmHg during T2 and T4, respectively. CONCLUSION The study indicates SMA might be an alternative site for invasive BP monitoring during abdominal aorta occlusion and release, especially in cerebrovascular-related research.

Chronic obstructive sleep apnea accelerates pulmonary remodeling via TGF-β/miR-185/CoLA1 signaling in a canine model. Oncotarget 2018; 7:57545-57555.

Abstract
Chronic obstructive sleep apnea syndrome (OSAS) is considered to be associated with pulmonary diseases. However, the roles and mechanisms of OSA in pulmonary remodeling remain ambiguous. Thus, this study was aimed to elucidate the morphological and mechanical action of OSA in lung remodeling. In the present study, we employed a novel OSA model to mimic the OSA patient and investigate the role of OSA in pulmonary remodeling. We showed that pulmonary artery pressure of OSA group has no significant increased compared with the sham group. Nevertheless, we found that fibrotic tissue was predominantly located around the bronchi and vascular in the lung. Additionally, inflammatory cell infiltration was also detected in the peribonchial and perivascular space. The morphological change in OSA canines was ascertained by ultrastructure variation characterized by mitochondrial swelling, lamellar bodies degeneration and vascular smooth muscle incrassation. Moreover, sympathetic nerve sprouting was markedly increased in OSA group. Mechanistically, we showed that several pivotal proteins including collagen type I(CoLA1), GAP-43, TH and NGF were highly expressed in OSA groups. Furthermore, we found OSA could activated the expression of TGF-β, which subsequently suppressed miR-185 and promoted CoL A1 expression. This signaling cascade leads to pulmonary remodeling. In conclusion, Our data demonstrates that OSA can accelerate the progression of pulmonary remodeling through TGF-β/miR-185/CoLA1 signaling, which would potentially provide therapeutic strategies for chronic OSAS.
